raspi-config
============
- default login: pi/raspberry
- via "sudo raspi-config"
  - german-locale + german-keymap
  - activate sshd (and i2c for pi-usv)
  - reboot (for keyboard)
  - may disable sound (for stuff that uses gpio like matrix) (/boot/config.txt, dtparam=audio=off)
- apt install -y vim curl htop mc tmux git

manual stuff
============

- configure wlan
  - sudo iwlist wlan0 scan | grep FR36
  - sudo nano /etc/wpa_supplicant/wpa_supplicant.conf
    network={
        ssid="FR36"
        psk="testingPassword"
    }
  - sudo wpa_cli reconfigure
  - we should get a IP now: ifconfig wlan0
