Regular readers of this blog are well aware that my blogging activities sort of ran off the rails in early April and that my blog posts since then can be counted on the digits of one hand—with a couple of thumbs to spare. Getting my various projects back on the rails and back up to speed has been a long, slow process, so when Barbara O’Brien (The Mahablog) asked me if I could post one of her articles on my other blog (Petey’s Pipeline) I readily agreed. I might be too proud to ask for help, but that doesn’t necessarily mean that I’m too proud to accept help if it’s offered.
