AVL Array is an STL-like container for C++ that fills the gap between vector (or deque) and list, providing both fast random access and fast insertion/removal, all O(log n). This is not a map; in an avl_array, the "keys" always range from 0 to size-1, and they automatically change on insertion or removal. As a sequence container, like vector and list, it respects the order of elements.
BitMagic is C++ library designed and developed to implement efficient, platform-independent bitsets. It features several types of on-the-fly adaptive compression, dynamic range of addressable space of 2^32-1 bits, efficient memory management, serialization in a platform-independent, compact format suitable for storing in files and databases, performance tuning for 32-bit and 64-bit systems, and optimization for Intel SSE2 128-bit integer SIMD.
The Machine Objects class library allows the creation of state machines based on the "State" design pattern in straight C++. It extends the pattern with the option to create hierarchical state machines, making it possible to convert the popular UML statechart notation to working code in a straightforward way. Other features are entry and exit actions, state histories, and state variables.
C++ Resources Compiler is a tool that will generate a C++ source file (along with the corresponding header file) that embeds any given data file and provides a Resource class which gives access to this data. The Resource class can be created in two flavors: one using STL streams, the other using WxWidgets streams. Its function is similar to that of the "qtrc" tool from the Qt toolkit.
Chakra Linux is a Linux distribution that combines the simplicity of Arch Linux with KDE. It is fast, user-friendly, and extremely powerful. It can be used as a live CD or installed to hard disk. Chakra is currently under heavy and active development. It features a graphical installer and automatic hardware configuration. Chakra provides a modular and tweaked package set of the KDE Software Compilation with a lot of useful additions. It features the concept of half-rolling releases and freshly cooked packages and bundles. It is designed for people who really want to learn something about Linux or don't want to deal with administrative overhead.
