Defunct projects
A graveyard commemorating projects that I no longer work on, but have invested significant effort into in the past.
ExpLetter
A rough newsletter on what I've been learning: I've moved on to publishing on my slipbox instead, and couldn't be particularly bothered with the newsletter.
PressTest
A tertiary plugin to mock and test WP plugins after I shipped one too many bugs in EventPress. This was greatly influenced by reading The Pragmatic Programmer.
One of the highlights for me was that it generates stubs for all of WordPress automatically, and then conditionally includes them into a unit test, allowing for much greater test isolation.
EventPress
A Google Summer of Code project that added Event creation/support to WordPress and BuddyPress.
BuddyPress Custom Posts
A secondary plugin extending BuddyPress to make it easier to add any arbitrary post type. It was written directly for EventPress itself.
