hakunin / New to Datamapper

Created December 25, 2009 15:55

	Few things to keep in mind when starting with Datamapper.

	1. new records cannot be user in hashes

	h = { Record.new => 1, Record.new => 2}
	h.values # [2]


	2. dm has associations

hakunin / czech twitter - pagerank after 10 days datamining

Created January 3, 2010 19:23

	Popularita českých osobností na Twitteru
	========================================

	Jakou metodiku jsem zvolil
	--------------------------

	Pro nalezení autorit jsem zvolil Pagerank algoritmus (http://en.wikipedia.org/wiki/PageRank).
	K jeho správné funkci je třeba sestrojit orientovaný graf s vrcholy = autoritami a orientovanými
	hranami ve směru kdo na koho odkazuje.

hakunin / Pascal's triangle.hs

Created February 10, 2010 21:02

	-- This is how Haskell newb (me) writes Pascal's triangle

	-- evolution of each row

	pascal [1] = [1, 1]
	pascal (x:xs) = pascal2 (x:xs) [1]

	pascal2 (x:y:xs) o \| xs == [] = (1:(x+y):o)
	\| otherwise = pascal2 (y:xs) ((x+y):o)
