APIs, like diamonds, are forever
Aim for thread safety
Alone time
Assert against improper behaviour
Automate the entire release and deployment process
Be curious
Beware of anemic domain models
Brutal Transparency
Comment with care
Dare to say no
Deal with non-functionals
Develop for security
Diagnose before cure
Don't Repeat Yourself
Done = Live!
Eliminate waste
Fail fast
Favor composition over inheritance
Favor continuous improvement over delayed perfection
Find the root cause
Focus on flow
Get the team in a rhythm
Have fun
If it hurts, do it more often
If something is too complex to understand, it must be wrong
If you are stuck developing for more than two minutes, you MUST ask somebody else
Improve practices, don't just follow the recipe
Integrate early
It ain't over till it's done
Judge on content, not on authority
Keep the build clean
Keep your hands off the machine
Keep your logs clean
Learn a new language every year
Leave the campground cleaner than you found it
Make it visible
Make it work Make it right Make it fast
Make room for exploratory testing
Master your tools
Maximize cohesion Minimize coupling
No blame, but no mercy
No broken windows
No change without a failing test
No multitasking
One change at a time
One feature at a time
Pair programming
Prefer rich modes of communication
Prevent your code base from turning into a museum
Remember the fallacies of distributed computing
Respect the zone
Review code
Run tests automatically
Separation of concerns
Share the design
Sleep easy on a green build
Split functionality into small units
Start with acceptance criteria
Take time to tackle tech debt
Test Driven Development shapes design
Testing is a shared responsibility
Tests are Specifications
Tests should be fast, reliable and independent
Think of code and test as one
Three strikes and you automate
Timebox the unknown
When you don't have time to test everything, you're building too much
Work in small increments
Work on stories when they're ready
Write code that humans can easily understand
Write small and focused interfaces
You build it, you run it!
You get what you measure
Your solution should not be more complicated than the problem
