FILE - In this Oct. 25, 2006 file photo, Sun Microsystems CEO Jonathan Schwartz gives a keynote address at Oracle Open World conference in San Francisco.

Schwartz managed a classic of the genre when he quit his job in a philosophical tweeted haiku in 2010: "Financial crisis/Stalled too many customers/CEO no more." (AP Photo/Paul Sakuma, File)
