PIX Logging Architecture [PLA] is a project allowing for correlation of Cisco PIX Firewall Traffic and IDS Logs.
Centralization of the logs is provided using a MySQL database, supported by a Web-based frontend for Log Viewing, Searching, and Event Management.
PLA is completely coded in the Perl programming language, and uses various Perl modules including Perl::DBI and
Perl::CGI.
Main features:
- Parsing of Cisco PIX Syslog Messages
- Centralized MySQL Database Logging
- Multiple Firewall Support
- Web-based frontend for:
- Cisco PIX Traffic Logs
- Cisco PIX IDS Logs
- Searching Cisco PIX Traffic and IDS Logs
- Cisco PIX Traffic and IDS Statistics
- Event Management (Incident Management)

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).

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.

Sofa is a media center aimed at easy usage for GNOME.
Sofa is a media center aimed at easy usage, minimal configuration and total integration with the Gnome desktop environment and existing multimedia applications. The project has a modular architecture. Two modules exists as of now: Videoplayer and Rhythmbox integration.
Supported Media
- Music (file types supported by Rhythmbox)
- Local video files (file types supported by GStreamer)

Midgard Components Framework (also called MidCOM) is an advanced component architecture which extends the Midgard Web content management framework. It provides mechanisms for building a Web site using components without much need for writing code to glue all this together.
The administration site gets built automatically by using those components. Goodies like a caching engine and subrequests make site building even easier.
Enhancements:
- Full multilingual content support, performance enhancements, and support for Midgard builds that have the legacy API disabled were added.

Filaments is a library package that can be used to create architecture-independent parallel programs---that is, programs that are portable efficient across vastly different parallel machines. Filaments project virtualizes the underlying machine in terms of the number of processors and the interconnection.
This simplifies parallel program design in two ways. First, programs can be written (or generated) with the focus on the parallelism inherent in the application, not the architecture. Second, programs can be written that use familiar shared-variable communication.
Furthermore, Filaments uses a carefully designed API along with machine-specific runtime libraries and preprocessing that allow programs to run unchanged on both shared- and distributed-memory machines. Most importantly, applications programmed in Filaments run efficiently, achieving a speedup of over 4 on 8 processors or nodes in almost all tests that have been performed.
Platforms supported
Currently the following (homogeneous) architecture/OS combinations are supported:
- cluster of Sparc/Solaris
- cluster of X86/Solaris
- cluster of X86/Linux, kernel version 2.0.23 and above (older versions may work, but - have not been tested)
- multiprocessor SGI/Irix
- multiprocessor Sparc/Solaris
Note that Filaments does not run on heterogeneous platforms.
