Ryobi once offered a clever fix to many issues, but time has proven to be the death of a few of them. As tools age, we find better, easier ways to use them, and problems of the past tend to disappear even more quickly than their solutions did. Ryobi was fixing niche problems while it was fixing garage problems, but that time has ended. Today, you may have something in your pocket or garage that caused the end of a tool line. Luckily, this only meant that problems disappeared, since their solutions are gone too.

When you use Linux, there are two dominant and well-established desktop environments that reign supreme: KDE and GNOME. I prefer GNOME, but there's one KDE feature so good that I've found a way not to do without.

I was looking for smart home devices online when I stumbled across a smart knob and immediately wanted to buy it. Then I noticed that exactly what I needed was staring me in the face. My mini hi-fi system on my desk has a large knob that feels gorgeous to turn, so I wondered if I could turn it into a smart home controller.

Spreadsheet formulas used to feel fragile. One wrong column number could throw off an entire report. But when I finally replaced VLOOKUP with XLOOKUP, Excel started feeling predictable, flexible, and surprisingly hard to break.

Many "dead" electronics aren't actually dead. Cracked joints, loose wires, and worn-out connectors are extremely common problems, and they're all easily fixable if you have a decent soldering iron. Over a few years, the small repairs you can make with a soldering iron will save you money and reduce the amount of waste going to the landfill.

There's nothing quite like going to the movies, but a good projector can bridge the gap, giving you a small taste of the theater experience at home.

The headlines called it spyware, security researchers threw warnings around like confetti, and actual WIndows users seemed very unhappy with the idea that their desktop would be screenshotted and saved every few seconds.

I have subscription fatigue, and if you're like most people, you probably do too. It feels like every useful AI feature now comes with a price tag attached to it, and those costs add up fast. I've paid for more than a few AI platforms, but I'm much less likely to do that now.

Getting into a new hobby can be daunting. Enthusiasts brag about spending thousands on fancy bits of equipment, while you’re still trying to figure out if you’re going to stick with it long-term.

There's no shame in admitting that your PC's downloads folder is in disarray. Mine was, and it had been for years. The last time it was in a state you could call orderly was right after I installed Windows 11 on my desktop PC.
