Composite vs S-Video

Vintage computers and video game systems, as well as other consumer devices, often offer more than one video output option. Composite and S-Video are two of the most common options. Let’s look at composite vs S-Video, and why one is better than the other.

Resize images in bulk in Windows 10

In case you haven’t noticed, I blog a lot. And I learned the hard way that if my blog posts don’t have pictures, no one ever clicks on them. Since I have a day job, I tend to write in bulk, and that means I tend to deal with images in bulk. Here’s how I resize images in bulk in Windows 10.

The classic application Irfanview, a favorite image viewer among long-time Windows users, includes a bulk rename feature. Here’s where it hides and how to use it.

Dave Farquhar Hardware

In early August 2020, strong storms blew through St. Louis, causing power outages and other disruptions. A friend shared a story about the storm causing a modem to burst into flames spectacularly, then asked if it was real. It probably was.

Was the Macintosh a failure?

Was the Macintosh a failure? I’d call it a late bloomer more than I’d call it a failure. But in the mid 1980s, industry analysts were calling it a failure. Here’s why, and how it survived.

Analysts in the mid 1980s considered the Macintosh a failure because its sales were disappointing. It took the platform several years to come into its own, and of course, no one would call it a failure today. It was the machine that was supposed to usher in the future, and it took a while for that future to arrive.

How to change Windows 10’s default image viewer

Windows 10 is greedy about some of its file associations. My favorite JPEG viewer is Irfanview, but Windows 10 doesn’t make it easy to use it by default. Here’s how to change Windows 10’s default JPEG viewer to something lighter-weight than the default Photos app. I like Irfanview because it’s lightweight and surprisingly powerful, but this trick works for other apps too. Here’s how to change Windows 10’s default image viewer.

With very few exceptions, only applications installed from the Microsoft store are eligible to be set as the default viewer for image files. To set your default picture viewer to something like Irfanview, you have to install it from the store first to make it eligible.
