PTlink IRC Services provides channel/nick registration services for IRC networks.
Specially developed for the PTlink IRC Server, it uses modules and includes features like channel roles and nick groups for privilege management.
The data backend is a MySQL database.
Enhancements:
- This version fixes a synchronization problem with user kicks, replaces some fatal errors with warnings, and updates the utility scripts to reflect the latest configuration changes.

Open Project Services (OPS) is a project collaboration platform, integrating server components such as e-mail, calendaring, timesheets, documents, knowledge, etc. with standards complient clients. Open Project Services consists of a project server and a set of client extensions.
We are building a project collaboration platform. It consists of a project server that integrates with services needed within a project, e.g. e-mail, calendaring, timesheets, documents, knowledge, etc.
The project server is a Webservices hub based on Java (J2EE). The persistence layer for project information is LDAP. We use OpenLDAP now, but others should also be possible. The e-mail backend makes use of a standard IMAP server. Our reference implementation uses Courier.
We are building extensions/plugins for clients, making them OPS-enabled. We support e.g. Mozilla Thunderbird (XUL) and Squirrelmail (PHP) for e-mail clients. For the calendaring and timesheet components we have a Mozilla Sunbird extension (XUL).
In short: we are building a project collaboration environment on an OSS stack, enriching services with project information, using COTS clients/servers and open standards.
Enhancements:
- This release includes some changes to the underlying LDAP schema to make it possible to disable tasks when they are completed.
- To make use of this new feature, the Web services and the sunbird timesheet client have to be updated.

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.

ICWS provides a Web services (SOAP) interface for information currency systems. Information Currency Web Services implementation uses Java, the Axis SOAP engine, and the PostgreSQL database server.
Information Currency CVS is a work-alike adaptation of CVS which returns information currency for committed source code.
Allocation of economic resources by financial mechanisms is an essential part of modern economies, and financial innovations have been a powerful force for human progress. Information technology provides the opportunity to create new economic instruments derived from any arbitrary element of information.
Information currency units are economically scarce objects that are issued and maintained by a service that establishes a correspondence between underlying units of information and information currency. Information currency will enable the application of economic mechanisms for information management and valuation.
Information currency units can be traded for other economic instruments, and the trade value of information currency units provides an economic valuation of the underlying information.
Enhancements:
- This release adds the first code for trading information currency, as well as a new Internet draft with an example trade.
