What are keyboard o rings? Do keyboard o rings work? I’ve installed them on my mechanical keyboards and I’m happy with them. Here’s why.

Removing black marks from linoleum floors
I like linoleum floors because they’re pretty resilient and easy to take care of. But they can get a bit marked up in some cases. Here’s how to remove black marks from linoleum floors and, more importantly, how to keep them from coming back.
Black marks on linoleum floors are usually a result of the feet on tables or chairs rubbing against the floor while you scoot it. They’ll come off with a mild abrasive and moderate scrubbing.
Windows 10 mouse cursor disappears? Try this.
If your Windows 10 mouse cursor disappears, you’re not alone. It happens to me too. It’s a bit maddening but not super hard to fix.
Lionel HO scale
Every 15-20 years or so, Lionel ventures into HO scale again. Lionel is generally associated with bigger trains. But the HO scale market is so large, Lionel wants part of it. HO scale trains are, in terms of both scale and gauge, the smallest trains Lionel makes.
ESS Audiodrive: An underrated retro sound card
Recently I’ve heard a few people singing the virtues of the ESS Audiodrive, a budget sound card from the 1990s. It turns out that in several regards, especially if you want to run older software, the ESS Audiodrive is a better Sound Blaster than the Sound Blaster 16.
The ESS Audiodrive is a 16-bit ISA sound card that can emulate older Sound Blasters. Some late 90s software supports it natively, but older DOS games use it as a Sound Blaster, Sound Blaster Pro, or Ad Lib.
Inspector fails outlets not wrapped in tape
Why would an inspector fail an outlet not wrapped in tape? It sounds overly picky, but there are some reasons why taping your outlets is a good idea, at least. And I can think of one case where it’s required.
My rebuilt IBM 5170 PC/AT
I have what appears to be an IBM 5170 in my collection. I’ve owned it since the mid 1990s. There’s not much original about it. Part of that is due to the ravages of time. But it’s mine. And since I did some fairly major repairs to it myself, I’m pretty attached to my Frankenstein PC/AT.
It’s a Frankenstein because it has parts from at least six different computers in it.
Why we have a cybersecurity talent shortage
We have a cybersecurity talent shortage. You know it, and I know it. But part of the problem is self-inflicted. We don’t know how to interview.
A common complaint about security professionals is that we’re all smug know-it-alls. We have that reputation because that’s precisely the kind of person our interview process is designed to find. We won’t solve the cybersecurity talent shortage and our people skills problem until we get beyond looking for people who can pass CISSP in a suit.
Repair the fiberboard insulator in a train motor
The fiberboard insulators in prewar electric train motors can break or warp over time. If that happens, you have options besides plundering one from another motor. Here’s how to replace or repair the fiberboard insulator in a train motor.
What is fuzzing?
What is fuzzing? Fuzz testing, or fuzzing, is a concept in computer security. Like the name suggests, it’s the practice of sending messed-up data to a system to see how it behaves. A good computer system should handle fuzzing gracefully. As you might guess, not all do.
When a computer receives data it doesn’t expect, it may malfunction in unpredictable ways. Fuzzing attempts to find those malfunctions.
