A rolling road is another term for a chassis dynamometer.
I thought a dyno is a mechanism that a standalone engine can be rigged up to on the bench to test it under (typically computer-) controlled conditions, measure its output, simulate different driving conditions, etc.
dynos can measure at the engine (in which case they measure brake horse power) or at the wheels. Most individuals are more familiar with the ones that measure at the wheels, as that's how they would measure the effect of after-market modifications.
Not sure if how company who netted $18 billion in their last quarter needs to generate buzz. Either way, bringing a car to market is a wise move for Apple never struck me as a great idea. I've always suspected there's just too much good will and little-guy championing for Tesla to make Apple's offering a thing we want to own. Tesla vehicles are also incredibly well designed, aesthetically pleasing, and have a tonne o…
I'm curious about the words "working-class neighborhood". Is this tongue-in-cheek? I've been trying to find housing in that area and it's on par with East Bay, if not worse.
I'm expecting overhead drone imagery on YouTube in 3...2...1...
Oh no, a joke. Downvotes for you now!
I see you making sarcastic comments about all the silly noise that's being added to the thread. This is exactly the kind of noise we want to avoid on HN: https://news.ycombinator.com/item?id=10933288.
Well went thru the links and not one sound clip I heard of this noise - which I find equally just as odd, lots reports of the noise and clips of people getting there slot of TV fame, but not one link to the actual noise - least what I gleaned thru. So who knows, just equally as odd no recordings I could find of this noise, though there must be some out there somewhere I'd imagine if it is that much of an issue.
Given the ubiquity of sophisticated cell phones and other recording equipment, it's best to regard the lack of a recording as strong evidence that it does not exist. Just as if multiple people claimed the Loch Ness Monster had surfaced in San Francisco Bay but somehow there were no photographs of it.
Cell phones have shitty mics (because physics).
You would need a condenser microphone for low level noises. Around $100.
TV camera crews have them, not even one stood around waiting for the sounds?

Even better, hang it from a 20' cable below a drone and fly it over. Stream the audio back in case they somehow manage to disable the drone. I'm sure lots of people in the Bay Area have the equipment right now to do this, just a matter of if anyone cares.
Are you? http://www.pge.com/en/mybusiness/rates/tvp/toupricing.page?W... Instead of a single flat rate for energy use, time-of-use rate plans are higher when electric demand is higher. This means when you use energy is just as important as how much you use. Winter has two rate periods: off-peak and partial-peak. Summer has three: off-peak, partial-peak and peak. During peak periods, defined as weekdays from noon to 6…
Yes. Sure, we all know that electricity is cheaper at night, but would it make overall sense for the engineers to do their work at night for this reason? First, they don't have to use the energy when they draw it from the grid. Charge an EV at night and test it all day. Second, it only costs a couple bucks to charge an EV car even at peak rates. Surely the engineer's time and schedule is more important.
Depends on what type of work they are doing there. If it's light manufacturing, given the discussion of wobbly sheet metal and the like, you really wouldn't have many engineers there on shift, you'd have machinists who like working second shift/graveyard. Plus, given the location and security presence, it makes it a lot easier to chase curious people away while people are working.

Yes, but article clearly states the neighbours can't stop talking about it. They're so busy talking about it that they haven't made time to record it. Be patient. As soon as they all stop talking about it we can hear the noise. What a BS linkbaity vaporous article. For all anyone knows Apple could be repairing an AC unit. Oh, and while I'm in a ranty mood. Aren't all labs "mysterious" from the outside?
That would hardly explain the hypervigilant security people harassing bystanders on public property and thoroughfares.
I stay right besides sunnyvale apple office but have never heard of anything! :/
This isn't at the Sunnyvale office; it's an unbranded black site. Perhaps they interrogate their Google captives there as well; it's just about halfway between Apple and Google HQs.
