I've spent the last months building a videogame: Cardume [1], its a pvp game where 2 players battle using a swarm of thousands of cells. It uses Reynold's boids, Couzin flocking behaviors and diffuse fields to generate a mini ecological simulation each game. The sim is pretty well optimized, handling 12k agents at 60fps in a medium hardware machine. It also has some pretty cool visuals. Any feedback appreciated, the Store went page online this last week and I'm still working on the presentation.
Two weeks ago presented current state of KEIBIDROP at Pass The SALT 2026, and now I am planning the push for the next version 0.4.0.
KEIBIDROP: Makes remote files appear as local (it hides the network latency in order to let you open and edit a peers file without downloading it upfront or re-uploading it fully back).
For version 0.4.0 I am planning multi-user support, using UDP (QUIC) instead of TCP as the networking layer, optimization of live-edit regions of files, and to test it even more for data heavy workflows.
With the help of AI & LLMs I restarted working on some of my older side projects. I updated the code and did a landing page for Printable Mockups (a free, open-source drag-and-drop tool for creating device accurate wireframes and sketchpads that you can export as PDFs, print, and sketch on by hand) https://github.com/alexadam/printable-mockups
I plan to add more features soon.
My wife and I continue to work on Uruky [1], a simpler Kagi alternative, based in the EU.
Last month we reached 200 monthly active accounts (we’ve passed 250 now), and last week we launched support for XMR/Monero payments via ProxyStore [2]!
You can also see in our homepage that more independent bloggers and privacy-minded people have written about us!
The main differences between Uruky and Kagi, DuckDuckGo, SearXNG, etc. are visible in the footer (right side), but one huge difference is that with Uruky, after being a paying customer for 12 months, you get copy of the source code (licensed as BUSL,into AGPLv3 in 2 years — a suggestion made here in HN)!
Uruky is paid and you can get a free 2h trial when you signup if you pass a proof-of-work captcha (another suggestion made here on HN, and it uses a local Altcha).
Our main challenge continues to be discoverability and outreach because we want to do it ethically. Ideas are welcome! We’ve been sponsoring open source projects, open source maintainers, and indie, small-web, and privacy-related websites and applications. This month was Caddy [3]!
Feature-wise, for July we’ve already shipped a lot of visible and less visible things. We’re currently looking into increasing our own index, focused on indie/small web, and plan to add a couple of new search providers in the upcoming weeks.
Thank you for your kindness!
[NO-AI]: There is no generative AI product or service, here.
Still noodling on https://skaldmaps.com, which lets you compare and rank all US ZIP codes, counties, and census tracts to find good places to move to and/or invest in.
Based on an early prototype that helped me find our current house.
I released Humm[1] last week. Realtime speech-to-text with a focus on privacy. No backend, no telemetry - just a fast, nicely designed app wrapping local stt models.
I've been migrating marginalia search off docker-compose and onto systemd.
Between NUMA-concerns and the need to use multiple public IPs, I'm coaxed into a pretty exotic setup no matter what I choose to go with. Was pretty finnicky to set up, but it seems to work pretty well all said and done. Systemd is certainly feeling less floaty than docker (and even moreso kubernetes, which was never an option).
I also shaved like 10ms off response times since I no longer need an additional reverse proxy to deal with docker's networking magic, and can point nginx straight to the network namespaced services' IPs.
This in service of sequestering all wide domains (as in having tens of thousands of subdomains) to their separate crawler and index partition, as their (per top-domain) rate limits are part of why crawls take so long for the main crawler. Couldn't do that on docker because its ipvlan management is so jank you need spare IPs to reliably restart services.
I was an experienced game designer and producer (mostly RTS and narrative RPG). Some years ago, my career was derailed by major health developments. Since then, I haven't been able to work as I once did. I didn't expect I'd be able to meaningfully contribute to a game again.
Earlier this year, a colleague encouraged me to experiment with Claude Code. So now I have a little game project. :) Being unfamiliar with genAI, I chose something modest so that I'd more likely be able to push it to a fairly polished state.
Tentatively called Vestiges, it's a single player 2D roguelite strategy game with meta progression, some narrative, and a card minigame (the latter inspired by work I did on Star Wars: Knights of the Old Republic II). It's set in the near future. You are using software (the game) to navigate a person's digitized mind, reading their memories.
I hope to have a playable demo within the next month or so.
Thanks! I've been hesitant about Steam because of the strong anti-genAI sentiments there. (And the initial fee to set-up a game's page.) You are right, though, and I probably should just push past my reservations.
(When I began this effort, I was just enjoying feeling productive again and didn't have any real plan to release. But I've been pleased enough with how it's been coming along that I've started seriously thinking about it.)
That's useful context, thanks. I might be in a grey area on that front. Vestiges has no genAI-created images, textures, etc. Pretty much all of the (non-text) visuals are generated at runtime using Godot's 2D vector drawing capabilities.
(I've considered trying to find an artist to work with to have professional 2D art.)
We are working on our two site-search search engines Monocle Search [0] and SearchCue [1]. The former is squarely aimed at people using Squarespace, whereas our newer offering SearchCue is aimed at anyone with a site that wants to add search.
We used Meilisearch as the search backend in the beginning but have since replaced it with a quite sophisticated search stack built around Tantivy [2]. We now support crawling and indexing of pages, most common office documents and PDFs, run OCR and feature extraction of images you might have, offer typeahead search with the aim of giving you providing answers as fast as you can type, as well as more classic agentic/conversational ai search.
There have been quite a number of interesting optimization challenges to solve in case anyone is interested. We have search nodes distributed around the globe to provide the lowest possible latency regardless of where the end-user sits.
We are also working on some other smaller side projects, but they aren't quite ready to launch yet.
1. Translating 1000s of NeoLatin, Chinese and Sanskrit books for the first time
At the Embassy of the Free Mind in Amsterdam, we’ve created https://SourceLibrary.org, a collection of over 15,000 translations of Renaissance and premodern books in NeoLatin, Chinese, Sanskrit, etc. There are a lot of beautiful books to look at — and you can use it with Claude code. API keys available: https://SourceLibrary.org/developers.
2. Replicating the design patterns of contemporary AI services
I’ve created a web app, desktop application and API for organizations needing European hardware and data protections. It’s a nice interface on top of Scaleway in France, so low carbon too. See https://makemode.eu
Support, feedback or even participation on these projects is very welcome.
I was annoyed by the speed of docker on Mac’s, so I took a journey and decided to rewrite everything about it. DD was original working name and I’m in process of rebranding. But we can run docker on Mac’s with no vm. And its destroying qemu. We have plenty of new features that are comming. Rendering native apps, workspaces, much more.
Thank you! A project like this was on my wishlist for a long time.
Colleagues looked at me like I'm weird when I was saying containers without a VM should be possible on macOS. I switched to a Linux laptop because I couldn't stand the experience of working with Docker on macos.
I wonder if some of the macOS sandboxing features can be used instead of relying solely on the JIT
Yeah docker Mac expirience is pretty bad especially the x86 is just painful, and to your comment (about security), it should not really matter in practice, in fact we used both, but goal really is to run secure sandboxes that are processes without performance impact.
The biggest addition in the past month is initial support for ngspice netlist export — you can now take a Circuitscript design and export it to a SPICE netlist for ngspice simulation. This is a step toward closing the loop between describing a circuit and verifying its behavior, all from the same source file.
I have also added bus support, which makes wide parallel connections like data/interface (I2C, SPI, etc.) lines much less tedious to connect up.
Recently I produced and tested a 161-LED charlieplexed array in Circuitscript, using nested for-loops to generate the array instead of copy-pasting every LED and connection by hand. I plan to write a blog post soon to document this design.
As always, the motivation is to describe schematics as code rather than by clicking around graphical CAD tools (KiCad, Allegro, Altium, etc.). I want to spend time on the design itself, with code expressing the intentions clearly and reviewable in text.
Feedback welcome, especially from anyone frustrated with graphical schematic tools! If you have a KiCad design you'd like to convert to Circuitscript, please reach out to me. I'm looking to test the limits of the language and happy to help with the conversion.
Today I'm carrying on looking for a literary agent to represent me for my young adult speculative fiction. Long after human civ collapsed, crows have evolved to speak and are undergoing their own industrial revolution when they discover an asteroid heading towards earth. My 10 year old read it for the first time yesterday and loved it. That's made it all worth it already even if it doesn't get published.
Tonight is a meeting of a local group growing hemp locally, processing and spinning by hand to make an item of clothing locally and sustainably between us all.
Just spent the weekend at a wing chin gathering with some incredible people. They showed me so much I need at least 2 weeks to think about it all.
Apart from that I’m starting college to study therapy and counselling soon so I'm trying to read up to be a bit prepared.
Working on Push Realm (https://pushrealm.com) the AI solution sharing network. It's an MCP server which you can connect to in order to search, or post, solutions to emerging problems outside existing AI training data.
The original idea was just "Stackoverflow but for AI agents" but I have tweaked it a lot, learning that humans and agents work in very different ways.
There are multiple potential benefits, the most important to me is avoiding token waste. Why are we all burning tokens solving the same issues with frontier models if we can simply share solutions?
Secondary to this, because each solution logs the model which made the initial post AND subsequent edits, it will hopefully become a helpful guide to the specialties of each models, long term. If one model confidently posts solutions but another always finds important security caveats, for example.
A while ago, I realized that most new agent harnesses being built must be hosted on your machine or on a VM--in other words the agent needs a full OS process at all times.
But we do not have good harnesses being built that are multi-tenant, do not use compute while they are paused, but are are still as powerful as, say, Claude Code or Codex, OpenClaw.
So I set out to build one. I realized that the best substrate for these kind of agents are durable workflow engines. I'm currently supporting Temporal. AFAIK much of OAI agent infra is built on Temporal too. My harness is decidedly not just another agent SDK, but rather a battery-included product.
Just a personal project right now but it's a music metadata aggregator.
I find that nobody really knows how to do this. Machine learning can detect some song attributes well (bpm, ez right?) but it's inconsistent with some things (eg mood, spotify valence)
I prefer to only add metadata that I can rely on: track credits & instruments (when available), lyrics, bpm / "energy" and genre. At least that's what I've got for now. I'm not adding anything unreliable.
So far I'm able to pick a genre, artist or even better, song and it gives me a list of tracks that are similar. I can alter the weights of "era", "instruments", "genre".
So far i haven't run old school NLP on the lyrics but that's the next step. It's likely to be far more informative than "valence"
Anyway, not public, still very alpha but I like it and find it useful.
I'm working on a tool to automatically sync your work-in-progress music from your DAW (digital audio workstation, like Ableton Live, etc), to your phone. Basically a workflow tool for musicians and producers! Also has some quick share/feedback functionality too. Would love some feedback since it's still in really early stages. Already integrates with Ableton, Bitwig, Cubase, and GarageBand. https://trackid.com.
I used to work at Native Instruments, and super happy to now work on something for myself instead.
I am continuing to work on Akariq [0] which provides travel eSIM data plans to 180+ countries around the world. I have had many paying customers over the past few months from Vietnam to Mexico to Europe and US of course. The three benefits of using Akariq are
1) No app, no user account which leads to literally 3-click install
2) Full transparency - you know what you are getting. A lot of other eSIM providers hide details like unlimited plan speed caps etc
3) I connect to the best network available in the country. For example, someone like Airalo would connect to VTC in Vietnam, I offer Viettel which is the undisputed local network king.
And obviously, I am 2-3x cheaper than Airalo and the big players.
I like but for many of my regular destinations you are still 2-3x more expensive than what I can trivially find myself, especially longer visiting times and more data.
Thank You! Can you please tell me your destinations?
I plan to make the higher volume data plans cheaper very soon. I'm happy to provide you temporary code to make it cheaper for longer visits you have soonish. Can you e-mail me at `hello@akariq.com`? I don't see an e-mail on your profile.
The one thing I want to add is that cheaper also depends on quality. So for example, if you look at Vietnam - I may not be cheaper than Airalo. But ... a big but, I offer network on Viettel while Airalo does on VTC. So, I am cheaper for what you get for the quality. In addition, I don't route data via HongKong or China to make it cheap. I have in country / region networks for like 87 countries and I keep improving [0]. Very few providers on the market can guarantee that.
I can confirm that you are completely right about Vietnam mobile networks. I could only reliably work after getting a real viettel sim. Even viettel branded stores sell some bootleg sim to tourists that work terribly.
The problem with eSIM is that usually there is no way to judge the quality until you buy one, so people sort by price and choose the cheapest. If your solution offers the best network in the country then I’m interested, because even at x2 or x3 price it doesn’t matter much compared to the other expenses when traveling.
Not sure how you can convince customers outside the hn bubble.
My passion project is an LP-sleeve-sized music streamer built around an ARM compute module, a custom PCB carrier board and an industrial 17" square display.
This is a really cool idea. Been thinking of a way to introduce my daughter to my old LPs without her wrecking the vinyl, and this might be a good compromise!
I heard an episode of the Odd Lots podcast about HayWire (haywireag.com), a site that pulls public data from government PDFs + APIs, uses LLMs to parse it and turns it into an easily readable website that has all of the latest info on hay prices.
The host made an offhand mention that there's probably a bunch of other similar sites that could be created with all the of useful but difficult-to-access government data out there. That sounded interesting, so I thought I'd give it a whirl!
All pretty fascinating topics to learn about, plus it's been interesting to see how much of the website setup I can fully delegate to Claude. With Cloudflare to buy domains and put the sites up, a Google Service Account with access to Google Search Console and GA4 to create those properties and a Buttondown API key for weekly email sending, it's almost all hands off for me. Though it refuses to take control of the browser and create a new Buttondown account, which I was surprised is a red line.
As someone who's constantly on the look for new music to discover and being very deliberate about the things I'm listening, I needed a better way to organize the albums I want to listen to, listened and liked. And also I would like to see the discoveries of other folks who I know I like.
What does machine readable mean? And what does easily accessible by AI agents mean? Can agents read regular web pages? As in, what is the difference between this and regular web pages?
I'm working on TTZ, a sort of, pardon the expression, next-gen terminal protocol.
I wanted a middle ground between web apps and Terminal UI that allows for things like raster images, vector graphics, simple audio support and file transfer; to let me move more apps and workflows from web apps to a lighter experience.
I have an old laptop that I love and is very nice to use, but since it has only 2 GB of RAM, using multiple web apps is out of the question. I live on the terminal and SSH, but it has its own limitations, like spotty support for images, no audio at all, and ReGis (for vector graphics) support is not available in a lot of terminals.
I've recently finished implementing both client and server libraries for multiple languages (with the help of AI), and right now I'm in the process of fully testing and squashing all bugs and inconsistencies. Next, I will port a couple of applications as a proof of concept.
I plan to publish the source code very soon to receive feedback.
Just finished Veritas - Truth Across Cultures[1]. The idea is that many different cultures have written sayings that are basically the same. Similar to how one would give more credence to more than one person saying the same thing, the same is true for cultures. So, this is like my catalogue of what diverse cultures agree on. I have been promoting this book. [2][3]
I've been working on Source [1], an experimental Git server written in Go.
Source stores repositories in a database rather than a filesystem [2]. The primary goal is to rely on databases for durability, replication, and distribution, rather than introducing complex distributed filesystem infrastructure into the stack.
I am working on an online Talmud to explore the old text in new ways! Its been a pet project of mine for over 4/5 years, and to my knowledge its the only attempt to blend the classic format of the text (Tzurat Hadaf) and AI enhanced commentaries sourced from the classical texts
Update: Hopefully this can help those who completely misunderstand the nuance of this ancient text (usually from antisemitism) to better understand what they are reading.
I'm working on a collection of networked games, around the central theme of a lockstep deterministic network model with 'delay frames' (between acting directly on user input and progressing actual shared network state).
- Neon Swarm, a take on the classic lemmings game, with multiplayer versus and coop modes
- Serpents, a snake game (where you eat food, grow a tail and need to avoid this growing tail), with inertial movement and multiplayer
- Spirits, an homage to N++, where you work together to get someone to the exit, while avoiding enemies, figuring out how to open doors, and so on
- Pilots, a multiplayer asteroids battle with homing missiles
Each game solves the network delay problem (the problem of providing immediate feedback to user input and hiding the fact that actual changes to shared state are delayed) differently, and it has been very interesting to work through a bunch of different approaches to this.
If anyone else here is working on multiplayer network games, I'm very interested in setting up a regular "play each other's games" session.
The idea is that regularly playing with other game developers will help develop a kind of 'scene' (where you get a group of people together who make work in public but really aimed at each other, pushing and unblocking one another to become bolder and better at an accelerating rate, as described here: https://www.henrikkarlsson.xyz/p/scene-creation-engines ).
Happily continuing work on https://cardcast.gg. It's a way for my friends and I to play Magic: The Gathering online using a webcam. Spelltable has been neglected by WoTC, and we wanted more features, so I rolled my own (and learned some Computer Vision stuff in the process!)
Most recently I rolled out automated card tracking, so there's no more need to click on cards to know what they are, they just automatically scan on a set interval.
I also moved over to using livekit for the service, and man, I should've done that sooner.
If you play MTG, I'm looking for more people to come give me feedback and contribute. Feels like something others can benefit from!
I saw the options out there were not fully open source, or had other limitations so I started working on this better one.
Based on Debian, apps are docker containers.
I do work to adapt current open source apps, but it's so great to make them available as one click install.
I want to make it easy to run on a cloud VM or an old PC kept in the pantry.
There are so many cases for self-hosting now that we need to make it easier to do
I’m working on https://gnooma.com, a lightweight tool for reducing knowledge drift in teams.
It introduces a new document type called a gnoom: a living document that knows who has read it. When the document changes, read confirmations reset, so you can see who is up to date.
I built it because important decisions kept getting buried in chats and then discussed all over again.
It’s a free beta and doesn’t require an email. Curious if anyone else has this problem. I’d also appreciate any feedback on Gnooma.
I am working on ShopSpec (https://shopspec.io/), a tool for designing bookshelves and cabinets. Enter the dimensions and it generates the parts, cuts, sheet layout, and build steps.
I built it because I wanted to spend less time drawing boxes in CAD and more time building them. Still early and I'd love feedback from other woodworkers.
My side project is now codebase explainability. I basically don't buy the premise that we just have to give up on comprehension as code generation scales; I just think that text is too limited by itself. So going a step deeper than asking Claudex "teach me this project", but having it produce a navigable snapshot of what's going on.
Big bang prototypes have been pretty awful, even after feeding the LLMs huge documents / wishlists / descriptions of how it should work, etc. Part of the experiment was giving LLMs some leeway to make product decisions with a lot of north star guidance, but AFAICT they are really bad at this. I also tried basic bottom-up efforts, which have been better but obviously more tedious. Now I'm trying to find a more scalable bottom-up approach that is more LLM-accelerated
But maybe you should checkout the tools it’s based on, sem - https://github.com/Ataraxy-Labs/sem and ultimately treesitter. They at least give a more structured approach to dealing with code than simple text.
Any promising techniques so far? I’m working on a rather large monorepo and very few people on the team are managing to keep up with it. Looking for ideas to improve comprehension.
I’ve been playing around with aligning drone footage to flight paths. I'm really interested in the idea of representing a video as a volume, planning to do something similar with non-drone video too.
I'm creating a "spy mission" for my granddaughter. Using an Axiometa Genesis Mini with some modules for gating access. Real-world challenges, enter results into the Genesis, get directions to the next challenge.
I am trying to involve family members' specialties and interests so she can elicit help from each person: entomology, mechanical engineering, etc.
All that for her to discover the Secret Planned Activity the following day (visiting a theme park.)
I started toying with perlin vector fields as a level design tool for a game idea, then became more interested in visualizing them than the game they were meant to support. this weekend i realized i think im making a (short) ~game in which you control a dust mote riding air currents, trying to gather enough water to fall back to earth as a raindrop
I'm continuing to build out OneBusAway Cloud (Heroku for public transit), just like last month. https://onebusawaycloud.com. Since last month, the overall polish and feature completeness of the product has improved substantially, and we're starting to see meaningful inbound interest.
It's a little webapp that solved a problem I had when ordering PCBs: I was too cheap to buy the stencil when ordering the PCBs from China, but then I regretted it when I had to paste by hand. Because of this, I did the PCB Designer -> DXF -> CAD -> Add margin -> Add outline -> Print workflow by hand, but that became very tedious, so I built this to automate it.
It runs entirely on your local machine and it is hosted on Cloudflare pages, with the only costs for me being a domain name.
Nice. I tried to submit a project on the former. However CloudFlare seems to be blocking me from submitting the form.
This is a common issue for all of us in Viet Nam though, not sure if there's anything you can do your side. I'll figure out how to get my submission through later :)
Sorry about that, wasn't aware that this was an issue for people in Vietnam. If you want, you can direct email me at contact[at]openaltfinder[dot]com, or you can reply here with the project you wanted to submit.
I released my first web game on CrazyGames recently https://mechacraft.io with about 40 CCU and I'm now working on my second one https://nickvanurk.com/voidfall. I'm also available for remote work :)) (discord: jycerian)
I'm continuing to work on Personal Finances Python [1], a book that teaches software developers how to track their finances using the Python ecosystem, Double Entry Bookkeeping, and a bunch of plain-text files.
Apart from that, I recently started getting interested in the AT protocol ecosystem, so I built a directory [2] for discovering ATProto alternatives to mainstream/centralized products.
I'm working on https://gatewai.studio in my free time - it is an agentic workflow engine for content creators.
There are 40+ nodes that can be used to generate and modify images, videos, audio, or vector graphics. Some of them include Crop, Resize, LUT extraction, Levels, Audio Compressor, Ken Burns, Mesh Warp, Recorder, Noise Gate, Compositor and Signal Builder.
It also supports signals for dynamic and time-based configuration values for the nodes. For example, making blur strength change from 30 to 0 gradually in the first 2 seconds of a video.
It uses a WebGPU pipeline for rendering and a homebaked engine for workflow processing.
It is free to use except for the AI nodes and workflow agent. It is not officially released yet, and feedback would be very valuable.
Continuing to build my olive oil tracking site (https://www.extravirginvault.com/) and pipeline. Freshness is king in the world of olive oil, and I hope to highlight to people they can find high quality, fresh olive oil produced near them.
It's been received well from producers and olive oil enthusiasts (e.g. looking for specific chemistry, cultivars and similar oils) but I feel like I've been shadow banned from Google - I seem to get more traffic from DuckDuckGo and Bing.
Working on gisti.ai which eventually will be a fleet of Product and Customer Operations AI agents that continuously analyze customer interactions, identify the churn risk and automatically route the right actions: code fixes to engineering, product insights to PMs, and operational tasks to customer operations.
Today, Gisti ingests customer feedback from every channel your customers already use, synthesizes it into a prioritized, evidence-backed list of opportunities, and lets product teams interact with an AI agent to explore, validate, and act on each one. We are building Gisti with a philosophy of complete automation for specific workflows.
We are looking for Design Partners, please hit me up at shubham@gisti.ai. I will be in SF late August if you prefer in-person meetings.
Please ping me / email me if you are interested in a demo / demo account for deeper analysis.
I made it specifically to bring back what was amazing about the old internet, and do it as authentically as possible. takes inspiration from old internet messageboards, usenet, bbs, and pubnix hosts. it has sealed mail, boards, an rss reader, built-in media player, custom profiles, a links directory, and quite a bit more.
it's just a little hobby art project for me but i've really appreciated talking to like minded people in a calm space.
Thank you! That's the idea, and even though its been a slow burn, the conversations have been interesting and rewarding. One of the funniest proof of concept so far was, someone asked how to route a guitar body to fit a new bridge on a network with maybe a dozen active people at the time. Within like a day, a total stranger with an actual woodshop and eight spare guitars showed up with real technical advice and offered him a discount on one of the guitars. Maybe it was a fluke, but it really struck me, and there have been a number of small interactions since that one that really remind me why I loved the early web so much.
Awesome, looking forward to seeing you on the boards. Yeah, we have a decent little group of active posters and we've been adding to that number slowly but consistently since I put it online a few weeks ago.
It's been fun and I've learned starting a community is a lot harder than it looks. Maybe I'll write a post on what I've learned sometime. TLDR and probably no surprise to most: making the software is the easy part.
I am working on hammer https://thehammer.io/ , it is a voice device that I have build and have been using for past several months for texting and getting answers to my questions via AI chatbots.
I started with the idea of replacing my phone with a texting device that can still keep me connected but realized phone has became utilitarian that it is not possible to replace it.
I still have to take my phone when I am outside but when I am home or at work, I now use hammer exclusively to text or to get answers. The most benefit I have got is that I don’t have the urge to open my phone and go on endless scrolling binge.
This month I continue working on to refine my coding agent harness https://github.com/vinhnx/VTCode. Recently, I've added back Anthropic Claude Fable 5 and OpenAI GPT 5.6 models family (Sol, Luna, Terra). Fortunately, I've had support from the open source community and VT Code has advanced. I hope you give it a try.
I've just released in beta, a web-based application called Verse Draft: https://versedraft.com
I wanted to create an all-in-one writing studio where fiction writers can keep all the details for an entire universe in one place while crafting stories, novels, movie scripts, TV series, or stage plays.
I also wanted the ability to allow for the limited use of AI in a way that only functions as a sounding board and does not write for the user; Where fiction writers could have access to tools such as a virtual assistant that they can converse with about their stories and world-building, but without it writing anything for them.
There is also an option to use the application without any AI tools at all.
I'm slowly building an IDE with mentor/skill-level awareness baked in.
I've noticed that juniors and new hires often fall into an impostor-syndrome trap when reading an unfamiliar codebase or reviewing a senior peer's PR. Documentation helps, but it usually runs into the curse of knowledge: it's written by someone who's spent so much time in the code that they've lost sight of what it's like to be new to it.
I've always liked the rubber-ducking process, and mob programming too, so I'm trying to combine both into a modern AI-enhanced form:
- "Duckies" with distinct personalities (really, skills) that each specialize in a particular kind of problem
- "Teachable moments" (working title): small bubbles that surface something novel, tangential, or foundational as you work
- Skill-level detection and a routing model, so the app doesn't overwhelm or annoy you with explanations you don't need
Each duck also runs on a tiered memory model, rather than one flat context window. There's a core memory, essentially the duck's resume, defining what it's actually skilled at. Above that sits a longer-term memory for company standards and code style, and a separate long-term memory scoped to the project itself. Short-term memory then covers whatever task or feature is currently in flight. The idea is that a duck should reason more like a team member with a real employment history than a chatbot that forgets everything between sessions.
It's called Duckies AI (https://www.duckiesai.com). It’s very rough, working locally, but not in a state I’m ready to ship yet. I'm hoping to ship an alpha soon. Turns out there are a LOT of table-stakes features an IDE needs.
I love this. I have been building and IDE for myself. My non-technical team wants to use it after using lovable and things like that. I started building a dialect of JavaScript to make more approachable but that seems impossible the more I get into it.
I started down this path, although with a VS Code plugin, but I didn’t find the ability to visually tie into the text editor with chat modals/bubbles. It’s likely what I would pivot to if I don’t like the amount of effort necessary to build the basics.
As an engineering manager and later a director, a regular and often difficult task was assigning ROI to projects that had recognizable but diffuse impact. It's easy to calculate a dollar figure for certain projects by projecting additional conversions or revenue. It's harder for a security or SRE project that doesn't have a direct impact on those things, but can help reduce risk or empower a bunch of other teams to operate more safely or move more quickly.
I have been working on a set of tools and standard formulas that can be applied to these cases and demonstrate a more accurate view of a team's or department's overall ROI. The plan is to open-source the bulk of it, but provide a hosted service for folks who don't want to manage it themselves.
I'm working on a no upload, no account, no server-side preprocessing online viewer for schematics, PCB layouts, 3D boards and BOMs called ECAD Forge -> https://ecadforge.app/
A cliché project, but working on a photo library browser that works in a way that I want it. Technically, the interesting thing is a UI that is reusable across all of my target platforms (desktop, mobile and in-browser with WASM). Rust+GPUI is the first platform I've seen that makes this possible with a reasonable performance and quality.
I am working on Spreadsheet Preview, embed and preview Excel files in any website/web app. Just like PDF.js for pdf files. Check it out at https://spreadsheetpreview.com
A macOS menu bar app to alert when apps start using too much resources and drain your battery. Helped me diagnose many leaking Chrome tabs and macOS bugged services.
This is a Chrome extension that records lots of details in a usage session. Stuff like network calls, console logs, screenshots and also optionally screenshots and user narration
Tools like this exist, but every one I tried is uploading the session details somewhere in their cloud and try to monetize this.
So I built the version I wanted: free, open source, and local. There is no account, no backend, no telemetry. Sessions live in IndexedDB in your browser and exported as a zip.
What it records:
* Clicks, typing, page changes, network requests and responses, console errors screenshots, video with sound
* Your voice, transcribed and placed next to what you were doing at the time
* Annotations: Arrows and boxes you draw on the page's screenshot
Note: Passwords, auth headers, and tokens are masked at capture time
All events are lined up in a timeline with timestamps
At export you pick a detail level with a live token estimate, so a long session still fits your model's context window.
Currently working on
Agentry(https://agentry.run/)
Runtime, connection, and deploy layer for building internal apps and automations with AI. You can build anything that you can build with Lovable, Replit etc. Your model, Your harness and your own Laptop/Server
I've been building a text editor. It uses a server-client model, with native/terminal/web clients using a shared (local) server instance. It integrates LSP/tree-sitter/ripgrep/Git/etc, and has a concept of 'workspaces' to easily switch between projects.
I spend less time in an editor now, but it's been satisfying being able to take features I've enjoyed from other editors and customise - and it's oriented a bit more towards exploring code than editing. Key-bindings are arranged such that bare letters are for motions, Shift- variants are then used to extend selections, Ctrl- bindings are for buffer mutations, and leader-prefixed bindings are application level (e.g., opening pickers).
I’m working on [Homestead](https://myhomestead.dev), which is my OSS solution for building personal apps. You can build web-apps and Homestead will handle backend, agent support, authentication, notifications, and a bunch of other stuff.
I’ve used it to build a grocery store list, credit card perk tracker, address book, mini-golf scorecard app, and a bunch more. It’s really helped having all of the “platform” stuff handled for me so I can just focus on the app.
I'm building a Go to WASM reactive UI framework called Goowee. Fine grained signals (no VDOM), components run once, SSR and hydration built in. The JS bridge is about 200 lines. Still experimental but I've thought about it thoroughly and have used it for the landing page of the project and some other projects of mine.
I know Go UI frameworks have a long history of not quite getting there. The bet I am making is that WASM is now fast enough, the tooling is mature enough, and the fine grained signal model avoids the VDOM overhead that held earlier attempts back. Would love an honest critique of whether the framework actually solves the problem and whether it's usable for other's development experience.
Neat! I did a fair bit of toying with Go's WASM target early on and was able to port a couple neat things to the web. The sheer size of the WASM output though was a limiting factor for me, and I kind of stopped toying with it a number of years ago.
Are you using the built in WASM target? I've been told Tiny Go's WASM build target is worth investigating but haven't tried.
Yes, the size of the binary is quite big (~4MB for the landing page) but it's a trade-off that I'm taking with this approach and I think there will be ways to optimize for size.
I'm currently using the built-in WASM target but Tiny Go is one of the items that I have on v1.0 road map. Will give it a shot and see if it actually helps with the size without affecting any performance.
I built a fully locally hosted language learner app. It build language lessons based on a 4 year college curriculum, using a local LLM, Qwen TTS, local STT, and comfyUI image gen. I formulates themed lessons, around 'interesting' stories, generates dialogue, images, audio, quizzes, and pronunciation tests. Each lessons progress is tracked and new lessons are generated daily to reinforce concepts and extend past lesson story lines.
Overall it acts like a 'Choose your own adventure' book, but you learn while doing it. Currently supports Spanish, French, German, Japanese, and Simplified Chinese. Runs on a 4060 16GB card.
Makes it easy to use Claude Code or Codex interchangeably across multiple computers. Personal editions are free, I have a hosted commercial cloud (workgroups share AI history) and commercial self-hosted option available.
It has macOS and Linux clients and I released a guide for setting up the source-available, self-hosted cloud option this week: https://contextify.sh/docs/self-hosted/
I am thinking about the other AI cli environments and providing support for those as well.
Triply periodic minimal surfaces are the golden standard in thermal management, acoustics, and even medical applications. But minimality itself doesn't contribute much to practicality. We use them because they are simply studied better than the non-minimal surfaces.
So I'm studying the non-minimals. They are much more governable, what I link to is a demo of a surface builder with two levels of control. Next, they are conjugatable including conjugations with different period of self (that will be the following paper), they generalize nicely to non-periodic or partially periodic surfaces, and they work in other space configurations. E. g. I'm now playing with bi-periodic curves that cover the 2D space with self-replicating hexagons.
If all that I'm experimenting on today in 2D will turn out well in 3D too, we'll have a whole new direction in implicit modeling.
Kind of tangent of what everyone else is doing but making a minifigure/garage kit painting site.
If you're in the hobby, the issue is that keeping track of paint and color combinations is annoying and is very mind numbing since wet paint color differs from dry point colors, how colors combine due to transparency of the layers, and different companies have different binders/pigments.
Currently have the paint combination setup and trying to get minifigure gaussian splatting setup from an image (Used to work in gaussian splatting for a while and actually figured out how to improve vggt to get a better one-shot)
AI resume spam has absolutely ruined hiring. I've seen countless stories of hiring managers complaining about receiving thousands of resumes within an hour of opening up a new job listing. Likewise, good qualified candidates are getting drowned out by loads of customized junk. I'm building a tool for the recruiters and hiring teams to combat this and bring some sanity back to the already challenging process. The general idea is to introduce a small bit of friction that will hopefully be not-too-impacting for legit applicants while stopping bots from proceeding.
First iteration is ready to fly, just working out the infrastructure at the moment. Hoping to drop this on Show HN soon. If anyone is interested in test driving this prior to launch, I've temporarily added my email to my profile.
Have spent the last month giving the UI a bit of a modernisation refresh and simplifying/improving some elements based on early user feedback. There's also been a boat load of performance improvements in the dirarisation and document generation pipeline.
In the past few weeks, experimenting with a custom ai agent running entirely in the browser with sandboxed tools exec.
The core is built in Rust, a native CLI is built on top for local experimentation but the most interesting part is the web version: the core is built to WASM and get augmented with many tools in the JS land:
- OPFS access (read, list, edit files)
- Sandbox Python exec (Pyodide in WASM)
- Sandbox DuckDB exec (DuckDB-WASM)
- Draw charts
- Show images
- etc
OpenAI Completions compatible API providers are supported.
But if you want a full local and sandboxed execution of the whole agent, the web version bundles also wllama to serve local GGUF models (with WebGPU optional support).
Very cool work. I've been seeking solutions for running an agent in the browser for building artifacts on my project, which is a web artifact tool library called Exhibit. I'm starring this for later.
Oh nice! I’ll take a look at it, I was thinking of implementing such mecanism in Cooper (I don’t know where it’s going, exploring the possibilities and practical usefulness)
I'm working on a website directory (intrasti.com), not really sure what the direction is other than I'd like to celebrate the best of the internet in a way that isn't pay to win, manipulative, or anything like that.
It's a slow business and engineering catalyst that I'm making progress with behind the scenes each day. Suffice to say I'm taking the scenic route!
Currently working on a unified website submission flow for submissions and topic creations (topics are collections of websites) and after that I'll be looking into overhauling the whole site focusing on accessibility and how I can make that a great experience.
It's like a BuiltWith for Government. I am tracking all UK government spend and building a picture of software and rising/falling trends of various products in the government.
I worked as a government supplier and found it hard to find out what tech/solutions are in place without inside knowledge. My idea is that by opening the data, I can help more suppliers compete and foster innovation.
Something very small and simple compared to other ambitious projects here :)
A TUI to control a crazyflie nano drone. This is mostly a rust learning project - but insanely fun because it leads to something flying through my living room.
I am working on a local first LLM frontend that saves all chats directly to your hard drive and ships in a single index.html file artifact that you can self host.
No code to show yet. I'm taking the time it requires.
Recently launched https://hellbox.com (formerly Font Proof) and am still actively working on it. It is a native macOS app for font proofing. It watches your type design software like Glyphs, RoboFont, and FontLab or any font file or designspace on your machine and reloads the font proof when you save.
I'm working on a Claude Code governance tool that allows to define deterministic policies for tool call that can be enforced across a fleet and will be in effect even when individual users run with --dangerously-skip-permissions
MatGoat (https://matgoat.com/en/): a software for managing BJJ and martial arts academies that it's both easy to use and have everything they need like assistance tracking, payments, communications, etc.
It's going quite well so far with growing MRR each month.
Lately, I've been trying to focus more on marketing, and sales. I might try ads soon as well.
I am speaking to initial customers and from my initial pain at my day job it was going to be a way to be "Lovable for your existing product" . But it also seems like it might turn into "internal cloud to host dashboards non-technical people are making with Claude".
I'd love to talk to anyone that's in Product or Ops or Sales or Account Management or Customer Success who'd either like to make changes to their existing product without the need for a developer. Or maybe they have thrown something together with Claude and have no idea how to "get it into production".
Enjoying the work on MyTraL - sovereign athlete / personal training log: https://mytral.fitness/
I went on sabbatical to fulfill my dream project - consolidating years of training logs. I'm enjoying the technical challenges involved - digitizing paper hand written logs / visual models, navigating the maze of athletic metrics with their crazy trademarked names and multidimensional models. Having fun building AI coaches: agents ranging in character from Al Pacino in Any Given Sunday to the coach from my teenage years, utilizing ICL model-based predictions, ... and more.
The best part is the rush of memories while ingesting my own history - photos and recordings I completely forgot, as well as navigating data shared by friends.
This month has Strava & LeCol everesting challenge - signed up and added support that suits my needs to MyTraL. Good times.
This is my side project turned solo bootstrapped startup that I've been working on over the past 2.5 years. Pastmaps has been solely a US-focused platform since it's initial launch but I'm currently working on launching to the UK and Ireland within the next week. If all goes as planned then I should have a first wave of 30K fully digitized, hi-res, and fully georeferenced 1800s ordnance maps available soon to help folks discover the history all around them.
I'm likely going to need to start building out my own global LiDAR dataset next though. My coverage for the US is quite stellar thanks to the data provided by the USGS' 3DEP program but I'm way out of touch with what's available and possible in the EU. It's gonna be a challenge but I'm excited to dive in.
Self hosted media platform with similarity search, face search and clustering, a great fun media player with shuffle, VS mode where you rank your media resulting in an elo, remote access to app over the web, a TikTok style "swipe" mode of your own media. Started as just a good media viewer over 5 years ago but I just keep adding things. Has a small patreon following so people seem to like it. https://lowkeyviewer.com/
* A simple exercise tracker that my wife requested from me (https://daily-menu.hosgeldin.click/) - later I will build a menstruation tracker that is connected to the Daily Menu.
* My magnum opus, "MyApps" (https://myapps.ideasofhakki.com/) - This is no less than an OS running in your browser, equipped with whatever "Apps" written in it. I am building it with GunDB and Svelte and foundationally it will be a web of apps running completely in your device (i.e. offline first), with privacy and data security built-in.
I released 3 games my friend designed, and built a game framework in WebAssembly for building them. Some 9 or 10 months ago I asked my friend (legendary game designer Mike Elliott) if he wanted to work through his backlog of designs he has that he'd love to see brought to life. I'm very protective of my family life and dedicate a lot of my time to it, and have a normal full time job, and so LLM-agents really enabled being able to make stuff like this happen in a reasonable timeframe just working on and off in my free time.
I started them with ebitengine (Golang) but got somewhat frustrated with its web builds, and so built my own thing for small games that I want to work great on mobile or native PC, but also on web. I call it NanoGame, the host is written in Rust and the games are AssemblyScript. I've ported a number of other small games I had written to it as well, but haven't released any.
Two of the games I released a couple days ago were actually the ebitengine versions, but have partial ports to my framework, and the third I released the version using my stuff.
https://scramblequest.app - ebitengine, word search game where you slay monsters with the words, has a long campaign as well as a daily challenge and unlimited play
https://wordpeek.app - ebitengine, another word search game, this one reveals pieces of a picture and your goal is to guess the picture
https://playsilhouette.app - my own framework, this is a simple matching/hidden object(ish) game, more for kids
I'm working on hexora, a library that detects malicious Python code using static analysis and machine learning.
Recently, I've added a simple ML model to filter out false positives. In the last month, I found and flagged more than 40 malicious Python packages.
Unlike the LLM approach, my library is not susceptible to prompt injection and deobfuscates Python code. Where LLMs see "obfuscated code, potentially harmful", my library decodes it and sees what's happening inside.
Automated network port change detection. Scan17 provides a solution to the question:
So your CTO decides to outsource firewall management - and the vendor carelessly leaves a network port open, exposing your production database. How does your team find out before an attacker?
Think of it as nmap port scan diff-ing. If a network port goes from closed to open you get an email or webhook alert. There is a REST API for automated workflows and privately hosted engines will be supported for some plans. There is a wait-list form on the website if you want to stay in the loop.
If you work in infosec / cyber security and are interested in being an early product designer / beta tester, let's chat! See my profile for how to get in touch.
Desktop app bundled with an ai model and a local-first agent so nothing leaves your machine.
Last week I interviewed non-technical people about their experience with AI agents. Many couldn't even use them at all. Either they didn't want to share private data with ChatGPT or company policy prohibited it.
For those of you working with sensitive files – contracts, client records, financials, HR docs – I'd love to hear how you handle this today: simone [at] breadboards.io
A daily meditation "instrument". I'm a big fan of Waking Up but I've kinda outgrown the catalogue. I know what to do now. I just need a timer and a couple of prompts...
I’ve been continuing work on https://mybulkcards.com, a phone app and website for scanning, organizing, and searching Pokémon card collections, especially the thousands of bulk cards that my daughter and I have in our closet from playing.
The goal hasn't changed too much, make building decks easier by knowing exactly what you own and where it’s stored. You organize cards into boxes, search your inventory, search friends’ collections, and keep track of trades instead of digging through a similar closet of cards that my daughter and I search for.
The fun part has been the AI. I trained computer vision models that run entirely on the phone to detect and identify Pokémon cards. Training has become the slowest part. For the model that needs to be retrained every new release, I’m up to about 5 hours per epoch on my M4 Mac with 16 GB of RAM.
The Android app is currently in public testing with people from my local Pokémon league. It’s built with React Native, and I’m working on the iPhone version next.
Still lots to build, mostly around product and ux, and because a recent stupid mistake on my part, backups and deployment safeguards.
I've been working on Wattle (https://wattle.app) for the past six months or so.
It started out in life as a bunch of post-it notes for friends who were watering my plants while I was on holiday, which evolved into a long text message, a Google Doc, a static site, a simple CMS, then Wattle. The more I look around, it seems like there are lots of use cases, so I'm having trouble with my positioning.
"Digital guidebooks for vacation rentals, home swaps, sitters, carers, and more."
Funny, when I lent out my house I also covered it in PostIts.
When looking at a SaaS idea I always ask myself, "will this add enough value to compete with generic and free tool X?"
If your app is just pictures and text based (with AI search), I wonder if it adds enough value to compete with just a Google Doc that's also text and pictures (which surely also offers AI search). A Google Doc could also use comments to collect questions.
Visiting your home page, I was actually looking for AR (augmented reality) or plain camera powered features. E.g. point at a window sill and say "how do I open this?". Point at the washer controls and say "how do I do a fast wash? How long will it take?".
This could be especially useful for controls/labels in languages that the guest doesn't understand (easy to mistake bleach for detergent in Spanish for example). Maybe auto translation of all textual content and even pictures could be part of your app as well.
AR is something that I would love to see for myself!
For this particular scenario though, I've found that both hosts and guests responded far better to simplicity: a familiar UX (images/text) with a nice UI. Now that AI has become mainstream, adding this to search was also received well. Funnily enough, most of the past six months was spent culling features and streamlining/abstracting choices. The AI actually started out as multimodal and was reduced to text-only over time.
What I've learned from users is that a guidebook is non-critical until it is. When a guest can't figure out how the microwave works, they don't want to download an app, learn a new behaviour, and so on. They just want an answer as quickly as possible - from the host, or from a simple guidebook.
It's not so different from the host's perspective. Their focus is hosting, not creating the perfect resource. I added templates and "AI onboarding" (i.e. write a prompt / dump existing info as unstructured text) which people seemed to like. Turns out blank canvas syndrome is very real here as well. The AI organises existing info, creates placeholders for what's missing, and adds suggestions of what could be included.
When the guidebook fails to answer a question, it's logged so that the host can update it directly from the UI.
Completely agree with translation - it's on the list!
From the screenshot/device mocks on your site, I was under the impression that you were making an app for both host and guests to use. There's no 'browser chrome' visible in those pictures.
Could clarify that your app generates a site, or make that apparent from the screenshots.
I've been working on a web application for learning 倉頡輸法 https://demo.cangjieworkbook.com/ , no login required for the demo version (Cangjie Input method). It's a visual way of decomposing Chinese characters. It has a high initial learning curve so I've come up with a method based on the ways QWERTY is taught. I've added a few more texts and lessons in the last month. The most time consuming part is adding annotations to characters to show how they are composed, but it is worth doing. I already have a couple of users and they have given me helpful feedback. If you are interested, check it out and let me know how it goes.
https://vask.dev - websockets - Pusher alternative. It's Pusher compatible, but way cheaper and powered by Cloudflare.
https://tailstats.com - display data on almost any device (ios,android,macos).I've build this for myself so I don't have to build dashboards or mini-one-purpose-apps and clog menubar/workspace.
It also works with AI agents via API and MCP so agents can create interactive cards.
I'm working on a multiplayer RPG https://grimrain.com - calling it an MMO is quite bold, but the gameplay fits that genre. The game server is designed to be self-hostable too, so it's like Valheim meets OSRS
Part of my job is to approve / reject MCP servers based on how secure they are and whether they are suitable for use in an enterprise environment. I was tired of my team being called the bottleneck to AI adoption, so I set out to automate the whole process.
I periodically collect the MCP servers and every new version from the Official MCP registry and assign them a score based on 29 distinct criteria like runtime guardrails (e.g. destructive tools, over broad permissions, rug pulls), SAST scans and transport & trust model.
As a result of this exercise, I found that 1 in every 10 MCP servers is pretty much unusable (score 40/100 or below). 18% of the popular MCP servers with 1000+ GitHub stars contain one or more security issues. 184 servers to date have changed their tool definitions after publication, which may indicate a "rug pull" attack.
I built this for security minded people who also want to be at the forefront of AI adoption and for security teams who are tired to be called the bottleneck.
Browsing the index is completely free, you only have to request an API key if you want automated, programmatic lookups for any workflow.
I’m still working on a price API for the Counter-Strike 2 market that provides real-time & historical data.
Since my last post in February, I’ve gotten to ~25 paying users, which is cool considering it started as a fun project. Sorta a niche within a niche here.
The market is distributed across a bunch of 3rd-party marketplaces, and there's no 'simple' API that provides genuinely high-quality data for the few marketplaces that matter. It’s a surprisingly complex problem, which is probably why nobody else is bothering :).
It's been a super fun project, and I've been able to learn about collecting & managing a high (to me) scale of data, building an API from the ground-up, and creating my first 'commercial' website.
Interesting and I also really liked the mobile website. Just wanted to let you know there is a bug on the frontend where the navbar does not collapse back when the user changes the page like going to pricing, the page state changes but the navbar stays on top hiding the change
Still working on Study Engine and Nomnominees(more or less done for now).
StudyEngine is a webapp I'm using while doing my masters in comp sci. I upload lecture notes, textbooks, papers, etc. It then extracts topics and tracks my mastery of them over time. It uses an LLM to generate questions and flash cards. It loops in some newer learning science ideas. It tests recognition first(multiple choice), and then once a level of mastery is matched, it switches to recall. Working on adding RAG to it, so I can surface where in the source material something can be reviewed when going over quiz results. Currently just for me an some friends. If can get a good eval set up, I might work on optimizing cost and seeing if it could be opened up.
NomNominees is simple webapp that tracks James Beard, Great American Beer Festival, Festival of Barrel Aged Beers, and other awards. I use it when I'm traveling to find places to check out. Even just a cluster on a map shows me neighborhoods I might want to check out.
Constantly iterating through refinement and features. It's built on Rust + Tauri with a React frontend, in case anyone is curious.
I've created various open-source and commercial tools in the multimedia space over the last 10+ years and wanted to put it all together into something more premium with an IDE-like experience.
I frequently found myself needing to convert video files and everything is either paid, needs login, full of ads, or uploads your files. So I built my own tool that has none of that.
tscircuit! An open source framework for building circuits, we have a lightening fast autorouter so i spend lots of time debugging complex PCB routing problems
An "agent orchestrator" (or whatever you want to call it) that supports any cli agent. Trying to optimize for reducing cognitive load for working on different tasks at the same time with agents.
Currently doing final polishes on adding support for making it simple and easy to run agents and review the code remotely over ssh.
I'm working on a side project to clean up and fix EPUB files with transcription errors, incomplete or inaccurate metadata, and other issues. Users can accept/reject/edit the fixes as they go through it. I have the command-line interface and TUI working (thanks to Ratatui), but I'm still working on a Calibre plugin and web-based version using WASM.
A focused and functional service for event hosts to collect guest photos through a shared link/QR code that leads to an upload page. Think photo gathering for weddings, bachelor/bachelorette parties, corporate events, big birthdays, etc.
There are many of these out there, but I found most unintuitive ("too complicated for Grandma"), too featureful, and/or much too expensive.
And not an arcade game, but a multi-player throwback to a multiplayer shooter game my team used to play called nSnipes: https://github.com/linsomniac/isnipes
iSnipes does require downloading and running a server, the others you just play on the web.
I am building a solitaire solver for Zachtronic Solitaire. Especially the last one. It should allow you to take a pic of the screen and tell you if it's solvable and what the next moves could be.
I am working on a Jupyter notebook client for VisionOS. It allows for 3D data to be visualized on visionOS. Right now it supports point cloud data, USDZ models and Gaussian Splats. I am working on it to launch on the App Store. Sign up for more information at http://www.pulto.org
I've just finished this chrome extension recently: https://ypuf.com/
It helps me to automatically save a tab that's not been used in a while so it auto-closes it but saves it as well as having the ability to snooze a tab like how you'd do it in gmail.
Everything is locally stored with 100% privacy in mind.
I've started building a visualization tool for mobile robots using the VDA5050 communication standard.
There are some solutions already out there but most are either slow, resource intensive, or both. Especially for larger fleets of robots.
I'm using it to learn more about VDA5050, Rust and wgpu.
I am taking my limited time before next job hunt and using coding agents to create a wego board strategy game inspired by Escape From Tarkov, Advanced Wars, and PhantomBrigade.
We are creating an AI for science and engineering: https://vicena.ai
It's connected to all papers of course, and all kinds of scientific simulators and specialised models. But I'm currently in Shanghai talking to labs to join a CloudLab (and hopefully setting up our own robotic labs), so that AI can actually order real physical experiments that are executed cheaply, efficiently and seamlessly as tool calls.
Through experiments like autoresearch we have seen that AI is already, if not always smarter, at least more systematic than humans at following the scientific method relentlessly (hypothesis-experiment loop). Let's see what we can do by connecting it to the real-world :)
I've been building some sqlite plugins for playing with ngrams for text search. I'm not sure why, but I've learned a lot about the internal sqlite apis and it brings me a lot of joy. I would like to start a blog detailing some of this work but haven't found the time yet
I am helping a not-for-profit, [NavSahyog](https://navsahyog.org/), build a custom software for their entire operations and programs that also tracks longitudinal impact. The organization conducts programs for children in Indian villages after school to build live skills.
This is my second iteration because the first version felt like a simplistic fit and improvement over their existing vendor provided app.
I have now designed a domain model based on my understanding and observations. I have a day job so I can't spend a lot of time in sync with the team. I have created a web app where the NGO management can test scenarios (by recording voice), and the AI (Claude Agent SDK) runs it past the domain model. In case, there is a gap, they can persist the scenario. After every iteration, I read through the scenarios and assimilate them into the domain model.
