Tired of nine zillion revisions of your posts created on your WordPress site?
Open up wp-config.php with a nice editor like Emacs or Pico/Nano or VI and add:
define('WP_POST_REVISIONS', false );
to disable post revisions completely.
Or, if you just want to limit the number of revisions WordPress keeps:
define('WP_POST_REVISIONS', 3);
Of course, this is just a simple Google query away from you:

Or, as it happens:

Using jQueryMobile for a fairly lightweight “mobile site”, I wonder what all you experts say about selection sets. A (long) list of countries for example. To prevent excessive delays, I now split country selection in two screens. The first one shows A-Ö (A-Z for you English-speaking people), if I tap on B, the next screen shows a list of countries starting with B. Hitting the back button brings me back to A-Ö (A-Z), selecting a country takes me to.
It feels right, and it doesn’t transfer massive amounts of data that a) isn’t used half of the time, and b) doesn’t take time to render on slower mobile devices.
