cwfloppy is a Linux device driver for the Catweasel Advanced Floppy Controller manufactured by Individual Computers. The Catweasel is a versatile Shugart bus controller (i.e., it can control floppy drives). It is extremely flexible and can be programmed to read and write just about any floppy disk in the world. This driver supports reading and writing of Amiga and MS-DOS DD/HD 3.5" disks.
SoundTracker is a pattern-oriented music editor (similar to the DOS program 'FastTracker'). Samples are lined up on tracks and patterns which are then arranged to a song. Supported module formats are XM and MOD; the player code is the one from OpenCP. A basic sample recorder and editor is also included.
wgms3d is a full-vectorial electromagnetic waveguide mode solver. It computes the modes of dielectric waveguides at a specified wavelength using a second-order finite-difference method. The waveguide cross section may consist of several adjacent regions of constant refractive index (i.e., step-index profiles). Dielectric interfaces do not have to be aligned with the discretization grid; they may be arbitrarily slanted or curved. The entire waveguide may be curved along the propagation direction. Leakage and curvature losses can be computed using Perfectly Matched Layers as absorbing boundaries.
