    Git GUI Client

    Many Git client apps have some problems. It's too late to start up, falls well, is user registration tedious when downloading, is paid for commercial use, is not multi-platform, or is an animation or visual effect. It was said that the production was overkill and the wizard and the source code were not published. I tried to eliminate such inconvenience as much as possible. At first I started developing it for my own study, because I was interested in learning how to use Git and how it worked...

    Wrangling Untrusted File Formats Safely

    ...The design prioritizes predictable performance: decoders avoid dynamic allocation by default, return explicit “short read” signals, and run well in streaming or sandbox-free environments. The project ships battle-tested, CPU-friendly implementations for common image/container formats and bit-twiddly primitives like Huffman and checksum routines. Its standard library emphasizes portability and constant-time behavior where appropriate, which is valuable in security-sensitive contexts. Because the language is purpose-built, the resulting C output is small, auditable, and easy to embed in larger systems.

    A tiny little JSON parsing library

    sj.h is a tiny JSON parsing library written in C99 for developers who want a minimal, allocation-free way to walk through JSON data. It is intentionally small, around a few hundred lines or less depending on how it is counted, and keeps state minimal so it can fit into constrained environments. The library does not try to own every part of JSON handling; instead, it leaves number conversion and string interpretation to the user. This design gives developers direct control over memory, numeric precision, Unicode handling, and application-specific parsing behavior. ...

    Oboe

    Oboe is a C++ library that makes it easy to build high-performance

    ...It abstracts device and API-version differences so developers can focus on audio processing instead of platform quirks. The library emphasizes minimal latency and glitch-free playback/recording via tuned buffer strategies and callback-driven I/O. It supports features like floating-point audio, channel configuration, sample-rate negotiation, and stream sharing to match device capabilities. Example apps and utilities demonstrate best practices for thread priority, audio mixing, and underrun handling. By aligning with the native audio stack, oboe enables professional music apps, real-time communications, and games to achieve consistent audio performance across a wide range of devices.

    Checked C is an extension to C that lets programmers write C code

    Checked C is an extension to C that lets programmers write C code that is guaranteed by the compiler to be type-safe. The goal is to let people easily make their existing C code type-safe and eliminate entire classes of errors. Checked C does not address use-after-free errors. Checked C adds static and dynamic checking to C to detect or prevent common programming errors such as buffer overruns and out-of-bounds memory accesses. The goal of the project is to improve systems programming by making fundamental improvements to C. This repo contains sample code, the extension specification, and test code. ...
