Free galaxy theatres software for linux

Galaxy project is a stellar motion simulator which can show the development of a random field of stars into patterns such as clusters and spiral arms.

Galaxy is a free Linux computer program which simulates the motion of stars under the influence of gravity. Create a field of random stars to begin with, then watch the stars move as they are accelerated by their mutual gravitational attractions.

You can vary the number of stars, their initial velocities around a center, and the strength of the attractive force between them. Watch how the attractive forces accelerate individual stars and send them careening in new directions. Watch how large groups of stars develop into interesting patterns over time, such as clusters and spiral arms.

Galaxy is not for serious physics, but more a toy or educational aid for young students of science.

GalaXQL is an interactive SQL tutorial where the user can manipulate an OpenGL-rendered 3d galaxy using SQL.

WhereIsM13 is a free Java application designed to help us break out of our habitual way of perceiving the night sky as two dimensional.

It does this by displaying the common Messier objects in their three dimensional positions within or around the Milky Way.

Note: A more advanced version of this application is in the works. It will have:

- A more extensive object catalog
- The ability to zoom in and out of the galaxy view
- The ability to click objects plotted in the galaxy view to display their names and statics
- Printing
- Many other enhancements

Scum of the Universe is a space trading game that combines two genres: arcade and strategy. On one side, its a classic vertical-scrolling space shooter game. On the other side, it is an adventure and strategy. You should choose whether youll be an independent space trader, firearms smuggler, fierce freedom-fighter or something in between.

Following the main storyline, you go through the galaxy from one planet to another. Space travel requires fuel, so you need to keep earning money to buy it. You can also buy various upgrades for your spaceship and weapons that affect the arcade part of the game. The storyline itself is not linear. There are also some points where youll need to make decisions that will determine your destiny.

For thousands of years, people of planet Xen have colonized the planets in their galaxy. As time went by, many colonies grew unhappy about their status, as everything was controlled by Xen. Some of them organized military units and declared independence. You can see the status of each planet by "Rebel Sentiment" indicator. Planets with RS higher than 50% are ruled by the Rebel government, and Rebel laws apply.

Trading firearms is legal on planets ruled by Rebels, as they need as much firepower as they can get. On the other hand, Empire forbid all the trading with firearms and other ground weaponry as they wish to maintain their military advantage. One of the ways to make a lot of money is to buy cheap guns at Empire planets and sell them for a lot of money on Rebel planets where demand is extremely high. But be careful as youll need to fight Empire fleet once they find out youre a smuggler.

Beside the raging war between Xen Empire and the rebels there is increased activity of alien species, who destroy human ships. The stronger alien activity, the more waves of alien ships youll need to defeat in each planets outer orbit. Some of the aliens you destroy may drop artifacts (big blue ones) which you can sell at any space station for 20credits a piece.

