Free experienced software for linux

CRUX is a lightweight, i686-optimized Linux distribution targeted at experienced Linux users.
The primary focus of this distribution is "keep it simple", which is reflected in a simple tar.gz-based package system, BSD-style initscripts, and a relatively small collection of trimmed packages.
The secondary focus is utilization of new Linux features and recent tools and libraries. CRUX also has a ports system which makes it easy to install and upgrade applications.
There are many Linux distributions out there these days, so what makes this distribution any better than the others? Well, its all about taste really. I can give you a hint about my taste, and perhaps we share the same taste, or we dont.
First of all, I want a distribution made with simplicity in mind from beginning to end. Further, I want my packages up-to-date, not the latest bleeding-edge-alpha version, but the latest stable version. I want to easily create new and update old packages (updating a package in CRUX is often just a matter of typing pkgmk -d -u).
I want packages optimized for my processor (think -march=i686). I dont want my filesystem cluttered with files I never use (think /usr/doc/*, etc). If I need more information about a specific program, other than information found on the man-page, Ill find it on the net. And finally, I want to use new features offered by recent Linux kernels (think devfs, reiserfs, ext3fs, etc).
If you are a somewhat experienced Linux user that wants a clean and solid Linux distribution as the foundation of your installation, prefers editing configuration files with an editor to using a GUI, and doesnt hesitate to download and compile programs yourself, then this distribution might suit you well.
Enhancements:
- CRUX 2.3 has been released." Whats new? "CRUX 2.3 includes glibc 2.5 and GCC 4.1.2; the monolithic x11 package has been replaced by the new modular X.Org distribution - as the results of this update, crux.nu now hosts a dedicated xorg ports repository, installed by default; the netkit-base port has been replaced by inetd and iana-etc; by popular request we included iproute2 and iputils in the core collection.

Brutus is an Open Source connector for Exchange 5.5, 2000 and 2003, to put it short. Our aim is to scratch one of the most annoying itches that the Open Source community have endured. This particular itch has been experienced for almost a decade.
The problem that we are addressing is the problem of platform independent access for client applications to Microsoft Exchange from version 5.5 onwards.
Our solution to this problem will enable a feature-by-feature compatible Microsoft Outlook replacement for Linux, Microsoft Windows, the BSDs or almost any other platform.
How do we do it?
We have developed a CORBA based framework on top of the Messaging Application Programming Interface commonly known as MAPI.
Our development framework is offering client applications MAPI based access to any MS Exchange server from version 5.5 onwards. We believe that we are providing the Open Source community with a development framework that are superior to any other approach.
Our solution is distributed under the GNU General Public License (commonly known as the "GPL") or a commercial license.
Why do we do it?
We feel that there is a strong customer need for a non-Microsoft client application with full Exchange integration that is feature-by-feature comparable with Microsoft Outlook.
The only technically feasible way to achieve this level of integration is to build a client access framework on top of MAPI.
Out strategy is therefore to provide this framework to the Open Source community free of charge under the GPL and to the any commercial entity under a commercial license.
Enhancements:
- Support for OpenSUSE 10.2 was added.
- brutus-keyring is now used instead of gnome-keyring.
- A thread storm when updating the folder summary is now avoided.

eZ publish is a popular open source content management system and development framework. eZ publish project is distributed, developed and supported by eZ systems. eZ systems is a commercial company, founded by experienced and open-minded people. The company builds its business by providing services around the eZ publish system. For more information about eZ systems, read the "What is eZ systems?" section.
eZ publish allows the development of highly professional and customized internet solutions and dynamic web applications. It can be used to build anything from a personal homepage to a multinational corporate website with role based multiuser access, online shopping, discussion forums and other advanced functionality. In addition, because of its nature of openness, eZ publish can be easily plugged into, communicate and coexist with existing IT-solutions.
eZ publish comes with a wide range of advanced built-in features, which make it possible to develop professional, complex, secure and reliable solutions within a short amount of time. In addition to the built-in features, the system allows for extensions and custom modifications in almost any direction. Unlike other content management systems, eZ publish delivers a flexible, generic solution with very few limitations. In other words, this is a scalable and dynamic system that companies and organizations can grow with.
eZ publish is platform independent. It can be used on Windows and several UNIX variants such as OS X, Linux, FreeBSD, Solaris, IRIX, etc. In addition, eZ publish is also database independent; if a specific database isnt supported, it is possible to write a driver without modifying any kernel code.
eZ publish is open software, supporting open standards. The software is constructed following strict development processes in order to ensure high technical quality and usability.
eZ publish is dual licensed. There is a GPL (General Public License) and a professional license. Using the GPL license, people can build their own open source applications and thereby contribute to the development of free and open software. The professional license allows companies to make and sell commercial software that is developed using and/or built upon the eZ publish system.
Enhancements:
- Several bugfixes and enhancements.
- The command line package tool ezpm.php has been updated: list, import, and install commands have been changed to match the admin interface functionality.
- The ezinstallscript and ezextension items are supported by the add command. ezpm is allowed to set the vendor.
- Enhancement #010347 (progress output for correctxmltext.php and updatetypedrelation.php) has been implemented.

RDVIS tool helps programmers pin-point the sources of cache misses and poor temporal locality in their source code.
The visualization often directs the experienced programmer towards the necessary program transformations within a few minutes.
The tool consists of two parts: a GUI that visualizes the low temporal locality patterns, and a patched GCC compiler to extract the low-locality patterns from programs.
Enhancements:
- Improved cluster window interaction: allows selection of individual reference pairs, allows the height of the basic block vector to be proportional to its weight, and has a number of different sort options for the basic block vectors.
