Michael Schwern, prominent Perl developer and keynote speaker at the National Center for Women & Information Technology's 2013 summit, was arrested in Portland, Oregon on Sept 19, 2013 on two counts of misdemeanor domestic violence charges against his then-spouse Nóirín Plunkett -- specifically, harassment and strangulation. The arrest coincides with the day the couple filed for divorce (also Sept 19, 2013). Schwern was previously known in the Open Source community for giving public talks about diversity.
