Hello, I put together a new (free online) book titled Best of Practicing Ruby (Book Edition) @ the Yuki & Moto Press Bookshelf that collects the best articles from the practicing ruby series headed by Gregory Brown with guest chapters by Luke Francl, Magnus Holm, Aaron Patterson, Solomon White and others. Topics include: A minimal HTTP server - Event loops demystified - Parsing JSON the hard way - Tricks for working with text and files - Working with binary file formats - and much more. Happy hacking. Happy reading. Cheers.
