Not just once! I regularly see listings requesting 5-8 years experience with ASP.net, PHP5, or Ruby on Rails, 3-5 years experience administrating Windows Server 2003 or Fedora, it goes on and on.
What happens when (as with me) I'm young and not terribly experienced in general, but I've been using technologies since they came on the market? Do I apply and disregard their asinine requirements? Do I assume they mean general experience with that sort of technology? Do I assume they're obviously nontechnical and that the wrong people are running tech recruiting for them?
Amen. Would grandparent poster rather have society conform to him, or have the choice to not have hearing problems any more? For that matter, I want hearing improved above normal.
Same problem with impactors as with explosive, really, although I suppose you can just sort of float them up there, since the relative velocity would be effective. You'd need ten metric tons of impediment (I'm assuming for practicality that it would be "at rest" relative to the comet's velocity)
I see the problem as being not so much stopping the comet, as the fast reaction time needed to put the projectile up. It takes months and months to find a good launch window for geosynch sats, let alone things like the Cassini probe. You're talking about trying to hit an object half an AU away with three months notice (assuming 6 months of warning)
The amount of energy it takes to get a gasoline tanker worth of energy to a comet a few months before impact is very, very large.
Also, you're assuming that 140,000 KWh is translated into productive thrust, which again is not precisely accurate. In space you'd need the oxidizer, which for gasoline would mean approximately 8 tanker trucks of liquid O2 needed to oxidize.
Even if you're using a higher Isp engine like an ion drive, you'd need to apply at least 140 kilowatts for a month.
Addendum to that math: Not the entire US electricity budget, but the entire US energy budget, including direct usage like gasoline, natural gas, and heating oil.
Composition of cometary objects isn't as important as their mass, in terms of protecting Earth from impacts.
Really, the sheer kinetic energy inherent in hyperbolic objects is so large as to make the thought of deflecting them silly.
For example, a cometary object 1km square would weigh a billion metric tons, and carry ~48 quadrillion Btus (or 1.41117626 * 10^13 kilowatt hours, a number so large it's silly), which would power the entire US for around six months if converted to electricity.
Basically, all we can do is hope. There's no imaginable engine that could be built on earth and sent to a comet in time to change it's orbit enough to avoid earth.
Also, to add more, spheres show a very interesting behavior in different fluid flows: They're almost self-parachuting.
"The drag coefficient for a sphere is given with a range of values because the drag on a sphere is highly dependent on Reynolds number. Flow past a sphere, or cylinder, goes through a number of transitions with velocity. At very low velocity, a stable pair of vortices are formed on the downwind side. As velocity increases, the vortices become unstable and are alternately shed downstream. As velocity is increased even more, the boundary layer transitions to chaotic turbulent flow with vortices of many different scales being shed in a turbulent wake from the body. Each of these flow regimes produce a different amount of drag on the sphere."
To summarize that, basically at low speed, spheres form stable airflow which reduces drag substantially, whereas at high speeds, the sphere creates an uneven "wake" (much the way you might imagine a curveball behaving)
It depends greatly on a couple factors: Coefficient of drag, surface area, mass of the object, and the density of the air it's falling in.
If you assume that the object can survive the freefall from space, then the air changes density enough that it would slow to the terminal velocity of the object at approximately sea level regardless of how fast it was going (within a reasonable orbital velocity)
So to summarize a bit, it'd be easily possible to design a rough-surfaced sphere that could slow to well under 100mph. Just think of a ping-pong ball or a beach ball!
Eat more. If you make a concerted effort to increase your portion sizes, you'll gain weight.
I was 155 a year ago, and I'm 185 now. It's just a change in the mind, and a certain amount of adaptation of your stomach (which varies the point at which it registers 'full' depending on how much you've been eating lately)
Depends on the volume in the vests. With the right kind of microtubules and a high flow rate, you could keep the cooling down to a pound or two of water, which really isn't terribly much when considered next to a 12lb rifle and 20lb armor.
I still think that this is an artifact of the interfaces we're using. As it currently is, we can't 'reach' behind things with the mouse, given that it's a 2d interface. I'm thinking of things like being able to dive "into" a stack of data with the interface and grab the particular one you need, much as you might select a seldom-used object from behind other objects on a shelf.
Not to mention being able to physically interact with objects in 3d, for example, being able to do modeling by molding virtual clay instead of drawing intersecting primitives, being able to stack and reorder documents and files in a presentation, being able to make larger or more important files feel 'weighty', being able to link files by 'hooking' them together, compressing files by squeezing them, paging through documents by 'turning the page' or 'flipping the book' rather than pressing the page down button.
I could continue on, but these are just initial thoughts. Obviously you have to avoid 'gorilla arm' such as that resulting from touch screens, but that could be offset by allowing the interface to be a 'rest' for the arm when not in use.
I think this is the key to future interface design: Not the virtual representation, so much as the interface devices. As long as we're restricted to a 2d mouse and a set of binary keys, the different metaphors for the software are moot.
Assuming we get something with positioning in all the dimensions of space (or at least, more than two degrees of freedom of mice) then you can start having interfaces which utilize those spaces.
Of course, right now we navigate 3d spaces in video games fairly effectively, but it's a full-concentration task, using both hands. Which is not exactly ideal for something you multitask in, perhaps? As well as containing the restrictions of a physical 3d world such as gravity etc. Perhaps descent would be a better model.
That's not accurate, he's talking about the exchange rate, Rs 100 = $2.27 USD
However, cost of living indexes place most cities in india at the very lowest end. New Delhi supposedly rates 45% of the adjusted average based on New York City. So, roughly speaking, you can buy twice the standard of living in India as you can in the US, roughly the same way you can buy twice the standard of living in NYC as you can in Tokyo.
Of course, cost of living is a largely arbitrary measure, in general.

You mean more like:

void take() {
break;

catch (EmployerException hell) {
goto hell;
}
(and yes, java doesn't have gotos...)
Try a break. /coding joke
I was thinking another method: Print them out. Ship a thousand or so reams of paper with all of the requested data on them in very, very tiny font.
Good lord, I've worked jobs where we pulled a 17 hour straight shift, went home, and came back six hours later for another 10 hour shift.
Remember, you live in a 'scandanavian liberal paradise' which implies a higher level of socialism than the US. Here, people often work 60 hour weeks.

No, no, the cliche would go like this.

But I also don't have an automobile. If I ride several hours in an automobile, then I hop on a horse, there's going to be a jarring 'blech' reflex.
Solution: don't buy an automobile or motorcycle.
