Keith Packard Talks About Sustaining X11's Development
With Keith Packard having been working on X since the late 80's and is serving as the current X.Org Server release manager, he certainly has a vested interest in keeping X going, particularly after the round of modernization work over the past few years of kernel mode-setting, DRI3, moving towards hardware-independent drivers like xf86-input-libinput and xf86-video-modesetting, etc. He remains focused on making the X.Org Server better.
While Keith is no longer at Intel but back at HP to work on Linux++ / The Machine, he was at XDC2015 talking about sustaining X development.
Among the lessons learned that he mentioned about X.Org development were GPL licenses are better than BSD, network-based collaboration works, build the simplest possible solution, and make it extensible.
