Open source software stuff

I'm not going to bother describing the exact relationship between me and these projects. Sometimes I'm the only author, sometimes a co-author, sometimes I'm a mentor, sometimes I sent one patch a gazillion years ago.

  • Apache TripleSoup, the simplest thing that you can do to turn your apache web server into a SPARQL endpoint.
  • Apache Excalibur, stable and mature open source java framework for "component-oriented programming" using inversion of control
  • Apache Gump, python-based continuous integration server on steroids
  • Apache Incubator, IP clearing house and community education center for new projects entering the ASF
  • Apache Harmony, J2SE implementation in development at Apache
  • Picocontainer, powerful little "dependency injection" java framework
  • Jicarilla Software Development open source packages, a bunch of software I've either written or patches or repackaged while working for clients, and open sourced afterwards. Of particular note is my devenv package which is a cross-platform java/python source tree which is nice to use as the basis for Really Big Projects That Need To Just Build.
  • Jicarilla Wiki, interesting tidbits, articles and papers from a period where I thought a lot about java and java frameworks and the like
  • Jicarilla Project, large amounts of clean, documented, tested but totally unused java code, like another "inversion of control" "lightweight" "dependency injection" "container", a pure java HTTP 1.1 parser and webserver using asynchronous IO, and a variety of utilities
  • MoinMoin source @ the ASF, customized version of MoinMoin which powers the Apache Wiki
  • APWorkflow, unused and abandoned beginnings of a python-based CGI application for managing a variety of infrastructural tasks at the ASF

Non-open source software stuff

Just a small selection. You don't care about this anyway. Most of the stuff I do these days seems to be completely covered by a very fat NDA.

  • Joost is a peer-to-peer-based video platform. I currently work there, doing a 101 different things (for example, I try to help maintain the opensource @ joost page).
  • WADI, one of the "commercial" projects I worked on (its for the Dutch government) where I'm actually allowed to say so
  • @Semantics, my main client when I was freelancing, is where I helped with WADI

Old website stuff

Just a small selection. You don't care about this anyway. If you do, An archived version of leosimons.com also has an archive with yet more stuff in it.
