Programming in Haskell
Not really a review, just a strong recommendation… Graham Hutton’s Programming in Haskell is published mid January 2007, but Cambridge University Press are shipping already — I got mine just before Christmas and wish I had it earlier… It is by far the best introduction to Haskell I’ve seen, at least for someone new to functional programming such as myself. The chapters on parsing and and IO are a good mark of the book, together clearly yet stealthily introducing monadic programming in an easily digestible form. Well this book has plenty of other aspects I could praise, but like I say this isn’t a review, just go read and enjoy it yourself.
It’s great to read a really clear, concise text book, I could almost feel my brain re-organising itself while I read it. The experience reminded me of reading K & R after some months of confused C hacking, feeling everything clicking into place. That would be over ten years ago now, gah…
Peano curve weaves of whole songs
Some nine months ago I played with weaving images from music, including using a peano curve as a mapping.
I’ve returned to this subject, having many good ideas to explore from recent discussions with Tim Blackwell. We thought rendering some whole songs would work nicely. I didn’t fancy playing with my Java code again so wrote some Haskell, which I’m rather pleased with. The source is available (feedback welcome!). It does the the mapping using seeks on the output file, allowing impressive memory efficiency via Haskell’s lazy evaluation.
Some examples of some indie synth pop, disco, minimal techno (*3) and industrial gabba below, click on the images for the full versions but beware, they are rather large, around 5M each. Mouseover for the original track names.
