Jim is a small footprint implementation of the Tcl programming language. It implements a large subset of Tcl and adds new features like references with garbage collection, closures, a built-in object oriented programming system, functional programming commands, and first class arrays. The interpreter's executable file is only 70 KB in size, and can be reduced by further excluding some commands. It is appropriate for inclusion inside existing programs, for scripting without dependencies, and for embedded systems.
ATF is a collection of libraries and utilities designed to ease unattended application testing in the hands of developers and end users of a specific piece of software. Tests can currently be written in C/C++ or POSIX shell and, contrary to other testing frameworks, ATF tests are installed into the system alongside any other application files. This allows the end user to easily verify that the software behaves correctly on her system. Furthermore, the results of the test suites can be collected into nicely-formatted reports to simplify their visualization and analysis.
Traffic Squeezer is a Linux kernel based WAN network traffic accelerator from Doublefish Solutions. It uses methods such as traffic compression, traffic PDU coalescing, protocol specific acceleration (such as TCP acceleration mechanisms), and quality of service. Traffic Squeezer also contains custom L7filters (application protocol filters), DPI (Deep Packet Engines) and so on to control and administrate your traffic. With Traffic Squeezer, you can optimize MPLS,ISDN, leased links, Satellite Networks, and Marine Internet, and even build your own custom WAN Appliance with Traffic Squeezer. A GUI is now supported via Doublefish Solution Aquarium. Aquarium is a Web-GUI that also supports Traffic Squeezer, Squid, and other open source solutions.
extract_url.pl is a Perl script that extracts URLs from either correctly-encoded MIME email messages or from plain text. It can be used either as a pre-parser for a URL selector (such as urlview), or as a standalone URL selector. It is very configurable, can handle URLs that have been broken over several lines in format=flowed delsp=yes email messages, and eliminates duplicate URLs. It was designed primarily for use with Mutt, but can be used by for any similar purpose. The idea is that if you want to access a URL in an email, you pipe the email to a URL extractor (like this one), which then lets you select a URL to view in some third program (such as Firefox).
Premake is a build configuration tool. Describe your C, C++, or C# software project using a simple, easy to read syntax and let Premake generate the project files for Visual Studio, GNU Make, Xcode, Code::Blocks, CodeLite, SharpDevelop, or MonoDevelop. Premake allows you to manage your project configuration in one place and still support different build systems. It allows you to generate project files for tools that you do not own. It saves the time that would otherwise be spent manually keeping several different toolsets in sync. And it provides an easy upgrade path as new versions of your favorite tools are released.
TooN is a very efficient numerics library for C++. The main focus of the library is efficient and safe handling of large numbers of small vector matrices and providing as much compile time checking as is possible. The library also works with large vectors and matrices and integrates easily with existing code. In addition to elementary vector and matrix operations, the library also providers linear solvers, matrix decompositions, optimization, and wrappers around LAPACK.
DIFFUSE enables FreeBSD's IPFW firewall subsystem to classify IP traffic based on statistical traffic properties. With DIFFUSE, IPFW computes statistics (such as packet lengths or inter-packet time intervals) for observed flows, and uses ML (machine learning) techniques to assign flows into classes. In addition to traditional packet inspection rules, IPFW rules may now also be expressed in terms of traffic statistics or classes identified by ML classification. This can be helpful when direct packet inspection is problematic (perhaps for administrative reasons, or because port numbers do not reliably identify classes of applications). DIFFUSE also enables one instance of IPFW to send flow information and classes to other IPFW instances, which then can act on such traffic (e.g. to prioritize, accept, or deny) according to its class. This allows for distributed architectures, where classification at one location in your network is used to control firewalling or rate-shaping actions at other locations.
