Linpro held the annual "Linuxdagen" ("Linuxday") 7. May 2007. It was the usual mix of interesting and not so interesting presentations. There was a lot more people attending this year than last year - which was great. My presentation about SELinux dealt with how SELinux enforces "mandatory access control" (MAC) instead of the traditional "discretional access control" (DAC) on Linux. Handout can be found here (norwegian).
