Transcript

  • 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?
  • 4. + Java EE 8JSRs JEE evolution
  • 5. spring.io

  • 9. PHP: Hypertext Preprocessor • Original name: Personal Home Page Tools • Paradigms: imperative, functional, object-oriented, procedural, reflective • Short time to market • Easy integration • Flexibility • Availability of resources “I don’t know how to stop it, there was never any intent to write a programming language. 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
  • 27. Client-side • Demand (Hot Google searches): • Java: about 230 000 000 results • JavaScript: about 916 000 000 results • PHP: about 3 140 000 000 results
