A long time ago I wrote about secret government telephone numbers, and before that, secret military telephone buttons. I suppose this is becoming a series. To be clear, the "secret" here is a joke, but more charitably I could say that it refers to obscurity rather than any real effort to keep them secret. Actually, today's examples really make this point: they're specifically intended to be well known, but are still pretty obscure in practice. If you've been around for a while, you know how m...| computers are bad
Some time ago, via a certain orange website, I came across a report about a mission to recover nuclear material from a former Soviet test site. I don't know what you're doing here, go read that instead. But it brought up a topic that I have only known very little about: Hydronuclear testing. One of the key reasons for the nonproliferation concern at Semipalatinsk was the presence of a large quantity of weapons grade material. This created a substantial risk that someone would recover the mate...| computers are bad
Sometimes I think I should pivot my career to home automation critic, because I have many opinions on the state of the home automation industry---and they're pretty much all critical. Virtually every time I bring up home automation, someone says something about the superiority of the light switch. Controlling lights is one of the most obvious applications of home automation, and there is a roughly century long history of developments in light control---yet, paradoxically, it is an area where ...| computers are bad
Air traffic control has been in the news lately, on account of my country's declining ability to do it. Well, that's a long-term trend, resulting from decades of under-investment, severe capture by our increasingly incompetent defense-industrial complex, no small degree of management incompetence in the FAA, and long-lasting effects of Reagan crushing the PATCO strike. But that's just my opinion, you know, maybe airplanes got too woke. In any case, it's an interesting time to consider how wei...| computers are bad
We've talked before about carphones, and certainly one of the only ways to make phones even more interesting is to put them in modes of transportation. Installing telephones in cars made a lot of sense when radiotelephones were big and required a lot of power; and they faded away as cellphones became small enough to have a carphone even outside of your car. There is one mode of transportation where the personal cellphone is pretty useless, though: air travel. Most readers are probably well aw...| computers are bad
I have been slowly working on a book. Don't get too excited, it is on a very niche topic and I will probably eventually barely finish it and then post it here. But in the mean time, I will recount some stories which are related, but don't quite fit in. Today, we'll learn a bit about the self-illumination industry. At the turn of the 20th century, it was discovered that the newfangled element radium could be combined with a phosphor to create a paint that glowed. This was pretty much as cool a...| computers are bad
September 6th, 1996. Eddie Murray, of the Baltimore Orioles, is at bat. He has had 20 home runs in the season; 499 in his career. Anticipation for the 500th had been building for the last week. It would make Murray only the third player to reach 500 home runs and 3000 hits. His career RBI would land in the top ten hitters in the history of the sport; his 500th home run was a statistical inevitability. Less foreseeable was the ball's glancing path through one of the most famous stories of the ...| computers are bad
Recently, I covered some of the history of Ethernet's tenuous relationship with installed telephone cabling. That article focused on the earlier and more business-oriented products, but many of you probably know that there have been a number of efforts to install IP networking over installed telephone wiring in a residential and SOHO environment. There is a broader category of "computer networking over things you already have in your house," and some products remain pretty popular today, alth...| computers are bad
I've seen them at least twice on /r/whatisthisthing, a good couple dozen times on the road, and these days, even in press photos: GMC trucks with custom square boxes on the back, painted dark blue, with US Government "E" plates. These courier escorts, "unmarked" but about as subtle as a Crown Vic with a bull bar, are perhaps the most conspicuous part of an obscure office of a secretive agency. One that seems chronically underfunded but carries out a remarkable task: shipping nuclear weapons. ...| computers are bad
There were thousands of reports: strange aircraft, floating through the sky. A retrospective sum of press accounts finds that some 100,000 people were reported to have witnessed aerial intruders. Despite the scant details associated with most reports, an eager press repeated the claims with fervor. The claims became more fantastical. Prominent people claimed secret knowledge of the origins of the crafts. This was 1896. The airship had just barely been invented, and already the public was seei...| computers are bad
Histories of radio broadcasting often make a particular focus on the most powerful stations. For historic reasons, WBCT of Grand Rapids, Michigan broadcasts FM at 320¸000 watts. Many AM stations are licensed to operate at 50,000 watts, but this modern license limit represented a downgrade for some. WLW, of Cincinnati, once made 500,000. Less is made of the fun you can have under 10 watts: what we now call the Traveler's Information Station (TIS). The TIS was not formally established as a rad...| computers are bad
At the very core of telephone history, there is the telephone operator. For a lot of people, the vague understanding that an operator used to be involved is the main thing they know about historic telephony. Of course, telephone historians, as a group, tend to be much more inclined towards machinery than people. This shows: websites with information on, say, TD-2, seldom tell you much about the operators as people. Fortunately, telephone operators have merited more than just a bit of discussi...| computers are bad
