Auto Layout is a contraint-based, descriptive layout system. Describe the layout with constraints, and frames are calculated automatically.

Whay Auto Layout?

Relational: Codifying the relative way we describe interfaces
Dynamism: Improved responsiveness to changges
- Metrics: iOS 6 to iOS 7, screen sizes, and rotation
  - The user can actually change the size of the font on the fly.
  - Using Auto Layout and using relationships to describe things like spacings, alignments, equal size, these are the things that are going to translate regardless of what the size of the container is, so the size of the control, the size of your contents. *Content: Localization

Installing Cassandra on Mac OS X

Homebrew is a great little package manager for OS X. If you haven't already, installing it is pretty easy:

ruby -e "$(curl -fsSL https://raw.github.com/Homebrew/homebrew/go/install)"

This gist shows how to create a GIF screencast using only free OS X tools: QuickTime, ffmpeg, and gifsicle.

To capture the video (filesize: 19MB), using the free "QuickTime Player" application:

	func resize(image: NSImage, w: Int, h: Int) -> NSImage {
	var destSize = NSMakeSize(CGFloat(w), CGFloat(h))
	var newImage = NSImage(size: destSize)
	newImage.lockFocus()
	image.drawInRect(NSMakeRect(0, 0, destSize.width, destSize.height), fromRect: NSMakeRect(0, 0, image.size.width, image.size.height), operation: NSCompositingOperation.CompositeSourceOver, fraction: CGFloat(1))
	newImage.unlockFocus()
	newImage.size = destSize
	return NSImage(data: newImage.TIFFRepresentation!)!
	}

	import Foundation

	/// Given pointer to first element of a C array, invoke a function for each element
	func enumerateCArray<T>(array: UnsafePointer<T>, count: UInt32, f: (UInt32, T) -> ()) {
	var ptr = array
	for i in 0..<count {
	f(i, ptr.memory)
	ptr = ptr.successor()
	}
	}

	@interface MySingleton : NSObject

	// ...

	+ (instancetype) sharedInstance;

	+ (instancetype) alloc __attribute__((unavailable("alloc not available, call sharedInstance instead")));
	- (instancetype) init __attribute__((unavailable("init not available, call sharedInstance instead")));
	+ (instancetype) new __attribute__((unavailable("new not available, call sharedInstance instead")));
