This document discusses hacking the Sabbath in a creative and playful way by finding loopholes within the rules and restrictions of keeping the Sabbath holy. It categorizes 39 categories of work into four sub-categories and discusses using things like timers, lamps, thermostats, refrigerators, and stoves on the Sabbath without directly interacting with them. It encourages questioning restrictions and authorities in a spirit of inspiration and exploration, while never actually breaking any rules.

1. Hacking the Sabbath
AND KEEPING IT HOLY

5. Wrong

6. Right
“individuals who enjoy the intellectual challenge of creatively overcoming
limitations of [software systems] to achieve novel and clever outcomes.”
“in a spirit of playfulness and exploration”

7. Theology and Culture
Not a talk about religion
Not a talk to start a religious debate

9. Top Down View
In some theologies and cultures, there is a Sabbath
Particularly Judeo-Christian have a resting Sabbath
By resting, we mean not working
“On the 7th day god rested”

11. 39 Categories, in 4 Sub-Categories
Bread stuff (plants and cookings)
Garments stuff (clothes and mending)
Hides stuff (animals and cooking)
Construction stuff (building and fire)

12. Electricity and Fire
Electricomechanical switches that carry a live current
Could make a spark
◦ This is the FIRE
◦ There is one exception, but we are not talking about that
But that fire is not useful
So then science happened and completing a circuit is building
