PDB2PQR is a Python software package that automates many of the common tasks of preparing structures for continuum electrostatics calculations, providing a platform-independent utility for converting protein files in PDB format to PQR format. These tasks include adding a limited number of missing heavy atoms to biomolecular structures, determining side-chain pKas, placing missing hydrogens, optimizing the protein for favorable hydrogen bonding, assigning charge and radius parameters from a variety of force fields.
phm Instant Messenger is a PHP class that can be used to manage users and friends that exchange messages. It can create and retrieve records in MySQL database tables that contain information of users, friends, and messages that they may exchange. Currently, the class implements several operations like authenticating users, changing user passwords, retrieving account password reminder questions and answers, creating user accounts, adding friends, searching for friends, retrieving user nick names, adding messages sent from one user to a friend, and retrieving messages received by a user.
blurt is Web publishing ("blogging") software. Unlike most blogging software, it does not provide you with a fancy back office, heavy duty database backends, and massive user management systems. Instead, you upload documents ("posts") in simple text format (.txt) to a directory on your Web server. blurt will figure out the rest.
Vibtoolbox is a set of command line tools for the analysis of vibration and acoustic test data. The interface design used for most of the tools in the package is the standard UNIX filter model. The tools take input on standard input and transform the input in some fashion, and then send the transformed input data to standard output. The tool set also defines ASCII and native binary database formats for the storage of vibration and acoustic laboratory and flight test data.
A-OK! The Wings of Mercury is a realistic simulation of the Mercury spacecraft. It features 3D graphics, fully functional control panels, networked simulations, and a complete manual. It uses the actual checklists used by the astronauts. Orbital and Sub-Orbital missions can be simulated. Orbital missions and a Mission Control Center simulator are available to registered users.
tsf is a command line utility for creating timestamped copies of files. When invoked on a file, a copy of that file is created with a name made of the file name plus a timestamp. When invoked again on the same timestamp mark, a copy with a timestamp plus a sub-index is created, and so on. tsf provides an easy and quick way for creating timestamped copies of files before modifying them.
