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.
Qore PostgreSQL Module is a DBI driver module for the Qore programming language to communicate with PostgreSQL databases. The PostgreSQL driver transparently handles client and server character encodings, supports multi-threading, transaction management, stored procedure execution, and more.
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.
DromeAudio is a small audio manipulation and playback library. It features a simple API for loading, generating, processing, and playing audio. Some of its features include loading and saving WAV sounds, loading Ogg Vorbis sounds, audio mixing/playback, and dynamic audio processing effects such as pitch shifting and echo.
Post Scriptum is a programming language for preparing PostScript documents and programs. The language is procedural, and uses classical control structures (functions, loops, and conditional statements) and commonly known data types (numbers, arrays, strings, and dictionaries). Its syntax is simple, clear, and easy to learn. The compiler translates programs written in Post Scriptum directly to a PostScript file, which can be than executed by a PostScript interpreter (such as Ghostscript), printed, or used as a procset, driver, or library.
