Wow. A rolling-release Linux user. You guys are a rarity.

Mostly Ubuntu 14.04 LTS (upgrading to 16.04 LTS before second point release), there's Windows 7 Ultimate but use it rarely these days owing to lack of time to play games. FreeBSD 10.3 and Debian 8 on VPSes. At work, it is Windows 7 Enterprise and Ubuntu 14.04 LTS
16.04 is nice, since you get the latest in terms of repositories. Though I did find that it changed some of the networking operations and made them blocking, which made me rewrite some of my countdown-and-kill functions.
