Free wing software for linux

wingS is a servlet development framework for Web applications. wingS project features Swing-like components and utilizes Swing models, Swing events, and a very similar API.
A special LayoutManager allows you to place components using designer provided HTML templates. The HTML code generation of the components themself supports PLAF (Pluggable Look and Feel), so it is possible to create a different output, like plain HTML, HTML+CSS, and WML.
Enhancements:
- [WGS-198] - Exception in SSLider
- [WGS-214] - Redirects and Error Page handling broken
- [WGS-189] - Fix cookie- less session management
- [WGS-196] - Documentation Update

The intel-wings project is a Linux driver for the Intel Wireless Series of input devices.
Somehow, Intel managed to avoid using the USB Human Interface Device standards with their wireless gamepads.
All other USB gamepads work out-of-the-box: plug it in, and the computer knows that it has an X axis, a Y axis, and six buttons. Not Intel. Thats where intel-wings comes in.
Wireless Series?
Yes, youve seen them. Everyone hated them. The keyboards were of poor manufacturing, the mice eat batteries like theres no tomorrow, and the whole system was ridiculously expensive. They were killed off by Intel several years ago -- after hitting the shelves and getting a lukewarm reaction, manufacturing was stopped, and support was terminated 18 months after release.
All of these complaints are valid. On the other hand, when used infrequently, the mice last a few months, and work great on a glass coffee table in my living room. (A newer wireless optical mouse wouldnt work.)
The gamepads are actually pretty fun, in my opinion: you can have a whole bunch of them attached to one base station, which is great for playing old console games with friends. You can get a complete set of devices for $10 on eBay, and with Linux-based PVRs becoming increasingly common, I find my devices to be a great addition to my living room.
Note that I wouldnt recommend the mice to anyone that uses their computer on a regular basis, but its easier for navigating menus than a remote control. In my opinion, the Intel Wireless Series devices on Linux PVRs are the way to go.
Enhancements:
- Preliminary keyboard support was added.
- The Intel wireless keyboards are at least partially functional.

No Gravity game is a futuristic and fantastic universe made of five intergalactic worlds. An arcade type game with great playability, where it is easy to plunge into space battles against spacefighters, space stations and more !

No Gravity is a space shooter in 3D a la Wing Commander. The player is controlling a space ship view from the first person. In each mission, the player need to accomplish some objectives, like shoot and destroys enemy ships or base, escorting some ships, clearing mine field, etc....

A brief description of the objectives is given at the beginning of a mission. In some situations, the player has some wingmen, and it can controls them by giving order like attack enemy, retreat, protect the base etc... A mission is composed of different sectors which has differents objectives.

When the objectives of the current sector is complete, the player needs to go the nearest NAV point, when he can wrap to the next sector. In the last sector, a warp gate is apparearing and the player need to go through it and complete the level. At the end of each episodes (one episode is 10 missions), there is a large base station to destroy.

When the player complete all the episodes (5 episodes), the game ends. The mission fails if : - The player got destroyed or - if an objective is not complete (like an important ship being destroyed by enemy).

Installation:

For Linux users, Download the No Gravity (Combo Bin+Data - Win32/Mac/Linux only)
for Linux i386 package and run the autopackage.

The FlightGear flight simulator project is an open-source, multi-platform, cooperative flight simulator development project. Source code for the entire project is available and licensed under the GNU General Public License.

The goal of the FlightGear project is to create a sophisticated flight simulator framework for use in research or academic environments, for the development and pursuit of other interesting flight simulation ideas, and as an end-user application. We are developing a sophisticated, open simulation framework that can be expanded and improved upon by anyone interested in contributing.

There are many exciting possibilities for an open, free flight sim. We hope that this project will be interesting and useful to many people in many areas.

FlightGear is a free flight simulator project. It is being developed through the gracious contributions of source code and spare time by many talented people from around the globe. Among the many goals of this project are the quest to minimize short cuts and "do things right", the quest to learn and advance knowledge, and the quest to have better toys to play with.

The idea for Flight Gear was born out of a dissatisfaction with current commercial PC flight simulators. A big problem with these simulators is their proprietariness and lack of extensibility. There are so many people across the world with great ideas for enhancing the currently available simulators who have the ability to write code, and who have a desire to learn and contribute. Many people involved in education and research could use a spiffy flight simulator frame work on which to build their own projects; however, commercial simulators do not lend themselves to modification and enhancement. The Flight Gear project is striving to fill these gaps.

