Cal Evans has posted another interview, this time with George Schlossnagle. They discuss George's background, a little bit of OmniTI history, and some of George's opinions about PHP and scalability.
When asked which technology has him most excited, George mentions DTrace by Bryan Cantrill (and Adam and Mike). Speaking of DTrace, Apple announced at WWDC this week that it's going to come with Mac OS X Leopard. Sweet!
