Programming and Performance with Cliff Click

A weekly podcast with Cliff Click talking about all things to do with programming, programmers and computer performance.

I'm teaching a class this summer; the website is here: Rocket Realtime School of Programming and Performance This podcast contains a short introduction, and a few minutes spent on the material to be covered in the first few classes: understanding the low-level hardware to help you write higher performing code, and a look at Virtual Machines with a deep dive into the JVM.  

Thinking about language design - see https://github.com/cliffclick/aa for the start of an implementation. RocketRealtime.com is real!  Please visit and sign up! And survey results are in!  Due to overwhelmingly positive response, I am please to announce the Rocket Realtime School of Programming and Performance, with classes starting sometime this summer or fall.  I am frantically trying to get a website for the school together even as I type this.
