Linux kernel devs adopt Bill and Ted's excellent code of conduct

The Linux kernel development community and its leader Linus Torvalds are both famously feisty: strong words are often exchanged on the Linux Kernel Mailing List, while Linux Lord Linus Torvalds is seldom shy of speaking his mind. Of late, however, Torvalds has copped some criticism for being a little too strident, perhaps …
