Free multi tier 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.

An open Quality of Service Architecture is an open architecture for the provisioning of Quality of Service related functionality into the Linux kernel.
The project features a flexible, portable and lightweight software architecture for supporting QoS related services on the top of a general-purpose operating system as Linux. The architecture is well founded on formal scheduling analysis and control theoretical results.
At the core of the software there is an adaptive Resource Reservation layer that is capable of dynamically adapting the CPU allocation for QoS aware applications based on its run-time requirements.
As it is highlighted by the AQuoSA architecture, the project is mainly composed of two components:
- the QoS Res module, for which you can browse online the kernel, application and internal APIs
- the QoS Mgr module, for which you can browse online the kernel, application and internal APIs
Enhancements:
- Some bug fixed

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.

Multi Gnome Terminal is an enhanced version of gnome-terminal, with many powerful new features and extensions. The most notable enhancement is the ability to run multiple terminals within the same window.
Each terminal may be accessed by its "tab", through keyboard shortcuts, or menu selections. Inactive terminals provide an alert when the buffer changes by changing the color of the tab labels.
Other enhancements include a toolbar, a buttonbar, flexible command options to launch new terminals, tabs, and shells from either the GUI or command line, customizable key bindings for MGT functions and other uses, font shadowing, the ability to "split" terminals so that each window can simultaneously multiple terminals, the ability to "view" or "bond" terminals with other terminals, and various other improvements
Main features:
- Multiple terminals may be opened within the same Window.
- Each terminal Window is "Tabbed" for easy navigation.
- The terminal Window may be "split" vertically and/or horizontally. And also unsplit, or the split terminal can be moved to its own "Tab", or even another Window.
- Terminals may be "bonded" so that the output of a command in one terminal is echoed to all the "bonded" terminals.
- Terminals may be moved from one Multi Gnome Terminal Window to another.
- Notification that an inactive terminal buffer has changed, or is in the process of changing, via colors on Tab labels.
- Extensive keyboard shortcuts for most Multi Gnome Terminal features, and configurable key bindings for these features and other uses.
- Shading, tinting and psuedo-transparency of the Multi Gnome Terminal Window background.
- Gamma corrrection and contrast controls for background pixmaps.
- Configurable "Commands" for initializing new terminals, accessible from within the Multi Gnome Terminal GUI interface, or as command line options.
- Adds a Toolbar and Buttonbar, which can be disabled like the other GUI components. The Toolbar can be repositioned too.
- Search the scrollback buffer.
- Font "shadowing" for better contrast on transparent or pixmapped backgrounds.
- Improved terminal emulation capabilities, including support for VT52.
- Improved support for launching URLs direct from the terminal Window.
- A flexible command line for creating new Windows and Tabs.
- Bold fonts can be a different font, and different color.
- Support for pseudo-graphics characters (like xterm).
- Greatly improved Class handling (configuration profiles) with many available configuration options.

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, and lightweight software architecture for supporting QoS-related services on top of a general-purpose operating system as Linux.

The architecture is well founded on formal scheduling analysis and control theoretical results. 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.

Multi-Protocol Remote Login provides a middleware allowing SSH, telnet, and local logins from the login: prompt.
MPRL is a middleware application between a *getty program and SSH, telnet, and other such remote-login protocols. It allows a user at a Linux terminal to log into other systems without needing a valid local user-id. It currently supports telnet, ssh, and /bin/login.
It syntax follows the [protocol:]user[@host][:port] fashion.
These are valid logins:
- buanzo - Normal local login: /bin/login gets called.
- buanzo@linux.org.ar - SSH protocol by default: /usr/bin/ssh gets called
- ssh:buanzo@webserver.algo.net
