Mintomic is a very small part in all the blog posts (anyway it is not used anymore).
The C++11 atomics are largely covered.
It is for me the best resource for beginners (easier at start that the Anthony Williams book for instance).
My opinion is probably biased since i learned all (at first) with that blog!
