Simple main thread usage detector that I'm using in PSPDFKit to find performance problems early on.

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…

Works around the issue where UITextView doesn't scroll to the new line until there's a character in there. Super horrible workaround.
- (BOOL)textView:(UITextView *)textView shouldChangeTextInRange:(NSRange)range replacementText:(NSString *)text {
// Horrible HACK for bug in UITextView where it won't scroll to the new line after pressing enter in the text view.
// I feel dirty for having to write this. Buggy at least within iOS 7.0 - 7.1b1.
if (PSPDFIsUIKitFlatMode() && [text isEqualToString:@"\n"] && range.location == textView.text.length) {
dispatch_time_t popTime = dispatch_time(DISPATCH_TIME_NOW, (int64_t)(0.1 * NSEC_PER_SEC));

CGFloat fontSize = textView.font.pointSize;

How to connect PS3 controller to a Mac or PC

This is how you connect PS3 controller to Mac OSX, PC, etc. when previously connected to a PS3. You will need a Mini USB cable. Overcome your laziness, get up of your chair, and go get one!

A big misconception is that keep holding PS button will reset the controller's pairing. It DOES NOT! From my testings, the controller keeps paring with the last machine it was CONNECTED VIA A USB CABLE.

Here are the steps:
