Bei O’Reilly gibt es einen Auszug aus dem Buch Learning Rails.

Dort wird auch Heroku erwähnt:

Heroku is a completely novel approach to deploying web applications. Forget about servers; the fundamental unit is the app. Use the Heroku client gem to create and manage apps from the command line. Then deploy your code with Git, and control the running app with the remote Ruby console and rake commands.

Ach, die Rails Welt scheint auch sehr spannend zu sein.

(update)
Ich sehe gerade es gibt noch weitere Auszüge:
An Incredibly Brief Guide to Regular Expressions, A Catalog of Helper Methods und An Incredibly Brief Introduction to Relational Databases.

Das O’Reilly Buch Praxiswissen Ruby on Rails (pdf 4mb) gibt es als kostenloses pdf.

deployment environment. It comprises a library agnostic set of tools for any type of browser based JavaScript development, which coincidentally has Gears support.

Frizione provides local JSLint checking of your JavaScript code.

Frizione provides joining (concatenation) of JavaScript files to produce unique libraries.

Frizione uses the YUICompressor to reduce your JavaScript code to the bone.

Frizione provides a two stage unit testing framework, using your JavaScript code and a minimum framework to run the tests, which are stored to hard disk in JSON format. The results can then be displayed using a second unit test viewer page.
