58 bytes of CSS to look great nearly everywhere

When making this website, i wanted a simple, reasonable way to make it look good on most displays. Not counting any minimization techniques, the following 58 bytes worked well for me:

main {
  max-width: 38rem;
  padding: 2rem;
  margin: auto;
}

Using Python's built-in defaultdict we can easily define a tree data structure:

def tree(): return defaultdict(tree)

That's it!

Virtual hosts

Let's say you want to host domains first.com and second.com.

Create folders for their files:

scaryguy

-- Firstly, remove PRIMARY KEY attribute of former PRIMARY KEY
ALTER TABLE <table_name> DROP CONSTRAINT <table_name>_pkey;

-- Then change column name of  your PRIMARY KEY and PRIMARY KEY candidates properly.
ALTER TABLE <table_name> RENAME COLUMN <primary_key_candidate> TO id;

FollowMeDown

In any GNU/Linux distribution, which have a package manager on board, is recommended to install software by using "packages".

Building from source
Step 1. GPG key

The first thing you need is generate a gpg key. 
Package will be signed by this key. 

Run this commands in your terminal:

NB: This document describles a 'Old-School' way of using Yubikey with SSH

Modern OpenSSH has native support for FIDO Authentication. Its much simpler and should also be more stable with less moving parts. OpenSSH also now has support for signing arbitary files witch can be used as replacement of gnupg. Git also supports signing commits/tags with ssh keys.

Pros of FIDO

• Simpler stack / less moving parts
• Works directly with ssh, ssh-add and ssh-keygen on most computers
• Simpler
• Private key can never leave the FIDO device

Cons of FIDO

Creating a .deb Package

This creates a package which runs an install.sh which copies a file somewhere the below is entirely incorrect. Hopefully I'll get around to fixing it tip: this would install to the root dir & the relative path to ./install.sh would be wrong

go to project directory

cd /path/to/project
