Well, that didn't take long. Barry Klawans, former CTO at JasperSoft,citing the need to unwind and spend time with his family.
Apparently, six weeks of that was all his family could stand, as he has joined Hyperic (on a part-time basis) to help with its JasperSoft integration. His kids are crying...
Welcome back, Barry. If your kids are like mine, you'll never leave us for long. :-)
