Again, AMOS-6 was not in any way owned by Facebook. They had simply signed a contract to lease a significant portion of the Ka-Band payload pointed at sub-saharan Africa. But don't let facts get in the way of your hate.
With the exception of a few isolated communities (and the occasional voltage support from Burrard Thermal in Vancouver), British Columbia has run on hydro power for decades.
For larger buildings, the first thing they'll do is shut off the power.
The NEC includes what is known as the "6 throw rule." You must be able to shut down the power to a building by throwing no more than 6 switches/breakers on a single panel.
What's with these summaries? Facebook had nothing to do with the spacecraft, other than the fact that they had an agreement in place to lease a significant portion of the Ka-Band transponders on the satellite.
The FTS (Flight Termination System) is on the side of the rocket opposite from the strongback. The initial fireball was immediately adjacent to the strongback, so it's unlikely to have been a misfire of the FTS.
That said, as big as today's fireball was, it was just that, a fireball. It wasn't a detonation (likely until Amos 6 hit the ground and and the Hydrazine went off). The failure mode you actually want in these kinds of situations is to ignite the mixture before it mixes adequately to detonate. As such, the fireball was pretty clearly sub-sonic, and thus wouldn't be that hard to get away from assuming suitable detection and ejection systems.
Technically speaking, the booster that will be used for SES-10 hasn't been re-used either... it's only been used once. At the end of the mission it will have been reused.
The explosion actually occurred during tanking. The point of a static fire test is less the actual testing of the engines, but as an all-up dress rehearsal prior to launch. It's intended to find any snags in fuelling procedures/equipment, communications equipment, procedures, and so forth. Unfortunately, this time, the snag was catastrophic. Additionally, the actual ignition with the rocket restrained is very brief. It only burns for a couple of seconds before being shut down, basically similar to a pad abort.
Delta IV Heavy does a WDR (Wet Dress Rehearsal) where they do the full countdown, including loading all the propellants (hence "wet"). The only thing they don't do is actually ignite the engines. As I recall, a similar test was done with the Space Shuttle, including igniting the SSMEs (but not the SRBs obviously).
Anyhow, to your original point, the failure occurred in the second stage, prior to first stage ignition, in a procedure that is similar for most rocket manufacturers out there.
Satellites are already required to be able to de-orbit.
Well, depends on the orbit. Geostationary satellites will never, ever de-orbit. That would take almost as much fuel to get up there as to get back down again, which makes it non-optimal (rocket equation and all that). However, when the spacecraft goes end-of-life, they are required to raise its orbit by 160km or so, vent all remaining propellants, and blow fusable links to permanently shutdown the craft. That keeps it from exploding, and leaves it as being easily trackable.
Vancouver, BC to Chelan, WA, typically over the North Cascades Highway. Plus the car gets parked for a week in a lot that doesn't have any charging stations.
I would love to switch to an electric vehicle, but the reality is that after moving into the city, I might go weeks at a time without touching my car. Also, I tend to make 8 or 10 long-haul trips a year, which wouldn't be feasible in even the best electric vehicles. Yes, I could rent a vehicle for those trips, but then in my situation, I'm renting the vehicle just to drive 500km, park it for a week, then drive the 500km home.
If I wound up in a family situation where we became a two car family, absolutely, an electric vehicle would make sense for one of them. On the other hand, my car (a 10 year old Jetta TDI) is still extremely reliable, and very cheap to operate, and still one of the more efficient vehicles on the road.
Have the city maintain a key piece of your internet connection?
It works pretty well in Douglas and Chelan counties in Washington State. There, the PUD maintains a fiber infrastructure that covers nearly all the homes and businesses in all the various communities. They themselves do not provide the service (be it TV, Internet, etc...). As a customer, you have the choice of 8 or 10 different ISPs who all have access to the fiber. If you're a business you can also get transit through Level 3 or Zayo.
As far as repairs go, the PUDs are just almost as quick to repair any fiber breaks as they are to repair issues with the power grid.
And doesn't know what they're talking about. As long as Mars isn't obscured by the Sun (which also happens every 26 months) the communications with the probes around Mars continues unhindered.
Until this year, you could show your registration card, a bill with your name on it, your photo ID, or you could swear an oath to Her Majesty and be done with it (the latter took some time).
Take the choice of election technology, ballot design, and security out of the hands of 5,000 different jurisdictions, and replace it with well-designed, thought-out, and implemented hardware+software that a dedicated, concerned group of experts is responsible for -- that's what this would take. And is impossible.
Or, you know, do what Canada does. Keep the voting process pencil and paper and count ballots by hand. Canada typically has the results in from a general election within 4 or 5 hours of the polls closing, and recounts rarely change the results by more than one or two ballots. Every ballot is counted at the polling station, and every candidate has the right to have scrutineers present to witness that counting.
Yes, Canada has 1/10th the population of the US, but on the other hand this is a problem that scales linearly. You have 10x the population, so you have 10x the polling stations, 10x the returning officers, scrutineers, etc... It works, it's reliable, and is pretty resistant to any kind of interference. Any "attack" (in the computational sense) would have to be carried out on a widely distributed basis.
They would have lost in court. had several legal defenses prepared, one being that it was statistically possible to identify individuals in randomized data by making repeated queries and varying the area covered
Clearly you've never actually worked with the census data. As part of one of my university courses, I queried the data set for information related to national origin and religion for a particular neighbourhood. You can not define the area arbitrarily, it's broken up into minimum sized zones to prevent the kinds of attacks that you are talking about.
The folks at Stats Canada are smart. You, clearly, aren't as smart as you think you are.
Often a 9600 baud modem, but defaults to the slowest speed: 1200 baud
Transactions are such small amounts of data, that 9600 (and 1200) are actually faster than say 33.6 or 56k. The training time for 1200 (and 9600) are significantly quicker than 33.6). I'm showing my age here, but back int he day when I ran a BBS, I actually had my mail relay setup to push outbound echomail at 2400 rather than 33.6 as it saved probably 10 seconds or more per email.
If you are going through the border, they can refuse you entry if you don't comply.
They can only refuse you entry if you are not a citizen. To the best of my knowledge, all civilized countries, including the US, have an absolute right of return. If you are a citizen of that country, you can not be denied entry into it. They can deny your stuff, and make your life miserable, but they can not refuse to let you in.
What good would having the phone do, unless it's unlocked?
Depends on what they wanted it for. The more likely thing is they took it back and swabbed it for drugs. The phone was just a frequently handled item that would likely contain narcotics residue if it was being handled by someone who was running drugs or similar. The phone doesn't need to be unlocked to swab it.

Also, don't forget the humble Felis Catus.
The whole point is that regular soap and water are just as effective as those containing these antibacterial agents.

What's being launched on a reused rocket: SES-10
Technically speaking, the booster that will be used for SES-10 hasn't been re-used either... it's only been used once. At the end of the mission it will have been reused.
It blew during or shortly after a static firing

They're lying, or in one of a few very specific buildings... the rest of us suffer with plans as bad as what's south of the border, or worse.
