David L. Farquhar on technology old and new, computer security, and more
Today we take buying online for granted. You pull up a web site, find what you want, and in a couple of clicks, you put it in your virtual cart and pay for it. It’s fast and convenient. It was very different in the 80s and 90s. Better? Maybe. Maybe not. But definitely different.
What is the difference between CVE and CVSS? It can be confusing, especially if you’re not a security professional. Here’s how to make sense of the alphabet soup you hear from security analysts like me.
Both CVE and CVSS are industry standards that refer to vulnerabilities in computer software. Think of CVSS as the tracking number, and CVE as a measure of severity.
The TRS-80 MC-10 Micro Color Computer was a really cheap beginner’s home computer from 1983, designed to compete with cheap computers from Timex. It was a little bit too limited and perhaps not quite cheap enough, so it only lasted a year on the market. But it has a devoted following today.
Initially priced at $119 and eventually discounted to as little as $49.95, the TRS-80 MC-10 Micro Color Computer was Radio Shack’s entry-level computer in 1983 and 1984. Like much of the computer industry, Tandy overestimated the demand for cheap, limited computers and the MC-10 flopped.
The 1983 video game crash is something most retro gaming enthusiasts are familiar with. But it didn’t necessarily happen exactly the way people remember it today. To Atari, it certainly felt like a crash. But to its consumers, it was much less sudden than that.
The video game crash was a swift and dramatic loss of interest in video game consoles, as consumer mindshare shifted to home computers. But it wasn’t an overnight event.
Can you put a x16 GPU in a PCIe x1 slot, and will it work? It depends. There are several reasons you may want to do this, but you may run into some issues.
A x16 GPU functions just fine in a PCIe x1 slot. However, in most motherboards it doesn’t fit unless you modify the card or the slot.
VLOOKUP is a very useful tool in Excel but can be difficult to get right. Here’s how to use Excel VLOOKUP, including an example and what to do when it doesn’t work right.
VLOOKUP is a useful tool for data analysis in Excel, especially merging data from multiple sources. It’s a frequent question in job interviews for business analysts and other jobs that handle data.
What In Information Security and Information Technology, CVE stands for Common Vulnerabilities and Exposure. It is a standard identifier for tracking vulnerabilities in computer software. I’ve only deployed updates to fix about 800,000 of them, but that experience taught me a little bit about working with them.
The CVE database is maintained by MITRE, and there are about 100 CVE Numbering Authorities (CNAs) who assign them. The CVEs themselves don’t include a lot of detail, but they serve the purpose of providing a common identifier that vendors and security professionals can use to track each unique security flaw.
Some Youtubers, including Casual Retro Gamer, use picture ledges to keep their vintage computer systems on the wall when they’re not using them. You can buy a picture ledge, but they’re easy to make, too. And if you make them, you can make them whatever length you want.
A picture ledge is a small, J-shaped shelf that mounts on the wall, normally used for displaying art without having to use a bunch of hangers. But their size works well for vintage home computers and game consoles too, allowing you to store and display them.
My power flickered and my computer restarted. Everything seemed OK, but then I noticed my audio wasn’t working. If your experience Windows 10 audio not working suddenly, especially when you haven’t changed anything, here are some things to try.
Sure, the problem could be a driver, or your volume knob, or a cable problem. But if your audio stopped working suddenly, it’s more likely that Windows just decided to change outputs on you, and that takes about 10 seconds to fix.
As a retro computer hobbyist, former bookseller, and landlord, I’ve had to deal with stickers a lot. It’s not always easy, but it’s possible to remove sticker residue from almost anything. Even paper. Yes, even paper. I’ve removed stickers from inside books and left the page completely undamaged. Here’s how.
Removing sticker residue often requires use of several different techniques including heat and chemicals. My favorite is rubber cement thinner, as it will even remove sticker residue from paper, but different surfaces require different options.
