Parley

Vocabulary Test

Area: Documentation
Description: Prepare for a vocabulary test with Parley. While doing that, write an introduction with screen-shots how you used and configured the program. With your tutorial it should be easy to get up and running to use Parley for those knowledge based tests.
Outcome: A tutorial with screen-shots that explains one use case for Parley.
Difficulty: easy

Spell-checking improvements

Area: Code
Description: There is a basic implementation for spell-checking in Parley. It is in a very rough state and prone to crashes. Improving the language selection and making it possible to check the spelling in one language at a time will make this feature much more useful.
Outcome: Spell-checking per language is possible, better language selection.
Difficulty: hard, at least basic C++ knowledge required
Time: 2 weeks (1 week to get Parley compiled, 1 week to change the code)

QML plasmoid

Area: Code
Decription: with the KDE Plasma Workspace 4.6 there is the new possibility to write plasmoids in QML and Javascript, let's try to rewrite one of the standard plasmoids in this language
Outcome: a simple plasmoid of the default set reimplemented almost identic in QML (suggested: RSSnow) this will kickstart the migration towards QtComponents and scene graph Difficulty: easy

KDE and the Masters of the Universe

News Anchor

Area: Outreach
Description: Collect, write and record a small news segment for KDEMU; News must relevant to KDE and/or the Free desktop scene. Non-KDE related content must be in some way relevant to the KDE community (like Linux or X.org news).

Difficulty: Medium
Time: 4 week

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
IRC: #koffice on freenode
Mailing List: koffice-devel at kde org
Mentor: Marijn Kruisselbrink ([email protected])

Krita

Implement GIMP's VBR Brush support

Area: Code
Description: VBR Brush file format is used by GIMP for storing parametric brushes. They are used by digital artists. It is simple text file. Your task is to implement loading of this brush format as preset for the brush engine Pixel Brush, which is equivalent to the brush engine in GIMP.
Outcome: Happy artists, better interoperability with GIMP
Difficulty: medium
Time: few days
