Ports Search

This script runs though the complete ports tree without stopping after a make error occurred. If you call make with any parameter in one of the directories of the ports tree in FreeBSD the run will stop if make returns with a code bigger than zero. That means, that it is (in opposite to NetBSD or OpenBSD impossible to run a echo complete build with \"make\" in FreeBSD. Warning: The run of the script may last days (but you may stop it any time). Call the script with the parameter you want to give to make, for instance fetch, build, install, or package. -Andreas Fehlner fehlner@gmx.de

cache-init, cache-update, find-updated and portindex are a set of perl scripts built around the common core of the FreeBSD::Portindex modules. Their use is to generate and maintain the ports INDEX or INDEX-5 files speedily and efficiently. Ultimately they work in a very similar way to the standard make index command, except that the FreeBSD::Portindex tools keep a cache of the make describe output from each port, and can update that cached data incrementally as the ports tree itself is updated.

2d-rewriter is a cellular automata simulator. Key features Declarative input language for rules and initial patterns definition. Ability to emulate Conway's "Life Game" via proper rules specification. Ability to demonstrate self replicating loops. Patterns are tried in 4 orientations. Cell directions are defined against the pattern orientation. Total number of rules can be substantially decreased by using sets and defining patterns using variables. Required run time environment is a minimal X window system installation on a POSIX-compatible system (*BSD/Linux/Mac OS X/Cygwin/...).

Brian is a simulator for spiking neural networks available on almost all platforms. The motivation for this project is that a simulator should not only save the time of processors, but also the time of scientists. Brian is easy to learn and use, highly flexible and easily extensible. The Brian package itself and simulations using it are all written in the Python programming language, which is an easy, concise and highly developed language with many advanced features and development tools, excellent documentation and a large community of users providing support and extension packages.

GRIBEX is an interface for encoding and decoding WMO FM-92 GRIB edition 1 messages and some ancillary subroutines for controlling printing and debugging. The GRIBEX software was developed at the European Centre for Medium-range Weather Forecasts (ECMWF) and is part of the EMOS library. EMOS is mostly written in Fortran. Therefore it has only a Fortran interface. CGRIBEX is a lightweight version of GRIBEX written in ANSI C with a portable Fortran interface. For best compatibility some of the C sources were converted from the Fortran GRIBEX version.

FastCap computes self and mutual capacitances between ideal conductors of arbitrary shapes, orientations and sizes. The conductors can be embedded in a dielectric region composed of any number of constant-permittivity regions of any shape and size. The algorithm used in FastCap is an acceleration of the boundary-element technique for solving the integral equation associated with the multiple-conductor, multiple-dielectric capacitance extraction problem. The linear system resulting from the boundary-element discretization is solved using a generalized conjugate residual algorithm with a fast multipole algorithm to efficiently compute the iterates. --------------------- This version of fastcap has been cleaned up and enhanced by Stephen R. Whiteley of Whitleley Research Inc. ---------------------

Research, organize and share your family tree with GRAMPS (Genealogical Research and Analysis Management Programming System). Gramps gives you the ability to record the many details of an individual's life as well as the complex relationships between various people, places and events. All of your research is kept organized, searchable and as precise as you need it to be. The Gramps project strives to produce a genealogy program that is both intuitive for hobbyists and feature-complete for professional genealogists. It is a community project, created, developed and governed by genealogists. It is written in Python, using a GTK3 interface.

Open Babel is a project designed to pick up where Babel left off, as a cross-platform program and library designed to interconvert between many file formats used in molecular modeling and computational chemistry. Features currently include: * A huge variety of common chemical file formats * Recognition of file type based on filename extension * SMARTS matcher * Flexible atom typer * Gasteiger partial charge calculation * Hydrogen addition and deletion * Automatic feature perception (rings, hybridization, aromaticity) * Multiple conformer storage within molecules * Command line interface development class * Bitvector class * Open-source/Free Software under the GNU General Public License * Cross platform (Windows, Linux, Mac OS X, SGI, Solaris, Dreamcast...)

The h5py package provides both a high- and low-level interface to the HDF5 library from Python. The low-level interface is intended to be a complete wrapping of the HDF5 1.8 API, while the high-level component supports Python-style object-oriented access to HDF5 files, datasets and groups. The goal of this package is not to provide yet another scientific data model. It is an attempt to create as straightforward a binding as possible to the existing HDF5 API and abstractions, so that Python programs can easily deal with HDF5 files and exchange data with other HDF5-aware applications.

Firewalk is a network auditing tool that attempts to determine what transport protocols a given gateway will pass. Firewalk works by sending out TCP or UDP packets with a TTL one greater than the targeted gateway. If the gateway allows the traffic, it will forward the packets to the next hop where they will expire and elicit an ICMP_TIME_EXCEEDED message. If the gateway host does not allow the traffic, it will likely drop the packets on the floor and we will see no response.