I'm working on https://artifacts.iofold.com, a way to use artifacts (self contained html + optional assets like image/video/json) easily across agents, with feedback loop and docsend style wttribiti gates.
Have made it agent friendly enough that my teammates' agents can read and drop commennts on specs/storyboards etc, and my agent can close the loop by iterating with a new artifact version.
In summary, I pull public motion votings and do any kind of processing I want to give people a better insight in how the Dutch parties vote. There's a voting compass that gets a bit busy before elections.
It was a project by Erwin and I would like to continue the work.
I'm looking at the long-term image and have high hopes other countries would enjoy this too
It’s basically snake meets scrabble meets PvP stealing. It’s a novel idea and I think it’s cool it hasn’t really been done before :)
The issue is it’s too complicated, the onboarding is dogwater, and the aesthetic is too complex
So I’ve spent the weekend fixing onboarding, fixing and relaxing the visuals mix and simplifying mechanics.
I’ve also tested LLMs playing the game through a harness I wrote. LLMs get smashed, they can form words and steal, but they lose badly to conventional bots.
I’ll be exposing an LLM leaderboard on my next release (hoping this weekend) with links to game replays for the LLMs.
Would love for people to give it a try, give me some feedback, and say what you’d love to see on the roadmap.
I’m working on https://checkpost.dev, a lightweight and easy-to-use osquery manager. It is open source, easy to self-host, and ships as a single binary. It only requires osquery to be installed on the endpoints. Checkpost is readonly and doesn't make any changes on the enrolled hosts.
It can run adhoc or scheduled queries and send the results to ClickHouse, or store them locally in Parquet files and use DuckDB to browse the results. It can also initiate YARA scans and collect the results. It also supports policy evaluation and alerting.
I’m already happy with the current set of features, and I don’t expect to add many new ones. I want Checkpost to be something you can host once and spend very little time managing.
One of my goals while building it was to use it for device posture checks. Currently, alerts can be integrated with VPNs and proxies to allow or deny requests from devices that fail certain checks, but this requires manually parsing the webhooks. Over the next couple of years, I plan to focus on making those integrations easier and more seamless.
Edit: One major feature I’d like to explore is device identity and attestation using TPMs or secure enclaves. This could allow Checkpost to verify that requests are only coming from enrolled devices.
It’s a better code reader built on top of sem (treesitter). I’m getting a lot of massive PRs at work now, and this has helped a lot with reading them. It decomposes the changes into entities and sorts based on what has the most dependencies. This tends to put the most important functions first. Plus I can click through the dependencies for each function and mark things as reviewed as I’m reading them. It’s a big improvement over the GitHub review flow for me at least.
this looks incredibly useful! I've also run into similar problems with code review and been building similar tooling with the same idea (reconstructing the changes into entities, and finding focal/important changes), but haven't gone as far as this.
https://finbodhi.com — It's an app for your financial journey. It helps you track, understand, benchmark and plan your finances - with double-entry accounting. You own your financial data. It’s local-first, syncs across devices, and everything’s encrypted in transit (we do have your email for subscription tracking and analytics). Supports multiple-accounts (track as a family or even as an advisor), multi-currency, a custom sheet/calculator to operate on your accounts (calculate taxes etc) and much more. Supports price for most Indian investment vehicles and US stocks.
Most recently we added support for creating custom dashboards. You can compare return with leading/trailing/rolling charts for investment options and benchmark (create custom dashboards tracking nav and value chart of) your portfolio (or a subset of assets you own) and US stocks, etfs etc. And family dashboard (e.g. you can see networth, cashflows, income, use sheets at family level and more). See https://finbodhi.com/changelog for details.
I have a daily puzzle game called https://lettered.io and I’ve been playing around with shareable replay gifs via gifenc. It’s been fun trying to get good looking replays without sacrificing size for quality
The age of AI has been incredible for the daily game space because you can play around with ideas so much faster and riff to find something that works. On the flip side, there’s a lot more games that just rip off another idea and change some mechanic slightly to make it “new”
There's competition in the other TCGs, and of course a 2-sided marketplace is one of the hardest things to seed. So this is mostly just a project that I can put any fresh ideas into that I wouldn't be able to at my dayjob.
Pretty much just SwiftUI-like layout/style in TypeScript with a bunch of utility tools from other languages I like, like Rust's payload enums, table helpers, LINQ-like queries, state management, etc. It's framework neutral so it works with React, React Native, and Vue right now. Everything is just plain TypeScript that compiles to the DOM, so no HTML or CSS needed for most normal web apps, they can all be written in plain .ts or tsx files.
1. A compiler for real-time tensor processing (arbitrary DSP, ML). In something like LISP or Haskell, the goal is to compile lambda calculus for fast/reliable execution—as such, you can express a program in a fully general language that can represent any computation and execute it without explicitly modeling the lower levels of the machine. I'm building a compiler that does the same thing for the subset of programs that are guaranteed to execute on-budget. The effect: you write code that looks like DSP/ML math and it compiles/runs optimally with execution guaranteed by construction.
2. My take on an agent framework ... append only log + content hypergraph in Elixir, tools that regularly pull data from other services into Postgres—built as a kind of 'exoskeleton' around claude/codex so it's not competing with fast-moving tools.
I built my own weather prediction / visualization app: https://wx.rsp.li (on-device temperature lapsing, on device interpolation modes, user-selectable aggregations, etc…). One of these days I should do a writeup.
Same as last month for once - optimizing how well agents can work with a new language [1]. I've been able to 2-3x success rate and drop total tokens for complex tasks significantly (though the initial syntax dump is rough - need to do some ablation there to get it down).
The best part has been that I think it's significantly improved things for humans too; it's weirdly satisfying to be able to measure improved ergonomics. Also, since a big pitch/theory was that the language should be ideal for agents as a result of the original nice things for humans it was designed for, it's a relief to be able actually measure a concrete lift.
[1] https://trilogydata.dev/ - SQL with types, composable functions of arbitrary complexity, and a native semantic layer.
Primary idea is to evolve from SQL client to a Database Client, where users would be able to host queries, share queries and the work remains auditable.
Previously it was an SQL client, a PopSQL alternative. But I am trying to re-work the architecture so that it can support more databases, and services (query-as-service, query-as-reporting-job, etc).
It's mostly "public" data, but incumbent data vendors charge $90k+ for this data because it has to be acquired and aggregated from 3200+ US counties. This is a lot of work if you aren't using LLMs and agents to do much of the work for you.
I'm trying to make quality parcel data more accessible to everyone.
I'm working on https://topicle.com/ An alternative to Reddit that more aggressively polices bots, spam and astroturfing and has strong guardrails in place against bad moderation. No private profiles that bots use to hide, every mod action can be appealed, mod logs are public, LLM posts are blocked. There's so much obviously inauthentic activity and questionable moderation on Reddit, I decided to try addressing it.
This is amazing! Very refreshing in the age of AI to see so much manual building going on. Sadly I don’t have much time myself but I have several friends who would love this, I’ll pass it on to them.
Ohh this is the type of stuff that interests me although I am not a car fan but I like what you are doing with the aggregation/old-school DIY forums.
Good luck with your build and perhaps I might get interested in future too as I did once have a thought that having a custom car to me would reflect more cool-ness than an expensive one. I am really interested by small cars, perhaps retro. I imagine my favourite car to be somewhat like the car that Ryan gosling drives in La La Land.
but a cool project nonetheless, certainly thinking about it inspires a bit of car enthusiasm within me even though I am not that much of a car fan so much right now so a really cool project if it can help more people feel this spirit. good luck :-D
I have a question but how does building new (retro-inspired?) cars go about in terms of pricing. I feel like they might be too costly to get custom-built and that If I really ever in my life go about doing this, I would prefer DIY but I still imagine that it might be too expensive or hard to make a car. Are there any go-to cars which are easy/recommended within this space and how does it compare off economically and what are the technical expertise that you require with this type of stuff?
Once again, I wish ya good luck in the project and would love to hear your answers for some of the questions I have!
Thanks; much appreciated. I picked up an endless list of new build interests in starting the site and exploring different niche forums. Turns out I really like wooden boat builds, cyclekarts, intricate custom knives, handmade violins, the list goes on...
You're right that getting a car custom-built is where the costs add up quickly; easily north of $50K. Most of the cost is labor, which is $0 if you do it yourself. Some of the projects are much easier than others. If you want to fall down a rabbit hole, look in the kit car and hot rod categories; lots of affordable and small builds in there. The Buick Riviera in La La Land is more of a resto-mod cruiser project, but the small/retro itch is exactly what the kit car category scratches. The first step is to find a forum where people are building the car you like, and start following related build threads. That's the majority of my social media intake these days.
I finally decided to put together a Sonos controller with the navigation I wanted and SMAPI servers for the live music archive, and all the grateful dead and phish shows. Thanks Claude! A PWA with tailscale and I have a controller that does what I want and works at home on an S1 system and at the beach on an S2 - seamlessly. Better than the "real" thing as far as I can tell.
I am working on this Review Flow. An extention for Cursor / VScode to enable IDE as first class for code reviews.
It came from a frustration that I needed to switch between the browser and the IDE to navigate through the code and leaving comments on Gitlab at the company.
So I thought it could useful to create something and let it be accessible to the public as open source.
I’ve been exploring what sort of agentic tooling to write for creative coding and realtime VFX. My second iteration just got released earlier this week (also open source): https://sxp.studio/apps/subz
If you’re open to the idea of composing code blocks and ideas, plus some generative UI exploration, feel free to join!
I am building https://nexaflow.com - a customer support AI agent with built-in modules so small businesses need not buy 4-5 services to run a business. We ship with CRM, Ticketing, Appointment/Scheduler, Booking management system (for Small clinics, etc). Nexaflow agents can answer (and take action on) customer queries coming from Whatsapp, Email, Web (widget) and more.
Java Server Side Rendering Web Framework -- zero external runtime dependencies outside the web server layer -- https://github.com/vadimv/server-components
The idea is to provide complete Java-centric modern web UI stack for building internal tools and admin panels.
Building a rootless, namespace powered (deeply stretching the definition of a container), on demand application workspace.
- Each component in a mini app in a heavily locked down container
- Components are deployed and built in a web workspace, in the same workspace you can open a terminal and use your favourite coding agent to work on component code (each terminal is itself heavily sandboxes, has rw access only to the edited component code and users home dir)
- Everything comes with heavy rbac and minimum permissions
- Oh so much more
Explaining this well is hard, much like explaining to someone what Kubernetes or AWS does. This is at a level of what a sophisticated company infrastructure team would run, just as a workspace you can deploy for yourself easily and agents just build within that framework (I’m a cofounder of a infra/compute/datacenter startup and intimately familiar with this kind of complexity)
The main thesis is that Claw-style agents still feel like school projects, and that in the agentic era apps on demand will be more of a thing, and that the current systems weren’t built to deal with a whole new app built every few minutes.
Everyone who plays D&D has experienced the moment where they forget key details about the collective story they’re building. From ‘hey it’s been a month, where are we?’ to ‘wait who was this crazy npc again?’, ai is excellent at transcribing, notetaking and building a knowledge graph of your fantasy world.
I’m still building mostly for myself by adding a ton of features I know my friends would want, but also think there’s some ‘there’ there.
The idea is simple: let Loracle record your sessions on discord or upload the raw audio of your sessions, then get a rich personal wiki and session notes you can interact with.
If you’re mid-campaign you can also upload session notes from plain text and it bootstraps a campaign wiki. Then future audio based sessions have a good base of npcs, quests, characters, etc to build off of.
At this stage I’d love feedback more than anything else. Happy to comp a lot of usage to HNers in return for some reports on how well it’s serving you. Email admin@loracle.app for anything and everything.
I've been working with coding agents for a few years and became increasingly frustrated by the way it pushes you towards a solution. So I built rubberduck (https://userubberduck.com/) - a way to control exactly what solution the agent ends up creating by mimicking a design conversation with a competent colleague where the agent explores the solution space together and forces you to make decisions. The final output is a consolidated design document of all the decisions you made. At least that was how it began. I've since built an implementation plan step where it figures out how to translate the design to code and execution where it actually builds it. All of this happens in a properly isolated environment (using gVisor under the hood). There are more features I want to build so on it goes I suppose.
I’m working on https://main-duck.com/ which simplifies converting your code to mcp. I plan to make this easy to integrate into CI so mcps can be updated easily. It’s hosted remotely and I’m very excited about where it’ll go.
I'm working on a collaborative post-apocalyptic fitness RPG. I wanted to build a game that lets you take over the real world, gets you off the couch, and has only positive multiplayer engagement. If you find or invite another player nearby, all your actions with them benefit you both.
It's for iPhone, and for the best experience, Apple Watch. It's very early, playable via TestFlight, and I would love feedback! There's a TestFlight link at: https://reverdure.yourstrategy.co
My original idea for this was to compile an Ansible-like playbook to a binary. I made a POC for it around 2020, and then it sat on the shelf. More recently I picked it up again following a more Terraform-like model. It compiles IaC to a binary with all dependencies included, standardized CLI options, autogenerated configs, optional visualization in the browser, and lots of other features.
To people who say just use Terraform: I do, a lot. But it still bothers me enough to try building something different.
I am building https://EasyAnalytica.com - single place for all your dashboards. It generates dashboards automatically from data without using ai. It supports getting data from google sheets, api's, url's etc. I have recently added support for gsc as data source and i plan to continue adding more in coming weeks.
Working on full stack prototyping agents that own their own Aws account (zero deploy friction). Think speed of lovable/ base44 with power of Aws services
Building a new Smalltalk VM from scratch that better utilizes modern hardware (full multicore support) and a web-based system browser so I can develop with it remotely.
Working on https://razzify.in - Learn hacking using CTF challenges and get hired.
https://securepilot.in - Indias first cybersecurity incident management platform for individuals.
Still working on https://compears.shop we’ve added some new features to help people shop in the EU for cheap. I’m hoping we get to expand this to more EU countries
I'm doing a personal research project into the technical maturity of ccTLDs. So far I've mostly been working with easily accessible public information, which I'm almost ready to publish, but the next phase is going to be trying to identify markers of stack complexity (provisioning etc) which is going to be tricky.
I'd love to hear from anyone else doing work in this area!
Also finally closed the first real customer on it recently!
I want to get through a large chunk of the open issues the next few weeks and then spend some time building agentic capabilities for it.
I believe a central place to configure database access for your dev team without having to share passwords and with sensible review policies should also help e.g. if claude needs to access production data to validate a premise.
Still have to figure out the right UX though not sure the agent should have the exact same review requirements that a human does. Maybe it needs to be configurable separately
I am playing around with creating a public domain repository for ebooks. https://babelnexus.com There are a few differences. It uses core collection theory and is selective. The name comes from the short story The Library of Babel by Jorge Luis Borges. Borges used Hexagonal Galleries for his library. I realized you could put anything into hexagonal galleries. It did not have to be books composed of random letters. I also saw that you could use different levels to group kinds of knowledge using the spiral staircase concept. I have added other concepts like reading trails and cortex maps. I learned that the hexagonal concept of Borges library matches with knowledge graphs with both nodes and edges. There is a lot of experimentation in what I am doing. It is an art project, a bit of philosophizing, a bit on the public domain and many other things.
So, I built a local Mac utility that runs in the menubar to give at-a-glance visibility into live network and application issues. It's free (for typical uses), battery-efficient, and gives fast and reliable answers.
I’m working on Envelope. https://envelopebudgeting.com It’s a budgeting app that comes with a built in checking account and debit cards. Because your budget can actually decline card transactions it’s a very effective system for stopping overspending.
I’m currently migrating the codebase to Swift 6 and dealing with the new concurrency system.
Note: this involves blockchain VMs. If that's a dealbreaker, feel free to skip. I get it.
I've spent 8 years working on RISC-V VMs for blockchains, recently also contributing to ZK VMs. Modern blockchain VMs are drastically more powerful, and I'm curious how far we can push them. I started porting real game logic to blockchain VMs, running game loop, physics simulation, collision detection, etc., on blockchain VMs. So far I have:
Source is available for 2 of the 3, I need to clean up the OHOL one.
Some context: CKB-VM [1] is a RISC-V virtual machine I designed for Nervos starting in 2018. Jolt ZK VM [2] is a zero-knowledge virtual machine developed by a16z. Both execute RISC-V code, but due to different design, Jolt ZK VM is a much faster CPU than CKB-VM.
Technically this is a fun challenge. Many techniques I used resemble game development tricks from the 90s on game consoles: fixed point math, banked memory in ROMs, aggressively inlining tricks, etc. I want to push to see where the ceiling is. Right now I'm trying to get a Godot [3] + JoltPhysics [4] game loop running on Jolt ZK VM.
Happy to answer questions about the VM internals, the porting process, or anything in general.
It's a calculator for what an AI feature costs to serve. Cost per request, cost per month, which part of the bill is eating you (output tokens, usually). No signup, all the math is on the page. Any feedback is welcome.
I got sick of choosing between the efficiency of working in a terminal and the magic powers of using AI (and of copy-pasting between the two). So I created a hybrid: Terminai is a transparent wrapper for any terminal that provides on-demand access to a TUI coding agent of your choice just a hotkey away (with built-in MCP and CLI that gives the AI access to your terminal).
A text-based song format for generating music. I wanted to be able to create a song entirely using text, so I created a TOML-based format for doing so, and gave it most of the features you would find in a DAW. Since the format can be described in a SKILL file, AI can be used to write a song in this format, which can then be converted to audio.
This month has mostly been personal website. Serious warning - style is an HN ripoff atm, forgive me in advance. Will change in the future to something original or minimal.
Project I've got in progress is a migration of the old DIKU mud engine from C to Rust and making a Moog Model D synth recreation in rust with a JS wrapper.
The slime art is nice. I watched it for a long time. It's neat how you can open any frame up as an image. The controls in the description didn't work though.
Still a small plattform for groups of gamers to share their library with each other and suggest and vote on games for a game night.
I'm planning on a group finder feature where you can publicly search for others to play with you, currently it's more angled at existing groups.
A competitive word guessing game, play against family/colleagues etc, it tracks your solves and some other fun metrics. Totally free, no ads or other crap. No login needed to play.
No monetisation needed. It's for people to enjoy and to be a real world project I can use to do agent experiments with from code through to devops type stuff.
Rewriting the region drawing code in my LisaGUI project so it does per-word bitwise operations instead of per-pixel calculations. I'm using Claude to help plan and debug it, but I'm being careful to review all its outputs and make sure I fully understand what it's suggesting and why. I don't want to lose all my neurons to this thing...
I am working on 2 football game websites, one for world cup https://7-0worldcup.org/,and the other for Top 5 leagues https://38-0.one/
Developing game is easy now, but it is really hard for promotion.
I'm working on MedAngle, the world's first Agentic AI Super App for medical and dental school. You can think of it as literally everything one would need from day one of admission till graduation day as a doctor.
I myself am the first medical doctor and full stack engineer in the history of my country (250 million), graduated as a doctor at age 25, and we have over 100+ users [all of which are medical/dental students and doctors], 10s of billions of seconds studying smarter, hundreds of millions of questions solved, and more.
Our Super App has subsystems including MedGPT, MedAgent, Spaci (our own take on spaced repetition) and much more.
We're bootstrapped, and continuing to scale. If you are in medical school or know someone who is, please reach out!
I'm working on the finishing touches for a big new "Event Filters" feature for my Shopify app, Stages (https://getstages.com). The feature will let users set up rules to decide which orders should be imported into the app based on certain criteria like Shopify product names, collection names, order value, and so on. Users have been asking for it forever, and I'm planning on publishing it this week!
I'm also working on an update to ShopifySharp, the .NET package I maintain for Shopify's graphql and rest APIs. I need to regenerate the graphql types and the fluent query builders for the July 2026 API version that was just released, and I'm planning on some extra QoL improvements that I've run into while using the package over the last couple of months. I particularly want to add some F# QoL features, since I wrote the package in C# but use F# in all my personal projects. (https://github.com/nozzlegear/shopifysharp)
This does review aggregation for businesses, and then a bunch of tools to help you gain insights, respond to reviews, and get more reviews. I just hired my first Sales/Marketing person to scale.
I will create coupon codes for anyone interested! Email is in my bio
I'm not a big fan of the encroachment of AI into Adobe's apps, so I'm using AI to build a replacement for those apps (a small web-based photo organizer and editor, just the tiny subset of the Lightroom features I need for my workflow)
What if your web apps e2e tests ran in production through actual user sessions? Know exactly what browser session cohorts are having issues. Open source, https://github.com/Faultsense/faultsense-agent
Working on Gaming Couch, a web-based local multiplayer party game platform. It's like a lovechild of Jackbox and Mario Party: https://gamingcouch.com
Just before the weekend I shipped a new mini-game called Pop It: Desert Island (https://gamingcouch.com/blog/pop-it-desert-island-launch). Launch went well: ~3,800 players from 56 countries over the weekend, and it immediately became the most played game on the platform.
It's a battle royale with an ocean/beach themed world, taking inspiration from Roblox, Mario Kart and others. The whole game is built in JavaScript (three.js for the 3D world) using a JS SDK I've been working on. It doubled as a test drive of the same SDK I want to launch for third-party developers, so anyone can build and ship a simple, fun multiplayer party game for the platform, ideally in a single weekend.
If you're a game dev, or aspiring to be one, and want to develop and ship your own party game check out this page https://gamingcouch.com/developers
The TL;DR of Gaming Couch:
- Free Early Access with +20 competitive mini-games.
- Players use their phones as controllers (gamepads work too).
- Completely web-based, no downloads or installs needed.
- Every game supports up to 8 players and is action-based, with quick ~1 minute rounds to keep a good pace. No language-based trivia or asynchronous (turn based) games.
I went on a side quest to strip out ProseMirror and markdown-it and implement a custom stack instead. I open sourced both the parser and editor (https://saturn9.studio/technology/):
Building Critical Infrastructure protection software that helps security teams create real grounded processes that don’t live in spreadsheets and slide decks. https://cabreza.com
Most critical infrastructure orgs don’t have the budget to hire consultants, and even if they do, the deliverable is a deck, or a spreadsheet, or a PDF. We want to help any org of any size create a security regimen outside of these stale and disparate docs. For FREE.
Plus we have additional tools that we are building on top of the free software that will help in other areas besides policies and procedures. Like OSINT of any orgs operational and physical footprints.
This is basically my version of "what all could you throw into Postgres?"
My problem with vibe coding/LLM assisted engineering is that it's hard to get the basic stuff that is independent of the application itself, correct, so I just use this and make sure everything I build has some consistency.
You can pop this in and use it as the base for your app and add login, permissions, etc. quite cleanly.
I just launched my digital media shelf on my personal website, a catalog of my favorite books, movies, records, podcasts, and more. Lots of fun to build despite some false starts and fits:
Created a react-doctor style cli to deterministically scan for misconfigurations, missing observability, and security posture.
Now working on extending it so vibe-coders can secure their apps too!
Underpinning my current app is an e2ee local-first sync engine, basically it is a traditional client-server sync (encrypted logs + snapshots sequenced with integers). It sends bundles of Loro CRDT operations. I wrapped the client side in WASM to power the web app and the CLI and have started a swift wrapper to port to native iOS. Bundle size is 3MB/1.2MB g-zipped so pretty happy with it. I've realised that web encryption is kind of bs (at least not as "WE CAN NEVER ACCESS YOUR DATA" as some vendors state) if someone else is distributing the app.
Over the last week I have done a lot of performance work & data remodeling - CRDTs are interesting because you can let data fall through the gaps if you're not careful.
I have ADHD, and my calendar is a graveyard of things that were totally fine right up until they were on fire.
So about to release an iOS app that sends me early notifications about what to actually prepare, or do.
Best examples so far: on my last trip it pinged me the night before with a packing list based on the weather at my destination. Also reminding me to book a table for a dinner planned.
I'm working on better UI for my app AutoPTT [1]. It's probably going to look somewhat similar to Discord's settings, except I won't be using Electron. I refuse to use bloated stuff like that, so I'm going to keep using a pure C UI library [2].
Obviously this is going to take a bit more work but at least the resource usage will stay low, which I consider quite important. Especially since gamers are a large portion of the user base.
I'm using Gemma 31b to build tools for myself to optimize my WoW TBC play to an absurdist level. I'm hoping to have world top 10 parses across the board in a few months, loot gods willing.
It’s an AI-powered mock technical interviewing platform, for system design and coding.
I’m also working now on behavioral mocks, with a coach feature!
I’ve been working on it on and off for a year, but started spending significant time in the last few months.
I know everyone’s burnt out on LLM products, but I think it’s nice for this kind of prep since you can do it on demand and in an environment it’s safe to fail as much as you need without judgement so you can actually learn.
It’s early and free if anyone is interested in trying it out (at least while I can afford to serve it for free)
I continue to work on version 2 of a product that’s been shipping for the last couple of years. I’m not linking to it, because the last thing it needs, is a bunch of folks registering single-use accounts, only to find it doesn’t interest them, but we need to wait a year, to delete the resource hog they registered.
Version 2 is a significant upgrade, and is a bottom-to-top rewrite of both the backend server, and frontend app.
I’ve been using an LLM extensively, and it’s been a huge help. I have, however, also run into its limitations.
Taking a bit of a detour with self-hosting the language, now that the syntactic surface, standard library, and initial dependency strategy are on a decent footing.
With any luck, by the end of the week, I'll start prepping for a 0.0.1 release.
Scaling Zigpoll[0] to 2M ARR as a solo founder (currently at 1.5 ARR). Each year you double ARR for a business it comes with a whole new set of challenges which are layered on top of the changes in the tech landscape.
Fortunately I think I've been bailed out by agentic coding the last couple months from a product perspective but I think the major gains so far have been due to marketing and exploring alternative growth channels. Even so, keeping momentum is never a given and requires constant output from all angles! Onward...
- https://banksia.bio: I suspect there is a market for private consumer whole genome sequencing services. Think "Mullvad vpn" of sequencing - I shouldn't have to know the identity of the person I am sequencing, and they can be identified with a client number not tied to their PII.
- lazyslurm: A TUI tool for managing/viewing slurm / HPC setups. Similar to lazygit or lazydocker (https://github.com/hill/lazyslurm)
I'm building a family game server that will host web-based games on my local network (although I'm thinking about using something like Cloudflare Tunnel to make it available on the internet).
The first game I'm building is the card game Phase 10, and I'm done with phases 1-7. After that, I'd like to build Carcassonne, and maybe Jeopardy.
Rebuilding my long ERP-like project to become more like a "business engine" to become a proper ERP backend (so it can cover most business scenarios and is multi-company, branch, currency, etc).
Have now the core done and working on a MVP UI to validate it.
One of the things I always wish to do properly was to model currency and unit of measure in full as core types, plus truly trace everything related to the business transaction from production to beyond the sale.
Looking into a persistent workflow engine like `temporal` now...
P.D: I'm debating if open source or not, in light of the AI-pocalypse...
Did pretty well, only took a day or so. I first had it inventory every MUST, SHOULD, and MAY in the spec, and then let it rip. I did guide it quite a bit to get what I wanted, but at the end I’m pretty happy with it as a first draft.
Helped me learn the spec and will be helpful to hone my dotnet AEP server, and aepbase.
There already existed an aep e2e validator which does a similar thing, but this is more thorough and generates a nice report. It will tell you not just whether your API follows the spec, but also what parts of the spec it does not implement.
I usually work on my programming language lone lisp on my free time but I've been feeling burned out lately.
So I started a new side project: decompilation of my cherished childhood video games. Many Mega Man games, starting with Mega Man Battle Network 2.
I just finished polishing and verifying the early initialization routines, and have already traced various parts of the game's engine. I was surprised to discover that it was a huge state machine of sorts. I want to focus on reverse engineering the saving system so I can write a save editor, and the music system so I can listen to the music.
I've been helping people achieve their reading goals by hosting workshops at libraries and helping adults become more intentional about their reading goals and how to achieve them.
I created a setapp alternative at https://getapps.cafe. 40 local-first apps and counting and yes I use claude code to help building all these apps (and I do read the code). It is so much easier now to start and create small, self contained apps and I do the future is local/privacy by default apps
I needed to get customers for Hyperclast [1], but I kept procrastinating on the go-to-market tasks. I'd rather be building, you know! So I created https://tractionbeast.com/ as a tool for myself. It gives me bite-sized tasks every day. I just review and do them. This completely removes the inertia for me. My other founder-friends like it too so I turned it into a product.
If you're an early stage b2b founder, I'd love to hear your feedback about TractionBeast.
I am making it easy to embed coding mode AI agents into SaaS applications. We have a WinterTC compatible custom JS runtime that lets the agents write code to accomplish tasks and a SDK to embed agents into your SaaS apps. We help you write skill files on our coding agent against your API and use our frontend SDK to embed the agent into your app a.la Intercom. See https://uraiai.com/
I’m working on building AI-backed sms phone numbers for lead generation campaigns needing 24/7 or multilingual support. Less friction than downloading apps or interfacing with chat bots, and just as powerful.
I think I am your target customer. I own a national health care franchise and want private AI. What is unclear to me from your site that I view as a gating item is do you source, install and configure the hardware or deploy your platform on ours. Or both?
I’ve been working on Hype Doc. I built it for myself and hope others find it useful. I decided to build the mobile apps too and that process is way more work than I expected. It’s been fun though to dive into Rails 8 in the process.
As a kibbutznik myself i built it to govern every possible community for all flavor and size with the inspiration of my experience in a tight democratic way of living ,I have given a lot of thought into it but it remained just an idea, i am a developer and my marketing skills are none existing and time is limited so no one use it. glad you liked it :)
With all the supply chain attacks on OSS ecosystems targeting developers, PMG is a practical protection using a combination of threat intel, policy and sandbox.
It’s a package firewall on the terminal really. It has been surprisingly effective against most of the recent attacks.
Been building a open-source technical interview platform. Trying to keep the existing ideas of async coding assessments + live programming interviews, but want to add features for the new interview formats I see of take-home projects + AI coding agent interviews
A News Platform aggregator collecting sources of information across the internet (socials, newswires, etc.) and trying to push context to humans in a more digestible form. We are also experimenting with defining lineage of information using AI to help people try to piece the puzzle together as information flows in.
Exploring highly interactive instrument (piano) practice to see if AI can help students practice better. Full duplex voice agent alongside your practice session. Also exploring live AI jamming partner to practice playing with others.
Most recently, adding SID support, and adding timing information to the emulated formats that don’t have any tagged song duration (e.g., converting NSF to NSFE). This means playing the songs one by one and watching for repeated sequences of writes to the sound chip registers.
This month I've been working on the free desktop version which is available as of today but probably carries a few too many bugs to not be worth promoting just yet.
This is an open source tool to run background coding agents + dev environment in isolated VMs. So far it has allowed me to migrate a majority of long running coding sessions to my homelab to run remotely. I can also run multiple in parallel without worrying about race conditions or my host machine breaking.
I'm working on leveraging NLP and LLM techniques to create a geometry over the discrete space of Ethereum transaction execution structure. (sorry... it's a bit of a mouthful)
Scrolless, a Safari extension that keeps all the human parts of social media (search, DMs, stories, posts from friends) while removing all the algorithmic garbage designed to suck up your attention.
A minimal, immutable Unix-based OS with built-in attestation and runtime integrity for deploying server applications in microVMs - https://www.gingercybersecurity.com/
I'm working on so101-nexus, an open-source sim-to-real stack for the SO-100/SO-101 robot arms where you can record teleop demos, behavior-clone a policy, then fine-tune with RL. The goal is to be very compatible with Gymnasium, MuJoCo, and LeRobot.
Sharable, real-time synced maps, Google Docs for maps basically.
I think the coolest part is the import feature where you can paste a link to a video or article and it pulls out places and enriches them with images and a description. You can also write your own notes, vote on places to go with friends, and apply colors. Right now I am working on user acquisition and experimenting with different marketing approaches.
A daemon-focused CLI driven music player for GNU/Linux.
I recently got it working with playerctl by exposing it to dbus using zbus, great fun.
https://git.2137697.xyz/salmon/rsplayer
I struggle with terminology so I made a little Gnome utility for easier LLM-based terminology lookups from a highlighted word/term + contextual screenshot. So far it's working pretty well, kinda like a better version of the Mac OS or Kindle ones.
I've been building WhyNotLog to answer tricky questions using statistics. Example questions include "what gives my dog allergies?" or "what affects my sleep?".
Available at https://whynotlog.com and promo code HACKERNEWS gives access to the pro plan for six months.
This month I worked on my own AI agent written in POSIX shell. It's been surprisingly useful for debugging command line problems on an old laptop running linux, like fixing an apt problem.
Unfortunately due to the way GitHub defaults to creating prs in the parent fork, I have accidentally created a few invalid prs in asahi before I was ready, and now am banned from creating a good upstream one
Looking to experience life outside of software, but I don't know exactly what. In short, current filters are:
high total customer face to face time//
high face to face time per customer//
probably not in sales
as these are too abstract to map cleanly to traditional job board filters I’m scraping indeed and using deepseek to classify jobs according to this criteria, with an aim to discover really good jobs and then put a lot of effort into each of those jobs, like reaching out to hiring teams directly etc. works alright but worried coverage is an issue.
ps- can any one recommend a service or product that does this already? i should be able to set a city and then write my own filters like "this job involves dressing up like a crocodile" or "this job requires ballet dancer experience" and have each job posted in my city get assessed. maybe i get an email each day of matched and not matched jobs. i have tried to search myself but given there is so so so much slop in this space i find it very hard going. and most products do this just very poorly...
I follow a bunch of gaming rss feeds just to keep up with what’s new in the industry. Figured I’d take those and turn them into a news aggregator to put them all into one place. Threw in some game deals/affiliate to pay the web hosting bills (hasn’t paid for anything yet, lol).
I am building Bloomberry (https://bloomberry.com), an alternative to tools like BuiltWith/Wappalyzer to provide sales signals when companies subscribe or churn from over 1600 B2B tech products. Think backend/backoffice tools like Hubspot CRM, or Netsuite, or Microsoft 365, rather than frontend technologies like Wordpress or React.
I'm using AI to build a project to teach me SQL.
I use claude code to build the lessons, and then I complete them myself. I've done this for a few topics already, and I think it's one of the most amazing things you can do with LLMs.
apt-cacher-ultra: To help reduce the impact of future DDoSes of Ubuntu. Just released 1.0 yesterday after working on it a couple months.
As that DDoS was going on I realized that some of our dev and staging processes were impacted by it, and that apt-cacher-ng was doing nothing to help us.
apt-cacher-ultra snapshots the repo meta-data after verifying it, and only promotes it if the metadata all checks out. Additionally, it can optionally keep a list of "hot" packages, and can include those in the snapshot calculation.
Additionally, apt-cacher-ng would regularly choke and require some handholding. I'm hoping -ultra resolves that as well.
https://timelinetranslate.com
Translate any video or subtitle file into any other language. Launched yesterday and geared towards video editors with a DaVinci Resolve plugin. Delivers more control and ownership of the editorial process compared to other automated dubbing or subtitling.
I am working on a reddit lead generator that pings you when someone wants a product like yours in real time, and It does so only when the intent is high.
Was using this only for my self, but i think it might be interesting for other people as well.
Had the same experience with upwork, feels like the door has closed on easy api access to big site data, ironically funneling people's money to proxies and other scrape helpers instead of their own api.
Yeah, perhaps its due to noone wants LLMs trained on their data for free. I don't know, at least for reddit there are still ways to get the data for free.
I’m working on Ovio (https://ovio.au), a record-keeping app for Australian freelancers/sole traders/small businesses.
The current version is deliberately narrow: send receipts by email/whatsapp; import bank transactions from CSV; and Ovio extracts the details and auto reconciles. From there you can check a BAS/GST-style summary and export organised records for an accountant.
It's been quite fun building this as this solves my exact problem, but trying to find an audience for a product is a completely different game
For the life of me, I could never get electronics. I used to love the idea of me coming up with electronic circuit designs, but the arcane art of electronics never really clicked for me because I just couldn't intuitively grasp the maths no matter which book I read (AoE, I'm looking at you). But then it hit me, I don't need maths, I just need a formal language to represent the circuits. So over the past few weeks, I worked on a code your own spice (the electronic simulator). So now, for the first time in history, I finally understand how circuits work and how they are designed. And I did this all by coding circuits in python and making my own functional spice (which used to seem impossible at one point, it's surprising how easy it is though).
building https://shellular.dev, an app that let's you use your dev env from anywhere - your agents (Claude Code, Codex. OpenCode, Pi etc.), persistent terminals, local repos and code editor, in-app browser to remotely access localhost:<any-port> and js console for debugging.
7stems.net: a Spanish verb conjugator and method for learning Spanish verb conjugation, where irregular verbs are just verbs with more than one stem. Also just self-published a book.
I ran into the same performance issues when reviewing Next.js apps, so I made a tool that scans Next.js sites and tells you what's slow. It's basically a performance tool that works best with Next.js apps, and highlights things like slow LCP, heavy JavaScript, and third-party impact and gives you suggestions and prioritizes them. Here is the link if anyone wants to check it out:
This month https://thingstohave.app, my calm and flexible wishlist app, reached a state I can call "feature complete". This iteration took two years of occasional work, so it's a big milestone for me. (I've posted updates on this app in previous threads)
Since the last update, I released everything that had been in testing since April, like gallery view, custom avatars, birthdays and, most importantly – autofill from link.
Now I'm preparing for a big launch – working on the landing page, SEO and onboarding experience. Here's what I've done so far:
1. I updated the landing page to actually tell users about the app and look presentable. I already see a big improvement in conversion
2. I added SEO crap to the landing page. This is painful for me, but sadly that's how Google Search works (it doesn't). It's paying off, too
3. I overhauled the onboarding experience, to make it smoother for new users
Two more features are still in testing; I plan to ship them before the release, but currently i'm not completely happy about them.
Using UEFI SecureBoot + vTPM for cloud root-of-trust, a stack to prove what's released on github/gitlab is what's actually running on GCP/EC2 (and soon Azure & AliYun).
I was annoyed that so many companies in the Web3 space would do the on-chain theater of verified contracts and "audits" then 99% of their infra would be deployed on EC2 (or god forbid Vercel) in full un-ironic "Trust Me Bro" mode.
It's a different trust model from SGX/TDX, more pragmatic and hopefully easier/cheaper. Currently polishing off "Docker to verifiable cloud VM" stuff, and then gVisor support next.
A clojure / fennel dsl for generating pure data patches, looking to make a small drum machine in love2d and being able to live update the internal patches would be fun.
Code World Models in Simultaneous Move settings like Capital Markets. DeepMind's CWM approach relies on standard MCTS/IS-MCTS, which assumes a single active player at each node.
This doesn't work in simultaneous-move settings like Orbit Wars (or order-book markets), converging to an exploitable pure strategy rather than a Nash equilibrium.
LeCun's JEPA, by contrast, is a learned neural world model, which lacks the determinism, speed, and debuggability of a code-based simulator. Thus, it can drift or predict illegal states, and you can't inspect why it made a prediction the way you can trace a Python function.
TL;DR: The benefit is better auditability and easier RL-like training.
The SM-MCTS extension fixes the first problem (decoupled UCB per player approximates Nash equilibrium instead of a pure strategy) while keeping the second advantage intact (a deterministic, inspectable code simulator).
To investigate the use of LLMs to weed out low value posts and comments, mostly. If a lot of submitted content is by agents, then let them play but figure out how to not overload the humans. Also, how to enable assisted discussion without walls of text.
I've been working on an LLM "harness" called Logbook[0] for fun with Codex.
The core idea was that I've always been a lousy notetaker, even going back to my school days years ago. I'm great at one-off and one-liner notes and occasionally more in-depth notes, but tend to not flesh them out fully enough to make them worth re-visiting.
This has been a struggle even as an engineer sitting in meetings or trying to absorb new information when starting a new job and ramping up.
Logbook is meant to use an interaction paradigm we as engineers are using very often these days: it's a terminal UI in the vein of Claude Code, OpenAI Codex, etc.
It's targeted at the entry of free-flowing thoughts but you can also write longer notes by launching your default shell editor from within the tool.
Each note is saved as markdown with some metadata and that metadata is then saved to a local SQLite DB.
For the LLM side, the tool extracts useful metadata from those notes and then performs some local ranking/categorization. It then has the ability to send a note or some metadata to a provider of your choosing (it's straightforward to use OpenAI or something more broad and customizable like OpenRouter) for further enrichment or filtering.
A couple examples of the currently implemented slash-commands: `/related` can be used to find related notes; say you've been scribbling down notes about OAuth or MCP servers and want to gather up the most relevant notes to one of those topics. Or you can use a `/gaps` command that'll help you find things you've taken notes about but without properly defining or providing context around them (i.e. you mention ID-JAG for OAuth but never actually say what ID-JAG is, this command will tell you this so you have a chance to review what you previously wrote and can then define exactly what that keyword is about).
It's still very much a work in progress. It's not meant to be a full-fledged note-taking app a la Obsidian or anything like that. I've just always preferred taking notes in markdown or plain text and this is a great way to continue doing that while also making enrichment of the notes pretty simple.
You may ask "why not just use agent memories?" I don't really like the idea of tightly coupling notes with codebases or agents and I don't find the current UX very intuitive at least for the way I prefer to take notes.
It really is useful.. If you add your favorite places... it will give you pretty good suggestions using the ai wrapper when you travel and it is good at giving joint recommendations for you and your friends.
In my 20 something experience of software development, it is totally ok if you don't work on anything so I don't work on something. If there is a possibility that your work will be something useful plus you will benefit from that, you definitely have enough time to do that in couple of coffee tea drinking times. Europe show off by their sidewalks and street signs. Computer is a little too lux for a human.
I've found Astro to be an amazing framework for simple, performant websites. It stays really close to basic HTML and CSS while adding useful features such as scoped components, layouts, and easy Markdown blog integration.
So I have been using it to build websites. But many things keep repeating with every website I build, so I began working on this project to create a base that I can use for every new web project.
When it is far enough along, I will use it for the landing page of the app I'm working on: a customizable solution for self-tracking including habits, health and journaling, or whatever else you need: https://dailyselftrack.com/
After more than 400 days of traveling around Korea, Macau, Mainland China, Japan and Australia, I'm now returning to Germany / Europe looking for work. I wrote about that in my monthly mail-letter: https://bryanhogan.com/follow
Search is currently provided by the Radio Browser API, but I'm now building my own station API with proper metadata and thumbnail coverage. A station discovery page with most played stations is also in the making.
I've had an idea for a different type of free & open search engine for the last 15 years. I ended up pursing other ideas instead over the years.
Last month however I decided to go back to the idea and give it a shot. Right now I'm in the process of scraping and building a huge index. The technical challenges have been plenty. But I should be ready to publish an alpha version by end of month or so.
i make the microsoft word but less sucks, and there is scientific calculator integrated and also ai on it too, available on linux (stable) and windous (unstable).
I'm building Voxoria (https://voxoria.ai), it tracks whether B2B brands get mentioned when people ask ChatGPT/Perplexity/Gemini instead of Googling.
Ask the same engine the same question twice and you get different answers, different citations, sometimes a different opinion of your brand, so figuring out how best to present this has been a fun product problem to solve.
It also tries not to be yet another dashboard: instead of just analytics, an agent turns the findings into a ranked list of "ship this fix" todo items.
Curious, how fast the AI providers re-index a page after you make a change? Do you see the results in the next model update, or do they try to use more realtime data by making their agent fetching the website every time?
I'm creating my own language using AI.
About half of the C backend I wrote myself, and I'm putting in the syntax I want and the things I want to create.
I'm not sure if it will be finished.
https://github.com/srtdog64/PergyraLang
I'm working on Hiring Method (https://hiring-method.com). After ~2 years of development and two exhausting pivots, v1 is finally live.
I see a lot of new (and, to be frank, a lot of mature ones) HR tools are just wrapping Chatgpt around resumes (almost like "OK, now match this resume against this job posting and tell me if applicant fits"), which introduces a massive bias/inference problem.
I decided to build the exact opposite – a deterministic, math-driven fitness engine. It extracts structured scorecards from both CVs and job requirements and mathematically matches them, so you can actually review the exact reasoning behind why a candidate scored a, say, 85%. This fitness value is specified at every interview step – as applicant goes through an interview process their scorecard is updated at all steps.
If anyone here builds in the HR space, I’d love your feedback.
I had problems waking up and was looking for an alarm clock on Amazon. But I could only find analog clocks with the famously unreliably moments, and digital clocks which were overpriced and looked ugly. This feels like a real gap in the market, so I'm working on making my own alarm clock. It's a simple enough project but includes PCB design and modelling the case, etc, which I don't have experience in.
I tend to print a lot of stuff to read while disconnected. This is a tool to help squeeze as much content onto a printed page as possible instead of printing 4 or more pages per sheet.
A good use of Claude slop I'd argue. Currently trying to figure out how to set up the site so that an LLM tasked with printing content through it can figure out how to use it in the best way.
Telemetry tooling for local Claude/Codex usage so I can analyze old sessions and fill tooling gaps, make sure I'm using the right models for various tasks, update my processes, etc.
I've also replaced Linear with a local sqlite-backed tool, added tooling to speed up code nav, and am building "no-slop", a tool for enforcing architectural guidelines on vibe-coded projects.
I'm having fun writing another agent harness nobody uses for real (not even me). As a side effect, I got an actor library in typescript to do it: https://github.com/muromec/posipaki .
After some time I figured the best use of AI is to produce even more AI-related slop and spend my occasional 2 dollars on the deep seek model to do it.
Models are fun when given a stable identity and made aware of it.
So I am building https://buyvds.net with a global visual interface which has a list of around I think 249 vps providers over 60 countries combining up to 863 links (one vps provider can provide vps in multiple countries)
It uses DuckDB to expose a sql query interface in the website itself because I wanted to give the freedom to just do something interesting with the data.
My friend John had an idea which I really liked so I added "john mode" which shows what he was suggesting :-D
I think that Hackernews might like it but honestly, I have probably just made it out for myself and also as something to just share casually with folks on hackernews and other websites and hopefully I am able to help people and myself in some way with this website.
Open to some feedback as usual (for mostly all my projects really) and thanks for reading and have a good day dear reader and hey perhaps give my website a try!
building a 90s style point and click 2d game called AshNOak that generates varied stories with 3 characters. Story beats are managed using opensource LLMs. still a WIP.
I've been climbing for a decade, but over the past 3 years I've put on a bunch of weight due to work and certain life events. But I want to change that.
I know what motivates me: seeing progress. The feedback loop of "do X, see Y gain" is what keeps me going.
So I started building an integrated dashboard that can aggregate data from multiple systems:
- My digital scale
- Apple Watch (sleep + running performance)
- Beastmaker Motherboard, which is an electronic board that you attach a hangboard to and it shows you various stats like how much force you're applying
The idea is that every morning I'll open the dashboard and be able to see exactly how much progress I've made the previous day: weight loss, strength gain, cardio performance.
It's an interesting problem. There's essentially two parts to it: Apple Health, which aggregates data from the scale and the Apple Watch and can POST-export it hourly, and the electronic board, which sends data via BLE in real time. The destination for both of these will probably be an always-on Raspberry Pi 5, but I haven't decided yet. Then I'll have a small server app that can pull the data from the Pi and draw some fancy charts.
I've been working on a similar concept (aggregate health data from multiple sources) but on a wider scale:
1) annual bloodwork as part of my annual preventive care;
2) InBody measurements, including grip strength;
3) quality of air in my region;
4) Apple Watch but mainly for steps, sleep data and resting heart rate;
5) allergy panel or minerals/vitamins screen plus something nutrition-related along those lines (TBD).
The idea is to see trends and try to apply AI for correlating, at the first glance, completely unrelated data layers. Example how I'm thinking about this one: there's somewhat clear correlation that I sleep better when I do above average steps per day. How is my sleep quality affected if, let's say, I did above avg steps with a bad air quality at that time? (i.e. wild fires / pollen season / etc.)
I've built a Go application to ingest those data sources and currently finishing my first import use case - Apple Watch data.
I (and Claude, codex, etc) have compiled/ran wayland, X11, GNOME, KDE, and Ladybird natively on a jailbroken iPad. Hoping to release more details soon but I have a slop wiki here:
An acoustic analyzer for a sink basin in a hackerspace. It will allow for automatic detection of dishes/cups left in the sink without cameras and can be handled by an rp2040. So far looks like it has very low false positives but can only successfully detect certain materials or large masses.
- Got https://beachcomber.sh pretty much stable. Next stage is to propose to various upstreams its worth integrating.
- Custom firmware for some ikea symfonisk dials because the oem firmware on them has some pretty bad bugs. Added features like hold and turn. Getting nice smooth dial behaviour over zigbee etc is surprisingly tricky
- Built a skill evaluator tool that runs a skill through test suites and then tweaks the skill context and runs again. Its been pretty effective to be honest, almost all skills you do the first version is laughable compared to the one you get after this automated self improvement.
- A robust tmux bridge interface for claude to hook into, and then a director layer on top of that for agent orchestration tooling
- a stenographer skill that on the fly ripgrep and builds a rag on your on disk conversation history as a form of memory. Pretty effective.
- I have just started a tool that brokers woodpecker ci to openbao/vault to give a gitlab like integration for controlled secrets injection for ci.
- Been beating my head against a camera tool for a while now, finally making headway. Many ptz cameras dont support fov move, which nvrs need for ml object detection and tracking. They just have a super clunky continuous move and stop. So my tool characterises the camera with cv tools and calibrates movement curves to produce a data file that can be used by my onvif proxy to emulate the more advanced move commands.
- Various helper tools for fusion, like csv based parameterised export, and compliant magnet insert generators.
- A pipeline that consumes my content backlog, ie instagram saves, reddit saves, hn faves, etc and analyses them with local models and various algorithms steps to categorise and intuit why it was saved and what the key information is and what category it fits into for future reference etc.
- A map of my city that shows live river height data with flood map overlays, contour data, predicted overland flow etc. flooding is a regular concern but theres no great resource to know whats going on. I have about 60gb of public datasets it works with.
- A package manager for kicad library symbols and footprints, datasheets
- skills for kicad so claude can reasonably interpret the schematic and advise on problems, check against datasheets etc. surprisingly effective.
- A gcode controlled expansion board for the Carvera Air that gives you 8+8 channels of control for extraction, air assist, vacuum table, timelapse camera, etc. you only have 1 pwm pin so the protocol encodes over that.
- A novel exploration interface for vitamins that renders them in a network graph, showing relationships. When you select one it rearranges around it into a kind of valance orbit style so you can explore chains of effect. Turns out, lots and lots of things relate to magnesium.
- A comprehensive usb c pd board with 4s battery management. 3a or 8a depending on version. Trying to do proper pd in is nontrivial so this is a drop in solve.
- A new brain pcb for Kinesis Advantage Pro keyboards to give modern firmware, bluetooth etc.
- Repacked my rack UPS battery with LiFePo cells, and built an induction/resistive series battery balancer pcb for it.
- Playing around with a new debug header/connector concept thats tiny footprint and zero cost to add.
The hard part is getting things over the line, publishing and seeing if theres interest. A thing can be largely done but theres a lot of detail work polishing it up so its public ready.
Right now it copes with important open source libraries on the model of clang-format's configuration, which is a real trick given the partial elaboration you need (with backtracking). But that works.
mathlib4 is the final boss, I don't currently even have a plan without per-directory quirks files which is probably a nonstarter.
I’m working on a synthetic control arm for a heart valve trial using synthetic patients from both the heart valve registry (in the near future) and a frozen EHR encoder. It’s pretty fun exercise.
World's first LLMORPG. You craft a prompt and it goes to live in wafertown and interact with other players (I mean prompts), you can change your prompt once per day, then next day you get news about what you did there!
Super early, everything is manual rn, I'm automating stuff including sign ups, if you want to join shoot me an email!
suprasole - a pty proxy for enabling deterministic and ergonomic extensions/middleware for harnesses in an agnostic way... also working towards building an automation/scripting layer on top of harnesses via suprasole...
I've spent the last months building a videogame: Cardume [1], its a pvp game where 2 players battle using a swarm of thousands of cells. It uses Reynold's boids, Couzin flocking behaviors and diffuse fields to generate a mini ecological simulation each game. The sim is pretty well optimized, handling 12k agents at 60fps in a medium hardware machine. It also has some pretty cool visuals. Any feedback appreciated, the Store went page online this last week and I'm still working on the presentation.

