If you enjoy this article, I highly recommend the other articles in the archives [1], especially the 2008-2009 series.

By the way, the author also created Grokbit [2], a search engine for source code that's just… amazing.

Note to self (and anyone else): check out https://grokbit.com after all the traffic from this post gets handled.

Looks like it (attempts to) serve a very popular need. Time to bring my side-project up a couple of notches.

Any similar online resources describing low level operations in such detail?

For Linux at least, have a look at resources on kernel.org:

eg. https://www.kernel.org/doc/gorman/html/understand/understand...

or https://www.kernel.org/doc/Documentation/vm/

“Professional Linux Kernel Architecture” by Wolfgang Mauerer is also a great read.

And don't forget hardware vendors' documentation, such as http://developer.amd.com/wordpress/media/2012/10/24593_APM_v... (there's much more in it than just assembly instructions)

Thanks for the share.. I was just reading about asynchronous io this weekend.
