Be faster then rabbits
- 1. Faster than rabbits @BauerVlad, 2014
- 2. Questions / Problems • Why are we so slow? • How to increase development productivity? • How to extend the sphere of projects to develop? • How to develop High-Load web applications? • How to develop small / medium sized projects fast? • What can we do with it?
- 3. Java principles 1. It should be "simple, object-oriented and familiar" 2. It should be "robust and secure" 3. It should be "architecture-neutral and portable" 4. It should execute with "high performance" 5. It should be "interpreted, threaded, and dynamic” + WORA James Gosling, 1991-1995 What's the catch?

I have absolutely no idea how to write a programming language, I just kept adding the next logical step on the way.” (Rasmus Lerdorf)

- 25. GWT? • Using HTML in GWT - poor • Using CSS in GWT - poor • Separation of concerns - poor • Union of problems • Desktop != Web • Live examples: • Simba: GWT -> AngularJS • 30-50m to build big projects Client-side rendering
- 26. Rendering Server-Side • Has expensive (re)deploy • Needs a lot of hardware resources • Uses expensive caching • Needs additional REST API • Uses needed data set • Has framework components • Can split development team • Has got less JS code Client-Side • Has instant redeploy • Does not use a lot of server resources • Uses cheap caching • Has out-of-box REST API • Uses extended data set • Has framework components • Can split development team • Has got a lot of JS code vs
