The Aero Monorail was a futuristic monorail train first offered in 1932. Manufactured in St. Louis by the eponymously named Aero Monorail Company, it was designed to suspend over Lionel standard gauge track and run faster than the standard gauge train.
The stands came in two varieties: a pair of free standing towers, and a series of towers that slipped under Standard gauge track and used the same 42-inch diameter. The motor looked like an Erector motor and was intended to run on 6-8 volts, either DC or AC.

I once had an electrical outlet with a light switch next to it, in a bathroom. When I replaced the outlet with a GFCI, the light switch quit working.
When you have a GFCI and a light switch is involved, you have to wire things a bit differently so it all works.
Here’s how I fixed it, using a length of wire (use black, or if you only have white wire, put some electrical tape on it) and a wire nut.

How do you compare the Commodore 64 vs VIC-20?
The Commodore 64 and its predecessor, the VIC-20, look a lot alike, and the VIC-20’s design certainly influenced the 64. The 64 is the best selling computer model of all time, and I argue the VIC-20 was the first really successful home computer.
But even though the two machines are closely related, there are significant differences between them. Let’s compare and contrast the two venerable machines.

It’s a common question: Why were early computers beige? In some ways it seems a curious color choice today.
Due to their tendency to yellow with age, there’s some occasional debate over what color early home computers really were. But, having spent about a decade working with them starting with when they were new, I can tell you that the Commodore 64 was definitely a tan or beige color. It’s not terribly far off from a Sherwin-Williams color that they call Keystone Gray, or a Benjamin Moore color they call Bennington Gray. Its official color match is called RAL1019. It’s a dark beige with gray undertones. But the color definitely runs toward tan or brown much more than it runs toward the gray color of, say, an Atari XE or Atari ST computer of the mid-late 1980s.
Early computers from Apple and Atari were similar colors. They weren’t a spot-on match for the color Commodore used, but much closer to that color than to the light beige that became associated with PC clones for a couple of decades before black came into vogue.
I have no insider knowledge but I think I can provide some insight into the design choices.

Changing a worn-out garbage disposal can be a 10-minute job–assuming you anticipate everything, use the same brand as the old one, you know what you’re doing, and the person who installed the old one was at least as competent as you.
It didn’t quite work out for me like that the last time.

Fireeye runs a bunch of its processes as root, a practice that’s been a no-no since the late 1990s, and they’re more interested in litigation than they are in working with the guy who discovered it.
The attitude is all too common.

The ultimate DOS gaming PC is a topic that I’ve seen come up in forums frequently, and that I’ve been asked directly a number of times. I guess since I published advice on running DOS games on Windows PCs on two continents, people figured I knew something about that. I guess I fooled them!
The trouble is that no single PC can really be the “ultimate” DOS game machine. Well, not if your goal is to be able to optimally run everything from early 1980s titles designed for the original IBM PC up to the last DOS version of Quake. I learned that the hard way in 1995 or 1996, even before Quake existed. Continue reading Building DOS gaming PCs
St. Louis-based security researcher Charlie Miller and his collaborator Chris Valasek got themselves in the news this week by hacking a Jeep driven by Wired journalist Andy Greenberg on I-64.
The reaction was mixed, but one common theme was, why I-64, where lives could have been at risk, rather than an abandoned parking lot?
I don’t know Miller or Valasek, so it goes without saying I don’t speak for either one of them, but I think I have a pretty good idea why they did it that way.

An anonymous reader asked why journalists protect their sources.
It’s a fair question but an easy one to answer. Part of a journalist’s role in society is accountability. When something is wrong, the journalist is supposed to raise awareness.
Continue reading Yes, an ethical journalist protects his/her sources
Over the Independence Day weekend, I took my family to the Bonne Terre Mine, about 50 miles south of St. Louis on Highway 67. It was once one of the world’s largest active lead mines, and the area around Bonne Terre is still known as the Lead Belt. Mining is still the major industry in southeast Missouri, and the area is dotted with big piles of mining waste, which the locals refer to as “chat.”
Mining in the area started way back in 1720 by French settlers; Bonne Terre Mine opened in 1860. It closed in 1962.
