2. Code as Craft
The construction of software should be an engineering
discipline. However, this doesn’t preclude individual
craftsmanship. Think about the large cathedrals built
in Europe during the Middle Ages. Each took
thousands of person-years of effort, spread over many
decades. Lessons learned were passed down to the
next set of builders, who advanced the state of
structural engineering with their accomplishments.
But the carpenters, stonecutters, carvers, and glass
workers were all craftspeople, interpreting the
engineering requirements to produce a whole that
transcended the purely mechanical side of the
construction. It was their belief in their individual
contributions that sustained the projects: We who cut
mere stones must always be envisioning cathedrals.
(Quarry worker’s creed).

8. Version Control
• myfile_v1.txt works
• Until you get to myfile_v42.txt

9. Version Control
• Wouldn’t it be great if there existed a
system that would track our versions for
us?!
• Sounds great, how does it work?

10. Create a Repository
git init

11. Do Stuff

12. Add New Files
git add myAwesomeFile.js

13. Commit changes
(to those files)
git commit

14. Let’s give it a shot

15. What happened?
working directory
git add
git add
git add
index
git commit
repository

16. Git
Cares about Doesn’t care about
Tracked changes Anything else
Committed changes
... seriously
(finalized)

17. But...
• Using command line interface (CLI) sucks
• False!
• I use Windows! My CLI sucks!
• Well, true.
