Failed to install Python Cryptography package with PIP and setup.py
... ships manylinux wheels. This means users with pip 8.1+ running on a glibc-based distribution (almost everything except Alpine Linux) and on x86/x86-64 no longer need a compiler or headers because you'll get a precompiled wheel automatically. With version 3.1 we now also ship aarch64 wheels (which r...
Why would introducing useless MOV instructions speed up a tight loop in x86_64 assembly?
...ain, but can be avoided by using dependency breaking idioms. In processors based on Intel Core micro-architecture, a number of instructions can help clear execution dependency when software uses these instruction to clear register content to zero. Break dependencies on portions of registers between ...

What is time_t ultimately a typedef to?
...en read by other operating systems, it'd be silly to define the filesystem based on such implementation-dependent types. For example, the same filesystem might be used on both 32-bit and 64-bit systems, and time_t might change size. Thus, filesystems are need to be defined more exactly ("32-bit sign...

// We can use it to define limits based on actual compiler built-in types also:

...is returned to the generator's caller. It can be thought of as a generator-based version of the return keyword.
A generator allows you to suspend execution of a function and resume it later. A generator can be used to schedule your functions with a technique called trampolining.
Here is the examp...
