Sman is "The Searcher for Man Pages", an enhanced version of "apropos" and "man -k". Sman adds several key abilities over its predecessors, including stemming and support for complex boolean text searches such as "(linux and kernel) or (mach and microkernel)". It shows results in a ranked order, optionally with a summary of the manpage with the searched text highlighted. Searches may be applied to the manpage section, title, body, or filename. The complete contents of the man page are indexed. A prebuilt index is used to perform fast searches.
libphidgets is a user-space access library for the Phidget devices. It provides a generic and flexible way to access and interact with the Phidgets, and comes with all the advantages of a user-space library. It is based on libhid (which is based on libusb), thus it requires no HID support in the kernel. Furthermore, it aims to support all operating system supported by libusb/libhid: Linux, BSD, OS X, and Windows.
Deduplicator is a simple and efficient data deduplicator that works by hard linking files that have the same content. It is ideal for reducing the size of backups. It can save and restore intermediate results, so you can run it in a few short intervals, and allows you to review changes before they are committed to disk.
