Over in PostgreSQLand ... Tom Lane is an important member of the PostgreSQL core team and also was involved in the PNG image format (and other graphics related efforts).
Something that came as a surprise to me was the fact that QEMU and FFMpeg are made by the same guy as well.
Kind of depressing; either one of those projects has that person set for life in the job market, and that jerk has both! How am I supposed to compete with that?
EDIT: Just a note, I say this with all the love in the world, and certainly wish no ill-will towards Fabrice. I hope my dumb joke above didn't come off as hostile...I think it's pretty cool that one person was able to build two apps that I use daily.
