This is Seahaven Towers, a solitaire card game written for X11R4 and C++.

Installing

Type "./configure" (not necessary if you have gmake)

Type "make"

Test it by typing "./seahaven"

If everything looks good, become superuser and type "make install"

If you wish to edit the code, type "make depend"

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.

Ogrian Carpet project is a 3D fantasy action/strategy game.
Ogrian Carpet is an outdoor first person shooter game with real time strategy elements, inspired by the game Magic Carpet.
It uses Ogre3D as the renderer and allows you to fly around an island casting spells, summoning monsters, collecting mana, and building castles.
The object of the game is to build a castle, collect mana, and destroy your enemies. To build a castle, select a location, look at the ground, and cast the build spell. Note, you cannot build castles very close to water or other castles.
Your castle starts out small, with only one turret. As more mana is added to your castle, it will gain more turrets. Each turret adds another crane to your castles defense and another spell to your arsenal.
Basically, the game consists of fighting for control of mana. Whenever you encounter another wizard, shoot them with fireballs. If you hit them enough, they will "die" and be sent back to their castle. You are then free to claim all the mana in the area for yourself.
Once all the mana has been claimed, attack your enemys castle to get mana out of it so you can claim it for yourself. Once you enemys castle is out of mana, you can eliminate it by killing its heart. When all of your opponents have been banished, youve won.
Enhancements:
- AI bot player for skirmish
- things can now be loaded from an image, rather then randomly
- option for old randomized maps
- trees can now always bee seen
- made castle mana drops aggregate more
- loosened the restrictions on summoning
- made the config menu better
- added victory conditions to skirmish: kill all enemy towers/castles
- made ticks and gnomes stay in the formation you put them in
- made monsters and towers drop less then their cost when they have no wizard
- made mana float higher
- made towers cheaper (50)
- made sentinels drop much less (3)
- changed speed behavior on lava maps
- added victory music
- new music

Debian Live is a Debian SID Live CD.

The Debian Project is an association of individuals who have made common cause to create a free operating system. This operating system is called Debian GNU/Linux, or simply Debian for short. Debian systems currently use the Linux kernel. Linux is a completely free piece of software started by Linus Torvalds and supported by thousands of programmers worldwide.

Of course, the thing that people want is application software: programs to help them get what they want to do done, from editing documents to running a business to playing games to writing more software. Debian comes with over 8000 packages (precompiled software that is bundled up in a nice format for easy installation on your machine) - all of it free. Its a bit like a tower.

At the base is the kernel. On top of that are all the basic tools. Next is all the software that you run on the computer. At the top of the tower is Debian -- carefully organizing and fitting everything so it all works together.

Main features:
- Managing of preparations, yeasts and recipes
- Creating of a progress for every preparation
- Adding of evaluations
- Adding of labels
- Export as text file and as PDF document

PGID3 is an ID3v1 and v2 tag editor for manipulating the information on files such as MP3s. PGID3 Tag Editor project is written in PHP and uses PHP-GTK, so it can take advantage of the GTK+ Toolkit for rendering a GUI.

The program itself is broken into three parts, a PHP Function Library called Pid Three (Pid3), a PHP CLI interface (PCLID3), and the GTK+ GUI itself. All three parts come together ready to go, so do not go freaking about uber amounts of dependencies to fill. All together they create the PGID3 Tag Editor.

"But Bob," you might say, "PHP is for the web!" Sure it is, but you should then check out the link below for the PHP Command Line Interface. That document describes using PHP to develop shell and desktop applications. Why PHP? Because I like to abuse it, that is a little hobby of mine.

Simply, PGID3 is an ID3 tag editor for MP3 files. The ID3 tags are what tell your media player the information about the tune such as title, album, etc. You can get by with slack tags if you just use a player like XMMS or Winamp, but if you have a portable like an iPod or some kind of database for the files, then correct and neat tags are a must. PGID3 can handle both the v1 and v2 of ID3 tags.

As for the program itself, it is the combonation of three seperate pieces that together work to create a user friendly envrionment to manipulate your ID3 tags. The base of it all is the Pid Three Function library, which is a fully custom set of functions for the reading and writing of ID3 tags. Since these are seperate from the application itself, the actual dirty work of messing with the data can be easily updated as well as easily included into other projects.

The second part of PGID3 is the Command Line Interface that I have lovingly called PCLID3. Using this you can manipulate your tags from the command line without using any type of graphical front end. By not having this built into the GUI, the opportunity is left open to build alternate GUIs, or even just not use any at all.

The third and final piece is the PHP-GTK GUI. This is the actual PGID3 component, though all of the parts together form a complete package under the PGID3 name. I designed this GUI to be light, compact, and solve as many problems in one spot as possible. As a bonus feature, PGID3 has built in intergration with QueryXMMS which is a command line utility for Linux that can ask XMMS what is currently playing so PGID3 can open it. This speeds up editing of playlists considerably.

Enough acronymns, what about features? Well, it is an ID3 editor so the features I would expect to find in one is what it has. It has the ability to read, write, and strip ID3v1 and ID3v2 tags from files. You can open a file from anywhere in the filesystem with a dialog, or using the above mentioned QueryXMMS integration you can zap right to whatever XMMS is playing.

If you leave the comment field blank when you write a tag, it fills it in automaticly with "Tagged by PGID3" which might be an easily disabled in future releases - depends if I get any feedback on that. It also automaticly removes excess whitespace on the end of tags which if I recall correctly happens because Winamp pads with spaces instead of nuls. Anyway it cleans that for you. Stripping a tag automaticly unchecks the related checkbox for writing it back, and the boxes are dynamicly checked as you load a file depending if it already has a v1 or v2 tag.

There are also a few keyboard shortcuts. F1 toggles the Write ID3v1 checkbox, and F2 toggles the Write ID3v2 one. F9 opens the currently playing file in XMMS, and naturally Enter writes tags.

The Linux-Mobile-Guide is a guide for users of Linux and laptops, notebooks, PDAs and other mobile computers.
This guide was former known as Linux-Laptop-HOWTO but was now extended to cover Linux and mobile computer devices in general (laptops, PDAs, mobile cell phones, digital cameras, calculators, wearables, ...). These devices are different from desktop/tower computers.
They use certain hardware such as PCMCIA cards, infrared and BlueTooth ports, batteries, docking stations. Hardware parts cannot be changed as easily as in a desktops, e.g. the graphics card. Often their hardware is more limited (e.g. disk space, CPU speed).
Hardware support for Linux (and other operating systems) on mobile devices is sometimes more limited (e.g. graphics chips, internal modems). They often use specialized hardware, hence finding a driver can be more difficult. Many times they are used in changing environments, so there is a need for multiple configurations and additional security strategies.
The Linux-Mobile-Guide explains installation methods for laptops and PDAs and configurations for different (network) environments, security issues for portable computers and much more. TuxMobil is the origin of the Linux-Mobile-Guide and provides always the latest issue available for download.
