← Projects/Summer of Code/2007/Ideas You do not have permission to edit this page, for the following reason: The action you have requested is limited to users in one of the groups: Users, Administrators, trusted, KDEDevelopers. You can view and copy the source of this page. This page is an open list for ideas for the 2007 edition of [http://code.google.com/soc Google Summer of Code]. It will remain editable while the submission process is open. This list is not exhaustive. It is just a collection of some ideas. To get further ideas, you can also look at our [http://wiki.kde.org/tiki-index.php?page=KDE%20Google%20SoC%202006%20ideas list of ideas for the year 2006] Before proceeding, please read the [[Projects/Summer of Code/2007/Participation|participation instructions]]. They are useful for students and developers alike. == Notes on editing this page == Please respect the distinction between sponsored ideas and non-sponsored ones: sponsored ideas are those for which a KDE mentor has stepped up. Do not change the ideas listed in that section of the page. If you have an idea but you don't want to be a mentor, add it to the non-sponsored idea list. When making modifications to existing ideas, please consider whether you're changing it more fundamentally or just superficially. If your changes are substantial, you probably have an entirely new idea. Similarly, if your idea is modified and you feel it no longer reflects your original thought, please split the idea in two, restoring yours. Please use the [[Talk:Projects/Summer of Code/2007/Ideas|talk page]] if you want to discuss an idea. Finally, do '''not''' delete ideas without a reason for doing so (like, for instance, being contrary to KDE ideals, being completely unrelated to KDE, being unfeasible, etc.) -- you may want to state in the [[Talk:Projects/Summer of Code/2007/Ideas|talk page]] why you removed the idea. Do '''not''' re-add ideas that were removed without discussing first with the developers of the target application. == Past ideas == You may want to take a look at the [http://wiki.kde.org/tiki-index.php?page=KDE%20Google%20SoC%202006%20ideas ideas page for 2006]. Some of the ideas there are still valid today. == Project ideas with mentors (sponsored ideas) == These ideas were added by KDE developers willing to be mentors. You can contact the mentors listed for more information or clarification, if needed. You need not submit the exact proposal listed here — feel free to use it as inspiration. Even if you do change the proposal, you may contact the mentors to get their input. '''For mentors''': when adding an idea to this section, please include: * if the application is not widely known, a description of what it does and where its code lives * a brief explanation * the expected results * pre-requisites for working on your project * if applicable, links to more information or discussions * mailing list or IRC channel for your application/library/module * your name and email address for contact <!-- the division below is just a suggestion! --> === KDE Libs === === KPassivePopup === ''' Project Information:''' [http://api.kde.org/cvs-api/kdelibs-apidocs/kdeui/html/classKPassivePopup.html KPassivePopup] is the class that displays information next to taskbar icons, system tray icons or windows without interrupting the user. It is used both directly and by KNotify and is part of libkdeui. '''Brief explanation:''' Convert KPassivePopup to use QSvg for the frame etc. this would allow it to be much more flexible in its visual appearance and could allow us to eliminate the various custom implementations that are floating around. This would include examining these forks and ensuring the same functionality could be cleanly incorporated. '''Expected results:''' The intended result would be a single implementation of KPassivePopup that could be reused without copying code by applications such as Kopete that currently maintain their own versions. '''Knowledge Pre-Requisite:''' A prequisite would be knowledge of Qt/KDE and the ability to setup a KDE build environment. Knowledge of SVG would obviously be a big help.

Marble currently lives in http://websvn.kde.org/trunk/playground/base/marble/ and the author would like to see Marble be included with KDE-Edu soon. More information: [http://www.kdedevelopers.org/node/2429 the Marble description]. '''Brief explanation:''' To be properly integrated with other applications a 2D View for Marble will be needed in addition to the preferred 3D View (e.g. for merging functionality of KGeography and Marble). Three steps are suggested: # reuse the current rendering engine in 2D mode # write an optimized approach for the 2D case and thereby refactor parts of Marble (especially the texture mapping) # include adding proper access methods for applications and the user interface Depending on the knowledge of the applicant the refactoring part can be extended. '''Expected results:''' adding the 2D View Mode to Marble. Optionally, if enough time is available, integrate that view mode in another application like KGeography. '''Knowledge Pre-Requisite:''' basic knowledge of C++ is a pre-requirement. Basic highschool trigonometry knowledge would be helpful. Other useful skills, but not mandatory are: * Qt experience '''Mentor:''' Torsten Rahn <email@example.com>. '''Mailing list:''' The kde-edu mailing list: http://lists.kde.org/?l=kde-edu&r=1&b=200702&w=2 . === KDE PIM libraries and applications === ==== KPilot - Enhance Record based syncing ==== ''' Project Information:''' KPilot is the KDE application which synchronizes Palm OS PDAs with various KDE applications, including KMail, KAddressbook and Calendar. KPilot makes use of the pilot-link library to handle the interaction between the device and the conduits. These conduits are plugins which handle the actual synchronization of the items. For more information see [http://www.kpilot.org] '''Brief explanation:''' The vast majority of KPilot's conduits are record-based in nature. This means that the logical program flow for each of the conduits is very much the same in that they will each: # Open a Palm database # Retrieve either all records or just the changed records # Open a PC data store # Retrieve either all or changed records # Handle tri-directional syncing, conflict handling, and merging changed data # Then write the resolved data sets back to the PC and Palm data stores But the current conduit framework does not abstract this common functionality into a set of base classes as it should. This has resulted in a lot of duplicated code throughout KPilot's conduit base, and each conduit has its own way of handling this common functionality. Understandably, this has led to bugs in the syncing algorithms and has made maintainability of the conduits (and KPilot) a much more difficult thing than it should be. For every conduit, the maintainer has to learn how the actual syncing is done. To make matters worse, there are a couple of conduits which don't sync correctly because of a incomplete implementation of handling records. '''Expected results:''' The student will create an improved framework for KPilot's record-based conduits and (re)implement a (new) conduit as a proof of concept. # Documentation about the syncing process of a record based conduit. ## Sequence diagrams detailing sync logic for each of the major scenarios: ### HotSync ### FullSync ### Copy PC to Handheld ### Copy Handheld to PC ## Class diagram detailing: ### Inheritance hierarchy ### Class relationships # Implementation of the abstract record based conduit in the KPilot library. # (Re)implementation of a (new) Conduit as proof of concept. '''Knowledge Pre-Requisite:''' basic knowledge of C++ is a pre-requirement. Other useful skills, but not mandatory are: * Qt experience * Pilot-link experience '''Mentor:''' Adriaan de Groot <firstname.lastname@example.org>. '''Mentor:''' Jason 'vanRijn' Kasper <vR@movingparts.net>.

They are sometimes vague or incomplete. If you wish to submit a proposal based on these ideas, you may wish to contact the developers and find out more about the particular suggestion you're looking at. If there is no specific contact given you can ask questions on the general KDE development list email@example.com. See [http://www.kde.org/mailinglists/ the KDE mailing lists page] for information on available mailing lists and how to subscribe. These ideas don't have a "default" mentor yet. But, if chosen, we will assign one to you. Feel free to contribute more ideas as well. === Infrastructure === * A way to make bugzilla help in finding duplicated bugs. could be some kind of 'suggested related bugs' === KOffice === A list of KOffice ideas without mentors can be found at the [http://wiki.koffice.org/index.php?title=Summer_of_code KOffice wiki]. === A new design for contextual help (Whatsthis) === Implement Ellen Reitmair's, Olaf Schmidt's, Philip Rodrigues' plan for a new infrastructure for contextual help.
