This video demonstrates the new user interface and the app tiles in Windows 8. It also shows a few basics of how to make life easier using Windows 8 and power options. Windows installed by the default options will choose the Balanced power plan which will not give you the best output from your processor. Selecting a High performance powerplan in the background will also allow your processor to use more power and be more efficient.

Next were going to hook up the UI for our main application page through the DefaultViewModel collection.
A page of type Items has a default View Model defined, and it is possible to hook up to a data source with only a few lines of code.
Once done, the page will render the items in the default template format. Of course,customization will likely take place from the default settings.
In this video, I will show you how to bind our data feeds to the DefaultViewModel[Items] element of our ItemsPage.

When working with files in Objective-C, we can specify the paths to them as follows:
NSString *path = @/Users/pavel/file.txt;
However, the recommended way (by Apple engineers) to specify that is by using URL-s (Uniform Resource Locator).
The iOS SDK class that provides us urls manipulation is named NSURL, and it has a lot of class convenience methods that make developers lives easier.
To create a NSURL object, we use the syntax:
NSURL *url = [NSURL URLWithString:@file:///Users/pavel/file.txt];
Note that the way we specify the string is different from in path cases.
It should always have the file schema in front of it, than a colon, and 3 slashes.
If we want to create a NSURL object, providing a string as in path cases, we can use a NSURL method which allows us to do that:
NSURL *newUrl = [NSURL fileURLWithPath:@/Users/pavel/Public/file.txt];
To move files from one location to another using urls instead of paths, we should use:
[[NSFileManager defaultManager] moveItemAtURL:url toURL:newUrl error:nil]; Working with paths and urls in Objective-C](https://i.ytimg.com/vi/xix_7Nqa7qM/mqdefault.jpg)
