Nobody is talking about giving them access to nuclear weapon or stealth research. Shiva Star hasn't been used for military research in almost 20 years. It's been re-purposed for civilian research, and happens to be located on an AFB for historical reasons. If this is anything like other civilian research in the US, it involves many foreign nationals whose allegiances are far more questionable than Canadians.
Because this Shiva Star device is located in an Air Force base, security restrictions prevent any meaningful cooperation with a non-U.S. companies.
We have a problem with Canadians because of security restrictions? WTF - NORAD is a joint US-Canadian operation. The 2nd in command is always Canadian. If that's not giving Canadians access to important military operations (specifically USAF no less) then I don't know what is.
Or at least they're trying to. I wonder how good at it they are. The stuff described in the article seems mostly like sophisticated malware, which requires brains but no sophisticated hardware. That sort of thing is a traditional Russian strength, but I wouldn't be surprised if China is good at it too. It would be interesting if we could compare the capabilities.
"invest personal time in the children" != "being overprotective"
Not necessarily the same thing. Nevertheless being overprotective does require time. Hence smitty_one_each's comment criticizing parents for not "invest[ing] personal time in the children" doesn't make sense. What's needed isn't investing more time, but investing it in a way that's better than being overprotective.
You have an awfully strong reaction to me pointing out a nonsensical statement. I have to wonder though, what kind of teenager can't sneak out without their parents figuring it out, especially if their bedroom is on the 1st floor? Teenagers must not be very clever these days - probably comes from too much social media. Lastly, if she was "murdered by her two best friends", I suggest that the bigger problem was her choice of friends.
Most people are a little less extreme with their kids. That, and kids and teenagers being much smarter than dogs, means it requires serious involvement (albeit not of a productive variety) to keep them chained up without physically chaining them.
They don't have the power to say how your kid gets to school
No, they don't. She walks.
or how they get home
If she tries to walk home she'll get in trouble. My wife and I can scream and fight. Hell, we could get a lawyer (people sometimes have to do that when it's a serious issue). Could we fight city hall? Yes. Is it worth it for this one minor stupidity? No. It'll make her life more difficult. At least next year she gets to walk home.
. ..to admit to lousy parenting and invest personal time in the children.
Huh? Talk about a knee jerk response. "Investing" too much time (i.e. being overprotective) is exactly what's being blamed here. I don't think social media is a major social problem, but I do think parents are overly protective. What we need is a little more neglect, like I enjoyed.
And people eat it up. My 10 y.o. daughter isn't allowed to walk home from school, which is two blocks away. She hates it because the bus takes 40 minutes instead of 5. We live in a low crime area, and we've asked if we have to sign a permission form or something to allow her to walk home. Nope, can't do it. District policy. Child must either take the bus or be picked up by a parent.
It's nuts. I, and everyone else who lived too close for a bus, was expected to walk to and from school by ourselves when we were in kindergarten. There were crossing guards for major streets. People say "the world isn't like when we were kids". They're right - it's safer! (that does depend somewhat on your age, but things have been getting safer for years).
I tell my daughter to walk to school. She complains it's cold. I ask "did we forget to buy you a warm coat? Hat, gloves?". Nope, all is in order. "So get out and walk!". I feel a little weird because my neighbors drive their kids to the same school (seriously) or walk with them. I wonder when Child Protective Services is going to pay me a visit.
Even younger than that. My wife is fortyish and remembers it. It was common for parents to basically kick kids out of the house so they could have some time to themselves. Neither I nor anybody else I know resented it. It was basically "go out and play with your friends". Who knew we were all abused and neglected children?
No, no, no! Remember the scene the "Life of Brian" where he tells the crowd "you are all individuals", and they respond in unison "we are all individuals!"
and for a higher voltage you go line-to-line, which is only 208V
That's not how they do it for residential (at least in my neck of the woods - not sure if it's universal). It's split phase. The secondary of the transformer feeding your house is single phase 240V with a center tap connected to neutral (nominally an earth ground). 120V lines are between either side of the secondary and neutral. You get 240V by connecting to both of the "hot" sides of the secondary (i.e. you don't use the center tap).
Which would do what? As I mentioned, a resistance that's perfectly acceptable as a wiring drop (especially for a long line) would, if concentrated at a bad junction, cause a fire. You can't tell the difference at the load end. Therefore, in addition to the initial measurement of source resistance, they look for the sort of short term fluctuations that are characteristic of a bad junction.
The U.S. has had time to upgrade their infrastructure
Are you kidding? Imagine a power company telling its customers that they're being "upgraded" to 240V service, and therefore all the electrical equipment they have will be trash. Moreover, all wiring, outlets, etc. in their home has to be replaced.
120V is not an "infrastructure problem". The only ramification is a little more copper to wire up a home. 120V comes from the max practical voltage for a carbon filament bulb. Europe, being about 20 years behind the US in large scale electric power distribution, was able to choose a higher voltage, but one that was still limited by the then state-of-the-art in metal filament bulbs. If you were to choose an optimal household wiring voltage today, who knows what it would be. Maybe 350V would be better. Moreover, for large loads where 240V makes a significant difference (e.g. electric range or dryer, CAC, etc.), American homes have 240V lines.
His requirements? Try the National Electrical Code requirements, which are legally required by most state and local building codes. A 50A line that can't deliver 50A is in violation, and shoddy wiring like that is a serious hazard, regardless of whether you charge a Tesla with it.
the terrible wiring was fine until a Tesla was plugged into it
The terrible wiring was fine only because nobody had been using it at rated capacity. And no, you shouldn't have to derate a 50A line. 50A means 50A. NEC is conservative, and if followed correctly you could in practice draw more than 50A (though I certainly don't recommend it). Moreover, Tesla already had one mechanism in place to prevent this sort of thing (cutting back the current if there was excessive voltage drop), and this is simply adding another. At what point do you start blaming the wiring for not being able to deliver the rated current?

You forgot to tell them to get off your lawn.
Because prostitution can be an honest profession.
Most teenagers are a lot less clever than they think.
Yes, but the same is true of parents.
Ok, I'll change my position :)

unless they aren't being rational at the moment of the decision
Even Mr. Spock suffered from pon farr every seven years. In human teenagers it's more like every seven minutes.

You can chain a dog up ...

she was allowed to sneak our of the house
Think about that one.
That's child abuse.

I've heard of strong reactions against social media, but I didn't think it went that far.
We are all the product of our environment.
No, no, no! Remember the scene the "Life of Brian" where he tells the crowd "you are all individuals", and they respond in unison "we are all individuals!"
Makes little sense to me.
You're obviously too intelligent to get very far in intelligence work.
Someone included the flag at some point because they thought catching on fire was something the user might occasionally want.
Hopefully it came with a user warning like "do not use if arson is illegal in your area".

Which why that word continuously was in there.
