Best practices for circular shift (rotate) operations in C++
...motion rules mean that rotl_template(u16 & 0x11UL, 7) would do a 32 or 64-bit rotate, not 16 (depending on the width of unsigned long). Even uint16_t & uint16_t is promoted to signed int by C++'s integer-promotion rules, except on platforms where int is no wider than uint16_t.
On x86, th...

...ses a multiplicative linear congruential generator (MLCG) with c=0 and m=2^64. (The modulus 2^64 is implicitly given by the overflow of 64bit long integers)
Because of the zero c and the power-of-2-modulus, the "quality" (cycle length, bit-correlation, ...) is limited. As the paper says, besides the...
How to update Python?
...ow, these answers are for the same bit-versions, and by bit-version I mean 64-bit vs. 32-bit. For example, these answers would apply to updating from 64-bit Python-2.7.10 to 64-bit Python-2.7.11, ie: the same bit-version. While it is possible to install two different bit versions of Python together,...
