Possible projects  External 1. Join and contribute to an open source project of your choice  Internal to ETH 2. Join and contribute to a project internal to ETH (can be open or closed source) 3. Participate to a project suggested by the assistants (open source) Languages in Depth series: Java Programming 2

Open source collaborations Examples of projects from the last two years course iteration http://azureus.sourceforge.net/ http://www.tegmento.org/gpsylon/ http://maven.apache.org/ www.eclipse.org http://freeguide-tv.sourceforge.net/ http://tapestry.apache.org/ http://www.jonelo.de/java/jacksum/ http://www.hattrickitalia.org/gham/ http://paloalto.dnsalias.net/ http://www.junit.org/ cacms_home/index.html http://freemind.sourceforge.net/ http://www.columbamail.org/drupal/ Languages in Depth series: Java Programming 3

More open source collaborations Further suggestions for collaborations  www.db4o.com  www.springframework.org  http://www.springframework.org/projects (14 projects)  http://www.jpox.org/  http://sourceforge.net/projects/prevayler/ Practical hints  Check the number of active developers  Check the recent project activity  Check the project mailing lists/wiki’s Languages in Depth series: Java Programming 4

Internal projects  Propose a project from another chair  Program a web-based, turn-based, two-player strategy card game, using the Spring framework and db4o OODBMS  Example: something like Magic The Gathering card game (www.magicthegathering.com), or a card game you like that still does not have an online version.  For an inspiration on card games have a look at www.boardgamegeek.com Languages in Depth series: Java Programming 5

Restrictions for all projects  Language: Java  If joining an external project, must be > 5000 loc  Minimal facilities should be available  SVN or CVS  Web site  Documentation should include unit tests  Groups of 2 or 3 people Languages in Depth series: Java Programming 6

Important deadlines  April 2 nd : choose a project and create an entry on the course wiki together with a new project on origo  April 16 th : devise a document describing what is planned  May 21 st and May 28 th : presentations, max 3 slides each  May 28 th : devise a report describing the achievements and possible issues encountered Languages in Depth series: Java Programming 7

Project grading  Project overall requirements doc  15% of the project grade  Language, clarity and style are important factors  A template will be provided  Implementation  70% of the project grade, of which  Contribution quantification: 50%  Documentation: 20% (includes unit tests)  Final report  15% of the project grade  Reminder: project grade is itself 50% of the exam grade Languages in Depth series: Java Programming 8

Assessment • Motivation as an indicator of performance • Questionnaire on Current Motivation (QCM) [1] (given at beginning and end of project) [1] F. Rheinberg, R. Vollmeyer, and B. D. Burns. QCM: A questionnaire to assess current motivation in learning situations. Diagnostica, 47:57–66, 2001. Languages in Depth series: Java Programming 12

Analysis of QCM Project variant 1 t-Test for paired sets QCM t2 QCM t1 t-Tests for independent sets QCM t2 QCM t1 t-Test for paired sets Project variant 2 Languages in Depth series: Java Programming 13

Summary of results • Open source projects create a more unstable situation than traditional projects (many significant changes over time) • Students seem to be more intimidated by open source projects, but probably more interested in the end This time: More on why you choose your favorite option Languages in Depth series: Java Programming 14
