How to unfreeze KDE’s plasmashell?

I’m using Debian 9.4 and this freaking KDE5 is freezing very often! What you can do when your desktop stops responding? Restart computer? Use ALT+CTRL+F1…12? Nah! There’s a better solution!

Simply edit your  ~/.bash_aliases:

nano ~/.bash_aliases

And append to it:

alias restart-plasma='kquitapp5 plasmashell && kstart plasmashell'

Now whenever your plasma desktop starts trolling you, go to your console and type restart-plasma voilàDezombified!

PS. Use tilda to open console in every shitty situation you’ll get into! Simply press F12 and you’ll get nice Quake like terminal.

Quick optimization of jpeg files in a directory (Linux bash)

Firstly install jpegoptim.

You can do this on Debian like systems using apt:

sudo apt-get update && sudo apt-get install jpegoptim

Then go to directory with jpeg files and use this command:

find . -name '*.jpg' -exec jpegoptim -m70 -o -f --strip-all {} \;

It will find all jpg files recursively and optimize with following settings:

  • m70 stands for jpeg quality (about 70 – 80 should be fine but lossy)
  • o is for overwrite
  • f is for force
  • strip-all removes all EXIF and other textual data from files
