Oracle vs. Google... and the web?
Unless you've been living under a rock, by now you've heard about the case that is certain to keep the armchair lawyers busy for years to come: Oracle vs. Google. It's already been dissected elsewhere, but in a nutshell: Sun owned their GPL-licensed Java virtual machine, and various patents on it; Google wrote their own JVM for the Android platform, Dalvik; Oracle bought Sun; Oracle uses those patents to sue Google over their JVM; Hilarity ensues.
So what? How does that affect us, as PHP and Drupal developers? Well it doesn't... except indirectly via another product that Oracle bought as part of Sun: MySQL.
