\section*{What is this?}

This a collection of notes gathered here with an aim to offload my other books (\REBK and \SSBE) from mathematical theory,
which still can be of interest for a general audience of programmers.

It can be said, this is a \textit{companion book}.

Also, random posts from my blog.

So, nothing special.

Started in August-2015.
