Great talk, but was expecting more rants about phpdbg :P
Sorry, but the talk was too boring and .. it was like being back in a classroom. I almost feel bad for not taking notes for the exam.
One of the best talks in all the conference. I miss advanced/low level stuff of this type. Great speaker, but next time he should prepare a little more how PHP deals with the memory :P
I like practical presentations like this. The demo was really interesting, and more explicit in showing how other people debug, test and profile, than a plain presentation. Good work!
