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?