Two weeks ago presented current state of KEIBIDROP at Pass The SALT 2026, and now I am planning the push for the next version 0.4.0.
KEIBIDROP: Makes remote files appear as local (it hides the network latency in order to let you open and edit a peers file without downloading it upfront or re-uploading it fully back).
For version 0.4.0 I am planning multi-user support, using UDP (QUIC) instead of TCP as the networking layer, optimization of live-edit regions of files, and to test it even more for data heavy workflows.
Here is the website: https://keibidrop.com/
And here is the github: https://github.com/KeibiSoft/KeibiDrop/
With the help of AI & LLMs I restarted working on some of my older side projects. I updated the code and did a landing page for Printable Mockups (a free, open-source drag-and-drop tool for creating device accurate wireframes and sketchpads that you can export as PDFs, print, and sketch on by hand) https://github.com/alexadam/printable-mockups I plan to add more features soon.
My wife and I continue to work on Uruky [1], a simpler Kagi alternative, based in the EU.
Last month we reached 200 monthly active accounts (we’ve passed 250 now), and last week we launched support for XMR/Monero payments via ProxyStore [2]!
You can also see in our homepage that more independent bloggers and privacy-minded people have written about us!
The main differences between Uruky and Kagi, DuckDuckGo, SearXNG, etc. are visible in the footer (right side), but one huge difference is that with Uruky, after being a paying customer for 12 months, you get copy of the source code (licensed as BUSL,into AGPLv3 in 2 years — a suggestion made here in HN)!
Uruky is paid and you can get a free 2h trial when you signup if you pass a proof-of-work captcha (another suggestion made here on HN, and it uses a local Altcha).
Our main challenge continues to be discoverability and outreach because we want to do it ethically. Ideas are welcome! We’ve been sponsoring open source projects, open source maintainers, and indie, small-web, and privacy-related websites and applications. This month was Caddy [3]!
Feature-wise, for July we’ve already shipped a lot of visible and less visible things. We’re currently looking into increasing our own index, focused on indie/small web, and plan to add a couple of new search providers in the upcoming weeks.
Thank you for your kindness!

