Have you ever wondered if it's safe to use your electronic device in another country without a travel adapter? The answer is most likely on the adapter itself.
Most AC adapters (the little boxes you plug into the wall) have tiny print on them that explains the supported voltage.

People often think of adjustable desks as "sit/stand" desks, which you can use while sitting or standing. Apparently, some people can work while standing, but I tried it once, and I only lasted a few minutes.

In September of 2014 (yes, over 10 years ago ?), I published a tip titled Check Your Sources. I reminded PC.net users to verify their online information sources and ensure they were credible. That advice is even more relevant today.
When we ask AI platforms like ChatGPT or Google Gemini a question, it's easy to accept their answers as truth. Usually, the answers are accurate. But not always.

It has come to my attention that a lot of people don't use the Notes app on their smartphone. That's too bad because, IMO, it's one of the most useful apps on your phone. I don't use it to "take notes," but it's my go-to app for jotting down quick things that I don't want to forget.
Examples of notes that I've created and use regularly:
