Widely regarded as the language of the web, Ruby’s always been pretty damn hawt. But now it’s about to get even hotter. AltRubies have been pushing Ruby into realms we never thought possible.

Railscasts Alternatives

As many of you might know, I LOVE Railscasts – and like many of you, I miss Ryan heaps. He has a knack of being able to make things look super easy; his screen casts enable you to learn a great deal in just a few minutes. I often joke that it is a bit like the Matrix – we look something up, then we know kung fu! Rails Kung Fu of course!

I don’t know about you, but my Rails learning has taken a severe dip since Ryan has been away (I hope you are ok Ryan!!) though, it has also tied in with some personal problems as well, which has left little time for learning anything to be honest.

But the time has come to get back into it, and I hope to put together a list of Railscasts alternatives to tie us over till Ryan comes back. If you can think of any that you feel should be included, please leave a note in the comments to let me know. (more…)
