Guidelines

Information for Students

These ideas were contributed by our developers and users. They are sometimes vague or incomplete. If you wish to submit a proposal based on these ideas, you are urged to contact the developers and find out more about the particular suggestion you're looking at.

Becoming accepted as a Google Summer of Code student is quite competitive. Accepted students typically have thoroughly researched the technologies of their proposed project and have been in frequent contact with potential mentors. Simply copying and pasting an idea here will not work. On the other hand, creating a completely new idea without first consulting potential mentors rarely works.

When writing your proposal or asking for help from the general KDE community don't assume people are familiar with the ideas here. KDE is really big!

If there is no specific contact given you can ask questions on the general KDE development list [email protected]. See the KDE mailing lists page for information on available mailing lists and how to subscribe.

Note

These are all proposals! We are open to new ideas you might have!! Do you have an awesome idea you want to work on with KDE but that is not among the ideas below? That's cool. We love that! But please do us a favor: Get in touch with a mentor early on and make sure your project is realistic and within the scope of KDE.

Ideas

Kalendar

Project: Calendar Invitation

Brief explanation: The goal is to make it possible to send calendar invitation from Kalendar and also handle incoming invitations. This includes showing the free busy information from the attendees. Part of this features are already implemented in the C++ core but needs to be hooked up in the UI and others will require more work.

Expected results: Being able to manage all your meetings with Kalendar and make sure this is unit tested :)

Duration: ~350 hours

Knowledge Prerequisite: C++ is highly recommended, this is a complex code base

Mentor: Carl Schwan and Claudio Cambra (contact us in #kalendar:kde.org on Matrix)

Project: Improved multiplatform support

Brief explanation: Kalendar works great on Linux, but due to our dependency tree it is tricky to get it to build on Windows, and we do not have any current builds for macOS. For this project you will work on improving our support for either or both of these platforms and helping them become first class citizens for Kalendar. This will likely involve working on related projects like Akonadi.

Expected results: Working daily builds of Kalendar on Windows and/or macOS, depending on chosen project duration.

Duration: ~175 hours for one platform or ~350 hours for both platforms

Knowledge Prerequisite: C++ and CMake will be used extensively

Mentor: Claudio Cambra and Carl Schwan (contact us in #kalendar:kde.org on Matrix)

Project: Mail integration

Brief explanation: The goal is to make Kalendar not just a great calendaring application, but also a great mail application. We have basic email lists and a basic viewer working, but there is a huge amount of work still to do here: threading, editing, sending, and a lot more. A lot of this will not have to be done from scratch thanks to Akonadi (i.e. email retrieval and sending), but a lot of it will (i.e. threading).

Expected results: Kalendar should be a nice mail app :)

Duration: ~350 hours

Knowledge Prerequisite: C++ is required, QML will be needed but can be learned on the go if one has some JS experience

Mentor: Carl Schwan and Claudio Cambra (contact us in #kalendar:kde.org on Matrix)

Project: Implement calendar availability

Brief explanation: The short version is that you will need to implement RFC 7953 in Kalendar. The long version is that this availability extension definde by this RFC allows to define available and unavailable time periods. This is then helpful when trying to schedule a meeting with someone (see above tasks) as you will then be able to see then and avoid scheduling a meeting at that time. Implementation you will first need to add support for this in KCalendarCore for it and then expose this to the user interface so that user can modify their availability.

Expected results: Being able to configure my availability in Kalendar

Duration: ~175 hours

Knowledge Prerequisite: C++ and QML is recommended

Mentor: Carl Schwan and Claudio Cambra (contact us in #kalendar:kde.org on Matrix)

Project: Accessibility improvements

Brief explanation: It is a general KDE goal to make our applications accessible to everyone, including those who may require using their computers with keyboard navigation and screen readers. Kalendar needs a lot of work in this regard, particularly regarding navigation within the calendar views and around the application.

Expected results: Keyboard navigation throughout the entirety of Kalendar is expected, as well as use with screen readers. Further ideas for accessibility-related improvements are a big plus.

Duration: ~175 hours

Knowledge Prerequisite: QML will be required for this task, and you will likely need to use some C++ too.

Mentor: Claudio Cambra (contact me in #kalendar:kde.org on Matrix)

Okular

Okular is a universal document viewer developed by KDE. Okular works on multiple platforms, including but not limited to Linux, Windows, Mac OS X, *BSD. Contact the Okular developers.

