Clear introduction to atomics and lock-free programming

Jeff Preshing gave a really good introduction to atomics at CppCon 2014.[1] He explains it so clearly that 1 day later I had a fully tested lock-free work stealing queue and a queue. One of my favorite talks of last year. [1]: [this video]

Ubisoft talk going deep on atomic ops, compared with Naughty Dog's

Similar talk: CppCon 2014: Jeff Preshing "How Ubisoft Develops Games for Multicore - Before and After C++11" [this video] Ubisoft's talk spends more time getting into the weeds with atomic ops. Naughty Dog's is more of an architecture discussion. If you can only watch one, I'll recommend Naughty Dog's.

And after i figured it out, i found a talk from an Ubisoft employee that is mostly what i came up with. The problems are many, especially since i want to support multiplayer. The biggest solutions are around how data is transformed and scheduling the code that transforms it, more or less. The talk: [this video]
