Uber drivers are subsidized by everybody else. Taxi drivers have to pay high insurance rates because the act of driving a long distance every day for a ton of strangers is a job that inherently leads to a much higher statistical rate of payouts. If they're driving as a taxi on regular car insurance, it's you that's paying the bill for their swindle of the insurance system.
Yeah, wouldn't that be great if I had linked it in my first post, and then if you had actually read my post well enough to see it?
How do you come to that assumption?
By linking to a peer-reviewed paper on the subject?
A nuclear warhead has lots of trouble to even "hit" an asteroid.
Essentially every space mission we have launched for the past several decades has had to navigate with a far more precision than that needed to get close to an asteroid and activate a single trigger event when close by.
Human female breasts are disproportionally large compared to other animals. That's because as bipeds, breasts have replaced the role of a large round ass that females use to attract males in the animal kingdom.
We send spacecraft on comparable missions all the time. And it doesn't really take a spectacularly large payload to destroy (yes, destroy) an asteroid a few hundred meters in diameter. 1/2-kilometer-wide Itokawa could be blown into tiny bits which would not recoalesce, via a 0,5-1,0 megatonne nuclear warhead, a typical size in modern nuclear arsenals (in addition, the little pieces would be pushed out of their current orbit).
I know it's a common misconception that "nuking" an asteroid would simply create a few large fragments that would hit Earth with even more devastation, but that's not backed by simulation data. And anyway, even if it didn't blow the asteroid to tiny bits (which simulations say it would) and even if it didn't push the remaining pieces off trajectory (which they say it does), anything that spreads an Earth impact out over a larger period of time is a good thing - it means the higher percentage of the energy that's absorbed high in the atmosphere rather than reaching the surface (less ejecta, lower ocean waves, a broader (weaker) distribution of the heat pulse, etc), the weaker the shockwaves, the weaker the total heat at any given point in time, and the more time for Earth to radiate away any imparted energy or precipitate out any ejecta cloud. If the choice is between 15 Chelyabink-sized impactor (most of which will strike places where they won't even be witnessed) or one Meteor Crater-sized impactor (same total mass), pick the Chelyabinsk ones. 50 10-megatonne meteor crater impactors or one 500-megatonne Upheaval Dome impactor? Pick the former. The asteroid impacts calculator shows the former generating a negligible fireball and 270mph wind burst at 2km distance, while the latter creates the same winds 25km away (156 times the area) and a fireball that even 25km away is 50 times brighter than the sun, hot enough to instantly set most materials on fire.
But that's all irrelevant because, quite simply, simulations show that nuclear weapons do work against asteroids.
What we need is enough detection lead time to be able to launch a nuclear strike a few months before the impact date (to give time for the debris to disperse). There is no need to "land" or "drill" for the warhead. There is no pressure wave; instead, an immense burst of X-rays is absorbed through the outer skin of the asteroid on the side of the explosion, causing it to vaporize (unevenly) from within, especially near the ground zero point, and creating powerful shockwaves throughout its body. In addition to ripping it apart, the vaporized material and higher energy ejecta flies off, predominantly on the side where the explosion was detonated, acting a broad planar thruster.
On the other hand, if they're doubling capacity, then you only need half the number of cycles (it actually even works *better* than that, as li-ion cells prefer shallow charges and discharges rather than deep ones - but yes, fractional charge cycles do add up as fractional charge cycles, not whole cycles). If you have a 200km-range EV and you drive 20 kilometers a day, you're using 10% of a cycle per day. If you have a 400km-range EV and you drive 20 kilometers a day, you're using 5% of a cycle per day.
Top commercial li-ion capacities are about 30% more than they were 5 years ago. And today's batteries include some of the "advances" you were reading about 5 years ago.
I'm sorry if technology doesn't move forward at the pace you want. But it does move forward when you're not looking. Remember the size of cell phone batteries back in the day?
Specifically designed low-altitude parachutes are effective at a few hundred feet. No, it won't save you at extreme low altitudes and velocities, but it's certainly better than nothing.
To quote a friend describing the first of the micro-nuts (rock climbing protection equipment), "they might not stop you, but they'll sure as hell slow you down!".
With strengths (breaking loads) from 2 to 6 kN, you don't need to fall very far for a nicro-nut to pull. But in doing so, it absorbs a considerable amount of energy. And the next one does too. It's not nice, but it really does slow you down.

Well, at least until the accident...
In reality though, most rides these days seem to go out of their way to make sure that there's nothing actually dangerous within reach of anyone in the cars. Even if you slip out of your seat and stand up, etc. Sure, you'd have to be a grade-A dumbass to do such a thing, but even grade-A dumbasses getting themselves dismembered on your ride tends to make or bad publicity.
Probably also a generation or two of "we're here to help" medical programs not being hideously abused, as was done in various population-control endeavours and other programs. Involuntary sterilization under the guise of vaccinations? Really? That's the sort of horror story that can take generations to fade, and it seems like every time we start building back some trust among the population, someone decides to abuse it yet again.
Software failures will scale up similarly. If you propose for example that, on any single PC, a Linux crash is 10x more likely than a hardware failure, then they're be dealing with dozens of crashes per day - and that would have to be some pretty stable software. What's your crash to hardware-failure ratio?
Taubira doesn’t actually have the power to offer asylum herself, however. She said in the interview that such a decision would be up to the French president, prime minister and foreign minister. And Taubira just last week threatened to quit her job unless French President François Hollande implemented her juvenile justice reforms.
So, basically, "not going to happen".
The way this works with British Telecom is that you have multiple SIDs on your router. There's one you connect to that you have control over, and there are also additional SIDs like "BTWifi-with-FON" and "BTWifi-X" with separate IP address and logging that you have no control over.
I think that BT internet customers have a free access to these all over the country and if they opt-out of this they can then get it disabled on their own home router. This way BT claims they literally have millions of WIFI access points all over the country, yet the experience is terrible if actually the network is on residential ADSL (upstream capped to 448kb/s for instance).
Incidentally I've wondered whether you could just replace their ADSL or VDSL (FTTC) router with something of your own without these additional access points and still been able to access their national network of access points for free.
Not quite the way it works bud. You DO have control over the public hotspot.. in settings you can turn it on or off.
Also it's a trivial matter to change router. I have this puppy which is future proof enough for me, can handle any isp/connection type(adsl,vdsl, cable) and when you run the Asuswrt-Merlin firmware . it gives you a lot more settings to tweat and explore and is a pretty fucking rock solid router and it looks sweet
BTW your BT connection username and password is user = BT passie = user i shit you not.
I left BT and moved to talktalk... I know. they are SHITE but at 26 quids all in for 80mb down and 20mb up including phone charges(just tell them you will go to sky.. they'll give you an offer) and i am 60 meters by wire from the cabinet. I am in the process of getting all the other flats on my stair to sign up to http://hyperoptic.com/
also.. i can STILL use my BT-wifi/FON login anywhere in the world and it's been 6 months since i left BT and i've used it here in Scotland, in England,in Portugal, Denver,Houston, Amsterdam New Jersey and the Republic of Ireland. it's the gift that keeps on giving as the turds are too lazy to check status more than the initial one
Nothing wrong with a piece of fiction with laughably bad science on almost every page. If someone gets a kick out of the book, then it's met its purpose. But when the author gets treated as a "Mars expert" due to his his "hard sci fi" novel, that's where I start having a problem.
