Air gap... like Bluetooth?

I know what the term means, but heat is just another type of EM radiation (infra-red) that doesn't have dedicated communication hardware. The accomplishment is neat, but not useful.

As a counter-example, the paper on reading monitors from their diffuse reflected luminance is actually useful. You get a high-bandwith, air-gapped eavesdropping method. This communication by heat is more likely to be detected (as a problem, not necessarily as communication) than a steganographic (thank you) communication channel using more common EM radiation.

I'm not saying it's not 'neat'. It's just not neat and useful.

Not hack. They have not infected computers using thermal energy. They just demonstrated slow (very slow) communication between two computers using heat and heat sensors. It uses a tremendous amount of battery power of little to no purpose, since both computers need to already have the software on them... stenography would be a more appropriate communication method (hiding communication in seemingly-innocuous em traffic).

Comment: Paid vs Hobby (Score 3, Insightful) 133

Someone paid to do a job they dislike, with people they don't know, are likely to do only as good a job as they need to get paid. When they are very far away, that could be very little at all.

Someone volunteering to do a job they enjoy with remote people who share the same hobby and ideals? Unsurprisingly, they tend to do a better job, despite the lower accountability you have when working remotely.

This isn't rocket science.

Not quite. It will be muffled, but not missing. Simulators can accurately change the angle of acceleration force to match your expectation, even if they cannot change the magnitude. The result, when you have actuators that are fast enough, is amazingly immersive. Some users will have simulation sickness, but others will not; similar to other types of motion sickness it varies wildly.

What's the false positive and false negative rates of this cheap test, vs the normal one? While it's probably better to have a mediocre test rather than none at all, there are times when that's not true... high false positive rates for rare conditions can waste resources on healthy individuals. High false negative rates for common conditions can give patients a false sense of safety.

The specificity of the test matters a lot before you can judge its utility.

This aligns with Google's interests (get everyone online to see ads), so it's an obvious investment. Elon has shown to be capable of getting shit done, so it's a safer investment than some previous attempts at low-orbit Internet (like Iridium) even ignoring the technical advancements we've had in the past decade. Plus, with the lifter and cargo owned by the same company (one that has proven capable of lower-cost-to-orbit) the economics work out better than ever.

Artist makes up stuff. We can't reliably entangle molecules, let alone making two macroscopic telescopes have any quantum relationship. In adition there is nothing special about the cosmic background radiation; the CCD could have had any quantum effects he is aiming for imbued on earth.

Nothing but a publicity stunt with no scientific backing.

I'm not an Android or iPhone fanboy, but I'd like to point out that (unlike iOS), there are new devices being released with Android 4.3 on them. 4.3 was released about a year ago. It's not old.

Google should be making a patch and publishing it to make it as easy as possible for phone manufacturers to patch their crap. It would be appropriate for Google to continue to provide security patches for any version of Android still in new devices.
