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.
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.
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.
Libntoh aims to be a user-friendly library to provide an easy way to perform defragmentation and reassembly of network/transport protocols. It is intended to provide a flexible, thread-safe, and highly configurable environment for the user. It performs IP defragmentation and TCP reassembly.
BS is a data structures library. It features fixed size, random access sequences. The sequences are constructed over B-trees. Complexity for most single item operations is about O(logN). The sequences are three to five times faster over random access BST-based sequences, while having better memory usage characteristics.
