For users on Linux and Unix, KDE offers a full suite of user workspace applications which allow interaction with these operating systems in a modern, graphical user interface. This includes Plasma Desktop, KDE's innovative and powerful desktop interface. Other workspace applications are included to aid with system configuration, running programs, or interacting with hardware devices. While the fully integrated KDE Workspaces are only available on Linux and Unix, some of these features are available on other platforms. In addition to the workspace, KDE produces a number of key applications such as the Konqueror Web browser, Dolphin file manager, and Kontact, the comprehensive personal information management suite. The list of applications includes many others, including those for education, multimedia, office productivity, networking, games, and much more. Most applications are available on all platforms supported by the KDE Development. KDE also brings to the forefront many innovations for application developers. An entire infrastructure has been designed and implemented to help programmers create robust and comprehensive applications in the most efficient manner, eliminating the complexity and tediousness of creating highly functional applications.
Calligra is an integrated suite of applications that cover office, creative, and management needs. It offers applications on both desktop computers and mobile platforms like tablets and smartphones. OpenDocument Format (ODF) is used, making it compatible with OpenOffice.org, LibreOffice, and Microsoft Office. Calligra Suite contains the following applications: Calligra Words (word processor), Sheets (spreadsheets), Stage (presentations), Flow (diagrams and flowcharts), Kexi (visual database creator), Braindump (note taking), Plan (project management), Krita (drawing), and Karbon (vector graphics).
Chakra Linux is a Linux distribution that combines the simplicity of Arch Linux with KDE. It is fast, user-friendly, and extremely powerful. It can be used as a live CD or installed to hard disk. Chakra is currently under heavy and active development. It features a graphical installer and automatic hardware configuration. Chakra provides a modular and tweaked package set of the KDE Software Compilation with a lot of useful additions. It features the concept of half-rolling releases and freshly cooked packages and bundles. It is designed for people who really want to learn something about Linux or don't want to deal with administrative overhead.
Marble is a Virtual Globe and World Atlas that you can use to learn more about Earth: you can pan and zoom around, and you can look up places and roads. A mouse click on a place label will provide the respective Wikipedia article. It's also possible to measure distances between locations or watch the current cloud cover. Marble offers different thematic maps: a classroom-style topographic map, a satellite view, street map, earth at night, and temperature and precipitation maps. All maps include a custom map key, so it can also be used as an educational tool for use in classrooms. For educational purposes, you can also change the date and time and watch how the starry sky and the twilight zone on the map change. Marble also features multiple projections: choose between a flat map ("Plate carré"), Mercator, or the globe.
Music Manager is a Konqueror plugin that lets you standardize the filenames of your music files, guess information and set ID3 tags from the file's name (this can be done to several files in one shot), rename many selected files based on their ID3 tags, set ID3 tags in mass for selected files with options for copying ID3s from other files and leaving some ID3 fields untouched, rename _ to space and vice versa, create HTML and text indexes of your collections (including total playing time, etc., configurable through templates), create nice CD covers with full listings of your music files (also configurable through templates), and organize your music collection to create a CD.
KDE Plasma Active is a user interface for all types of tablets, smartphones, and touch computing devices, such as settop boxes, smart TVs, home automation, and in-vehicle infotainment. It is a joint project by the KDE community, basysKom, and open-slx. Its goals are a fast embedded UX platform with minimal memory requirements, customizable and modular to support different form factors, and an interface which adapts as users change activities.
Fract-O-Rama is a Qt-based fractal generation program. All fractal images are specified using the program's fractal scripting language, so it is possible to explore a wider variety of fractal types/options than with many other generation programs. Full source is included, and the program readily compiles/runs on UNIX or win32 (win32 binaries are also available, as a Qt commercial license is required to build the program on windows). It comes with documentation and many example fractals.
The Gluon project is an open framework for creating and distributing games, supporting the flow of the idea all the way from the author to the player of the finished game. The current goal for the first stable release is to create games using 2D graphics. The reasoning behind this is that the niche for this type of visual is very large and so far untapped by specialized tools. In the world of 3D games there are solutions such as Unity3D, which provide a distribution system, but in the 2D game development world there are no tools to provide a complete ecosystem for creation, distribution, and feedback gathering. The three main audiences of Gluon are game creators, game players, and application programmers. Each of these are a user of one of the tools.
Strigi is a desktop and indexer independent desktop search engine. Its main features include very fast crawling, a very small memory footprint, no hammering of the system, and pluggable backends (currently clucene and hyperestraier was provided). Communication between the daemon and search program is done over an abstract interface which is desktop independent. A small Perl program with an example of how to query the database is included along with an example KDE client application and a KIO interface.
