Free similiar software for linux

Scilab project is a is a numerical computation system similiar to Matlab or Simulink.

Scilab is an open source numerical computation platform developed by a consortium managed by INRIA (French National Institute for Research in Computer Science and Control) which, to date, gathers 23 industrial companies, research centers and engineer schools. It provides a powerful environment for the development of scientific applications and for engineering. Each month, nearly 20,000 remote downloads of
Scilab are registered from the Internet site of the Consortium, which takes Scilab one of the most valued pieces of open source scientific oftware.

Mandriva, whose membership to the Scilab Consortium is pending, and he Scilab Consortium agreed to integrate Scilab into the new Mandriva Linux 2007 distribution (Discovery, Powerpack and Powerpack+). The development teams of Scilab and Mandriva cooperated in the integration f the latest version of Scilab (v4.0, announced in February 2006 and since downloaded more than 150,000 times) into this new Mandriva release. It is planned to continue this arrangement for future versions of Mandriva Linux and of Scilab. In addition, Scilab will also be integrated into Corporate Desktop 4, the Mandriva Linux workstation for businesses.

About The Scilab Consortium

The Scilab software is, since May 2003, produced by a consortium, managed by INRIA, which, to date, has 23* industrial companies, research centers and engineering schools as members. The creation of the Scilab Consortium reflects a will to produce an open source numerical computation platform of high quality. Scilab is developed by a dedicated and permanent team hosted by INRIA. Moreover, its open source nature allows external contributions and thus a level of know-how in the field of scientific computation can be reached which a single company could otherwise claim only with difficulty. Nearly 20,000 remote downloads of the Scilab software are carried out each month from the official site of the Consortium to the benefit of European and foreign companies, universities and research centers. The
membership of the Scilab Consortium is in constant growth.

Pim Pam PONG is a PONG clone with a new look and in future versions, new interesting features.
Pim Pam PONG is a clone of the original PONG developed in the 70s. Pim Pam PONG has been developed using the SDL libraries: SDL, SDL_image, SDL_mixer, and SDL_ttf.
This permits the portability of the game to some systems and machines. It uses the NNG Engine (New Neopontec Gaming Engine) developed by Hector Blanco (me) that uses the mentioned SDL Libraries.
The game concept is the same as the original. You have the control of one bar that can move up or down in the screen, and the CPU controles the other bar.
A ball is launched in a random direction, and you must score in the other part of the screen. Is similiar to Tennis and Pim Pong.
Main features:
- 800x600 resolution at 32 bits.
- Low machine requirements.
- Easy and addictive playing experience.
- Cross-platform open source game: (binaries for Win32 & Linux, and sources for other systems).
- In future versions, more features will be added.

amarokNowPlaying is an amaroK script. It can generate two types of files: a text file (nowplaying.txt) with loads of information about the currently played track and the playlists settings and images with the album cover, artist and track name plus an image which you can use in your signature or similiar.

Please send me any comments, critique and/or suggestions.

gwanderer project is a GNOME puzzle game similiar to boulderdash.
It is a GNOME port of the old puzzle game wanderer (and later xwanderer).
Version restrictions:
- Its alpha release.
- Code is a mess but works.
- No hiscores, no config, no customization, still you can play.
- Not guaranteed to work with your system, patches are welcome.

MoxQuizz project is an IRC quiz/trivia script for eggdrop.
MoxQuizz is a multilingual IRC quiz/trivia script for eggdrops which acts as a game master.
A question is posted to the channel, and all chatter is searched for the answer. If something matches an answer or an optional regular expression, the user who said it receives a point. Highscores and an allstars table are managed.
Users can ask their own questions, too. A large set of German and English questions are provided, but you can easily run MoxQuizz with your own set.
There are numerous fun commands like !hug, !roll, and others.
Enhancements:
- moxtools: added code to enable users with flag Q to use a .!jump command similiar to the .jump for bot masters
- added three new question files with english questions (+788 questions)
- added option to prevent overruns (expert players entering a game at a late state and overrun the others to gain a high allstars score). When enabled, MoxQuizz does not accept new players as soon as one player reached a certain threshold in
- point (defaults to 15 points)
- added !antispam command to moxtools. Sends a antispam.txt file (if available and enabled) from the intl dir.
- public commands for quizmasters (flag P): !nuq, !uq, !listnuq for placing users in ignore for userquestsions (for 45 minutes)
- added .!identify to moxtools.tcl to manually force the script to identify to a nickserv (flag P)
- added another 185 german questions (thanks to "Said Nasser" and his users)
- MoxQuizz will purr if it gets patted (sometimes)
- dcc "!say !hug FOO" works again

