    Project mention: Are there any weaker hashes than MD5, but still randomly distributed? | reddit.com/r/learnprogramming | 2022-01-28

    wyhash is a decent option for if you don't need a cryptographical quality hash

  • clifm

    The shell-like, command line terminal file manager: simple, fast, extensible, and lightweight as hell

    Project mention: Ideas for features of a tui file-manager | reddit.com/r/commandline | 2022-04-29

    What you are describing looks a lot like clifm

  • lizard

    Lizard (formerly LZ5) is an efficient compressor with very fast decompression. It achieves compression ratio that is comparable to zip/zlib and zstd/brotli (at low and medium compression levels) at decompression speed of 1000 MB/s and faster. (by inikep)

    Project mention: Lizard | news.ycombinator.com | 2021-11-08
  • hob3l

    100x Faster Slicing of SCAD Files for 3D Printing

  • beebjit

    A very fast BBC Micro emulator.

    Project mention: MHz 6502 | news.ycombinator.com | 2021-10-13

    I was wondering how quick an emulated 6502 could go. This project claims 10GHz+ using JIT emulation: https://github.com/scarybeasts/beebjit

  • Scout APM

    Less time debugging, more time building. Scout APM allows you to find and fix performance issues with no hassle. Now with error monitoring and external services monitoring, Scout is a developer's best friend when it comes to application development.

  • stricks

    Managed C strings library

    Project mention: Buffet | news.ycombinator.com | 2022-03-07

    > I was thinking about Simple Dynamic Strings but I like this better.

    Oh! here's my chance to plug https://github.com/alcover/stricks ! It follows the same principle as SDS (i.e user-facing type is char*) but is much faster (see bench) and frankly nicer to read through.

    Not as feature complete, though.

  • jobflow

    runs stuff in parallel (like GNU parallel, but much faster and memory-efficient)

    Project mention: Autodocumenting Makefiles | news.ycombinator.com | 2022-01-31

    Another part I think might be parallel execution, running multiple shells at the same time


  • Description

    Mini async log C port. Now with C++ wrappers.

  • cgif

    GIF encoder written in C

    Project mention: CGIF - GIF encoder written in ~600 lines of C | reddit.com/r/programming | 2021-11-15

  • FastHamming

    Fast implementation for truncateable extended (127,120) Hamming codes

    Project mention: Error detection and correction on PIC microcontroller | reddit.com/r/ECE | 2021-11-02

    Check out https://github.com/BenBE/FastHamming (AGPL license). It should work for all blocks that are a multiple of 15 bytes, I haven't tested all other sizes.
