The document discusses key concepts of object-oriented programming including classes, objects, methods, encapsulation, and inheritance. It provides examples of defining classes with members, creating objects from classes, and using access specifiers. The document also covers constructors and how they are used to initialize objects when they are created.

This presentation forms part of a tutorial on learning Javascript foundations. It is an introduction to the basic concepts of object oriented programming and using Javascript objects to organise code.
Constructors, Destructors, call in parameterized Constructor, Multiple constructor in a class, Explicit/implicit call, Copy constructor, Dynamic Constructors and call in parameterized Constructor
Presentation derived from the "What's new in Python 2.6" document on http://www.python.org/ including much reformatting for presenting and presenter notes.
Please download the Keynote original - that way the presentation notes aren't burned into the slides.

Poche chiacchiere e tanto codice per cercare rendere la nostra vita di
sviluppatori più divertente.
Parleremo di JAX-RS, le annotazioni, l'MVC che mette a disposizione e
l'integrazione di Jersey con Guice.
Useremo AOP per gestire log, transazioni e con l'aiuto di Infinispan
limiteremo le chamate concorrenti sul nostro cluster.
A Java agents are pluggable self contained components that run embedded in a JVM and intercept the classloading process. They were introduced in Java 5 along with the powerful java.lang.instrument package. Java agents can be loaded statically at startup or dynamically (programmatically) at runtime to attach to a running process in a fail-safe fashion.
Java agents were an awesome addition to the JVM as it opened a lot of opportunities for tool designers and changed Java tooling landscape quite drastically. In conjunction with Java bytecode manipulation libraries it is now possible to do amazing things to Java classes: we can experiment with programming models, redefine classes in runtime, record execution flow, etc.
The presentation provides an overview of Java agents’ functionality along with the usage examples and real world experiences. You will learn, how to implement an agent and apply Instrumentation API in combination with bytecode manipulation libraries to solve interesting tasks.
Not so long ago Microsoft announced a new language trageting on front-end developers. Everybody's reaction was like: Why?!! Is it just Microsoft darting back to Google?!
So, why a new language? JavaScript has its bad parts. Mostly you can avoid them or workaraund. You can emulate class-based OOP style, modules, scoping and even run-time typing. But that is doomed to be clumsy. That's not in the language design. Google has pointed out these flaws, provided a new language and failed. Will the story of TypeScript be any different?
