Free what is architecture software for linux

Af-Arch is being developed to give GNU/Linux a new middle-ware for building enterprise managing applications, typically database oriented.
Af-Arch is a complete set of libraries and tools which allows to develop distribuited system especially designed to face problems about bussiness applications.
Actually, Af-Arch is really robust and stable, having systems installed on many environments. Af-Arch, at this moment, runs on GNU/Linux and Microsoft Windows.
AF Architectures license schema is based on GPL and LGPL, allowing you to develop not only open source applications but also comercial applications without any royalty or fee.
Af-Arch is a strongly documented project, which is proved to work. Af-Arch keeps on evolving and growing its feature list allways keeping in mind productivity.
Enhancements:
- A new major stable release have come with many interesting features, library dependencies news, new API to make life easy and a bunch of work to make the library to be memory efficient.
- Af-Arch no longer depends on GDA library (http://www.gnome-db.org). Now AfGs, server side support for Af-Arch, includes built-in database abstraction support, implemented to fit better with the Af-Arch framework. For more details check the "libafgs" log below.
- Af-Arch platform now support three new return types: AfDalNodeData, AfDalStringData and AfDalDecimalData, which allows services to return a module node, a plain string and a decimal value as a result for the invocation.
- Af-Arch now support a new formal parameter service AfDalSetOf which implements set of items to be sent while the service is invoked.
- af-gen tool now support defining string literals that are separated by "+" sign, making it easy to write long SQL sentences.
- af-gen tool now allow to generate type definitions that could extend, making it possible to create a class hierarchy for types to be returned by services.
- libafdal core library now implements a better error reporting mechanism which allows to receive all errors generated while performing invocation at the reply process code.
- New reserved services have been added: element_peek_reference which allows to get the node associated to a module which is relationed through the 0..1 link.

Growler is a C++-based distributed object and event architecture. The software is written in C++, and supports serialization of C++ objects as part of its Remote Method Invocation, Event Channels, and in its Interface Definition Language.

Its primary application has been in support of interactive, distributed and collaborative visualization, computational steering, and concurrent visualization.

Adaptive Quality of Service Architecture (AQuoSA) is an open architecture for the provisioning of adaptive Quality of Service functionality into the Linux kernel. The project features a flexible, portable, lightweight and open architecture for supporting soft real-time applications with facilities related to timing guarantees and QoS, on the top of a general-purpose operating system as Linux.
At the core of the architecture there is an adaptive resource reservation layer that is capable of dynamically adapting the CPU allocation for QoS aware applications based on their run-time requirements.
Timing guarantees are provided through an in-kernel reservation based process scheduler, whose services are exposed to applications through a well-designed API.
A supervisor performs admission control, so that admitting into the system new applications with timing guarantees does not affect the timing guarantees of already admitted applications. Also, it takes care of guaranteeing appropriate security policies in the assignment of timing guarantees to users and user groups, as configured by the system administrator.
A feedback-based QoS control layer may be optionally used by applications who want to keep their timing guarantees by using a CPU allocation that is continuously adapted according to their actual needs. This leaverages the programmer, within certain limits, to hard-code any particular reservation amount within the application, because the best allocation is found out automatically at run-time. Also, this enhances the possibilities for the system to host additional QoS controlled applications. The available control algorithms are well founded on formal scheduling models and control theoretical results.
Enhancements:
- This release introduces a couple of flags useful when creating servers. If QOS_F_PERSISTENT is enabled, a server is allowed to exist beyond detach of the last task. If QOS_F_SOFT is enabled, a server tasks are scheduled by the Linux default scheduler/policy, when outside of the server reservation.
- Also, various stability issues in destroying servers have been fixed, also thanks to a new release of the generic scheduler patch for the Linux kernel (gs-2.2).

Archimedes is an Open CAD for architects.

Archimedes is a Computer Aided Design (CAD) program developed side by side with architecture offices in order to fulfill all their needs.

This way, we hope to develop software better suited for architects than the currently widely used AutoCAD.

IRC Collective software contains a parser, with a modular architecture that makes it flexible in the way it can process input and handle output. The output of the parser is primarily used to add to an SQL database that can in turn be queried by, e.g., a Web application (also provided).

The parser can be extended by defining new input formats and output handlers. It can help you stay up to date on the IRC channels that you visit regularly. You can write your own applications on top of the SQL database. You can search past conversations using the Web interface (results will be paged).

Hamachi is a zero-configuration virtual networking system featuring an NAT-to-NAT traversal, open security architecture, and multi-platform client software.
Hamachi is a zero-configuration virtual private networking application with an open security architecture and NAT-to-NAT traversal capabilities.
Hamachi is the first application to mix seemingly unrelated networking technologies in one powerful package to deliver an unprecedented level of peer-to-peer connectivity.
Hamachi is secure. All Hamachi communications are encrypted and authenticated with industry-standard algorithms and protocols. Nobody will be able to see what two Hamachi peers are talking about. Not even us.
However what is equally important - Hamachi security architecture is completely open meaning that its detailed description is available for the review to anyone interested.
Installation:
Hamachi Linux client comes as a single executable binary (hamachi) compiled for the platform of your choice. This binary includes the daemon, the control application and the setup utility.
To install hamachi in /usr/bin run the following command from under the root account
make install
Once installed you must run tuncfg daemon with root privileges -
sudo /sbin/tuncfg
or if you dont have sudo -
su - ; /sbin/tuncfg; exit
Hamachi requires one time initialization (per Linux user account). This step generates cryptographic key pair and creates ~/.hamachi directory where Hamachi stores the keys, the configuration and the state. To perform this initialization run
./hamachi-init
Enhancements:
- Fixed a bug causing the daemon to segfault in the event of some peer going offline.

PatientOS is a free clinical information management system designed for hospitals and healthcare practitioners.

PatientOS project is for physicians, nursing, pharmacy, the laboratory and eventually all hospital departments. An extensive sofware architecture has been designed to create the highest quality system.

DebUpdate Applet is a GNOME2 panel applet that periodically checks for Debian package updates from a Debian Update Server.
At the interval you specify, the applet will query a Debian Update Server(See the DUS link below) for updated and new packages for your Debian system(you can over-ride the release and architecture if you wish). When new updates are available the applets panel icon,a Debian "swirl", will rotate.
Configurable options include:
- Update interval
- Check for new packages?
- Check for upgradable packages?
- Check for updated packages?
- Colorize list?
- Debian release(autodetect, stable, testing, and unstable)
- Debian architecture(autodetect, sparc,i386,m68k, etc...)
- Server to query
