So Steve Jobs has finally announced the availability of the iPhone SDK. It will be available sometime in February of 2008. First, before I go on, I want to counter a lot of the press and blog comments stating that the release of the SDK is a reversal or some kind of about face. If anybody had done their homework, they would know that Steve Jobs himself stated that he wanted to create an environment that supported native 3rd party app development, but that they didn't have it "right" just yet, and that he wanted people to be patient. Obviously, he didn't remember that patience is one quality few techies (including myself) possess. So where are we now? Does the announcement of the native, Cocoa-based SDK mean that web development for the iPhone and iPod touch are dead? Absolutely not. There are still a truckload of advantages to doing iPhone web development. To me, th... (more)

ADO.NET Data Services Projections Makes Sliced Bread Jealous

The other day I ran into a blog entry from the Astoria team discussing the projections feature of the 1.5 CTP2 version of the product. If you're not familiar with ADO.NET Data Services (formerly codenamed Astoria), it's basically a layer that you can put on top of an Entity Data Model and it will expose that model as a RESTful service. The URL format for this RESTful service is quite flexible, allowing you to select individual rows, perform filters, sorts, and many other things. One of the new things that you can now do server-side via the new CTP2 URL syntax is projections. Pro... (more)

Cocoa - Exploring the Delegate Design Pattern

Kevin Hoffman's Blog When I first started learning Cocoa I ran across a design pattern that I had seen implemented a few times before but I had yet to see it labelled with a name. This pattern is called the Delegate design pattern. Coming from C#, I found this initially confusing because in C# the concept of a delegate is slightly different than the concept of a delegate in the Cocoa world. In C#, a delegate is essentially a function pointer, and when someone in Cocoa refers to a delegate, they are referring to an entire instance of a class to which work is delegated. To see how...

Astoria Client Library Available for Silverlight 1.1 Alpha

Kevin Hoffman's Blog Before I begin, rush out and download this thing right now. Here's the link. As you probably know, Silverlight is Microsoft's new RIA technology platform. It purports to provide a single development platform that will allow you to deploy WPF-like rich applications to multiple operating systems through multiple browsers. For example, you can write your XAML and C# and deploy that to a server which can then be consumed by people using IE on Windows Vista or people using Safari on OS X (Tiger only right now, Leopard support is forthcoming). On the other hand, As... (more)

Why Is iPhone Better? Here's My Story...

If you take a look at the success of the Nintendo Wii, you'll see an innovative device with an incredibly compelling user interaction design (the Wiimote, nunchuck, steering wheels, fitness pads, etc). The device itself has what the industry might actually refer to as "last gen" hardware. The video card is weak relative to the PS3 and Xbox 360, it doesn't come with built-in LAN (though you can buy a LAN/USB adapter for it), it has less memory and less processor power than the PS3 and Xbox 360. Yet, despite these so-called deficiencies, everybody seems to love their Wii, and it's ... (more)
