Highly trained or not, that sounds like a massive liability, both from the perspective of allowing people (who may or may not be thrustworthy) with weapons on planes, and the fact that firing a firearm inside a plane cabin is a pretty bad idea - a knife or similar would be at least as effective in a close-quarters situations such as a plane.
Finally, being a Sky Marshal sounds like the most boring job ever - I would imagine you'll end up with only people who failed at burger-flipping taking it + a few freaks... Not the people I would feel comfortable flying around with weapons.
Usually you get a seat assigned when you check in. You can often ask for a specific seat (for no extra charge) then also - but of course you won't get first pick.
Usually they go down the aisle with a "clicker" - usually not very covert. The plane doesn't take off before the numbers match.
On a flight I was on, the numbers didn't match up, so they went through the cabin with a list of all passengers, asking each of us to tell them their last name (which they crossed off from their list), in order to figure out who wasn't inside the plane.
The number of passengers with tickets is usually higher.
They don't compare the count to the number of tickets. They compare it to the number of people known to be getting on the flight, presumably these days from the number who've been scanned through security (in my airside days it was the number that had checked in at the desk, since this was before online check-in).
.. Which this device claims to be able to get through (the jetway is after the last ticket check). So the numbers may actually match up...
Yeah, I agree. Skipping the camera could make it lighter and remove most of the stigma - I for one would consider getting a google-glass like device which is display-only (and integrated/clip on to my prescription glasses). I honestly don't see any use for a tiny crappy camera attached to my glasses.
If I want to take pictures, I can use the cell phone in my pocket OR a real camera. Actually, many new system cameras have integration with smart phones, meaning that you can see the viewfinder, control exposure/focus/etc., and release the shutter using your Android/iPhone over WiFi. Something like *that* would be cool to have integrated with GG - use the controls on the camera, but have the viewfinder attached to your glasses.
True, I was mostly thinking of when turning without changing the speed of the flywheel, not when the flywheel is changing speed. However the flywheel being small & fast helps here - the stored energy is proportional to mass times angular velocity squared, while the angular momentum is mass times angular velocity (not squared) => the small weel would have less angular momentum for the same stored energy than the large.
My guess is that the angular momentum isn't that significant anyway, and for reasonable power outtakes, it really doesn't provide any problematic ammounts of torque. I'm sure the Volvo engineers have made some calculations about this:)
Counter rotating flywheels may elliminate most of the problems with net stored angular momentum, at the expense of creating likely larger problems with coupling two flywheels rotating in oposite directions to the drivetrain*.
* Aparently the test models have in effect two separate drivetrains - one FWD connected to the engine, and one RWD connected to the flywheel.
It certainly will:) Except with a horizontal flywheel, it would try to turn the car when ac-/de-celerating, and twist to the side when entering/leaving a steep hill. Could certainly make for entertaining speed bumps!
There are still tons of software being *written* in FORTRAN. COBOL I don't know, I don't work for a bank... But when I (2-3 years ago) where digging into the depths of the website of our local equivalent of IRS to try and figure out some piece of tax law, I found a link named "program for calculating tax" or somesuch. Clicked it - and got my screen filled with what I eventually identified as COBOL code!
Or, more likely, they have a stack of old computers with a win98 install, ready to swap out. The biggest issue is probably to keep all the driver disks around as well - installing old windows on old hardware is "a bit" more work than installing Linux, as you have to install a bunch of software after installing the OS, and the drivers are often hard to find via google...
To be honest, I've seen much, much older than that. I remember using a old IBM PS/2 (looked ~ like this: http://en.wikipedia.org/wiki/F... ) around 5 years ago. It was running some kind of instrument to measure the thickness of the oxide layer on Si wafers. Also remember having fun reparing Win95 boxen with a SCSI card connecting to some educational DAC box - which I eventually got to work win Windows XP (it supported the SCSI board right out of the box, and the new version of the LabView-esque software supported the ancient DAC!).
The mass of the flywheel is 13 pounds (~6 kg), while the whole device weighs 130 pounds (~60 kg). A lot of that is going to be shielding in case the rotor grenades.
I would guess the effect would be very much smaller if it is mounted so it's rotating in the horizontal plane (vertical axis), than if it's mounted with a horizontal axis.
Yeah, it would be nice if there was some way of *voluntary* declaring the type of a variable - i.e. state that this variable wil ONLY accept an Integer etc. - and that trying to store something else in the variable would raise a TypeError. Same goes for function arguments.
That could lead to (1) safer code where the mistake is caugth earlier and at the point where the data is stored as the unexpected type, not when you in a completely different piece of code do some operation on it which expects it to be a different type, and backtrace fireball ensues. (2) Potential performance increase
For me, when writing Python, (1) would be the main thing.
NYC has like 10 million people that take the train in daily LA, Boston and others also have millions that take the train to work
a lot of the cities in the US have less than a million people which isn't enough to pay for a train system
and even with NYC traffic, there is no smog here. i remember when i grew up there was lots of smog. but with the new cars being clean and all you can look at manhattan and there is no more smog hanging over it. the sky over NYC is clearer than parts of colorado ive been to
You don't need a million people to pay for a proper mass transit system - there are plenty of much smaller cities outside the US which have pretty good mass transit (subway, trains, trams, busses, and combinations). Honestly, most western European cities have decent mass transit.
La nouvelle immatriculation française qui est entrée en vigueur le 15 avril 2009 pour les véhicules neufs et le 15 octobre 2009 pour les véhicules d'occasion, se base sur le modèle AA-111-AA en vigueur depuis 1994 en Italie. Cette immatriculation est attribuée à vie au véhicule qui conserve donc cette immatriculation même s'il change de département ou de propriétaire.

No, I don't (it's not really a word I use very often/ever anyway) - but I honestly (unfortunately lacking hard data) I still don't really feel it is a "gender slur" even if may be mostly used against males - i think "bitch" etc. has a stronger aspect of gender in it. Maybe the reason is that for some words one (subconsciously or not) think that the gender is relevant for how the person acts and why that word is used, but for other words the gender aspect is only relevant for which word one picks? But then we're really discussing small nuances in language, where different persons may use slightly different definitions, depending on dialect/other language background and social background...
The two other you mention I've never heard anyone use. The "talking back to a female" stuff you mention is also pretty foreign to me - but then I'm from a culture where equality is quite far progressed. The nice thing is, it works both ways - i.e. it isn't expected that the male almost *always* picks up the tab when you're out eating etc. / fixes stuff / drives / etc., and there is no shame in the woman have a larger income than the man in a relationship. I appreciate that fact of our culture:)
Except the word "dick", used as you describe it here, doesn't really refer to a body part. The word can be used about either a man or a woman, describing "dickish" behaviour, which really isn't sex-dependent.
"Bitch", not so much. Calling a man a bitch would have other conotations than just being a bloody anoying idiot.

Do sky marshals actually carry guns onto planes, loaded, in the passenger compartment?
Quite common if you're not picking the most popular flights. Tickets are usually cheaper as well.
Got my own 3-seater many times that way, rise the armrests it's a quick flight to dreamland :)
Usually they go down the aisle with a "clicker" - usually not very covert. The plane doesn't take off before the numbers match.

But they do often carry a (sometimes huge) bag.
Clocks on the wall are maybe rarer, but tons of other devices shows a clock on their displays, which perform much of the same function.

According to the article, it holds the energy for ~20 minutes.

Even if they are women, they can still be assholes. Calling a man a bitch have other conotations.
