In the previous newsletter, I shared a bunch of free Linux books.
In this one, I am sharing free Docker learning resources. After all, Docker is still a desired skill in the industry. And it also helps build self-hosted DIY projects easily.
I hope spending too much time learning Docker doesn't spoil your Valentine's plan 😉
💭 Let's have a look at the interesting things included here:
- Free learning resources for Docker (obviously)
- Selected LHB Linux articles
- Suicide Linux (nothing harmful to you)
- Memes that can only be understood by Linux users
📦 Learn Docker for FREEEE!!
If you are a beginner, I would recommend starting with the essentials. This one requires creating an account with them.
This is why I prefer this one that goes in detail and doesn't require creating account or logging in. It's a video series and shows things in action.
If you prefer text to videos, here's an excellent Docker beginner series.
Once you are done learning fundamentals, I would highly recommend you practice. Just install Docker and try following this guided project.
🕳️ Blackhole of Linux
In case you didn't know, the /dev/null is regarded as a black hole of the Linux filesystem.
Whatever gets sent there, can't be traced back. And you will often find guides where the unnecessary output was redirected to /dev/null.
📊 ASCII Table is not complex anymore
When I tried reading the ASCII table for the first time, it seemed a complete mess so Sagar made a guide where he divided the whole table into small parts making it easy to digest:
🗞️ The happenings
💀 Suicide Linux
It's not harmful to you but dangerous for your system.
First, it is not a distro but a package. Once you install this package and execute any mistyped command, it executes rm -rf /.
As per the developer, it is more of a game where you have to master the command execution without any typo, or else your filesystem will be removed.
And it will remind you to execute every command with precision by displaying a warning Suicide Linux is installed.
More details on the project page.
Of course, it is not meant to be used on the main machine!
💡 Terminal Tip
I know you can use the up and down arrows to know the previous commands and execute them.
But that's not the most efficient way of executing the previous command.
Especially if it is 20-30 keystrokes far.
And in that case, you can use !{command}.
For example, I want to execute the previous cat command which will take 55 up-arrow keystrokes to reach that command from history.
But when I will use the cat command in the following fashion, it will execute the last cat command with flags too!
!cat

Installing Firefox as an apt package is still the second toughest thing in Linux. First is not to brag you use Linux!
