Free stock market simulation software for linux

Mars Simulation Project is a free software Java project to create a simulation of future human settlement of Mars.
The simulation is a multi-agent artificial society set in a detailed virtual world.
XML configuration files allow the user to modify the simulation properties.
The Mars Simulation Projects main window contains the following components:
- Menu Bar
- Search Tool
- Time Tool
- Mars Navigator
- Monitor Tool
- Rover Info Window
- Settlement Info Window
- Person Info Window
- Unit Bar
The Mars Simulation Project can be configured with a number of XML configuration files located in the "conf/" directory. It is recommended that you save a backup copy of a configuration file before modifying it in case there is an error and the simulation cannot read the modified configuration file.
Here are the configuration files you can modify for the simulation. You will need to start a new simulation for any changes to be loaded in.
- buildings.xml
- crops.xml
- landmarks.xml
- malfunctions.xml
- medical.xml
- people.xml
- settlements.xml
- simulation.xml
- vehicles.xml
Enhancements:
- This release includes the new mission tool for viewing, creating, and editing missions as well as plenty of bugfixes.

Multi-Simulator Interface, in shrot MSI, is a simulation interconnection engine. In other words it is a program that connects simulations together by synchronizing their clocks and data. Multi-Simulation Interface serves the same purpose as HLA and supports most of HLAs functionality (and more).
The MSI is an HLA alternative. The major motivating factors in the design of the MSI are speed, interoperability, and ease of use.
The MSI was written as a cutting edge distributed simulation component to connect multiple instances of ATLs premiere simulation software, CSIM, and it can be used to interface any compatible simulations.
How does the MSI compare to HLA?
The MSI was originally created to be just a light weight HLA RTI. However, as it was written, limitations in HLA were discovered. The MSI is an improvement on both the design and implementation of HLA. Some highlights include:
A 1,536 to 1 reduction in size over the publicly available (until late 2002) HLA RTI.
At least one order of magnitude of bandwidth consumption less than the publicly available (until late 2002) HLA RTI.
The ability to subscribe to an object name in addition to a type.
Time synchronization that allows for proper causality when used with discrete event simulators.
Support for systems-of-systems (SoS) and hierarchically organized simulations.
Availability for many platforms.
MSI Concept - A Synchronized Data Broker
The concept behind MSI is the synchronized data broker. There are many connected software systems that posses state data that changes over the life of that system. In the case where these systems need to exchange this changing data with other systems and the other systems will exhibit the effects of this data on their own state, the synchronization of this data may need to be managed.
Historically the management of this data has been as simple as tagging it with the time of its release. If there is any conflict in the data the most recent version of the data is used. If the data is late an extrapolation can potentially be used. In SQL relational databases transactions and locking are used to ensure data integrity. Most data brokering services offer little or no sychronization, only delivery.
MSI Setup and Use
The MSI uses a XML stream through a direct socket connection for communications. This enables the MSI to be used from any programming language that can use sockets (C, C++, Java, Ada, Lisp, Perl, etc.). Also, the MSI was written with cross-platform libraries that make it portable to all the major OS platforms (Linux, Solaris, Mac OS X, Microsoft Windows, IRIX, HPUX, etc.).
The MSI is a single executable file and is distributed with example code for the simulator/federate side interface.
MSI Time Synchronization
The MSI time synchronizer can mix unconstrained with time constrained simulations. Each constrained simulation reports the time of the next event that will occur in that simulation/federate. This time may be artificially inflated to cause loose synchronization (less overhead but less guarantee of accuracy). The simulations/federates will advance to the announced time.
MSI Data Synchronization
The MSI implements a publish/subscribe data broker. The MSI is presently not validating, therefore it does not require a separate data format specification (like the HLA FOM). When data format validation is implemented, it will be an optional feature and not written in Lisp. This greatly reduces MSIs setup time. Also, not being locked to a predetermined data format allows for dynamic data types.
There are five commands associated with the MSI data broker: publish, subscribe, update, unsubscribe, destroy (destroy is not implemented yet). Simulations/federates may subscribe to object names in addition to object types. This allows simulations to subscribe to specific objects of a type without needing to receive updates of all objects of that type. The update command is both an incoming and outgoing command. When a simulation/federate receives an update command, it is expected to reflect the new values of that object.
The MSI has a very flexible publish and subscribe system. A federate may subscribe to an object type or an object name. In addition a federate may specify particular attributes of an object or object type. For example, if an object has attributes name, x, y, and z, a federate that only considers two dimensions may choose to subscribe only to name, x, and y.
The MSI also supports systems of systems and object hierarchy in simulations. A publishing federate may designate a parent object. Subscribers may then subscribe to the objects children.
MSI Messaging
The MSI allows simulations/federates to send messages (interactions in HLA) to each other. These messages can contain multiple attributes and be multicast to a specific group of simulations.
Recently Added Features
Removed external library dependencies to improve the portability and fragility of the MSI.
Added a better client library.
Improved documentation.
Enhancements:
- An XML parsing bug in the utilities library was fixed.
- The socket library was enhanced with more protocols, Win32 tricks, and the ability to key off of addresses as well as names.
- The --wait-for command line argument was added.
- Several internal bugs were fixed.
- More of the client library and the CSIM interface were flushed out.
- All standard functionality was tested.

Keyword Market Value Analyzer allows you to compile a database a keywords based on a particular keyword subject, and to compare their popularity with the highest amount advertisers are willing to pay to advertise for the keyword.
The result of Keyword Market Value Analyzer is a really good idea about how much money-making potential there is for the keyword.
Main features:
- Keyword Market Value Analyzer is easy to install. Just unzip, install the database tables and upload.
- Create different keyword subject groups. The groups share the same keyword data, so you can leverage the research youve done for one keyword group for another, related keyword group.
- Easily browse keywords based on market value, highest bid, or most popular.
- Makes keyword market value research as easy as it can be!
