SCALE is a renowned annual Linux Expo held in southern California. It’s also the biggest Linux and FOSS (Free and Open Source Software) showcase event run by various members of the Linux community in North America. SCALE 15x is the fifteenth installation of the conference. SCALE 15X will be held between March 2-5 at the Pasadena Convention Center, and it would appear that Canonical is planning to organize a new UbuCon Summit event, which will gather together the entire Ubuntu community and all the big names behind one of the world’s most popular free operating systems.
