Tricks

Github web editor

You can edit a github repository by pressing . while viewing it. This will open up a VS Code web editor with the source of the repository.

Raspberry pi setup

Enable ssh

In /boot create a blank file called ssh

Enable wifi

In /boot create a file called wpa_supplicant.conf with the following:

Set up Apache + PHP

sudo apt update
sudo apt install apache2
sudo usermod -a -G www-data [USERNAME]
sudo chown -R -f www-data:www-data /var/www/html
sudo chmod -R 770 /var/www/html
sudo apt install php

Wttr.in

View the weather forecast via the command line

curl "wttr.in/Spokane?0"

ssh config

You can configure SSH servers in your ~/.ssh/config file, to set up easy to remember aliases for complex SSH configurations, for example:

Host tilde
   HostName tilde.town
   User dustin
   IdentityFile "~/id_rsa"

You can also set a port or an IP for the hostname:

Host srv
   HostName 123.456.0.1
   User dustin
   Port 1234

You can then SSH using the alias, such as these commands for those two examples above:

ssh tilde
ssh srv
