Free sodium explosion software for linux

This program places the required number of sodium ions around a system of electric charges, e.g., the atoms of a biological macromolecule (protein, DNA, protein/DNA complex).

The ions are placed in the nodes of a cubic grid, in which the electrostatic energy achieves the smallest values. The energy is re-computed after placement of each ion. A simple Coulombic formula is used for the energy:

Energy(R) = Sum(i_atoms,ions) Q_i / |R-R_i|

All the constants are dropped out from this formula, resulting in some weird energy units; that doesnt matter for the purpose of energy comparison. To speed the program up, the atoms of the macromolecule are re-located to the grid nodes, closest to their original locations.

The resulting error is believed to be minor, compared to that resulting from the one-by-one ions placement, or from using the simplified energy function. The coordinates of the placed ions are printed out in the PDB format for further usage.

It is recommended that the placed ions are equilibrated in a separate Monte Carlo or Molecular Dynamics simulation. Trivial modifications to the program should allow the placement of any combination of multivalent ions of different charges.

XPilot project is a multi-player 2D client/server space game.
XPilot is a multi-player 2D space game. Some features are borrowed from classics like the Atari coin-ups Asteroids and Gravitar, and the home-computer games Thrust (Commodore 64) and Gravity Force (Commodore Amiga), but XPilot has many new aspects too.
Main features:
- True client/server based game; optimal speed for every player.
- Meta server with up to date information about servers hosting games around the world.
- A web of world-wide rating servers; compare your skills with pilots from all around the world, and climb the ladder of the world-wide rating list.
- Real physics; particles of explosions and sparks from your engines all affect you if youre hit by them. This makes it possible to kill someone by blowing them into a wall with engine thrust or shock waves from explosions.
- Specialized editors for editing ship-shapes and maps.
- Game objective and gameplay adjustable through a number of options, specified on the commandline, in special option files, or in the map files. Examples of modes of the game:
- classical dogfight; equipped with only your gun, you have to rely on your maneuvering and tactical skills
- team; fight together, steal other teamss treasures (involves flying around with a ball in a string, much like in Thrust) and blow up their targets (which are, no doubt, heavily guarded)
- all out nuclear war; chose carefully between more than twenty weapon and defense systems to stay alive and annihilate your enemies
- race; make it through the deadly course before your opponents
- Adjustable gravity; adjustable by putting special attractors or deflectors in the world, or by adjusting the global gravity in various ways.
- Cannons and personalized and vengeful robot fighters give you a hard time.
- Watch your energy, and remember to dock with a fuel station to refuel before its too late.
- Defend your home base, or terrorize and steal someone elses.
- Equip your ship with the 15+ defense and weapon systems: afterburners, cloaking devices, sensors, transporters, extra cannons, mines and bombs, rockets (smarts, torpedos and nuclear), ECM, laser, extra tanks, autopilot etc.
To start playing, you need to connect to a server by using a client program called xpilot. There are always servers running if you check with the meta server, but if you for some reason do not want to join them, youll have to start a server of your own (see man-page xpilots(6)).
Enhancements:
- Team cannons could kill teammates with laser pulses. Fixed.
- On the map Death Star one can destroy a large number of targets with one FNC. This results in packet buffer overflows and slow updates. To overcome this a smarter map update algorithm is implemented in the server and also map updates are now limited to max 2 KB per network packet.
- The default score font was reduced from 15 to 13.
- When the server sends map updates to the client these are now always acknowledged immediately by the client. This should help prevent stalls or lock-ups on maps where are a large number of targets or cannons can be destroyed. It should also reduce the number of very big server frame update packets.
- Robots no longer try to go after players who arent in playing mode.

Really Rather Good Battles In Space is a real time strategy game with fleets of spaceships.

Crogai consists of a mixture of crowd simulation, AI, and genetic algorithms.

It is possible to set up simulations and test different AI in a full 3D environment with a small physics engine, terrain, collision handling, etc. Crogai is inspired by the OpenSteer projet and uses steering behaviors as building blocks for the AI.

The agents can graze, hunt each other, and emit spores for reproduction. A genetic algorithm allows the agents to evolve, and let them decide whether to do so or not. In addition, the examples provided by the project make nice screensavers.

In addition, agents can emit spores in the environment, and those are in turn used in a genetic algorithm to evolve the agents. Many interesting behaviors are observed, population explosions and extinctions are common. A framework is also available to use machine learning algorithms instead of the currently explicit AI, like neural networks, but not only.

Crogai is working in both graphics and batch mode thanks to a simulator-base architecture, allowing a real time / simulation time ratio of any arbitrary value, depending on the machine capacities.

xscorch project is a a game about annihilating enemy tanks using overpowered guns.
Xscorch is a clone of the classic DOS game "Scorched Earth".
The basic goal is to annihilate enemy tanks using overpowered guns.
Players can purchase weapons and accessories to defend their tank, and they can attack enemy tanks by adjusting the angle of the tanks turret and the firing power.
Xscorch supports gameplay with humans and computer AIs, and network gameplay is in development.
Enhancements:
KNOWN BUGS:
- Some moves/items are interpreted locally instead of sent through the network server like they should be. It contributes to desync.
- Graphics/Computers are fast - hangs and crashes have been reported.
- The wedge code sometimes draws straight ends instead of rounded ones.
- Leap Frogs fail to leap in Interleaved Mode, because the land is not cleared by one explosion before the next missile is animated...
- The man page is out of date enough to notice.
BUG FIXES:
- Removed excessive assertion in seconomy-gtk.c (thanks Gunnar).
- Fix snet header file inclusion.
- Only sa_handler OR sa_sigaction in handler (cross compatibility).
- Repaired two bugs in sgame/soptions.c (fixes solaris compiles).
MISCELLANEOUS:
- License restricted to version 2 of the GPL.
- Easter Egg wars :)
- Fixed #warnings or changed them to /* TEMP */ for 0.2.0 release.

Apache Portals is a collaborative software development project dedicated to providing robust, full-featured, commercial-quality, and freely available Portal related software on a wide variety of platforms and programming languages.

This project is managed in cooperation with various individuals worldwide (both independent and company-affiliated experts), who use the Internet to communicate, plan, and develop Portal software and related documentation.

Modern software is complex and expensive, which has motivated many companies to invest in enterprise portals as a mechanism by which they can manage information in a cohesive and structured fashion.

Portals offer many advantages over other software applications. First, they provide a single point of entry for employees, partners, and customers. Second, portals can access Web services transparently from any device in virtually any location. Third, portals are highly flexible; they can exist in the form of B2E intra-nets, B2B extra-nets, or B2C inter-nets. Fourth, portals can be combined to form a portal network that can span a companys entire enterprise system, allowing for access both inside and outside the firewall.

Portals have many advantages, which is why they have become the de facto standard for Web application delivery. In fact, analysts have predicted that portals will become the next generation for the desktop environment.

Portals distinguish themselves from other software systems because they provide the ability to integrate disparate systems and leverage the functionality provided by those systems. As such, they are not mutually exclusive, and do not force you into an either-or decision vis-a-vis existing software systems. This point is of paramount importance, particularly when you consider the fact that Web services are destined to fuel the explosion of Web applications. Since portals can access any Web services, the conclusion is inescapable: portals provide a unique opportunity to leverage the functionality of nascent technologies as well as mature, well-established software systems.
