Open-source (mostly) on the plane

On a recent Delta flight (I believe we were on a B737-800), the seat-back entertainment system needed to be rebooted, so everybody on the plane got to watch the startup messages scroll by. It was a Linux system booting with Redboot, running on a single-processor system (to judge from the single Tux graphic on boot). I was entertained by the warning that the kernel was being tainted by non-GPL code.

CSPI does something useful?

Airborne, the anti cold preparation, has not admitted that it can’t actually prevent or treat colds, but is now refunding money! That sure took a while! So one only has to live through 9 years of coworkers enthusing about a cold nostrum with no possible mechanism to do what it says it does. Unfortunately, I think homeopathy is still protected from legal action for ineffectiveness by grandfather clause.
