Free gear 2 software for linux

Gear project draws a gear in an open office drawing.

You can then load the open office drawing and a nice looking gear is shown.

You can adapt the nr of tooth from the commandline, the shape of the tooth can be changed from the source.

How does it work?

I unzipped an open office drawing and looked how the lines in a file were made, then i automatically generated the lines into the content.xml file and zip the stuff again to make a valid document.

Isnt it great to have open formats (that are also well readable...)!!!

What is essential...

Well, in the archive that you got this program in, there is a odg directory this contains all the files that make up a valid OpenOffice drawing. The program should be run in a place where this odg directory is found...

example you unzipped this archive in a temp directory and now your file tree looks
like this : temp/gear/odg
then you should run the gear program from the temp/gear directory. .

well, it isnt that hard, you will figure it out...

Boomer project is a general purpose modeling and simulation program.

It provides the estimation of parameter values by non-linear weighted least squares regression or the simulation of complex systems of differential equations.

Parameter estimation can be by normal or Bayesian methods. A comprehensive list of weighting schemes is included. The model to be analyzed can be entered as a system of integrated equations or as a system of differential equations.

Differential equations are solved by a classical fourth order Runge-Kutta method, a fourth order Runge-Kutta-Gill method, a four/five Runge-Kutta-Fehlberg method, an Adams predictor-corrector method, or Gears method for stiff equations.

Simulation with random error in parameters or data are also possible. A batch run can be repeated many times to assist in Monte Carlo type studies.

Installation:

Untar the downloaded file with

tar -xvzf fboomer312a.tar.gz

As an administrator user you can move boomer to your PATH and thereby invoke the program globally. The command:

sudo cp boomer /usr/bin/boomer

Enter password

from your download folder (where the new version of boomer resides) will put boomer in a directory usually included in your PATH variable. This can be checked with the command:

echo $PATH

I havent checked this with Linux/Fedora yet but something similar should work. I only get limited time on my younger sons game machine.

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.

Search-Engine-Optimized project is a free online resource for anyone who wants to step up their search engine optimization strategies to the next gear.
The web is a constantly changing place, expecially search engines, but there are numerous search engine optimization strategies that are consistant across all the major search engines, and are probably going to be very useful for a long time to come.
Read on to learn what they are and how to employ them in the development of your web site.
Main features:
SEO Rank Checker is a nice little script for checking your keyword status for a few select keywords without going through the trouble of checking the search engine result pages yourself.
- Automated fetching of the top 100 results for MSN, Yahoo and Google to check for your site.
- Easy to read, compare and print output
- Installation is super easy, just upload to your server and youre done!
- Super small script, just a few KBs of space!

SpamFirewall is a mail server filter script that automatically blocks mail servers that send too much spam.
This first version of the software is alittle hard coded. I want to make it more
modular with a client/server setup, plugins for different firewall systems, and
plugins for spam matching. At present however its geared toward postfix, iptables
and spamassassin.
To run te firewall make these steps:
Run spamfirewall.sql against your mysql server. Or the update sql patches.
Modify spamfirewall and spamfirewallmaintenance to match your mysql users prefs, spam thresholds, and expire times.
Add spamfirewall to your MTAs filter script. An example filter.sh is included.
Add spamfirewallmaintenance to cron. For example the following /etc/crontab line to run once an hour:
09 */1 * * * root /usr/local/bin/spamfirewallmaintenance >/dev/null
Main features:
- - Automatically queues the IP addresses of mail servers and spammers from messages
- that match the spam rules.
- Automatically firewall those mailservers and spammers if they send enough spam to meet your desired threshold.
- Automatically removes IP addresses from the queue and from the blocked list after a specified expiration period.
- Each repeat offense from a spammer will increase the amount of time they are blocked. With good behavior the amount of time will decrease.

