Simple implementation of a thread safe mutable dictionary. In most cases, you want NSCache instead, but it can be useful in situations where you want to manually control what is evicted from the cache in low memory situations.**Warning:** I only use this for setting/getting keys. Enumeration is not thread safe here and will still throw exception…

This is a guard that tracks down UIKit access on threads other than main. This snippet is taken from the commercial iOS PDF framework http://pspdfkit.com, but relicensed under MIT. Works because a lot of calls internally call setNeedsDisplay or setNeedsLayout. Won't catch everything, but it's very lightweight and usually does the job.You might n…

Paul Heckel's Diff Algorithm

[Isolating Differences Between Files][paper]

Advantage over Other Algorithms

The diff output is more specific:

[I]f a whole block of text is moved, then all of it, rather than just the beginning and end, is detected as changed.

>The algorithm described here avoids these difficulties. It detects differences that correspond very closely to our intuitive notion of difference.
