The Zeta potential calculation tools are a C++ library, a command line tool, and a Windows GUI for calculating zeta potentials for ka > 6 from electrophoretic mobilities measured at the stationary level or from apparent zeta potentials displayed by zetameter (estimated by the Smoluchowski equation). Apparent mobilities are measured at 3 different levels in a rectangular electrophoretic cell (aspect ratio > 4), and can be used to calculate the zeta potential using the parabola method.
Set-cd-rom-speed is an application for setting CD-ROM and DVD-ROM drive speed, written with KDE Kommander. Fast CD-ROM and DVD-ROM drives have one big disadvantage over older and slower models in that they are often quite loud because of the disk spinning very fast in the drive. Using set-cd-rom-speed, you can decrease the drive's speed and thus reduce the annoying noise.
Cryproc is module for the Linux 2.6 kernel that allows user space programs to access the kernel's cryptographic functions. When loaded, the module creates a file called "cryproc" in the /proc filesystem. Applications can open this file read-write and instruct the kernel to perform some of the functions the CryptoAPI provides. A sample application, cryproc-tool, is provided.
