David L. Farquhar on technology old and new, computer security, and more
It happens on all old computers, and even some not-so-old computers. The rubber pads that sit on the bottom of Commodore 64s to protect the desk surface and keep it from sliding around can fall off, liquify, or otherwise go missing. But even though the last ever C-64 was built sometime in early 1994, you can still get Commodore 64 replacement rubber feet. Here’s how.
My friend does vulnerability management for a company that likes to rebuild machines instead of patching them. I don’t judge; that’s how I wanted to patch machines when I was a sysadmin but I didn’t have fast enough storage. But if you do this, you’re liable to end up with duplicate machines in your reports. One unpatched, and the other one (hopefully) patched. Here’s how to rebuild machines without making duplicates in Qualys or Tenable.
I wanted a mouse for my IBM 5170 and my 386DX-33 systems, but both of them need a serial mouse. I mean old school RS-232 serial, not USB. Finding a serial optical mouse isn’t easy. Plus I wanted something that would look the part. I got an early 90s Microsoft mouse that matches the end of the 286/386 era, and a Logitech C7, but both worked badly. So I had to learn again how to refurbish a vintage ball mouse.
Homonyms are terrible things in the English language. One example is led vs lead. Which one is past tense?

When that happens, you don’t want it to cause a problem. Here’s what happened to me once when I didn’t choose a password carefully.
Viewing message headers is helpful for troubleshooting, and also making sure you’re not getting phished. Microsoft moved things around in recent versions of Outlook, so here’s how to view message headers in Outlook–the current version.
Faraday Electronics was, for a brief period of time, a leading maker of integrated chipsets for XT-class PC clones. But if you’re fixing an old XT clone and need a Faraday chip, they can be hard to come by. Knowing what happened to Faraday Electronics can help you in locating spare parts.
If you work in a corporate environment, there’s a chance you see something called the Qualys Cloud Agent running on your computer. And information about this mysterious agent can be hard to come by? What does the Qualys cloud agent do? How does it work? I’m glad you asked.
The other day my son was working with a Zip file and getting frustrated. He was trying to delete a large number of files from it, and the CPU went to 100% usage and never finished. Here’s how I got him around the problem of high CPU usage with Zip files, or Windows Zip folders being slow.
