Proxy servers from a .net developers perspective
I was wondering if anyone can recommend a good book / web site / blog or article (anything!) that can help demystify the proxy, not in terms of its use as a product, but purely from a .net developers point of view.

We've noticed some strange Cursor behavior, which we suspect is a result of one of our Cursor canging methods. Just sometimes, our pc keeps showing the SizeAll cursor. Everywhere, in every application. Now, we never use the SizeAll cursor anywhere in our code, but we can "Unstuck" the cursor when following code is executed. We suspect t...
Compare two list elements with LINQ
I'm trying to find a LINQ expression to compare two list elements. What i want to do is: List<int> _int = new List<int> { 1, 2, 3, 3, 4, 5}; _int.Where(x => x == _int[(_int.IndexOf(x)) + 1]); Unfortunately, only the last +1 jumps out of the list's range. How can I compare one item with its next in the list in a LINQ expression? ...

Using many System.Timers.Timer objects
I have an application which makes use of System.Timers.Timer objects to do expirations and email notifications and such.
