...and, matterafact, I just saw that Amazon is doing exactly that: compensating their delayed customers with giftcards. Apparently it was the merchants, not the carriers, who were guaranteeing delivery dates. Good on them.
That being said, having your gifts arrive a little late falls in the First World Problems category. Get over it.
True, but so is a corn futures contract. If you sell me one and the corn doesn't show up at the warehouse, I'm not gonna let you off the hook because you had a dry year...and Fedex/UPS should be expected to compensate their customers some way. It won't kill them to knock something off the next shipping bill.
the delay has nothing to do with volume and everything to do with bad weather.
Well, a Fedex I received from my daughter calls BS on that. The tracking log showed that it went aboard a delivery truck on the guarantee date; returned to the shipping center that evening; and went back out the next morning.
As fisted said, you apparently fell for a gag, but no biggie. Since you're interested in the subject, here are a few additional details.
Vacuum itself has no temperature, because temperature is a measure of the motion of particles, and there are none. Space is not a perfect vacuum, having very roughly one particle of one sort or another per cubic meter, and in principle you could calculate a temperature based on their motion, but it would never exchange any meaningful amount of heat with an object.
Vacuum will not conduct heat either, and without conduction there is also no convection, so the only means of heat exchange left is radiation. Any two bodies separated by vacuum will exchange heat in proportion to the difference between the fourth powers of their respective temperatures -- and this is where a very big variable comes into play.
Excluding the Sun and Earth, the rest of the universe acts approximately as if you were surrounded by a black surface at a temperature of only 3 kelvins -- almost absolute zero. That means you will lose heat very fast.
OTOH, the Sun approximates a blackbody at nearly 6000 kelvins. That means if you're exposed to it, you'll absorb heat REALLY fast.
So whether you're in sunlight or in the shade makes a huge difference. If a satellite receives more heat than it radiates away, its temperature will keep going up, and vice versa. The designer has to do a lot of tricks to keep the temperature under control. You can get rid of excess heat with radiators that expel heat into cold space on one side, and have a shiny surface on the other side to reflect away what arrives from the Sun. (car analogy)The coolant pumps on the ISS do the same thing the water pump in a car does: transferring heat from the interior to the radiators (/car analogy).
The Kalashnikov is designed to loose manufacturing tolerances, instead of precision fits. That results in some loss of accuracy, which isn't a big problem because military small arms are seldom used for precision fire anyway...in return, it's easy to clean; it continues to work with an impressive amount of dirt and corrosion; and it's easy for a very lightly trained soldier to operate. It's also very cheap to manufacture.
In other words, the ideal product for cashing in on Third World conflicts.
In the English Engineering system of units the primary dimensions are force, mass, length, time and temperature. The units for force and mass are defined independently
the basic unit of mass is pound-mass (lbm)
the unit of force is the pound (lb) alternatively pound-force (lbf).
In the EE system 1 lb of force will give a mass of 1 lbm a standard acceleration of 32.17405 ft/s^2."
...which is why I used the word "archaic". Yes, kg and newtons are much better units, although there are those who try to corrupt the setup by defining a "kilogram-force" as the weight of one kg.
Incidentally, all the Imperial units are now formally defined in terms of SI units; the pound-mass is defined as 0.45359237 kg. The kilogram is also the only SI unit still based on an actual physical object; there's a platinum cylinder in a vault outside Paris that by definition masses one kg. And even that is on the way out...within a few years the kilogram will be based on the Planck constant.
First, the pound is a unit of mass as well as a unit of force, thanks to our archaic English unit system. You can keep them apart by using pounds-force (lbf) and pounds-mass (lbm).
Second, the effect of gravity at the height of the ISS is about 88% of what it is at sea level. If it has a mass of 780 lbm, the gravitational force on it will be 689 lbf.
Asimov didn't "lay down laws". He wrote fictional stories about a society in which legislation, driven by public concern, imposed laws on the robot industry.
Are those laws a good idea? Maybe...but you can't "violate" them, because they aren't laws in any jurisdiction on earth.
Heat pumps work best into approximately equal temperature differentials for heating and cooling. Lots of them in Florida, almost none here in Colorado.
There's a technique I've noticed lately that seems aimed at defeating the fast-forward. In the middle of a string of five or six commercials, they insert a teaser for the program that's running, in the hope it will make you click "Play" and get ambushed by the next commercial.

It was logged as "On vehicle for delivery" twice, on two consecutive mornings.
Isn't that what I said?

So why haven't all you smarter people gained control of the government and done something about it?
Here's a paper towel for you.

In reference to the Scud missile, they used a much less delicate term...
That is a career ending move.

Colorado is mostly gas heated, though Denver had a period in the Seventies when gas lines were scarce and some subdivisions went electric.
Well, that's easy to fix. Paint your incandescent bulbs black and they'll be 100% efficient at heating.
Heat pumps work best into approximately equal temperature differentials for heating and cooling. Lots of them in Florida, almost none here in Colorado.
Helium, neon, argon, and radon are probably the ones most people have heard mentioned
Everybody's heard of krypton, although most of them think it's a planet and Tom Clancy couldn't spell it.

Would you prefer the Russians sold their warheads on E-bay?
They laughed at Robert Fulton...
And they laughed at the Wright Brothers...
And they laughed at Bozo the Clown.
The WTF blog once featured a tale of woe by a contributor about his interview with a headhunter:
-Why do you want to change jobs?
-My employer wants me to become a COBOL programmer.
-So, you don't like to learn new things?
