Raspberry Pi 2 official touchscreen display

Installed the official touchscreen on one of my Raspberry Pi 2 devices.

It was a easy, I followed the guide Raspberry Pi Official DSI Display Assembly to install the hardware. After the hardware setup of the display I connected a USB cable for powering the Raspberry pi according to the guide in The eagerly awaited Raspberry pi display

Starting up the the device the display was working, but no touchscreen was enabled. To get the touchscreen to work I did the upgrade explained in the guide:
$ sudo apt-get update
$ sudo apt-get upgrade
$ sudo reboot
After the update the display worked as expected.

Raspberry Pi 2 WiFi with WEP Open System

Tried to get the wifi going with the GUI in Raspbian but it would not start working.

Ended up googeling and found this forum post on the Raspberrypi forum. that explained how to correctly setup the file for WEP with open system:
Found an blogpost explaining how to edit the file:
$ sudo nano /etc/wpa_supplicant/wpa_supplicant.conf 
changed myssid to the my wifi network ssid and changed the mywebkey to the correct key.

did a reboot
$ sudo reboot
and now it works!
