My answer to Is there a way to learn Ruby in one hour? on Quora
Not unless you already know a bunch of other languages and are well versed in programming language theory. Even then, that might be long enough to get your head around Ruby syntax and semantics but it will still take weeks or months of study to get truly comfortable with the language idioms.
If you aren’t already an experienced programmer, no.
