The SLOLUG (San Luis Obispo Linux Users Group) is a community of people interested in Linux, computer technology and security.

We meet once a month at the KCBX Training Center in San Luis Obispo to share our experiences about Linux, demonstrate applications and features of the Linux operating system. Other discussions include computer hardware as it applies to Linux and interfacing with the Windows or MAC operating system. Talks and discussions vary widely on a variety of computer technology topics.

Even if you're a macOS or Windows user, they're many reasons to use Linux.
