Mark Cuban's Blog: AEREO – Everything Old is New Again
AEREO deserves a lot of credit for their effort. It was a long and expensive shot to do what they went for. But they went for it. And they attempted to pivot after their SCOTUS loss. I was watching with interesting, because it is something we had examined 15 years ago at Broadcast.com
The technology has obviously gotten better on all sides of the equation, but sometimes a good idea is a good idea. Even if it is hard to make work. This is from January of 2000. What is fascinating is the alliances and attempts that were being made or considered. We also did the same kind of work to determine if we could set up antennas and a server for individual users and see if that was legal
Below it you will find a doc from 1999 where we tried to do the same thing in a different way a few months earlier.

Naked selfies extracted from 'factory reset' phones
Naked selfies extracted from 'factory reset' phones
Thousands of pictures including "naked selfies" have been extracted from factory-wiped phones by a Czech Republic-based security firm.
The firm, called Avast, used publicly available forensic security tools to extract the images from second-hand phones bought on eBay.
Other data extracted included emails, text messages and Google searches.
Experts have warned that the only way to completely delete data is to "destroy your phone"
New display technology is thinner, lighter than ever
Sounds like the perfect display device for digital holography.

New screen technology paves way for digital contact lenses
The display material is ultra thin and light, and once an image is drawn on it no power is needed to keep it there - click on the arrows above to see an example of an image made of nano-pixels (Oxford University)
Imagine having an ultra high-resolution display built directly into a pair of contact lenses.
This could be the future of digital displays thanks to scientists at Oxford University, who have adapted a material currently used to store data on DVDs and transformed it into a radical new display technology.
Writing in Nature today, they say the material could usher in a new generation of displays that are thinner, lighter, with higher resolution and lower power consumption than any existing technology.
They could even be mounted on flexible or transparent surfaces, raising the possibility of applications beyond just e-readers and smartphones to things such as car windshields and contact lenses.
The development relies on the same process that turns water into ice cubes in your freezer. Many substances undergo changes in structure when they change temperature, such as going from solid to liquid, or crystalline to non-crystalline.
These phase-change materials are currently used for a wide range of applications, from computer memory and rewritable DVDs to advanced forms of home insulation.
The team, led by Professor Harish Bhaskaran, was exploring other uses of phase-change materials like germanium antimony tellurium (GST), when they realised they might be able to use them to produce a colour display.
They took a single layer of GST just nanometres thick and sandwiched it between two ultra-thin layers of a transparent conductor, and stuck that on top of a mirrored surface.
The researchers predicted that by varying the thickness of one of the transparent layers, they could change the colour of light that was reflected back, and by changing the phase of the GST they could switch it from one colour to another.
They then built a prototype to see if the material could change from grey to blue when it was heated.
Thinner, lighter, higher resolution
"We couldn't believe it. It worked on the first attempt. So we tried it with a few other colours and it worked well," says Bhaskaran.
"I've been an experimentalist for a long time, and I've never seen things work this well at the first attempt."
The researchers then used the head of an atomic force microscope to draw a monochromatic image on the surface.
They also constructed a single pixel using a transparent electrode, which is a crucial step in producing a workable display technology.
Bhaskaran says the technology has many potential advantages over existing displays.
The layers of film are only nanometres thick, the display can be ultra thin and light, and once an image is drawn on screen it requires no power to keep it there.
And, because the pixels are only nanometres across, the resolution of the screen is potentially far higher than what is achievable with today's technologies, such as LCD and organic LED.
While it's still early days for the phase-change technology, Bhaskaran and his team are hopeful that it might migrate from the lab into electronics stores within several years.
"We have a patent filed and we are developing a monochrome prototype," he says.
"We want to show that it can render video on a really small display to showcase the super high resolution that is possible. Hopefully that'll be done by the end of 2015. If that works, then we'll take it from there."
"Highly novel"
The technology is a highly novel use of an existing phase-change material, says Dr John Daniels, senior lecturer in materials science at the University of New South Wales.
"It's an old material technology being used for a new popular application," says Daniels, who wasn't involved in the research.
However, there are still significant hurdles to overcome in turning it into a workable display technology.
"My big concern is the range of colours and contrast the technology can produce. That's the big question mark: whether they can make these materials competitive with the real market leader, which is organic LED, in terms of quality."
But he concedes that this is a fast-moving industry, and new technologies can potentially gain dominance rapidly.
"It always is a long way from the first demonstration to the first application. But this is a field where things can go from the lab to application in a very short period of time because the dollars are so big if they have something that's better than what's on the market at the moment."

Researchers find brain activity response different for virtual reality versus the real world
(Phys.org) —A team of researchers from the University of California has found that one part of the brain in rats responds differently to virtual reality than to the real world. In their paper published in the journal Science, the group describes the results of brain experiments they ran with rats. They found that "place" cells in the rats' hippocampus didn't light up as much when immersed in a virtual reality experiment as they did when the rats were engaging with the real world.
Researchers in many parts of the world are studying how virtual reality works in the brain. Some do so to better learn how the brain works, others are more interested in creating games or virtual reality environments to allow people to experience things they couldn't otherwise. In either case, despite the increase in processing power and graphics capabilities, virtual reality systems just don't live up to the real world. People can always tell the difference. To find out why, the researchers in this new effort turned to rats—most specifically, their hippocampus's—the part of the brain that has been identified as building and controlling cognitive maps.
The hippocampus has what are known as neural "place" cells. Researchers believe they are building blocks that are used to assemble cognitive maps—they become most active when a rat is introduced to a new environment. Once a mental map has been created, rats use them to recognize where they are. To find out if the place cells respond differently to virtual reality, the researchers created a virtual reality environment that was nearly identical to one that existed in the real world—including a treadmill type ball to allow for simulating movement. They then attached probes to the brains of several test rats and measured place cell activity as the rats were exposed to both the virtual reality environment and the real one.
The researchers found that the level of place cell activity that occurred was dramatically different between the two environments. For the real world runs, approximately 45 percent of the rats' place cells fired, compared to just 22 percent for the virtual reality runs.
These results weren't a surprise to the team as previous research has suggested that place cell activity is incited by at least three types of cues: visual, self-motion and proximal. Virtual reality in its current state isn't capable of generating the sensation of a breeze kicking up, the smell of bacon frying or the way the ground responds beneath the feet—all of these are part of proximal awareness. In order for virtual reality to become truly immersive, the research suggests, proximal cues must be added to the virtual reality experience.

ABSTRACT
The hippocampal cognitive map is thought to be driven by distal visual cues and self-motion cues. However, other sensory cues also influence place cells. Hence, we measured rat hippocampal activity in virtual reality (VR), where only distal visual and nonvestibular self-motion cues provided spatial information, and in the real world (RW). In VR, place cells showed robust spatial selectivity; however, only 20% were track active, compared with 45% in the RW. This indicates that distal visual and nonvestibular self-motion cues are sufficient to provide selectivity, but vestibular and other sensory cues present in RW are necessary to fully activate the place-cell population. In addition, bidirectional cells preferentially encoded distance along the track in VR, while encoding absolute position in RW. Taken together, these results suggest the differential contributions of these sensory cues in shaping the hippocampal population code. Theta frequency was reduced, and its speed dependence was abolished in VR, but phase precession was unaffected, constraining mechanisms governing both hippocampal theta oscillations and temporal coding. These results reveal cooperative and competitive interactions between sensory cues for control over hippocampal spatiotemporal selectivity and theta rhythm.
