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.
