Click to view"Just heard that Monty gave his resignation to Sun today," a tipster we trust writes about Michael Widenius, the Finnish-born main author of open-source database software MySQL. Sun Microsystems had aqcuired Monty's company, also called MySQL, for a cool billion in January. So who's running the show now? Best guess is Brian Aker, another prominent MySQL developer. Aker released a lightweight, Web 2.0-oriented version of MySQL called Drizzle in late July, but he's still at Sun.
