Free kingdoms of classification software for linux

Pattern Classification Program is an open-source machine learning program for supervised and unsupervised classification of patterns (vectors of measurements). Pattern Classification Program implements the following algorithms and methods:
- k-means clustering
- Fishers linear discriminant
- dimension reduction using Singular Value Decomposition
- Principal Component Analysis
- feature subset selection
- Bayes error estimation
- parametric classifiers (linear and quadratic)
- least-squares (pseudo-inverse) linear discriminant
- k-Nearest Neighbor
- neural networks (Multi-Layer Perceptron)
- Support Vector Machine algorithm
- cross-validation
- bagging (committee) classification
The program supports interactive and batch processing. Commands are issued through a keyboard-driven menu system in the interactive mode, or in a batch file in the batch mode. It is a binary executable and does not need any special run-time environment. PCP uses tab-delimited text files for input data. The results are displayed on the screen and saved in text files.
PCP runs under Linux and Windows operating systems (under Cygwin environment), on i386 architecture CPUs such as Intel Pentium or AMD Athlon. PCP has been developed and tested on RedHat Linux 9.0 distribution. It has also been tested on SUSE Linux 9.1 and Fedora Core 2 and verified to run on Knoppix 3.7 and Windows XP.
Enhancements:
- This release supports model selection for the linear SVM kernel and an option to build SVD transforms using training and test datasets (as opposed to just training data).
- P-errors are now reported in SVM model selection.
- The build process was simplified.

3D Spatialization of Sound is a Linux/X11 port of the 3D spatializer library from the CRC.

This program creates "directional" stereo sound from mono source. CRC folks told me I shouldnt have raised the sampling frequency without adjusting other stuff.

Oh well. This was a proof-of-concept type project anyway. I think to get correct 3D effect, you need to drop sampling rate back to 11025.

To Build the X11 implementation:

1. make
2. cp audio-filter /usr/local/bin
3. mpg123 -m -s some_music.mp3 | audio-filter | aplay -S -s 44100 -f s16l -

audio-filter is implemented as a filter, it reads signed 16 bit mono input at 44100 khz from stdin, and outputs signed 16 bit stereo, 44100 khz output to stdout. You can replace mpg123 with any sound source generating signed 16 bit 44100 khz mono signal. "aplay" is a sound player utility which comes with ALSA linux sound driver. You can use "play" from the sox package, or "ampctl", or any other sound player that would read 44100 khz, signed 16 bit stereo raw data from stdin. For "sox" play script, you would replace "aplay" command line with "play -c 2 -f s -r 44100 -s w -t raw -"

If everything is good, a 640x480 window will come up, with some cryptic writing on the top, a filled circle with an arrow pointing right, and a empty circle slightly to the right of the circle with arrow.

NOTE, that just like in the original Windows implementation, the axiss are reversed. The arrow on the "head" is pointing "forward". So, in the default startup configuration, the sound is located in front of the listener. Moving the sound source "up" moves it to the left of the listener, and "down", to the right. You can visualize this well if you turn your monitor 90 degrees counter
clock wise.

The filled circle with an arrow is your "head"
The empty circle is the "sound source"

You can move the "sound source" around by clicking the mouse at any position in the window, or by clicking on the "sound source" circle, and dragging it to the desired position. Soundfield will be dynamically updated as you do this.

You can move the "head" by moving the mouse to desired position, and right-clicking. The "head" icon will move to the new position and soundfield will be updated.

World of Padman is a multiplayer Fun Action Shooter at Q3 Engine base.

World of Padman was a popular total conversation mod for the quake 3 engine.

Since the release of the gpled sourcecode, their team-members are worked hard to brush up the maps, models and the whole bunch of other things that belongs to a superior mod. They Invented new weapons, gaming goals on so on.

Today it is the day to proudly anounce the availibility of WoP for Linux, MacOsX and Windows, also.

The standalone game is an funshooter at its best! Come and try it for free, you have nothing to invest but your download time.

The game comes absolutly free as in beer. For details for the copyrighted graphics read at the project site http://worldofpadman.com.

Art of Illusion is a free, open source 3D graphics studio.

Art of Illusion combines modelling, animation, texturing and rendering in one application, with advanced features which compare favorably to those found in many commercial programs.

Art of Illusion is written entirely in Java. It should (in theory) work under any Java Virtual Machine (JVM) which is compatible with Suns Java Development Kit (JDK) 1.4 or later.

Defend the Kingdom project is a real-time strategy based game.

Defend The Kingdom, or Defender for short, is a real time strategy game dedicated to the fantastic world of LARP.

Its goals include the ability to build and control a complete fantasy world (with towns, poeple, etc.), control armies of knights and creatures to fight against your strongest enemies, gain power and resources by trading with your friends, and many more.

System Configuration Collector in short SCC, collects configuration data of systems in snapshots. The structure of the snapshot allows SCC to compare a snapshot with the previous one and detect changes in the configuration.
Upon detecting changes, scc adds the differences to a logbook. The snapshot and the logbook are converted to HTML for local inspection. Optionally, the SCC-files can be send to a system running the SCC server software. On the server, summaries of the SCC-data are generated and search/compare operations on the snapshots and logbooks are available via a web-interface.
The logbook is a starting point in case a system "suddenly" does not work correctly and the administrator is wondering what he/she has changed in the last weeks or months. As most of us know by experience, configuration changes can have accidental side-effects on (other) systems.
By examining the entries in the logbooks and considering the consequences, the cause of an actual problem might be found more easily than by just trying to remember the changes that were performed.
The snapshots can be used to compare the configuration of two systems. Imagine systems, that are supposed to be identical, but behave differently. Comparing parts of the snapshots of the two systems can indicate the cause of the difference in behavior.
Enhancements:
- The DIV tags in the HTML was corrected.
- Directory data/transfer was created to avoid errors in scc-pull. cpu-speed for SunOS was added.
- The machinfo variable is now initialized.
- The determination of local filesystems on Linux was corrected.
- Squid classification was corrected.

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
