RubyPulse is a screencast site that publishes regular videos about different Ruby libraries. It's a month old so far and German Ruby developer Alex Peuchert has put out 9 episodes already. With a little support, perhaps Alex will be able to keep it going and become the pure Ruby equivalent of Ryan Bates!

Each RubyPulse episode is in Quicktime format and about 4 minutes long - each is also available in an iPod/iPhone tailored format. The nine episodes of RubyPulse so far include:

• FastRI - A look at the performance-focused alternative to the "ri" command line tool.
• Memoize - An overview of memoization in Ruby (the process of caching method responses for future use).
• Gibbler - An exploration of the Gibbler library, previously covered on Ruby Inside.
• Sketches - Sketches is a Ruby tool that lets you create and edit Ruby code in your favorite text editor while having it safely reloaded in IRB whenever the code is saved/updated.
• Ruby Version Manager - A look at the "makes it easy to run multiple Ruby implementations at once" tool, RVM.
• hijack - A look at hijack, a tool that provides an IRB session into an existing Ruby process.
• random_data - A library that provides random test data, including: names, addresses, dates, phone numbers, e-mail addresses, etc.
• wirble and colored - A look at a set of IRB enhancements. (Bonus: Check out our previous roundup of IRB stuff.)
• live_console - A look at a library that provides an IRB sesson to a process over a TCP or Unix socket connection. Unlike hijack, however, this has to be pre-arranged.

Alex has done a great job with these videos so far and while his strong German accent might put some off, he's very effective at demonstrating how to use the libraries he covers quickly.
