• after each article I hear “Adiós” from those who lower my karma to minus, but literally a couple of days later they return my right to write
• I was advised not to talk about my karma in the article, since it is “obviously dangerous”, even more dangerous than the mention of the word “hamsters” “lemmings”
• very soon there will be a series of articles on how to write a blog management system in pure php 5.3 and xhtml 1.1 from scratch
• Download a dump of user databases, here
• data obtained using phpQuery , the article is written using chartle.net and bankinform.ru
