I have been confused more learning Haskell than learning any other language so far. I am convinced that the reason for this is that Haskell requires thought a lot earlier in the process than any other language I have learned, and it doesn’t let you keep your hands busy while you figure things out by typing a whole lot of worthless syntax.

Not only does Haskell require more thinking upfront; it also takes away a lot of the trivial little bits and pieces that let you continue to keep your hands busy and feel like you’re really doing quite a lot of stuff, like telling the computer how to iterate over a list or add some things up. With thought at a higher level, it forces me to just think about what the program is supposed to do, and just tell the computer to do that.

How am I supposed to feel like a l33t h4ck3r if I’m not typing furiously for hours on end?

Really I was just writing a post about Haskell to make a note about a few things to check out or remember:

  • yesod for writing web applications in Haskell.
  • cabal describes, and provides support for, Haskell packages.
  • Hackage is the central package archive for Haskell.
  • learnhaskell is guide on github to learning Haskell, with links to several courses in a recommended order.
  • Learn You a Haskell for Great Good! is, as the name suggests, a book for learning Haskell. It has amusing pictures, and that would be enough, but it is also well written (as best I can tell – I am not an editor or critic).

Fraser at work said that yesod is fairly heavyweight and requires a lot of up-front learning before being able to do much. This probably makes it a poor candidate while learning, particularly since it is just in my spare time. He mentioned two more lightweight frameworks:

@mwotton uses Scotty, and also mentioned MFlow, describing it as a “continuation-based thing, so you can write multi-transaction web code in a single function”. It sounds like something to check out once I’ve covered some basics.

Chris Allen linked Magma (algebra), “so you know what you’re doing in Haskell,” so I’d better check that out too.

There is a mailing list for people learning Haskell: Haskell-Beginners.
