Using Barrier to control multiple computers regardless of operating system

I don't often use multiple monitors at once, but when I do, I'm using multiple computers too. I'm mainly doing this to test websites on multiple operating systems as my desktop machine runs Linux Mint and my work laptop has Windows 10 on it. Of course I could use Virtualbox to run any number of operating systems, but having a separate device makes things a bit more simple for me. What I despise is using the laptop keyboard and the trackpad. Wouldn't it be nice if I could use the desktop keyboard and mouse on the laptop too?

Revive an old laptop with Chrome OS

If you have been using computers for a few decades, there is a good chance that you too have a few old desktop and laptop computers collecting dust in your house. They are too old to use and have little value, so selling them is not a worthwile endevour. You can't even give them to family members as even they find them lacking in power. Have you tried to use a 10 year old laptop with Windows 10? Not fun... Wouldn't it be nice if you could magically make the old hardware more powerful?

Prettify Ubuntu 20.04

The Unity desktop was quite a big step forward in usability and design back when it came out (at least in my opinion), but by the end of the decade, the reskinned Gnome 3 environment became quite dated compared to the competitors. There are things in both macOS (window decorations) and Windows 10 that I like way more, but I also want to keep Ubuntu for the speed and stability.

Using your Android phone as a webcam for Ubuntu 20.04 with DroidCam

During the current pandemic, the home office suddenly became the preferred mode of work. This, of course, caused a huge increase in webcam prices and shortages in supply. I ran into the same problem and my laptop camera was no viable alternative either with its subpar quality. Luckily, there is a way to use my better-than-average phone camera for conference calls with the desktop computer running Ubuntu.
