MethodImplOptions.InternalCall
That means that the method is actually implemented in the CLR, written in C++. The just-in-time compiler consults a table with internally implemented methods and compiles the call to the C++ function directly.

When and why would you seal a class?
...
I meant be careful with sealing classes in reused libraries, especially if they're beind reused by third parties and then reintegrated (via MEF) into the codebase. Your codebase may not inherit a given class but third parties w...

On Python 3.4+ you can use statistics.mean()
l = [15, 18, 2, 36, 12, 78, 5, 6, 9]
import statistics
statistics.mean(l) # 20.11111111111111
On older versions of Python you can do
sum(l) / len(l)
On Python 2 you need to convert len to a float to get float d...

Draw something with it - glDrawArrays(GL_TRIANGLES, 0, 6);
The next thing you draw may not use attribute 0 (realistic...
MPICH vs OpenMPI
...ICH and many of its derivatives support ABI compatibility (website), which means that the binary interface to the library is constant and therefore one can compile with mpi.h from one implementation and then run with another. This is true even across multiple versions of the libraries. For example...
How does HashSet compare elements for equality?
...se IEqualityComparer<T>.Equals to compare for actual equality.
That means you have two options:
Pass a custom IEqualityComparer<T> into the constructor. This is the best option if you can't modify the T itself, or if you want a non-default equality relation (e.g. "all users with a neg...
