Today I’m announcing the release of Ruby 1.9, What you need to know a two part Envycast staring David A. Black, one of my favorite Ruby authors/teachers. Each envycast is available for $9 or you can get both as a package for just $16 dollars. To make things a little sweeter, you also get 40% off David’s new book The Well-Grounded Rubyist with your purchase.