Jaffer project is a Java implementation of Appletalk File Protocol v3.1 using TCP Transport. Performance on a Gigabit network exceeds both Samba and Netatalk. No, Really. Disable debugging.
Quick start:
This program will act like a native Appletalk file server. You must run it as root to use Appletalks normal port 548. But its just as happy running on any unpriviledged port. To access shadow passwords, the server must be run as root.
Your client must be a Mac OS X 10.2 or newer system.
Download a recent build and source code.
Or browse the source in svn.
Run the server:
java -jar jaffer.jar -config [config-file]
or, alternatively, for quick testing:
java -jar jaffer.jar -server [port] [volume-name] [path-to-export]
From the OS X Client, mount the new volume:
mount_afp afp://[user]:[pass]@[host]:[port]/[volume-name] [mount-point]
The [user]:[pass]@ part of the url is optional. If omitted, the mount will be attempted as a Guest user.
Developers:
Most of your work will most likely be done in the AFP_Session class implementing additional AFP calls. When you do this, please be mindful of comments in the code. They are sparse, but very important. When you add call implementations, please make sure they are represented in the AFP_Constants file and annotated with the page number in the AFP3.1 reference PDF.
Most of the implementation is geared towards AFP3.1 which means that some of the helper and common methods are not usable for AFP2.3 or earlier protocols.
Enhancements:
- added zipfs, refactoring for jdk1.5

blueMarine project is about an open source workflow for digital photography.

What does it mean?

Start thinking of an opensource application like Aperture or Lightroom that enables you to organize, develop, print and publish your photos. Pretty standard stuff nowadays. Opensource, at first sight, means that the application is free. Now think of an application written with the Java™ language: the application runs everywhere, Mac OS X, Linux, Windows. Now think of a community of people that adds code, plugins, crazy ideas, integrating some of the latest, cool technologies around, such as GPS positioning or geo-mapping.

Well, this is just the core concept of the blueMarine project.

Lets go on and lets think of the workflow. For the existing commercial applications the workflow starts just after shooting the photo and ends with a print on paper, the photo archived and maybe a web gallery published.

Just for a starter, we could do these things in innovative ways. For instance, trip reports could take advantage of GPS positioning data and Google Maps. Galleries could be presented in form of a virtual 3d gallery with walls and pictures hang on them.

Thinking of it twice, there are holes in workflows supported by current commercial applications. For instance, if you want to filter your images with a sophisticated noise reduction algorithm or if you want to create a bigger composite photo out of several shots, you likely have to use an external application. Some communities, such as amateur astrophotographers, need some very special processing that is usually performed by means of specific software. Wouldnt be better to have all of these facilities integrated in a single front end?

Now, lets broaden our workflow horizon. It can extend well beyond the print or the archival. For instance, an ornithologist usually manages field notes about the bird observed and photographed: directly binding them to photos and maybe GPS positioning data is much better than keeping a separate Excel sheet. It can also start much before shooting the photo. Think of trip planning: maybe you travel to nice places and spot interesting subjects, but not all the conditions are favorable: the weather, the light, the sun position, or the season (snow, blossomed flowers, foliage colors). Maybe you take some photos but at home you decide: hey, Im going to return there next Fall when the trees are reddish. Wouldnt be cool if a software application could allow you to easily manage all of these wanna-shoot-again photos, maybe providing assistance to guess which will be the sun position in a certain day and hour and integrating weather forecasts? And synthetising a trip program that can be uploaded on your palm gear?

Theres a further point with opensource photo workflow. Its related to the world of camera raw formats, that is the way professional DSLR cameras work. They provide you with the raw bits from the sensor that need to be extensively cooked, or developed, for getting a good image. This approach gives a tremendous amount of control to the photographers - too bad that most formats are proprietary and not documented. blueMarine supports the OpenRAW initiative and provide an opensource implementation of developing tools for camera raw formats from an ever increasing number of vendors.

Well, all of this and more is the aim of the blueMarine project.
