Visual C++ 6 was the first C(++) compiler I used. I'm fairly certain it had auto completion (Intellisense).
Casey Muratori would point out the debugger ran faster on hardware from the era than modern versions run on today's hardware, though I don't have a link to the side–by–side video comparison.
Edit: Casey Muratori showing off the speed of visual studio 6 on a Pentium something after ranting about it: Jump to 36:08 in https://youtu.be/GC-0tCy4P1U — earlier section of the video is how it is today (or when the video was made)
It's really ironic that this appeared on the front page when it did, because I've spent the last couple days replacing the ZQuake sound system with FMOD and Atmoky TrueSpatial for HRTF and such. This was my first time ever working on a code base from 1996-2000. And in pure C no less. C feels so foreign to me since I'm so used to writing in C++ and Zig and such. But it was still really fun!
And I mean it doesn't seem super impressive, but it's something. Lol
On one particular project from 1995 where the hardware was very cost optimised, the C program compiled to 1800 bytes which meant we could save nearly a dollar by buying micro-controllers with 2KB flash rather than 4KB flash. We manufactured 20,000 units with this cheaper chip. 2 years down the line we needed a simple code change to increase the UART baud rate to the host, a change that should have resulted in the same sized binary, but instead increased it to 2300 bytes due to a newer C compiler. We ended up tweaking the assembly file and running an assembler, then praying there would be no more changes!
I have always over specified the micro-controllers a little from that point, and kept a copy of the original dev environment, luckily all my projects are now EOL as I am retired.
Correct, I have thousands of tank temperature controllers still out there, still working fine where the End Of Life was 3 years ago. EOL just means support for spares and software updates cannot be guaranteed past that point, and is mainly tied to the EOL of the specific micro-controller used.
Whilst I disapprove of your use of the word "just", which I am strongly of the opinion should be banned in engineering circles...
I have done something similar, albeit in a different context, to fix the behaviour of a poorly performing SQL query embedded in a binary for which the source code was not easily available (as in: it turned out that the version in source control wasn't the version running in production and it would have been quite a lot of work to reverse engineer the production version and retrofit its changes back to the source - and, yes, this is as bad as you think it is).
When I initially suggesting monkey patching the binary there was all manner of screaming and objections from my colleagues but they were eventually forced to concede that it was the pragmatic and sensible thing to do.
Build environment archaeology like this matters more than people realize. Modern CI assumes containers solve reproducibility, but compiler version differences, libc variants, and even CPU instruction sets can silently change binary output. The detail about needing to reinstall Windows NT just to add a second CPU shows how tightly coupled OS and hardware were — there was no abstraction layer pretending otherwise. Exact toolchain reproduction isn't nostalgia; it's the only way to validate that a specific binary came from specific source.

In this case there was: the reason you need to reinstall to go from uniprocessor to SMP was because NT shipped with two HALs (Hardware Abstarction Layer): one supporting just a single processor, and one supporting more than one.
The SMP one had all the code for things like CPU synchronization and interrupt routing, while the UP one did not.
If they'd packed everything into one HAL, single-processor systems would have to take the performance hit of all the synchronization code even though it wasn't necessary. Memory usage would be higher too. I expect that you probably could run the SMP HAL on a UP system (unless Microsoft put extra code in to make it not let you), but you wouldn't really want to do that, as it would be slower and require more RAM.
So it wasn't that those abstraction layers didn't exist back then. It was that abstraction layers can be expensive. This is still true today, of course, but we have the cycles and memory to spare, more or less, which was very much not the case then.
> If they'd packed everything into one HAL, single-processor systems would have to take the performance hit of all the synchronization code even though it wasn't necessary. Memory usage would be higher too.
Linux also used to be like this, but these days has unified MP/UP kernels; on single-CPU systems (or if you give nosmp), the extra code is patched away at boot time. It wouldn't have been an unheard of technique at the time.
I actually would love this to be built in to a language/compiler. A lot of times when I’m building a single-threaded program but I’m using libraries written by other people. These libraries don’t know whether they are being incorporated into programs with single thread or not. So they either take the performance penalty of assuming multi-threaded (the approach by std::shared_ptr) or they give callers choice by making two implementations (Rust Arc and Rc). But the latter doesn’t actually work because this needs to be a global setting, not just a decision made at a local call site. It won’t work if such a library is a transitive dependency.
They could have shipped both HALs. Or made it easy to switch which one was in use without reinstalling.
CDs were around and hard drives weren’t that small at the time. (Or maybe the really early SMP versions predated widespread availability of CD-ROMs, but I remember dealing with this nonsense and reinstalling from an MSDN CD set.)
With NT4, I'm pretty sure both HALs were on the CD-ROM (unless you had an exotic system with a custom HAL, which came with its own install media). Keep in mind your use case is approximately nobody, you either had a SMP system or you didn't.
It was really not that rare to want to move a disk from one system to another. Except that there was an obnoxiously high chance that Windows would refuse to boot.
there is something to be said about old windows installation CDs being essentially modern-day equivalents of immutable docker layers - i don't think one could say that about modern windows, but then i'm not super clued in into ms stuff.
> The first batches of Quake executables, quake.exe and vquake.exe were programmed on HP 712-60 running NeXT and cross-compiled with DJGPP running on a DEC Alpha server 2100A.
Is that accurate? I thought DJGPP only ran on and for PC compatible x86. ID had Alpha for things like running qbps and light and vis (these took for--ever to run, so the alpha SMP was really useful), but for building the actual DOS binaries, surely this was DJGPP on x86 PC?
Was DJGPP able to run on Alpha for cross compilation? I'm skeptical, but I could be wrong.
I thought the same thing. There wouldn't be a huge advantage to cross-compiling in this instance since the target platform can happily run the compiler?
Running your builds on a much larger, higher performance server — using a real, decent, stable multi-user OS with proper networking — is a huge advantage.
Yes, but the gains may be lost in the logistics of shipping the build binary back to the PC for actual execution.
An incremental build of C (not C++) code is pretty fast, and was pretty fast back then too.
In q1source.zip this article links to is only 198k lines spread across 384 files. The largest file is 3391 lines. Though the linked q1source.zip is QW and WinQuake, so not exactly the DJGPP build. (quote the README: "The original dos version of Quake should also be buildable from these
sources, but we didn't bother trying").
It's just not that big a codebase, even by 1990s standards. It was written by just a small team of amazing coders.
I mean correct me if you have actual data to prove me wrong, but my memory at the time is that build times were really not a problem. C is just really fast to build. Even back in, was it 1997, when the source code was found laying around on an ftp server or something: https://www.wired.com/1997/01/hackers-hack-crack-steal-quake...
> (Visual Studio 6) I never used it but it must have felt like a dream at the time.
I used it in the mid-90's and yes, it was eye opening. On the other hand, I was an Emacs user in uni, and by studying a bit the history of Emacs (especially Lucid Emacs) I came to understand that the concepts in Visual Studio were nothing new.
On the third hand, I hated customizing Emacs, which did not have "batteries included" for things like "jump to definition", not to mention a package manager. So the only times in the late-90s I got all the power of modern IDEs was when I was doing something that needed Windows and Visual Studio.
I've only played Quake I (and a modified version of it at that which had accessibility features).

I doubt that everything you ever worked on is end-of-life. Some of it is still out there...

Better have kept those environments.
Could also just edit the old binary directly in a pinch?

Quake book incoming from Fabien?
Almost certainly - every other of his books has been telegraphed by articles about the work he’s doing to get the original setup built and running.
I hope so. The other books have been great fun to read, with the detour of CP-SYSTEM as a nice surprise.

Zig supports this. If you compile with -fsingle-threaded, operations on mutexes turn into nops, atomics become simple loads/stores, etc.
Linux also used to have separate SMP kernels back when multi processor systems were rare.
I’m pretty sure that the SMP kernel would boot on UP and vice versa, though.
They could have shipped both HALs. Or made it easy to switch which one was in use without reinstalling.

I'd like to see someone build the Linux source code leak that came out not to far after Quake was released.
What do you mean, "leak"? Linux would have been developed in the open?
I think OP means leak of linux quake port source
I think they are referring to the 1997 hack/leak: https://www.wired.com/1997/01/hackers-hack-crack-steal-quake...

Funny, I've just been (re-)playing Quake 2 recently.
Action Quake II is still the best I’ve ever been at FPS.
Yes, such a good game! :)
Gonna warm that up when the kids get a bit older and we start doing LAN parties.
That and Quake World Team Fortress.
I'd kind of forgotten about AQ2. I wonder if I can get that going.
I bet there are still servers out there, at that.
Nod. AQ2 was so damn fun!!
