SCaLE 15x (The Southern California Linux Expo) put on yet another wonderful full-day MCLE on Free and Open Source Law. I spoke on recent US Copyright cases and their applicability to the Free and Open Source Software world.
Slides on APIs and CLIs in US copyright law available here in case others may find them useful. (As usual, feel free to use, quote, distribute, etc. so long as you leave my copyright notices in place for substantially similar works and note my presentation as the source for any material you may use in derivative works you may create.)
