   A Ghidra extension for exporting parts of a program as object files▲304

   This Ghidra extension unrelocates machine code through analysis and then synthesizes a working object file from a listing selection. It effectively turns computer programs into Lego bricks, to be torn down into pieces and reused into something new. It supports the COFF and ELF object file formats, for the x86 and MIPS architectures. It has been successfully used on Linux, Windows and PlayStation executables. One user report is on a commercial video game from 2009 with a ~7 MiB Windows executable written in C++: it was delinked without its C runtime library and then relinked into a new…

    Header-only GIF decoder in pure C – no malloc, easy to use▲47

    I built a lightweight GIF decoder in pure C, ideal for embedded or performance-critical environments. It’s header-only, zero dynamic memory allocations, and fully platform-independent. Supports both static and animated GIFs, with turbo and safe decoding modes. Works great on microcontrollers, IoT devices, and anything with a framebuffer. Would love feedback or ideas where this could be useful. Github: https://github.com/Ferki-git-creator/TurboStitchGIF-HeaderOn...

    Copy-and-patch compiler for hard real-time Python▲65

    I built Copapy as an experiment: Can Python be used for hard real-time systems? Instead of an interpreter or JIT, Copapy builds a computation graph by tracing Python code and uses a custom copy-and-patch compiler. The result is very fast native code with no GC, no syscalls, and no memory allocations at runtime. The copy-and-patch compiler currently supports x86_64 as well as 32- and 64-bit ARM. It comes as small Python package with no other dependencies - no cross-compiler, nothing except Python. The current focus is on robotics and control systems in general. This project is early but…
