Last, third post with my notes from GeeCON 2014 conference. Pretty short? I am not going to justify myself, but it was third day and everyone was a bit tired after two intensive days and nights in Cracow.
Tomasz Kowalczewski – Reactive Java
- Something almost “reactive” is already in JDK8: Completable Future, more reading: “Java 8: Definitive guide to CompletableFuture”
- RxJava has nice DSL allowing to configure observables in elegant way
- Project has good wiki, worth to dive deeper
- Observables can be easily converted to Iterator (good for step-by-step migrations)
Tom Bujok – 33 things you want to do better
- (didn’t attend this one), but there are very good slides available
Sander Mak, Paul Bakker – Modular JavaScript
Sandro Mancuso – Crafted Design
- Controller only controls the flow, usually only invokes use_cases
- use_cases, package for logic/features
- Packages by feature
- There were too many diagrams hard to describe in text so you should really check slides
Michael Feathers – Beyond Error Handling
- Book “Growing Object-Oriented Software, Guided by Tests”
- We shouldn’t pass nulls inside the application
- “Do not check for stupid everywhere, check for stupid at the door”
