Why not tune into XDC 2016 to learn how the Linux graphics stack is built in a collaborative fashion - it's like a lab meeting, just longer and usually with actual results :) [i'm extrapolating from almost any lab meeting i had to experience in my old lab, base lines may vary]
Live stream available starting Wednesday morning:
In other news, i'll be mostly offline at least for the week when i'm at the conference.
