The Wufoo embed below is the historical form for this site. If it stalls, email still works at john@johntwang.com, and I read issues on the public GitHub repos. LinkedIn is fine for longer introductions.

If you are writing about a class lab that cannot reach 192.168.1.1, include the router model and whether DHCP was reset. That saves a round trip. I do not need a full crash log for a gateway that will not load.

Talk invitations and old Three20 questions can use the same form. I keep the original project URLs on this domain, so you can link a specific archives entry instead of pasting the whole thread.
