Amazon took some people aback when they said Honey, a company recently bought by Paypal, was a security risk. That raised some questions. Is the Honey Chrome extension safe? Is Honey a security issue? Let’s dig into it.
While it may be difficult or impossible to pinpoint any specific security issue in Honey, that doesn’t necessarily give it the green light. Regardless of how secure it may be, Honey definitely has privacy concerns, and that’s why security experts have concern about it.
If you’d asked the question a couple of decades ago, the answer probably would have been no. But thanks to advances in paint, these days you can paint vinyl siding. Not only that, there sometimes are compelling reasons to do so.
The point of vinyl siding was for it to be maintenance free over the course of its life. But vinyl siding has a usable life of 25-30 years, so if your vinyl siding is reaching that point, painting it is a way to extend that usable life.
What was the most popular Commodore 64 monitor? What’s the best one today? Those aren’t quite as straightforward questions as they might seem. While there are a small number of clear-cut favorites, the truth is there were lots of different monitors C-64 users used in the 80s. And there are lots of options today too.
The “proper,” period-correct monitor for a Commodore 64 is the brown 1701 or 1702 for the breadbin-style C-64, or the beige 1802 for the streamlined C-64C. But there were lots of other third-party monitors, and many people used television sets.
Super glue is permanent, right? Actually it’s not, and it’s not necessarily as strong as we think it is either. In some cases, super glue is extremely strong and worthy of its name. But sometimes it’s a pushover, and that can be a good thing. That means you can get rid of it when you need to. Here’s how to remove super glue.
Super glue dissolves readily in acetone, or you can use specialty debonders sold in hobby shops, or use a couple of my other tricks to break its bond. Water will not help, as moisture accelerates its bond.
In metallurgy, zinc pest is a problem that occurs when impurities are introduced in the process of diecasting. The problem causes the metal to crack and disintegrate, in extreme cases crumbling to dust. It mostly affects products made in the 1920s-1950s.
Zinc pest or zinc rot was discovered in 1923 and well understood by the 1930s. It is relatively uncommon today, but can still occur due to sloppy manufacturing processes.
I had an old Formica backsplash, original to my house. It was still in good condition, but I’m not sure it looked good in 1965, let alone now. I wanted to replace it with tile but didn’t relish the $700 expense. What if I could lay tile right over Formica or other laminates? Here’s how to tile over Formica backsplash.
Tile mastic doesn’t stick well to Formica and other laminates, and the manufacturers won’t warranty it if you try. The most cost-effective solution in terms of time and money is a peel-and-stick product. As long as your existing backsplash is in good condition, it’s a good candidate for this.
WD-40 has a number of uses around the house. It’s been a longtime tinkerer’s favorite for a reason. But it may also be one of the most frequently misused household chemicals. So here’s what WD-40 is used for, and best not used for.
WD-40’s main uses are protecting metals from water, as a penetrating oil to loosen stuck parts, and even as a cleaner. It is not, however, a very effective general purpose lubricant.
I thought the debate ended when the file format went obsolete, but then GIF came back as an animated file format. And with it came the argument of how to pronounce GIF. Is it JIF or GIF?
Steve Wilhite, the inventor of the file format, pronounced it JIF, and in the 80s, so did just about everyone else. In the mid 90s, pronouncing it like GIFT without the “T” became common, the logic being that the “G” stands for “Graphics,” not “Jraphics.”
If you’re hanging something heavy like a cabinet or a shelf and want it to stay on the wall, you need to attach it to a wall stud. Otherwise it’s liable to pull out, damaging your drywall in the process, and possibly causing other damage too. So here’s how to find a stud in the wall.
The most common method is to use a tool, which costs around $20. But even without a tool, with a little practice you can use visual or audio clues to find a stud in the wall.
The Liberty Falls Collection was a collectible holiday village popular in the 1990s. The product was produced in China and sold in the United States in large department stores. It was on the market from 1991 to 2008.
The Liberty Falls Collection is a bit obscure today, but it isn’t especially rare. Purchasers frequently packed the items away in the original boxes every year, so when they turn up, they often turn up in like-new condition.
