C, just in time

  1. 1CA

    CJIT started as a hobby project around Fabrice Bellard’s tinyCC and slowly grew into something much more practical. It is now a small portable C compiler and runner that works across Linux, macOS, and Windows, can self host, and is packaged as a single executable. What mattered most to me was keeping the barrier to entry low. You can take one small binary, drop it onto a system, and compile or run C code using the libraries already available there, without setting up a full toolchain or installing a large stack of dependencies. I find that useful for quick prototyping, testing, auditing,…

    I made a simple virtual machine that runs C in the browser.This project is made as an experiment to see if C can be learned easier if the lower level is covered in paralel.

    Hi HN, I'm the author. I built this project for two simple reasons: I've always used higher-level languages and wanted to finally understand what's happening "under the hood" of an interpreter. I also wanted a real project to force me to "power up" my C skills, especially with manual memory management and reference counting. The result is ToyForth, a minimal interpreter for a Forth-like language, written from scratch in C, stack-based. I focused on making the code clean and understandable. It's broken down into a few simple parts: A parser that turns source text into a list of objects…

    C Systems Lab is a free interactive web course that walks through 10 modules of systems programming in C: compilation, pointers, dynamic memory, structs, the preprocessor, file I/O, processes and signals, sockets, concurrency, and a tour below C. The free course itself is the link. Get the free sample of the PDF by adding "/demo" to the link. Since I don't necessarily like the paywall aspect of it, you may ask me for the complete edition by reaching out via email. Happy to answer questions about the content or the curriculum design.

    Hi, I work on this library because I like the simplicity of CGI and enjoy building things with C++. It is based on asio and my own implementation of FastCGI, and it works on both Linux and Windows. I have just released the new version and created a simple live demo that you can check out here: https://asyncgi-guestbook.eelnet.org

    hey guys, i wanted to show one of my side projects. The idea is a coding harness (independent of models) natively designed for C/C++ developer workflows. I'm a C++ dev and do not find claude code work well with C++ toolchain like gdb and perf. The current version has integrations for gdb, clang-tidy, cppcheck, sanitizers, perf, benchmarking, compile DB navigation, Godbolt, symbolization, binary inspection, and decompilation. It supports Anthropic, OpenAI, Gemini, and self-hosted models. There are editor workflows for VS Code, CLion, emacs, neovim, and cursor.

    I participated in the Nvidia + Vercel 2 hour hackathon in SF tonight, and built something I've wanted, but hadn't tried building. I implemented an MCP Server and VS Code extension to allow Claude Desktop to place breakpoints, step through code, and execute expressions (assuming language support). So you can ask it a question that requires actually stepping through the code and now it can actually do that - check values for you, etc. It's _definitely_ not perfect. Have improvements? Please make a PR!
