be a catalyst for change
projects slowly get totally out of hand
remember the big picture
Good enough software

Communicate!
A large part of our day is spent communicating, so

None
get to the same frequency of your audience
choose your moment
choose a style
make it look good
be a listener
A pragmatic approach
By keeping these fundamental principles in mind during development, you
can write code that's better, faster, and stronger. You can even make it look easy
Every piece of knowledge must have a single, unambiguous, authoritative
representation within a system
DRY don't repeat yourself
- imposed duplication - inadvertent duplication - impatient duplication -
interdeveloper duplication How does duplication arise?
eliminate effects between unrelated things
Benefits
increase productivity
reduce risk
increase reversibility
every decision can be changed!
Coding DRY
keep your code decoupled
avoid global data
avoid similar functions
Single responsibility
must to be easy to test
Domain languages
"The limits of language are the limits of one's world"
- Ludwig Wittgenstein

program close to the problem domain
