Don't look now, but one of the staples of the open source world just marked a big birthday. Canonical has released Ubuntu 14.10, officially making this friendlier Linux distribution 10 years old. The company is clearly happy with a low-key celebration; 14.10's biggest addition is a developer tool center that makes it easier to write Android apps, while you'll also find support for zero-setup printers and 64-bit ARM chips. Not exactly riveting stuff, is it? Still, the release shows how far Ubuntu has come -- while there have been some rough patches in the last decade, the Canonical team can now focus most of its energy on refining a successful formula.
