For those who are interested in programming, an excellent development tool is #develop.

#develop (short for SharpDevelop) is a free IDE for C#, VB.NET and Boo projects on Microsoft's .NET platform. It is open-source, and you can download both sourcecode and executables from the site.

This is an excellent replacement for Microsoft Visual Basic in the .Net environment. It can be made portable as I carry a version on my flashdrive for work away from home.

I would like to see LiberKey begin a new category for development tools of which this would make a great start.

Here is a tutorial to make it portable: http://laputa.sharpdevelop.net/SharpDev ... Stick.aspx

SharpDevelop is a open source IDE for .net.
