Henning Brauer is 26 years old and runs an ISP in Hamburg, Germany.
He is an OpenBSD committer since 2002 and works on all kinds of stuff
in OpenBSD, including the packet filter pf, the network stack, and
userland applications. Henning also started OpenBGPD and OpenNTPD.
When not hacking he likes to enjoy brewer's art or to go for a mountain
bike ride, of course only because mountainbiking helps to squash bugs.
