1. NSObservedObjectKey, which is the object that the binding is bound to;
2. NSObservedKeyPathKey, which is the key path that is bound — in Interface Builder terms, this is the controller key path combined with the model key path, with a dot in between them; and
3. NSOptionsKey, which is a dictionary of additional binding options unique to the binding. These are all of those additional checkboxes and pop-ups in the Interface Builder bindings inspector for setting things like a value transformer.

I took a step back and tried to figure out what the hell was going on. After a few minutes, I realized that Xcode was actually doing a really, really, really good thing. The vast majority of problems that arise from a poor separation of concerns between the GUI and the underlying code, model, and controller (if you even have such constructs in your app!) stem from the fact that you can double-click a button and immediately start writing code without thinking about the consequences of such a thing.

The NIB (stands for NeXTStep Interface Builder) file is a loosely coupled, standalone, user interface definition. It wouldn't make sense to double-click a button and immediately be taken to a code-behind. Instead, you have to create a controller class, and then ctrl-drag from the button to the controller and then pick the outlet you're going to use (something like click: or calculate:). To me, as a huge fan of the MVC pattern, this makes perfect sense. And it seems so elegant in its simplicity, and so incredibly cool in the fact that it is truly enforcing good design simply by the way the IDE works.

The developer tools in Mac OS X Leopard are crafted for one mission: to enable you to create amazing applications. Offering a streamlined workflow, Xcode 3.0 helps you develop your applications faster than ever. The all-new Interface Builder lets you build awesome user interfaces that take full advantage of Leopard's capabilities. The new language features in Objective-C 2.0 speed up your development cycle. The innovative new Xray brings the ability to visualize your application at runtime in a way that's never before been possible. And, the brand-new Dashcode makes it a snap to create elegant and powerful Dashboard widgets.

So by Enterprise, Architect, and Enterprise Architect standards, this gent must be the top of the pop. Thus, allow me to make this perfectly clear: I would be as happy as a clam never to write a single line of software that guys like James McGovern found worthy of The Enterprise.

If Ruby, Rails, and the rest of the dynamic gang we're lumped together to represent, is not now, nor ever, McGovern Enterprise Ready™, I say hallelujah! Heck, I'll repeat that in slow motion just to underscore my excitement: HAL-LE-LU-JAH!

With that out of the way, we're faced with a more serious problem. How do we fork the word enterprise? The capitalized version has obviously been hijacked by McGovern and his like-minded to mean something that is synonymous with hurt and pain and torment.

13. Lets say there is a sixteen week project and the productivity stuff was true and Ruby could save me an entire three weeks which would be significant. Since Ruby is a new vendor and not represented by existing vendors I already do business with, do you think that I will spend more than three weeks in just negotiating the contract?