Paradise 2000 represents my bend of the Paradise Netrek client. Paradise 2000 Netrek Client is not a fork, because that would imply parallel development, but no one else has done anything with the client since about five years ago.
Paradise 2000 is in fact one of the most, if not the most, actively developed Netrek clients available today. It is for Linux (and FreeBSD) only, and is not open source*. Dont let the Paradise name fool you, it works just fine on standard bronco servers. Nobody has even played a game of Paradise Netrek for years!
The biggest new feature of the client, not found in any other, is the sound system. While the old Paradise client, Ted Turner, COW, and COW ports (Netrek1999,2000) have a simple sound effect system, its crap. Especially the one used by COW. The Paradise/Ted Turner one is better, and is partially written by me, though you wouldnt know that*.
The Paradise 2000 sound system has psychoacoustic stereo effects that place sounds based on where they happen. If someone on the left blows up, you can tell they are on the left just from the sound. The newest version of Paradise-2000 has a sound system with speech output using IBMs ViaVoice TTS. If a teammate sends a carrying message, the client will actually say something like, "F one carrying five to org."
Main features:
- See weapons on galactic map
- Auto-rotate galaxy to put playing teams on left side
- Dashboard timer to show repair or refit time remaining
- See the army count for the planet your are orbiting
- Remap your keys via the help window. Just push the key you want over the name of the function you want to assign to it.
- Use the same key for both bombing armies and picking armies. The client can tell by context with one would make sense.
- You can set configuration options to different values for different server types.
- Double buffering support for graphics. When turned on, eliminates flicker. Very useful for LCD monitors.
- Extensive support for enhanced observer mode:
- See all players tractors and pressors while observing.
- You can lock onto a cloaked player and observe them.
- All your ship stats will reflect the player you are observing. Even torps out, kills, and army capacity.
- Your ship and player letter dont get drawn on top of the player you are observings ship and letter.
- Observers wont have stats shown in your player list, cluttering it up unnecessarily..
- Stereo sound effects!
- Highly configurable speech synthesis!
- Option to omit the team letter of ships on the galactic. Just show 0 instead of F0, since you can tell the team by the color of the letter.
- Game score on hockey servers calculated and put on the galactic for easy reference.
- Cool looking streaking background stars when transwarping on Bronco servers.
- Flags on the dashboard gauges indicating the fuel/shields/hull needed to refit or transwarp.
- Single key transwarp on Bronco servers. Push - to automatically lock onto your base and warp to it!
- 19FLAGS protocol enhancement. Reduces messed up flags from packetloss. Hockey players, this will eliminate stuck tractors and pressors.
- Works with WindowMaker. Window manager delete buttons work.
- Hockey bug fix, puck doesnt cloak at warp 15 or 31.
- Support for short packets 2. Reduces bandwidth and improves playability with packetloss.
- Supports SBHOURS feature, see how many base hours someone has.
- Shrink phasers, like BRMH.
- Support for wheel mice. The wheel will scroll the message windows, and can be bound to actions like other mouse buttons.
- Re-enter the game after dying by pushing the spacebar, instead of clicking on the right team window. Faster and prevents selecting the wrong team on accident in 4v4 hockey games.
- 32 position ship bitmaps. Your ship rotations will look smoother.
- Small red circle around ship shows det radius.
- Tic marks to show exact ship heading.
- Arrow on puck to indicate direction.
- ID of player you are tractoring displayed next to your ship.
- Configure what columns are in the player list, both the one-column and two-column list. You can also change the width of the each field, so show fewer digits for instance.
- UDP portswap option that lets the client work through NAT firewalls, like Linux IP_MASQ, without a special module.

SlackFire is an iptables script written especially for Slackware, my favourite Linux distribution in this corner of the Galaxy.
SlackFires main purpose is to protect a stand-alone machine or a small network with a stateful firewall that can be configured easily but in big detail.
Why another iptables script? There are a lot in the Internet, many of them with pretty nice GUI!
First of all, I didnt want to have a firewall that I only could manage and configure via GUI.
Next, I needed to work with a LAN with machines having routable IP addresses. Quite a few scripts available in the Net supported this feature.
Even lesser number of scripts supported configuration of fine-tuned rules. The majority of them just allowed all outgoing connections permitting replies to go back. I wanted to restrict outgoing traffic, too.
I also wanted that configuration can be performed without touching the main script and that this could be done by a person with very little knowledge about iptables.
Thus, I found it easier to write a script of my own than to tune a script written by somebody else.
Version restrictions:
- Currently, SF protects at most two network devices. All other network devices are not affected by the firewall in case packets are sent directly to the box running SF. Forwarded packets are dropped though. (The latter behaviour can be easily fixed.)
- I havent tried SF at machines that use DHCP. I expect that some tuning may be needed, especially in case the script is installed on a DHCP server.
- SF has only been tested on machines running Slackware >=9.0 with C locale. Certain things can break if messages produced by ifconfig and iptables use other languages than English. (This can be easily fixed if needed.)
- There is no support for NFS through a protected network interface yet. This will be fixed.
- Support of FreeS/WAN is not implemented.
There are undoubtedly more, partially because netfilter provides an incredibly rich range of possibilities. Actually, I havent seen an iptables script in the Internet with all the iptables possibilities implemented.
Enhancements:
- A minor change was made in bash syntax when proceeding configuration files.
- Temporary files are now created using mktemp.
