> console.log(/foo/);
/foo/

SQL Update with row_number()
...rver seems to update the row even if the value already exists and it takes time to do so, so adding the where clause makes it just skip over rows where the value hasn't changed. I have to say I was astonished as to how fast it could run my query.

Jquery mouseenter() vs mouseover()
...arget element contains child elements:
http://jsfiddle.net/ZCWvJ/7/
Each time your mouse enters or leaves a child element, mouseover is triggered, but not mouseenter.
