Tyler Brock for Five Stars - 2011

Write function f in python, that given a list of numbers
L returns i, j such that L[i:j] has maximal sum.

For example, if L = [1, -2, 3, 4, 5, -1] then f(L) should return (2, 5).

OS Setup
- Install VMs (base OS = Ubuntu 11.04)
     - 6GB disk is not enough.  Probably 20-40GB would be good.  Mongo has a lot of compression and cleanup features coming.
- Create user to run MongoDB as
- Get DNS or Hosts file set up so all nodes in the cluster can talk to each other
- Generate ssh-keygen -t rsa
- Copy ssh public keys from each node to node01.  Then cat all keys to authorized_keys.  Then copy that file to each node.  Each node will have ssh key trust now.  You will also want to ssh from node01 to 02,03,04; from node02 to 01,03,04 etc to test it out.
- Create an initial architecture:
node01: master (replica set 1)
node02: slave  (replica set 1)
