Free state of the art software for linux

State Machine Compiler takes a state machine stored in an .sm file and generates the state pattern classes in nine programming languages.
Its features include default transitions, transition arguments, transition guards, push/pop transitions, and Entry/Exit actions. State Machine Compiler requires Java SE 1.4.1 or better.
Enhancements:
- This release cleans up C# and VB.net debug output using System.Diagnostics.Trace.
- It fixes a number of minor bugs.

The Eye Of Horus is a monitoring and alerting tool for computers. Its mainly useful for monitoring network services (eg, HTTP or SMTP servers) and the internal status of Unix servers (eg, load, disk usage, process counts).

In that respect, its a lot like Nagios, but in my opinion its better. It lacks a few features Nagios has, but it is a very simple architecture to which they can easily be added.

Its a flexible thing made from independent modules with well-defined interfaces, making it easy to customise and extend, but out of the box itll monitor your servers and produce a nice HTML summary of their status - OK, the looks need a bit of work, but that will come soon, and it can optionally integrate with the excellent (and I mean excellent) RRDTool to store logs of statistics (response times, number of packages with known security holes, etc) - and link from the status page to nice graphs of the historical behaviour of these statistics.

HOW IT WORKS

The core of the system is horus-check.py, a Python script which reads a configuration file (specified on the command line). The configuration file specifies a list of services - either network services, in which case the host to run the check from and the host to run the check at are specified, or local services, in which case only the host to run the check from need be specified. In either case, if the host to run the check from is not specified, then it defaults to the local host.

The service types reference definitions in a file which is referenced from the configuration file. In the service definitions file, a shell command to check the service is given; this command must output service status in a defined format, as a single-line YAML list. The list must contain, at least, a single-word status (OK, WARNING, FAILURE, or UNKNOWN), then optionally numeric statistics, then optionally a status message. For example:

[OK]
[UNKNOWN]
[OK, { load: 0.5, users: 3 }]
[WARNING, { load: 3, users: 30 }]
[FAILURE, { load: 95, users: 300 }]
[UNKNOWN, { }, Could not find AWK executable]

When a check is to be performed from a remote host, Horus opens an ssh connection to that host. It is assumed that the user horus is run as will have an ssh key set up to enable it to ssh to all such hosts without requiring a password.

Having performed the checks, horus-check.py then:

Reads in the status database named in the configuration file
Updates the status database with the new status of hosts
Computes an overall system status (the worst non-unknown status of any checked service)
Examines the service dependencies, and marks any service whose state is no worse than might be expected (eg, no worse than the worst state of a service it depends upon) are automatically marked as quiet
Computes a list of differences between the old and new status (services added, services removed, services whose status has improved, services whose status has worsened)
If there are any differences, invokes a notification script (named in the configuration file) with them, along with the overall status
Invokes a logging script (named in the configuration file) with the new value of every statistic reported by the service checks; I will soon provide a sample logging script that uses RRDTool to generate nice graphs.

The status database (which is written in YAML, so easily accessible to user scripts) can then be used to generate HTML status report (see status.cgi).

GNOME Art is a frontend for art.gnome.org.

The GNOME Art Collection written in ruby is a collection of tools for managing art from the art.gnome.org website.

GNOME Art is the graphical frontend for art.gnome.org. Backgrounds and all themes can be downloaded and previewed. Backgrounds, icon themes and splash screens can be installed directly.

GNOME Splash Screen Manager is for managing the splash screens of the GNOME desktop.

open Outcast: The Hidden Gate is a free Outcast successor The aim of the open Outcast project is to create a free successor to the commercial action-adventure "Outcast" released in 1999 and developed by Appeal.

Since the official sequel was canceled we decided to create our own using free technology like Crystalspace / CEL since portability and a free license were important to us. We also make sure, that all artist tasks can be done via free programs as well (like 3d art 3dsmax OR Blender, 2d art Photoshop OR Gimp).

Art of Illusion is a free, open source 3D graphics studio.

Art of Illusion combines modelling, animation, texturing and rendering in one application, with advanced features which compare favorably to those found in many commercial programs.

Art of Illusion is written entirely in Java. It should (in theory) work under any Java Virtual Machine (JVM) which is compatible with Suns Java Development Kit (JDK) 1.4 or later.

FastVox project is a state of the art volume rendering API with outstanding image quality and acceleration features that take advantage of todays hardware. These features include GPU, SSE and hand-tuned assembly language optimizations, resulting in one of the fastest implementations available on the market.
FastVox is built on top of OpenGL, the leading industry standard for high performance 3D computer graphics. A new feature of the 2.0 engine are the GLSL-based pixel shaders which perform all volume rendering computations exclusively on the GPU.
A key-feature of FastVox is the clean and simple API. This API enables developers to quickly integrate FastVox into third-party applications.
In contrast to other volume renderers, FastVox also supports features specially suited for use in the medical field. Features like Multiplanar Reformation and Maximum Intensity Projection are supported and made readily accessible through its simple API.
Enhancements:
- This release features hardware-accelerated rendering plugins based on the OpenGL 2.0 GLSL shading language.
- The GPU acceleration is available for volume rendering, ISO surface rendering, maximum-intensity projection, and multiplanar reconstruction.
- In addition, the handling of transfer tables has been facilitated and enhanced to improve the rendering output.

libmysqltemplate project is a very high speed C state machine template library that uses MySQL data for the source of the templates and optionally for name/value pairs.

It is required for the mysqlApache2/mysqlMail2/iDNS family of openisp.net/unixservice.com Web based consoles for clusters and other complex Internet service infrastructure management.
