An endless tiny project of documenting of thoughts which strike author from time to time while working. Owing to their shortness they can't be considered as articles. And that's why it was decided to collect them into a kind of virtual handbook that is useful for author himself first of all, and may give somebody the benefit of author's experience.
Though any idea here was dictated by experience and common sense, it solely voices author's opinion.
The author is Alexander Zubkov.
