IIS7 deployment - duplicate 'system.web.extensions/scripting/scriptResourceHandler' section
... running in .net 4.0 you will need to cleanup the web.config that includes all the section Definitions that point to .net 3.5. The reason this fails is because these section definitions are already included in the root web.config in .NET 4.0 (see %windir%\microsoft.net\framework\v4.0.30319\config\ma...
Is using Random and OrderBy a good shuffle algorithm?
...asy to implement an O(n) shuffle. The code in the question "works" by basically giving a random (hopefully unique!) number to each element, then ordering the elements according to that number.
I prefer Durstenfield's variant of the Fisher-Yates shuffle which swaps elements.
Implementing a simple S...
What happens if I define a 0-size array in C/C++?
Just curious, what actually happens if I define a zero-length array int array[0]; in code? GCC doesn't complain at all.

Remove Elements from a HashSet while Iterating [duplicate]
...
You can manually iterate over the elements of the set:
Iterator<Integer> iterator = set.iterator();
while (iterator.hasNext()) {
Integer element = iterator.next();
if (element % 2 == 0) {
iterator.remove();

Use variable with TOP in select statement in SQL Server without making it dynamic [duplicate]
...
SQL Server 2005 actually allows us to parameterize the TOP clause, using a variable, expression or statement. So you can do things like:
SELECT TOP (@foo) a FROM table ORDER BY a
SELECT TOP (SELECT COUNT(*) FROM somewhere else) a FROM table ...

What is an “unwrapped value” in Swift?
...st, you have to understand what an Optional type is. An optional type basically means that the variable can be nil.
Example:
var canBeNil : Int? = 4
canBeNil = nil
The question mark indicates the fact that canBeNil can be nil.
This would not work:
var cantBeNil : Int = 4
cantBeNil = nil // can...
How do I put two increment statements in a C++ 'for' loop?
...us:
for(int i = 0; i != 5; ++i,++j)
do_something(i,j);
But is it really a comma operator?
Now having wrote that, a commenter suggested it was actually some special syntactic sugar in the for statement, and not a comma operator at all. I checked that in GCC as follows:
int i=0;
int a=5;
int...
Never seen before C++ for loop
...#. In my opinion it is clearer, less of a trap for new programmers, and equally efficient.
As others have pointed out -- but to make my answer complete -- to make it work in C# you would need to change while(u--) to while(u-- != 0).
... or while(u-- >0) just in case u starts off negative. (OK, ...
