Advanced Ruby: a 2nd-level course. If you have already done some Ruby programming, this course will help to take your coding to the next level. It explains some of the more advanced features of Ruby including blocks and procs, threads, regular expressions, exception handling, singletons and metaprogramming. The course is based on Huw Collingbourne's book, The Book Of Ruby (a copy of 3rd PDF edition of the book is supplied with this course). All the source code is provided in the code archive. This course can be used with any editor or IDE and on any operating system that supports Ruby. If you are ready to go beyond the basics and gain a deeper understanding of how Ruby really works, this course is for you.
