How Ruby Manages Memory and Garbage Collection

Garbage Collection and the Ruby Heap is a presentation given by Joe Damato and Aman Gupta at the recent LA Ruby Conference. You only get the slides for now (all 70 of them!), but they're very detailed and can almost work as a standalone concise e-book on Ruby's garbage collection system.

Joe and Aman take a look at C memory management vs Ruby and show the difference between the stack and the heap. As a garbage collected language, Ruby takes the easy route by putting everything on the heap and the presentation demonstrates how the MRI (Matz's Ruby 1.8) does this, as well as how objects are tracked within memory (right down to the underlying C structs).
