When would anyone use a union? Is it a remnant from the C-only days?
...neral endianness interface to an unknown external host.
Manipulate foreign CPU architecture floating point data, such as accepting VAX G_FLOATS from a network link and converting them to IEEE 754 long reals for processing.
Provide straightforward bit twiddling access to a higher-level type.

Java “Virtual Machine” vs. Python “Interpreter” parlance?
...ndbox unto itself. The VM is analogous to an instruction set of a specific CPU and tends to work at a more fundamental level with very basic building blocks of such instructions (or byte codes) that are independent of the next. An instruction executes deterministically based only on the current stat...
What is uint_fast32_t and why should it be used instead of the regular int and uint32_t?
...han 32-bit? I always thought if there's less bits, there will be less bits CPU has to work on, thus faster. What am I missing here?

Why are elementwise additions much faster in separate loops than in a combined loop?
...
OK, the right answer definitely has to do something with the CPU cache. But to use the cache argument can be quite difficult, especially without data.
There are many answers, that led to a lot of discussion, but let's face it: Cache issues can be very complex and are not one dimension...