I've been migrating marginalia search off docker-compose and onto systemd.
Between NUMA-concerns and the need to use multiple public IPs, I'm coaxed into a pretty exotic setup no matter what I choose to go with. Was pretty finnicky to set up, but it seems to work pretty well all said and done. Systemd is certainly feeling less floaty than docker (and even moreso kubernetes, which was never an option).
I also shaved like 10ms off response times since I no longer need an additional reverse proxy to deal with docker's networking magic, and can point nginx straight to the network namespaced services' IPs.
This in service of sequestering all wide domains (as in having tens of thousands of subdomains) to their separate crawler and index partition, as their (per top-domain) rate limits are part of why crawls take so long for the main crawler. Couldn't do that on docker because its ipvlan management is so jank you need spare IPs to reliably restart services.

I was an experienced game designer and producer (mostly RTS and narrative RPG). Some years ago, my career was derailed by major health developments. Since then, I haven't been able to work as I once did. I didn't expect I'd be able to meaningfully contribute to a game again.
Earlier this year, a colleague encouraged me to experiment with Claude Code. So now I have a little game project. :) Being unfamiliar with genAI, I chose something modest so that I'd more likely be able to push it to a fairly polished state.
Tentatively called Vestiges, it's a single player 2D roguelite strategy game with meta progression, some narrative, and a card minigame (the latter inspired by work I did on Star Wars: Knights of the Old Republic II). It's set in the near future. You are using software (the game) to navigate a person's digitized mind, reading their memories.
I hope to have a playable demo within the next month or so.
Big fan of SW:KOTOR series. Would love to test Vestiges when ready.
You should consider creating the game on Steam, so you can start building your audience.
Thanks! I've been hesitant about Steam because of the strong anti-genAI sentiments there. (And the initial fee to set-up a game's page.) You are right, though, and I probably should just push past my reservations.
(When I began this effort, I was just enjoying feeling productive again and didn't have any real plan to release. But I've been pleased enough with how it's been coming along that I've started seriously thinking about it.)
The anti-AI crowd on Steam only really seems to care about it being used for art, from what I've seen in reviews.
That's useful context, thanks. I might be in a grey area on that front. Vestiges has no genAI-created images, textures, etc. Pretty much all of the (non-text) visuals are generated at runtime using Godot's 2D vector drawing capabilities.
(I've considered trying to find an artist to work with to have professional 2D art.)
That’s just pure pazaak! Would totally like to see this game
Yes, the minigame is like Pazaak. I've prototyped two more radical variants that might also make the cut.
I'd be interested in the demo!!
I'd love to try it out too.
We are working on our two site-search search engines Monocle Search [0] and SearchCue [1]. The former is squarely aimed at people using Squarespace, whereas our newer offering SearchCue is aimed at anyone with a site that wants to add search.
We used Meilisearch as the search backend in the beginning but have since replaced it with a quite sophisticated search stack built around Tantivy [2]. We now support crawling and indexing of pages, most common office documents and PDFs, run OCR and feature extraction of images you might have, offer typeahead search with the aim of giving you providing answers as fast as you can type, as well as more classic agentic/conversational ai search.
There have been quite a number of interesting optimization challenges to solve in case anyone is interested. We have search nodes distributed around the globe to provide the lowest possible latency regardless of where the end-user sits.
We are also working on some other smaller side projects, but they aren't quite ready to launch yet.

