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 
Miguel (Spain)
Language 
English
Target group 
All
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.
Review 
A very interesting presentation on the history of Arianne. Just a little note: The many screenshots of the map at the end may yield the wrong impression that there has been no progress in the last years. This, however, is far from true: Focusing on the quality of the world map and adding dungeons and quests instead of expanding the size of the upper world by adding mostly empty zones was an important design decision that brought the project a huge step forward in my opinion.

Stendhal: the past three years

Speaker 
Katie Russell
Language 
English
Target group 
All
Abstract 
Stendhal development over the past three years is something we are very proud of. This presentation covers the major milestones from 2007 through to 2010. It highlights Stendhal's strong community and recent achievements such as Arianne being chosen as Sourceforge Project of the Month.

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....

Review 
Wow, I am totally impressed. We have more than 200 NPCs in Stendhal, and Katie was able to name almost all of them with only the world map as help. I learned both some very interesting in game background of those NPCS and a number of curious facts about their creation.

Using GIMP to create Stendhal graphics

Speaker
Kiheru
Language 
English
Target group 
All
Abstract 
Review 
Kiheru introduced us into the magic of pixel working. Quite interesting to see how a pro uses GIMP, especially because you wouldn't see anything normally as pros mostly use short cuts. Kiheru showed us the steps to draw a tile for Stendhal from scratch. The result of this talk was a nice looking image of a column that could be used in the game.

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

Speaker 
Yuriy Krawtsow
Language 
English
Target group 
Contributors, Developers
Abstract 
This talk will explain how to develop quests in Stendhal. It uses the recently added Pied Piper quest as example.
Review 
Yuriy gave a quite wide overview on how to write quests for Stendhal. He showed where to find information on ideas for quests and their coding. Finally he gave an overview of his implemented quest about the pied piper which can be seen as Stendhal's first kind of automatic raid.

Marauroa's Future

Speaker 
Hendrik Brummermann (Germany), Markus Keunecke (Germany)
Language 
English
Target group 
Developers
Abstract 
There are 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 principles 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 out and should be broken into small parts. In this talk we will present ideas on how to achieve the following "features" and ask for your feedback and suggestions 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 asynchronous database access and https multiplexing, seemed like they are both very useful and achievable 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.

Templates

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

Note: Use View | Heading/Footer... to add the title of your presentation into the middle section of the footer

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?
