Bizarre Droid Auto-Focus Bug Revealed

itwbennett writes "Pity the poor engineer who had to find this one. One of the more interesting of the handful of bugs that have appeared since the launch of Verizon's Droid smartphone has to do with the on-board camera's auto-focus. Apparently it just didn't work. And then suddenly it did. Naturally, this off-again, on-again made the theories fly. But the real reason for the bug was revealed in a comment on an Engadget post by someone claiming to be Google engineer Dan Morrill: 'There's a rounding-error bug in the camera driver's autofocus routine (which uses a timestamp) that causes autofocus to behave poorly on a 24.5-day cycle,' said Morrill. 'That is, it'll work for 24.5 days, then have poor performance for 24.5 days, then work again. The 17th is the start of a new 'works correctly' cycle, so the devices will be fine for a while. A permanent fix is in the works.'"

You don't need a period after a quoted sentence that is properly terminated. Consecutive dots, are consecutive dots after all.

For a programmer unbalanced sentence termination characters are just bad.

The only problem with the Slashdot mod system is that you can't hunt the moron down who either can't read, or doesn't pay attention, and beat them to death the way Darwin intended ;-)
