Thread pooling in C++11
...r function with an infinite loop, constantly waiting for new tasks to grab and run.
Here is how to attach such function to the thread pool:
int Num_Threads = thread::hardware_concurrency();

Inherit from a generic base class, apply a constraint, and implement an interface in C#
...tion. I have a generic class which is inheriting from a generic base class and is applying a constraint to one of the type parameters. I also want the derived class to implement an interface. For the life of me, I cannot seem to figure out the correct syntax.

How to detect if a function is called as constructor?
...
NOTE: This is now possible in ES2015 and later. See Daniel Weiner's answer.
I don't think what you want is possible [prior to ES2015]. There simply isn't enough information available within the function to make a reliable inference.
Looking at the ECMAScript 3...

Concurrency and simultaneity
I/O operations interact with the environment. The environment is not part of your program, and not under your control. The environment truly exists "concurrently" with your program. As with all things concurr...

Average of 3 long integers
...ides all three values (it floors the values, so you 'lose' the remainder), and then divides the remainder:
long n = x / 3
+ y / 3
+ z / 3
+ ( x % 3
+ y % 3
+ z % 3
) / 3
Note that the above sample does not always work properly when h...
Detecting Browser Autofill

The problem is autofill is handled differently by different browsers. Some dispatch the change event, some don't. So it is almost impossible to hook onto an event which is triggered when browser autocompletes an input field.

Why does Boolean.ToString output “True” and not “true”
Is there a valid reason for it being "True" and not "true"? It breaks when writing XML as XML's boolean type is lower case , and also isn't compatible with C#'s true/false (not sure about CLS though).
