An apology

I am aware that the gap in the postings has been wider than ever and the reason for that is purely technical. I was having very serious problems with unwanted advertising that swamped websites and, in particular, Blogger whenever I wanted to use it. The problems have been solved (D. V.) and I shall re-start blogging in a very short time, possibly hours. I'd like to think that I have spent the intervening period in cogitating about the nature and purpose of this blog.
