David L. Farquhar on technology old and new, computer security, and more
I picked up a Dell Optiplex 3010 for cheap cheap over the weekend. It was a nice computer for its day, especially in the right configuration. But its day was a long time ago at this point. That said, it definitely has upgrade potential to get more life out of it.
The Optiplex 3010 is still fast enough to be serviceable, and can take an SSD, a video card upgrade, and up to 16 GB of RAM. This configuration will run Windows 10 well and even works surprisingly well for midrange gaming.
Is Windows 7 safe to use? No. Next question? Alright, I guess I need to explain why, without being so dismissive.
Support for Windows 7 ended in January 2020, which means there have been no new security updates for Windows since. That means Windows 7 isn’t safe to use, even with a firewall and antivirus.
Somehow I escaped doing helpdesk or phone support early in my career. But I didn’t escape selling computers at retail at Best Buy. And since this was the 90s, I have some good stories. Some of them happened to me. Some happened to coworkers. None of them should be true.
Depending on the look you’re after, dust can detract from your model railroad layout’s appearance. Dust especially shows up in photographs. Here’s how to dust your model railroad quickly and easily.
A former classmate told me his employer is making him take Kevin Mitnick’s security awareness training course. “Is he really the world’s most famous hacker?” he asked me. “And if he is, why should I trust a word he says?”
Those are excellent questions. I happen to have reviewed all of Kevin Mitnick’s various courses for a previous employer, so I’m familiar with them. And I had to take Kevin Mitnick Security Awareness Training this year myself. I don’t agree with the life decisions Kevin Mitnick made that landed him in prison, of course. But overall, I had only very minor objections to his training. Here’s why.
Thanks to an influx of volunteers donating computer power to support COVID-19 research, the Folding@home project is now, in effect, the world’s most powerful supercomputer. But how much computer power is necessary to make a difference? After comparing notes with a couple of others, I think I have some answers.
After the hugely popular Windows 7, Microsoft followed up with the terrible Windows 8, and the only slightly less terrible Windows 8.1. And then they came out with Windows 10, which, while not as beloved as Windows 7, certainly was better than 8. But they skipped 9. Why no Windows 9?
Believe it or not, the reason Microsoft skipped Windows 9 has nothing to do with Windows 7 or Windows 8. The reason is a decades-old shortcut that was beyond Microsoft’s control.
I installed the Folding@home client on every computer in the house with something newer than a Pentium 4 in it. But GPU power is much better than CPU power. Even my lowly Nvidia Geforce 210. Here’s how I fixed an opencl.dll not found error, though I never was able to get much use from Foldingathome with the Nvidia Geforce 210.
Both Nvidia drivers and the Foldingathome client are finicky. When in doubt, uninstalling and reinstalling can work wonders. But while I was able to get the client to recognize my Geforce 210, I was never able to get it to fold.
Being laid off isn’t something that happens to everyone. But it happens to more than you would think. It’s about being in the wrong place at the wrong time. That’s the key. Remember it’s not a failing on you. Here’s what to do if you’ve been laid off.
The keys to surviving a layoff is to burn as few bridges as possible, use the resources available to you, and try to land on your feet somewhere else. Here are some tips for doing that.
Charter Communications is the second largest cable operator in the United States. The history of Charter Communications includes early financial struggles before emerging in recent years as the second largest company of its kind. Here’s a look back at its history.
