Numerical Perspective

I’m just some guy who’s blogging as a hobby, so it’s interesting to check the month-end numbers. Excluding all traffic from home, and rounding down to be conservative, in October there were 92,000 hits on DogRat.com from 4900 unique addresses.

Plastic Soul Lives

On October 17, Amazon.com created a section devoted to vinyl records.

One of D.F. Rogers’ possessions that I envy him having is the complete British catalog (or, should I say, “catalogue”) of Beatles albums put out by Mobile Fidelity Sound Labs in the early 1980’s. The box set now goes for big bucks on eBay. I have a couple of the individual discs. The general consensus is the records sound better than the CDs; which is understandable, considering the digital mastering was done with first-generation equipment over 20 years ago.

GE RCA Superadio III

When I was a boy I loved my Aiwa TP-32A reel tape recorder, but the single most satisfying piece of electronic equipment I’ve ever owned is a GE Superadio III. I bought it for $40 in November, 1994, and today it gets regular use sitting in the window next to my computer.

HD Radio and Wi-Fi Radio are coming along, and there’s satellite radio of course, but plain, old AM/FM radio remains convenient and reliable. And the Superadio III, having analog tuning, is about as plain as it gets. What sets it apart is its exceptionally good, albeit mono, sound quality.

Recently, the company that makes the Superadio III, Thomson of France, changed the brand name from GE to RCA. Or maybe it’s being made by another outfit. Whatever. The product seems to be pretty much the same as it’s been for nearly 15 years. It remains the absolute cheapest self-contained hi-fi audio system that I know of.

Digi-Comp 1 — The First Home Computer

When I was a kid, it bothered me that most people were more interested in the ads in comic books than in the stories. Most of what was sold was junk, of course — the notorious X-Ray Specs for example — but once in a while a legitimately interesting product was offered. So, in acknowledgment of that, here’s an ad from a 1967 Marvel comic book. It’s the Digi-Comp 1!

If not exactly the first home computer, the Digi-Comp 1 was a working binary counting machine. Here’s a Digi-Comp 1 in action, counting from 0 to 7 in binary. It’s even done twice, in case you miss it the first time. 😉

Exciting, huh? But compared to the comic book ad the Digi-Comp 1 must have been a disappointment. First, there’s nothing electronic about it, and the atomic symbol would seem to imply it’s nuclear in some way. But at least the Digi-Comp 1 is described accurately as being a “mechanical analog of a binary computer.”

I hope the person who wrote the ad copy didn’t use a Digi-Comp 1 to figure out the price, because it’s listed first at $4.99, then in the coupon at $4.98. Oh well, they didn’t claim “down to the penny precision!”

The Digi-Comp 1 has, as you might expect, something of a cult following. Original units are often auctioned in eBay, and there is a replica of it available at Minds on Toys.

NOVA: Marathon Challenge

October 30, the evening after American Masters shows the Charles Schulz program, NOVA on PBS will present Marathon Challenge.

NOVA wanted to investigate these questions through the “Marathon Challenge,” and with the help of a dozen enthusiastic recruits, we set out to see if “ordinary people” could transform themselves into marathoners in just a matter of months. The results were extraordinary.

The timing of this program is interesting, because a runner died in the Chicago Marathon this past Sunday; not from the 84° heat, but from a pre-existing heart condition. I have completed six Boston Marathons, under a wide variety of weather conditions, including a day when the temperature hovered around 90°F. And take it from me, it’s not something you want to try unless you’re totally in love with the idea of doing it and are prepared to do the work to get ready.

Does the idea of heading out the door to run 16 miles, even when it’s raining, because that’s what the training schedule says to do, appeal to you? No? Then forget marathon running.

The NOVA participants benefited from expert guidance throughout their 40-week training — hmm… the same number of weeks it takes to have a baby. The idea that anybody can run a marathon is simply wrong. Jon Krakauer is a favorite author of mine, and in his book Into Thin Air he is critical of people who want to believe that anybody can conquer climbing Mt. Everest with proper training and adequate equipment.

WALKING the Boston Marathon course is do-able, with proper preparation. A good friend of mine did exactly that recently. But if you aren’t already a runner, and you’re more than ten pounds overweight, and you’ve never jogged more than three miles, I strongly suggest that you not get it in your head that 26.2 miles is nothing more than 13.1 miles times two, because doubling the effort it takes to do 13.1 miles occurs at about 19 miles. And you still have another 7 miles to go.
