ISP-fW is a firewall script which provides port forwarding, packet filtering, stateful packet inspection, port redirection, masquerading, SNAT/ DNAT, TOS, and generation of htb rules for bandwidth management. It includes a Web interface for easy access. It's useful for ISPs which want to separate National traffic from International traffic.
Siren Renamer is a tool that renames, moves, and copies files using an expression. A lot of information associated with a file can be used, including name, extension, dates, and selection number. Other information is extracted from files according to their type: audio, video, image (standard and raw), EXIF, IPTC, Office document, PDF, ePub, HTML, and many others. Many different operations can be performed on character strings, complete directory trees can be processed, and images can be viewed. For example, to change a file name to uppercase with the mp3 extension, the expression can be '%ub.mp3'.
FeatureC++ is a C++ language extension that supports Feature-Oriented Programming (FOP). FOP studies feature modularity in program families. The idea of FOP is to build software by composing features. Features are basic building blocks that satisfy intuitive user-formulated requirements on the software system. Features refine other features incrementally. This step-wise refinement leads to a layered stack of features. Mixin Layers are one appropriate technique for implementing features.
GenFoo is a general Fokker-Planck solver for models of arbitrary dimensionality. It contains three backend solvers, a delta-f Monte Carlo, a standard Monte Carlo, and a Finite Element solver. The key property of the GenFoo package is that physics are separated from numerics by runtime loading of the Fokker-Planck coefficients, which enable solutions of a large class of Fokker-Planck models.
yacts, yet another continuous time simulator, uses J+ to interpret scripts, defining systems of ordinary differential equations, which it solves. J+ is a functional non-imperative simulation language with lazy evaluation, based on the J programming language, a dialect of APL. A program in J+ is a collection of (possibly functional) J assignment statements, just like a set of formulae on a sheet of paper. The interpreter, implemented as a software library, knows the interdependencies between these formulae and is able to compute any of the defined quantities with minimal effort, keeping track of the values which were already computed. The driver program (such as yacts) may ask the interpreter to compute certain quantities and set the values for others (propagating the changes to dependents).
