Yes, I'm the /dev/random guy as well as the ext4 guy. I've also been the serial driver guy, and the tty guy (Posix job control was my first large contribution to Linux). I also was on the board of the FSG when we hired Jim Zemlin, and when the FSG merged with the OSDL to form the Linux Foundation. I was the Kerberos v5 TL at MIT, and I served as one of the IPSEC working group chairs and on the IETF Security Area Directorate. Oh, and for a while I was Treasurer for Usenix.

See? There are plenty of ways to be a technical leader without being on the management track. :-)
