Linux Users' Group of Davis (commonly known as LUGOD) is a users' group of students and faculty from the University of California, Davis, Information technology professionals from the Sacramento region, and hobbyists interested in Linux and free and open-source software. It holds regular meetings in Davis, California, and holds installfests on a regular basis. Its members participate with each other online in numerous mailing lists and via Internet Relay Chat.
The group was founded in early 1999 by Peter J. Salzman, Bill Kendrick, and about a dozen others, following a USENET posting in which Peter asked whether such a group existed in the Davis area. (Salzman and Kendrick held posts as president and vice president for most of the first five years of the group's existence.)
When possible, LUGOD participates in many activities, including hands-on demos, exhibit booths at events such as LinuxWorld Expo, classes, fundraisers, and organizing the annual Linux picnic in Sunnyvale, California, together with other SVLUG and other groups.
The LUG's website maintains a collection of news articles meant to help convince users to switch from Microsoft products.  Eric S. Raymond linked to this collection in his famous response to Microsoft's eighth Halloween document. 
Despite its distance from the Silicon Valley, numerous notable speakers have presented at LUGOD, including:
