We, as a society, have become too easily distracted. We are all suffering these days from lack of focus, and it could get worse. “TMI” stands for “too much information,” and it is too much information that contributes to our... Read more

There’s Nothing Like Real Experience: I
As the saying goes, the point on a pencil is the inspiration and the other end with the eraser is the experience. A pencil without an eraser is next to useless, as I have found out. Yes, I know that,... Read more

Written Communications
No matter if an engineer did the best job in the world with a design, if the person responsible for the design cannot communicate the design effectively, then the design effort was wasted. That’s the reason that I gave to... Read more
