Otter is a layer of usability enhancements to the OTRS ticketing system. It includes enhanced reporting, enhanced event management via the GUI, and out of the box configurations for various use cases. Currently Help Desk and Membership systems are supported as out of the box use cases.
dynalogin is a distributed two-factor authentication suite that combines a secure UNIX server and API with an Android soft token. Open standards (HOTP, TOTP, and soon OCRA) are used for one-time passwords. A C library is provided for inclusion in existing software and Web sites. OpenID (using SimpleID) is supported for Web applications and single sign on. PAM is supported for easy UNIX and LDAP integration (SASL, RADIUS, and JAAS in development). It works with Google Authenticator or the dynalogin Android application.
Me and My Shadow is a puzzle/platform game in which you try to reach the exit by solving puzzles. Spikes, moving blocks, fragile blocks, and much more stand between you and the exit. Record your moves and let your shadow mimic them to reach blocks you couldn't reach alone. Play through over 40 levels and use the built-in level editor to make your own.
crackxls2003 breaks the encryption on Microsoft Excel and Word 97/2000/XP/2002/2003 files which have been encrypted using the RC4 method. These files are encrypted using a 40-bit-long key. It will not work on files encrypted using versions later than 2007 or versions 95 or earlier, or if a non-default encryption method was used.
PyDate is a very simple Python/Tk based tool to adjust the system date and time conveniently from an easy to use graphical interface. It is primarily intended to be used with minimal desktop environments like IceWm that don't provide such tools themselves. KDE or Gnome libraries are not required.
EZDM (ezdungeonmaster) is a simple set of tools for dungeon managers, targeting AD&D 2nd edition rules. It's not an RPG game, but some helper tools for people DM-ing real games, and is designed not to get in the way of roleplay and storytelling, but simply help do the math during encounters and leveling. Dice rolling can be done by the computer, or the tools can be set for manual dice, in which case you simply enter the results of the roll. All game data, charts, and character sheets are stored in JSON format. The EZDM kit defaults to using a simple dialog-based GUI which requires easygui, but a console interface is also available.
The underling library provides simple, scalable means to manipulate MPI-parallel, three dimensional pencil decompositions using FFTW. Pencil decompositions are a natural way to distribute O(n^3) data across O(n^2) processors and are well-suited for memory-intensive, structured spectral turbulence simulations and postprocessing codes. It may be useful in other domains as well. The library is written in C99 and may be used by C89 or C++ applications.
Storing binary (boolean) matrices where each element is a byte (or worse, a 32 or 64 bit integer) is incredibly inefficient and wasteful, both in time and space. For example, a 10k square matrix requires 400Mb of RAM if stored as 32 bit int values. Binmat is a library that bit-packs these matrices so that this 10k square matrix requires just 12.5Mb (the minimum space possible). More than that, binmat takes advantage of extremely fast bit-operations when multiplying matrices. The usual series of multiplications and additions required to compute each element are replaced by bitwise AND and OR operations. Furthermore, on 64-bit hardware each bitwise operation can replace up to 64 multiplications or additions, reducing operations that can take hundreds of clock cycles down to just a single cycle. This gives rise to some very considerable performance increases, especially when taking the power of a matrix. Binary exponentiation is implemented to further improve the performance of higher matrix powers.
