Secret of Eternia 0.3
Secret of Eternia project is a 2D RPG using ClanLib. more>>
Secret of Eternia project is a 2D RPG using ClanLib.
The eaisest way to get started is to use an example map from the game itself. Open up (File-Open) the first map in the maps/ folder (maps/1.fmp). You will notice that the map looks exactly like the first screen of the game demo!
You will notice the screen is divided into 2 main sections. The larger section is the preview of the map you are working on. The left side menu is a listing of all avaliable blocks that you currently have in the map. You can click on a block to set it as your current brush. This is similar to choosing a paint color in a paint program. Once you select a block, you can then edit the map by clicking in the map area. This is the generic way to edit the map.
Play around with this map to create some different landscapes and such using many blocks. You can even save the map and start up SoE to see your changes! (Make sure you have a backup of the original map, or you will have to download the game again).
Enhancements:
- Bug fixes! See the forum for detailed information.
- Lua support is added in. (see docs/ for how to use this)
- Lighting effects are here!
- Fully Working Windows Support

MINIX 3.1.3a
MINIX 3 is a new open-source operating system designed to be highly reliable and secure. more>>
MINIX 3 is a new open-source operating system designed to be highly reliable and secure. This project is based somewhat on previous versions of MINIX, but is fundamentally different in many key ways.
MINIX 1 and 2 were intended as teaching tools; MINIX 3 adds the new goal of being usable as a serious system on resource-limited and embedded computers and for applications requiring high reliability.
This new OS is extremely small, with the part that runs in kernel mode under 4000 lines of executable code. The parts that run in user mode are divided into small modules, well insulated from one another.
For example, each device driver runs as a separate user-mode process so a bug in a driver (by far the biggest source of bugs in any operating system), cannot bring down the entire OS.
In fact, most of the time when a driver crashes it is automatically replaced without requiring any user intervention, without requiring rebooting, and without affecting running programs. These features, the tiny amount of kernel code, and other aspects greatly enhance system reliability.
MINIX 3 is initially targeted at the following areas:
- Applications where very high reliability is required
- Single-chip, small-RAM, low-power, $100 laptop for Third-World children
- Embedded systems (e.g., cameras, DVD recorders, cell phones)
- Applications where the GPL is too restrictive (MINIX 3 uses a BSD-type license)
- Education (e.g., operating systems courses at universities)
Main features:
- POSIX compliant
- Networking with TCP/IP
- Two ANSI C compilers (ACK and gcc)
- Over 300 UNIX programs
- Many improvements since V2
- Full multiuser and multiprogramming
- Support for memory up to 4 GB
- Device drivers run as user processes
- Full C source code supplied
- Runs on 386, 486, Pentium, etc.
To run MINIX 3, you need a PC driven by a 386, 486, or Pentium CPU or compatible. The standard configuration requires 16 MB of RAM. An 8-MB version is also available, but it is slower due to a smaller buffer cache. Since the distribution comes on a live CD, you can test it without allocating any hard disk space, but for a hard disk installation, 200 MB is needed as a minimum, 400 MB minimum if you want all the sources.

Mobile Device Information 1.2.2
The Mobile Device Information project is a Java Swing application that provides desktop interface access to the WURFL. more>>
Mobile Device Information project is a Java Swing application that provides desktop interface access to the WURFL (Wireless Universal Resource FiLe).
The WURFL contains information about the capabilities of a huge number of wireless devices.
The project has been created by me (Jim McLachlan), a software consultant specialising in Java projects for mobile devices (primarily J2METM clients with J2EETM back-ends).
Part of my consultancy work has been the "education" of clients to the limitations of the cross-platform nature of Java on mobile devices. I have regularly had to field questions like "Is the < mobile device > MIDP-1.0 or MIDP-2.0 compliant?" and "How many different MIDP-2.0 devices are there?".
As part of my recent web site development, where I intend to sell my J2ME applications, I found myself in need of some "rich content" that would be useful to consumers and not just developers. Hopefully, this tool will be useful to people wanting to know more about their devices.
Enhancements:
- This release finally resolves problems with the id pseudo-capability.
- Version 1.2 caused make/model data to be hidden; 1.2.1 fixed this, but added a bug which used the fallback instead of the current "id".

CTF Beta2
CTF project is a multi-agent capture-the-flag framework for education. more>>
CTF project is a multi-agent capture-the-flag framework for education.
This project was started by Jason Rohrer during the fall of 2000 and was initially used to teach CS 472, Introduction to AI, at Cornell University.
A homework assignment was given that asked students to design a CTF agent for the framework.
Students in the class responded to the assignment with great enthusiasm, and many of their final agents far exceeded our expectations (one student group went so far as to design a genetic algorithm to evolve a team of agents).
CTF forces students to explore the issues surrounding agents that operate in a limited information environments.
The framework is flexible enough to allow almost any possible implementation of agent control, from the simplest reactive agents, to agents that query powerful knowledge bases, to neural network agents that are trained by back propagation or reinforcement methods.
When using this framework at Cornell, we left the assignment open-ended. However, you can use this framework in your own class to teach a specific agent control concept (by forcing every student to implement a reinforcement learning system, for example).
Main features:
- Runtime loading of agent classes-- plugging new agents into the framework is incredibly easy
- Runtime loading of obstacle maps
- Automatic round-robin tournament system
- Automatic grading-- an email-ready message is generated for each student team at the end of the tournament (a script for sending out the email messages is included); the point system can be completely configured
- Assignment handout-- click here to see an example of the instructions we handed out to students for CS 472 at Cornell
- Licensed under GPL-- if the framework doesnt work for you as is, you can improve it yourself

The MW software consists of:
- a set of model builders, simulators and their associated scripting environments.
- a word processor for creating hypertext.
- an authoring system for constructing your own graphical user interfaces for your own simulations.
- an embedded-assessment system that allows you to design your own questions and collects student data.
- a special browser for you to deliver and for the users to access stuff created using the above sub-systems.
- Web services for collaboration among authors, students and teachers.
All these sub-systems are seamlessly integrated behind an easy-to-use graphical user interface. The customizability of models through the authoring system allows you to design user interfaces appropriate to your audience, without having to get them involved in the complexity of the modeling engines.

