Free hobbyist software for linux

RobotFlow is a mobile robotics tookit based on the FlowDesigner project. FlowDesigner is a data-flow oriented architecture, similar to Simulink (Matlab) or Labview that is free (LGPL) and versatile.
The visual programming interface provided in the FlowDesigner project will help people to better visualize & understand what is really happening in the robots control loops, sensors, actuators, by using graphical probes and debugging in real-time.
The work on RobotFlow has begun in september 2001 as an University of Sherbrooke project in the Mobile Robotics and Intelligent Systems Laboratory (LABORIUS). The work on the project still continues and will become available to everybody through SourceForge as a LGPL project.
We hope with this toolkit to create a standard & open platform that all people from hobbyists to researchers could use and improve over time. It primarily supports Linux/Unix using the GNOME GUI.
The FlowDesigner & the Robotflow toolkit are written in C++ and provide fully customizable control and processing blocks :
- Drivers & interfaces for Pioneer2 Robots
- Vision processing algorithms (color training & tracking, etc.)
- Player / Stage simulator drivers for FlowDesigner/RobotFlow
- Signal processing algorithms (audio + video)
- Basic Behaviors
- Fuzzy Logic control
- Artificial Neural Networks
- Embedded super blocks (subnets, iterators)
- Basic networking (TCP/IP, broadcast)
- Device control (Sony EVI-D30, SICK lasers, etc.)
- Finite State Machine (beta)
Networks created with the visual interface called "flowdesigner" can also be run as scripts (with no graphical interface), enabling robots with lower resources to fully take advantage of FlowDesigner / RobotFlow. FlowDesigner provides an easy way to create your own data types/structures and blocks as toolkits.
Enhancements:
- This release was updated to work with FlowDesigner 0.9 and MARIE 0.4.
- A RobotFlow namespace was created.
- OpenCV 0.9.6 library support with image tracking (text, color, features) and face tracking algorithms was added.
- New behaviors are included.
- Configure scripts were updated.
- The SNCRZ30 RS-232 driver was fixed.

Fight Win Prevail (or FWP for short) is a hobbyist multiplayer first person shooter. Fight Win Prevail is set in an imaginary universe where fearless pilots fight to the death with their futuristic vehicles.
Gameplay lies somewhere between the Mechwarrior-series and Quake 3. It is faster and more action-orientated than in Mechwarrior, but tries to avoid the jump-around-like-crazy-and-fire-at-everything-that-moves-gameplay known from Quake 3.
Fight Win Prevail is a pure multiplayer game and does not have a real singleplayer mode. Our primary target are LANs, but the game is playable over the internet, too.
Main features:
- Good graphics, physics, sound, and gameplay (for a hobbyist game)
- Multiplayer over TCP/IP
- 3 types of vehicles with individual characteristics (mechs, hovercrafts, and helicopter-like aircrafts)
- Distinct weapon types (classical projectile weapons, beam weapons, ballistic weapons, etc.)
- Distinct map types (from close combat indoor maps to large landscapes)
- An extendable set of vehicles, weapons, and maps
- 4 game modes (deathmatch, team deathmatch, sole survivor, team survivor)

Whats New in 4.2 Alpha 1 Development Release:
- ClarkConnect Community 4.2 Alpha 1 is available. Though it has only been four months since the last release, version 4.2 brings quite a few new features. This alpha build is intended for developers, integrators and curious users. Typical uses for this alpha build: final integration testing for third party developers; testing new hardware and drivers with the Linux 2.6.18 kernel; getting a sneak preview of the upcoming 4.2 release. This is alpha software, so quite a few software modules are still incomplete or not well tested. The most important known issues are: Webconfig template graphics and icons are incomplete; graphical console tool does not display on the screen properly....

2-Disk X window embedded Linux is a very efficient Linux/xwindows distribution, implementing a net centric operating environment and user friendly GUI
The distribution is intended to be a demonstration of Mungkie assiciates embedded appliance development environment, showing the sort of environment that can be created for small appliance GUI systems using less than 4Mb flash and 4Mb RAM.

JD4X project is a basic GUI Windowing Environment developed to support the Java Programming Language based on top of the X Window system. It was developed with the intention of providing a Java environment that allows Java programmers to build and extend a windowing system purely in Java. However, the project itself is not pure Java and uses a mixture of Java and C.

JD4X is targeted at the hobbyist programmers who desire to put their skills to the test by customizing a desktop of their own. To do this, the JD4X project sets out to provide a native structural foundation that gives them a greater degree of control over their desktop, JVMs and Java classes that runs on the Linux X Window system, thereby giving the Java programmer full control of their desktop environment.

The project also targets Java users who may desire a Java enabled and component based desktop without excluding other native applications already found on their Linux distribution. It does this by also providing a default windowing desktop to cater to the end users who can select a mixture of native and Java applications that they like on their desktop without having to differentiate between them and the way they are executed.

In general, JD4X aims to isolate the underlying platform system to the background and provide a fully Java GUI front end. JD4X is not about a Java only desktop. It is about empowering the Java user and programmer such that the Java desktop will meet their particular needs.
