As someone who just knows Ruby, how would you recommend learning Crystal? Is there some knowledge of C that would help a lot in order to learn Crystal?

Rather than some knowledge of C the biggest initial gap would be to work with value types (stored in stack), using some mandatory type annotations and working with generics for containers like Arrays, Hashes, etc.

Any experience in a statically typed language could be useful: C, C#, Java.

But if you just want to have an experience learning Crystal itself it could help to fill the gaps in some areas to allow others with similar backgrounds.

Recently we published some introductory videos with the folks at Daily Drip:

And for more hardcore materials you can download the slides and code examples from the CodeCamp we hosted at San Francisco this past May:
