KStars

KStars is an application that aims to be the all-in-one astronomy portal. It draws a map of the sky, does some cool calculations, helps manage your observations amongst other things! Help us take it even further!

Document the Observation Planner

Area: Documentation
Description: Write clear documentation on all currently implemented functionalities of the Observation Planner in KStars. The help is essentially outdated, and this task aims to update it. This will involve learning a really simple schema called Docbook, which you can learn by looking at other help files. The next thing you would do is to explain how to use the Observation Planner tool and explain what each feature does, with appropriate screenshots. Will be a good task to pick if you are an amateur astronomer.
Outcome: A nice help / user guide for the Observation Planner.

Documentation on Types of Telescopes

Area: Documentation
Description: As a part of KStars, there was a project called AstroInfo that was started several years ago. The aim of the project is to provide an encyclopedia of information accessible from within KStars, with stuff that you can try from within KStars to enhance your understanding! This content is not supposed to be as in-depth as a full-fledged encyclopedia like Wikipedia, but at a much more accessible level. The aim of this project is to write a few articles about Telescopes. It should include these topics: Types of telescopes, Parameters used to describe telescopes (aperture, focal length) etc, Image quality and Aberrations, Calculation of magnification / Field-of-view. There should also be examples of how to use KStars to calculate the FOV of a telescope. A great task to pick if you are planning to do something physics / astronomy related in future.
Also note that you should write all text on your own and not just copy-paste from other sources. Copy-pasting from other sources without appropriate attribution, called plagiarism, is a crime. Copy-pasting might not be allowed (even with attribution) by some sources, depending on their licensing terms. So you should write things on your own.
Outcome: Information about telescopes as part of the AstroInfo project.
Difficulty: easy
Time: 1 week ~ 1.5 weeks

Links that explain terms within menus

Area: Code
Description: Astronomy can have a lot of technical terms, and these can make astronomy in general, and KStars, inaccessible to a beginner. The aim of this project is to connect up to the documentation in the AstroInfo project (read about AstroInfo in the previous task description) from various menus in KStars. Wherever there is a technical term in KStars (eg: RA / Dec / Airmass etc in the Details Dialog, Catalog numbers / magnitude / constellation name in the context menu when clicking on an object), there should be a clickable link that takes the user to the corresponding page from the Astroinfo project.
To do this project, you should know basic C++ and should be able to learn to use a couple of Qt-specific things pretty fast.
TODO: Add more detail.
Outcome: Links to information near technical terms in KStars

KOffice

KSpread

Implement byte-position text functions as aliases for the normal text functions

Area: Code
Description: The OpenDocument specification, which specifies formulas that should be supported by spreadsheet applications, defines a number of so-called byte-position text functions. These functions are currently not supported in kspread, and adding support for them is rather easy as they can just be aliases for the character-position text functions (these functions are FINDB, LEFTB, LENB, MIDB, REPLACEB, RIGHTB and SEARCHB).
Outcome: Support for the byte-position text functions, by adding them as alias to the character-position text functions.
Difficulty: easy
Time: 1-2 days
IRC: #koffice on freenode
Mailing List: koffice-devel at kde org
Mentor: Marijn Kruisselbrink ([email protected])

Add support for the PERMUTATIONA function to kspread

Area: Code
Description: Among the spreadsheet functions that are currently not supported by KSpread but are defined in the OpenDocument specification (which kspread aims to fully implement at some point), is the PERMUTATIONA function. PERMUTATIONA is very similar to the currently supported POWER function, it mostly puts some extra constraints on the input values (that should result in an error as output value), so for the implementation the current POWER implementation should be helpfull.
Outcome: Support for the PERMUTATIONA function in kspread
Difficulty: medium
Time: 1 week

Okular

Move KPDF bugs/wishes to Okular

Area: Bug triaging

KDE Community Forums

Area: Code
Description: Just like any other forum, KDE Forums being a popular resource is often a target for spammers (both human and bots). Of course, we cannot do much about the human spammers, but identifying spam bots is quite doable given that we identify the patterns. This project involves interaction with the forum staff and getting to know how the most common spam-bot profiles look. The aim is to develop a PHP script for the forum engine phpBB that would hook itself with user profile updates, track any change and pass them through regexes (say for example, for links in their signature, etc.) and move the user to a special usergroup if found suspicious.
Outcome: Spam-bots get auto moved to a special usergroup that has posting restrictions.

Translation of UserBase pages

Area: Documentation/Translation
Description: Translation of sets of UserBase pages into a language of your choice. The pages should be those most needed by newcomers either to KDE Software or new to contributing to documentation. They are defined on the following pages: http://userbase.kde.org/Category:Getting_Started (with a sub-category Configuration) and http://userbase.kde.org/Category:Contributing. There are 44 pages in all. It is anticipated that on-line translation will be used, at least at first, with the student progressing to off-line translation using gettext and Lokalization should time allow.
Outcome: Useful "own-language" documentation is created and the student learns to be comfortable with translation software.
