A collection of small but useful functions I wrote over the years that might be worth sharing.

2D visualization of virtual memory, symbols and thread activity

A simple to-the-point syntax highlighting function written in PHP and using extended regular expressions

A simple chat in ~20 lines of PHP and ~50 lines of JavaScript. Doesn't need a database.

Minimal OpenCL program on Windows

Simple subpixel text rendering for OpenGL 4.5 using dual source blending to blend subpixels individually

OpenGL 4.5 UI rectangle drawing benchmark

A simple DynDNS server with an build in HTTP interface to update IPs

A small Linux command line utility to inspect the available headless EGL devices and their properties (EGL client extensions, EGL device extensions, EGL display extensions and OpenGL extensions).

A simple PHP function to send mails

A set of small microbenchmarks about searching substrings in lines (of large files). Just for fun, nothing serious.

A collection of STB style single header-file C libraries

My second Lisp interpreter (bytecode compiler and interpreter) written in GNU C

Simple command line utility to blur images

A small library and tool to plot 2D mathematical JavaScript functions in a canvas element with panning and zooming.

A set of small system call microbenchmarks. Just for fun, nothing serious.

A very simple utility to execute a command when a file changes
