Notice: Comments have been turned off due to excessive spam

I’ve been getting upwards of 50 or more spam messages a day on this blog in spite of using Captcha and other devices so I am going to turn off comments for the time being.  Please feel free to email blog-related comments directly to me at pknox @  Sorry for this inconvenience but it is taking too much time to moderate; I would rather spend the time providing more blog postings.
