We will add here the slides from each talk and a link to a video, when these have been prepared for display on the net. Please check back if you are interested!

History of Arianne from 1999 to present day

Speaker

Abstract

I will try to summarize ten years of history in around 45 minutes. Explaining our projects, what they were and why we did them.

Concepts of Marauroa and how to use it

Speaker

Hendrik Brummermann (Germany)

Language

English

Target group

Developers

Abstract

In this talk I will present the basic ideas of the Marauroa engine (Actions, Perceptions, Messages, Events, Objects and Classes) and explain how to use them for your own games and programs. I will start with a very short introduction to UML class diagrams as they are a handy tool to describe object oriented structures.

The Amazing Stendhal Dictionary: Her Biggest Challenge Yet

Speaker

Katie Russell

Language

English

Target group

All

Abstract

Can anyone name all Stendhal NPCs and describe something interesting about what each does? Without preparation? (honestly... the speaker has no time to prepare...) If anyone can, the Amazing Stendhal Dictionary can! Marvel as she attempts to draw a map of the island and its dungeons, and take each region in turn, describing some history, each NPC's features, and some funny* anecdotes.

*No warranties. She thinks they are funny....

JUnit testing - how and why?

Speaker

Markus Keunecke (Germany)

Language

Target group

Developers

Abstract

It is well known that no application is bug free, so we need to find those errors to fix them. The earlier we find an error the less effort will be necessary to correct it. With tests that can be run repeatable you earn a lot safety for proceeding development. The tests can ensure that once working parts are not broken by changes of the ongoing the development. A freely available framework supporting such automated testing is JUnit. In this session we will tell why unit testing is a good idea and how we can use JUnit to test your code.

Review

Markus gave a talk on JUnit testing, and managed to make it sound not only vital to the code quality and stability of the project, but even fun too. He demonstrated how continuous integration (our hudson bot) and JUnit testing can work together to notify developers early of any problems. At the end of the talk at least one developer was heard to mutter Hm, I should add a test for that method I wrote last week.

How to develop quests in Stendhal

Abstract

This talk will explain how to develop quests in Stendhal. It uses the recently added Pied Piper quest as example.

Marauroa's Future

Speaker

Hendrik Brummermann (Germany), Markus Keunecke (Germany)

Language

English

Target group

Developers

Abstract

There is a number of very interesting and complicated things on the feature wish list for Marauroa. As you are probably aware of, KISS (Keep it simple, stupid) is one of the main principal of Marauroa. This of course does not mean that we cannot do complicated things. But it means that complicated things have to be well thought of and be broken into small parts. In this talk we will present ideas on how to archive the following "feature" and ask for you feedback and suggestion on the issues:

• No more lag caused by MySQL: A totally asynchronous approach to database access
• How to tunnel the Marauroa protocol over https and why it is more difficult than it seems to be on first glance (e. g. multiplexing with normal web traffic, not wanting to have 127.0.0.1 as client address in the logs)
• How to map a dynamic object model into a database table structure instead of a blob, so that we can use SQL for queries and updates (Yes, we know that Marauroa 1.0 failed and we will present a meta model approach that avoids those pitfalls)
• Integration of production and test system
• Steps toward cluster-support

Review

Hendrik and Markus together gave a talk on Marauroa's future. This covered both plans achievable in the short term and some more ambitious ideas. It was a talk aimed at developers and there were often questions and comments from the audience, which was really nice. Some of the topics, like asychronous database access and https multiplexing, seemed like they are both very useful and achieveable in the short term. Other plans like the meta model for storing objects and their attributes, values, and relationships, in the database, are really good plans and will need quite a lot of work to be introduced.

More Ideas for another time

• Using Tiled to create Stendhal maps
• Using Eclipse to develop Arianne projects
• Quest contribution for all skill levels
• What does Sourceforge.net offer Arianne?
• The GPL license - what is it and why does Arianne use it?

Templates

After I spent some time fighting Open Office Impress to create some slide layout, I thought I might share my tries:
