My personal projects are on Github, as cjquines.
TeX—Style files and source files for my articles written in LaTeX.
Python—A library for writing programming problems, with some utilities for running programming contests. Most of my work was making sure it worked on Windows, small bug fixes, and documentation.
C++—A timetabling program, written for a high school project, meant to schedule classes the way they typically work in Philippine high schools.
Visual Basic .NET—A Windows program for keeping track of scores and times for a Mathcounts-style Countdown Round.
C++, Python—A repository with some of my solutions for competitive programming problems; mostly for my own use. Not really updated regularly, as I don’t do contests any more.
