by Dwayne Phillips Somewhere, somehow we forgot what a good approximation was. We used to tell this “joke” a long time ago in a place far, far away. Consider the situation with an amorous young gentlemen on one side of a room and an amorous young lady on the other side of the room. Every […]

How Did We Mess Up This One?
August 15th, 2019 · No Comments
by Dwayne Phillips Really smart persons continue to blunder. How? I read this article recently about how women are hurt more often and more severely than men in automobile accidents. Why does this happen? The crash dummies used in safety tests work well, but are almost always the size and shape of a man. Crash […]

The Clipboard and the Pencil…and the Database
June 20th, 2019 · No Comments
by Dwayne Phillips Before embarking on a new database, or any new system, learn what it is we want and need. “Let’s create a database to track this,” said an eager and well-meaning person. “But,” interjected another well-meaning person, “do we know what we need or want or anything?” My livelihood has been technology. Of […]

The Bend in the Curve(s)
June 6th, 2019 · No Comments
by Dwayne Phillips When will the curve bend? When should I change? Will I be willing to change? There are curves we can draw that show cost, performance, and lots of things. Take note of them. Take note of the bend in the curve… when USB thumb drive air gap is faster than a network […]
The Database and the Floor
May 2nd, 2019 · No Comments
by Dwayne Phillips Take care how we state the requirements for a database. A spot on the floor often meets the requirements. I attended a meeting recently wherein a senior official with a long, impressive title stood in front of a crowd of several hundred persons and spoke at length (three hours). A major part […]

Small Wheels, High Center of Gravity, and Physics
March 4th, 2019 · No Comments
by Dwayne Phillips Once again, we observe that physics—notably gravity—wins. Sometimes I venture outside the suburbs of Federal Virginia go into “downtown” Washington D.C. I see them, those funny-colored little skateboards with handles. These are the eScooters or whatever we choose to call them this week. They have little electric motors and speed pedestrians (I […]

February 25th, 2019 · No Comments
by Dwayne Phillips No new materials. A simple pressing. Structure appears. Value from almost nothing. This is a primary task of a manager (and the rest of us). Fold something. Press the fold. It becomes a crease. And now there is a structure that has strength and increased utility. And how did that happen? A […]

Please Remove Your Sticker from My Car
January 31st, 2019 · No Comments
by Dwayne Phillips We tend to allow others to use us freely. A simple example. About every ten years I buy a new automobile. Yes, I am “cheap,” and yes, today’s automobiles are built well enough to drive efficiently for ten years or more. After buying my last automobile, I arrived at home and noticed […]

Lack of Focus, Lack of Foresight
June 7th, 2018 · No Comments
by Dwayne Phillips Jumping from one thing to the next may appear to be a lack of focus when it really is a lack of foresight. We’re working on this great thing. It took longer than we thought to build it. As we came close to finishing, rats, we quit because we realized that this […]
