Hidden files from file managers, thumbnail creation and applications can be very annoying, especially because they stay forever. In most ".gitignore" files at least the ".DS_Store" (MacOS finder) is listed, but what about all the other hidden Linux application files?

The AMD Ryzen ThreadRipper CPU is, thanks to the enormous core count, perfect for virtualization. By passing an graphic card to the VM it's possible achieve almost bare metal GPU performance, which is important for gaming or the use of graphical intensive software (like Adobe Photoshop).

In the past BIOS updates often required Windows or booting from a stick. Thankfully with the Lenovo ThinkPad P1 and the almost identical ThinkPad X1 Extreme, you can update the BIOS directly from Linux.

In Sway, the wayland version of i3-gaps, regular x11 screenshot tools, like maim are not working. Thankfully there are some alternatives to consider.

Sometimes it’s useful to backup only files in an folder (and subfolders) that have been changed in the last 7 days.

For this you can use find and tar:

find . -mtime -7 -print | xargs tar cvzf "backup-$(date +%y-%m-%d).tar.gz"

If you only want to backup certain file types you can extend the fin...

If you navigate a lot on the terminal there are some little helpers that can make your life easier. One particular unknown is the d command in the zsh.
