A real HTTP 2.0 effort: HTTP/2 is a replacement for how HTTP is expressed “on the wire.” It is not a ground-up rewrite of the protocol; HTTP methods, status codes and semantics will be the same, and it should be possible to use the same APIs as HTTP/1.x (possibly with some small additions) to represent the protocol. The focus of the protocol is on performance; specifically, end-user perceived latency, network and server resource usage.
Rasmus Lerdorf, the inventor of the programming language PHP, came to Cal Poly yesterday to give a two-hour lecture on PHP and related web technologies. I didn’t know anything about him, but I was pleased to find he’s a very intelligent, pragmatic, and humorous person. He spoke at length about the transition of PHP into an open source project, the evolution of the language, and some security and performance topics that I found very interesting.
