    Project mention: How to convert an enum to string in C++ | news.ycombinator.com | 2023-09-30

    There are also other approaches. Macro variants making use of `__VA_ARGS__` would be probably the best trade-off. If you want a slightly more ergonomic syntax, something like Metalang99 [1] will help (and the author even wrote a post about this exact subject [2]). Codegen is another option which may work better than other options depending on the situation and exact implementation strategy. And there is always the Reflection TS [3], which may or may not be incorporated to C++26...

  • minicoro

    Single header stackful cross-platform coroutine library in pure C.

    Project mention: How Much Memory Do You Need to Run 1M Concurrent Tasks? | news.ycombinator.com | 2023-05-21

    It would be interesting to bench something extremely lightweight (like https://github.com/edubart/minicoro) against these runtimes.

    By my back-of-the-napkin math, 1,000,000 coroutines would cost about 64mb + 2mb/core for stacks.. which works out to about 4x less memory than the 'winner' of this comparison, and ~30x less than go.

    Project mention: How do crypto functions deal with the issue of character size? (e.g. Unicode) | /r/cryptography | 2023-06-18

    Hey guys. If you remember me from several months ago, with this object de art, I am here with a less cringy question than that of 'I made a hash function!!!111'. I apologize if this question is basic btw. My question is, how do crypto functions, of any kind, deal with character size? For example in C, wchar_t is either 2 or 4 bytes. So, if the implementation goes through the stream like stream++ it will be stepping word-wise not byte-wise. And then if another machine, using a different implementation, reads the stream byte-wise and not word-wise, then it won't get the same message right?

  • c-flags

    Library for parsing command line arguments easily. Like golang flag module.

  • cp437.h

    Project mention: Possible security issues allowing multibyte chars? | /r/C_Programming | 2023-02-23

    Dwarf Fortress Tilesets are CP437, and libtcod has a CP437 mode, and we even easily map them to Unicode with cp437.h.
