It’s an exciting day for Citrix, our customers and the open source community as we announce some BIG news for Citrix XenServer. Today we cross another major milestone as XenServer moves to a full open source model beginning with the new XenServer 6.2. Cutting right to the chase, here are the highlights that I’ll go into more detail on:
- XenServer 6.2 is available as a free open source virtualization platform for all users
- Citrix is also introducing a new XenServer.org community portal
- Citrix provides a paid version of XenServer that includes support and maintenance
- New CPU socket licensing
- New simplified packaging and pricing
MIT researchers can see through walls using ‘Wi-Vi’
Every time a Wi-Fi signal is reflected off an object, the shape and makeup of that object affects the signal that comes back. But when Wi-Fi hits a wall, most of the signal gets reflected off the wall and only a faint bit of it reflects off the people on the other side.
To get around this, Wi-Vi transmits two Wi-Fi signals, one of which is the inverse of the other. When one signal hits a stationary object, the other cancels it out. But because of the way the signals are encoded, they don’t cancel each other out for moving objects. That makes the reflections from a moving person visible despite the wall between that person and the Wi-Vi device. Wi-Vi can translate those faint reflections into a real-time display of the person’s movements.

I have not dug into this project yet but it looks interesting.
Google making the Web faster with protocol that reduces round trips
An FAQ and an in-depth design document provide more information than most people would want to know about QUIC. Besides running multiplexed connections over UDP, QUIC was “designed to provide security protection equivalent to TLS/SSL, along with reduced connection and transport latency,” the FAQ states.

Patent troll that sues public transit systems gets hauled into court
ArrivalStar doesn’t want to litigate; it wants fast cash. The company has never taken a case to trial, and last year it admitted it had only seen one case through to the early “claim construction” phase.

NASA’s NEXT ion thruster runs five and a half years nonstop to set new record
NEXT is a solar electric propulsion system where electricity from the spacecraft’s solar panels is used to power a a 7-kW class ion thruster. In this, particles of xenon gas are electrically charged and then accelerated to speeds up to 90,000 mph (145,000 km/h). Such thrusters have already been used on spacecraft, such as NASA’s Dawn probe, and engineers are very interested in them because of their much higher performance compared to conventional chemical rocket engines.

How Much is Your Gmail Worth?
The brainchild of researchers at the University of Illinois at Chicago, Cloudsweeper’s account theft audit tool scans your inbox and presents a breakdown of how many accounts connected to that address an attacker could seize if he gained access to your Gmail. Cloudsweeper then tries to put an aggregate price tag on your inbox, a figure that’s computed by totaling the resale value of other account credentials that crooks can steal if they hijack your email.
Antenna TV Roars Back
In 2010, GFK’s survey of U.S. homes found just 14 percent of households relying on broadcast-only TV. In 2012, that number jumped to 19.3 percent and now it has risen well above the 20 million mark.

There are a lot more channels on OTA ever since they went digital and added all sorts of sub-channels.
