Online Coding and CS courses

In a comparison of seven (eight, actually) of the current crop of online dev schools, Chris McConnell at DailyTeckk notes the topics available for study (Web dev, programming), languages used (mostly Python and JavaScript) and costs (free to monthly subscription):

• Treehouse
• Codecademy
• Udacity
• Mozilla's School of Webcraft
• MIT
• Khan Academy
• Google Code University
• Code School

Two more notable sites I've found:

• Learn (Python | Ruby | C | [X] ) The Hard Way
• Ruby On Rails Tutorial

Edit: Steampunk Nancy Wu notes a couple of other sites in her survey of the online learning landscape:

• Coursera
• CodeLesson
