I'm no Googler, nor have I interviewed, but I suspect this is more about Google's hiring methods than their hiring policies or biases. They run contests, which are essentially easter egg hunts that result in a potential interview. Who has the time and inclination to play around with hoops like that? The young, college attending, and childless nerds and hackers. They don't need to have a bias in who they hire, because they create an innate bias in who chooses to apply by putting that 'application' behind a lot of hoops and rigamarole.

No such thing. You can't balance a girls school on topic A with a boys school on topic B. I don't care what private schools do with their money, but I do not want tax dollars funding this idiocy.

I am all for inclusiveness. But this is not it. This is farcical.

Try and open a publicly funded All Black School of Business, balance it with an All White School of Jazz, and tell me this makes sense. I'll be over here trying not to simultaneously laugh and cry.

The 'stiction' is evident when the rocket is initially coming down and swinging to the left of the video frame, before you see it (over-)correct and swing back to (and past) vertical. I watched that section wondering why the rocket went excessively to the left in the first place, and a stuck valve makes a lot of sense.

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.
