Khayyam is a program for composing 3D scenes for rendering (similar to Poser and DAZ Studio). It can import character and scene models from many model formats (Poser, MD5, BSP, OBJ, 3DS, Collada, and formats used in most Illusion games). There is support for basic object placement, scaling, posing skeletal characters, and lighting. Scenes can be exported in POV-Ray format for rendering. Khayyam is implemented as a shell program using many libraries from the Floyd and Sodipodi projects.
KiCad EDA is software for the creation of electronic schematic diagrams and printed circuit board artwork. It is a set of four programs and a project manager: Eeschema (schematic entry), Pcbnew (a board editor), Gerbview (a Gerber viewer (photoplotter documents)), and Cvpcb (a footprint selector for components used in the circuit design). Kicad is the project manager. It includes a 3D visualization feature.
Kid3 tagger can edit the ID3v1 tags and all ID3v2 frames in MP3 files and the tags in Ogg/Vorbis and FLAC files in an efficient way. It is easy to convert between ID3v1 and ID3v2, set the tags of multiple files to the same values and generate the tags from the file name or vice versa. Import is possible from freedb.org, MusicBrainz, and other sources of track data.
KildClient is a MUD client written with the GTK+ windowing toolkit. It supports many common features of other clients, such as triggers, gags, aliases, macros, timers, and much more. But its main feature is the built-in Perl interpreter. At any moment, the user can execute Perl statements and functions to do things much more powerful than simply sending text the the MUD. Perl statements can also be run, for example, as the action of a trigger, allowing you to do complex things.
Kimai is software that tracks work time and classifies it. It tracks time and prints out a summary (time sheet) of your activities on demand. The reports can be yearly, monthly, daily, by customer, by project, or by action. Its interface is based on using a Web browser. You can install it as a Web service or as a single-user program on your local workstation. It is appropriate both for multiple simultaneous users or a single user. Kimai does not have to run to do the recording.
KinderGate Parental Control features content filtering based on morphological analysis, a vast URL database divided into 70+ categories, download control, safe search, HTTPS support, and more. It provides high accuracy Web filtering with an extremely low false detection rate. It blocks resources related to malware, porn, drugs, abusive content, illegal materials, and other categories. It is widely used by schools, libraries, and home users.
Kinonk is a Pentominoes program written in C++. Pentominoes is a two-player board game where the goal is to be the last player to put a pentomino (a piece composed of five squares) on the board. Kinonk can also play Katamino, a variant of pentominoes. It uses a simple brute force algorithm, and can play any position perfectly if given enough time. You can constrain its time by giving an arbitrary time limit, or simply let it analyze everything. Charts can be generated using a Perl script included in the package.
