LPC 2010

As Lennart just posted the Call for Papers for the 2010 Linux Plumbers Conference (LPC)closes this Monday (the 19th of July). The goal of LPC is to get people working on the various projects that make up the key Linux infrastructure where the kernel and application layers meet together so that everyone understands everyone else's needs and all the components of the system can be made to work together as well as possible. This is the third year the conference has been run, with the previous two years having been very productive, and we hope that the event this year will be equally successful.

This year I will be joining Lennart Poettering in helping to organize the audio track, with my particular focus being on the needs of embedded systems.
