Arianne is a multiplayer online games framework and engine to develop turn based and real time games.

It provides a simple way of creating games on a portable and robust server architecture. The server is coded in Java and uses Python for your game description, provides a MySQL backend and uses an UDP transport channel to communicate with dozens of players.

Our reference client engines are coded using Java and the C language in order to achieve maximum portability.

Arianne has been in development since 1999 and has evolved from a tiny application written in pseudo-C++ to a powerful, expandable but simple server framework, running on the Java platform, and a portable client framework, written in bare C to allow total portability of ariannes clients. Ariannes server is totally client agnostic.

Since the beginning, the key concept at the heart of Ariannes development has been KISS: Keep it simple, stupid!

Arianne games are playable. It now hosts several games:

* a multiplayer Gladiators fighting game
* a multiplayer Pacman game

All our efforts are supported by ariannes server: Marauroa.

Marauroa is completely written in Java using a multithreaded server architecture with a UDP oriented network protocol, a MySQL based persistence engine and a flexible game system. The game system is totally expandable and modifiable by game developers and is able to run Python scripts defining the games rules.

Marauroa is based on a design philosophy we called Action/Perception. Each turn a perception is send to the clients explaining what they currently perceive. Clients can ask the server to perform any action in their name using actions. Marauroa is totally game agnostic and makes very little assumptions about what are you trying to do, allowing a great freedom to create any game type.

Bugs are facts of life, they just happen.

On Arianne we care about code quality so code is fully tested using Test Units with JUnit and cppunit, so all modules are tested for most common cases, allowing a better quality software to be deployed.

The name originated from the Greek name Ariadne. (Latin; Arianna and from French; Arianne). Ariadne is a famous character in Greek mythology. She was the daughter of King Minos of Crete and she was in love with Theseus, the Athenian hero who killed the Minotaur ( a half human, half bull creature).

Theseus married her, however, then later left her alone on the island of Naxos. Ariadne later married Dionisos the God of Wine. The name Ariadne originates from the ancient Greek words ari which means intelligent and adnis which means pure (as in a virgin). Hence, the daughters of the Romans and Greeks where often called by this name.

DOFUS is a popular masive multiplayer RPG online game.

Story:

A long time ago....

.. a dragon named Bolgrot arrived in the eternal Province of Amakna. The young Rykke Errel was the only one to be courageous enough to face the terrible creature.
Instead of reducing him to dust as it could easily have done it, the dragon bowed down before the young knight and swore loyalty to him.

Months passed by...

Rykke met Helsephine, a young enchantress, and fell madly in love with her. When he introduced Helsephine to Bolgrot, Rykke would never have guessed what was about to happen.
The dragon, mad with rage, killed the sweet Helsephine and flew away, destroying everything on its way.
Rykke chased the dragon. When he found it, the old friends confronted each other in a titanic fight. Using his weapons and his magic, Rykke succeeded to bring Bolgrot down. But fatally injured, the young hero died short after.

Looking for an explanation...

... about the sudden violence of Bolgrot, the wise men of Amakna discovered within the entrails of the dragon six unusually colored eggs that were called DOFUS. Later on, it was discovered that when these eggs were reunited their power was absolute.

Absolute, but also unstable. The wise men decided to conceal those terrible relics from the rest of the world.

During the following centuries,

the secret of the existence of the DOFUS was so well kept that people eventually forgot all about them. But a cursed day among others, the guardians of the secret discovered that the DOFUS had disappeared. The news quickly spread, arousing terror and covetousness.

It didnt take long for adventurers to show up in Amakna, attracted by the prospect of glory or plunder. The destiny of Amakna was from then on uncertain and the appearance of numerous creatures as terrifying as theyre unknown added to the confusion.

online.php analyses /var/log/ppp-usage and displays connection statistics. It also prints some information about your current PPP connection.
Well, I was inspired by the script Onlinecalc by Michael Schlenstedt (Michael@adsl4linux.de). His script is heavily based upon "calc" by Ulrich Schmitz.
Since Onlinecalc did not fit my needs, I did a complete rewrite in php.
Main features:
- reads /var/log/ppp-usage and prints a table with a row for each month.
- also calculates the values of the current connection.
- completely written in PHP.