1. Translating 1000s of NeoLatin, Chinese and Sanskrit books for the first time
At the Embassy of the Free Mind in Amsterdam, we’ve created https://SourceLibrary.org, a collection of over 15,000 translations of Renaissance and premodern books in NeoLatin, Chinese, Sanskrit, etc. There are a lot of beautiful books to look at — and you can use it with Claude code. API keys available: https://SourceLibrary.org/developers.
2. Replicating the design patterns of contemporary AI services
I’ve created a web app, desktop application and API for organizations needing European hardware and data protections. It’s a nice interface on top of Scaleway in France, so low carbon too. See https://makemode.eu
Support, feedback or even participation on these projects is very welcome.

I was annoyed by the speed of docker on Mac’s, so I took a journey and decided to rewrite everything about it. DD was original working name and I’m in process of rebranding. But we can run docker on Mac’s with no vm. And its destroying qemu. We have plenty of new features that are comming. Rendering native apps, workspaces, much more.
Thank you! A project like this was on my wishlist for a long time. Colleagues looked at me like I'm weird when I was saying containers without a VM should be possible on macOS. I switched to a Linux laptop because I couldn't stand the experience of working with Docker on macos.
I wonder if some of the macOS sandboxing features can be used instead of relying solely on the JIT
Yeah docker Mac expirience is pretty bad especially the x86 is just painful, and to your comment (about security), it should not really matter in practice, in fact we used both, but goal really is to run secure sandboxes that are processes without performance impact.
Hi HN, still making progress on Circuitscript, a Python-inspired language for describing electronic schematics: https://circuitscript.net/. You can try it in the browser via the Bench IDE: https://bench.circuitscript.net/
The biggest addition in the past month is initial support for ngspice netlist export — you can now take a Circuitscript design and export it to a SPICE netlist for ngspice simulation. This is a step toward closing the loop between describing a circuit and verifying its behavior, all from the same source file.
I have also added bus support, which makes wide parallel connections like data/interface (I2C, SPI, etc.) lines much less tedious to connect up.
Recently I produced and tested a 161-LED charlieplexed array in Circuitscript, using nested for-loops to generate the array instead of copy-pasting every LED and connection by hand. I plan to write a blog post soon to document this design.
As always, the motivation is to describe schematics as code rather than by clicking around graphical CAD tools (KiCad, Allegro, Altium, etc.). I want to spend time on the design itself, with code expressing the intentions clearly and reviewable in text.
Feedback welcome, especially from anyone frustrated with graphical schematic tools! If you have a KiCad design you'd like to convert to Circuitscript, please reach out to me. I'm looking to test the limits of the language and happy to help with the conversion.
Today I'm carrying on looking for a literary agent to represent me for my young adult speculative fiction. Long after human civ collapsed, crows have evolved to speak and are undergoing their own industrial revolution when they discover an asteroid heading towards earth. My 10 year old read it for the first time yesterday and loved it. That's made it all worth it already even if it doesn't get published.
Tonight is a meeting of a local group growing hemp locally, processing and spinning by hand to make an item of clothing locally and sustainably between us all.
Just spent the weekend at a wing chin gathering with some incredible people. They showed me so much I need at least 2 weeks to think about it all.
Apart from that I’m starting college to study therapy and counselling soon so I'm trying to read up to be a bit prepared.
> crows have evolved to speak and are undergoing their own industrial revolution
That's all very well and good, but what of the Caws of Art ?!
Working on Push Realm (https://pushrealm.com) the AI solution sharing network. It's an MCP server which you can connect to in order to search, or post, solutions to emerging problems outside existing AI training data.
The original idea was just "Stackoverflow but for AI agents" but I have tweaked it a lot, learning that humans and agents work in very different ways.
There are multiple potential benefits, the most important to me is avoiding token waste. Why are we all burning tokens solving the same issues with frontier models if we can simply share solutions?
Secondary to this, because each solution logs the model which made the initial post AND subsequent edits, it will hopefully become a helpful guide to the specialties of each models, long term. If one model confidently posts solutions but another always finds important security caveats, for example.
How do you prevent prompt injections?
Thr future of programs
A self-hostable Claude Tag or OAI Work [0].
A while ago, I realized that most new agent harnesses being built must be hosted on your machine or on a VM--in other words the agent needs a full OS process at all times.
But we do not have good harnesses being built that are multi-tenant, do not use compute while they are paused, but are are still as powerful as, say, Claude Code or Codex, OpenClaw.
So I set out to build one. I realized that the best substrate for these kind of agents are durable workflow engines. I'm currently supporting Temporal. AFAIK much of OAI agent infra is built on Temporal too. My harness is decidedly not just another agent SDK, but rather a battery-included product.

Just a personal project right now but it's a music metadata aggregator.
I find that nobody really knows how to do this. Machine learning can detect some song attributes well (bpm, ez right?) but it's inconsistent with some things (eg mood, spotify valence)
I prefer to only add metadata that I can rely on: track credits & instruments (when available), lyrics, bpm / "energy" and genre. At least that's what I've got for now. I'm not adding anything unreliable.
So far I'm able to pick a genre, artist or even better, song and it gives me a list of tracks that are similar. I can alter the weights of "era", "instruments", "genre".
So far i haven't run old school NLP on the lyrics but that's the next step. It's likely to be far more informative than "valence"
Anyway, not public, still very alpha but I like it and find it useful.
I'm working on a tool to automatically sync your work-in-progress music from your DAW (digital audio workstation, like Ableton Live, etc), to your phone. Basically a workflow tool for musicians and producers! Also has some quick share/feedback functionality too. Would love some feedback since it's still in really early stages. Already integrates with Ableton, Bitwig, Cubase, and GarageBand. https://trackid.com.
I used to work at Native Instruments, and super happy to now work on something for myself instead.
I am continuing to work on Akariq [0] which provides travel eSIM data plans to 180+ countries around the world. I have had many paying customers over the past few months from Vietnam to Mexico to Europe and US of course. The three benefits of using Akariq are
1) No app, no user account which leads to literally 3-click install
2) Full transparency - you know what you are getting. A lot of other eSIM providers hide details like unlimited plan speed caps etc
3) I connect to the best network available in the country. For example, someone like Airalo would connect to VTC in Vietnam, I offer Viettel which is the undisputed local network king.
And obviously, I am 2-3x cheaper than Airalo and the big players.
[0] https://akariq.com/
I like but for many of my regular destinations you are still 2-3x more expensive than what I can trivially find myself, especially longer visiting times and more data.
Thank You! Can you please tell me your destinations?
I plan to make the higher volume data plans cheaper very soon. I'm happy to provide you temporary code to make it cheaper for longer visits you have soonish. Can you e-mail me at `hello@akariq.com`? I don't see an e-mail on your profile.
The one thing I want to add is that cheaper also depends on quality. So for example, if you look at Vietnam - I may not be cheaper than Airalo. But ... a big but, I offer network on Viettel while Airalo does on VTC. So, I am cheaper for what you get for the quality. In addition, I don't route data via HongKong or China to make it cheap. I have in country / region networks for like 87 countries and I keep improving [0]. Very few providers on the market can guarantee that.
[0] https://akariq.com/en/network-quality/
I can confirm that you are completely right about Vietnam mobile networks. I could only reliably work after getting a real viettel sim. Even viettel branded stores sell some bootleg sim to tourists that work terribly.
The problem with eSIM is that usually there is no way to judge the quality until you buy one, so people sort by price and choose the cheapest. If your solution offers the best network in the country then I’m interested, because even at x2 or x3 price it doesn’t matter much compared to the other expenses when traveling.
Not sure how you can convince customers outside the hn bubble.
My passion project is an LP-sleeve-sized music streamer built around an ARM compute module, a custom PCB carrier board and an industrial 17" square display.

This is a really cool idea. Been thinking of a way to introduce my daughter to my old LPs without her wrecking the vinyl, and this might be a good compromise!
I heard an episode of the Odd Lots podcast about HayWire (haywireag.com), a site that pulls public data from government PDFs + APIs, uses LLMs to parse it and turns it into an easily readable website that has all of the latest info on hay prices.
The host made an offhand mention that there's probably a bunch of other similar sites that could be created with all the of useful but difficult-to-access government data out there. That sounded interesting, so I thought I'd give it a whirl!
Working on a few of them, including The Waterline (https://the-waterline.com/) for water info for the western US, The Scramble (https://the-scramble.com/) for egg prices, and The Dwell (https://the-dwell.com/) for container ship dwell times.
All pretty fascinating topics to learn about, plus it's been interesting to see how much of the website setup I can fully delegate to Claude. With Cloudflare to buy domains and put the sites up, a Google Service Account with access to Google Search Console and GA4 to create those properties and a Buttondown API key for weekly email sending, it's almost all hands off for me. Though it refuses to take control of the browser and create a new Buttondown account, which I was surprised is a red line.
Love this! Waterline still seemed cryptic but the scramble was a fun read. I am not following neither of these niches so just a passerby opinion!
https://digs.fm - like Goodreads, but for music.
As someone who's constantly on the look for new music to discover and being very deliberate about the things I'm listening, I needed a better way to organize the albums I want to listen to, listened and liked. And also I would like to see the discoveries of other folks who I know I like.
Original Show HN thread: https://news.ycombinator.com/item?id=32551862
I'm working on: https://pasal.id/ - A machine-readable database of Indonesian laws and regulations.
https://laws.sg/ - Singaporean statutes structured specifically for AI agents.
https://mylaw.my/ - Malaysian federal acts formatted for easy agent parsing.
I'm on a mission to make all Southeast Asian laws easily accessible by AI agents!
What does machine readable mean? And what does easily accessible by AI agents mean? Can agents read regular web pages? As in, what is the difference between this and regular web pages?
I'm working on TTZ, a sort of, pardon the expression, next-gen terminal protocol.
I wanted a middle ground between web apps and Terminal UI that allows for things like raster images, vector graphics, simple audio support and file transfer; to let me move more apps and workflows from web apps to a lighter experience.
I have an old laptop that I love and is very nice to use, but since it has only 2 GB of RAM, using multiple web apps is out of the question. I live on the terminal and SSH, but it has its own limitations, like spotty support for images, no audio at all, and ReGis (for vector graphics) support is not available in a lot of terminals.
I've recently finished implementing both client and server libraries for multiple languages (with the help of AI), and right now I'm in the process of fully testing and squashing all bugs and inconsistencies. Next, I will port a couple of applications as a proof of concept.
I plan to publish the source code very soon to receive feedback.
Just finished Veritas - Truth Across Cultures[1]. The idea is that many different cultures have written sayings that are basically the same. Similar to how one would give more credence to more than one person saying the same thing, the same is true for cultures. So, this is like my catalogue of what diverse cultures agree on. I have been promoting this book. [2][3]

I am working on an online Talmud to explore the old text in new ways! Its been a pet project of mine for over 4/5 years, and to my knowledge its the only attempt to blend the classic format of the text (Tzurat Hadaf) and AI enhanced commentaries sourced from the classical texts
https://talmud.dev/?lang=en
Update: Hopefully this can help those who completely misunderstand the nuance of this ancient text (usually from antisemitism) to better understand what they are reading.
I'm working on a collection of networked games, around the central theme of a lockstep deterministic network model with 'delay frames' (between acting directly on user input and progressing actual shared network state).
You can try this here: https://locksteparcade.com/Client
Games included in the arcade, currently:
- Neon Swarm, a take on the classic lemmings game, with multiplayer versus and coop modes
- Serpents, a snake game (where you eat food, grow a tail and need to avoid this growing tail), with inertial movement and multiplayer
- Spirits, an homage to N++, where you work together to get someone to the exit, while avoiding enemies, figuring out how to open doors, and so on
- Pilots, a multiplayer asteroids battle with homing missiles
Each game solves the network delay problem (the problem of providing immediate feedback to user input and hiding the fact that actual changes to shared state are delayed) differently, and it has been very interesting to work through a bunch of different approaches to this.
If anyone else here is working on multiplayer network games, I'm very interested in setting up a regular "play each other's games" session.
The idea is that regularly playing with other game developers will help develop a kind of 'scene' (where you get a group of people together who make work in public but really aimed at each other, pushing and unblocking one another to become bolder and better at an accelerating rate, as described here: https://www.henrikkarlsson.xyz/p/scene-creation-engines ).
If you are interested, let me know!
After 2 months of work I finally finished calibration of first 2 channels of my automatic test equipment and now I can finally measure diode curves.
Happily continuing work on https://cardcast.gg. It's a way for my friends and I to play Magic: The Gathering online using a webcam. Spelltable has been neglected by WoTC, and we wanted more features, so I rolled my own (and learned some Computer Vision stuff in the process!) Most recently I rolled out automated card tracking, so there's no more need to click on cards to know what they are, they just automatically scan on a set interval. I also moved over to using livekit for the service, and man, I should've done that sooner. If you play MTG, I'm looking for more people to come give me feedback and contribute. Feels like something others can benefit from!
An operating system for self-hosting
https://github.com/malmoos/malmo
I saw the options out there were not fully open source, or had other limitations so I started working on this better one. Based on Debian, apps are docker containers.
I do work to adapt current open source apps, but it's so great to make them available as one click install.
I want to make it easy to run on a cloud VM or an old PC kept in the pantry. There are so many cases for self-hosting now that we need to make it easier to do
I’m working on https://gnooma.com, a lightweight tool for reducing knowledge drift in teams.
It introduces a new document type called a gnoom: a living document that knows who has read it. When the document changes, read confirmations reset, so you can see who is up to date.
I built it because important decisions kept getting buried in chats and then discussed all over again.
It’s a free beta and doesn’t require an email. Curious if anyone else has this problem. I’d also appreciate any feedback on Gnooma.
I have been working on dock bar for Linux
* https://docking.cc
* https://github.com/edumucelli/docking
It has X11 and Wayland support, pre-built packages for all major distributions, almost 60 baked in applets.
For those into Linux and using a dock bar, I am sure you will like it.
I am working on ShopSpec (https://shopspec.io/), a tool for designing bookshelves and cabinets. Enter the dimensions and it generates the parts, cuts, sheet layout, and build steps.
I built it because I wanted to spend less time drawing boxes in CAD and more time building them. Still early and I'd love feedback from other woodworkers.
My side project is now codebase explainability. I basically don't buy the premise that we just have to give up on comprehension as code generation scales; I just think that text is too limited by itself. So going a step deeper than asking Claudex "teach me this project", but having it produce a navigable snapshot of what's going on.
Big bang prototypes have been pretty awful, even after feeding the LLMs huge documents / wishlists / descriptions of how it should work, etc. Part of the experiment was giving LLMs some leeway to make product decisions with a lot of north star guidance, but AFAICT they are really bad at this. I also tried basic bottom-up efforts, which have been better but obviously more tedious. Now I'm trying to find a more scalable bottom-up approach that is more LLM-accelerated
I posted about my project below - https://github.com/0x007BA7/codebook
But maybe you should checkout the tools it’s based on, sem - https://github.com/Ataraxy-Labs/sem and ultimately treesitter. They at least give a more structured approach to dealing with code than simple text.
This is great stuff; I've been prototyping with a few language-specific parsers like the Golang and the polyglot approach looks really helpful for me
Yeah I hope the links are helpful
Any promising techniques so far? I’m working on a rather large monorepo and very few people on the team are managing to keep up with it. Looking for ideas to improve comprehension.

