Hi, I'm Abhay Kumar. I like to throw up interesting things I encounter here. You can also see the result of my mustache pact with my coworkers, check out what I'm up to or see the few photos I take. I like to receive email and instant messages (AIM / Jabber), as well. Some links of interest: Calais Text Tagger, Powerset
For some reason I was looking up my company and found this Ruby function for finding the power set of an array. I compacted it a bit more:
class Array
def powerset
inject([[]]){|c,y|c.inject([]){|r,i|r+=[i,i+[y]]}}
end
end
