Submission + - China's Quantum Radar Could Detect Stealth Planes and Missiles (popsci.com)

hackingbear writes: China Electronics Technology Group Corporation (CETC), China's foremost military electronics company, announced that its groundbreaking quantum radar has achieved capability of tracking high altitude objects, likely by increasing the coherence time entangled photons. CETC envisions that its quantum radar will be used in the stratosphere to track objects in "the upper atmosphere and beyond" (including space). Quantum can identify the position, radar cross section, speed, direction and even 'observe' on the composition of the target such as differentiating between an actual nuclear warhead against inflatable decoys.. Importantly, attempts to spoof the quantum radar would be easily noticed since any attempt to alter or duplicate the entangled photons would be detected by the radar. The news is an important illustration of a larger trend of Chinese advancement in the new, crucial area of quantum research. Other notable projects in China's quantum technology include the Micius satellite, and advances by Alibaba and the Chinese University of Science and Technology in a world record of entangling 18 photons (a quantum supercomputer would require about 50 entangled photons), such that China arguably leads the world in quantum technologies.

Comment Youtube casting fatally broken. No longer usable. (Score 4, Informative) 142

This update hosed casting Youtube from my Android phone. It constantly loses the queue. It constantly plays audio only with no video. If another user connects to YouTube the queue is lost. Users constantly booted from being connected. The currently playing box in the lower right disappears preventing any way of controlling the remote device you're casting to. There could not have been any testing prior to this release.

Researchers Detect Android Apps That Connect to User Tracking and Ad Sites 74

An anonymous reader writes: A group of European researchers has developed software that tracks the URLs to which cellphone apps connect. After downloading 2,000+ free apps from Google Play, they indexed all the sites those apps connected to, and compared them to a list of known advertising and user tracking sites. "In total, the apps connect to a mind-boggling 250,000 different URLs across almost 2,000 top level domains. And while most attempt to connect to just a handful of ad and tracking sites, some are much more prolific. Vigneri and co give as an example "Music Volume Eq," an app designed to control volume, a task that does not require a connection to any external urls. And yet the app makes many connections. 'We find the app Music Volume EQ connects to almost 2,000 distinct URLs,' they say. [Another major offender] is an app called Eurosport Player which connects to 810 different user tracking sites." The researchers plan to publish their software for users to try out on Google Play soon.

I think unfortunately most Americans are asied on bits and lumps of dried meat and canned foods. I'm American and our culture here is very much to toss in our mouths anything tasty. There is absolutely zero awareness that our bodies are both physically and chemically comprised of the nutrients we ingest. I try to inform others about this and am often looked upon as a health nut for just encouraging ingestion of real food. Nothing extreme, just actual food. We are raised on foods that solely come from packages, whether plastic or metal so the idea of real food perplexes many.

I agree with everything you said... education is key. Growing up in a small football town with terrible education my parents were early internet adopters and gave me full access to it. It utterly opened my eyes to a bigger more amazing world beyond small-town football and religion. I hope to see amazing changes with information access and specifically web-based schooling to provide quality education independent of geography, local funding, etc.

It would be spectacular if movies were made based upon potential Nasa missions and the awesome adventures that would entail. Perhaps that would get through to the masses. Unfortunately these thins are so mind-boggling to our uneducated masses that they don't see the amazing technical feat and engineering this requires, nor the art and wonder of it all. It's beyond their culture of lulz, shopping, and life stress. We love our movies though and they can still help us remember how to dream. I'd love to see a resurgence of sci-fi with an aim at inspiring us to push forward.

AT&T Blocks Part of 4chan 342

holdenkarau writes "Several news sources (Mashable, The Inquistr, etc.) are reporting that AT&T is blocking img.4chan.org in the southern United States. That server is used for the infamous /b/ board (the home of anonymous). TechCrunch calls the decision to block 4chan 'stupid,' noting that they may have 'opened perhaps the most vindictive, messy can of worms.' The Inquisitr suggests that 'The global internet censorship debate landed in the home of the free.' moot (who runs 4chan) asks users to call AT&T, while some others suggest more drastic action (like cutting AT&T fiber)." Update: 07/27 09:23 GMT by T : Readers' comments below suggest that a) the purpose of the block was to curtail the effects of a serious DDoS attack and b) that the block has now been lifted, at least for some regions.