I'm continuing to build out OneBusAway Cloud (Heroku for public transit), just like last month. https://onebusawaycloud.com. Since last month, the overall polish and feature completeness of the product has improved substantially, and we're starting to see meaningful inbound interest.
Beyond that, I've been plugging away on improving the user experience of the OneBusAway iOS app, and plan on launching a major overhaul of the stop page experience later this week: https://bsky.app/profile/onebusaway.bsky.social/post/3mqj4ua...
I also recruited a new Android app maintainer who has been doing amazing work!
If you want to explore our new transit API server, I wrote up a blog post a couple months ago to walk you through the basics: https://opentransitsoftwarefoundation.org/2026/04/setting-up... (data for your location can be found at https://www.transit.land/operators)
You can find all of our OSS work at https://github.com/onebusaway — we have projects written in SvelteKit, Go, Swift, Kotlin, and much more.
I have been working on Stencilize: https://stencilize.me/
It's a little webapp that solved a problem I had when ordering PCBs: I was too cheap to buy the stencil when ordering the PCBs from China, but then I regretted it when I had to paste by hand. Because of this, I did the PCB Designer -> DXF -> CAD -> Add margin -> Add outline -> Print workflow by hand, but that became very tedious, so I built this to automate it.
It runs entirely on your local machine and it is hosted on Cloudflare pages, with the only costs for me being a domain name.
Two side projects I’m actively working on:
https://openaltfinder.com - To help people discover selfhost-able open source projects.
Been maintaining this for almost a year, and it’s been fun. Keeps me up to date with new OSS.
https://getpinnd.com - A small social network for map makers to created shared lists of places.
Was just a spur of the moment, and ended up building it in little than a week.
Quick feedback: I searched "n8n" and it did not surface SimStudio [0], which is pretty much an open source clone of it.

Thank you, hadn’t heard or SimStudio before, have added it to my list of projects to add.
Nice. I tried to submit a project on the former. However CloudFlare seems to be blocking me from submitting the form.
This is a common issue for all of us in Viet Nam though, not sure if there's anything you can do your side. I'll figure out how to get my submission through later :)
Sorry about that, wasn't aware that this was an issue for people in Vietnam. If you want, you can direct email me at contact[at]openaltfinder[dot]com, or you can reply here with the project you wanted to submit.

I'm working on https://gatewai.studio in my free time - it is an agentic workflow engine for content creators.
There are 40+ nodes that can be used to generate and modify images, videos, audio, or vector graphics. Some of them include Crop, Resize, LUT extraction, Levels, Audio Compressor, Ken Burns, Mesh Warp, Recorder, Noise Gate, Compositor and Signal Builder.
It also supports signals for dynamic and time-based configuration values for the nodes. For example, making blur strength change from 30 to 0 gradually in the first 2 seconds of a video.
It uses a WebGPU pipeline for rendering and a homebaked engine for workflow processing.
It is free to use except for the AI nodes and workflow agent. It is not officially released yet, and feedback would be very valuable.
Continuing to build my olive oil tracking site (https://www.extravirginvault.com/) and pipeline. Freshness is king in the world of olive oil, and I hope to highlight to people they can find high quality, fresh olive oil produced near them.
It's been received well from producers and olive oil enthusiasts (e.g. looking for specific chemistry, cultivars and similar oils) but I feel like I've been shadow banned from Google - I seem to get more traffic from DuckDuckGo and Bing.
Working on gisti.ai which eventually will be a fleet of Product and Customer Operations AI agents that continuously analyze customer interactions, identify the churn risk and automatically route the right actions: code fixes to engineering, product insights to PMs, and operational tasks to customer operations.
Today, Gisti ingests customer feedback from every channel your customers already use, synthesizes it into a prioritized, evidence-backed list of opportunities, and lets product teams interact with an AI agent to explore, validate, and act on each one. We are building Gisti with a philosophy of complete automation for specific workflows.
We are looking for Design Partners, please hit me up at shubham@gisti.ai. I will be in SF late August if you prefer in-person meetings.
Please ping me / email me if you are interested in a demo / demo account for deeper analysis.

I made it specifically to bring back what was amazing about the old internet, and do it as authentically as possible. takes inspiration from old internet messageboards, usenet, bbs, and pubnix hosts. it has sealed mail, boards, an rss reader, built-in media player, custom profiles, a links directory, and quite a bit more.
it's just a little hobby art project for me but i've really appreciated talking to like minded people in a calm space.
This is wonderful. I've often wondered about small, human-only groups forming in tighter social circles, which can be hard to find.
Thank you! That's the idea, and even though its been a slow burn, the conversations have been interesting and rewarding. One of the funniest proof of concept so far was, someone asked how to route a guitar body to fit a new bridge on a network with maybe a dozen active people at the time. Within like a day, a total stranger with an actual woodshop and eight spare guitars showed up with real technical advice and offered him a discount on one of the guitars. Maybe it was a fluke, but it really struck me, and there have been a number of small interactions since that one that really remind me why I loved the early web so much.
Joined. I love the aesthetic and looks like there are active users. Very promising.
Awesome, looking forward to seeing you on the boards. Yeah, we have a decent little group of active posters and we've been adding to that number slowly but consistently since I put it online a few weeks ago.
It's been fun and I've learned starting a community is a lot harder than it looks. Maybe I'll write a post on what I've learned sometime. TLDR and probably no surprise to most: making the software is the easy part.

I am working on hammer https://thehammer.io/ , it is a voice device that I have build and have been using for past several months for texting and getting answers to my questions via AI chatbots.
I started with the idea of replacing my phone with a texting device that can still keep me connected but realized phone has became utilitarian that it is not possible to replace it.
I still have to take my phone when I am outside but when I am home or at work, I now use hammer exclusively to text or to get answers. The most benefit I have got is that I don’t have the urge to open my phone and go on endless scrolling binge.

This month I continue working on to refine my coding agent harness https://github.com/vinhnx/VTCode. Recently, I've added back Anthropic Claude Fable 5 and OpenAI GPT 5.6 models family (Sol, Luna, Terra). Fortunately, I've had support from the open source community and VT Code has advanced. I hope you give it a try.
I've just released in beta, a web-based application called Verse Draft: https://versedraft.com
I wanted to create an all-in-one writing studio where fiction writers can keep all the details for an entire universe in one place while crafting stories, novels, movie scripts, TV series, or stage plays.
I also wanted the ability to allow for the limited use of AI in a way that only functions as a sounding board and does not write for the user; Where fiction writers could have access to tools such as a virtual assistant that they can converse with about their stories and world-building, but without it writing anything for them.
There is also an option to use the application without any AI tools at all.
I'm slowly building an IDE with mentor/skill-level awareness baked in.
I've noticed that juniors and new hires often fall into an impostor-syndrome trap when reading an unfamiliar codebase or reviewing a senior peer's PR. Documentation helps, but it usually runs into the curse of knowledge: it's written by someone who's spent so much time in the code that they've lost sight of what it's like to be new to it.
I've always liked the rubber-ducking process, and mob programming too, so I'm trying to combine both into a modern AI-enhanced form:
- "Duckies" with distinct personalities (really, skills) that each specialize in a particular kind of problem
- "Teachable moments" (working title): small bubbles that surface something novel, tangential, or foundational as you work
- Skill-level detection and a routing model, so the app doesn't overwhelm or annoy you with explanations you don't need
Each duck also runs on a tiered memory model, rather than one flat context window. There's a core memory, essentially the duck's resume, defining what it's actually skilled at. Above that sits a longer-term memory for company standards and code style, and a separate long-term memory scoped to the project itself. Short-term memory then covers whatever task or feature is currently in flight. The idea is that a duck should reason more like a team member with a real employment history than a chatbot that forgets everything between sessions.
It's called Duckies AI (https://www.duckiesai.com). It’s very rough, working locally, but not in a state I’m ready to ship yet. I'm hoping to ship an alpha soon. Turns out there are a LOT of table-stakes features an IDE needs.
I love this. I have been building and IDE for myself. My non-technical team wants to use it after using lovable and things like that. I started building a dialect of JavaScript to make more approachable but that seems impossible the more I get into it.
Have you thought about building it as a plugin, e.g. for Jetbrains?
I started down this path, although with a VS Code plugin, but I didn’t find the ability to visually tie into the text editor with chat modals/bubbles. It’s likely what I would pivot to if I don’t like the amount of effort necessary to build the basics.
Cute IDE LOL I like the design. It feels like a good WhatsApp vibe to me.
Finished my hobbyist analog computer [1]. (Just need to make a YouTube video, blog about it…)

As an engineering manager and later a director, a regular and often difficult task was assigning ROI to projects that had recognizable but diffuse impact. It's easy to calculate a dollar figure for certain projects by projecting additional conversions or revenue. It's harder for a security or SRE project that doesn't have a direct impact on those things, but can help reduce risk or empower a bunch of other teams to operate more safely or move more quickly.
I have been working on a set of tools and standard formulas that can be applied to these cases and demonstrate a more accurate view of a team's or department's overall ROI. The plan is to open-source the bulk of it, but provide a hosted service for folks who don't want to manage it themselves.
I'm working on a no upload, no account, no server-side preprocessing online viewer for schematics, PCB layouts, 3D boards and BOMs called ECAD Forge -> https://ecadforge.app/
A cliché project, but working on a photo library browser that works in a way that I want it. Technically, the interesting thing is a UI that is reusable across all of my target platforms (desktop, mobile and in-browser with WASM). Rust+GPUI is the first platform I've seen that makes this possible with a reasonable performance and quality.

I am working on Spreadsheet Preview, embed and preview Excel files in any website/web app. Just like PDF.js for pdf files. Check it out at https://spreadsheetpreview.com
I've been working on MacDispatch https://macdispatch.jurajb.dev/
A macOS menu bar app to alert when apps start using too much resources and drain your battery. Helped me diagnose many leaking Chrome tabs and macOS bugged services.
I'll give this a go, battery has been draining pretty quick with all this multi agent dev
This is a Chrome extension that records lots of details in a usage session. Stuff like network calls, console logs, screenshots and also optionally screenshots and user narration
Tools like this exist, but every one I tried is uploading the session details somewhere in their cloud and try to monetize this.
So I built the version I wanted: free, open source, and local. There is no account, no backend, no telemetry. Sessions live in IndexedDB in your browser and exported as a zip.
What it records:
* Clicks, typing, page changes, network requests and responses, console errors screenshots, video with sound
* Your voice, transcribed and placed next to what you were doing at the time
* Annotations: Arrows and boxes you draw on the page's screenshot
Note: Passwords, auth headers, and tokens are masked at capture time
All events are lined up in a timeline with timestamps
At export you pick a detail level with a live token estimate, so a long session still fits your model's context window.

In my free time, I'm building an iPad game to help Autistic kids practice real world skills. The game is called Pocketown. https://pocketown.app/
If you're a parent to an autistic child(like me), I'd love to talk to you about this.
If you know anyone who has an autistic child, It would be super helpful if you could tell them about this game.
Thanks!
Currently working on Agentry(https://agentry.run/) Runtime, connection, and deploy layer for building internal apps and automations with AI. You can build anything that you can build with Lovable, Replit etc. Your model, Your harness and your own Laptop/Server
some examples https://vessel-ops-dashboard-4c3976e79335c1aa.agentry.live/ https://local-goods-shop-54ce3b368e0d41f6.agentry.live/
I've been building a text editor. It uses a server-client model, with native/terminal/web clients using a shared (local) server instance. It integrates LSP/tree-sitter/ripgrep/Git/etc, and has a concept of 'workspaces' to easily switch between projects.
I spend less time in an editor now, but it's been satisfying being able to take features I've enjoyed from other editors and customise - and it's oriented a bit more towards exploring code than editing. Key-bindings are arranged such that bare letters are for motions, Shift- variants are then used to extend selections, Ctrl- bindings are for buffer mutations, and leader-prefixed bindings are application level (e.g., opening pickers).

I’m working on [Homestead](https://myhomestead.dev), which is my OSS solution for building personal apps. You can build web-apps and Homestead will handle backend, agent support, authentication, notifications, and a bunch of other stuff.
I’ve used it to build a grocery store list, credit card perk tracker, address book, mini-golf scorecard app, and a bunch more. It’s really helped having all of the “platform” stuff handled for me so I can just focus on the app.
I'm building a Go to WASM reactive UI framework called Goowee. Fine grained signals (no VDOM), components run once, SSR and hydration built in. The JS bridge is about 200 lines. Still experimental but I've thought about it thoroughly and have used it for the landing page of the project and some other projects of mine.
I know Go UI frameworks have a long history of not quite getting there. The bet I am making is that WASM is now fast enough, the tooling is mature enough, and the fine grained signal model avoids the VDOM overhead that held earlier attempts back. Would love an honest critique of whether the framework actually solves the problem and whether it's usable for other's development experience.
https://github.com/yogisalomo/goowee
Neat! I did a fair bit of toying with Go's WASM target early on and was able to port a couple neat things to the web. The sheer size of the WASM output though was a limiting factor for me, and I kind of stopped toying with it a number of years ago.
Are you using the built in WASM target? I've been told Tiny Go's WASM build target is worth investigating but haven't tried.
Yes, the size of the binary is quite big (~4MB for the landing page) but it's a trade-off that I'm taking with this approach and I think there will be ways to optimize for size.
I'm currently using the built-in WASM target but Tiny Go is one of the items that I have on v1.0 road map. Will give it a shot and see if it actually helps with the size without affecting any performance.
I built a fully locally hosted language learner app. It build language lessons based on a 4 year college curriculum, using a local LLM, Qwen TTS, local STT, and comfyUI image gen. I formulates themed lessons, around 'interesting' stories, generates dialogue, images, audio, quizzes, and pronunciation tests. Each lessons progress is tracked and new lessons are generated daily to reinforce concepts and extend past lesson story lines.
Overall it acts like a 'Choose your own adventure' book, but you learn while doing it. Currently supports Spanish, French, German, Japanese, and Simplified Chinese. Runs on a 4060 16GB card.
Gonna try to monetise it or open source it?
Right now it's just a personal project. Will see if it actually helps me remember my Spanish, then I might release it.
I've been working on Contextify: https://contextify.sh
Makes it easy to use Claude Code or Codex interchangeably across multiple computers. Personal editions are free, I have a hosted commercial cloud (workgroups share AI history) and commercial self-hosted option available.
It has macOS and Linux clients and I released a guide for setting up the source-available, self-hosted cloud option this week: https://contextify.sh/docs/self-hosted/
I am thinking about the other AI cli environments and providing support for those as well.
The color of the text and background of the Linux button contrast poorly in my opinion. It made it a bit hard to read.
I'm exploring triply periodic but non-minimal surfaces. https://codeberg.org/okaleniuk/faitps
Triply periodic minimal surfaces are the golden standard in thermal management, acoustics, and even medical applications. But minimality itself doesn't contribute much to practicality. We use them because they are simply studied better than the non-minimal surfaces.
So I'm studying the non-minimals. They are much more governable, what I link to is a demo of a surface builder with two levels of control. Next, they are conjugatable including conjugations with different period of self (that will be the following paper), they generalize nicely to non-periodic or partially periodic surfaces, and they work in other space configurations. E. g. I'm now playing with bi-periodic curves that cover the 2D space with self-replicating hexagons.
If all that I'm experimenting on today in 2D will turn out well in 3D too, we'll have a whole new direction in implicit modeling.
I've been working on https://weirdther.com/
A website that tells you how "weird" the weather has been in a specific location
Weird being the percentile difference to the weather since the year 2000
Would love to check it out. But seems the site is down
Kind of tangent of what everyone else is doing but making a minifigure/garage kit painting site.
If you're in the hobby, the issue is that keeping track of paint and color combinations is annoying and is very mind numbing since wet paint color differs from dry point colors, how colors combine due to transparency of the layers, and different companies have different binders/pigments.
Currently have the paint combination setup and trying to get minifigure gaussian splatting setup from an image (Used to work in gaussian splatting for a while and actually figured out how to improve vggt to get a better one-shot)
http://paint-production-1f6c.up.railway.app
AI resume spam has absolutely ruined hiring. I've seen countless stories of hiring managers complaining about receiving thousands of resumes within an hour of opening up a new job listing. Likewise, good qualified candidates are getting drowned out by loads of customized junk. I'm building a tool for the recruiters and hiring teams to combat this and bring some sanity back to the already challenging process. The general idea is to introduce a small bit of friction that will hopefully be not-too-impacting for legit applicants while stopping bots from proceeding.
First iteration is ready to fly, just working out the infrastructure at the moment. Hoping to drop this on Show HN soon. If anyone is interested in test driving this prior to launch, I've temporarily added my email to my profile.
I'm working on a large open-world terrain-rendering library for threejs's webgpu renderer! https://hello-terrain.kenny.wtf/
At its core, it uses quadtrees, and has affordances for arbitrary topologies. Check out the planet and donut-world demos!!!!
- https://hello-terrain.kenny.wtf/examples/torus - https://hello-terrain.kenny.wtf/examples/cube-sphere - https://hello-terrain.kenny.wtf/examples/raycast-character-c... (a little slow to load~)
This is great, and my users (turtlespaces.org) could absolutely use this (we use three and react), but you haven't specified any license?
Thanks! How silly of me, I will update the repo with an MIT License~
Great! Thanks so much, I'll let you know how it goes integrating it :)
Still working away at https://whistle-enterprise.com.
Have spent the last month giving the UI a bit of a modernisation refresh and simplifying/improving some elements based on early user feedback. There's also been a boat load of performance improvements in the dirarisation and document generation pipeline.
Feel free to download the prerelease version (its unsigned) here - https://downloads.blazingbanana.com/whistle-enterprise/unsta...
In the past few weeks, experimenting with a custom ai agent running entirely in the browser with sandboxed tools exec.
The core is built in Rust, a native CLI is built on top for local experimentation but the most interesting part is the web version: the core is built to WASM and get augmented with many tools in the JS land: - OPFS access (read, list, edit files) - Sandbox Python exec (Pyodide in WASM) - Sandbox DuckDB exec (DuckDB-WASM) - Draw charts - Show images - etc OpenAI Completions compatible API providers are supported.
But if you want a full local and sandboxed execution of the whole agent, the web version bundles also wllama to serve local GGUF models (with WebGPU optional support).
Github repo: https://github.com/rclement/cooper
Very cool work. I've been seeking solutions for running an agent in the browser for building artifacts on my project, which is a web artifact tool library called Exhibit. I'm starring this for later.
https://github.com/momja/Exhibit
Oh nice! I’ll take a look at it, I was thinking of implementing such mecanism in Cooper (I don’t know where it’s going, exploring the possibilities and practical usefulness)
I'm working on a website directory (intrasti.com), not really sure what the direction is other than I'd like to celebrate the best of the internet in a way that isn't pay to win, manipulative, or anything like that.
It's a slow business and engineering catalyst that I'm making progress with behind the scenes each day. Suffice to say I'm taking the scenic route!
Currently working on a unified website submission flow for submissions and topic creations (topics are collections of websites) and after that I'll be looking into overhauling the whole site focusing on accessibility and how I can make that a great experience.
I'm working on https://GovWeave.com/.
It's like a BuiltWith for Government. I am tracking all UK government spend and building a picture of software and rising/falling trends of various products in the government.
I worked as a government supplier and found it hard to find out what tech/solutions are in place without inside knowledge. My idea is that by opening the data, I can help more suppliers compete and foster innovation.
Something very small and simple compared to other ambitious projects here :)
A TUI to control a crazyflie nano drone. This is mostly a rust learning project - but insanely fun because it leads to something flying through my living room.

I am working on a local first LLM frontend that saves all chats directly to your hard drive and ships in a single index.html file artifact that you can self host.
No code to show yet. I'm taking the time it requires.
Recently launched https://hellbox.com (formerly Font Proof) and am still actively working on it. It is a native macOS app for font proofing. It watches your type design software like Glyphs, RoboFont, and FontLab or any font file or designspace on your machine and reloads the font proof when you save.

I was kind of disappointed at our HOA management system so I made my own: https://hoamy.app
Started of manually, later stages I used AI for implementing similar pages, and then for reviewing my own code.
(It was also an excuse to work with Nuxt / Nuxt UI as I loved the development of those projects and wanted to implement something with it.)

MatGoat (https://matgoat.com/en/): a software for managing BJJ and martial arts academies that it's both easy to use and have everything they need like assistance tracking, payments, communications, etc.
It's going quite well so far with growing MRR each month.
Lately, I've been trying to focus more on marketing, and sales. I might try ads soon as well.
I'm working on Flex (https://flexenv.com/)
I am speaking to initial customers and from my initial pain at my day job it was going to be a way to be "Lovable for your existing product" . But it also seems like it might turn into "internal cloud to host dashboards non-technical people are making with Claude".
I'd love to talk to anyone that's in Product or Ops or Sales or Account Management or Customer Success who'd either like to make changes to their existing product without the need for a developer. Or maybe they have thrown something together with Claude and have no idea how to "get it into production".
Still doing https://rcarmo.github.io/projects/piclaw (which is my main “IDE” now), ended up forking https://github.com/rcarmo/tau-prime to have something I could run on my iPad (and on the Mac, with a simple sandbox), hoping to get back to 3D printing (https://taoofmac.com/space/notes/2026/07/12/1230) and playing with hardware.
Oh, and migrating most of my stuff to microvms on https://rcarmo.github.io/projects/pve-microvm/
Enjoying the work on MyTraL - sovereign athlete / personal training log: https://mytral.fitness/
I went on sabbatical to fulfill my dream project - consolidating years of training logs. I'm enjoying the technical challenges involved - digitizing paper hand written logs / visual models, navigating the maze of athletic metrics with their crazy trademarked names and multidimensional models. Having fun building AI coaches: agents ranging in character from Al Pacino in Any Given Sunday to the coach from my teenage years, utilizing ICL model-based predictions, ... and more.
The best part is the rush of memories while ingesting my own history - photos and recordings I completely forgot, as well as navigating data shared by friends.
This month has Strava & LeCol everesting challenge - signed up and added support that suits my needs to MyTraL. Good times.
https://pastmaps.com
This is my side project turned solo bootstrapped startup that I've been working on over the past 2.5 years. Pastmaps has been solely a US-focused platform since it's initial launch but I'm currently working on launching to the UK and Ireland within the next week. If all goes as planned then I should have a first wave of 30K fully digitized, hi-res, and fully georeferenced 1800s ordnance maps available soon to help folks discover the history all around them.
I'm likely going to need to start building out my own global LiDAR dataset next though. My coverage for the US is quite stellar thanks to the data provided by the USGS' 3DEP program but I'm way out of touch with what's available and possible in the EU. It's gonna be a challenge but I'm excited to dive in.
Self hosted media platform with similarity search, face search and clustering, a great fun media player with shuffle, VS mode where you rank your media resulting in an elo, remote access to app over the web, a TikTok style "swipe" mode of your own media. Started as just a good media viewer over 5 years ago but I just keep adding things. Has a small patreon following so people seem to like it. https://lowkeyviewer.com/
I am working on a few things:
* TimeTracker (https://time-tracker.hosgeldin.click/) because I needed a privacy friendly freelancing tool that I needed personally.
* A simple exercise tracker that my wife requested from me (https://daily-menu.hosgeldin.click/) - later I will build a menstruation tracker that is connected to the Daily Menu.
* My magnum opus, "MyApps" (https://myapps.ideasofhakki.com/) - This is no less than an OS running in your browser, equipped with whatever "Apps" written in it. I am building it with GunDB and Svelte and foundationally it will be a web of apps running completely in your device (i.e. offline first), with privacy and data security built-in.
* Cram school management SIS for Turkish education system (https://edusis.hosgeldin.click/)
I released 3 games my friend designed, and built a game framework in WebAssembly for building them. Some 9 or 10 months ago I asked my friend (legendary game designer Mike Elliott) if he wanted to work through his backlog of designs he has that he'd love to see brought to life. I'm very protective of my family life and dedicate a lot of my time to it, and have a normal full time job, and so LLM-agents really enabled being able to make stuff like this happen in a reasonable timeframe just working on and off in my free time.
I started them with ebitengine (Golang) but got somewhat frustrated with its web builds, and so built my own thing for small games that I want to work great on mobile or native PC, but also on web. I call it NanoGame, the host is written in Rust and the games are AssemblyScript. I've ported a number of other small games I had written to it as well, but haven't released any.
Two of the games I released a couple days ago were actually the ebitengine versions, but have partial ports to my framework, and the third I released the version using my stuff.
https://scramblequest.app - ebitengine, word search game where you slay monsters with the words, has a long campaign as well as a daily challenge and unlimited play
https://wordpeek.app - ebitengine, another word search game, this one reveals pieces of a picture and your goal is to guess the picture
https://playsilhouette.app - my own framework, this is a simple matching/hidden object(ish) game, more for kids
I also made a little umbrella site for them at https://playthese.wtf
Adding MCP support to the open-source metaverse Substrata (https://substrata.info/)
I'm working on hexora, a library that detects malicious Python code using static analysis and machine learning.
Recently, I've added a simple ML model to filter out false positives. In the last month, I found and flagged more than 40 malicious Python packages.
Unlike the LLM approach, my library is not susceptible to prompt injection and deobfuscates Python code. Where LLMs see "obfuscated code, potentially harmful", my library decodes it and sees what's happening inside.

