SDL_net library is a small sample cross-platform networking library, with a sample chat client and server application. The chat client uses the GUIlib GUI framework library.

Simple DirectMedia Layer is a cross-platform multimedia library designed to provide low level access to audio, keyboard, mouse, joystick, 3D hardware via OpenGL, and 2D video framebuffer. It is used by MPEG playback software, emulators, and many popular games, including the award winning Linux port of "Civilization: Call To Power."

Simple DirectMedia Layer supports Linux, Windows, BeOS, MacOS Classic, MacOS X, FreeBSD, OpenBSD, BSD/OS, Solaris, IRIX, and QNX. There is also code, but no official support, for Windows CE, AmigaOS, Dreamcast, Atari, NetBSD, AIX, OSF/Tru64, RISC OS, and SymbianOS.

SDL is written in C, but works with C++ natively, and has bindings to several other languages, including Ada, Eiffel, Java, Lua, ML, Perl, PHP, Pike, Python, and Ruby.

OSSP sa is an abstraction library for the Unix socket application programming interface (API) featuring stream and datagram oriented communication over Unix Domain and Internet Domain (TCP and UDP) sockets.
It provides the following key features: address abstraction (local, IPv4, and IPv6), type abstraction, I/O timeouts, I/O stream buffering and convenience I/O functions.
Main features:
Stand-Alone, Self-Contained, Embeddable
- Although there are various Open Source libraries available which provide a similar abstraction approach, they all either lack important features or unfortunately depend on other companion libraries. OSSP sa fills this gap by providing all important features (see following points) as a stand-alone and fully self-contained library. This way OSSP sa can be trivially embedded as a sub-library into other libraries. It especially provides additional support for namespace-safe embedding of its API in order to avoid symbol conflicts.
Address Abstraction
- Most of the ugliness in the Unix Socket API is the necessity to have to deal with the various address structures (struct sockaddr_xx) which exist because of both the different communication types and addressing schemes. OSSP sa fully hides this by providing an abstract and opaque address type (sa_addr_t) together with utility functions which allow one to convert from the traditional struct sockaddr or URI specification to the sa_addr_t and vice versa without having to deal with special cases related to the underlying particular struct sockaddr_xx. OSSP sa support Unix Domain and both IPv4 and IPv6 Internet Domain addressing.
Type Abstraction
- Some other subtle details in the Unix Socket API make the life hard in practice: socklen_t and ssize_t. These two types originally were (and on some platforms still are) plain integers or unsigned integers while POSIX later introduced own types for them (and even revised these types after some time again). This is nasty, because for 100% type-correct API usage (especially important on 64-bit machines where pointers to different integer types make trouble), every application has to check whether the newer types exists, and if not provide own definitions which map to the still actually used integer type on the underlying platform. OSSP sa hides most of this in its API and for socklen_t provides a backward-compatibility definition. Instead of ssize_t it can use size_t because OSSP sa does not use traditional Unix return code semantics.
I/O Timeouts
- Each I/O function in OSSP sa is aware of timeouts (set by sa_timeout(3)), i.e., all I/O operations return SA_ERR_TMT if the timeout expired before the I/O operation was able to succeed. This allows one to easily program less-blocking network services. OSSP sa internally implements these timeouts either through the SO_{SND,RCV}TIMEO feature on more modern Socket implementations or through traditional select(2). This way high performance is achieved on modern platforms while the full functionality still is available on older platforms.
I/O Stream Buffering
- If OSSP sa is used for stream communication, internally all I/O operations can be performed through input and/or output buffers (set by sa_buffer(3)) for achieving higher I/O performance by doing I/O operations on larger aggregated messages and with less required system calls. Additionally if OSSP sa is used for stream communication, for convenience reasons line-oriented reading (sa_readln(3)) and formatted writing (see sa_writef(3)) is provided, modelled after STDIOs fgets(3) and fprintf(3). Both features fully leverage from the I/O buffering.
Enhancements:
- Removed SA_SYSCALL_GETHOSTBYNAME because gethostbyname(3) cannot be overridden as at is use point (function sa_addr_u2a) the sa_t object is not available.
- Additionally, for IPv6 getaddrinfo(3) would have been overridden, too.
- This fixed compilation on platforms without IPv6 APIs.

The BigFish Firewall is a suite PHP scripts that generates a firewall script for iptables based firewalls. The script is created following the configuration rules entered by the user or standard pre-configuration rules and protections for linux systems.

Quick Spam Filter (QSF) is an Open Source email classification filter. Quick Spam Filter is designed to be small, fast, and accurate, which works to classify incoming email as either spam or non-spam.

To recognise spam, QSF strips the text out of the email (using MIME decoding and HTML stripping) and then splits it into tokens (words, word pairs, URLs, and so on). These tokens are then looked up in a database and analysed using the Bayesian technique to see whether the email should be classified as spam or not.

The database is generated by a process of training - QSF is given two mailboxes, one containing known spam, and the other containing known non-spam, to train itself on. After training, if QSF misfiles any email, the message it got wrong can be fed back into the database, thus making QSF learn from its mistakes.

For a more in-depth look at the way in which QSF tokenises and classifies messages, please see the Technical Details section of the manual.

QSF is designed to be run by an MDA, such as procmail.

Scala is a modern multi-paradigm programming language designed to express common programming patterns in a concise, elegant, and type-safe way.
Scala smoothly integrates features of object-oriented and functional languages including mixins, algebraic datatypes with pattern matching, genericity, and more.
It is well integrated with Java and .NET: the Scala compiler produces standard Java class files or .NET assemblies, and Java/.NET libraries and frameworks can be used without glue code or additional declarations.
Scala is a pure object-oriented language in the sense that every value is an object. Types and behavior of objects are described by classes and traits. Class abstractions are extended by subclassing and a flexible mixin-based composition mechanism as a clean replacement for multiple inheritance.
Whats New in 2.6.0 RC1 Development Release:
- This version introduces some language changes (existential types, lazy values, structural types, etc.) and fixes many bugs.
