I have a recollection of reading something along those lines in your blog some years ago as well, and I suspect that latent memory is what gave me the idea. Perhaps when I have some time I’ll do some more searching for that one. -Alex P.S. I should also say thanks for your writings. As someone who doesn’t do this kind of thing as a regular profession, I’ve found your articles both entertaining and highly informative over the years. Alex Johnson ax.john...@gmail.com
