Tom 'spot' Callaway

Tom 'spot' Callaway does not currently possess any notable mutant powers.

However, he is currently the Fedora Engineering Manager.

He is currently serving a term on the Fedora Board.

He is also responsible for the Aurora SPARC Linux Project, which is a port of Fedora to SPARC.
He's worked for Red Hat since February 2001, and is worshipped by lemurs throughout the known universe.

You can email him at: tcallawa<AT>redhat.com
On IRC (freenode.net), he's "spot".

He also maintains a LOT of packages in Fedora. He used to keep a list here, but it was a pain to maintain. Pkgdb has this list: https://admin.fedoraproject.org/pkgdb/users/packages/spot?acls=owner&acls=commit (some things I only co-maintain, or are dead packages now)

He's currently leading the Fedora Packaging Committee, responsible for RPM Packaging Standards and Practices.

Due to an incredibly erratic and unpredictable schedule, he doesn't currently keep regular office hours in #fedora (or anywhere on IRC for that matter).

And last but not least, he's a Sponsor for new Contributors. Currently, he sponsors these fine people:

Chuck R. Anderson
