We've been experimenting at my day-job with using the nix package manager to automate the fetching and building of dependencies, and also isolate them per project/revision. In the root of each project repository, we have a shell.n

This is not forced by Gentoo. My Gentoo installs have separate bin directories which is what I got by default.

Why return an owned string instead of a borrowed str slice? A substring can always be borrowed and should never require a heap allocation?

Aren't there symbols missing for the mid central vowels which are common in English? I.e. https://en.wikipedia.org/wiki/Mid_central_vowel . How do you write e.g. "learn" or "bird"? It seems to b

Besides for verifying that the compiled program works on the target, tests are also required to compile with PGO because you need to have a runtime example to optimize for.

To me it feels like Cyrillic cursive has at least as many differences from its printed counterparts as Latin has. For example, д is written like a g, б kind of like a d, т like an m. The last one is especially confusing because м also exist

It is not an entirely painfree experience, though. In some cases it is not a completely unwarranted question. For example, the snow and ice melted here yesterday, exposing gravel on asphalt which is borderline painful to run on directly. Al

What happened to C? It's the #5 top language and you never ruled it out but it is missing from the final list? It seems like a reasonable first language with simple operations and not much magic happening behind the scenes.

Yes, the three holes are very common in Sweden, the first time I even encountered covers without them was when moving abroad. However, a few years ago Ikea removed them in Sweden also, unfortunately. From what I've heard it's beca

NHE looks interesting, they seem to have modified all clients to make the host player teleport above the map. With the current protocol, it seems like it is impossible to achieve this without modifying the guest clients as well. And by modi

Heh, what a coincidence! Does XSP stand for anything?

Are you thinking of Theater mode that first appeared in Halo 3? Unfortunately it was slimmed down in later Halo games and it is rarely seen in other games at all, especially not console games.

I haven't tried this out, I wonder how well the Halo 1 net protocol works over a less reliable connection. I encounter issues as soon as I momentarily minimize the emulator and it does not recover without starting a new game. I wonder

Thanks, I was initially surprised that they were encrypted but I can speculate on a few potential reasons: - The Xbox was designed to be able to play online via Xbox Live (e.g. with Halo 2 that came out later in 2004), and they might have s

There is also 'doas' from the OpenBSD project. It's a replacement for 'sudo' with fewer features and a smaller codebase, with the aim of a smaller attack surface. https://en.m.wikipedia.org/wiki&#x2F

This is a good point, I updated the article to include a comparison where the naive method is only using standardized floating-point operations. When not using -funsafe-math-optimizations the compiler emits sqrtps followed by divps (sqrtps

I believe you are correct, thanks for pointing that out. clock_gettime gives us ns and I multiply it by 1000 which gives us ps. Not sure how I initially got it to be fs. Updated it now.
