The stx::CBTreeDB is a collection of C++ classes with which read-only key-value database files can be created and read. A database efficiently maps a large number of integral fixed-length keys to opaque binary value blobs. Variable-length or duplicate keys are currently not supported. Keys are organized into a highly compact index structure, which is very similar to a B-tree and allows very fast key lookups. Both keys and values are stored in order and thus queries in a local proximity can benefit from caching effects. All applications mapping a large number of constant, integral keys to string or data blobs can benefit from this library.
JCGO (pronounced as "j-c-go") translates (converts) programs written in Java into platform-independent C code that can be compiled (by third-party tools) into highly-optimized native code for the target platform. JCGO is a powerful solution that enables your desktop, server-side, embedded, mobile, and wireless Java applications to take full advantage of the underlying hardware. In addition, JCGO makes your programs, when compiled to native code, as hard to reverse engineer as if they were written in C/C++. The JCGO translator uses some optimization algorithms that allow, together with optimizations performed by a C compiler, the resulting executable code to reach better performance compared with the traditional Java implementations (based on the Just-In-Time technology). The produced executable does not contain nor require a Java Virtual Machine to execute, so its resource requirements are smaller than that required by a typical Java VM. This also simplifies the process of deployment and distribution of an application.
PICI-NMS is an object oriented middleware which makes possible sending messages in a networked environment or on a single host between applications using the library provided. The supported message sending mechanism is "publish/subscribe" and this is backed up by a very easy-to-use and intuitive C++ API which hides the underlying socket interface to make the message sending as transparent to the client as possible.
LMDBG is a collection of small tools for collecting and analyzing the logs of malloc/realloc/memalign/free function calls. Unlike many others, LMDBG does not provide any way to detect overruns of the boundaries of malloc() memory allocations, as this is not the goal. Like most other malloc debuggers, LMDBG allows detecting memory leaks and double frees. However, unlike others, LMDBG generates full stacktraces and separates the logging process from analysis, thus allowing you to analyze an application on a per-module basis.
Minnow is a concurrent programming language with a Ruby-like syntax. It compiles to an executable and uses a companion library to allow fully-rebalanced microthreads. Minnow gains a lot of strength from its actor model, which uses message passing, as opposed to threads and locking, as its concurrency model. Taking a cue from Erlang, actor creation and message passing is extremely lightweight (often on the order of a few nanoseconds). The language has a built-in foreign function interface that allows developers to leverage existing C-based libraries in a simple SWIG-like manner. Minnow's object model is based on "melding" features together to form objects.
Linux, FreeBSD, and Mac OS X all provide similar extended file attributes functionality, with significantly different interfaces. The pxattr package aims at providing a single extended file attributes interface on all three systems (and others in the future). It consists of a single C++ module to be included in the application source code. The C++ file can also be compiled to a command line attributes management command and test tool.
libpwstor is a library implementing a password storage format for C programmers. This format provides a reasonable level of security by utilizing SHA-256 in addition to a random salt to mitigate dictionary and rainbow table attacks. In addition to the core functionality, libpwstor also offers some additional functions such as Base64 encoding and decoding. All functionality is implemented and designed in such a way as to be easy to use for C programmers of varying skill levels, while preserving reasonable security in the underlying storage format.
libmsocket is a socket abstraction library in C, which aims to support as many protocol abstractions transparently as possible. Current goals include SSL and Socks5 proxies. At its core, libmsocket makes developing socket applications very easy, even if you're not using any of those abstractions at all. It also ties in to libevent for I/O multiplexing and asynchronous DNS resolution.
