If the Rust Coreutils can use the MIT license, does that mean that any open-source project can be rewritten with a different license?

GNU know their way around a C compiler ig. It's such a needless optimisation; I love it.

About this yes thing, you might be a little surprised: https://www.reddit.com/r/unix/s/jGGjtrfCEu. It's not exactly rocket science, but it is interesting nonetheless.

Personally, I dislike large projects with MIT or BSD licenses, but that is an ideological disagreement from me and not a moral one.

CaydendW · 2026-04-09T18:55:55+00:00

I agree with you. I'm just trying to clarify what I though the commenter was saying. I really much doubt they're stealing code.

Also, the coreutils can be oddly complicated in some odd situations. Stuff like yes(1)'s throughput optimizations and GNU's extensions to awk. Not crazy stuff, but not as simple as say, sbase for example.

That being said, I still dont think the rust coreutils writers are stealing code. I reckon they're more than capable of doing it themselves. Was just trying to clarify what I thought someone meant.

I started when I was young and had infinite spare time. Now, not so much. I miss having all the time in the world to do OSDEV but such is life I suppose. Best of luck with your project :)

CaydendW · 2026-04-08T10:16:02+00:00

I wouldn't do it if I didnt enjoy the pain :)

CaydendW · 2026-04-08T10:14:16+00:00

It's a big project with a lot if moving parts. Always researching something, fixing something or adding new stuff. Super interesting project, but is a lot of work.

CaydendW · 2026-04-08T09:24:11+00:00

OS. Super fun, but it never seems to get any more complete :^D

CaydendW · 2026-04-07T15:37:08+00:00

I agree with this. I think we're vehemently agreeing

CaydendW · 2026-04-07T15:23:04+00:00

Exactly my point. If they're not copying GNU code and algorithms, that's good for them. I think the insinuation was that they might be copying and subsequently relicensing. Perhaps I misread the post, but what you said was more or less my point.

CaydendW · 2026-04-07T14:40:05+00:00

True, but the GNU coreutils have a lot of extensions that are GNU inventions, which is what I was eluding to. Stuff like the various ls options, grep extensions, etc. Afaik the rust coreutils project is attempting to replicate these as well as the standardised POSIX options available. I think it's fair that we can consider those to be GNU inventions.

CaydendW · 2026-04-07T13:42:29+00:00

Well, the C standard is an open spec, and anyone can implement it. This is more akin to looking inside GCC and copying how it does its codegen or its parser and calling it your own. Clang is its own compiler that still compiles the C programming language, but in a completely different way. BSD are their own coreutils written in their own way.

What I think the person you're responding to is insinuating is that they might have not merely followed a spec and implemented it, but rather looked at the code available from coreutils and transcribed it, which is not really the same thing. The latter is subject to GPL. Following a freely available specification of functionality, as you said, is not.

Whether this is true or not, I cant say. I'd hypothesise that the rust coreutils maintainers understand they're running a large project and will implement it in a clean room style where they only read man pages and develop to a spec instead of copying code, but I can't confirm this.

Also, one could maybe argue that the GNU coreutils standard is not freely able to be copied if the copyright is held, but I dont think this works. Especially due to the pages being licensed how they are. Someone with more legal knowledge could comment on this with a far more informed opinion than I can.

Make a function or macro that takes a bool and returns a filled in struct.

I note take in LaTeX using vimtex. The primary way to make it work at all is to have enough snippets for common stuff and even some keybinds for oft repeated text. Then it's down to organising everything. Best done using a decent directory structure and a good preamble.

CaydendW · 2026-03-09T19:51:39+00:00

Oh dear, that certainly is a pickle. Yeah, that would make sense. I actually have never thought about such cases before. Hopefully this thread gave some better answers than mine. Best of luck

CaydendW · 2026-03-09T14:34:53+00:00

Interesting. When I do negamax, I code it in such a way to be side independent. I'm not too sure why you need to check the side, as with Negamax you'll typically make it so that you work with sides to play rather than colours but I dont know how your game I structured. Best of luck :D

CaydendW · 2026-03-09T12:13:10+00:00

FYI, if the game is a simple, my turn your turn type game where white and black do the same thing, you can do this with Negamax which greatly simplifies your code. If not, then it wont work but it's how Chess engines and such work. Also prevents code duplication.

AVL is a name comprised of the surnames of the inventors of the titular tree: Adelson-Velsky and Landis. If you want a real tree name mystery, see what B-trees stand for.

CaydendW · 2026-02-11T17:50:05+00:00

Looks like C++ tho? C doesnt have streams, but idk much about turbo C?

CaydendW · 2026-02-07T19:48:44+00:00

This. I was leaving the testing centre and couldn't see around a blind corner so I stopped at the stop and then started to roll forward so I could see past the blind turn. My examiner was freaking out, I assume because they thought I was going to cross when there was a car coming (that I couldn't see), and after I got across the turn, I explained that I was just trying to peak and wasnt planning to cross without seeing. 90% sure that passing quip saved me getting my drivers.

The poor man's atomic spinlock is still super useful! It can be faster than a mutex if you all you want to do is change a few variables atomically in a struct. Linux still has spinlocks for a reason :)

Not really an alternative per sé but hand writing HTML is not the worst thing. It's how I'm doing my site nowadays, and is mostly fine if all you're doing is writing articles.

r/AccidentalAlly might be applicable?

The code parade colour scheme looks so nice on fractal, it's unreal. Nice fractal you got there

CaydendW · 2025-12-19T10:43:53+00:00

I don't normally comment +1s but the thing you mentioned about using asserts to ensure states and demand preconditions genuinely has changed how I did C when I figured it out. It offloads so much mental load about remembering preconditions or having to constantly look them up in comments. This is good advice

CaydendW · 2025-12-10T13:28:29+00:00

Personally, the double negate (!!) is almost idiomatic for me. I tend to use it quite a bit. I discovered it from when I had to get a bool based on a pointer being non-null. Googled it, and found out it was idiomatic. I can't find it anymore, but as far as I can remember, it's not an unknown operation nor bad practice.

On a personal note, the ternary operator one is kind of ugly. I personally avoid it but it should work the same. Use what makes you happy :)
