- I maintain several Fedora packages. The stuff that influences your day-to-day life the most is probably tzdata and make. Another salient package that I feel responsible for (though not solely) is boost.
- The projects the upstream of which I am mostly involved with are ltrace and elfutils. I used to be involved with frysk before it died.
- I opened a couple odd projects of my own: cgt (callgraph tools), tzdiff (a diff tool for timezone files), and there's a whole bunch of weird and wonderful stuff over at github.
- I am employed by Red Hat, and maintain some of the above and more in the RHEL land.