https://scan17.com/
Automated network port change detection. Scan17 provides a solution to the question:
So your CTO decides to outsource firewall management - and the vendor carelessly leaves a network port open, exposing your production database. How does your team find out before an attacker?
Think of it as nmap port scan diff-ing. If a network port goes from closed to open you get an email or webhook alert. There is a REST API for automated workflows and privately hosted engines will be supported for some plans. There is a wait-list form on the website if you want to stay in the loop.
If you work in infosec / cyber security and are interested in being an early product designer / beta tester, let's chat! See my profile for how to get in touch.
Desktop app bundled with an ai model and a local-first agent so nothing leaves your machine.
Last week I interviewed non-technical people about their experience with AI agents. Many couldn't even use them at all. Either they didn't want to share private data with ChatGPT or company policy prohibited it.
For those of you working with sensitive files – contracts, client records, financials, HR docs – I'd love to hear how you handle this today: simone [at] breadboards.io
https://cheapcloudstorage.eu - SSH-based cloud storage for long-term off-site backups.
A daily meditation "instrument". I'm a big fan of Waking Up but I've kinda outgrown the catalogue. I know what to do now. I just need a timer and a couple of prompts...
Underscore: https://underscore.audio/
On-demand, procedural audio programs (w/LLMs). I’m working to make these embeddable in software such as games and health/wellness apps.
Would love to hear how developers might use it.
I don't hear anything from the examples in Firefox or Chrome, on Windows 10.
Wow, that’s neat. Perfect for a hyperlight drifter style game.
I’ve been continuing work on https://mybulkcards.com, a phone app and website for scanning, organizing, and searching Pokémon card collections, especially the thousands of bulk cards that my daughter and I have in our closet from playing.
The goal hasn't changed too much, make building decks easier by knowing exactly what you own and where it’s stored. You organize cards into boxes, search your inventory, search friends’ collections, and keep track of trades instead of digging through a similar closet of cards that my daughter and I search for.
The fun part has been the AI. I trained computer vision models that run entirely on the phone to detect and identify Pokémon cards. Training has become the slowest part. For the model that needs to be retrained every new release, I’m up to about 5 hours per epoch on my M4 Mac with 16 GB of RAM.
The Android app is currently in public testing with people from my local Pokémon league. It’s built with React Native, and I’m working on the iPhone version next.
Still lots to build, mostly around product and ux, and because a recent stupid mistake on my part, backups and deployment safeguards.
I would love this for magic the gathering
I've been working on Wattle (https://wattle.app) for the past six months or so.
It started out in life as a bunch of post-it notes for friends who were watering my plants while I was on holiday, which evolved into a long text message, a Google Doc, a static site, a simple CMS, then Wattle. The more I look around, it seems like there are lots of use cases, so I'm having trouble with my positioning.
"Digital guidebooks for vacation rentals, home swaps, sitters, carers, and more."
The MVP was released last week :)
Funny, when I lent out my house I also covered it in PostIts.
When looking at a SaaS idea I always ask myself, "will this add enough value to compete with generic and free tool X?"
If your app is just pictures and text based (with AI search), I wonder if it adds enough value to compete with just a Google Doc that's also text and pictures (which surely also offers AI search). A Google Doc could also use comments to collect questions.
Visiting your home page, I was actually looking for AR (augmented reality) or plain camera powered features. E.g. point at a window sill and say "how do I open this?". Point at the washer controls and say "how do I do a fast wash? How long will it take?".
This could be especially useful for controls/labels in languages that the guest doesn't understand (easy to mistake bleach for detergent in Spanish for example). Maybe auto translation of all textual content and even pictures could be part of your app as well.
AR is something that I would love to see for myself!
For this particular scenario though, I've found that both hosts and guests responded far better to simplicity: a familiar UX (images/text) with a nice UI. Now that AI has become mainstream, adding this to search was also received well. Funnily enough, most of the past six months was spent culling features and streamlining/abstracting choices. The AI actually started out as multimodal and was reduced to text-only over time.
What I've learned from users is that a guidebook is non-critical until it is. When a guest can't figure out how the microwave works, they don't want to download an app, learn a new behaviour, and so on. They just want an answer as quickly as possible - from the host, or from a simple guidebook.
It's not so different from the host's perspective. Their focus is hosting, not creating the perfect resource. I added templates and "AI onboarding" (i.e. write a prompt / dump existing info as unstructured text) which people seemed to like. Turns out blank canvas syndrome is very real here as well. The AI organises existing info, creates placeholders for what's missing, and adds suggestions of what could be included.
When the guidebook fails to answer a question, it's logged so that the host can update it directly from the UI.
Completely agree with translation - it's on the list!
> they don't want to download an app
From the screenshot/device mocks on your site, I was under the impression that you were making an app for both host and guests to use. There's no 'browser chrome' visible in those pictures.
Could clarify that your app generates a site, or make that apparent from the screenshots.
I've been working on a web application for learning 倉頡輸法 https://demo.cangjieworkbook.com/ , no login required for the demo version (Cangjie Input method). It's a visual way of decomposing Chinese characters. It has a high initial learning curve so I've come up with a method based on the ways QWERTY is taught. I've added a few more texts and lessons in the last month. The most time consuming part is adding annotations to characters to show how they are composed, but it is worth doing. I already have a couple of users and they have given me helpful feedback. If you are interested, check it out and let me know how it goes.
https://vask.dev - websockets - Pusher alternative. It's Pusher compatible, but way cheaper and powered by Cloudflare.
https://tailstats.com - display data on almost any device (ios,android,macos).I've build this for myself so I don't have to build dashboards or mini-one-purpose-apps and clog menubar/workspace. It also works with AI agents via API and MCP so agents can create interactive cards.
In my free time, I'm building an iPad game to help Autistic kids practice real world skills in a virtual town - https://pocketown.app/
I'm working on a multiplayer RPG https://grimrain.com - calling it an MMO is quite bold, but the gameplay fits that genre. The game server is designed to be self-hostable too, so it's like Valheim meets OSRS
Looks great! As a tenured Runescape player, I like the graphics.
This looks amazing

Part of my job is to approve / reject MCP servers based on how secure they are and whether they are suitable for use in an enterprise environment. I was tired of my team being called the bottleneck to AI adoption, so I set out to automate the whole process.
I periodically collect the MCP servers and every new version from the Official MCP registry and assign them a score based on 29 distinct criteria like runtime guardrails (e.g. destructive tools, over broad permissions, rug pulls), SAST scans and transport & trust model.
As a result of this exercise, I found that 1 in every 10 MCP servers is pretty much unusable (score 40/100 or below). 18% of the popular MCP servers with 1000+ GitHub stars contain one or more security issues. 184 servers to date have changed their tool definitions after publication, which may indicate a "rug pull" attack.
I built this for security minded people who also want to be at the forefront of AI adoption and for security teams who are tired to be called the bottleneck.

I’m still working on a price API for the Counter-Strike 2 market that provides real-time & historical data.
Since my last post in February, I’ve gotten to ~25 paying users, which is cool considering it started as a fun project. Sorta a niche within a niche here.
The market is distributed across a bunch of 3rd-party marketplaces, and there's no 'simple' API that provides genuinely high-quality data for the few marketplaces that matter. It’s a surprisingly complex problem, which is probably why nobody else is bothering :).
It's been a super fun project, and I've been able to learn about collecting & managing a high (to me) scale of data, building an API from the ground-up, and creating my first 'commercial' website.
Website is @ https://cs2.sh/
The API is built w/ Go & Clickhouse, which I've also been super impressed with so far in terms of performance and efficiency.
Web design is inspired/somewhat taken from turbopuffer's site, since I really liked it.
Interesting and I also really liked the mobile website. Just wanted to let you know there is a bug on the frontend where the navbar does not collapse back when the user changes the page like going to pricing, the page state changes but the navbar stays on top hiding the change
Huh, thanks for letting me know, I'll look into it! I'm not able to view it, but I'm guessing it's some browser idiosyncrasy.
Still working on Study Engine and Nomnominees(more or less done for now).
StudyEngine is a webapp I'm using while doing my masters in comp sci. I upload lecture notes, textbooks, papers, etc. It then extracts topics and tracks my mastery of them over time. It uses an LLM to generate questions and flash cards. It loops in some newer learning science ideas. It tests recognition first(multiple choice), and then once a level of mastery is matched, it switches to recall. Working on adding RAG to it, so I can surface where in the source material something can be reviewed when going over quiz results. Currently just for me an some friends. If can get a good eval set up, I might work on optimizing cost and seeing if it could be opened up.
NomNominees is simple webapp that tracks James Beard, Great American Beer Festival, Festival of Barrel Aged Beers, and other awards. I use it when I'm traveling to find places to check out. Even just a cluster on a map shows me neighborhoods I might want to check out.

Launched a suite of media inspection and encoding tools a few months ago, based on FFmpeg. Slowly getting more customers.
https://video-commander.com
Constantly iterating through refinement and features. It's built on Rust + Tauri with a React frontend, in case anyone is curious.
I've created various open-source and commercial tools in the multimedia space over the last 10+ years and wanted to put it all together into something more premium with an IDE-like experience.
I'm not into video editing, but it looks very nice!
I frequently found myself needing to convert video files and everything is either paid, needs login, full of ads, or uploads your files. So I built my own tool that has none of that.
https://clipcut.dev
tscircuit! An open source framework for building circuits, we have a lightening fast autorouter so i spend lots of time debugging complex PCB routing problems
An "agent orchestrator" (or whatever you want to call it) that supports any cli agent. Trying to optimize for reducing cognitive load for working on different tasks at the same time with agents.
Currently doing final polishes on adding support for making it simple and easy to run agents and review the code remotely over ssh.
https://getbaton.dev
Mobile app that turns any recipe into 2-player mode, so you can cook together. Kind of like overcooked IRL.
https://nommer.ai
I'm working on a side project to clean up and fix EPUB files with transcription errors, incomplete or inaccurate metadata, and other issues. Users can accept/reject/edit the fixes as they go through it. I have the command-line interface and TUI working (thanks to Ratatui), but I'm still working on a Calibre plugin and web-based version using WASM.
Neat, have a project page?
https://shareourpics.com/
A focused and functional service for event hosts to collect guest photos through a shared link/QR code that leads to an upload page. Think photo gathering for weddings, bachelor/bachelorette parties, corporate events, big birthdays, etc.
There are many of these out there, but I found most unintuitive ("too complicated for Grandma"), too featureful, and/or much too expensive.
https://answerjournal.com/
AnswerJournal lets you save AI answers to a personal journal just by saying "save that to my AnswerJournal" mid-conversation.
Each answer gets its own URL, and posts can be public or private. It's a bit like GitHub meets Stack Overflow for the answers AI gives you.
It connects to any MCP-compatible AI (ChatGPT, Claude, Grok, etc.) through one server URL.
I've been throwing together some web-playable retro arcade games:
Rally-X: https://linsomniac.github.io/rally-xy/
Tempest: https://linsomniac.github.io/teapot/
Dig-Dug: https://linsomniac.github.io/digger/
And not an arcade game, but a multi-player throwback to a multiplayer shooter game my team used to play called nSnipes: https://github.com/linsomniac/isnipes
iSnipes does require downloading and running a server, the others you just play on the web.
I am building a solitaire solver for Zachtronic Solitaire. Especially the last one. It should allow you to take a pic of the screen and tell you if it's solvable and what the next moves could be.
I am working on a Jupyter notebook client for VisionOS. It allows for 3D data to be visualized on visionOS. Right now it supports point cloud data, USDZ models and Gaussian Splats. I am working on it to launch on the App Store. Sign up for more information at http://www.pulto.org
I've just finished this chrome extension recently: https://ypuf.com/
It helps me to automatically save a tab that's not been used in a while so it auto-closes it but saves it as well as having the ability to snooze a tab like how you'd do it in gmail.
Everything is locally stored with 100% privacy in mind.
And vim like navigation is natively done.
I made an HN filter for substacks and blogs: https://hnsubstacks.com/
It allowed me to explore a serverless deployement (on CF workers) with a toy project, that I wanted to make for myself.
Repo here: https://github.com/ariroffe/hnsubstacks/
I've started building a visualization tool for mobile robots using the VDA5050 communication standard.
There are some solutions already out there but most are either slow, resource intensive, or both. Especially for larger fleets of robots. I'm using it to learn more about VDA5050, Rust and wgpu.
I am taking my limited time before next job hunt and using coding agents to create a wego board strategy game inspired by Escape From Tarkov, Advanced Wars, and PhantomBrigade.
Just trying to learn C again, making things from scratch in a multiplatform way, interfacing with X11 on Linux and wasm on the browser.
It's been fun dealing with memory and C's weird design in this age of agentic coding.
We are creating an AI for science and engineering: https://vicena.ai
It's connected to all papers of course, and all kinds of scientific simulators and specialised models. But I'm currently in Shanghai talking to labs to join a CloudLab (and hopefully setting up our own robotic labs), so that AI can actually order real physical experiments that are executed cheaply, efficiently and seamlessly as tool calls.
Through experiments like autoresearch we have seen that AI is already, if not always smarter, at least more systematic than humans at following the scientific method relentlessly (hypothesis-experiment loop). Let's see what we can do by connecting it to the real-world :)
I've been building some sqlite plugins for playing with ngrams for text search. I'm not sure why, but I've learned a lot about the internal sqlite apis and it brings me a lot of joy. I would like to start a blog detailing some of this work but haven't found the time yet
I am helping a not-for-profit, [NavSahyog](https://navsahyog.org/), build a custom software for their entire operations and programs that also tracks longitudinal impact. The organization conducts programs for children in Indian villages after school to build live skills.
This is my second iteration because the first version felt like a simplistic fit and improvement over their existing vendor provided app.
I have now designed a domain model based on my understanding and observations. I have a day job so I can't spend a lot of time in sync with the team. I have created a web app where the NGO management can test scenarios (by recording voice), and the AI (Claude Agent SDK) runs it past the domain model. In case, there is a gap, they can persist the scenario. After every iteration, I read through the scenarios and assimilate them into the domain model.
I'm working on https://artifacts.iofold.com, a way to use artifacts (self contained html + optional assets like image/video/json) easily across agents, with feedback loop and docsend style wttribiti gates.
Have made it agent friendly enough that my teammates' agents can read and drop commennts on specs/storyboards etc, and my agent can close the loop by iterating with a new artifact version.
Many things:
- BrowserBox just landed WebAuthn (passkeys) - for now just macOS clients: https://github.com/BrowserBox/BrowserBox
- This website is served entirely from a 200Kb binary: https://200kb.freelang.dev

- All the government's 300K+ pages of UFO files released so far: https://hypergrid.systems/war.gov-ufo-viewer/microfilm5?fram...
And more
The copy on your 200kb page is such incomprehensible AI slop that reading it feels like I’m having a stroke.
Continuing partijgedrag again!
In summary, I pull public motion votings and do any kind of processing I want to give people a better insight in how the Dutch parties vote. There's a voting compass that gets a bit busy before elections.
It was a project by Erwin and I would like to continue the work.
I'm looking at the long-term image and have high hopes other countries would enjoy this too
My daily word game “Snibble” [0]
It’s basically snake meets scrabble meets PvP stealing. It’s a novel idea and I think it’s cool it hasn’t really been done before :)
The issue is it’s too complicated, the onboarding is dogwater, and the aesthetic is too complex
So I’ve spent the weekend fixing onboarding, fixing and relaxing the visuals mix and simplifying mechanics.
I’ve also tested LLMs playing the game through a harness I wrote. LLMs get smashed, they can form words and steal, but they lose badly to conventional bots.
I’ll be exposing an LLM leaderboard on my next release (hoping this weekend) with links to game replays for the LLMs.
Would love for people to give it a try, give me some feedback, and say what you’d love to see on the roadmap.
[0] - https://snibble.gg/
Created with a from scratch custom engine, pure typescript almost no dependencies
Completed games can be “replayed” and replays can fit in a QR code upto 30 minute games. So I think that’s pretty cool
Fun game! How do I “eat” on mobile? I tried tapping the # on the tail, to no avail
Thanks! Ha that’s the onboarding issue in play :( you’re actually meant to eat your tail by navigating your head to your tail
But everyone who has played has had the same feedback lol so that’s what I’ve been changing this weekend :)
Thanks heaps for trying it!
Oh got it. Very fun, great work.
Thank you so much :) hopefully the new build this weekend fixes the teething issues
I’m working on https://checkpost.dev, a lightweight and easy-to-use osquery manager. It is open source, easy to self-host, and ships as a single binary. It only requires osquery to be installed on the endpoints. Checkpost is readonly and doesn't make any changes on the enrolled hosts.
It can run adhoc or scheduled queries and send the results to ClickHouse, or store them locally in Parquet files and use DuckDB to browse the results. It can also initiate YARA scans and collect the results. It also supports policy evaluation and alerting.
Nice. What's the end-goal of this product look like in next 2 years ?
I’m already happy with the current set of features, and I don’t expect to add many new ones. I want Checkpost to be something you can host once and spend very little time managing.
One of my goals while building it was to use it for device posture checks. Currently, alerts can be integrated with VPNs and proxies to allow or deny requests from devices that fail certain checks, but this requires manually parsing the webhooks. Over the next couple of years, I plan to focus on making those integrations easier and more seamless.
Edit: One major feature I’d like to explore is device identity and attestation using TPMs or secure enclaves. This could allow Checkpost to verify that requests are only coming from enrolled devices.
Currently further developing https://www.brickifyme.com, where i added a anon process for generating the images and running some A/B tests.
Also working on https://wk-pool.com to further develop it for not only World Cup predictions, but aiming to compete with Scorito in two years!
Codebook - https://github.com/0x007BA7/codebook
It’s a better code reader built on top of sem (treesitter). I’m getting a lot of massive PRs at work now, and this has helped a lot with reading them. It decomposes the changes into entities and sorts based on what has the most dependencies. This tends to put the most important functions first. Plus I can click through the dependencies for each function and mark things as reviewed as I’m reading them. It’s a big improvement over the GitHub review flow for me at least.
this looks incredibly useful! I've also run into similar problems with code review and been building similar tooling with the same idea (reconstructing the changes into entities, and finding focal/important changes), but haven't gone as far as this.
https://finbodhi.com — It's an app for your financial journey. It helps you track, understand, benchmark and plan your finances - with double-entry accounting. You own your financial data. It’s local-first, syncs across devices, and everything’s encrypted in transit (we do have your email for subscription tracking and analytics). Supports multiple-accounts (track as a family or even as an advisor), multi-currency, a custom sheet/calculator to operate on your accounts (calculate taxes etc) and much more. Supports price for most Indian investment vehicles and US stocks.
Most recently we added support for creating custom dashboards. You can compare return with leading/trailing/rolling charts for investment options and benchmark (create custom dashboards tracking nav and value chart of) your portfolio (or a subset of assets you own) and US stocks, etfs etc. And family dashboard (e.g. you can see networth, cashflows, income, use sheets at family level and more). See https://finbodhi.com/changelog for details.

I have a daily puzzle game called https://lettered.io and I’ve been playing around with shareable replay gifs via gifenc. It’s been fun trying to get good looking replays without sacrificing size for quality
The age of AI has been incredible for the daily game space because you can play around with ideas so much faster and riff to find something that works. On the flip side, there’s a lot more games that just rip off another idea and change some mechanic slightly to make it “new”
Building South Africa's version of TCGPlayer/Cardmarket/etc, for Yu-Gi-Oh! https://lekkerduelist.co.za
There's competition in the other TCGs, and of course a 2-sided marketplace is one of the hardest things to seed. So this is mostly just a project that I can put any fresh ideas into that I wouldn't be able to at my dayjob.
I got tired of Codex/Claude not being able to write good UI reliably, so I made a TypeScript library toolbox to help with that.
https://github.com/yuechen-li-dev/MachinaLayout.JS
Pretty much just SwiftUI-like layout/style in TypeScript with a bunch of utility tools from other languages I like, like Rust's payload enums, table helpers, LINQ-like queries, state management, etc. It's framework neutral so it works with React, React Native, and Vue right now. Everything is just plain TypeScript that compiles to the DOM, so no HTML or CSS needed for most normal web apps, they can all be written in plain .ts or tsx files.
1. A compiler for real-time tensor processing (arbitrary DSP, ML). In something like LISP or Haskell, the goal is to compile lambda calculus for fast/reliable execution—as such, you can express a program in a fully general language that can represent any computation and execute it without explicitly modeling the lower levels of the machine. I'm building a compiler that does the same thing for the subset of programs that are guaranteed to execute on-budget. The effect: you write code that looks like DSP/ML math and it compiles/runs optimally with execution guaranteed by construction.
2. My take on an agent framework ... append only log + content hypergraph in Elixir, tools that regularly pull data from other services into Postgres—built as a kind of 'exoskeleton' around claude/codex so it's not competing with fast-moving tools.

Some things I want other people to build:
- Indexing for Github
- All-in-one social media ingestion libraries for agents
- GOFAI-inspired knowledge / semantic / research graph stuff—I want to point agents at rules/structures for writing connected, verifiable statements
I built my own weather prediction / visualization app: https://wx.rsp.li (on-device temperature lapsing, on device interpolation modes, user-selectable aggregations, etc…). One of these days I should do a writeup.
I also asked Claude to build a photo gallery for me https://places.pascalspoerri.ch (HDR, map support, similar images)
Same as last month for once - optimizing how well agents can work with a new language [1]. I've been able to 2-3x success rate and drop total tokens for complex tasks significantly (though the initial syntax dump is rough - need to do some ablation there to get it down).
The best part has been that I think it's significantly improved things for humans too; it's weirdly satisfying to be able to measure improved ergonomics. Also, since a big pitch/theory was that the language should be ideal for agents as a result of the original nice things for humans it was designed for, it's a relief to be able actually measure a concrete lift.

I'm working on a nationwide US parcel dataset: https://www.kaggle.com/datasets/landrecordsus/us-parcel-laye....
It's mostly "public" data, but incumbent data vendors charge $90k+ for this data because it has to be acquired and aggregated from 3200+ US counties. This is a lot of work if you aren't using LLMs and agents to do much of the work for you.
I'm trying to make quality parcel data more accessible to everyone.
I'm working on https://topicle.com/ An alternative to Reddit that more aggressively polices bots, spam and astroturfing and has strong guardrails in place against bad moderation. No private profiles that bots use to hide, every mod action can be appealed, mod logs are public, LLM posts are blocked. There's so much obviously inauthentic activity and questionable moderation on Reddit, I decided to try addressing it.
https://buildthreads.com/
Aggregator for new posts in build threads from 277 old-school DIY forums.
Build threads of people building cars, 4x4s, motorcycles, boats, airplanes, hot rods, musical instruments, etc.
This is amazing! Very refreshing in the age of AI to see so much manual building going on. Sadly I don’t have much time myself but I have several friends who would love this, I’ll pass it on to them.
Thanks, that means a lot. I've found that browsing through a few dozen build threads is the perfect cure for the AI blues.
Ohh this is the type of stuff that interests me although I am not a car fan but I like what you are doing with the aggregation/old-school DIY forums.
Good luck with your build and perhaps I might get interested in future too as I did once have a thought that having a custom car to me would reflect more cool-ness than an expensive one. I am really interested by small cars, perhaps retro. I imagine my favourite car to be somewhat like the car that Ryan gosling drives in La La Land.
but a cool project nonetheless, certainly thinking about it inspires a bit of car enthusiasm within me even though I am not that much of a car fan so much right now so a really cool project if it can help more people feel this spirit. good luck :-D
I have a question but how does building new (retro-inspired?) cars go about in terms of pricing. I feel like they might be too costly to get custom-built and that If I really ever in my life go about doing this, I would prefer DIY but I still imagine that it might be too expensive or hard to make a car. Are there any go-to cars which are easy/recommended within this space and how does it compare off economically and what are the technical expertise that you require with this type of stuff?
Once again, I wish ya good luck in the project and would love to hear your answers for some of the questions I have!
Thanks; much appreciated. I picked up an endless list of new build interests in starting the site and exploring different niche forums. Turns out I really like wooden boat builds, cyclekarts, intricate custom knives, handmade violins, the list goes on...
You're right that getting a car custom-built is where the costs add up quickly; easily north of $50K. Most of the cost is labor, which is $0 if you do it yourself. Some of the projects are much easier than others. If you want to fall down a rabbit hole, look in the kit car and hot rod categories; lots of affordable and small builds in there. The Buick Riviera in La La Land is more of a resto-mod cruiser project, but the small/retro itch is exactly what the kit car category scratches. The first step is to find a forum where people are building the car you like, and start following related build threads. That's the majority of my social media intake these days.
I finally decided to put together a Sonos controller with the navigation I wanted and SMAPI servers for the live music archive, and all the grateful dead and phish shows. Thanks Claude! A PWA with tailscale and I have a controller that does what I want and works at home on an S1 system and at the beach on an S2 - seamlessly. Better than the "real" thing as far as I can tell.

I am working on this Review Flow. An extention for Cursor / VScode to enable IDE as first class for code reviews.
It came from a frustration that I needed to switch between the browser and the IDE to navigate through the code and leaving comments on Gitlab at the company.
So I thought it could useful to create something and let it be accessible to the public as open source.
link: https://github.com/LuyandaLia/reviewflow
In a nutshell, it accepts draft comments, which can be modified and submitted.
It auto configs the env for Python as it uses FastAPI for calls to Gitlab.
It's my initial attempt. Suggestions, reviews, contributions are invited.

