HowTo Geek ☛ How I turn my Linux terminal sessions into beautiful, compact GIFs
Have you ever seen those GIFs that animate the command line and wondered how they look so good? Or seen a tiny GIF and wondered how they're so small? It's not as difficult as you may think, and I address both with two easy-to-use commands.
VHS is a command to generate GIFs from a script file, and Gifsicle is a command to edit them. When used together, they can make highly compact and professional-looking GIFs. I cover what VHS is, how to use it, and how to compress the resulting GIF so that it's barely larger than a typical PNG file.

HowTo Geek ☛ 7 virtual machine mistakes I made so you don’t have to
Almost all virtualization programs include guest additions—including VirtualBox. With guest additions, your virtualization host (so VirtualBox) will be able to better communicate with the virtualized operating system.
These days, I use Proxmox for my virtualization, and installing guest additions for Proxmox allows me to see the IP address of the virtualized guest as well as have better communication from my host to the virtual machine. VirtualBox’s guest additions work in a very similar way, allowing your host (VirtualBox) to access parts of the guest (the virtual machine) that it otherwise couldn't access.
