This is missing the most amazing tutorial of the lot, Michael Hartl's http://ruby.railstutorial.org/ http://ruby.railstutorial.org/. The tutorial itself is a great hands on experience. What really distinguishes it though is the authors embrace of open source. The entire tutorial is available completely FREE in HTML version. I wanted to encourage this forward thinking business model, so I paid for the full eBook/screencast bundle (of course completely DRM-free). The author continues tirelessly keeping the tutorial up to date with latest versions and security fixes, and also releases those free. The one exception was when he did a second edition. He offered a nice discount for the upgrade, but I was a bit miffed to see early promos matching the upgrade discount. Michael was such a star though, after seeing comments on Hacker News he emailed customers to put things right. He offered a special extra discount, but I was so bowled over by this customer service, and because I wanted to support his wonderful project that I did not take him up on the offer.
