Plug falls out of outlet? Here’s how to fix it

If a plug falls out of an outlet after you plug it in, that’s not how it’s supposed to work. A plug is supposed to fit firmly in an outlet so that it doesn’t fall out on its own. You shouldn’t have to exert very much force to remove it, but you are supposed to need to exert a small amount. If your plug falls out of an outlet, here’s how to fix it.

SCCM vs WSUS

Since I work for a vulnerability management company, I get tons and tons of questions about patch management. I don’t speak for my employer, and they probably don’t have an opinion since neither product comes close to meeting their needs. But I’m glad to share what I know. Recently, someone asked me which is better, SCCM or WSUS. My answer probably was not what they were expecting me to say.

Intel 80186 CPU: So misunderstood

Intel 80186 CPU: So misunderstood

Back when a 386 or 486 PC was hot stuff, I remember a common insult for a slow PC being, “What is that thing, a 186?” But no one we knew had a 186 PC, and no one really knew why either. In this blog, post, we will explore the Intel 80186, the CPU the PC industry forgot, why a misconception exists that it was a failure, and how both things can be true at the same time.

Although the 80186 powered two infamous PC-compatible flops in the early 1980s, a company founded by two Californians in a garage did use a 186-compatible CPU in a pioneering handheld computer about a decade later. Additionally, the 186 saw use in other embedded applications.

Marx Happi-Time 9640 train set

Marx train set 9640 was an electric train set Marx that Sears sold in 1952. You may also hear collectors refer to it as Happi-Time train set 9640, because that’s what Marx printed on the box. It featured Marx’s best locomotive pulling 3/16 scale metal cars. This set marked the farewell for that locomotive, as Marx bundled the set to use up remaining discontinued inventory, to clear the way for its 1953 product refresh.

What happened to Adaptec?

For about 20 years, Adaptec was synonymous with SCSI controllers for PCs. Their controllers were frequently imitated, and its competitors undercut them in price. But the reliability, performance, and compatibility of Adaptec products was tough to beat. So if you wanted the very best, you bought Adaptec. In this blog post, I’ll uncover what happened to Adaptec. Hint: they didn’t go out of business.

Reduce the pinginess of a mechanical keyboard

Reduce the pinginess of a mechanical keyboard

A mechanical keyboard will always be louder than a membrane keyboard because of their physical characteristics. A membrane keyboard involves a plastic tray with some keyboard sliders striking a rubber membrane to make contact with a circuit board. Mechanical keyboards almost always have a metal plate that holds mechanical switches with springs in them, so even a linear switch that doesn’t click still makes a tapping noise when it bottoms out, and when bottoming out, it can make that metal plate vibrate and make a pinging noise. Here’s how I reduced the pinginess of my mechanical keyboard.
