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...)

Machine Learning PY (mlpy) is a high-performance Python package for predictive modeling. It makes extensive use of numpy (http://scipy.org) to provide fast N-dimensional array manipulation and easy integration of C code. mlpy provides high level procedures that support, with few lines of code, the design of rich Data Analysis Protocols (DAPs) for preprocessing, clustering, predictive classification and feature selection. Methods are available for feature weighting and ranking, data resampling, error evaluation and experiment landscaping.The package includes tools to measure stability in sets of ranked feature lists.

Description: PAIDA is pure Python scientific analysis package and implements AIDA (Abstract Interfaces for Data Analysis). The main features are: - Pure Python! (so works on both Python and Jython) - Creating/Plotting the histogram, ntuple, profile and cloud - Fitting parameter optimization with constraints and its parabolic and asymmetric error evaluation - XML based storing

Ws2300 manipulates the LaCrosse WS-2300 weather station via its RS232 interface. It can read and write values, and can continuously log data from WS-2300 to a file or SQL database.

Crank is short for "CRyptANalysis toolKit", and its overall purpose is to provide a powerful and extensible environment for solving classical (pen-and-paper) ciphers, providing as much automation as possible. Classical ciphers include common schemes like monoalphabetic substitutions, where each letter of the alphabet is mapped to another (usually different) letter consistently through the text. The first version of Crank is restricting itself to these special ciphers. Other algorithms forever devoid of Crank's attentions include Enigma, RSA, DES, MurkelFish, or anything else invented after 1900. They're hard(er).

DenyHosts is a script intended to be run by *ix system administrators to help thwart ssh server attacks. If you've ever looked at your ssh log (/var/log/auth.log ) you may be alarmed to see how many hackers attempted to gain access to your server. Denyhosts helps you: - Parses /var/log/auth.log to find all login attempts - Can be run from the command line, cron or as a daemon (new in 0.9) - Records all failed login attempts for the user and offending host - For each host that exceeds a threshold count, records the evil host - Keeps track of each non-existent user (eg. sdada) when a login attempt failed. - Keeps track of each existing user (eg. root) when a login attempt failed. - Keeps track of each offending host (hosts can be purged ) - Keeps track of suspicious logins - Keeps track of the file offset, so that you can reparse the same file - When the log file is rotated, the script will detect it - Appends /etc/hosts.allow - Optionally sends an email of newly banned hosts and suspicious logins. - Resolves IP addresses to hostnames, if you want

This the stable version of Clam Antivirus. Clam Antivirus is command line virus scanner written entirely in C and its database is kept up to date. It also detects polymorphic viruses, scans compressed files and supported by AMaViS. Optionally you can use the clamav-milter interface to connect clamav with sendmail.

Doorman is a port knocking implementation which allows a server to run silently, invisibly, with all TCP ports closed except to those who know... the secret knock!

Bcrypt is a blowfish file encryption utility which aims for cross-platform portability. In addition to providing 448-bit encryption, bcrypt overwrites input files with random garbage before deletion in order to make low-level data recovery much more difficult.

BFBTester will perform checks of single and multiple argument command line overflows and environment variable overflows. BFBTester will also watch for tempfile creation activity to alert the user of any programs using unsafe tempfile names.
