While smartphones are awesome little computers, one of the things that really makes them useful is their built-in sensors - many apps are made possible via a phone's accelerometer, gyroscope, GPS, microphone, camera, or some combination of the bunch. The thing is, though, all of those sensors are stuck in the smartphone. What if you want to use your phone to monitor another device? Well, that's where NODE comes in. The proposed gadget could be placed on or near a device, and would wirelessly relay data from multiple onboard sensors, via Bluetooth.

In our most recent Scientific Reports paper, we show how the visual pattern recognition ability of humans combined with the high processing speed of computers leads to a visual analytics method for discovering groups of nodes characterized by common network properties.

Let's say you have two hosts, somewhere out on the Internet: Maybe dedicated servers, maybe Amazon EC2 or Rackspace instances, maybe a mix of the above. Now assume it's your job to provide secure, encrypted connectivity between two services running on those hosts. If those services do not use an encrypted protocol by themselves - such as non-SSL capable SMTP mail servers - then the standard answer has always been: "Use stunnel or OpenVPN!". While both of those are good, cross-platform solutions which can forward unsecure traffic over an encrypted tunnel, I believe that they come not only with administrative overhead, but also introduce a significant performance hit. I believe that there are now solutions that are easier to use, more flexible and most importantly, deliver much better performance. In this article, I will compare stunnel performance  characteristics with vCider's virtual private network solution (sign up for use with up to 8 nodes is free). You will see that vCider not only offers more flexibility and is easier to use, but also provides significantly better network performance and reduced CPU load. For my test, I have created two Ubuntu instances on Rackspace. Please note that both stunnel as well as vCider can work across network and cloud provider boundaries.

FOR the past decade or so, generals commanding the world's most advanced armies have been able to rely on accurate forecasts of the outcomes of conventional battles. Given data on weather and terrain, and the combatants' numbers, weaponry, positions, training and level of morale, computer programs such as the Tactical Numerical Deterministic Model, designed by the Dupuy Institute in Washington, DC, can predict who will win, how quickly and with how many casualties.

The Tor Project is considering paying operators to host exit relays in efforts to increase the speed and security of its global anonymity network. Under early consideration is a suggestion by Tor founder Rodger Dingledine that operators receive $100 a month to cover bandwidth costs. The Broadcasting Board of Governors (BBG) has already donated an undisclosed amount of funds over 12 months to provide for at least 125 fast exit relays which would provide extra capacity for Tor users.