buzztard project aims to provide a free replacement (or clone) of the currently windows only and closed source software Buzz. The buzz software is not really further developed, as the main developer has lost his source code.
We want to provide a music production environment, that is based on a very modular approach (following some of the ideas behind buzz), to allow many people to get involved. We hope that our software will have a better usabillity than buzz has although. We dont want to make this a 1:1 copy though.
The buzztard project itself has no direct link to buzz (apart from concepts). To allow migration for buzz users, we will provide song-file import and buzz-machine reuse.
The projects objective is a music application. If youve used programs like FastTracker or the original AMIGA SoundTracker, that will give you an idea. The buzztard editor uses a similiar concept, where a song consists of a sequence with tracks and in each track one uses patterns with events (musical notes and control changes). In contrast to the Tracker programs, tracks are not simply sample players. A song has a setup where one can arrange virtual audio plugins and link them together. Each of these machines can be controlled realtime or via patterns in the sequencer.
The buzztard editor will be just one possible application of the framework we will implement. Tools like a dj mixing application or a live session composer are other things that could be built using this framework.
The main goal is to get as far as buzz now is. Beyond that, we have thousands of ideas to make to improve the usability and production potential of such software. Buzztard should not be just a clone of buzz. It shall live beyond! Yay!
Enhancements:
- This version has lots of UI usability improvements, bug fixes, more instant apply settings and introduces some interactivity features (interaction controller and upnp playback controller).
- The gstreamer extension modules got two new interfaces for presets and help.
- A Fluidsynth generator plugin has been started.

KRDesktop is a GPL-ed KDE (QT3) front-end for QEMU. KQEmu project provides a GUI interface for running PC emulation (similiar in intent to Virtual PC/VMWare).
Written in Kommander, this also serves as a good example of RAD development under linux.
Main features:
- Creates script "Droplets" to automate later re-running with same settings.
- Supports all non "debug" features of QEmu.
Installation
Make sure you have QEmu and Kommander installed. Any version of QEmu should work, but KQEmu was only tested with the newest Alpha of Kommander (At this time Alpha 3).
Simply download and extract to a place of your choosing.
To run: kmdr-executor KQEmu-versionNumber.kmdr (ie: KQEmu-0.1.kmdr)

Kernux project is a fully kernel-mode http-daemon for Linux. Currently Kernux is in its developing stage. Similiar developments in the same area were khttpd by Arjan van de van and Tux web-server by Ingo Molnar.

Khttpd was included in the linux testing kernel 2.5 by Linus Torvalds. But it was actually not in kernel-mode of operation. Also it handled dynamic requests which is assumed to be insecure for the server OS by the Linux kernel developers.

Tux is another implementation of kernel mode http-daemon, being developed by RedHat. The developer is Ingo Molnar, the creator of O(n) scheduler, which control the procsses from Linux kernel version 7.2 onwards.

Kernux works as a kernel module, like a device driver. It uses low-level socket operations to handle the client requests. Kernux consist of a number of threads running parallely in the OS level (kernel_threads). An idle kernel-thread receive a connection from a wait queue, maintained at the Operating System level and serves it.

The pacularity is that, it uses no duplication of sockets what other servers do, but a single socket, whose access by multiple kernel-threads is maintained by a mutual exclusion system. Each thread, after analysing the request type, ie. whether it is static or dynamic, serves the client. The system is presently configured to handle only static requests. The dynamic requests are handled to a user-mode webserver of users choice, like Apache.
