I'm wondering whether ReactOS can exploit Claude et. al. to their fullest and "recreate" Windows 2000/95. I may donate some tokens for that cause.

I've used Claude to fix/reconstruct & build leaked Win2k3 on Linux with original toolchain via Wine. This approach included full gdi sources reconstruction. I just don't know what to do with this, it's kinda difficult to "wash" on this scale

That sounds like a terrifying legal minefield that they would not want to tread

Is it not safe to assume Window source code is not present in the LLM training data?

It is rare that I say this but, thanks MS! Arguably just as, if not more, important is the BASIC that they wrote. That was what they actually wanted to do. DOS just got them the contract with IBM. For decades MS was really a developer tools company with a side biz of writing operating systems and other misc software. They also open sourced that BASIC code too [1].

I dont think I've ever seen a commit that says "49 years ago". Damn.

It is wonderful how early years of modern computing was brilliant. We treated machines as they really are: machines. Performance, creativity, science..., all possible to make a 386 machine work. Nowadays is all about libraries, virtualization, [bad] code over [bad] code over [bad] code..., I dont like it.

For a very long while now, we had programmers who never understood any low level concepts at all . They have started with js or python, and never looked 'down'. There are no limits to monstrosities they will consider normal. Linus Torvalds, a few months ago, said something to this effect when discussing AI coding tools. That his (also, mine) generation was lucky to have started with low level stuff and managed to ret…

No one understands the whole stack. There is too much specialized information.

The day they would make Windows 2000 codebase open source (or source available) would be the day I could die happy (although I'd probably be long dead anyways by the time there's a glimmerof chance of it happening). What a beautiful, smooth-running operating system it was.

Wasn't there a 2000 source leak a while ago? I remember some exploits coming out after the leak.

Yes but it could not be legally used by anything.

Yet another case where text printed on paper outlived any digital storage.

Seems like it was never digitally stored in the first place, and the printed text was barely readable due to age. Not really a big win for paper.

One has to be pretty ignorant and dismissive to claim that this is not "a big win for paper".

First of all, that comment is weirdly out of place. The quality and longevity of paper is not the topic.

Secondly, there are fragments of paper with writing as old as 2,000 years.

Thirdly, paper you look at and see the writing. With digital documents, you need the technology to read the medium and then you need to know how the information was encoded onto the medium, before you even arrive at the same level with paper, where you can start to decide the actual writing.

Paper has brought us where we are today, and given us what we know about the past. Don't be so ignorant and dismissive.

How did they print it then, I wonder?

They had some old German guy with a big beard, and two interns, running some sort of big contraption that looked like a medieval torture instrument, and the interns would run and put letters in a row and then the old guy move a massive letter and in the end out came a bit of paper with source code on it.

Where can I buy this printer?
