Comment Re:Good luck on that... he won't appear (Score 2) 304

Regardless of my actual ethnicity or religion, if my last name ended in ...berg I wouldn't go anywhere near Iran.

"Berg" is a common German family name. Both the Germans and the Iranians are the Aryan race. Thus, the "Berg" families would be closer to the Iranians than most other westerners.

Note that the nation changed its English name from Persia to Iran at the insistence of Nazi Germany, to identify itself with Aryan pride (before the second world war). The words Aryan and Iran are cognate.

A properly implemented auto-save feature does not overwrite the original document; it saves a secondary copy, to be used only if the system crashes and you need to recover your edits.

This is what MS Office does. Of course, no one here uses MS Office, so that's not much help...

This is what Open Office and LibreOffice do as well.

Comment Re:Does it really matter? (Score 1) 203

Correct me if I am wrong but couldn't that have been inertia?

No, not inertia:
1/2 * m * v^2 = dH * m * g

Simplified for this particular case:
dH = v^2 / 2g

Note that it doesn't really matter in which direction v is pointed, and if he is using wings to convert horizontal velocity to vertical velocity, he will also suffer a large friction penalty.

Thank you, I was unaware of the Tundra orbit until now.

Molniya orbits typically do not have the optical resolution to find smaller objects that are in motion, due to their altitude. I don't know if the current generation is capable of spotting an airliner, especially in an area that is not of current interest where additional system resources would be spent. However I doubt it!

I would suspect that Tundra orbits would have worse optical resolution than Molniya orbits, seeing how they orbit even farther out than do the Molniya orbits.

The why not is an easy one - spy satellites are put into orbits which cover the likely hotspots for their use, and changing those orbits lessens the useful life of the satellite fairly significantly.

Oh, and no one really wants to give away the true capabilities of their spy satellites...

Not true at all. Reconnaissance satellites are usually on very low near-polar orbits, completing an orbit in 60-90 minutes. As the Earth spins below, they cover the whole thing. However, the sensors onboard collect more data than the available bandwidth, so they do not transmit the data about uninteresting areas, such as over the open ocean where nothing of interest is expected to be.

You could make a point for storing a 48 hour buffer of all untransmitted data for later transmission if it is deemed necessary. However that has it's own set of problems, such as energy budget, cost and weight, and being susceptible to problems such as cosmic rays flipping bits.

How much online advertising has your dad clicked on in the past decade? In other words, your dad is for Gmail a leech, not a product for Gmails advertisers. They would be glad for him to switch.

I firmly believe that the UI changes are designed to reduce our natural ability to mentally block out the advertisements on webpages. When the UI changes frequently, we must always examine the whole page (ads and all) to find what we need.
