COSS BI: Open Source, Open Core or Openly Naked?
Peter Yared wrote recently a BusinessWeek guest blog post called “Failure of Commercial Open Source Software.” Not surprisingly his post caused a lot of angry replies from people who work for COSS companies. “The emperor is not naked” they argued.

Using Microsoft’s Chart Controls In An ASP.NET Application: Adding Statistical Formulas
The Microsoft Chart controls make it easy to take data from a database or some other data store and present it as a chart. As discussed in Plotting
Chart Data, the Chart controls offer a myriad of ways to get data into a chart. You can add the data programmatically, point-by-point, or you can bind an ADO.NET DataTable
directly to the Chart. You can even use declarative data source controls, like the SqlDataSource or ObjectDataSource controls.
In addition to converting your specified data points into a chart image, the Chart controls also include a wealth of statistical formulae that you can use to analyze the plotted data. For example, with a single line of code you determine the mean (average) value for data in a particular series. Likewise, with one line of code you can get the median, variance, or standard deviation. These values can be displayed as text on the page or as a stripe line on the chart itself. What's more, the Chart controls include functions to forecast future values, to compute moving averages, to identify trends, and to determine rates of change, among others.
This article looks at how to use two statistical formulae. Specifically, we'll look at how to compute and display the mean of a series, as well as how to display an exponential
trend line on the chart to forecast future values. Read on to learn more!

Silverlight Virtual Twilight Tour
In anticipation of the opening of the Twilight Saga: New Moon movie on November 20th, MSN has created a Virtual Twilight Tour. Created entirely in Silverlight 3 - from the video player to the map interface - the Tour brings Forks, La Push, Port Angeles, and Volterra right to your computer so that you can see 16 of Twilight’s and New Moon’s most exciting locations.
MSN built the Tour using Visual Studio and Visual C#, employing the Bing Maps control for location-based navigation. For the ‘bells and whistles,’ Expression Blend helped to create the animations that transition the user from one action to another. The end result is a seamless multimedia interaction. Just scroll over the map to check out the video, photos, audio, and contextual Bing searches for the full tour experience.
