Almost everybody who works with computers keeps a journal of tips, shortcuts and solutions relevant to their environment. This just happens to be mine.
I had been blogging sporadically since 2004. In 2008 when I was learning Python I started taking notes on my blog every day. I guess I never stopped after that.
In a happy coincidence, many people seem to have found this journal useful, driving up the views on this blog to the millions. If you are one of those people, I am happy to have helped you.
