libjmmcg is a basic, low-level library with pretensions to implementing features above and beyond (but not necessarily better than!) those implemented within the Standard C++ Library and the Boost Library. It features a library for multi-core or multi-chip SMP parallelism, a suite of hashing algorithms, functions for raising numbers to integer powers, a generic factory wrapper and a generic, multi-threaded, read-only cache (which uses PPD), arguably the world's worst sorting technique, trace output, exceptions that have the file, line, revision, function, and argument details, string utilities, logging, simple command line processing, and much more.
Government Sanctioned is a custom-developed text-based RPG (i.e., MUD). New players enter the world of Government Sanctioned as covert agents working for a super-secretive government organization colloquially known as "the agency". Players have a choice of six different roles spanning 19 unique professions. Whether you like stealthy, clandestine operations, the use of subterfuge and guile to infiltrate enemy organizations, or full-blown military actions, the agency has a spot for you. Players are empowered to deeply customize their character through numerous differentiation mechanisms. Character backgrounds lay the foundation for character abilities and are further defined through their cover occupation and agency department affiliation. To put a fine point on character customization, the skill and feat system provides an extensive array of options to tweak the character to suit your style of game play. The skill system boasts over 35 different skill families with around 50 different skills and checks. Skill points are gained upon professional level advancement and can be spent any way the player chooses. With 19 feat trees and over a hundred diverse feats (with new feats being added regularly), your capability for customization is endless.
libktomgirl is a library that reads a subset of the Tomboy file format. When it's done, it should support reading and writing all aspects of files created by Tomboy, Gnote, and KTomGirl. Despite the K in its name, there are no KDE or Qt dependencies (nor C#, GKT, or GLIB). This is pure C++ with boost and stdlib only. Most of the code is from Gnote.
LIME is a dynamic programming language with a LISP-like syntax. It features partial function application, eager and lazy evaluation, call-by-value and call-by-reference, macros, reading/writing LIME code as data, a standard library including infinite streams, and an interactive mode with auto-indentation.
Galera wsrep provider is a dlopenable generic replication library which implements the wsrep provider API. It provides very efficient synchronous replication, and multi-master and "parallel applying" capabilities for opaque data buffers. Its primary focus is data consistency. A transaction is either applied on every node, or not at all. It works anywhere TCP works, including on WAN, and can utilize UDP multicast where available. It is used by the MySQL-wsrep patch project to create true multi-master MySQL/InnoDB clusters.
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.
