Putting a smart watch or band on your wrist means installing an app on your phone. That makes sense, given the tiny screens on these devices. The problem is that these apps tend to do more than you’d expect. Huawei’s, for example, has a store for watch faces and AI-powered coaching and who knows what else it does...
A screensaver that displays, in giant numbers, the temperature and/or the hour against a black background. There are 30 fonts to choose from, many combinations, and an option that moves the pixels a little bit once in a while to avoid to “burn” OLED screens. Free, for macOS and Windows.
Add it to the list of trivial things macOS inexplicably can’t do: turn off the laptop display when it connects to an external monitor. Until yesterday, what I did was use a utility — MonitorControl — to reduce the built-in display brightness to the minimum. It’s effectively off, but still active, meaning the mouse...

This year, unlike 2025, I updated my computer as soon as macOS 27 Golden Gate was released. The positive feedback during the testing period was encouraging, and deep down I figured that the original Liquid Glass, from macOS 26 Tahoe, was so bad that it couldn’t get any worse. No surprise: macOS 27 looks better....
This Wednesday (16th), the stable version of Gnome 51, the famous desktop environment for Linux, was released. (Announcement video.) The highlight is improvements in performance and graphics. I don’t know if it was already there, but I’m glad to see that Sushi is a default app and was ported to GTK4. It displays...
Browse and organize your physical media collection on this website. The standout feature is the display: a three-dimensional shelf. “Take down” (click on) a movie and examine the box from every angle. For free.
I’ve published more than a couple of pieces on this blog trying to raise awareness about the risks of viral photo-editing apps, like FaceApp back in 2019 [pt_BR]. We are curious beings. The promise of looking into a magic mirror that shows us old, as a different gender, or in another era is nearly irresistible — a...
