So the JavaScript developers feel right at home...

	let NaN = NaNClass()

	@infix func == (n1: NaNClass, n2: NaNClass) -> Bool {

If you have uncrustify on your machine, this script will format all .h and .m files that it detects as Objective-C, like gofmt does.

	#!/usr/bin/env ruby

	require 'tempfile'

	def main
	if needs_uncrustify?
	puts "Could not find `uncrustify` on the path. Try `brew install uncrustify`."
	exit 1
	end

	sudo defaults write /Library/Preferences/com.apple.windowserver DisplayResolutionEnabled -bool YES;
	sudo defaults delete /Library/Preferences/com.apple.windowserver DisplayResolutionDisabled;

	// by the way, you need to logout and log back in for this to take effect. Or at least that's what
	// Quartz Debug says. Who knows, maybe it's lying?

	// P.S. Go to [Apple menu --> System Preferences --> Displays --> Display --> Scaled] after logging
	// back in, and you'll see a bunch of "HiDPI" resolutions in the list to choose from.

Here's how I'm generating a set of 1,000 random strings with between 4 and 14 random lowercase characters. Is there a better way?

	@implementation SomeGenerater

	- (NSArray *)generateAThousandRandomStrings
	{
	NSMutableArray *strings = [[NSMutableArray alloc] initWithCapacity:1000];

	for (int count = 0; count < 1000; count++) {
	int length = arc4random_uniform(10) + 4;
	unichar buf[length];
