libstream is a fast I/O stream library written in C. It supports common stringstream operations such as read(), write(), and peak(). Instead of using one large buffer, libstream splits its internal buffer into a linked list of fixed-size chunks, thus featuring a more efficient memory footprint. There are no external dependencies.
tcpdump prints a description of the contents of packets on a network interface which match a given boolean expression. It can also be run with the -w flag, which causes it to save the packet data to a file for later analysis, and/or with the -r flag, which causes it to read from a saved packet file rather than to read packets from a network interface. In all cases, only packets which match the expression will be processed by tcpdump. tcpdump logs more than just TCP, IP, or ethernet packets, but has a whole suite of decoders, including ones for USB.
Metacza is a language and its compiler which produces output in the C++ Meta Template Language. Its concise syntax makes Meta Template Programming much easier. Metacza allows you to write programs using boost::mpl, and to produce C++ header files that can be used on their own. Programming without boost::mpl is also supported. Metacza is a higher order language with closures, let, and lambda.
Lziprecover is a data recovery tool and decompressor for files in the lzip compressed data format (.lz) able to repair slightly damaged files, recover badly damaged files from two or more copies, extract undamaged members from multi-member files, decompress files, test integrity of files, extract a range of bytes from a file, and list the correct size of multi-member files. Lziprecover is able to recover or decompress files produced by any of the compressors in the lzip family; lzip, plzip, minilzip/lzlib, clzip, and pdlzip. This recovery capability contributes to make the lzip format one of the best options for long-term data archiving.
Speedpad is a small and portable ncurses-powered tool to test, train, and increase typing speed on arbitrary text input. It is designed for intermediate-to-advanced level typists and assumes that you have already learned how to touch type. It does not use lessons, single words, or other synthetic stuff. It supports tab expansion, auto indentation, and syntax to train on code. It features a reference speed robot and supports CPS, CPM, WPM, PPM, and CPH/KPH metrics. It shows detailed statistics about speed and helps find and eliminate frequent typos. Stats are dumped to standard output in a machine-readable format after completion, and can be piped into gnuplot.
