Kernel Recipes 2016

BayLibre was proud to be a sponsor of this this years Kernel Recipes conference in Paris.  Kernel Recipes is a small, technical conference focused on various topics related to the Linux Kernel.

kr-crowdI was a speaker again this year, and  gave a talk about the kernelci.org project.  The talk was a brief overview of the project, its history and ways to contribute.   Slides available here and video recordings are also available.

One of the fun parts of Kernel Recipes was all the speakers and some lucky audience members got caricatures of them drawn by artist Frank Tizzoni.  Here is one of me and one of the crowd, with a bunch more available on Kernel Recipes Twitter feed.
