Thanks to a prosthetic knee, I get the "human touch" every time I fly. That's after a trip through the pornscanner and taking out all of my electronics and startingt them up, of course.
As for the kiosks -- if you know what you're doing, the last thing that you need is the kind of condescending "help" that gets in the way of getting your freaking boarding pass.
Yes I know they probably don't....but they "should"
I've been fired for taking off a weekend day that I'd told people about for years (first weekend every November) that suddenly became a "be there" -- announced after I'd already gone out of data reception.
So, yeah -- we might as well laugh.
The United States exported about $106 billion worth of such goods last year.
It's one thing to export $106 billion more than you import and quite another to export $106 billion while importing $250 billion.
A good rule of thumb is that if an article doesn't explicitly tell you that it's a net export, it's because it's a puff piece with a bias and the truth would harsh the whole slant.
Yes, lots of educated (and wealthy) citizens create markets for better services in cities. But decades of surveys of companies planning locations and of educated workers considering relocation tell us it works the other way around, too.
States like Arizona and Texas that base their plans for attracting high-wage (lots of educated employees) employers on cutting taxes usually do it by also slicing schools and other services.
That seems to be working in places like Austin, where the city makes up for the lack of State support for education (or actual hostility to it) by cranking up local sales taxes -- which fall more on the poor than on the affluent. Which is a sweet deal if you're making serious money as a twenty-something in technology there, but might not look so good when you have kids and you're looking for daycare and primary schools.
We're doing the experiment. Check in again in ten or twenty years to see which way the arrow of cauality runs.
Ask yourself: what does the TSA do to detect iron oxide and aluminum? (Much less magnesium! MacBooks, anyone?)
They've known about this for years. They have quite competent "red team" people who think up possible threats, and they're not remotely so stupid as to believe that the Bad Guys can't think up this kind of thing themselves. Ask a classroom of sophomore-level engineering students to come up with ways to get plane-killers aboard and this is one of the first ones -- although it's a very, very long list.
However, stopping thermite from getting onboard is going to be way more of a public inconvenience than their mission statement allows.
Most of the AGW activists are pursuing political agendas that have a limited connection to AGW. Here are some questions to ask yourself - Why are AGW activists not actively pursuing increased hydroelectric power? Why are AGW activists not actively pursuing increased nuclear power?
Mostly because they're not interested in mandating specific aproaches. Instead of the old-fashioned approach of Nixon's EPA, they're going for market-based solutions: putting a price on carbon emissions, for instance. Or a conservative variant on that, George H. W. Bush's cap-and-trade mechanism updated by John McCain for carbon dioxide.
Or the most recent study's proposal: just eliminating taxpayer subsidies for fossil fuels would get us halfway to the 2-degree target.
we need to try to break the association between identity and factual beliefs on high-profile issues
I suspect that there are more than a few groups and people with influence who disagree. And from the evidence, they're likely to continue to get their way.
The main reason that trucks replaced rail was because of the
.. enormous subsidy that the USA put into highways starting in the 1950s. It was ostensibly to create a transportation system that would not fold up following a nuclear attack, but like all such things it took on a life of its own.
First off, the ping rate for auto traffic is an enormous number of pulse durations or return times -- the radar will ignore returns coming back more than a couple of microseconds after it sends its last ping, and only needs to ping every few tens of milliseconds. That's a window of less than 0.1%.
If a car detects a return in a "forbidden" time slot, it can just switch to not using that frequency. Or use the kind of random backoff that Ethernet has been using now for forty years.
And that's just two solutions.
