So you’re a roboticist, looking at Ubuntu Core and Snappy, trying to decide if they’re a good fit for your project. You come across some ROS documentation and realize that the ROS support is first-class, but you’re not using ROS. No, you’re using the Mission Oriented Operating Suite (MOOS). Why is there no documentation on using MOOS? Because it’s too easy to need a document, that’s why (update: this remains true, but we wrote a quick one anyway)....

The officially-supported Ubuntu Phones run pretty old kernels. The Nexus 4 and BQ phones all run v3.4, and the Meizu MX4 runs v3.10. Device kernels typically lag a bit behind since so much effort goes into making them compatible with the hardware, but this posed a bit of a complication since the Click confinement model utilizes features of AppArmor v3, which isn’t even released yet. However, we like to push the envelope here at Canonical, so we backported it into our phone kernels anyway....