I’ve been exploring what sort of agentic tooling to write for creative coding and realtime VFX. My second iteration just got released earlier this week (also open source): https://sxp.studio/apps/subz

I am building https://nexaflow.com - a customer support AI agent with built-in modules so small businesses need not buy 4-5 services to run a business. We ship with CRM, Ticketing, Appointment/Scheduler, Booking management system (for Small clinics, etc). Nexaflow agents can answer (and take action on) customer queries coming from Whatsapp, Email, Web (widget) and more.
Java Server Side Rendering Web Framework -- zero external runtime dependencies outside the web server layer -- https://github.com/vadimv/server-components The idea is to provide complete Java-centric modern web UI stack for building internal tools and admin panels.
Building a rootless, namespace powered (deeply stretching the definition of a container), on demand application workspace.
- Each component in a mini app in a heavily locked down container - Components are deployed and built in a web workspace, in the same workspace you can open a terminal and use your favourite coding agent to work on component code (each terminal is itself heavily sandboxes, has rw access only to the edited component code and users home dir) - Everything comes with heavy rbac and minimum permissions - Oh so much more
Explaining this well is hard, much like explaining to someone what Kubernetes or AWS does. This is at a level of what a sophisticated company infrastructure team would run, just as a workspace you can deploy for yourself easily and agents just build within that framework (I’m a cofounder of a infra/compute/datacenter startup and intimately familiar with this kind of complexity)
The main thesis is that Claw-style agents still feel like school projects, and that in the agentic era apps on demand will be more of a thing, and that the current systems weren’t built to deal with a whole new app built every few minutes.
May or may not end up as open source soon
I’m trying to build the best TTRPG chronicler: https://loracle.app
Everyone who plays D&D has experienced the moment where they forget key details about the collective story they’re building. From ‘hey it’s been a month, where are we?’ to ‘wait who was this crazy npc again?’, ai is excellent at transcribing, notetaking and building a knowledge graph of your fantasy world.
I’m still building mostly for myself by adding a ton of features I know my friends would want, but also think there’s some ‘there’ there.
The idea is simple: let Loracle record your sessions on discord or upload the raw audio of your sessions, then get a rich personal wiki and session notes you can interact with.
If you’re mid-campaign you can also upload session notes from plain text and it bootstraps a campaign wiki. Then future audio based sessions have a good base of npcs, quests, characters, etc to build off of.
At this stage I’d love feedback more than anything else. Happy to comp a lot of usage to HNers in return for some reports on how well it’s serving you. Email admin@loracle.app for anything and everything.
I've been working with coding agents for a few years and became increasingly frustrated by the way it pushes you towards a solution. So I built rubberduck (https://userubberduck.com/) - a way to control exactly what solution the agent ends up creating by mimicking a design conversation with a competent colleague where the agent explores the solution space together and forces you to make decisions. The final output is a consolidated design document of all the decisions you made. At least that was how it began. I've since built an implementation plan step where it figures out how to translate the design to code and execution where it actually builds it. All of this happens in a properly isolated environment (using gVisor under the hood). There are more features I want to build so on it goes I suppose.
I’m working on https://main-duck.com/ which simplifies converting your code to mcp. I plan to make this easy to integrate into CI so mcps can be updated easily. It’s hosted remotely and I’m very excited about where it’ll go.

I'm working on a collaborative post-apocalyptic fitness RPG. I wanted to build a game that lets you take over the real world, gets you off the couch, and has only positive multiplayer engagement. If you find or invite another player nearby, all your actions with them benefit you both.
It's for iPhone, and for the best experience, Apple Watch. It's very early, playable via TestFlight, and I would love feedback! There's a TestFlight link at: https://reverdure.yourstrategy.co

My original idea for this was to compile an Ansible-like playbook to a binary. I made a POC for it around 2020, and then it sat on the shelf. More recently I picked it up again following a more Terraform-like model. It compiles IaC to a binary with all dependencies included, standardized CLI options, autogenerated configs, optional visualization in the browser, and lots of other features.
To people who say just use Terraform: I do, a lot. But it still bothers me enough to try building something different.
I am building https://EasyAnalytica.com - single place for all your dashboards. It generates dashboards automatically from data without using ai. It supports getting data from google sheets, api's, url's etc. I have recently added support for gsc as data source and i plan to continue adding more in coming weeks.

I'm doing a personal research project into the technical maturity of ccTLDs. So far I've mostly been working with easily accessible public information, which I'm almost ready to publish, but the next phase is going to be trying to identify markers of stack complexity (provisioning etc) which is going to be tricky.

Slowly improving the UX on my SQL review/approval tool: https://github.com/kviklet/kviklet
Also finally closed the first real customer on it recently!
I want to get through a large chunk of the open issues the next few weeks and then spend some time building agentic capabilities for it. I believe a central place to configure database access for your dev team without having to share passwords and with sensible review policies should also help e.g. if claude needs to access production data to validate a premise.
Still have to figure out the right UX though not sure the agent should have the exact same review requirements that a human does. Maybe it needs to be configurable separately
I am playing around with creating a public domain repository for ebooks. https://babelnexus.com There are a few differences. It uses core collection theory and is selective. The name comes from the short story The Library of Babel by Jorge Luis Borges. Borges used Hexagonal Galleries for his library. I realized you could put anything into hexagonal galleries. It did not have to be books composed of random letters. I also saw that you could use different levels to group kinds of knowledge using the spiral staircase concept. I have added other concepts like reading trails and cortex maps. I learned that the hexagonal concept of Borges library matches with knowledge graphs with both nodes and edges. There is a lot of experimentation in what I am doing. It is an art project, a bit of philosophizing, a bit on the public domain and many other things.
I want fast answers to questions like:
"Why is Zoom lagging?"
"Is the issue my WiFi?"
"What's going on with the Internet?"
So, I built a local Mac utility that runs in the menubar to give at-a-glance visibility into live network and application issues. It's free (for typical uses), battery-efficient, and gives fast and reliable answers.

Note: this involves blockchain VMs. If that's a dealbreaker, feel free to skip. I get it.
I've spent 8 years working on RISC-V VMs for blockchains, recently also contributing to ZK VMs. Modern blockchain VMs are drastically more powerful, and I'm curious how far we can push them. I started porting real game logic to blockchain VMs, running game loop, physics simulation, collision detection, etc., on blockchain VMs. So far I have:
* Teeworlds to CKB-VM: https://xuejie.space/2026_06_16_teeworlds_on_ckb/
* One Hour One Life to CKB-VM: https://xuejie.space/2026_06_29_porting_one_hour_one_life_ga...
* A small ray tracer to Jolt ZK VM: https://xuejie.space/2026_07_10_cpp_ray_tracer_on_jolt_zk_vm...
Source is available for 2 of the 3, I need to clean up the OHOL one.
Some context: CKB-VM [1] is a RISC-V virtual machine I designed for Nervos starting in 2018. Jolt ZK VM [2] is a zero-knowledge virtual machine developed by a16z. Both execute RISC-V code, but due to different design, Jolt ZK VM is a much faster CPU than CKB-VM.
Technically this is a fun challenge. Many techniques I used resemble game development tricks from the 90s on game consoles: fixed point math, banked memory in ROMs, aggressively inlining tricks, etc. I want to push to see where the ceiling is. Right now I'm trying to get a Godot [3] + JoltPhysics [4] game loop running on Jolt ZK VM.
Happy to answer questions about the VM internals, the porting process, or anything in general.

It's a calculator for what an AI feature costs to serve. Cost per request, cost per month, which part of the bill is eating you (output tokens, usually). No signup, all the math is on the page. Any feedback is welcome.
https://terminai.app
I got sick of choosing between the efficiency of working in a terminal and the magic powers of using AI (and of copy-pasting between the two). So I created a hybrid: Terminai is a transparent wrapper for any terminal that provides on-demand access to a TUI coding agent of your choice just a hotkey away (with built-in MCP and CLI that gives the AI access to your terminal).
https://songformat.com
A text-based song format for generating music. I wanted to be able to create a song entirely using text, so I created a TOML-based format for doing so, and gave it most of the features you would find in a DAW. Since the format can be described in a SKILL file, AI can be used to write a song in this format, which can then be converted to audio.
Working on Morpheus, an experiment to improve tool usage over small llm like Qwen 30b by introducing JEPA (https://github.com/ichiriac/morpheus)
I started burning down the backlog of all the stuff I wanted to get to for side projects but never had time for (before LLMs):

- https://smacke.net/pipescript/lab/index.html?path=demo.ipynb -- magritter-like pipe / placeholder syntax for ipython / jupyter, again able to run purely in the browser
- https://smacke.net/pycograd/lab/index.html?path=pycograd_sim... -- pyccolo and pipescript-powered autograd, once again able to run purely in the browser since numpy has a wasm target (notice a theme here :) )

Project I've got in progress is a migration of the old DIKU mud engine from C to Rust and making a Moog Model D synth recreation in rust with a JS wrapper.
The slime art is nice. I watched it for a long time. It's neat how you can open any frame up as an image. The controls in the description didn't work though.
Those are some fine drinks
Still a small plattform for groups of gamers to share their library with each other and suggest and vote on games for a game night. I'm planning on a group finder feature where you can publicly search for others to play with you, currently it's more angled at existing groups.

I'm working on MedAngle, the world's first Agentic AI Super App for medical and dental school. You can think of it as literally everything one would need from day one of admission till graduation day as a doctor.
I myself am the first medical doctor and full stack engineer in the history of my country (250 million), graduated as a doctor at age 25, and we have over 100+ users [all of which are medical/dental students and doctors], 10s of billions of seconds studying smarter, hundreds of millions of questions solved, and more.
Our Super App has subsystems including MedGPT, MedAgent, Spaci (our own take on spaced repetition) and much more.
We're bootstrapped, and continuing to scale. If you are in medical school or know someone who is, please reach out!

I'm working on the finishing touches for a big new "Event Filters" feature for my Shopify app, Stages (https://getstages.com). The feature will let users set up rules to decide which orders should be imported into the app based on certain criteria like Shopify product names, collection names, order value, and so on. Users have been asking for it forever, and I'm planning on publishing it this week!
I'm also working on an update to ShopifySharp, the .NET package I maintain for Shopify's graphql and rest APIs. I need to regenerate the graphql types and the fluent query builders for the July 2026 API version that was just released, and I'm planning on some extra QoL improvements that I've run into while using the package over the last couple of months. I particularly want to add some F# QoL features, since I wrote the package in C# but use F# in all my personal projects. (https://github.com/nozzlegear/shopifysharp)

Working on Gaming Couch, a web-based local multiplayer party game platform. It's like a lovechild of Jackbox and Mario Party: https://gamingcouch.com
Just before the weekend I shipped a new mini-game called Pop It: Desert Island (https://gamingcouch.com/blog/pop-it-desert-island-launch). Launch went well: ~3,800 players from 56 countries over the weekend, and it immediately became the most played game on the platform.
It's a battle royale with an ocean/beach themed world, taking inspiration from Roblox, Mario Kart and others. The whole game is built in JavaScript (three.js for the 3D world) using a JS SDK I've been working on. It doubled as a test drive of the same SDK I want to launch for third-party developers, so anyone can build and ship a simple, fun multiplayer party game for the platform, ideally in a single weekend.
If you're a game dev, or aspiring to be one, and want to develop and ship your own party game check out this page https://gamingcouch.com/developers
The TL;DR of Gaming Couch:
- Free Early Access with +20 competitive mini-games.
- Players use their phones as controllers (gamepads work too).
- Completely web-based, no downloads or installs needed.
- Every game supports up to 8 players and is action-based, with quick ~1 minute rounds to keep a good pace. No language-based trivia or asynchronous (turn based) games.

I like the idea, the API looks really clean

Underpinning my current app is an e2ee local-first sync engine, basically it is a traditional client-server sync (encrypted logs + snapshots sequenced with integers). It sends bundles of Loro CRDT operations. I wrapped the client side in WASM to power the web app and the CLI and have started a swift wrapper to port to native iOS. Bundle size is 3MB/1.2MB g-zipped so pretty happy with it. I've realised that web encryption is kind of bs (at least not as "WE CAN NEVER ACCESS YOUR DATA" as some vendors state) if someone else is distributing the app.
Over the last week I have done a lot of performance work & data remodeling - CRDTs are interesting because you can let data fall through the gaps if you're not careful.
I have ADHD, and my calendar is a graveyard of things that were totally fine right up until they were on fire.
So about to release an iOS app that sends me early notifications about what to actually prepare, or do.

I'm working on better UI for my app AutoPTT [1]. It's probably going to look somewhat similar to Discord's settings, except I won't be using Electron. I refuse to use bloated stuff like that, so I'm going to keep using a pure C UI library [2].
Obviously this is going to take a bit more work but at least the resource usage will stay low, which I consider quite important. Especially since gamers are a large portion of the user base.

It’s an AI-powered mock technical interviewing platform, for system design and coding.
I’m also working now on behavioral mocks, with a coach feature!
I’ve been working on it on and off for a year, but started spending significant time in the last few months.
I know everyone’s burnt out on LLM products, but I think it’s nice for this kind of prep since you can do it on demand and in an environment it’s safe to fail as much as you need without judgement so you can actually learn.
It’s early and free if anyone is interested in trying it out (at least while I can afford to serve it for free)
I continue to work on version 2 of a product that’s been shipping for the last couple of years. I’m not linking to it, because the last thing it needs, is a bunch of folks registering single-use accounts, only to find it doesn’t interest them, but we need to wait a year, to delete the resource hog they registered.
Version 2 is a significant upgrade, and is a bottom-to-top rewrite of both the backend server, and frontend app.
I’ve been using an LLM extensively, and it’s been a huge help. I have, however, also run into its limitations.

Even so, keeping momentum is never a given and requires constant output from all angles! Onward...

Used Claude to write conformance tests for https://aep.dev.
https://github.com/thegagne/aep-conformance-test
Did pretty well, only took a day or so. I first had it inventory every MUST, SHOULD, and MAY in the spec, and then let it rip. I did guide it quite a bit to get what I wanted, but at the end I’m pretty happy with it as a first draft.
Helped me learn the spec and will be helpful to hone my dotnet AEP server, and aepbase.
There already existed an aep e2e validator which does a similar thing, but this is more thorough and generates a nice report. It will tell you not just whether your API follows the spec, but also what parts of the spec it does not implement.

Looking to experience life outside of software, but I don't know exactly what. In short, current filters are:
high total customer face to face time// high face to face time per customer// probably not in sales
as these are too abstract to map cleanly to traditional job board filters I’m scraping indeed and using deepseek to classify jobs according to this criteria, with an aim to discover really good jobs and then put a lot of effort into each of those jobs, like reaching out to hiring teams directly etc. works alright but worried coverage is an issue.
ps- can any one recommend a service or product that does this already? i should be able to set a city and then write my own filters like "this job involves dressing up like a crocodile" or "this job requires ballet dancer experience" and have each job posted in my city get assessed. maybe i get an email each day of matched and not matched jobs. i have tried to search myself but given there is so so so much slop in this space i find it very hard going. and most products do this just very poorly...

apt-cacher-ultra: To help reduce the impact of future DDoSes of Ubuntu. Just released 1.0 yesterday after working on it a couple months.
As that DDoS was going on I realized that some of our dev and staging processes were impacted by it, and that apt-cacher-ng was doing nothing to help us.
apt-cacher-ultra snapshots the repo meta-data after verifying it, and only promotes it if the metadata all checks out. Additionally, it can optionally keep a list of "hot" packages, and can include those in the snapshot calculation.
Additionally, apt-cacher-ng would regularly choke and require some handholding. I'm hoping -ultra resolves that as well.

Are you using the reddit api or scraping new reddit posts/replies?
Scraping. I applied for the token but never heard back. Reddit doesn't want new devs working on it.
Had the same experience with upwork, feels like the door has closed on easy api access to big site data, ironically funneling people's money to proxies and other scrape helpers instead of their own api.
Yeah, perhaps its due to noone wants LLMs trained on their data for free. I don't know, at least for reddit there are still ways to get the data for free.

For the life of me, I could never get electronics. I used to love the idea of me coming up with electronic circuit designs, but the arcane art of electronics never really clicked for me because I just couldn't intuitively grasp the maths no matter which book I read (AoE, I'm looking at you). But then it hit me, I don't need maths, I just need a formal language to represent the circuits. So over the past few weeks, I worked on a code your own spice (the electronic simulator). So now, for the first time in history, I finally understand how circuits work and how they are designed. And I did this all by coding circuits in python and making my own functional spice (which used to seem impossible at one point, it's surprising how easy it is though).

This month https://thingstohave.app, my calm and flexible wishlist app, reached a state I can call "feature complete". This iteration took two years of occasional work, so it's a big milestone for me. (I've posted updates on this app in previous threads)
Since the last update, I released everything that had been in testing since April, like gallery view, custom avatars, birthdays and, most importantly – autofill from link.
Now I'm preparing for a big launch – working on the landing page, SEO and onboarding experience. Here's what I've done so far:
1. I updated the landing page to actually tell users about the app and look presentable. I already see a big improvement in conversion
2. I added SEO crap to the landing page. This is painful for me, but sadly that's how Google Search works (it doesn't). It's paying off, too
3. I overhauled the onboarding experience, to make it smoother for new users
Two more features are still in testing; I plan to ship them before the release, but currently i'm not completely happy about them.

Code World Models in Simultaneous Move settings like Capital Markets. DeepMind's CWM approach relies on standard MCTS/IS-MCTS, which assumes a single active player at each node.
This doesn't work in simultaneous-move settings like Orbit Wars (or order-book markets), converging to an exploitable pure strategy rather than a Nash equilibrium.
LeCun's JEPA, by contrast, is a learned neural world model, which lacks the determinism, speed, and debuggability of a code-based simulator. Thus, it can drift or predict illegal states, and you can't inspect why it made a prediction the way you can trace a Python function.
TL;DR: The benefit is better auditability and easier RL-like training. The SM-MCTS extension fixes the first problem (decoupled UCB per player approximates Nash equilibrium instead of a pure strategy) while keeping the second advantage intact (a deterministic, inspectable code simulator).

I've been working on an LLM "harness" called Logbook[0] for fun with Codex.
The core idea was that I've always been a lousy notetaker, even going back to my school days years ago. I'm great at one-off and one-liner notes and occasionally more in-depth notes, but tend to not flesh them out fully enough to make them worth re-visiting.
This has been a struggle even as an engineer sitting in meetings or trying to absorb new information when starting a new job and ramping up.
Logbook is meant to use an interaction paradigm we as engineers are using very often these days: it's a terminal UI in the vein of Claude Code, OpenAI Codex, etc.
It's targeted at the entry of free-flowing thoughts but you can also write longer notes by launching your default shell editor from within the tool.
Each note is saved as markdown with some metadata and that metadata is then saved to a local SQLite DB.
For the LLM side, the tool extracts useful metadata from those notes and then performs some local ranking/categorization. It then has the ability to send a note or some metadata to a provider of your choosing (it's straightforward to use OpenAI or something more broad and customizable like OpenRouter) for further enrichment or filtering.
A couple examples of the currently implemented slash-commands: `/related` can be used to find related notes; say you've been scribbling down notes about OAuth or MCP servers and want to gather up the most relevant notes to one of those topics. Or you can use a `/gaps` command that'll help you find things you've taken notes about but without properly defining or providing context around them (i.e. you mention ID-JAG for OAuth but never actually say what ID-JAG is, this command will tell you this so you have a chance to review what you previously wrote and can then define exactly what that keyword is about).
It's still very much a work in progress. It's not meant to be a full-fledged note-taking app a la Obsidian or anything like that. I've just always preferred taking notes in markdown or plain text and this is a great way to continue doing that while also making enrichment of the notes pretty simple.
You may ask "why not just use agent memories?" I don't really like the idea of tightly coupling notes with codebases or agents and I don't find the current UX very intuitive at least for the way I prefer to take notes.

Working on a platform to create agents using prebuilt tools. Using it to learn more
I'm building Voxoria (https://voxoria.ai), it tracks whether B2B brands get mentioned when people ask ChatGPT/Perplexity/Gemini instead of Googling.
Ask the same engine the same question twice and you get different answers, different citations, sometimes a different opinion of your brand, so figuring out how best to present this has been a fun product problem to solve.
It also tries not to be yet another dashboard: instead of just analytics, an agent turns the findings into a ranked list of "ship this fix" todo items.
Curious, how fast the AI providers re-index a page after you make a change? Do you see the results in the next model update, or do they try to use more realtime data by making their agent fetching the website every time?

I see a lot of new (and, to be frank, a lot of mature ones) HR tools are just wrapping Chatgpt around resumes (almost like "OK, now match this resume against this job posting and tell me if applicant fits"), which introduces a massive bias/inference problem.
I decided to build the exact opposite – a deterministic, math-driven fitness engine. It extracts structured scorecards from both CVs and job requirements and mathematically matches them, so you can actually review the exact reasoning behind why a candidate scored a, say, 85%. This fitness value is specified at every interview step – as applicant goes through an interview process their scorecard is updated at all steps.
If anyone here builds in the HR space, I’d love your feedback.
If tools like this are popular then it sounds like it'll be impossible to switch domains.
Yes, and what's scary is that I can easily imagine HR departments loving these tools and using them at scale.

building a 90s style point and click 2d game called AshNOak that generates varied stories with 3 characters. Story beats are managed using opensource LLMs. still a WIP.
I've been climbing for a decade, but over the past 3 years I've put on a bunch of weight due to work and certain life events. But I want to change that.
I know what motivates me: seeing progress. The feedback loop of "do X, see Y gain" is what keeps me going.
So I started building an integrated dashboard that can aggregate data from multiple systems:
- My digital scale
- Apple Watch (sleep + running performance)
- Beastmaker Motherboard, which is an electronic board that you attach a hangboard to and it shows you various stats like how much force you're applying
The idea is that every morning I'll open the dashboard and be able to see exactly how much progress I've made the previous day: weight loss, strength gain, cardio performance.
It's an interesting problem. There's essentially two parts to it: Apple Health, which aggregates data from the scale and the Apple Watch and can POST-export it hourly, and the electronic board, which sends data via BLE in real time. The destination for both of these will probably be an always-on Raspberry Pi 5, but I haven't decided yet. Then I'll have a small server app that can pull the data from the Pi and draw some fancy charts.
I've been working on a similar concept (aggregate health data from multiple sources) but on a wider scale: 1) annual bloodwork as part of my annual preventive care; 2) InBody measurements, including grip strength; 3) quality of air in my region; 4) Apple Watch but mainly for steps, sleep data and resting heart rate; 5) allergy panel or minerals/vitamins screen plus something nutrition-related along those lines (TBD).
The idea is to see trends and try to apply AI for correlating, at the first glance, completely unrelated data layers. Example how I'm thinking about this one: there's somewhat clear correlation that I sleep better when I do above average steps per day. How is my sleep quality affected if, let's say, I did above avg steps with a bad air quality at that time? (i.e. wild fires / pollen season / etc.)
I've built a Go application to ingest those data sources and currently finishing my first import use case - Apple Watch data.

Lots of things.
- Got https://beachcomber.sh pretty much stable. Next stage is to propose to various upstreams its worth integrating. - Custom firmware for some ikea symfonisk dials because the oem firmware on them has some pretty bad bugs. Added features like hold and turn. Getting nice smooth dial behaviour over zigbee etc is surprisingly tricky - Built a skill evaluator tool that runs a skill through test suites and then tweaks the skill context and runs again. Its been pretty effective to be honest, almost all skills you do the first version is laughable compared to the one you get after this automated self improvement. - A robust tmux bridge interface for claude to hook into, and then a director layer on top of that for agent orchestration tooling - a stenographer skill that on the fly ripgrep and builds a rag on your on disk conversation history as a form of memory. Pretty effective. - I have just started a tool that brokers woodpecker ci to openbao/vault to give a gitlab like integration for controlled secrets injection for ci. - Been beating my head against a camera tool for a while now, finally making headway. Many ptz cameras dont support fov move, which nvrs need for ml object detection and tracking. They just have a super clunky continuous move and stop. So my tool characterises the camera with cv tools and calibrates movement curves to produce a data file that can be used by my onvif proxy to emulate the more advanced move commands. - Various helper tools for fusion, like csv based parameterised export, and compliant magnet insert generators. - A pipeline that consumes my content backlog, ie instagram saves, reddit saves, hn faves, etc and analyses them with local models and various algorithms steps to categorise and intuit why it was saved and what the key information is and what category it fits into for future reference etc. - A map of my city that shows live river height data with flood map overlays, contour data, predicted overland flow etc. flooding is a regular concern but theres no great resource to know whats going on. I have about 60gb of public datasets it works with. - A package manager for kicad library symbols and footprints, datasheets - skills for kicad so claude can reasonably interpret the schematic and advise on problems, check against datasheets etc. surprisingly effective. - A gcode controlled expansion board for the Carvera Air that gives you 8+8 channels of control for extraction, air assist, vacuum table, timelapse camera, etc. you only have 1 pwm pin so the protocol encodes over that. - A novel exploration interface for vitamins that renders them in a network graph, showing relationships. When you select one it rearranges around it into a kind of valance orbit style so you can explore chains of effect. Turns out, lots and lots of things relate to magnesium. - A comprehensive usb c pd board with 4s battery management. 3a or 8a depending on version.
