Currently here are many of the open source projects I participate and develop on my website.

My main development time currently goes into completing Scientific Calculator Web UI which is on the brink of it's next release. Currently Scientific Calculator is used by other open projects such as Amahi (Read about Amahi) which is currently based on Fedora.

Since becoming a GNU/Linux user in 2004 I have contributed tens of thousands of lines of code across many FOSS projects including patches, bug submissions, and creating my own software.

Other major projects I love and have contributed code and docs to include: Openfire, Aptana, MEPIS Linux, LinuxQuestions.org, NSIS, PortableApps.com and many others (I'll edit this as I think of more).

My user is sag47 across many projects (not all). If citing contributions is necessary I can do that as well.

I have a small group of people that run Slackware that I installed here in Champaign and Urbana IL. Most of my time is spent building bicycles and doing support for my little community of Slackers that seem to be growing. Most of the new CSM students come through here for open bikes lol. and a few questions on the kernel. Do not think I could be much help.
except putting some links on my website.
rebuilt pulse audio and handed over to Robby workman did not want to maintain it.