Project: Okular user interface for e-ink tables (PineNote)

Brief explanation: e-ink tables are special given their "low" refresh rate.

We would need to create a new Okular user interface (based either in the mobile or the dekstop one) to accommodate for the unique features of those kind of displays.

We will probably arrange to get a device loaned if someone gets selected for this project.

Expected results: A new Okular user interface that works well with e-ink tablets.

Knowledge prerequisite: C++, probably QML.

Duration: 350 hours.

Mentor: Albert Astals Cid [email protected]

Project: Improve Okular for Android

Brief explanation: Okular has an Android version it needs some improvements.

Poppler, the library that Okular uses for PDF rendering is missing a "find me a font given a font name" backend for Android. We should use new new Font API introduced in Android API 29 to do that.

The Icons in Okular-Android are not being rendered, there is something in KDE Frameworks interfering.

You should have an Android device with Android >= 10 for testing

Expected results: New Font API in poppler and icon rendering fixed.

Knowledge prerequisite: C++

Duration: 175 hours.

Mentor: Albert Astals Cid [email protected]

Sustainability

Project: Measuring Energy Usage Remotely with Online Portal

Brief explanation: The goal of this project is to create an online portal that allows developers to remotely access and control the energy measurement lab at KDAB Berlin, enabling them to upload Standard Usage Scenario scripts and obtain data from the power meter.

The related issue to this project : https://invent.kde.org/teams/eco/sustainable-software-goal/-/issues/3

Expected results: Developers can upload Standard Usage Scenario scripts and obtain data from the power meter remotely.

Knowledge Prerequisite: React/Django(Any web framework), Networking/Knowledge of tunneling, Task scheduling and Energy Measurement process.

Duration: 175 hours

Mentor: Joseph P. De Veaugh-Geiss (@joseph:kde.org ), Volker Krause(@vkrause:kde.org)

• digiKam project web site
• Mailinglist
• digikam Documentation

Project: Improve Items Properties Management

Brief Explanation: the goal of this project is to improve the Items properties management. digiKam Properties (as Tags, Color Labels, Rating, Pick Labels, etc.) and Metadata entries (as Exif, Iptc, and Xmp tags) must be copiable between one item to other ones. Drag and drop and clipboard key features must be supported to make these operations. For the copiable Metadata entries, a preferred list of tags must be configurable to simplify workflow users.

Expected Results:

Provide new options to copy digiKam properties or metadata entries between items. Write unit-tests, and documentation.

Bugzilla Entries:

• Allow to apply the previously assigned tag to a new image
• Easily copy properties from one image to another one

Duration: 175 hours

Knowledge Prerequisite:

• C++, Qt API, GUI, CMake, metadata, database

Mentors: Thanh Trung Dinh ([email protected]), Maik Qualmann ([email protected]), and Gilles Caulier ([email protected])

Project: Add Automatic Tags Assignment

Brief Explanation: the goal of this project is to assign automatically a tags to items by contents analysis using deep learning. Places, Animals, Plants, Scene Type, Events, etx, must be recognized and corresponding keywords must be generated to be be stored in database and assigned to items. This kind of feature must be available as Maintenance tool, Batch Queue Manager tool, or from Captions sidebar.

Expected Results:

Provide new tool for auto assignment of Tags to items. Write unit-tests, and documentation.

Bugzilla Entries:

• Detecting black & white image
• Objects / Forms / Monuments / Context detection and recognition using Deep Learning

Duration: 175 hours

Knowledge Prerequisite:

• C++, Depp Learning, OpenCV, Qt API, GUI, CMake, metadata, database

Mentors: Thanh Trung Dinh ([email protected]), Maik Qualmann ([email protected]), and Gilles Caulier ([email protected])

Your Own Idea

Project: Something that you're totally excited about

Brief explanation: Do you have an awesome idea you want to work on with KDE but that is not among the ideas below? That's cool. We love that! But please do us a favor: Get in touch with a mentor early on and make sure your project is realistic and within the scope of KDE. That will spare you and us a lot of frustration.

Expected results: Something you and KDE loves

Knowledge Prerequisite: Probably C++ and Qt but depends on your project

Duration: Mention one of ~175 or ~350 hours of effort necessary to finish the project. Use only one of these two project classes and don't come up with other numbers here.

Mentor: Try to see who in KDE is interested in what you want to work on and approach them. If you are unsure you can always ask in #kde-soc:kde.org on matrix.
