Free runs on software for linux

xrockman is a retro arcade/puzzle game based on Rockman for the VIC20 by M & S Srebalius and published by Mastertronic in the 1980s.

xrockman is written for Xlib so requires little in the way of dependencies and runs on slow computers.

The project is licensed under the terms of the GPL.

To build, ensure that libx11-dev is installed and then say "make".

The "Virtual Universe" is a 3D cyberspace which offers more possibilities than just chat: it is a combination of the Web, chat, and instant messaging within a realistic, three-dimensional cyberspace.
The "Virtual Universe" is a virtual reality environment which runs on top of the Internet.
Main features:
- chat with each other
- see the chat-partner as a virtual, three-dimensional person
- interact and communicate
- be creative in many ways
- create own worlds for any desired subject
Enhancements:
- A lighting bug in .COB/.SCN loader has been fixed.

RSS2Cisco is a script that runs on server and converts RSS feeds in Ciscos IP phone XML format for use as a service. This script will take RSS feeds and convert them to be displayed on Ciscos IP based phones such as the 7920, 7940 and 7960.

ploticus is a free, GPL, non-interactive software package for producing plots, charts, and graphics from data. ploticus was developed in a Unix/C environment and runs on various Unix, Linux, and win32 systems.

ploticus is good for automated or just-in-time graph generation, handles date and time data nicely, and has basic statistical capabilities. It allows significant user control over colors, styles, options and details.

From the command line you can run ploticus using the pl command. The pl command can also be invoked via CGI. C developers can use libploticus. Other interfaces exist for packages such as Python.

HampusDB is a small, flexible and efficient hierarchical database. It comes with a wide support of command line utilities for manipulating and extracting data.

Its designed for both embedded and bigger systems. HampusDB currently runs on Linux and has interfaces to C, C++, Java and Perl.

HDB aims to fill the gap when storing data in a relational database is too rigid and storing data in textfiles is too cumbersome.

A typical example would be when you have heirarchical data such as XML or configuration data that you want to store and retrieve in a flexible manner.

SDL_sound is a library that handles the decoding of several popular sound file formats, such as .WAV and .MP3. It is meant to make the programmers sound playback tasks simpler. The programmer gives SDL_sound a filename, or feeds it data directly from one of many sources, and then reads the decoded waveform data back at her leisure.
If resource constraints are a concern, SDL_sound can process sound data in programmer-specified blocks. Alternately, SDL_sound can decode a whole sound file and hand back a single pointer to the whole waveform. SDL_sound can also handle sample rate, audio format, and channel conversion on-the-fly and behind-the-scenes, if the programmer desires.
As the name implies, SDL_sound is an add-on to Simple Directmedia Layer, and as such, youll need it to build and use SDL_sound. SDL gives us lots of convenience for porting and implementing some elements of the library, not to mention that it is a powerful, cross platform answer to DirectX. You should definitely look into it, whether you use SDL_sound or not.
Places SDL_sound is known to be used:
- The Ambient Music System uses SDL_sound in its player module.
- The popular game glTron uses SDL_sound for sound playback.
- Dominik Haumann wrote in to mention C++ wrappers for SDL_sound, which can be found here.
- MusicBox, a GNUstep music manager, uses SDL_sound to decode various audio formats.
- The SuSE Linux distribution has been know to package SDL_sound (at least version 0.1.5 has been spotted in the wild).
- Gentoo Linux distributes SDL_sound via their "portage" system. Just "emerge sdl-sound".
- FreeBSD has SDL_sound in their Ports tree: herere the details.
- NetBSD Appears to have packaged SDL_sound, too: details.
- Debian has packaged SDL_sound, too: details.
- ROCK Linux has an SDL_sound package: details.
- Probably other places. Email me if you want to be listed here.
