19.00 Opportunistic Networking with Android
In this work we present a middleware architecture for a mobile peer-to-peer content distribution system. Our architecture allows wireless content dissemination between mobile nodes without relying on infrastructure support. Contents are exchanged opportunistically when nodes are within communication range. Applications access the service of our platform through a publish/subscribe interface and therefore do not have to deal with low-level opportunistic networking issues or matching and soliciting of contents. Our architecture consists of three key components. A content structure that facilitates dividing contents into logical topics and allows for efficient matching of content lookups and downloading under sporadic node connectivity. A solicitation protocol that allows nodes to solicit content meta-information in order to discover contents available at a neighboring node and to download content entries disjointedly from different nodes. An API that allows applications to access the system services through a publish/subscribe interface. In this work we describe the design and implementation of our architecture. We also discuss potential applications and present evaluation results from profiling of our system. Ólafur Helgason is a PhD student at the Laboratory for Communication Networks at KTH, Stockholm. His research focuses on how content can be disseminated opportunistically in mobile wireless networks and how mobility affects wireless communication. Ólafur likes the free and the open: software, beer and the great outdoors. Ólafur Helgason, KTH

18:30 TDD genom coding dojos
Although the theory of how to do Test Driven Devel- opment can be explained in a few sentences, mas- tering the skill takes substantial time and effort. Going to a Coding Dojo is a way to meet with other programmers in a “safe” environment in order to engage in deliberate practice, and learn by doing. We would like to talk about our experiences using the Dojo form and Kata exercises to teach the skills of TDD to professionals who want to improve the quality of their work. We have found that different Katas can be used to teach different aspects of TDD, for example some are more suitable than others for a mockist ap- proach. The skill level of the people in the group, and the programming language being used also make a difference. We have also found that it can be challenging to keep a group together and all learning new things at each meeting. In this talk we will share some insights about what works, what doesn’t, and what can be achieved using the dojo form. Our hope in giving this talk is to inspire others to start coding dojos, and improve the practice of programming.

19:20 Flexklient med Spring / Hibernate / Java backend
I februari 2008 gjorde Adobe FlexSDK och BlazeDS till open source och i april ett par månader senare började Extenda arbeta med tekniken. Olov kommer i presentationen ge en introduktion till kombinationen Flex/Java/Spring/Hibernate. Utifrån en ”early adopters” erfarenhet kommer presentationen också att göra djupdykningar i mer avancerade problemställningar som exempelvis hantering av persistenta objekt på klientsidan. Dessutom kommer Olov att beröra en del olika stödramverk.

17:05 Readable Web Application Tests with Selenium
Selenium RC allows you to test your web application through the browser and simulate user actions in a very realistic manner. It also has a handy Firefox plugin to help you to record tests in Java. Unfortunately, I've found that if you just use these tests straight off, you quickly end up with a test code maintenance headache. In this presentation I'll be looking at several approaches and additional tools which can help you make your tests more readable and robust Emily Bache, ELABS

19:05 Introduktion till Git
Git skapades av Linus Torvalds när de som utvecklar linuxkärnan behövde ett nytt versionshanteringssystem. Det används av många open source-projekt och många migrerar nu sina repositorys till Git från till exempel Subversion. Varför då kan man fråga sig? Git är distribuerat, varje repository har fullständig historik, och detta gör bland annat att man inte är beroende av nätverksaccess eller en central server. Det är går väldigt lätt och snabbt att skapa nya brancher och att merga. Presentationen kommer ge en introduktion till hur Git fungerar och ge de som inte provat Git en anledning att testa själva.

19:45 Enterprise Architecture med Master-Slave principen
När flera IT-system ska fungera ihop genom att utbyta information och samverka på olika sätt, i en s.k Enterprise Architecture, är det viktigt att tidigt bestämma vilket system som äger vilken information och affärslogik. I det här föredraget utgår Peter ifrån koncepten i Domain-Driven Design för hur man kan beskriva domänmodellen och implementera i en fragmenterad systemflora.

19:15 Vaadin - Rich web applications in plain Java without plugins or JavaScript
This presentation shows how easily you can create desktop-like web applications in plain Java without any HTML, XML, plugins or JavaScript. You will learn how to avoid the most typical problems in web application development by using a desktop-like programming model on server. Apache-licensed Vaadin framework is used to leverage Server- Driven RIA (SDR) architecture that allows you to focus on application logic and forget cross-browser issues.
- Server-Driven RIA architecture is introduced. A comparison between traditional web application architecture, client-side RIA architecture and SDR is done.
- A brief introduction to Apache-licensed Vaadin framework is given.
The toolkit is compared to Google Web Toolkit and the integration between the products is explained.
- A desktop-like web application is created from scratch to give a hands-on experience on SDR.

17:35 Ajax Push for Revolutionary Enterprise Applications using ICEfaces (engelska)
Emerging Ajax techniques, variously called Ajax Push or Comet, are bringing revolutionary changes to Web application interactivity, truly moving the Web into the Participation Age. This session provides a detailed introduction to the Asynchronous Web and its application to social computing, explaining the underlying protocols, the challenges for application servers, portals and developers and the high-level techniques available to application developers. Attendees will take away the information they need to add multi-user collaboration and notification features to their application. The session provides a lot of inside views and demos using ICEfaces, an open source Ajax framework based on JSF as well as Liferay, an open source enterprise portal solution where portlets built on ICEfaces can leverage the user experience and Ajax Push can be used as a form of IPC (Inter Portlet Communitcation).

MICHA KIENER is responsible for Research and Innovation at mimacom ag, a company specialized in Java and open source technology applying agile methods. He is initiator and main committer of the open source framework edoras, committer of Liferay, an open source enterprise portal solution and participating in the development of ICEfaces, an Ajax-framework based on JSF. After his diploma thesis in artificial intelligence, he focused on Java, especially in light-weight, model- and process-driven architecture and framework developing.

19:15 Watching the logs roll by (Engelska)
25% of developers say that their JEE projects take over 2 minutes to deploy, every time they want to see their changes. Since on average we deploy 5 times an hour, we're watching the logs roll by, or switching to email and losing focus, for more than an hour every day. Ouch. That's painful! In this talk, Jevgeni Kabanov will highlight 3 key techniques that you can start using immediately to drop the time from hitting Ctrl+S to refreshing your browser down to less than one second. We will start by discussing exploded development and some shortcuts you can take to eliminate the build scripts from your everyday life. The we will review some ways to bypass or speed up redeployment. We'll take a look at JEE redeployment, OSGi modules, special framework support that exists in Grails, Seam, Tapestry5 and RIFE, and JVM HotSwap. We'll cover what you can do for free, and introduce a class reloading JVM plugin called "JavaRebel", that solves the problem for peanuts. After this talk, you'll walk away with a clear idea of at least 3 ways to reduce your turnaround, and measurably save your team at least an hour per day.
Jevgeni Kabanov, ZeroTurnaround
For the last five years, Jevgeni has been the R&D lead of Webmedia, Ltd, the largest custom software development company in the Baltics. During that time, he has spearheaded the movement to decrease the development turnaround time. As a result, two products (JavaRebel and JspWeaver) were developed under the trademark ZeroTurnaround, of which Jevgeni is the technical lead. Both projects contributed directly to the immense reduction in turnaround time. Jevgeni is also a co-founder of the open source Aranea project.
