add favorite products? one click checkout only show in-‐stock products?
I don’t even like my mouse. My mouse was
crying… omg!
architecture rant bit.ly/unclebobarch bit.ly/screamarch
• Release Reuse • Common Closure • Common
Reuse • Acyclic Dependencies • Stable Dependencies • Stable Abstrac2ons Forgo%en SOLID principals What you hear about • Single Responsibility • Open/Closed • Liskov Subs2tu2on • Interface Segrega2on • Dependency Inversion
common closure Classes that change together are packaged together.

• Tasking • Chat (XMPP) Feature Themes walk the
walk Context • Air Force • Old: Thick Client • New: Single Page App • HTML5(ish) + Javascript • Java
Why call them modules? S2ll a lot of noise

Focus Drill into chat feature Focus
other effects • Conven2ons Within Features • Responsibility Viola2ons
Obvious • Ramp up • Small, Simple Interfeature Collabora2on “Ah consistency, the path to simplicity and the bane of innova6on. Choose wisely” ~ me, on twi<er
