"How is this "huge?" What the hell are you going to do with it? Someone tweets and uses an exclamation point, so you... what now?"
 
You look at more of their tweets until you're 98% sure. Then target your advertising.
 
GONG! Thanks for playing.

How can Wired write an entire article, and slashdot write a summary, all about a website, and nobody includes the link to Kahn Academy!?? Geesh

This looks really cool and certainly puts out some impressive noise. But it's hard to get excited when there's no info on horsepower, MPH, time to 60mph, or any other interesting facts.
But mostly watching him cruise at 8mph is just frustrating.
 
OK dude, very cool. You put a ton of effort into building something really neat. But with all that engineering and noise it needs to do more than act as a lone parade float. Would love to see you racing it through the Nevada desert....
 
Kudos for taking it this far of course and making us hungry for more.

Cost efficiency assumes the trains are full. They won't be. Not here in the states. They'd be empty.
 
The biggest problem with huge trains is filling them. You could build an awesome next gen rail system here in the states but nobody would ride it. Accept for the corridor from D.C. To NYC the trains would be empty. There just aren't thousands of people every day that need to get from St. Louis to Sacramento. Maybe a couple plane loads on a busy day. But that's it. There ARE many thousands of people all going someplace different though. What rail needs to replace in large part are CARS. That means we need to be able to hop on in lots of places, and tell the thing to zip us across town. Think Street Cars of the future. If it picks up nearby every 15 minutes and takes you right where you're going you can also give up quite a bit of speed. Long trains full of a thousand people, boarding, stopping, starting, going across the countryside, stopping and going again to accommodate all the people, it's a nightmare and when we finally arrive we have to rent a car to get around!

Small single car rail is the answer. Hop on, go where you need, across country or just across town. 100mph is plenty. The power goes in the rails, the "brains" go in each car, not some big switching station.

I never understood why they build high speed "mag-lev" rail with huge cars and long long trains. They have to fill all those cars, with tons of people all looking to go the same place at the same time.
 
Mag-lev trains get very little benefit from being big and long. Small individually switched cars like this make much more sense to me: http://www.megarail.com/pr/library/2002/mar/20maglev/

Nobody's single-point-of-data scenario matters to the argument at hand. Not yours either. What matters is the actual change in the number of impaired drivers on the road. That's it.
 
From there you might possibly get a better idea of what types of scenarios occur more often than others.
 
Maybe the simple of act of checking the app is enough that more people tend to wait longer and order water. Maybe the act of passing the app around in the bar initially trends toward more sober drivers as people are reminded publicly, but once the novelty wears off, it trends back to drunks taking back roads? Who knows? To sit there and argue by anecdote is a waste of everyone's time.

Owning and controlling something is fine and dandy. Literally trying to own and control the photons that bounce off of your property is too ludicrous for words.

Just because you can, doesn't mean you should.
 
Snow days are healthy. By Saturday it'll be muck, or ice, and the kids will be stuck inside, yet again. And since it's May, let's not forget it's dark by dinner time in the winter. Let the kids play outside, for their own good. It's only a few times per year.

That's not a reconciliation. That's an unfair theory that assumes the extra grey matter is unwanted. He could just as easily theorize that "Some mechanism is helping these brains keep more of their flexibility and childlike wonder and curiosity." OR "This extra grey matter might allow mature brains to better function in a chaotic environment, whereas a normal adult brain tends to get "flustered" when routines change."

  Of course I just made all that up, but you get the point. He begins his theory-making by assuming part of the brain is unwanted. Try again without the bias buddy.

Please, just let me shop from my phone and then pick it up.
 
Who am I kidding? I'd be thrilled if they could just figure out that the Frozen aisles go last.

The real questions are:
  How much can we trust the various "Off" switches for the multiple "Location Services" on our mobile devices?
 
    How much responsibility do companies have to make sure their devices' default settings don't "invite" crime and invasion of privacy?
 
Who checks to keep these businesses honest?

...Also irradiation with high energy ions could be useful in improving the interlocking of the graphene layers...
 
If my calculations are correct, a 62.4% increase in efficiency would be gained by simply reversing the polarity and then bombarding it with an inverse tachyon pulse.

I wonder if they intend the Oasis metaphor to extend out to the desert around it.
 
Or, to mix metaphors, are they basically saying "Nothing will change around here, but we'll build you an enclosed sandbox to shut you up. SURE we'll listen to ideas."
