In the neverending stream of interview that comes out of the Zend Developer Zone, Cal Evans is back with notes from his talk with Jeremy Johnstone, a speaker at this year's OSCON.

I had nothing on Jeremy, all I knew was that he was speaking at OSCON and he worked at Yahoo. As it turns out, it was a very interesting interview. Not for the normal reasons though. If you want more, you’ll have to come inside and read the interview.

Well, I'll cheat a bit and tell you some of the topics they talked about such as:

• Jeremey's experience and background
• his experience at Yahoo!
• some of the work he's done there (including the Address Book application)
• Yahoo!'s move to PHP 5
• everyone's favorite topic - "disaster recovery"
