My draft, half-baked, not duly prepared notes

Untranslated (yet?) notes in Russian language marked with "RU" suffix in filename. Of course, these are in UTF-8 encoding.

.org-files - Emacs org-mode format.

I would be very grateful for (early) feedback on my notes. Please tell me about any bugs, mistakes, typos, etc. This is very important for me. My emails
