=> strlcpy and how CPUs can defy common sense [NRK]

A nice analysis of how scanning a string twice (‘strlen’ + ‘memcpy’) can be faster than scanning it once (‘strlcpy’).

Also contains a link to a fun (possibly made up?) quote from Tony Hoare in a discussion with Nico Lomuto.

Computers do not have common sense. Computers are surprising.
