Swift equivalent for MIN and MAX macros
...ou can use it like this with Floats:
let maxInt = max(12.0, 18.5, 21, 26, 32.9, 19.1) // returns 32.9
With Swift however, you're not limited to use max(_:_:) and its siblings with numbers. In fact, those functions are generic and can accept any parameter type that conforms to Comparable protoco...

Average of 3 long integers
...
I would suggest that a good way of dividing a 32-bit unsigned value by 3 is to multiply by 0x55555555L, add 0x55555555, and shift right by 32. Your divideby3 method, by comparison, looks as though it would require many discrete steps.

No ConcurrentList in .Net 4.0?
...th relatively slight added overhead. When the list expands from e.g. size 32 to 64, keep the size-32 array and create a new size-64 array. When adding each of the next 32 items, put it in slot a 32-63 of the new array and copy an old item from the size-32 array to the new one. Until the 64th item...
Why do we need boxing and unboxing in C#?
... can only be primitive values, like a bool, a byte, a 32-bit int, a 32-bit uint, etc. The Stack is both simple and fast. As variables are added they just go one on top of another, so the first you declare sits at say, 0x00, the next at 0x01, the next at 0x02 in RAM, etc. In addition, variables are o...

What is the difference between an int and a long in C++?
...which has to fit within INT_MIN and INT_MAX.
The C89 standard states that UINT_MAX should be at least 2^16-1, USHRT_MAX 2^16-1 and ULONG_MAX 2^32-1 . That makes a bit-count of at least 16 for short and int, and 32 for long. For char it states explicitly that it should have at least 8 bits (CHAR_BIT...
EntityType has no key defined error
...blic
The key needs to be a CLS-compliant type, meaning unsigned types like uint, ulong etc. are not allowed.
This error can also be caused by configuration mistakes.
