Changing the user profile path in Windows 7

Posted on Thu 12 July 2012 in Sysadmin • Tagged with profile, windows7

Nothing programmatic about this post, unfortunately.

I just ran into a tiny little problem and thought I’d share the solution.

Nothing surprises me in VB.NET

Posted on Tue 27 March 2012 in Coding • Tagged with nothing, null, vb.net

I currently work in a VB.NET project with a customer, and what amazes me is that I over and over again get the feeling that the language is designed to be easy to work with, but at the same time there are so many aspects of it that behave ...

NSubstitute vs Moq - a quick comparison

Posted on Mon 27 February 2012 in Coding • Tagged with mock, moq, nsubstitute, test
