New Features in Wolfram|Alpha: Year-End Update
The guys at Wolfram|Alpha have been working hard to bring you the best computational knowledge engine available out there, and for free. Even though Wolfram|Alpha is already a most powerful tool, developers have been working to improve it even further and have brought a full pack of entirely new and improved features before the year-end.
This new features cover all available categories, from mathematics and computation to science and culture. Comparing house prices in your area, reading available crime statistics from FBI, exploring a vast information about music, and check on military information, are just a few of the new planned features before the year-end.
You can read all about the new features at Wolfram|Alpha official blog and don’t forget to check the engine itself at WolframAlpha.com. A must see, if you haven’t already.
Take care.

Throughout the net there are plenty of different alternatives on how to change Windows 7 logon background.
Well, Julien Manici, using WPF, created a very simple application that allows you to change Windows 7 logon background with only a few mouse clicks.
Windows 7 Logon Background Changer allows any user to change the logon background of Windows 7 by just selecting a folder, picking an image, and it’s done. It doesn’t even requires an installation.
Julien also made available the application source code, written in C#.NET using VS2008.
You can find out more about Julien application at his own website.
Wolfram|Alpha Homework Day
Excitement is building as we count down to our first-ever
Wolfram|Alpha Homework Day, a live interactive web event starting
at noon CDT on Wednesday, October 21, 2009.This event is dedicated to showing how Wolfram|Alpha, a
groundbreaking free website, is a powerful new discovery and
learning tool for students, parents, and educators.We are proud to announce today some of the highlights we have
planned for Homework Day, including:
* Several interactive segments where Stephen Wolfram and the
Wolfram|Alpha Team help you tackle tough homework problems
* Step-by-step tutorials for educators by educators demonstrating
how to integrate Wolfram|Alpha into the classroom
* Vibrant panel discussions about Wolfram|Alpha and the future of
education
* And lots moreMore details about Homework Day and how you can participate are
available on the Wolfram|Alpha Homework Day home page:http://homeworkday.com
We hope you will check out the site and save the date for
Wolfram|Alpha Homework Day on Wednesday, October 21, 2009.Best regards,

Wolfram|Alpha?

Ever heard of Wolfram|Alpha?
Released on May 15, 2009, Wolfram|Alpha is a recent answer engine developed by the Wolfram Research. It is an online service that aims to make all systematic knowledge immediately computable and accessible to everyone by computing the answer from structured data.
We aim to (…) make it possible to compute whatever can be computed about anything.
(…)
our goal is to create something that will stand as a major milestone of 21st century intellectual achievement.
At a first glance, Wolfram Alpha seems a very useful and an extraordinary project. For example, if you type “Ohm Law”, it immediately shows you the equation and it’s meaning, as well as a converter/calculator. If you type the name of a city, it shows you a map and a bunch of statistic and values (population, weather…) related to that same city.
It really is something to keep an eye on and take a look at. Try typing a domain name, a celebrity name, a date, a song,…anything.
It seems a fantastic project and I’m hoping that Wolfram Research goals will be successfully accomplished, since that means everyone wins…well almost everyone.

WPF – How to restart my application?
Unfortunately, to date, WPF does not have a Restart() function line in WinForms so one way to do this is by using…WinForms.
1 | System.Windows.Forms.Application.Restart(); |
However, after running this code our application will not exit on it’s own, even though a new instance of the application is being created. Therefore, we must close it manually…for example by doing:
1 | Application.Current.Shutdown(); |
If you don’t want to use WinForms with your application you can do something like:
1 2 3 4 5 | //things to do before closing // ... //Restart System.Diagnostics.Process.Start(Application.ResourceAssembly.Location); Application.Current.Shutdown(); |
Where we create a new instance of our application, by using Process.Start, and immediately close the current one.
