Old talk from 2001 -- but priceless review of SunOS / Solaris and open sourcing ‪#‎opensolaris‬ / ‪#‎illumos‬ by Bryan M. Cantrill, now at Joyent. Focus on effort to really open source stuff at 20:00, and license clarifications of why they went with a CDDL license around 23:10, he notes they didn't purposely try to make CDDL GPL incompatible, listen for details of why Ben states they needed a different license there. Then a very beautiful rant on Oracle starts circa 34:00... Tons of lessons to be learned from a community going ‪#‎opensource‬ here.
