Thanks to our frequent liveblogging and writing while solely on laptop power, we’re always cognizant of how much CPU load we’re putting on our machines. One thing we’ve noticed is that Flash—the thing that makes YouTube videos move and advertisements blink—puts an abnormally large load on your processor, which makes for a dramatically decreased battery life. If you’re using Firefox, use Flashblock to disable Flash except for certain sites, and if you’re using Safari, use Safari Stand. IE sufferers can use Toggle Flash.
