I've noticed on several occasions that even people who work on a computer a lot don't know about the Shell (a.k.a Terminal) on their machines.
The Shell is an incredibly powerful tool that can help you with a lot of tasks and operations in your everyday life. It can drastically improve your productivity, you can manage servers from it, crunch huge amounts of data (searching, sorting, filtering, replacing), it allows you to automate annoying tasks and so much more.
I experience a lot of confusion and insecurities about it's use. It's not remotely as scary as people perceive it to be. And that's where I want to help.
They say learning through experience is the best way to go about it. I want to invite you to an interactive workshop to play with the command line and learn some basics to get your way around it. Afterwards you will be able to incorporate it's use into your workflow.
This session is not for hackers and developers only. I invite everyone who is curious about it and wants to feel like a ninja.

Quick and dirty solution to translate IPv4 and IPv6 CIDR blocks into a list of IPs for further digestion.
#!/usr/bin/env python3
# Translates IPv4/6 CIDR blocks into a list of IPs and writes
# them into a text file. Requires netaddr (pip install netaddr).
import netaddr
ip_list = netaddr.IPNetwork('192.168.1.0/21')
