Linucon was a combination Linux expo/science fiction convention in Austin, Texas. Conceived as a "sister convention" to Penguicon, Linucon was co-founded by Rob Landley and Stu Green.
Two Linucons were held. The first Linucon was held October 8–10, 2004, at the Red Lion Inn located at 6121 North I-35 in Austin. Linucon 2.0 was held September 30 – October 2, 2005, at the Ambassador Hotel located at the intersection of I-35 and Highway 183.
The science fiction side had three main tracks: an anime track, a literary track, and a gaming track. These tracks included cosplay (and a Masquerade), filk, a dealer's room, panels, author readings and signings, Birds of a Feather sessions, and an art show. The convention suite featured caffeinated Jello and ice cream made with liquid nitrogen. There was also a live action role-playing game. The video room played around the clock and both gaming rooms (computer and paper) were open 24 hours.
