Note, we’re switching to an every-other week

Java SE 8 officially launched:

Java Tutorials page on Java 8

Great features as discussed on this tutorial

Also examples on the GitHub repo – https://github.com/winterbe/java8-tutorial

Cool new features include:

Lambda and functional interfaces (single method with @FunctionalInterface) – lots of built-in ones including ones from Guava

Extension methods – default methods (real code) for interfaces with the default keyword

References to methods and constructors with ::

Predicates – include test(), negate(), nonNull, isNull, isEmpty, etc…

Functions – single param, return a result, can be chained

Multiple Inheritance via Suppliers and Consumers

Enhanced Comparators

Optionals to wrap optional (nullable) values – to avoid NullPointerException

Streams – which can be attached to JDK collections and can have filters and sorting applied, can work on match, count, reduce, etc… Parallel streams are possible – i.e. spawn multiple threads

New Time (Date) API

Clock – access to current date/time, aware of timezone, can call Clock.systemDefaultZone().millis()

LocalTime, LocalDate, LocalDateTime, time Zones

Cool new repeatable annotations

Much more…

Increase your productivity by improving your health in 7 mins: 7 min high intensity workout anyone can do

Meet the machines that steal your phones data

Introduction to Apache Avro – serialization processing API that is used by Hadoop tools and that you can use yourself

Introduction

Tutorial Part 2

Ken was trying to remember this serialization project for Javascript

Haydle Hackathon Report – Fun with EmberJS

Low energy BlueTooth with new AdaFruit device

Let's talk Android Watches – Android Wear

Get Started with the Developer Preview
