When the Ruby on Rails framework was first introduced a few years ago, nothing helped put it on the map more than the now famous “Creating a weblog in 15 minutes” screencast. In it, Rails originator David Heinemeier Hansson created a blogging engine using Rails in just 15 minutes. That demonstration was so powerful that it helped launch Rails into a major framework in the web development world, one for which programmers remain in demand for high paying jobs.
The demonstration was such a hit, that a number of other web frameworks emulated the Rails screencast and released their own versions. Akelos, CakePHP, CodeIgniter and others have released screencasts inspired by the original Rails video.
Recently, Hansson’s influential screencast received an update for Rails 2.2. The new screencast was produced by Ryan Bates of Railscasts, which puts out free Rails tutorial screencasts every week. In addition to the better production values that Bates brings, the new screencast has been ratcheted up a few notches by creating a blogging application that include commenting, RSS feeds, an API, an admin interface, AJAX, and more in just 15 minutes.
The new screencast might actually be a bit too fast and cram in too much information for it to be very useful as a learning aid (of course, that really depends on how fast you synthesize information and your individual learning style). But it definitely raises the bar in terms of showing the beauty of the Rails framework in a quick and easy to digest format.
The official screencast page also links the two previous Rails blog screencasts, created for version 0.5 and 1.0 of the framework, for those interested in seeing how the framework has changed over the year.
