Las Zetas kill another "blogger." A body was hung from the same overpass where two bloggers were murdered last month. According to the Houston Chronicle, a sign hung with his body said, in Spanish, "This happened to me for not understanding that I shouldn't report on the social networks."

Representatives of the Nuevo Laredo En Vivo forum denied the person was one of their moderators. One of the previous victims was a moderator there.

If you haven't yet enrolled in the Introduction to Artificial Intelligence class at Stanford University that we mentioned earlier this summer, you still have time to participate in what is being billed as the largest Google+ hangout tomorrow morning. At 8 am PT tomorrow, the two professors teaching the class, Peter Norvig and Sebastian Thrun, will hold "office hours" and answer the most popular questions from the class.

Since they have tens of thousands of followers, it "would be hard to fit everyone into their actual offices," says the intro video. It is an intriguing use of the Hangout feature. You don't have to be a Stanford student, or even enrolled in the class, or even know something about AI. All you have to do is add Norvig to your Google+ circle, ask your question on their YouTube channel now and tune in tomorrow.

Not too long ago we told you about how you can access the course materials for Stanford University's introduction to computer science course. If you're looking for something a bit more advanced, Stanford will offer its artificial intelligence class online for free this fall. It will run from Sept 26 - Dec 16. Online enrollment ends Sept 10.

The course will be taught by Sebastian Thrun and Peter Norvig. The course will include online lectures by the two, and according to the course website both professors will be available for online discussions. And according to the video embedded below, students in the online class will be graded on a curve just like regular Stanford students and receive a certificate of completion with their grade.

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.

When explaining the concept of augmented reality to someone who has never heard of it, I find myself going through a series of common real-life and pop-culture examples to help them understand. Aside from explaining that the "1st and Ten Line" in football games and the computer vision of the Terminator are indeed forms of augmented reality, I often use examples from the military - the fighter pilot heads-up-display, for example - as well. In fact, the military has played a significant role in the early development of AR, and one company is attempting to make sure it is a large factor in the future of the technology as well.

Tomorrow morning, teams from all across the United States will try to find 10 red balloons. The federal Defense Advanced Research Projects Agency (DARPA) plans to moor 10 red weather balloons at 10 fixed locations in the continental United States, and whoever sends in the GPS coordinates of all the balloons first will win $40,000. With this event - called the DARPA Network Challenge - DARPA wants to commemorate the 40th anniversary of the Arpanet - the predecessor of today's Internet. DARPA wants to test how the Internet, crowdsourcing and social networking can help to solve "broad-scope, time-critical problems." Read on to see how you can participate in this event.

The intelligence community is inputting data to the Web at an amazing rate. That mountain of data can be overwhelming to mere humans who are trying to read through pages and pages of information to pinpoint exactly what they're after. Mark Rutherford of CNET News reports that the Defense Advanced Research Projects Agency (DARPA) has hired a tech company to develop a reader that will scour the Web and render certain information and knowledge into a form that is more easily digested and usable.
