From time to time you need to deep dive into a subject and you need a good site to read about it.
Over the years I have come across many such sites, and this is my attempt to collect them in a single place.
I have revisited the some of the same subjects, but since searching the web has become a worse
and worse experience, finding them again has been almost impossible.

I hope to make this list as long as all the sites I want to put here. Also, I'll be using 
[Archive.org's](https://archive.org/) links, to make sure you can find them even if the sites are down.
