In order to open this blog to public access I had to sanitize its content. But of course it is not possible to suppress ideas that are only in the reader’s mind. So, reader, beware! You will not find here more, or less, than I intended to write or show. Anything else is the fruit of your imagination.
Notes here included are mainly for my personal usage, with no practical use whatsoever for someone else. They have mainly a technical nature, in the sense that technics precede science.
