One of the readers took me task over the last couple of postings - and rightfully so. Since mid February I have been traveling extensively and pressed to keep this blog current while on the road. In my haste to keep content flowing I made several posts that were plainly just sloppy. Punctuation and spelling, like for many engineers, is not my strong suit. I usually rely on Microsoft Word to help me proofread my material. For the last couple of posts I just typed them into the blogging tool we use. Unfortunately it does not alert me to potential errors like Word does.
