- Linux kernel appears to have a significant power management regression
Slashdot points to some interesting empirical data derived from manual testing of the current kernel, to be included in the looming Ubuntu update, and reaching back to compare against a handful of historical versions.

Hopefully now that this has been spotted it will be rapidly addressed.

Jeff Atwood shares of his more clueful first hand lessons in application scaling at his Coding Horror blog.
