Cylinders would spread the load around their circumference, the way Magdeburg hemispheres work. The issue I guess is what happens if something smacks into the cylinder, e.g. a crane. Could the cylinder take the strain even with some deformation? And even if it could, there could be pods whizzing through the tube at 400mph and you don't want things protruding inwards...
Any hyperloop system would need to have a lot of sensors watching for shock and pressure events and pods capable of hitting the brakes to avoid collisions at high speeds.
If there were a catastrophic failure of pressure between those two pods then the one in front is going to accelerate and one behind is going to decelerate. Hitting this wall at such speed might well cause the pod to slow so rapidly that it causes injuries. It's hard to say without modelling it. I doubt a smaller pressurization would do any harm.
Inviting the driver to not pay attention, fall asleep etc. is profoundly dangerous "feature" in a vehicle. I'm sure the legal battle will be interesting in apportioning the blame when one of these cars inevitably smacks into child / pedestrian, runs lights, hits other vehicles / cyclists or causes accidents through erratic or dumb behaviour.
No, it's not "all good" any more than ordering crab at a restaurant and getting fish sticks. Or buying a fake Lacoste t-shirt. The consumer is screwed and so is anyone who is competing against these knockoffs.
Sorry dipshit but no. Someone dropping a stone from a bridge can describe how they dropped the stone, the conditions it was dropped under, the weight of the stone, the distance it dropped etc and someone else can replicate the experiment. And by so doing prove or disprove the original outcome. If the outcomes concur then the observation is likely true or the experiment is flawed. Either way, something has been discovered. That's science.
Saying "well it worked for me" or somesuch is subjective whargarbl. Unsurprisingly alt medicine relies on lots of anecdotes because they are conspicuously lacking in the scientific proof department.
Nope. They're cheap because it's easy to print out a few phony certificates, buy a white coat and other trappings of medicine and pretend to be professional. Certainly much cheaper than studying for years in medical college and all the operating costs of being an actual medical practitioner.
Why play woo roulette with a chiropractor? There is no reason that a chiropractor is required at any stage in the process. Need a nice back rub? Go to a masseur. Need treatment for a physical problem? Go to a physiotherapist.
I'm aware of books existing but it's mandating their use which is the issue. It has to come down from goverments - here is our curriculum, these books conform to the curriculum, the books are paid for and free to you (electronic form), students use an e-reader, tablet or hardcopy of the books.
Because they charge insurers less than if you went to a real doctor for a real treatment. If healthcare were more affordable, or if insurers refused to cover alt health, or were compelled to offer the same plan without it at a lower premium then quackery like chiropractic, osteopaths, naturopaths etc. would shrink to the fringes where they belong.
Got a bad back? Go and see a medically qualified physiotherapist.
Hire some experts to write text books under a creative commons licence that cover the curriculum, sell hard copies at cost and electronic copies free as.epubs,.pdfs etc.
I really don't see much reason beyond special interests that schools or parents should be held to ransom by publishers for educational material.
Yup, or the car slowing to a halt. Most cars will set off really annoying sounds if you don't put your seatbelt on, and some cars won't even move without the seatbelt on.
Cruise control still requires you steer, look where you're going and keep a lookout for hazards ahead.
An autopilot practically encourages the driver to disengage their brain and that's where the issue lies. The software has to account for human nature and that means forcing the driver to remain alert to hazards and conditions on the road. That means requiring them to hold the wheel and punishing them by disabling the feature if they don't. A better system might even monitor their posture, heart rate, eye movements / pupil dilation and provide "challenges" to enforce alertness.
Yes it was at fault by allowing the vehicle to be operated in an unsafe manner. The software should have required the driver have his hands on the wheel and if the driver failed to respond to warnings it should have disabled the autopilot mode. Let's also not overlook that this autopilot was SPEEDING so clearly there is an issue there.
The reality is that no matter how safe a car might be with autopilot, it's safer again with a human alert and responsive to the conditions and other hazards. Therefore it should be a duty of these systems to ensure the human IS alert and responsive or disable these conveniences.
Yes they certainly did fail to implement common sense protocols.
The reality is these cars CANNOT drive themselves without a human being overseeing and supervising their behaviour. That means the car MUST keep the driver alert and responsive and if the driver refuses to comply the car should pull the vehicle over, reduce speed, or disable the autopilot feature altogether for some period of time.
If that's the fear then you release a single version of the operating system with a switch marked "Advanced mode" which you're asked to enable during setting if you want all the scary stuff.
Even so, Windows S is just the thin end of a very large wedge ultimately intended to separate users from the freedom to choose where they get their software from.
Every time I start Windows, the Dropbox client spends MINUTES indexing all the files in the folder during which time the computer is close to unresponsive. The more files in the folder, the worse the problem is. This is not a new problem, it's been this way for years.
I realise that it has to reconcile changes locally to remote changes but however they're doing it right now is totally fucked up. At the very least it shouldn't kill the performance of the rest of the system while it's working.
Use Opera Mini, Orfox or something like that. Failing that, don't use the store wifi and ensure not to install/use Amazon's apps, or if you do, deny them location info.
Y2K was an easy problem by comparison - fixing instances of 2 digit databases and code to use 4 digits (good til 9999). Fixing 2038 is going to be a massive clusterfuck. On the plus side I can look forward to some good paying contracting gigs to fix these issues.
Not at all because many bits of code might treat / assume that time_t is an int. It may even be that when they compiled to 64-bit and a bunch of warnings appeared they made them go away by just casting.
I'm sure this weed killer thing could probably navigate around a lawn somehow with training, but identifying weeds and cutting them in a timely fashion in a device that is solar powered seems like a difficult proposition.
I bet the amount of power required to mow, scan for weeds and recharge would not allow it to handle very large lawns. In addition, weed species are different in different climates and zones. Even grass is different in different climates and zones that affects the blades. Some grasses are even considered weeds when they sprout in a lawn with another kind of grass. And some people plant flowering bulbs like daffodils, tulips etc. in their lawns and don't want them annihilated as weeds. And edges of lawns need special attention, especially next to borders with flowers and plants. Then there are false positives from fallen leaves from other plants and trees. And of course if you leave this robot laying around somebody's going to steal it.
So a collective hmmm is in order.
On the plus side it reminds me of a crappy Tom Selleck movie called Runaway which imagined a future with robots that would pick caterpillars off of plants and mash them up. I'm sure appliance robots will eventually serve a purpose but we're not there quite yet.
Well he's certainly feeding the alt-right garden with horse manure. Sean Hannity made a complete ass of himself trying to spin a Seth Rich conspiracy story partly because of Kim claimed to have a "bombshell".
Just search any C or C++ specification and "breaking changes" and you will find breaking changes. C and C++ might be at the conservative end of the scale but even they manage to break stuff and occasionally deprecate things. In addition, while it might be nice that C/C++ doesn't change as much as Swift, it also means the language accumulates a lot of crap, some of which is horribly unsafe.
So conservatism in one way actually makes the language more dangerous and crufty in another.

If you step into a prison cell, no matter how ornate and attractive it might look, don't be surprised when the door slams shut behind you.

Osteopathy is quackery too.

That would be called an anecdote. Science and medicine works off evidence, not anecdotes.
There is benefit to everyone except publishers.
