Let's build an MP3 decoder, stepping through the MP3 decoding processes a bit at a time, with source code. Via Brainwagon.
Learn You a Haskell for Great Good! I don't understand Haskell, I'm not sure when I'd use it, it also looks like the absolute antithesis of objects, which I've found to be very useful, but I suppose that's a reason I should learn a little bit more about it.

I think the thing about Haskell is that it's functional, which means, every function is side-effect free and you get functional composition (I also think it has lazy evaluation). I've never played around with it, but I have played around with Erlang, and ... functional languages require a different mindset, that's for sure. No loops (so you best feel comfortable with tail recursion), variables are single assignment (so you best feel comfortable with tail recursion) and you don't really use 'if' statements (conditionals are tested against a pattern).
Another thing about Haskell, because of it's functional nature, I/O isn't allowed, since it causes side effects. To get around this, Haskell has "monads," which nobody seems to really understand, but act as a type of "world state that can change but don't look too hard because it's not pure" thing.
We will not edit your comments. However, we may delete your comments, or cause them to be hidden behind another link, if we feel they detract from the conversation. Commercial plugs are fine, if they are relevant to the conversation, and if you don't try to pretend to be a consumer. Annoying endorsements will be deleted if you're lucky, if you're not a whole bunch of people smarter and more articulate than you will ridicule you, and we will leave such ridicule in place.
