Welcome to my blog. It’s an eclectic mix of stuff I’m interested in – i.e. nerdy stuff. But you have to think also that it’s “old guy” nerdy stuff.
Frankly, even though I’m an old nerd, I probably wouldn’t read this. (How’s that for a come-on?)
On the other hand, I’ve been doing this for a few years, and it turns out a variety of people find at least some of it interesting. If you are a variety of people, you will probably find things of interest yourself.
This is my second time to build a blog. The first one had lots of technical limitations that frustrated me. Now I’m using a WordPress web site and, so far, I’m very happy and haven’t run across anything I couldn’t make happen.
One of the best things is the ability to show just the beginning of a blog entry so you can quickly decide if it’s for you. Not only that, but you can skim through scads of blogs in a hurry to find what you like.
So jump in.
This is the time of year that folks back in my old hometown of Geneva, Alabama, keep a close eye on the river level. Most of the severe floods have occurred in March, but April is in second place.
It’s important to keep an eye on the rainfall above Geneva, not just around town. This map clearly shows why. Heavy rain in Dale, Pike, or Barbour counties means trouble for folks who live near the junction of the Pea and Choctawhatchee rivers.
If you’re one of those people, or just have an interest in this sort of thing, take a look at the Advanced Hydrologic Service of the National Weather Service.
Live near a river? They probably have coverage for you, too.
Here’s my favorite example of something that is counterintuitive. If you shoot a handgun with a light, fast bullet, and then shoot the same gun with a heavy, slow bullet, which one will hit the target higher?
I think all of my elementary school teachers had a world “globe” map in their rooms. They varied from modest to “not bad” table models. At the library downtown, there was an even bigger one on a floor stand.
I doubt if it was as nice as the one above, but it was a fascinating thing to me.
All of these globes had one feature that was a great mystery. It was almost always in the middle of the Pacific Ocean and it looked like a big, skinny Continue reading
Here is some valuable information (and an excellent example of the relative nature of “value”).
The speed of sound depends on air temperature.
That’s it. It does not depend on altitude or air density or moisture content or anything else. Just temperature.
So how fast is the speed of sound?
Sometime in the late 50′s I joined the Columbia LP Record Club™. If you’re old enough to remember, you probably belonged, too. It was an exciting way for a kid in the middle of Nowhere, Alabama, to acquire some

LightRoom is my favorite photo program. I use it much more than PhotoShop. Both come from Adobe and both are the best at what they do.
For most photos, LightRoom will do all Continue reading
My sharp-eared friend John pointed this out to me back in 1962. We worked together at the little radio station in our home town. He was older and much wiser, and my mentor and big brother rolled into one. At one time, he was pretty much the top engineer at ABC (the broadcasting empire).
Smart fellow. Continue reading