There are a wide range of people interested and participating in this project. This is truly a global effort with contributors from just about every continent. Interests range from building a realistic home simulator out old airplane parts, to university research and instructional use, to simply having a viable alternative to commercial PC simulators.

Flight Dynamics Models

With FlightGear it is possible to choose between three primary Flight Dynamics Models. It is possible to add new dynamics models or even interface to external "proprietary" flight dynamics models:

1. JSBSim: JSBSim is a generic, 6DoF flight dynamics model for simulating the motion of flight vehicles. It is written in C++. JSBSim can be run in a standalone mode for batch runs, or it can be the driver for a larger simulation program that includes a visuals subsystem (such as FlightGear.) In both cases, aircraft are modeled in an XML configuration file, where the mass properties, aerodynamic and flight control properties are all defined.

2. YASim: This FDM is an integrated part of FlightGear and uses a different approach than JSBSim by simulating the effect of the airflow on the different parts of an aircraft. The advantage of this approach is that it is possible to perform the simulation based on geometry and mass information combined with more commonly available performance numbers for an aircraft. This allows for quickly constructing a plausibly behaving aircraft that matches published performance numbers without requiring all the traditional aerodynamic test data.

3. UIUC: This FDM is based on LaRCsim originally written by the NASA. UIUC extends the code by allowing aircraft configuration files instead and by adding code for simulation of aircraft under icing conditions.

UIUC (like JSBSim) uses lookup tables to retrieve the component aerodynamic force and moment coefficients for an aircraft... and then uses these coefficients to calculate the sum of the forces and moments acting on the aircraft.

Extensive and Accurate World Scenery Data Base

Over 20,000 real world airports included in the full scenery set.
Correct runway markings and placement, correct runway and approach lighting.
Taxiways available for many larger airports (even including the green center line lights when appropriate.)
Sloping runways (runways change elevation like they usually do in real life.)
Directional airport lighting that smoothly changes intensity as your relative view direction changes.
World scenery fits on 3 DVDs. (Im not sure thats a feature or a problem!) But it means we have pretty detailed coverage of the entire world.
Accurate terrain worldwide, based on the most recently released SRTM terrain data.) 3 arc second resolution (about 90m post spacing) for North and South America, Europe, Asia, Africa, and Australia.
Scenery includes all vmap0 lakes, rivers, roads, railroads, cities, towns, land cover, etc.
Nice scenery night lighting with ground lighting concentrated in urban areas (based on real maps) and headlights visible on major highways. This allows for realistic night VFR flying with the ability to spot towns and cities and follow roads.
Scenery tiles are paged (loaded/unloaded) in a separate thread to minimize the frame rate hit when you need to load new areas.

Accurate and Detailed Sky Model

FlightGear implements extremely accurate time of day modeling with correctly placed sun, moon, stars, and planets for the specified time and date. FlightGear can track the current computer clock time in order to correctly place the sun, moon, stars, etc. in their current and proper place relative to the earth. If its dawn in Sydney right now, its dawn in the sim right now when you locate yourself in virtual Sidney. The sun, moon, stars, and planets all follow their correct courses through the sky. This modeling also correctly takes into account seasonal effects so you have 24 hour days north of the arctic circle in the summer, etc. We also illuminate the correctly placed moon with the correctly placed sun to get the correct phase of the moon for the current time/date, just like in real life.

Flexible and Open Aircraft Modeling System

FlightGear has the ability to model a wide variety of aircraft. Currently you can fly the 1903 Wright Flyer, strange flapping wing "ornithopters", a 747 and A320, various military jets, and several light singles. FlightGear has the ability to model those aircraft and just about everything in between.

FlightGear has extremely smooth and fluid instrument animation that updates at the same rate as your out-the-window view updates (i.e. as fast as your computer can crank, and not artificially limited and chunky like in some sims.)

FlightGear has the infrastructure to allow aircraft designers to build fully animated, fully operational, fully interactive 3d cockpits (which even update and display correctly from external chase plane views.)

FlightGear realistically models real world instrument behavior. Instruments that lag in real life, lag correctly in FlightGear, gyro drift is modeled correctly, the magnetic compass is subject to aircraft body forces -- all those things that make real world flying a challenge.

FlightGear also accurately models many instrument and system failures. If the vacuum system fails, the HSI gyros spin down slowly with a corresponding degradation in response as well as a slowly increasing bias/error.

