Take a good idea …
… and make working software
Day 0
What will you do?
“Dear ___,
Saw your presentation at ___. I liked the Q&A and learned a bunch of new things.
I have a favor to ask. I’ve joined a NY startup, ___. We’re just starting, and I am
hoping to do things ‘right’ from the start. I was wondering whether I could borrow
someone’s time at ___ next week (yours or someone who works for you) and maybe
bring 1-2 people with me to see how your code and tooling is organized.
Sincerely,
-Me”

Demo Day!
Developers know how to get started.
Developers can commit code with a peer code review.
Every time a developer checks in code, continuous integration runs tests and
e-mails results to the team.
Every time continuous integration executed tests successfully, staging gets
the latest code.
We can deploy to production by hitting a button!
