Wapmess is a system that runs on any webserver (using PHP and MySQL) and enables the webserver-admin to set up a WAP-ICQ portal. This means that anyone with a mobile-phone (PDA or similar is also fine) that supports Wap 1.2 or higher can use the webserver to connect to an ICQ-account and send/receive messages via ICQ.

The goal with this project was to make it possible for almost any mobile-phone to use ICQ and be able to communicate with other users! One other goal with this project was to lower the GPRS-traffic in the phone and make the ICQ-ing cheaper. A third goal was to make this service as easy to log-in to as possible. Anyone tried to fill a log-in screen with a WAP-browser should know what I mean. With Wapmess all you have to do is to write your login-url ONCE and then bookmark it in your phone, to make it available fast.

The program supports protocol ICQ 8.0 (Tested with ICQ 2002, ICQ 2003, ICQ Lite etc.)

The Visualization ToolKit (VTK) is an open source, freely available software system for 3D computer graphics, image processing, and visualization used by thousands of researchers and developers around the world. Visualization Toolkit consists of a C++ class library, and several interpreted interface layers including Tcl/Tk, Java, and Python.
Professional support and products for VTK are provided by Kitware, Inc. VTK supports a wide variety of visualization algorithms including scalar, vector, tensor, texture, and volumetric methods; and advanced modeling techniques such as implicit modelling, polygon reduction, mesh smoothing, cutting, contouring, and Delaunay triangulation. In addition, dozens of imaging algorithms have been directly integrated to allow the user to mix 2D imaging / 3D graphics algorithms and data.
The design and implementation of the library has been strongly influenced by object-oriented principles. VTK has been installed and tested on nearly every Unix-based platform, PCs (Windows 98/ME/NT/2000/XP), and Mac OSX Jaguar or later.
Many resources exist to help you utilize the full potential of VTK in your application area. These resources include:

Scum of the Universe is a space trading game that combines two genres: arcade and strategy. On one side, its a classic vertical-scrolling space shooter game. On the other side, it is an adventure and strategy. You should choose whether youll be an independent space trader, firearms smuggler, fierce freedom-fighter or something in between.

Following the main storyline, you go through the galaxy from one planet to another. Space travel requires fuel, so you need to keep earning money to buy it. You can also buy various upgrades for your spaceship and weapons that affect the arcade part of the game. The storyline itself is not linear. There are also some points where youll need to make decisions that will determine your destiny.

For thousands of years, people of planet Xen have colonized the planets in their galaxy. As time went by, many colonies grew unhappy about their status, as everything was controlled by Xen. Some of them organized military units and declared independence. You can see the status of each planet by "Rebel Sentiment" indicator. Planets with RS higher than 50% are ruled by the Rebel government, and Rebel laws apply.

Trading firearms is legal on planets ruled by Rebels, as they need as much firepower as they can get. On the other hand, Empire forbid all the trading with firearms and other ground weaponry as they wish to maintain their military advantage. One of the ways to make a lot of money is to buy cheap guns at Empire planets and sell them for a lot of money on Rebel planets where demand is extremely high. But be careful as youll need to fight Empire fleet once they find out youre a smuggler.

Beside the raging war between Xen Empire and the rebels there is increased activity of alien species, who destroy human ships. The stronger alien activity, the more waves of alien ships youll need to defeat in each planets outer orbit. Some of the aliens you destroy may drop artifacts (big blue ones) which you can sell at any space station for 20credits a piece.

jukebox-control project is a complete automation for Sony A/V components featuring S-Link (CD, DVD, MD, etc).
jukebox-control includes a Linux driver module for an easy/dirty cheap to build DIY parallel to the Sony S-Link interface, plus Perl modules with both control-A1 (II) and control-S protocol implementations.
Its actually-incomplete development state makes it interesting for developers mostly.
Enhancements:
- Bidirectional Control-A1 protocol fully supported
- Unidirectional Control-S protocol implemented, not fully supported yet.
- New object model that ties A1 and S devices together under the same base class.
- CDDB support has been removed temporarily. I am rewriting most of the modules at this time.
- No real user interface. Hey! This is a interim release.

Hogwash is an inline packet scrubber that uses Snorts detection engine to drop malicious packets before they reach the target.

The original version of what is now hogwash was written in 1996 while I was at Idaho State University. I had a web server that when patched, broke the software it needed to run. The box was being taken over every other day so I wrote the very first version of hogwash to filter out the offending packets and name it Scrub.

A bunch of other admins were having the same problem so I distributed Scrub and patches started showing up in my mailbox. It became obvious that some sort of rules language was going to be needed. Over the weekend I wrote the original Cheap and Dirty detection engine.

The summer of 1999 I had an intership at the Idaho National Enviromental and Engineering Labs. They used Snort extensively. I liked the simple layout of Snort so I welded it into Scrub in place of the Cheap and Dirty engine and renamed the project to SnortScrub.

I left the INEEL to work for a startup in the dot-com era. The marketing department considered a commercial version of SnortScrub, but didnt like the name. SnortScrub got renamed to Hogwash as the stackless control channel and other goodies were added to it.

Around this time, Hogwash began to fragment as people needed custom functionality, there were a couple of dozen incompatible versions of Hogwash that were all being maintained seperately. Development of the public version ground to a halt.

As features were added, the Snort engine was showing its weaknesses for doing heavyweight packet scrubbing. The decision was made for resurrecting the old Cheap and Dirty engine and just put a snort compatibility layer on top of it.


That pretty much brings us up to date. The newly dubbed H2 engine will be in final release in the next couple of months.

Amanda is a client/server application for making remote backups. While originating from a UNIX environment, it also supports backups of windows machines (via the smbclient utility). Client software for other machines is planned. See the Amanda homepage for details.

Amanda CDRW-Taper program is a drop-in replacement for the taper component of the Amanda backup system. CDRW-Taper makes it possible to dump backups to CD-RW, DVD+RW or DVD-RW instead of tape. CDRW-Taper is licensed under the GNU general public license (version 2) (see COPYING for more information).

The original version of the CDRW-Taper simply copied the backed up data from Amandas holding disk to an intermediate directory. After the backup was finished, the CDRW-Taper program created an ISO-9660 image from the intermediate directory which was burnt on a CDRW.

After using this setup for about half a year it became clear, that CDRW media were simply too small for our purposes. While Amanda does support tape changers, the CDRW-Taper has no such equivalent.

One option was to move to a larger type of media, like DVD+R or "double density" CDRW, without changing the software. The other, at that time cheaper option was to change the software to emulate some kind of CDRW changer.

The idea is to have the taper copy the backed up data to several intermediate directories, each representing a single CDRW. After the backup is finished, these can be burnt to CDRW one by one. The changing of the media can be done manually.

The nice thing about this is that this way you can also back up to hard disk. Diskspace has become cheap, so you can have all of your backups available online, and still burn them all on removable media (to be stored in a safe place).

Meanwhile, DVD+RW have become sufficiently cheap to present an interesting alternative to the clumsy manual process involved with backups to multiple CDRW. Therefore, the current version has been extended to support backup to DVD+R/+RW and DVD-R/-RW media as well, using the dvd+rw-tools.