Moderate Hardware Requirements

The intention of FlightGear is to look nice, but not at the expense of other aspects of a realistic simulator. Our focus is not on competing in the "game" market and not on the ultra-flashy graphic tricks.

The result is a simulator with moderate hardware requirements to run at smooth frame rates. You can be reasonably happy on a $500-1000 (USD) machine (possibly even less if you are careful) and dont necessarily need $3000 (USD) worth of new hardware like you do with the many of the newest games.

That said, the more hardware you throw at FlightGear, the better it looks and runs, so dont feel like you have to chuck your expensive new hardware if you just purchased it. :-)

Internal Properties EXPOSED!

FlightGear allows users and aircraft designers access to a very large number of internal state variables via numerous internal and external access mechanisms. These state variables are organized into a convenient hierarchal "property" tree.

Using the properties tree it is possible to monitor just about any internal state variable in FlightGear. Its possible to remotely control FlightGear from an external script. You can create model animations, sound effects, instrument animations and network protocols for about any situation imaginable just by editing a small number of human readable configuration files. This is a powerful system that makes FlightGear immensely flexible, configurable, and adaptable.

Networking options

A number of networking options allow FlightGear to communicate with other instances of FlightGear, GPS receivers, external flight dynamics modules, external autopilot or control modules, as well as other software such as the Open Glass Cockpit project and the Atlas mapping utility.

A generic input/output option allows for a user defined output protocol to a file, serial port or network client.

A multi player protocol is available for using FlightGear on a local network in a multi aircraft environment, for example to practice formation flight or for tower simulation purposes.

The powerful network options make it possible to synchronize several instances of FlightGear allowing for a multi-display, or even a cave environment. If all instances are running at the same frame rate consistently, it is possible to get extremely good and tight synchronization between displays.

Flight Gear and its source code have intentionally been kept open, available, and free. In doing so, we are able to take advantage of the efforts of tremendously talented people from around the world. Contrast this with the traditional approach of commercial software vendors, who are limited by the collective ability of the people they can hire and pay. Our approach brings its own unique challenges and difficulties, but we are confident (and other similarly structured projects have demonstrated) that in the long run we can outclass the commercial "competition."

Contributing to Flight Gear can be educational and a lot of fun. A long time developer, Curtis Olson, had this to say about working on Flight Gear:

Personally, Flight Gear has been a great learning experience for me. I have been exposed to many new ideas and have learned a tremendous amount of "good stuff" in the process of discussing and implementing various Flight Gear subsystems. If for no other reason, this alone makes it all worth while.

GNU Go is a free program that plays the game of Go. GNU Go has played thousands of games on the NNGS Go server.

GNU Go is now also playing regularly on the Legend Go Server in Taiwan, on the WING server in Japan, and many volunteers run GNU Go clients on KGS. GNU Go has established itself as the leading non-commercial go program in the recent tournaments that it has taken part in.

Sudognu is a command line sudoku solver and creator. Sudognu can display the logical steps it uses to find the solution. It can print four sudokus to a pdf page and it comes with example cgi scripts for integration into www sites (see sudognu @ work below).
This project is written in C and tested on Linux. In order to compile and install sudognu you need Haru Free PDF library.
Enhancements:
- This release applies the forcing chain after X-wing, swordfish, and jellyfish, improves the documentation, adds a -P option for reordering solution techniques, facilitates browsing of sudoku solutions, and adds minor bugfixes.

RSS Editor is a Firefox extension that acts as a desktop RSS editor for casual editing of RSS 2.0 files.

Sudoku Savant is a simple GUI-driven application to solve and generate Sudoku puzzles through logical means.

Sudoku Savant generates and solves standard Sudoku puzzles with anything from 3x3 to 5x6 or 6x5 grids, using the following strategies:

- Singletons
- Locked candidates
- Number subsets
- X-Wings, Swordfish and Jellyfish
- Both Simple and Multi-Colouring.

These strategies should be enough to provide a step by step solution for any Sudoku puzzle that you are likely to find in a newspaper or magazine, although Savant can also resort to "trial and error" if presented with something really pathologically nasty. (This will at least confirm that the puzzles solution is unique.)

You may also parameterise or turn off the more advanced strategies, to see whether they were really needed.

Finally, Sudoku Savant lets you solve the puzzle by hand, providing hints, cell colouring, up to 4 pencil marks per cell, and the ability to high-light any incorrect moves. A partially completed puzzle can be saved in a simple text format so that you can continue solving it later.
