Calculating PI in .NET

December 30, 2011

I always loved mathematics. Although I’m certainly not a mathematician by profession, I’m always intrigued and inspired by math’s pureness and cleverness. One of the simplest and fascinating aspects of math is the number PI. Described simply as the ratio of a circle’s circumference to its diameter, it’s a constant with infinite digits after the decimal point and most importantly, non repeating (at least as far as I know). There are many ways to calculate PI, as evident within the PI Wikipedia link. I wanted to see how I can get a large number of digits of...

Getting Device Information in Windows Phone 7

December 19, 2011

Windows Phone 7 mandates a set of minimum requirements from devices it runs on, such as camera resolution, hardware graphics support, the existence of sensors such as microphone, GPS, touch, etc. However, sometimes it’s useful to know the exact specifications of a particular device the application is running on, so the application can optimize. As a simple example, running on the emulator or a real device can make a huge difference – maybe the application has a way of doing things differently when running on the emulator for testing purposes. The device information is exposed primarily through the...

My Sessions at the MobiWeb Conference

December 16, 2011

The MobiWeb Conference is scheduled for the 15-17 of January in the Daniel Hotel in Hertzliya (Israel).

The fist, “Building Windows Phone 7 Apps with Silverlight” (on the 16th) will cover the development for the (relatively new) Windows Phone platform using Silverlight (and maybe some XNA if we have time). Anyone looking into developing applications for this exciting and capable platform should get a good head start by...

WPF Tip: Binding to the Selected Item in a Master-Details View

December 6, 2011

Master-details is a common way to display data. A master view provides minimal data for a collection of objects (e.g. book names), and when selecting one such item, a details view provides more information for the selected item (e.g. a book’s name, author, publication date, etc.). In WPF, data binding (in XAML) is typically used to achieve the connection between an object and its details without using any code. Let’s see how we can achieve this. Let’s say we want to show a list of book names, and when a book is selected, we want to show...
