What is uint_fast32_t and why should it be used instead of the regular int and uint32_t?
...bits on some platforms. It may not be sufficient for your application.
uint32_t is not guaranteed to exist. It's an optional typedef that the implementation must provide iff it has an unsigned integer type of exactly 32-bits. Some have a 9-bit bytes for example, so they don't have a uint32_t.
uint_f...

What is the memory consumption of an object in Java?
...ded to a multiple of 8 bytes, so the minimum object size is 16 bytes. For 32-bit JVMs, the overhead is 8 bytes, padded to a multiple of 4 bytes. (From Dmitry Spikhalskiy's answer, Jayen's answer, and JavaWorld.)
Typically, references are 4 bytes on 32bit platforms or on 64bit platforms up to -Xmx...
Why is creating a new process more expensive on Windows than Linux?

When discussing the speed of process creation, it is probably a good idea to distinguish between NT an...