Realms of Rivalry
Realms of Rivalry is an online tactical rpg. more>>
Realms of Rivalry is an online tactical rpg. Play short skirmishes in random-generated game worlds.
The game can be summarized as an online graphical turn-based strategy/rpg game where you can play short tactical skirmishes with 2-4 players in small random-generated game worlds. The game is free and can be played either as an applet or downloadable client.
The time-limited turns (30-90 secs) give the game a semi-realtime feel, and the game has sometimes been characterized as "chess on steroids".
Main features:
- Community friendly game lobby where you can chat with others and join realms.
- Up to 4 players simultaneously battling on the same realm.
- Players control teams of 3 characters: Warrior, Archer and Mage.
- Time-limited turn-based gameplay.
- Random-generated game worlds (realms).
- CPU controlled monsters.
- Several weapons, armor, traps and other items.
- Occlusion calculation used in combat situations.
- Interrupts.
- Different types of terrain.
- Buy & sell items at vendors.
- Monster respawning.
- Ingame chat.
- Detailed end-of-game summary panel.
Explore the map and kill creatures to obtain weapons, potions, runes, traps and more to aid you in your quest for domination!
The game development has been very "test-driven" in the sense that the game quickly was made playable and that features and changes were added and removed continuously during development. This hopefully improves gameplay, but of course at the expense of dramatically increased development time.
Realms of rivalry was never intended to "soothe the masses", but were made entirely to match the game that we ourselves would like to play - something we have done for many, many hours :-) But of course, some of you might enjoy this game aswell, and that is why we decided to share it with you!.

Slast 1.4.2 Beta 1
Slast project (formerly Slasterisk) is a live cd project combining Slax and Asterisk 1.4. more>>
With the ease of modifying Slax to create a custom cd, you can have a live cd with your Asterisk install on it, doing whatever you need a pbx to do. Slast is great for demonstrating/testing Asterisk, learning Asterisk, and with the loading into ram, you can have a very powerful backup if your Asterisk box were to go down.
Slax is modular, so we hope to have a repository of user submitted modules here for you to add to your personal Slast cd.
If you want to help with anything from website design to creating modules and writing documentation, please contact droops (at) gmail to volunteer.
Why Another Distro?
This is a good question. We think that this has a place for 2 reasons, education of Asterisk and custom Asterisk live-cds. The config files have been moved and only the necessary ones remain. They have been rewritten to make getting Asterisk working, for the newcomer, the top priority.

active acoustic vibration control 0.0.1
active acoustic vibration control is a set of basic tools for monitoring and modulating audio noise. more>>
active acoustic vibration control tool is a set of basic tools for monitoring and modulating audio noise.
The tools aim toward a set of codes and algorithms for monitoring noise signal and modulation and reducing them using active noise control priciples.
Active noise control and soundproofing is a relativly recent development (first researched around 30 years ago), and has been in constant development for many and varied situations and applications.
The basic concept of active noise control is the aplication of equal and opposite force to cancel out vibration.
The project attempts to provide a starting point and library for experimentation into various methods of digital signal processing for active noise reduction and soundproofing.
Noise cancellation has been used in many environments currently active control is best used in constant vibrations with lower frequencys.
The principle is of controlling the noise level by adding an equal and opposite sound to the noise in the environment. The basic principle may be simple but the actual effectivness depends on many environmental factors.
Generally simplistic out of phase sound wave is used which works to some extent and requires little processing (a simple XOR with -1) this will tend to leave a large number of artifacts as the amplitude of higher frequency components (above i->o delay time) rises.
i->o processing delay
e transducer efficiency
p sound propagation characteristics
r reflections
The project aims to provide a framework for many dsp architectures, dac/adc chips, transducers and monitors.
Create tools for acoustic calibration and data logging hardware
To simplify implementation of active noise and vibration control systems.
To provide an open source standard for use within the industry and education.
To encourage hardware producers to distribute standard interface descriptions for their hardware
Enable low cost development of systems using COTS consumer hardware for noise and vibration control.

Once started, GCompris presents a graphical view that includes from top to bottom:
1. Boards icon list Each icon represent a board. When you move the mouse over them, they are highlighted and the name and description of the board is displayed in the board description area.
2. Boards description area Display a small description of what the highlited board icon is about. Note that the descriptions are internationalized which means translated in a target language (See section Internationalization Issues for more information on Internationalization).
3. Control bar: The control bar is always present in GCompris. This icons are contextual which means that when an icon is not meaningfull in a specific context, it is simply not displayed. The control bar contains the icons from left to right:
1. Help: In some case, a board can be too complex to be described in the Board description area. In this case this will provide access to the additionnal instructions.
2. Level: Some boards provide different level. The number of levels is board dependant.
3. OK: Some boards do not automatically detect that the child has finish the given task. Clicking here is similar to entering RET on the keyboard and thus the RET key is a shortcut.
4. End: End the current board if any, otherwise Exit GCompris. When entered at the board menu level, it will create a dialog window to confirm the Exit of GCompris.
5. About: Display the about box for gcompris with the version number, the author, the licence and links to online resources.
