HTML5 animations

• CSS3 et SVG: declarative
• Canvas et WebGL: programative

Memory System

• Guy working in High frequency trading
• Performance inside CPU
• HDD vs SSD

Continuous Delivery

• Feature toggle
• DB updates
• Blue / Green deployments

Continuous Delivery

GWT offline

• Cache manifest
• SQLite for storage
• Offline authentication (sha-1)
• Data synchronisation, conflicts management

Tools

• Gradle
• IDE & productivity
• TomEE
• Software factory

Scala / JVM languages

Java 8 - lambdas

Example with Java 7

Runnable job = new Runnable() {
    @Override
    public void run() {
        System.out.println("Hello Zanox");
    }
};
                

Example with Java 8 and lambdas

Runnable job = () -> {
    System.out.println("Hello Zanox");
};
                

Example 2 with Java 8 and lambdas

List strings = Arrays.asList("hello", "world", "!");
Collections.sort(strings, (s1, s2)-> s1.compareTo(s2));
System.out.println(strings);

Java EE 7 - Highlights

AngularJS

• Declarative vs imperative
• 2 ways binding / watches
• Dependency Injection
• Templates: pure html
• MVC
• Directives
• Unit Test (karma)
• End to end tests (synchrone test for asynchron app)
• Tools (yeoman, grunt, bower, etc...)
