Meeting for October is now posted (

Gavin King, the creator of Hibernate, and Stéphane Épardaud will be introducing their new JVM language, Ceylon (!

Format: Two talks of 60 mins each, with 30 mins break in between

Title: Ten Ceylon Idioms (50 mins)

Abstract: Ceylon is a new programming language for writing large programs in teams. Its unique static type system enables, and sometimes even requires, a different approach to some kinds of programming problems. In this session, we'll introduce the type system by presenting a series of simple examples, exhibiting common idioms in the language.

Title: Ceylon from here to infinity: the big picture and what's coming (50 mins)
Abstract: Ceylon is a new modern, elegant programming language for the JVM and JavaScript VM, designed for team work. But it's more than that, it is a full platform with modularity, an SDK, tools and IDEs.

We will present Ceylon the language, the platform, and its ecosystem. You will see everything from starting a new project in the IDE to publishing it on Herd, our module repository, including using the SDK. We will also discuss the ongoing Ceylon projects such as the build system, Vert.x integration or Cayla, the new web framework.

Finally we will discuss the plans for Ceylon 1.1, 1.2 and further.

Speakers: Gavin King and Stéphane Épardaud


Gavin King: Gavin King leads the Ceylon project at Red Hat. Gavin is the creator of Hibernate (, a popular object/relational persistence solution for Java, and the Seam Framework (, an application framework for enterprise Java. He's contributed to the Java Community Process as JBoss and then Red Hat representative for the EJB and JPA specifications and as lead of the CDI specification (

Gavin now works full time on Ceylon, polishing the language specification, developing the compiler frontend, working on the IDE, and thinking about the SDK and future of the platform. He's still a fan of Java, and of other languages, especially Smalltalk, Python, and ML.

You can follow him on G+ (

Stéphane Épardaud: From deep into the Nice mountains, Stéphane works for Red Hat on the Ceylon project.

Passionate hacker in Java, C, Perl or Scheme. A web standards and database enthusiast, he implemented among other things a WYSIWYG XML editor, a multi-threading library in C, a mobile-agent language in Scheme (compiler and virtual machines), and some Web 2.0 RESTful services and rich web interfaces with JavaScript and HTML 5.

Eager to share, he is a frequent speaker at various conferences such as the Scheme Workshop 2004, Nice University in[masked], many Java User Groups as well as the Riviera Java User Group he founded with Nicolas Leroux. A long-time open-source user and advocate, he is committer on RESTEasy, author of jax-doclets, stamps.js and various Play! Framework modules, and developer on various Ceylon projects for Red Hat.
