Lee Hinman writes S-expressions for Sonian all day. Feel free to email me at lee [at] writequit [dot] org. If you do contact me, I highly recommend that you use some sort of encryption.
I enjoy doing software development, security research and writing tools and libraries (mostly in Clojure or Ruby).
I want to point out the excellent baseline firewall rules posted by rmogull over on his blog. Check them out if you’re looking for a starting point for ipfw rules on OSX. Thanks rmogull!
