*Erin provided a list of unique SubSkills and TracedSkills with frequencies, as well as a python script to normalize the skill values in the challenge sets.
*Vikram gave a presentation on Hadoop, EC2 and MapReduce. He created a bunch of scripts for EC2 MapReduce. Those tools can be found on [http://github.com/voberoi/hadoop-mrutils github].

Here are some map reduce notes:

Word Counts (let line number be the key):

1 hello how are you

2 how is it going

3 are you happy

<pre>def map(key, value):

words = value.split()

#["hello", "how", "are", "you"]

for word in words

emit(word, 1)

def reduce(key, values):

emit(key, len(values)) </pre>

results:

hello [1]

how [1,1]

are [1,1]
