This article presents a branchless Quicksort implementation using sorting networks and discusses how modern compilers, especially Clang, optimize loops with branch-free instructions when written in the right style.
colibri is a pure C inference tool that runs the GLM-5.2 744B MoE model on ~25 GB RAM by streaming experts from disk, eliminating the need for expensive GPUs.
Colibrì is a pure C inference engine that runs the 744B GLM-5.2 MoE model on consumer hardware with ~25GB RAM by streaming experts from disk, achieving ~2.2-2.8 tokens/second with speculative decoding.
An excerpt from the tiny-c Reference Manual, describing the origins, design philosophy, and features of the tiny-c programming language, which combines elements of BASIC, LOGO, and C in a simple, integrated environment.
The article announces the results of the 2015 Underhanded C Contest, a programming contest focused on writing deceptively malicious C code, with this year's challenge involving nuclear verification and highlighting NaN poisoning attacks.
CParseC is a single-header C99 library for parser combinators inspired by Haskell's Parsec, offering zero-copy parsing, no hidden allocations, and SIMD-optimized combinators. It aims to provide a flexible, performant alternative to handwritten parsers and lex/yacc tools.
Compares Qwen3.6 27B running locally against Opus 4.8, and highlights a voxel engine built in raw C with zero frameworks.
A minimal CPU-only inference engine for Qwen 3 models implemented from scratch in pure C.
This article delves into the differences between C in the Linux kernel and ordinary userspace C, covering core techniques such as resource management, error handling, concurrency, logging, static analysis, and extensively using GNU C extensions and kernel-specific patterns.
The Linux kernel has finally removed the dangerous strncpy function after six years and over 360 patches, replacing it with safer alternatives like strscpy that guarantee NULL-termination.
A CLI tool called ffs that searches files by reading the disk directly, bypassing the OS kernel's VFS layer, offering potential speed advantages over tools like ripgrep for large, uncached directories. Supports ext4, btrfs, and APFS file systems.
Fil-C introduces memory-safe inline assembly, ensuring that programmer errors result in panics or traps rather than miscompilation.
Explains the use of GCC's computed goto extension to improve the performance of bytecode VM dispatch tables compared to traditional switch statements, with a simple example.
Nordstjernen is a secure, minimal web browser written entirely in C from scratch, focused on HTML/CSS standards compliance and process-per-tab sandboxing. Version 1.0.8 has been released as a maintenance update.
A senior developer used Visual Studio 6 from 1997 and pure C to build a dual-stick shooter game framework on Windows 7, demonstrating retro development practices such as fixed timestep, object management, and OpenGL compatibility mode.
A humorous educational article covering C programming fundamentals such as forward declarations, operator precedence, unconditional jumps, and basic arithmetic with intentionally silly code examples.
The lead developer of the Kefir C compiler announces the cessation of public development, moving the project to private mode indefinitely to preserve personal enjoyment and sustainability.
The article explains the confusing behavior of C array types, including their decay to pointers, exceptions like sizeof and function parameters, and compares it to function types, suggesting a mental model where arrays and pointers are strictly separated.
A blog post updating the classic survey of C constructs that don't work in C++, covering changes in C++20 and C23 standards that affect compatibility.
An article explaining the historical and technical reasons for the existence of the arrow operator (->) in the C programming language.
