I just wish they didn't kill RoboVM. I get the warm and fuzzies when something big is open sourced just like everyone else. Then I snap back to reality and remember that it's ultimately the same organisation that close-sourced RoboVM then killed it, screwing over a lot of people depending on it.
Seriously, RoboVM could have been huge. An ingenious way to introduce app development to your existing hordes of Java devs. Great tech, killed because of business decisions...
