Comment: Re:get dizzy? (Score 1) 71

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.

While this is an obvious one you may have already checked, there is a developer setting to force wake on power. Have you made sure that's off? In case your dev menu is disabled, you can enable it in this manner:

After the developer options are on (if they were not already), you will see it near the bottom of the settings list. Make sure Stay awake is not selected.

I suspect that as life goes deeper there are two strategies:

  • Coping mechanisms, where things such as trimethylamine oxide are used to allow biological processes evolved at shallower environments to function. This is probably more common, simply due to the disparity in the quantity of life (and thus genes) in shallow vs deep water.
  • New biology, where completely different proteins are used, ones that simply would not work at lower pressure. We won't find these until we sequence deep sea creatures and do simulations to see what proteins are encoded, and why they work at high depths. This is hard work, and will keep biologists in work for decades.

While I absolutely agree that A) most cops are good (or at least neutral), and B) excessive measures prevents them from doing their job, I am frustrated whenever the danger of being a cop is brought up. Being a cop is less dangerous than being a fucking roofer. Do we say 'Oh no, roofers have such a dangerous job... every day they risk their lives on roofs to keep our houses safe, he just was scared for his life and that's why he punched the guy in the throat. Cut him some slack'.

Fuck no. Police should not be immune from criticism or even shielded partially due to the danger of their job. I never read about how firemen get a pass on axing someone in the face due to the dangers of their job. But that's because people who take the job of fireman are not in it for the power; they genuinely want to help. Police duties, unfortunately, attract a disproportionate number of bullies.

I agree that Rails is a fad. But touting PHP as better is... odd. PHP is a dismal language, with horrible coding practices and duplicate commands (some are bad, some are good, who knows which is which). Using a library, you have no idea what code they used... did they use the old string routine that's vulnerable to buffer overflows, or the new one? Why does PHP even KEEP the broken commands, it's insane!

Ruby is good (despite performance issues), PHP is bad. I'll take any framework built around Ruby over any framework built around PHP.
