Both are important. I replied to a comment about commutativity, so I focused on that.

Linux doesn’t have an official libc. Raw syscalls are its only official API.

It was about code in third-party apps, not in Windows code.

Popper is more methodology of science, while Kuhn is more protosociology of science. Kuhn’s book doesn’t refute Popper’s, even if he would have liked it to. I don’t know about the two others, but after reading about them briefly they seem a

AwesomeWM as well. It allows you to write your own tiling algorithms in Lua.

I agree with Rich Hickey here and I think this is a flaw of sum types compared to union types. If Option<T> was a union type, T would be a subtype of Option<T> and those changes wouldn't be breaking. When writing Rust, I fi

Yeah. I have no idea what those images have to do with the surrounding text. Even ignoring the context, they don’t demonstrate what the font actually looks like all that well. That and, as others mentioned, it being published on medium.com

I read it. I don't see your point. Sentinel values simply give you a very low performance ceiling that you can't optimise past. What I wrote only took me a couple minutes. It's far from optimal (but it already takes 2/3

When you have the length, you can unroll the loop, so that you e.g. do 4 iterations at a time. With NUL you can’t do that. Moreover, loop iteration can be done in parallel (instruction-level parallelism) with processing the content of the s

I've never had a computer which would work with the official ideologically-pure installer. Always had to use the non-free one. I'm glad this vote turned out the way it did.

The “ml” tag on lobste.rs is about SML and OCaml, not machine learning (which is under “ai”), while here it seems to be about both. I find the original lobste.rs classification more useful.

For inter-machine communication TLV binary formats are far superior. Simplicity of parsing, efficiency. Can't compete.

Garbage collectors, type systems, modules, polymorphic functions are not syntactic sugar. Asm also isn’t syntactic sugar, if only for the polymorphism (how many different CPU instructions are MOV in Asm again?); or just the fact that it’s

Rust is supposed to be a systems programming language. If writing basic data structures was an edge case in it, the language would be broken. Luckily, in my experience it isn’t (at least not in this way).

Even in C compiler will emit warnings for unhandled cases in switch statements as long as you don’t provide a default case (as you shouldn’t).

This thread is, predictably, another demonstration of conflating optimisation with being aware of performance. The presented transformation of code away from “clean” code had nothing to do with optimisation. In fact, it made the code more r

The Emacs info manual is also a gem. And the Emacs info mode is my favourite document viewer, which makes for a nice experience all around.

I think you're excessively hung up on the example of everything happening within a single team inside a single company or some such thing, when the author of the submission wrote about making a choice for themselves. You don't sta

Better for the others, but is it better for the scouts? Too often individuals are treated as drones obliged to work for a collective, which feels entitled to the work of the drones. From your perspective, they're not a good team mate.

To be pedantic, that’s provided by bash, not devfs. You wouldn’t be able to do it like this from e.g. a C program.

None of that screams workers rights, nor welfare of the common people. Quite the contrary. If Marx was living in the XXI-st century, he’d be writing about Chinese instead of English factories. In fact the lack of workers rights makes it mor
