Factor IIRC:

    1) 10 [1,b] [ 2 * ] map
    2) 1000 [1,b] sum
    3) { "scala" "akka" "play framework" "sbt" "typesafe" }
       "This is an example tweet talking about scala and sbt."
       '[ _ subseq? ] map
    4) "data.txt" utf8 file-lines
    5) 4 [1,b] [ 3 = [ "you" print ] [ "dear" print ] if ] each
    6) { 49 58 76 82 88 90 } [ 60 > ] partition
    7) "http://search.twitter.com/search.atom?&q=scala" http-get string>xml
    8) 100000 sieve :)
