JSView is a nice firefox addon that let's you see the source of external js files for example, easy.
From the description of the addon:

Here is a nice way to get the value of a $_GET in php (i think it will also work with $_POST)

function get($value)

{
   $valoare = isset($_REQUEST[$value]) ? addslashes(strip_tags($_REQUEST[$value])) : '';
   return $valoare;
}

In case you want to make sure javascript wants to add two values instead of concaternating them when you use "+" you can make them act as an int for example with parseInt:

a+1 might concaternate
parseInt(a) + parseInt(1) will add

It was kind of hard to make a bi dimensional array in javascript; i struggled a bit when i needed to do so; so tgis is what worked for me eventually:

I found a way to debug javascript, in case something more powerfull is needed:

The how to is described here: http://www.jonathanboutelle.com/mt/archives/2006/01/howto_debug_jav.html

This is how you call a javascript function from actionscript (2 I think):
on (press){
getURL("JavaScript:function(argument)");
}

Mysql has something called full text search, that returns results by relevance. Kind of like google does. The downside is that it can only be used on MyISAM tables, which unlike InnoDB tables, lock the entire table when it's being written to, instead of locking only a row.
For a table that is very ofter being written and read from that could be hard to take.

I liked this query a lot so i wanted to remember it.It's simple but pretty cool:select column, count(column) as numfrom tablegroup by column having num > 1;

I saw this here i think.
It's a simple way to block certain ip's you might suspect want to give you invalid clicks to get you banned in adsense.
Of course first you have to have a list of ip's you suspect to be ill intentioned, and that isn't very likely to happen in the real world, but if you do, here is what you could do.
