Most programmers have an intimate understanding of CPUs and sequential
programming because they grow up writing code for the CPU, but many are
less familiar with the inner workings of GPUs and what makes them so
special. Over the past decade, GPUs have become incredibly important
because of their pervasive use in deep learning. Today, it is essential
for every software engineer to possess a basic understanding of how they
work. My goal with this article is to give you that background. read more...
Traditionally, Unix/Linux/POSIX filenames can be almost any sequence of bytes, and their meaning is unassigned. The only real rules are that "/" is always the directory separator, and that filenames can't contain byte 0 (because this is the terminator). Although this is flexible, this creates many unnecessary problems. In particular, this lack of limitations makes it unnecessarily difficult to write correct programs (enabling many security flaws), makes it impossible to consistently and accurately display filenames, causes portability problems, and confuses users. more ....
