Free platform independent software for linux

The SigmaPi Neural Network Simulator is designed for time-series processing and neural network research on Unix/X11. Since version 0.5, it uses the LSTM neuron model, the RTRL training algorithm and a heuristic learning rate adaptation based on local update sign-changes. It is GPL-covered, so you can use it for free (read the license for more information)

The current version runs with the Trolltech QT 3.x API and is therefore platform-independent.

SigmaPi is no end-user software. It allows the user to change every possible network parameter, and it wont tell you whether a setting is nonsense or not.

The Business Integration Engine (BIE) is offered under a dual licensing approach and is the industrys first open source offering. BIE is designed to help organizations exchange data created in different applications on various platforms with partners, suppliers, and customers in order to streamline processes and improve efficiency.

BIE is a cost-effective, lightweight integration solution that provides many advantages over existing integration approaches and is evolving into a Service-Oriented Integration tool.

Created originally for manufacturers with diverse back-end systems and large, fragmented distribution networks, BIE provides integration capabilities in environments where other solutions would be cost-prohibitive or inefficient due to antiquated trading partner systems, lack of industry standards, and/or extensive requirements.

Because BIE is platform-independent, many legacy systems can be leveraged "as is." BIE is flexible, extendible and scalable, making it possible to integrate a wide variety of applications - even other integration utilities - quickly and cost-effectively.

It competes in the same space as applications like Microsoft BizTalk except that it is truly cross-platform since it written in Java.

The concept is similar to an internet browser. But it is intended for the use in industrial process visualization.
It is based on Qt http://www.trolltech.com which is a platform independent GUI toolkit. ProcessViewBrowser is platform independent, because only posix calls and Qt are used. ProcessViewBrowser runs on Linux/Unix, OpenVMS and Windows.
The browser can display nearly all standard Qt widgets (labels, buttons, editfields, comboboxes, ...) and other widgets for bmp images, diagram widgets for displaying xy-graphs, OpenGL and VTK.
The widgets can be arranged on your masks. You can specify the position and size of the widgets.You can place one widget on top of another widget. I have seen many process visualization systems, which define their masks in the clients (I think this is not the right way to go).
Instead of this, the masks in ProcessViewBrowser are defined in the appropriate process computer itself. The user can jump from one process computer to the other and see all masks. When masks are updated nothing has to be done in the clients.

UnNaTuRaL is a platform-independent role-playing engine. It was named for the "UnNaTuRaL laws" of infinite individual user-created worlds.
These detailed worlds are built entirely from resource files (simple, easy-to-read text-files) which control the language of the user interface, the terrain of the world, and its creatures, conflicts, and encounters.
UnNaTuRaL: The Worlds
UnNaTuRaL worlds are built from simple text files. The example world "one" is included in the game. Open its files in an editor and see what it takes to be a minor god.
If you play god, let us play too. Send us your world and well post it here for all to download. Well set up a rating system so download stats are available. Play god ...
UnNaTuRaL: The Gods
UnNaTuRaL is based on the UnNaTuRaL laws of its Python classes. Read the code and see what makes it tick. If you like what you see, maybe you should join the Pantheon.
Some one has to make the rules. It might as well be you.
Enhancements:
- This release adds world two by TinPenguin.
- The deprecated whrandom has been changed to random.

The purpose of the SurakWare Base Library (SWL/libswl) is to serve as a platform independent development framework for C++ and QPascal.
The SWL includes both thin layers over functionality exposed by the Linux and Windows operating systems as well as higher level classes for many purposes. Save for a few exceptions, the SWL is completely indpedenent from the STL and the C/C++ runtime library.
Platform independence has been achieved by encapsulating OS-specific implementation details in a number of SWL classes. There should never be a need to use "#ifdef"s to distinguish between platforms.
Enhancements:
- Some memory and file descriptor leaks were fixed.
- Some buffer indexing problems were fixed. I/O dispatcher problems on high load notifies were fixed.
- TFile::directory() was fixed.
- TEventManagers add/remove operation logic was improved.
- TNullEnumerator::moveNext() was fixed so that it returns false rather than throwing an exception.
- Some 64-bit vs. 32-bit compilation fixes were made.
- TStream::readTimeout and writeTimeout were backported from trunk to 0.4 (and thus introduced EIOTimeout exception).
- General improvements were made to TArgumentEvaluator and TAnsiColor.
- General code cleanup was done.
