ReactOS Portable Systems Group
A bunch of people very knowledgeable in ARM programming, also known as the ARM ninjas (AKA Code Ninjas). And no, Alex isn't one of them. We're (almost) positive of that.
They are known of sharp, witty commit messages, often depicting various ReactOS code failures in a quite sarcastic way. Note that even they managed to get ROS a bunch of regressions, luckily fixed quite fast.
