Today Jive Software announced its acquisition of Proximal Labs, a social network analytics company. Prior to the acquisition, Jive was a customer of Proximal Labs. Financial terms of the deal were not disclosed. Proximal Labs co-founder and CEO David Gutelius is joining Jive as Chief Social Scientist.

Jive will use Proximal's machine learning technology, powered by Apache Hadoop, to help its users apply complex analytics to their enterprise social graphs. Example use cases include locating subject matter experts both inside and outside the firewall or surfacing relevant content within the network. The company is calling the platform "Jive What Matters."

Wireless ad-hoc networks are decentralized. Each node in the network participates in routing data. Wireless Ad-hoc networks have applications in field communications (such as in military combat situations or communication in remote areas) and the Internet of Things. There could also be other applications no one has dreamed up yet. We've looked at how the Army and DARPA are developing new ad-hoc networking technology. Now, according to ITworld, two researchers have created an algorithm that may solve a major problem in distributed networking: the bottleneck problem.

Coalition forces in Afghanistan and Iraq have a major communications issue: military, security contractor and non-government organizations frequently need to communicate with each other during combat and other operations. But communications technology compatibility issues often prohibit them from doing so effectively.

DARPA contracted Ratheon in 2009 to build the "Mobile to Ad-Hoc Interoperable Network GATEway" (MAINGATE), a mobile network that both military and civilian organizations can use to communicate using any radio or wireless device. The agency announced last month that the system has now been tested for video, voice and data by both high- and low-bandwidth users.
