Stop cordless phone interference

Cordless phone interference has always been a problem–phones interfering with other things, and other things interfering with them.

That was the draw of 900 MHz phones. There wasn’t anything else running on that frequency at the time, so there was little to no interference. But 900 MHz didn’t sound hi-tech in the age of gigahertz computers. So in the early 2000s, 900 MHz gave way to 2.4 GHz and 5 GHz phones. That brought back the problem, because there’s so much other stuff operating at those frequencies these days, like wireless computer networks. But there is a solution that doesn’t involve digging up a 20-year-old 900 MHz phone and trying to find a battery that works in it.

Chrome says the file may have been moved or deleted

When opening locally stored PDFs in Chrome, sometimes Chrome says the file may have been moved or deleted. More specifically, the error message says “Your file was not found. It may have been moved or deleted. ERR_FILE_NOT_FOUND.” But nobody moved or deleted the file, because I just clicked on it. In fact, I could still see it sitting right there in Windows Explorer.

Oddly enough, I had other files in the very same folder that opened fine. No errors.

My Toyota says key battery low

I got a scary message from my 2011 Toyota Camry. “Key battery low,” the message on the dashboard read. You can read that two ways. “Key” could mean they keyfob that unlocks and starts the car. Or “key” could mean “critical.” Fortunately, when a Toyota says key battery low, it means the key that unlocks and starts the car.

You can fix this yourself and you don’t have to find a Toyota dealer.

Common AmigaDOS commands

The Amiga had a command line, or CLI. It was a rather powerful CLI, especially for its time. But there are a number of differences between AmigaDOS and other operating systems you may be familiar with. These are the common AmigaDOS commands and their equivalents from other operating systems like DOS, Windows, Unix or Linux.

I’ve never seen a primer that relates or cross-references Amiga commands to Windows and Unix. So I wrote one. I hope it helps you understand your Amiga better. Because Amiga is sometimes like Windows and sometimes it’s like Unix, I think it might. And maybe, just maybe, you’ll learn something you didn’t know about Windows or Unix too.

How to value baseball cards

If you have a collection, knowing how to value baseball cards is helpful. That way, if you need to insure or liquidate the collection, you’ll receive a fair price.

But fair also means realistic. A lot of factors go into value. It’s not too different from valuing other vintage collectibles, so if you already know about those, you have a head start.

Also, even though my focus here is on baseball cards, more or less the same principles hold true for any vintage trading cards: football, basketball, hockey, or non-sports cards.
