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

Start a new project with grunt & github for (total) dummies…

This short article will guide you through very basics of web development automatization. You’ll need a terminal and some basic knowledge how to use it. I work on Linux bash but it can be basically anything (well maybe not AmigaDOS). I’ll cover git basics also.

Differences between character counting in PHP and Javascript

I’ve recently codded my own validation rules for forms. I’m checking length of a string on a client side and also on a server side (obviously it’s a good practice). After my script went on a production, users started to complain about validation errors (even if data in a form was passed proper). This is really strange but…
