Agenda

Things to Forget

• First normal form

• Waterfall model

• Single server deployment

• Single language skill

• Build everything from scratch

• Build custom infrastructure

Things to Learn• Agile, API Design• UI Design, Javacript, HTML5, CSS3• A/B Testing• Open Source, Open Standards• Architecture, Distributed Computing • Cloud Platforms and APIs• Multiple types of languages (imperative, object, functional, logic)• Ability to encapsulate domain knowledge in a DSL• Build on the shoulders of giants: reuse, rest APIs• Pick your battles, choose what you need to build yourself to add

value• Learn to live in a box (embrace platform limitations) to think

outside the box• Use an App Store for distribution
