Mark your calendar, CodeStock 2010 will be June 25-26, 2010.  This year we are moving to a bigger and better location, the University of Tennessee Convention Center in downtown Knoxville, TN.   There will also be some events held at the historic Bijou Theater, also located in downtown Knoxville.

If you are in the technology field, or within the listening range of modern media, you've heard of the Apple iPad.  The fact that it runs an updated version of the Apple iPhone OS is a big plus if you are looking to do development on the platform.  I've already received a bunch of emails about this, so I wanted to share what you can do to do develop on the platform right now.

If you didn't know it, the iPhone has two twenty second rules that developers need to pay attention to:

There are times when the user needs to be presented with some information or question. MonoTouch has a UIAlertView object. The UIAlertView is instantiated with a set of parameters. On the object instance, the .Show() method is called. For .NET developers, this is similar in concept to the .NET MessageBox. For JavaScript developers, this is similar to the window.alert() and window.confirm() methods. 

The NSUrl class is what allows an application to open other applications within the iPhone OS while passing parameters. The calling sequence is fairly simple. There are two steps to making this call:
1. When the NSUrl class is instantiated, a string representing the URL scheme is called. Note that different applications will have different schemes and use different protocols.
2. The static method UIApplication.SharedApplication.OpenUrl(ns) is called, where ns is the NSUrl class. When the static method is called, if it is not possible to open a URL, a false is returned. If it is possible to open the URL that is passed, the URL is opened and a true is returned.
