No ConcurrentList in .Net 4.0?
...
The biggest scenario where a ConcurrentList would be a win would be when there isn't a whole lot of activity adding to the list, but there are many concurrent readers. One could reduce the readers' overhead to a single memory-barrier (and eliminate even that if readers weren't c...
What's the difference between EscapeUriString and EscapeDataString?
... Exactly right. EscapeUriString (like EscapeUrl's default behavior in Win32) was created by someone who didn't understand URIs or escaping.

I tried hard and got the following code to output different text for each of those forms, without using the "obvious" through explicit constructors.
#include <iostream>

struct A {
operator B();

Iterator Loop vs index loop [duplicate]
I'm reviewing my knowledge on C++ and I've stumbled upon iterators. One thing I want to know is what makes them so special and I want to know why this:
