Jono is in support of Fedora 17's Beefy Miracle so much that he decided to dress up as the friendly competitor's mascot for the Halloween party during the Ubuntu Developer Summit in Orlando, Florida.
Jono dressed up as a hot dog, which matches that of the "Beefy Miracle" mascot as found on BeefyMiracle.org, which was the web-site to promote the Fedora Linux codename.
Fedora 17 is due out as Red Hat's first community release in 2012 and will feature GNOME Shell on LLVMpipe, an updated graphics stack, potentially Btrfs by default, and other changes. This Beefy Miracle release will be in friendly competition to Ubuntu's 12.04 release codenamed Precise Pangolin, which will come out in April. There's a lot coming up for Ubuntu 12.04 too, as talked about in the numerous UDS Phoronix postings (my summary article will be out this weekend).
Yes, I did talk this over with Jono, and he is well aware of his costume matching that of the Fedora 17 "Beefy Miracle" theme. (Surprisingly, few others at this Ubuntu Developer Summit party realized the Beefy Miracle reference to Jono Bacon dressing as an American hot dog.)
Sadly, the lederhosen are not visible to complete this photo.
Perhaps this further brings to light Jono Bacon is really Jef Spaleta? ;)
