Kpl is a KDE program for two- and three-dimensional graphical presentation of data sets and functions (plotter). Multidimensional nonlinear parameter fits of functions to data sets can be performed using the Levenberg-Marquardt algorithm. General linear least square parameter fits are also possible. A D-BUS interface can be used to control Kpl by other applications and scripts.
BitRock InstallBuilder allows you to create easy-to-use multiplatform installers for Linux (x86/PPC/s390/x86_64/Itanium), Windows, Mac OS X, FreeBSD, OpenBSD, Solaris (x86/Sparc), IRIX, AIX, and HP-UX applications. The generated application installers have a native look-and-feel and no external dependencies, and can be run in GUI, text, and unattended modes. In addition to self-contained installers, the installation tool is also able to generate standalone RPM packages.
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.
