BOXit is a small logic game for occasionally. Clear the playing field as far as possible, by dragging same-colored or equivalent tokens one over another, if they are in the same row or column on the playing field.

This is one of the games that are quick to learn but hard to handle. If you have fun in fast pace puzzling, BOXit is just right for you.

BOXit 2.0 is free software in the purposes of the Gnu GPL version 2 or newer.

JKhepera is a Java class library for Khepera mini robots. It includes a class which allows you to open connections from a host computer to the Khepera robot via a serial interface easily.
Communication between Khepera and a computer is also simple, using methods like "setSpeed" or "readProximitySensors".
In addition, there are GUI classes to display the whole communication for debugging purposes and to control the robot manually.
Main features:
- Open Source - JKhepera is published under the terms of GPL.
- Easy to handle communication between Khepera robots and a host computer via serial interface.
- The gui component KheperaPanel, to control Khepera manually
- The gui component KheperaMonitor, to display the complete communication between Khepera and a host computer for debugging purposes
- An Interface KheperaMotionalAlgorithm, that allows the implementation of individual control algorithms (additionally to the existing BraitenbergAlgorithm) to control Khepera automatically.
- The KheperaAgent, to control Khepera by an individual algorithm in an independent thread.

MySQL Activity Report is a valuable database tuning aid.

The MySQL Activity Report package is a tool to help MySQL database administrators to collect several database parameters and variables. These collected values can be used for server monitoring or performance tuning purposes.

The most important component of the MySQL Activity Report is mysqlard. This daemon collects the data from a MySQL server and stores these values in a Round Robin Database.

The mysqlard package also contains example graphing, cron and php scripts. The cron scripts can be used to keep archives of the generated graphics and the php script shows the generated graphics and tries to give some tuning tips.

The Pure Perl RayCaster is a small simple Ray casting application written completely in Perl without using any 3D API library or OpenGL. For the GUI, Pure Perl RayCaster uses wxPerl (WxWindows port to Perl).

Pure Perl RayCaster can load a 3D object from a file (in RAW format), display the object in wireframe perspective view, allow to orbit and zoom your camera and produce a user defined size ray casting image of the current view in a predefined color theme with or without smooth shading.

Pure Perl RayCaster is not a professional production tool for 3D image generation. It is well suited for educational purposes, in order to study, understand, tweak and try well known fundamental 3D Computer Graphics techniques.

mailman-pop3d provides a POP3 interface to GNU Mailman for the purposes of deleting spam which is stuck in the administrative requests queue.
If you manage a large Mailman mailing list, and are tired of using the web interface to discard spam, this script may be for you.
This software should be considered to be in beta stage; bugs are possibly present, and bug reports would be very much appreciated. At this point, I would also be very interested in hearing about success stories.
Enhancements:
- Improved logging messages.
- Development status changed from alpha to beta.

Digital Disco System is a client/server-based audio player for disco purposes as well as at-home usage. It has an console frontend (usable in shell scripts) and an X-fontend in the style of XMMS.

mod_cgi is an Apache module that turns a CGI program into a dynamically loaded library (.so) and runs it without forking. Gives the simplicity and portability of CGI without the overhead.

There is no documentation, beyond the source code comments. It will build cleanly with Apache 1.3b6+, and youll need some configuration: e.g.

AddHandler mod_ecgi .so

or

AddType x-embedded-cgi .so

As I said, see the source file.

Theres also a small harness for CGI programs, to get round the way many sloppy CGIs never return but call exit() instead. Its not absolutely necessary, but for most purposes youll want it.
