Southern California Linux Expo (SCALE) is a venerable and-well regarded volunteer-run, regional Linux conference that draws over 2000 attendees and an amazing array of speakers and open source projects displaying their goodies in the exposition area. The tutorial and speech schedule is crazy-dense, with as many as 10 tracks going at once. Conference Chair Ilan Rabinovitch admits that there is no way you can take in all of SCALE. On the other hand, you are certain to find something new and interesting to learn if you have any interest at all in Open Source. And yes, we mean Open Source, not just Linux. This show has grown far beyond its humble roots as a get-together for a few local students interested in Linux. One last thing: When you register, if you use the promo code SLASH, the $70 pass for all three days is magically reduced to $35. And there are many other ways to get that discount or another one just like it, including affiliation with virtually any Southern California Open Source group or almost any Open Source project. SCALE is 100% non-profit, and wants to "spread the word," not make money.
