"I have always found that plans are useless but planning
is indispensable." - Dwight D. Eisenhower
The Codebase Ruby 2.1 Rails 2.3 Postgres, Redis, Memcached Started
in 2008 60 contributors ~128k lines of application code
#TODO: redo this
How to add features
1. Plan out the feature
1. Plan out the feature Have developers involved in the
planning
1. Plan out the feature Have developers involved in the
planning ! Let your unique development concerns be known
1. Plan out the feature Have developers involved in the
planning ! Let your unique development concerns be known ! Make it a conversation
2. Do a technical kick-off
2. Do a technical kick-off What new data models do
we need? ! What needs to be refactored? ! What might the challenges be?
3. Be prepared to do something else entirely
4. Write lots of tests, especially for things that already
exist
5. Document Things
Build awesome things
# because the "update_attributes!" does not behave as expected, we
need this def update_attributes_is_broken_with_nested_attribute_validations_in_rails ... end
How to execute refactors
Treat them like features
1. Plan out the refactor
2. Do a technical kick-off
3. Write lots of tests, especially for things that already
exist
4. Document Things
Build awesome things
