The future of realtime Linux in doubt

In a message about the release of the 3.14.10-rt7 realtime Linux kernel, Thomas Gleixner reiterated that the funding problems that have plagued realtime Linux (which he raised, again, at last year's Real Time Linux Workshop) have only gotten worse.

Garrett: Self-signing custom Android ROMs

Matthew Garrett explains
how to get an Android device
to refuse to boot an operating system that
has not been signed by the device's owner. "It's annoying and
involves a bunch of manual processes and you'll need to re-sign every

way that you retain the same level of security you had when you were using
the Google keys without losing the freedom to run whatever you
