... to the difference between the two sets, the C++ standard mandates minimum ranges for each, and that long long is at least as wide as long.
The controlling parts of the standard (C++11, but this has been around for a long time) are, for one, 3.9.1 Fundamental types, section 2 (a later section gives...

What is the theoretical maximum number of open TCP connections that a modern Linux box can have
...
If you used a raw socket (SOCK_RAW) and re-implemented TCP in userland, I think the answer is limited in this case only by the number of (local address, source port, destination address, destination port) tuples (~2^64 per local address).

At the same time, it's really easy to publish solutions, and download those published by others through npm. Don't expect a lot of smarts from Node itself. Instead, expect to find the smarts in packages publish...

...actually looks at (and it skips many

GNU grep uses raw Unix input system calls and avoids copying data

Getting a map() to return a list in Python 3.x
...atin-1 is to do bulk conversions at the C layer: bytes(sequence_of_ints_in_range_0_to_256).decode('latin-1') which makes a str faster by avoiding Python function calls for each element in favor of a bulk conversion of all elements using only C level function calls. You can wrap the above in list if ...
