Visualizing Garbage Collection in Ruby and Python
This is a post that Pat Shaughnessy wrote based on his presentation at RuPy in Budapest. You can also watch the video recording of the presentation. This recap was originally published on his personal blog, and we're republishing it on Codeship with his kind permission. If your algorithms and business logicare the brain of your application, whichorgan would the garbage collector be? Since this is

Rare Are GC Talks
This article is meant to be an easy to understand explanation of GC algorithms to those who think to themselves "I get that garbage collection is useful, but I don’t really understand how it all works". An explanation of how the CRuby*1 GC works will follow. Finally we’ll look a little at recent studies on Ruby GC alternatives. Oh, just to set the record straight, the GC described in this article

Ruby 2.0 Garbage Collection
There’s been a lot of talk about the improvements in Ruby 2.0’s Garbage Collection performance. That’s a great thing, because GC in older versions of Ruby wasn’t very performant. Most of the conversation about generational GC (or other strategies) revolves around making Ruby GC more efficient. This has a great impact on your users, because less GC time means that their pages return faster.

Incremental GC in Firefox 16!
Firefox 16 will be the first version to support incremental garbage collection. This is a major feature, over a year in the making, that makes Firefox smoother and less laggy. With incremental GC, Firefox responds more quickly to mouse clicks and key presses. Animations and games will also draw more smoothly. The basic purpose of the garbage collector is to collect memory that JavaScript programs
