Exascale and Colin Luther Powell

Today is, according to my friend Simple Joe from Sin Sin At Ty o HI o, National Exascale day. You can follow Joe in his daily podcast by going to The Simple Joe dot com.  I listen to my friend Joe every day, and you should, too. Today is also the day that we say goodbye to Colin Powell Soldier, politician, diplomat, statesman, and four-star general, the 65th United States Secretary of State, the 16th United States National Security Advisor, and the 12th Chairman of the Joint Chiefs of Staff.
