Free cloud computing software for linux

Cloud Wiki is a wiki engine written in Python and backed by Sqlite. Cloud Wiki provides user authentication, powerful command line administration facilities, and a concise, efficient Web interface.
Main features:
- Flexible user authentication system. See An Argument Against Anonymous Wikis for an explanation why Cloud Wiki supports user authentication.
- Implementation of C2 Wikis fundamental Wiki Principles
- Extremely fast SQLite database used for node storage, caching generated content html, content changes and dependency information.
- Long running web server process, instead of a slow loading CGI. Designed to run well behind a reverse proxy.
- Minimalist markup language designed with an emphasis on having just enough features to be useful, but not so many that new users are intimidated. All linking is done with brace-enclosed free links, for example.
- Modular user authentication system.
- Powerful command line node and server manipulation tools for easy administration.
- An interface to view change/replacements to a node in the past three days.
- Added Nodes gateway to list all nodes added to the wiki in the past three days.
- Changed Nodes gateway to list all nodes changed on the wiki in the past three days.
- Generated content is automatically valid, strict XHTML 1.0.
- Wikis may be exported to static HTML files; our Sourceforge website is produced this way from our test wiki.

AmarokCloud is a script generates a "tagcloud" from your Amarok database by score or times played.

Usage: Execute to use the (crappy) GUI or via commandline:

amarokcloud.py /path/to/collection.db datatype scoringtype

Your collection is usually at /home/user/.kde/share/apps/amarok/collection.db

Datatype is the data which you want to generate the cloud from. Its either genre or artist

Scoringtype decides how to calculate the score

The GUI is horrible, I know, but it does its job and I dont have time to learn PyQt

Ch is an embeddable C/C++ interpreter for cross-platform scripting, shell programming, 2D/3D plotting, numerical computing, and embedded scripting. C/Ch/C++ allow users to use one language, anywhere and everywhere, for any programming tasks. Ch is the solution for:
- Embedded Scripting
- Enterprise
- Academic
- Plotting and Numerical Computing
C++ is C plus plus minus. Ch is C plus (Ch = C+). Ch is a C interpreter. Ch is C with classes and high-level extensions. Ch is a superset of C. Note that C++ is no longer a superset of C. For example, VLA and IEEE floating-point arithmetic in C are not supported in C++.
C is for low-level system programming and embedded systems; C++ for large-scale projects. Ch is optimal for platform-independent scripting in numerical computing and visualization, rapid application development, Web programming and plotting, embedded scripting, shell programming and integration with legacy systems.
Like C++, Ch is designed to be a superset of C, which means a C program can run in Ch without modification. Unlike C++ which is designed for serious professional programmers (elite), Ch is designed for both novice beginners with no computer experience (average Joe and John) as well as experienced programmers.

Aero AIO: Folding@Home is a plugin for Aero AIO to monitor your Folding@Home client. It comes with a simple configuration dialog to set the update interval and client path.

It was inspired by navyrains folding-karamba theme.

Folding@Home is a distributed computing project to understand protein folding, misfolding and related diseases (http://folding.stanford.edu).

Compute Portal Project is a portal project to produce a web based front end to a compute resource, such as a cluster, using PHP, mysql, and apache.
The intent is to allow non-programmers to use complex programs through an intuitive interface.
Enhancements:
- This is the third attempt to create a working release with an install script.
- The last two releases were plagued with copy and paste errors.
- This release is strictly a bugfix release that has been tested in a production environment.
- There may still be residual problems from the 0.8.8 to 0.8.9 transition that included the first install script and moved several directory locations.
- Please give this release a try.

CCFlauncher is the meta-tool for starting and joining a CCF collaborative computing session. With CCFlauncher you can invite your colleagues/friends to join you in a shared X windows virtual desktop with multiparty audio conferencing, white board, and file sharing in just a few mouse clicks. In this setting, participants interact with each other, simultaneously access and operate computer applications, refer to global data repositories or archives, collectively create and manipulate documents or other artifacts, perform computational transformations, and conduct a number of other activities via telepresence. Research issues addressed in this project include problem solving environments and methodologies for laboratory and instrument-based scientific disciplines, and computer science issues in heterogeneous distributed systems. New approaches are being investigated and developed for fast multiway communication, robust geographically distributed data management methodologies, high-performance computational transforms inlined within collaboration sessions, and related auxiliary issues such as active documents, security, archival storage, and experiment management and control.

The main goal of CCF is to enable the construction of efficient and flexible collaborations. Although we expect that CCF will be useful in a number of scenarios, a guiding principle in its design was to identify and meet the needs of natural science investigators with a diverse set of computing, instrument interfacing, and collaboration requirements. Thus, the primary target domain for CCF is collaborative research in chemistry, physics, and biochemistry, and closely related areas. Research methodology in laboratory and instrument based sciences is increasingly dependent upon computation, interaction, visualization, and data storage/retrieval. The CCF project is investigating and developing innovative enabling technologies to support collaborative, distributed, computer-based problem solving in the natural sciences. The goal is to evolve a virtual environment for distributed computing that integrally supports human AV communication, high performance heterogeneous computing, and distributed data management facilities. Computational transforms, instrument interfacing, data referral, visualization, and collaborative work in chemistry, physics, and biomedical fields will guide the development of methodologies and software tools to facilitate collaborative research.

Search And Rescue project is an air rescue flight simulator. The player pilots rescue helicopters to rescue victims in various situations of distress.

Search and Rescue is a helicopter based air rescue flight simulator. It employs a simple flight dynamics engine that is targetted towards the "average" player. It is not designed to be a cutting-edge realistic simulator, but rather a flexable game that everyone can play and enjoy.

The history of the development of this game goes back to 1997, when Search and Rescue was created as an explorative to design for more complex 3D games using the OpenGL graphics library. Much of the effort in the development of this game came from Wolfpack Entertainment and many dedicated contributors (see credits below).

This game was ported to Windows early on in its development to ensure the portability of its graphics code. However the Win32 version lacked certain features due to differences in Windows design of its graphic, sound, and controller implementation.

The flight dynamics engine (FDE) features helicopter, aircraft, and tilt-rotor aircraft flight dynamics models (FDMs). It uses source-centered (as opposed to world-centered) mathimatical equations to simulate movement which mimicks but does not fundimentally follow standard physics equations. This simplifies the "flyability" of the aircrafts at a slight cost of realisim and lightens processor load.

The 3D visual models of the aircrafts and objects were created by a program called Vertex 3D, an OpenGL modeller designed to create 3D visual models that are optimized for OpenGL.

Each scene is a finite sized flat world, separated vertically by cloud layer(s) and centered at the origin with an artificial longitude and latitude offset applied to displayed positions.
