David L. Farquhar on technology old and new, computer security, and more
Where to sell computer parts can be a difficult question. I remember a time when cities like St. Louis had tons of used computer stores more than happy to sell your parts on consignment. Those days are over. But there is still a market for used computer parts, and the Internet provides a couple of venues to pick up the slack.
Whether you just want to raise money for your next purchase or try your hand as a professional reseller, you have some options.
How much is my computer worth? That’s a really common question after you buy a new computer. Or when you find your old computer in the basement. Here’s how to find out what your computer is worth.
If your computer is more than a few years old, there’s a reasonable chance someone will be interested in it as a collectible. And if your computer isn’t old enough to be vintage but it’s new enough to be usable, there’s a market for usable secondhand computers too. A blog post I wrote on finding vintage computers gets steady traffic, so I know there are plenty of people looking for old computers. Here’s how to find out if they want yours.
What is satin finish? Satin can be a very versatile finish for renovating a home, whether you’re talking paint, polyurethane, or hardwood floors. It has some disadvantages but also has notable advantages in most cases. Let’s take a look at what satin finish has to offer.
And sometimes when people talk about satin finish, they’re talking about the screens on mobile devices or computer monitors. I’ll cover that too.
Over the course of its 12 years on the market, Commodore released a number of Commodore 64 models. The computer’s capability changed very little over time, but the technology did. The world changed a lot between 1982 and 1994, and that gave Commodore some opportunities to lower costs, chase other market segments, or both. The Commodore SX64, also known as the Executive 64, was an example of this, trying to get into the luggable market where Compaq thrived. It was a pioneering machine but didn’t set any sales records.
What does compressing a file do? There are several ways to describe it, from eliminating redundancy, to just thinking of it as digital shorthand. The goal is to make the file take up less space on disk and in transit. How it works is a bit more complicated.
If you feel like you replace your modem more often than you replace your computer, you’re probably not imagining things. And if your relative’s or neighbor’s modem lasts longer than yours, you may not be imagining things either. So how long do modems last? And what can you do about it?
If your ISP provides your modem, it’s not your problem when it fails. Except for the wait to replace it, I suppose. But you won’t be out any money. But if you have to provide the modem, the cost and life expectancy does matter.
Why is collaboration important? I once worked someplace that had collaboration as a core value, but not all of its employees collaborated. So I learned first hand why collaboration is important. It’s one of the best ways to be successful without making enemies.
I’m a security professional by trade. Security professionals are notoriously bad at collaborating. Collaboration may be the only thing I do better than other security professionals I’ve met, so I see the importance of it. And not just in security, and not just in IT.
Figuring out the best time to buy computer parts is tricky. It’s not quite like saying the best time to buy a TV is right around the Super Bowl. But there are some tips you can follow to help you find the best deals.
Good timing won’t make building a PC cheaper than buying one, but it can at least narrow the gap, if you have the patience to buy when you find a deal rather than buying all your parts in one shot.
What is a Zip drive? It’s a relic of late 1990s computing, rendered obsolete by USB flash drives, and anyone who remembers them will say good riddance. Not that I have strong opinions about it. But even though I don’t remember Iomega Zip drives fondly, they served a real, legitimate purpose in the 1990s. Like them or not, we needed them.
I’m not alone in this. In 2006, PC World ranked the Iomega Zip drive as the 15th worst technology product of all time. The next year, it ranked it the 23rd best technology product of all time. How can it be so good and so bad at the same time? We needed it really badly, but it didn’t work well.
An important financial decision we all make, especially when it comes to cars, is lease vs own. I received some poor advice on this when I was young. Since I don’t want people to repeat the same mistakes I made, let’s go over the two options and what makes more sense.
