Technology is not the exclusive province of corporations.

Coding can be recreational, even enjoyable when it is done for reasons other than pure profit and away from the frenetic pace of commercial software development teams.

Mathematics is the language we use to describe the Universe.

These machines ("computers") are a window into a modeling construct where these mathematical frameworks can represent all the worlds humanity can ever imagine.

How to add pictures to the raspi

Manually

Open terminal window
scp picture-name.jpg [email protected]:/media/pi/Lexar/pictures

Edit file common.yaml

iac_workshop/puppetlabs/code/environments/production/data/common.yaml needs two new lines.
