Free no charges software for linux

n-genes is a powerful Genetic Algorithms and Programming toolkit written for Java 5.
Using advanced object oriented techniques, like generics and introspection, it is one the simplest system to learn and use. N-geness design allows fast coding and a total flexibility.
n-genes is an open-source project released under GPL. It is free of charges.
Main features:
Stack-based Genetic Programming
The Genetic Programming implemented in n-genes relies on a linear postfix programs, close to Forth or Postscript programming languages. They allow the following advantages:
- High-level and turing-complete language (through flow-control instructions);
- Extendable and customisable instruction set;
- Possibility of using faster and simpler GA operators;
- Efficient bloat removing/controlling algorithms.
Modularity and Dynamic Config Files
All parts of evolutionary computing have been made components, through " Design Patterns" methodology. The benefits are:
- Separation of the behaviour from the representation, i.e. we can use the same operators for a GA doubles individual or for a GP problem;
- Short and readable code, since each object represents only a single operation and therfore has few and shorts methods.
- The possibility to change the components or their behaviour during evolution, for example changing dynamically the size of a population or using self-adaptating mutation operators.
The n-genes platform is coupled with a dynamic config file system. This system is able to instanciate whatever class, passing arbitrary parameters of whaterver types, whithout needing to extend the parser. Object introspection is used at initialisation.
Performances Optimisations
n-genes was written with high performance computing in mind. Here are the optimisations you get for free, using our platform:
- Object-recycling memory management, eliminating the time spent on objects allocation and garbage-collections;
- Efficient individual-level fitness cache, the fitness is lazy-computed and cached until the individual is mutated;
- Population-level individual cache, saving computation time when the population diversity dimish.

After decades of war one company, who had gained powerful supplying both sides with weaponary, steps forwards and crushes both warring factions in one swift movement.
Using far superior weaponary and AI craft, the company was completely unstoppable and now no one can stand in their way.
Thousands began to perish under the iron fist of the company. The people cried out for a saviour, for someone to light this dark hour... and someone did.
Main features:
- 26 missions over 4 star systems
- Primary and Secondary Weapons (including a laser cannon and a charge weapon)
- A weapon powerup system
- Wingmates
- Missions with Primary and Secondary Objectives
- A Variety of Missions (Protect, Destroy, etc)
- 13 different music tracks
- Boss battles

Bandwidth Check is a small utility that helps an administrator measure the available bandwidth. In order to make use of this utility, you will need to turn on the chargen service, which is provided in many inetd implementations.

In order to make use of this utility, you will need to turn on chargen protocol.

To enable chargen on Linux:

create the following file /etc/xinetd.d/charge
service chargen
{
type = INTERNAL
id = chargen-stream
socket_type = stream
protocol = tcp
user = root
wait = no
disable = no
}
service xinetd restart

To Compile bwcheck

gcc -o bwcheck bwcheck.c

To execute

./bwcheck

./bwcheck 172.16.11.2

No Friction is a roll-a-ball-and-collect-the-dots puzzle game.

In this simple puzzle game, you control a rolling ball that has to collect the green dots and make it to the end of each level.

The ball can only be sent rolling if its sitting still, and it only stops when it hits a wall; it cant change direction once its moving.

It sounds simple, but there are 20 progressively harder levels - only a master can beat them all, and piece together the code that reveals the solution to Level X.
There is also a secret level, and the entrance is hidden underneath a breakable block somewhere in the game.

Keys:

Enter: Restart current level
F: Toggle fullscreen mode
F2: Return to the selection screen
F3: Save what level youre currently on
F4: Load a level youve previously saved

Vocabulary Trainer project is a flashcard vocabulary training system.
You can use language modules to change the language of its interface and can choose one of three learning modes (Random, Often-unknown words, and Seldom-asked words).
Main features:
- Inquiry after foreign word or meaning
- Optional Attention of upper- and lowercase
- Limitation of time to simulate tests (optional)
- Saving of right, wrong and prompted vocabularies
- Inquiry after: Random order, as given, often unknown vocabularies, seldom asked vocabularies
- Multilingual Interface, changeable with languagefiles
- This program is Open Source, the Delphi-sourcecode kann be downloaded under "Downloads"
- Free of charge
- No further restrictions

No-Referrer is a Firefox extension that adds an entry to the context menu that lets you open a link in a new tab, without sending the referrer information.

No Tab Close Button is an extension which removes the close buttons on the tabs.

Removes the close buttons on the tabs (Firefox 2)
Removes the button on the right (Firefox 1.x).

For people that like to close their tabs with a middle click.
