It appears that John Gruber has managed to crash his iPhone already. The crash log, captured on the way through his Mac to Apple, contains what looks to my eye as something a little ominous:
Exception Codes: 0x8badf00d
Now that is not the sort of thing to happen by chance. Furthermore the crash log doesn't seem to want to actually allocate blame for the crash to any particular thread or cause. Repeat after me: never buy the first iteration of an Apple product.
Lots of other interesting stuff in there too - binary images for an OpenGL-ES implementation, sqlite3 and frameworks called "CoreSurface" and "CoreTelephony". Hmmmmm.
Previous next big things include development of the capture and intermediate compression technology in iShowU-HD; design and implementation of a small advertising network; the refinancing, technical direction, and a lot of the donkey work for Virtual Katy; technical direction, project management and (again) donkey work for VoiceQ; creating code and intellectual property around load balancing that was acquired by Allied Telesis; and the research and an implementation of the h.264 video compression protocol.
