DevDay Napoli - Scala - Dalla Svizzera con furore

DevDay
DevDay

Basato sulla JVM Scala mette insieme OOP e Functional Programming per creare un linguaggio completo, conciso, funzionale, type safe ed estremamente versatile per qualsiasi tipo di applicazione. In questa presentazione cercheremo di addentrarci in questo linguaggio partendo da alcune delle caratteristiche sintattiche di base passando per esempi di programmazione funzionale fino ad arrivare ad esempi apparentemente incomprensibili di codice reale. Rosario Renga Lavoro tra Italia e Olanda in ambito Big Data per Vandebron, start up impegnata nel campo dellenergia rinnovabile. Ho lavorato con Java, .Net, Salesforce e tanto altro. Appassionato di tecnologie web, videogiochi e musica, passo le mie giornate tra Scala e .NET. Scrum master a tempo pieno mi piace scoprire sempre nuovi linguaggi di programmazione e capire come sfruttarli al massimo. Ho sempre cercato di condividere e accrescere le mie conoscenze, tramite blog, workshop e conferenze. Se ti va di fare quattro chiacchiere da Nerd a Nerd portami una birra e inizia a parlare :)

Historical notes The design of Scala started in 2001 at the cole Polytechnique F辿d辿rale de Lausanne by Scala was released publicly in early 2004 on the Java platform. A second version (v2.0) followed in March 2006 Martin Odersky
Main reasons behind scala Challenge: Achieve software side scalability avoiding concurrency and parallelism problems
Main reasons behind scala Challenge: Achieve software side scalability avoiding concurrency and parallelism problems Parallel programming: Execute programs faster on a parallel hardware Problem: Mutable state Non deterministic execution Concurrent programming: Manage concurrent execution explicitly Problem: Mutable state must be managed explicitly

My Experience
My experience - The beginning Software Developer Object Oriented Almost zero functional programming experience Java and .NET world
My experience - The beginning
My experience - I saw the light in the tunnel Immutability Everything is a function Everything must return a value Think functional
My experience - Lets code! https://github.com/MeMpy/scala-playground
Some other features
Scala in the real world Scala is Reactive
Scala in the real world Scala is Big Data
Scala is Web development Scala in the real world
Questions?
git Java development kit ( JDK 8 ) Sbt ( probably optional ) IntelliJ Idea Community Edition Nu poc e genio What you need to run the project
References Official documentation Coursera Scala courses Scala blog for Neophyte Scala center Lightbend for scala .....stackoverflow
Thanks and happy learning
