このCコードをpopcnt 1命令にコンパイルするのは難しくないか？ と思うかもしれないけど、実は場合によってはできる（godbolt.org/z/6ncKaq1df）。推論ではなくハードコードされたパターンマッチで変換してる。 そういう単純化のルールをLLMで自動生成できたら嬉しいというのはわかる。
Game engines should be designed so that creating empty textures is never necessary. Solving the problem is much better than encouraging a workaround.
This is what goes wrong when your wrapper library assumes no one would make syscalls directly on a platform that guarantees doing so works correctly. glibc has too many design flaws. Operating systems & programs should be working to remove any dependency on it whatsoever.
While researching the getpid() syscall for my daily series, I ran into an interesting piece of history. This goes back directly to the discussion from yesterday: should the OS offer a raw syscall interface or offer libc as the only contract? Here's what can go wrong!

It's crazy how inviting the reactor pools are. Something about seeing that blue glow with your own eyes, it's like a nuclear siren. Seems very comfy.
I was curious whether compilers would convert a naive loop implementation of "set range of bits in u64 to 1" into O(1) bitwise ops. Answer: MSVC compiles the loop into a loop. Clang's output is bonkers: 418 bytes long, branches everywhere, 256-bit SIMD operations get involved?!
Good post. A underemphasized benefit of SIMD is that so much of the cost of running an instruction on a modern ISA is fixed (decode, rename, register access, speculative execution) whether we're adding two u8s or two 512-bit registers with 64 u8s each. The gap is so large it ...
Android failing at trivial input handling on a 2200MHz processor + dedicated GPU. Comments believe this is because the HW is somehow not powerful enough
what I dislike about autocomplete is that i will want to use the arrow keys to navigate the text, but autocomplete will briefly make the arrows do something else, where I have to hit ESC, and the feeling is like doing parkour over random barriers
I think many software developers don't understand the concept of pipelining. If you're doing one thing that has Y steps, it makes sense to do one step at a time: go from step 0 to step Y and be done. If you're doing N things that each have Y steps, it makes sense to do the
