This blog has been inactive for the last four months or so. Following that vacation, other work and preparation for retirement has pushed blog updating aside. I retired last week, but I am still sorting documents from more than forty years. I hope to resume blog entries shortly.
Retirement resolution: I must not post to this blog late at night. That leads to corrections, then corrections to corrections. And I think I may need to consider corrections to corrections to corrections when I resume blogging!
June 2011: this temporary absence has continued, to avoid any conflict arising due to prior publication here of any material which may form part of a publication in preparation. Previous posts have focussed on a very specific area, so perhaps a post on another topic is now long overdue! I have something in mind, so perhaps I can post again before that publication is ready for submission.
