10 tile rule

phrase- simply means that if you're ever forced to go somewhere in public with your parents (the local mall for example), and you don't want to be seen in this humiliating situation, you walk 10 tiles ahead of your parents, nobody will ever notice that you're with them. The whole thing goes out the window if they scream your name out across the mall, but the entire situation can be avoided completely if you just bring your cell phone and they allow you to leave their watchful eyes.
John: I have to go to the mall with my parents, and for some reason they said I can't leave their sight.
Joe: No sweat man. All you have to do is use the 10 tile rule.

20-second rule

Any computer application must respond to input within twenty-seconds or the person using it will think that the software is broken and begin pressing the "Any Key" to elicit a response.

Internet latency is not an excuse for failure to respond; c'mon, even satellite links have less than 20 second latency.
The iPhone has a 20-second rule start-up timer; if an application takes longer than 20 seconds to start up, it is killed by the iPhone OS. Also, the iPhone OS will kill any application that is unresponsive for longer than 20 seconds.

Usually seen on poorly built web pages that rely on over-taxed advertising servers.

Also violated by Windows OS during the boot process where it waits a whole freaking minute for network connections that are never connected to time out.

ten minute rule

The amount of time a DVD supplied by a through-the-post rental service has to prove itself watchable. A way of dealing with the inevitable question; "Who the hell picked that!?" when some discs arrive. A damage limitation excercise. Life is too short for bad movies.
Shyamalan's The Happening dropped through the door in the morning so we thought what the hell. We used the ten minute rule. It didn't make it.
