How to see if an NSString starts with a certain other string?

Here's a post I wrote about it: The real reason select queries are bad index coverage
It's also less fragile to change, since any code that consumes the data will be getting the same data structure regardless of changes you make to the table sche...
How do negative margins in CSS work and why is (margin-top:-5 != margin-bottom:5)?
...moving the element 8px up does not cause any further disturbance to the layout; with static in-flow content that's not always the case.
