How to connect to UMass Eduroam wifi with a Raspberry Pi running Raspbian

How to connect Raspberry Pi to UMass Eduroam

Open up a terminal and move into the directory holding the wpa_supplicant config file.

cd /etc/wpa_supplicant

You may want to backup your config file before you do anything just in case.

sudo cp wpa_supplicant.conf ~/Desktop/wpa_supplicant.conf

How to stream a webcam to a web browser in Ubuntu

Grr this took hours to figure out. I was trying to install MJPG-streamer and running VLC command lines and all this crap but nothing worked.

First install motion:

~> sudo apt-get install motion

Then create a config file:

~> mkdir ~/.motion

~> nano ~/.motion/motion.conf
