One of my favourite examples is: http://citeseer.ist.psu.edu/hinze99functional.html Anyone who studies binomial heaps is struck by the similarity to binary arithmetic. What Hinze does is formalise that similarity so that binomial heaps and binary numbers are instances of the same type class. Very pretty. -- Dan ___ Haskell-Cafe mailing list Haskell-Cafe@haskell.org http://www.haskell.org/mailman/listinfo/haskell-cafe
[Haskell-cafe] Bathroom reading
I'm looking for cool but mind-bending examples of functional brilliance. Let us say, hypothetically, you had a bathroom without any reading material. And having read all the Dilbert and Garfield you could seriously stomach, decide you should educate yourself while on the job. :-) So you decide to print up some one-liner style programs into a little booklet. Something between credit-card and postcard sized, with a neat but mind-bending program on it. Don Stewart occasionally swoops in with some fixpoint malarkey to defuse heated discussions. I mean that kind of thing, but with a slightly wider scope than just fibs... Suggestions, please!

Here's a small puzzle: without using a Haskell interpreter, explain what the 'foo' function does. foo = filterM (const [True, False]) In case you aren't familiar, here's the definition of filterM: filterM :: (Monad m) = (a - m Bool) - [a] - m [a] filterM _ [] = return [] filterM p (x:xs) = do flg - p x ys - filterM p xs return (if flg then x:ys else ys) Cheers, Spencer Janssen ___ Haskell-Cafe mailing list Haskell-Cafe@haskell.org http://www.haskell.org/mailman/listinfo/haskell-cafe

Clearly, we need to actually put together such a book! I'm imagining something where you have two mostly blank facing pages, with the code by itself in the middle of the right page; then the next 2-4 pages devoted to a short discussion of the code, how it works, related issues and techniques, and a list of references. All featuring beautiful typography and fantastic writing, of course. =) -Brent ___ Haskell-Cafe mailing list Haskell-Cafe@haskell.org http://www.haskell.org/mailman/listinfo/haskell-cafe

I used to work in a print shop and we did a lot of work for art and architecture students who would do this kind of thing all the time. Fantastic little notebook-style gifts of images and blank pages and elegant typography. It's just a shame so many of them were terrible at spelling! :-P It shouldn't be too difficult to use LaTeX to this end. Once a document class has been hammered out you can offer a range of different booklets! The Evolution of a Haskell Programmer series would be a good place to start. Bring it to your next job interview to whip out when someone points to that bit on your CV and says, what's that?. Any skilled TeXers in the house?

Well, it wasn't completely idle chatter on my part, either! =) After spending the past year writing (and typesetting) a mathematics book in my spare time, I would consider myself an intermediate to advanced user of LaTeX, although I know much less about TeX itself than I would like (although I do intend to learn). Unfortunately, what with applying to grad school and other things, it probably wouldn't be wise for me to spearhead such a project at the moment, although I'd be excited about contributing. But I very well might pick it up at a later date if no one decides to run with it right now. -Brent ___ Haskell-Cafe mailing list Haskell-Cafe@haskell.org http://www.haskell.org/mailman/listinfo/haskell-cafe
