CUPS provides a portable printing layer for Unix(r)-based operating systems. Common UNIX Printing System has been developed to promote a standard printing solution for all Unix vendors and users.

CUPS provides the System V and Berkeley command line interfaces, and uses the Internet Printing Protocol ("IPP") as the basis for managing print jobs and queues. The Line Printer Daemon (LPD) Server Message Block (SMB), and AppSocket (a.k.a. JetDirect) protocols are also supported with reduced functionality.

CUPS adds network printer browsing and PostScript Printer Description ("PPD") based printing options to support real world printing under UNIX. It includes an image file RIP that supports printing of image files to non-PostScript printers.

A customized version of GNU Ghostscript 7.05 for CUPS called ESP Ghostscript is available separately to support printing of PostScript files within the CUPS driver framework. Sample drivers for Dymo, EPSON, HP, and OKIDATA printers are included that use these filters.

DesktopBSD aims at being a stable and powerful operating system for desktop users.
DesktopBSD combines the stability of FreeBSD, the usability and functionality of KDE and the simplicity of specially developed software to provide a system thats easy to use and install.
The main goal of the DesktopBSD project is to provide a desktop operating system thats easy to use, but still has all the functionality and power of BSD.
In the long term, DesktopBSD wants to build an operating system that meets most requirements desktop users have, like installing software, configuring power management or sharing an internet connection.
To be better able to fulfill this goal, we strongly rely on users that send in feature requests, ideas for improvements or participate in development.
DesktopBSD is free software, which means it is free of charge. Also, if youre a developer and want to find out how DesktopBSD works or modify it to fit your needs, you can download the full source code.
Main features:
Stability
- DesktopBSD is based on FreeBSD, which is one of the most reliable and robust operating systems in the world.
Usability
- The KDE Desktop Environment and specially developed tools provide a maximum of usability to our users. KDE features such as KIO slaves or remote desktop sharing and DesktopBSD features like network profiles, easy mount procedures and many other convenience features make life easier and increase productivity.
Performance
- The development of FreeBSD (and therefore DesktopBSD) is highly focused on performance. The system manages resources efficiently and reacts fast even when many processes are running simultaneously. This also affects networking, so DesktopBSD tries to optimally use the available bandwidth.
Security
- Concerning security, the BSD operating systems are world-class. For example, OpenBSD had only one remote in the default install in more than eight years. DesktopBSD benefits from the work of other BSDs such as OpenBSD and passes that advantage on to you.
Enhancements:
- This release candidate is considered a large step towards a final release 1.6 with major changes such as: X.Org release 7.2, improving support for modern graphics hardware; NVIDIA graphics driver, providing hardware 3D acceleration for NVIDIA video cards; Latest FreeBSD 6-STABLE as base system with High Definition Audio (HDA) support... Upgrades from 1.0 and previous release candidates are supported. An additional language CD and 64-bit (AMD64) DVD will be released soon.

Libvirt is a C toolkit to interact with the virtualization capabilities of recent versions of Linux (and other OSes). It is free software available under the GNU Lesser General Public License.
Virtualization of the Linux Operating System means the ability to run multiple instances of Operating Systems concurently on a single hardware system where the basic resources are driven by a Linux instance.
Libvirt aim at providing long term stable C API initially for the Xen paravirtualization but should be able to integrate other virtualization mechanisms if needed.
Enhancements:
- Support for secure remote access to nodes was added.
- Many bugfixes and documentation improvements were made.

Taskjuggler is a project management tool for Linux and UNIX system-based operating systems. Whether you want to plan your colleges shifts for the next month or want to build a skyscraper - Taskjuggler is the tool for you.
Instead of clicking yourself painfully through hundreds of dialog boxes you specify your Taskjuggler project in a simple text format. You simply list all your tasks and their dependencies. The resulting schedule is then presented as GANTT chart, Table, HTML, XML or CSV report.
Taskjuggler does not only honor the task interdependencies but also takes resource constrains into account. Using Taskjugglers powerful filtering and reporting algorithms you can create task lists, resource usage tables, status reports, project calendars and project accounting statements.
Main features:
- Automatic scheduling of interdependent tasks with resource conflict solver.
- Powerful project description syntax with macro support.
- Flexible working hours and vacation handling.
- Support for shifts.
- Multiple time zone support.
- Flexible resource grouping.
- Project accounting support.
- Task may have initial costs, finishing costs.
- Resource may have running costs.
- Support for simple profit/loss analysis.
- HTML and XML report generation.
- Support for plan and actual scenario comparisons.
- Project tracking support.
- Groupware support by using a revision control system such as CVS or RCS on the project description files.
- Support for central resource allocation database.
