GNU social is a free social networking
platform and it is a continuation of the StatusNet project. It helps people in a community, company or group to exchange short status updates, do polls, announce events, or other social activities (and you can add more!). Users can choose which people to "follow" and receive only their friends' or colleagues' status messages. It provides a similar service to proprietary social network sites, but is much more awesome.
 
With a little work, status messages can be sent to
mobile phones, instant messenger programs (using
XMPP), and specially-designed desktop clients that
support the Twitter API.

Z-Push is an open-source application to synchronize ActiveSync compatible devices such as mobile phones, tablets and Outlook 2013 and above. With a history of over 9 years of successful synchronization with multiple backends Z-Push is the leading open source push synchronization.
 
Mobile data synchronization is becoming increasingly important for many people, and various standards have arisen to perform this two-way copying ‘over-the-air’. The most important platforms that can do wireless synchronisation are ActiveSync that is used to communicate with Exchange Server and Research-in-Motion’s BlackBerry Enterprise Server (BES). Both solutions require proprietary server-side software from the vendor, therefore limiting the use of PIMs (personal information managers) to either wired synchronization or irritating 3rd-party synchronizers requiring the installation of client software on the PDA.
