Free social services software for linux

The QDS library allows Qt applications to access features provided in common desktop APIs in a portable way, without requiring dependencies on any desktop platform library.
This is especially useful for applications targeting the Unix desktops, because Qt/X11 is very generic and only provides features it can implement on all sub platforms. All library code is licenced under 2-clause BSD licence.
Service implementations are loaded from plugins which link to the respective desktop libraries. The plugin to use can be specified on the applications commandline, in the QDS configuration file or QDS can try to autodetect the currently running platform.
Enhancements:
- Autodetection to use GNOME plugin in case GNOME_DESKTOP_SESSION_ID is set
- Replaced the primitive example application with a simple but network aware text editor application
- Support for wildcards in mailcap entries

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.

Logging Services project is intended to provide cross-language logging services for purposes of application debugging and auditing.
We should also mention that thanks to the relentless efforts of many developers, we have a basic level of interoperability between the following projects:
- Log4Cxx (c++)
- Log4j
- Log4Net
- Log4Perl
- Log4PHP
- Log4PLSQL
- JDK1.4s util.logging framework
There is still much work ahead bringing in the various projects to work together within the Logging Services Project. The process is likely to take a little while. In the mean time, we will continue to do what we like best, that is developing open source software.
This is a project of the Apache Software Foundation (ASF). Like all Apache projects, we encourage a collaborative, consensus-based development process. We offer an open and pragmatic software license, and we strive to create software of the highest quality. The ASF is organized into several projects, which like Logging Services project may contain multiple sub-projects.

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.

Thunderbird Service Menu is a service menu that will allow you to right click on a file and attach it to a new E-mail from Thunderbird.

Just extract the "AttachToThunderbirdMail" config file to "/usr/share/apps/konqueror/servicemenus" and it should work.

IRC Services are Services for IRC Networks (or just Services for short) provides for definitive nickname and channel ownership, automatic channel mode setting, memo (short message) storage and retrieval, and greater IRC operator control over the network.
Main features:
- Nickname management. Services allows users to "register" nicknames, and will prevent users other than the registrant from using them. Services also maintains information about each registered nickname, including the last time the nicks owner was online as well as a URL and E-mail address that can be set by the user.
- Channel management. Like nicknames, Services allows users to register channels as well. A channels owner can give privileges to other users of the channel, such as auto-opping or the ability to set various channel options, or conversely deny other users the ability to obtain channel operator privileges or even enter the channel altogether. Services will remember the topic on the channel even after the last user leaves, and can automatically set modes on the channel whenever a user joins it.
- Messages to offline users. Probably every IRC user has gone through the experience of waiting and waiting for someone to come online in order to pass a message along or ask a question. Services alleviates this with a "memo" system, allowing users to leave messages for other users even if the recipient is not online at the time; the recipient will be notified of the memo the next time they log on.
- Centralized network control. Services includes features which allow IRC operators greater control over the IRC network through a single point, and also defines multiple privilege levels for IRC operators with respect to Services itself. For example, IRC operators with sufficient privileges can use Services to set modes on any channel; it is also possible to ban users or groups of users from connecting to the network entirely, and such bans ("autokills" in Services terminology) will remain active even if a server, or Services itself, splits from the network.
Furthermore, each of these sets of features can be configured or disabled to match individual networks policies.
Whats New in 5.1pre4 Development Release:
- This release corrects various minor issues in the previous beta release and updates the ratbox protocol module to better support current versions of the ircd-ratbox server (note that versions earlier than 2.1 are no longer supported).
Whats New in 5.0.61 Stable Release:
- This release fixes a bug which allows users to crash Services on x86-64 (and potentially other non-x86) platforms.
