MUSCLE (Multi User Server Client Linking Environment) is an N-way messaging server and networking API. It includes client-side networking APIs for various languages, including C, C++, C#, Delphi, Java, and Python. MUSCLE lets programs communicate over a network via streams of serialized Message objects. The included server program ("muscled") lets its clients message each other and store information in its server-side hierarchical database. The database supports flexible queries via hierarchical wildcarding, and "live" updates via a subscription mechanism.
Python bsddb3 is a Python module that provides a nearly complete wrapping of the Oracle/Sleepycat C API for the database environment, database, cursor, sequence, and transaction objects, and each of these is exposed as a Python type in the bsddb3.db module. The database objects can use various access methods: btree, hash, recno, and queue. It has complete support for Berkeley DB distributed transactions, and complete support for the Berkeley DB Replication Manager and base replication API. The goal is to mirror most of the real Berkeley DB API.
arraymanip is a PHP class for manipulating data in arrays. It is capable of moving elements from one position to another, deleting elements, and inserting elements in specific positions. It supports mixed indexed arrays, although this isn't recommended. By default it works with integer indexed arrays.
NetCrypto is a library of functions and a framework to interface with crypto algorithms provided by the calling application, built-in, or provided through shared libraries. It was developed with some features from OpenSSL in mind and with some inspiration from OpenSSL's EVP layer and ENGINE framework.
The Better String Library is an abstraction of a string data type which is superior to the C library char buffer string type and C++'s std::string. Among the features achieved are substantial mitigation of buffer overflow/overrun problems and other failures that result from erroneous usage of the common C string library functions, significantly simplified string manipulation, high performance interoperability with other libraries that expect '\0' terminated buffers, high performance common string operations, and functional equivalency with other more modern languages.
MyActiveRecord is a PHP implementation of Martin Fowler's Active Record pattern, as popularised by Ruby on Rails. Objects are retrieved via static methods of the base class, resulting in clean and simple relational/object mapping. It's MySQL only, meaning the whole thing is contained within a single class and none of the overhead of database abstraction is incurred. There is close to zero configuration. Even relationships are inferred, although this does mean sticking to some simple database naming rules.
