Together the package provides support for thousands of users to concurrently send and receive email and schedule meetings. MCS uniquely allows you to store all messages and scheduling events in nearly any database and runs on nearly all popular software and hardware platforms.
Additionally, while the scheduling and calendaring services are able to be installed separately, the integrated featureset provides both a unique and powerful experience to both users and server-side Mail Based Applications and Collaboration Based Application Services.
The MCS platform provides security integration using LDAP sources including Microsoft Active Directory as well as flat-file and Database sources. Additionally, extensible security allows custom authentication/authorization sources.
Enhancements:
- IMAP is now stable with Mozilla Thunderbird and POP/SMTP are production ready.
- New Filestore code was implemented and many improvements were made in mailbox and storage code.

Ice, the Internet Communications Engine, is middleware for the practical programmer. A high-performance Internet communications platform, Ice includes a wealth of layered services and plug-ins. Ice means simplicity, speed, and power.
Ice is available under the terms of the GNU General Public License (GPL). Commercial licenses are available for customers who wish to use Ice with proprietary products. Please contact sales@zeroc.com for more information.
Ice is currently available for C++, Java, C#, Visual Basic, Python, and PHP, and is supported on various operating systems. Additional operating systems and languages will be supported in future releases.
Ice consists of the following packages:
Slice The Specification Language for Ice. Slice establishes a contract between clients and servers, and is also used to describe persistent data.
The Slice Compilers Tools to compile from Slice into target languages, such as C++ and Java, or to automatically generate documentation from Slice files.
Ice The Ice core library. Among many other features, the Ice core library manages all the communication tasks using a highly efficient protocol (including protocol compression and support for both TCP and UDP), provides a flexible thread pool for multi-threaded servers, and additional functionality that supports extreme scalability with potentially millions of Ice objects.
IceUtil A collection of utility functions, such as Unicode handling and thread programming. (C++ only.)
IceBox An application server specifically for Ice applications. IceBox can easily run and administer Ice services that are dynamically loaded as a DLL, shared library, or Java class.
IcePack A sophisticated server activation and deployment tool. With IcePack, the complex task of deploying applications in a heterogeneous computer network is dramatically simplified. Simply write a deployment descriptor in industry-standard XML, and IcePack handles the rest.
Freeze Freeze provides automatic persistence for Ice servants. With just a few lines of code, an application can incorporate a highly-scalable evictor that efficiently manages persistent objects.
FreezeScript It is common for persistent data types to change, especially in large software projects. In order to minimize the impact of these changes, FreezeScript provides inspection and migration tools for Freeze databases. The tools support an XML-based scripting capability that is both powerful and easy to use.
IceSSL A dynamic SSL transport plug-in for the Ice core. It provides authentication, encryption, and message integrity, using the industry-standard SSL protocol.
Glacier One of the most difficult challenges for object middleware systems is security and firewalls. Glacier, the firewall solution for Ice, greatly simplifies the deployment of secure applications. Glacier authenticates and filters client requests and allows callbacks to the client in a secure fashion. In combination with IceSSL, Glacier provides a powerful security solution that is both non-intrusive and easy to configure.
IceStorm A messaging service with support for federation. In contrast to most other messaging or event services, IceStorm supports typed events, meaning that broadcasting a message over a federation is as easy as invoking a method on an interface.
IcePatch A patching service for software distributions. Keeping software up-to-date is often a tedious task. IcePatch automates updating of individual files as well as complete directory hierarchies. Only files that have changed are downloaded to the client machine, using efficient compression algorithms.
Enhancements:
- Various additions, including redundant IceGrid registries.

URBI: Universal Robotic Body Interface. URBI is a scripted command language used to control robots (AIBO, pioneer,...). It is a robot-independant API.
URBI Project is based on a client/server architecture and it is designed to be used over a TCP/IP or IPC connection.
Main features:
- URBI is a low level command language. Motors and sensors are directly read and set. Although complex high level commands and functions can be written with URBI, the raw kernel of the system is low level by essence.
- URBI includes powerful time oriented control mechanisms to chain commands, serialize them or build complex motor trajectories.
- URBI is designed to be independant from both the robot and the client system. It relies on TCP/IP or Inter-Process Communication if the client and the server are both running onboard.
- URBI is designed with a constant care for simplicity. There is no "philosophy" or "complex architecture" to be familiar with. It is understandable in a few minutes and can be used immediately.

Process Viewer is a small utility similar to top which displays all the processes on a linux system. Its written using the FOX Toolkit.

Process Viewer is licensed under the GNU General Public License

Quanta Plus is a highly stable and feature rich web development environment. Quantas vision has always been to start with the best architectural foundations, design for efficient and natural use and enable maximal user extensibility.

We recognize that we dont have the resources to do everything we would like to so our target is to make it easy for you to help make this the best community based desktop application anywhere. Pretty much everything in Quanta is designed so you can extend it.

Even the way it handles XML DTDs is based on XML files you can edit. You can even import DTDs, write scripts to manage editor contents, visually create dialogs for your scripts and assign script actions to nearly any file operation in a project. You can even look at and communicate with a wide range of what happens inside Quanta using DCOP.

Quanta is based on KDE so this means it is network transparent from any dialog or project. It can use not only FTP but other KDE KIO slaves from file dialogs or in project settings. For instance if you want secure access try the fish KIO slave that uses SSH.

Just enter fish://[user]@domain in any dialog or select fish in your project settings. Here on this site you will find information on using Kommander to visually build dialogs you can extend Quanta with. These applications talk to each other using an IPC (Inter Process Communication) called DCOP (DEsktop Communication Protocol).

Of course I realize this can sound like alphabet soup techno-babble to some web developers, but heres what it means. When you are using Quanta and realize you would like to do something and you want to ask "Can I do this?" you can expect the answer will not only be yes, but it will probably be even cooler than you hoped for.

Not included on this site are other tools you can use with Quanta for revision control and reviewing and merging changes in files. Those applications are Cervisia and Kompare, and if they are not installed and you install them Quanta will use them.

We would like to think that there are rich rewards to be found here for those willing to explore new ways of doing things, or perhaps in some cases old ways that are just new to you.
