Free mature software for linux

TurboGears project is based on the agile, mature, cross-platform, well-documented, easy and fun Python programming language.
Python makes it super simple to get started with TurboGears, whether youre running Windows, Linux, Mac OS X or even a cell phone. OK, so youre probably not going to want to run a web server on your cell phone.
Any way you slice it, youll be amazed how quickly you get started!
Installation:
Even though you dont have Easy Install yet, you can still take advantage of it. Instead of one-command installation, it will be two-step installation. And, youll have Easy Install for the next update!
The instructions below will install into the primary system locations for Python modules. On many systems, this requires superuser access. So, performing the installation below will require you to enter your password. If your system does not have sudo installed or configured properly, you can su to the superuser account and then run the command.
Note that on some Linux systems (Ubuntu, for example), you may need to install a "python-dev" packages in order for everything to compile correctly.
- Download the ez_setup.py script.
- Run sudo python ez_setup.py -f http://www.turbogears.org/download/index.html --script-dir /usr/local/bin TurboGears
Enhancements:
- Much better on-line documentation was provided.
- Internationalization is now also available for the JavaScript files.
- When using SAprovider for identity management, passwords are now encrypted on the fly if a identity.saprovider.encryption_algorithm is set to md5 or sha1 in app.conf.
- An alternative quick-start model that uses Elixir (using -e switch) is proposed.
- A similar one will become the default in 1.1.

Excalibur is an open source software project of The Apache Software Foundation. Our primary product is a lightweight, embeddable Inversion of Control container named Fortress that is written in java.

Inversion of control, also known as the hollywood principle ("dont call us, well call you"), is a simple but powerful concept. The idea is that we dont "wire up" all the pieces that make up an application (the "components") by writing lots of this-component-uses-that-one-like-so code, nor do we use some kind of lookup directory (like JNDI, for example) where each component decides what components to interact with itself. Instead, we instruct a smart piece of software, the container, to tell the components how to interact.

Fortress (and also its predecessor, "ECM") is such a container. It is lightweight, by which we mean that it doesnt need a lot of resources, take a lot of disk or memory, or impose all sorts of demands on its environment. Fortress is also embeddable, by which we mean that you can use fortress inside just about every java environment. More concretely, you can use it as the basis of a large standalone development platform (like the Keel project), at the core of a servlet-based web application (like Cocoon) or even as the basis of a GUI application (like GuiApp).

Fortress knows how to manage components that have been developed using a rigid lifecycle contract called Avalon-Framework. In the next upcoming release, fortress will also be able to manage ordinary javabeans, and support for other kinds of Inversion of Control are planned.

Besides providing fortress, excalibur also provides a small library of very useful components. We also distribute some of the libraries used to build fortress (and some other containers) seperately. This selection of libraries is called containerkit.

So why is excalibur an interesting project?

Heres a few partial answers.

good code. Code that comes from the mature avalon project (everything that used to be branded as "Avalon Excalibur" and "Avalon Fortress"). This includes two lightweight Inversion of Control containers. One of these powers, among other things, Cocoon. The other ("fortress") is the basis of projects like Keel. Excalibur also includes powerful and mature reusable "components" and "libraries", handling tasks ranging from thread management to component pooling to (URI-and-similar-) source resolving.

smart developers. Most of these people are or have been active in the avalon project in various roles. Several of them are apache members. Together they have loads and loads experience under their belts related to inversion of control development. In fact, Im confident to say this list includes some of the biggest experts on inversion-of-control-style container development.

exciting community. Several open source and commercial projects (both at apache and elsewhere) depend on and contribute to the excalibur project. A strong team of enthousiastic developers (with strong ties to several other projects in the same problem domain) has various big and small plans with excalibur. One of the leading open source organisations in the world, The Apache Software Foundation, is hosting the project, providing insight, advice, infrastructure, legal backing, a time- and battle-proven development process, and much more.

WallFire is a very general and modular firewalling application based on Netfilter or any kind of low-level framework.
It will enable to manage every aspect of a firewall administration, from configuration to monitoring, intrusion detection, etc...
WallFire will provide command line and interactive tools as well as X Window or Web front-ends.
WallFire is "libre" (free as a speech, in English) software. It is mainly written in C++ and is intended to run on every *nix system.
WallFire is a package that is composed of:
a server side:
wfpolicyd, a daemon which can run on any host and centralises the rules and policy management
wfcommitd, a daemon which runs on the firewall(s) itself and commits the firewalling rules, whatever platform it is running on and whatever tools are available on the latter.
So you will need to run a wfcommitd daemon on each firewall, but only one wfpolicyd for a whole site.
a client side:
some libraries (for example wfnetobjs) on which every operation relies
wfconvert, the tool which imports/translates rules from/to any supported firewalling language
wflogs, the log analysis and reporting tool
wfadmin, the administration shell tool
xwfadmin, the X (Qt) administration front-end, which is useful, but not compulsory
webfire, the Web administration interface (in PHP).
Of course, client and server parts can (should?) be run on different hosts. All communications will be authentificated and encrypted (via SSL). Every data (network objects, rules, logs) will be importable/exportable in XML.
So far, the things that have been implemented are: some libraries (wfnetobjs for example), the wfconvert (which is quite functionnal now) and wflogs (which is mature and fully functionnal) commands.
Note that wfconvert and wflogs can be used locally, independantly of other WallFire tools.
Enhancements:
- Improved matching of netfilter and ipfilter input modules.
- Added support for Cisco FWSM (PIX).
- Improved netfilter parsing.
- Compilation fixes for *BSD.
- Added wflogs.dtd.
- Added wfchkintegrity tool, which enables to monitor changes in the firewalling configuration.

TunesBrowser project is a simple music player, capable of playing music found on iTunes shares.
TunesBrowser can connect to the latest iTunes applications (as of April 29 2004) and is implemented on top of libopendaap.
TunesBrowsers interface is quite similar to that of iTunes. TunesBrowser was written with the purpose of being a prototype front-end for libopendaap. I intend to integrate libopendaap with other, more mature, players.
Main features:
- Play mp3s off other computers running iTunes
- Discovery of hosts over Rendezvous.

Snow Path Formation Simulator is a program that models the process of people forming very distinct, and yet not always altogether logical looking, paths in the snow as they walk across open spaces.

The evolving condition of the snow is displayed graphically. This project may eventually mature into a screensaver.

eXtended FLAT (XFLAT) is a binary format that supports dynamic shared libraries on MMU-less Linux (uClinux) platforms.
XFLAT is a mature suite of development tools including compiler, dynamic loader, loader, linker and support tools.
Configure and Build Procedure:
1) Run the configure script to instantiate a canned configuration.
see ./configure.sh --help for more information
./configure.sh
2) Source setenv to define environment variables
source ./setenv
3) Patch the kernel
cd xflat/kernel/
./patch_kernel ../../linux-x.x.x
4) Make the toolchain
cd buildroot
make
5) Make the kernel
cd linux-x.x.x
make
Steps 2) and 3) should be performed only once. Steps 1), 4) and 5) should
be repeated to re-build the system.
See also config/ /README for instructions specific to the
selected configuration.
Enhancements:
- Verifed xflat-ld C++ linking support
- Added documentation for the state of C++ in XFLAT
- Fixed spurious prompts for FPU in uClibc build
