Kernel Changelog Tidbits for Glass

I've always enjoyed teardowns of of the software in new products. As you can expect, I loved the detailed writeup of the secrets found in Google Glass's kernel source at http://thecodeartist.blogspot.ca/2013/05/sensors-on-google-glass.html . However, when that article is written, the source code of the kernel was just served without the changelog (provided by their version control system, Git). Since then, Google had released the kernel with full change information on AOSP.

If you want to dig around the logs yourself: https://android.googlesource.com/kernel/omap/+log/glass-omap-xrr88/ with highlights at https://android.googlesource.com/kernel/omap/+log/glass-omap-xrr88/arch/arm/mach-omap2/board-notle.c and https://android.googlesource.com/kernel/omap/+log/glass-omap-xrr88/arch/arm/mach-omap2/notle-usb-mux.c . More eyes will probably uncover more secrets.

Open Conference Expectations

This document lays out some baseline expectations between conference speakers and conference presenters. The general goal is to maximize the value the conference provides to its attendees and community and to let speakers know what they might reasonably expect from a conference.

We believe that all speakers should reasonably expect these things, not just speakers who are known to draw large crowds, because no one is a rockstar but more people should have the chance to be one. We believe that conferences are better -- and, dare we say, more diverse -- when the people speaking are not just the people who can afford to get themselves there, either because their company paid or they foot the bill themselves. Basically, this isn't a rock show rider, it's some ideas that should help get the voices of lesser known folks heard.

These expectations should serve as a starting point for discussion between speaker and organizer. They are not a list of demands; they are a list of rea
