Hi there

I am a software engineer, and I've been contributing to open source projects for 20+ years. My open source repositories include:

  • Cliquetool: Multi-purpose tool written in Go for finding cliques within a graph, building dense groups from the cliques, and generating reports on the results.
  • ilibgo: Go library for reading, writing, and manipulating images with API loosely based on X11 API and utilizing any X11 BDF font for writing text. This is a Go port of my C library (listed below).
  • WebCalendar: PHP LAMP multi-user calendar with translations to over 25 languages and long history of support. I have had many code contributions to WebCalendar over the years and can only claim to have authored about half the code. There are also over 25 translations.
  • Java Calendar Tools: Java library for parsing and generating iCalendar (RFC 2445) data
  • k5nCal: Desktop calendar application written in Java
  • GTimer: Linux GTK application for timing how much time you spend on various projects
  • Ilib: C library for reading, writing, and manipulating images with API loosely based on X11 API and utilizing any X11 BDF font for writing text
  • CVE services: I've contributed to the (new in 2021) REST API for MITRE's CVE project while I worked at MITRE. My primary contributions have related to containerizing the NodeJS app.

I'm currently working on:

  • Updating WebCalendar's UI to use Bootstrap and jQuery. It was previously using some very old custom HTML/CSS and a mix of JS tools (Prototype.js and others). The work for this is now in the main branch.
  • Teaching myself Go. I recently posted my first Go code on Github with my new cliquetool project. The project deals with cliques in a sparsely populated undirected graph based on some work I did years ago in C. My example data set includes be a list of NCAA basketball games from a single season. The goal was to determine the conference affiliations for all teams based on the list of games. (Note that in college basketball, each team within a conference generally plays each other team at least once. This is not true in college football where teams often play a subset of the other teams within their conference.)

Interesting facts:

  • My first open source contribution was a system menubar for HP-UX, SunOS, AIX and OSF/1 that I released in 1995 called xapplaunch (still online here) by placing the source code on a public FTP server. Note that the term "open source" was not actually established until a few years later in 1998.
