I'm looking for a list of the largest technology companies in the U.S.
(should be based on revenue).  The larger the list the better, but it
should have at least 100 companies.  A global list would be acceptable
if around 100 or so of the companies are headquartered in the U.S.  A
list that only shows publically-traded companies would also be
acceptable.  The list should be fairly recent.
