Comment Re:"you don't have to be very accurate" (Score 1) 255

A nuke hitting somewhere in your country at more-or-less random is still a nuke hitting your country.

Sure, you might luck out and have it land somewhere completely uninhabited. But then again, you might not. And you still have radiation and fallout issues.

Not to mention the whole 'now we either MUST nuke them back, potentially kicking off a war with China, or admit that deterrence is a huge bluff, and watch everybody rush the tech tree to nukes.'

In this context, think of 'a reasonably stable orbit' as 'an over-enthusiastic ballistic launch.' Or, think of a ballistic launch intended to land on a continent on the other side of the planet as 'something with a really short orbital period.' In other words, if they can get something that high, they can put it slightly less high, and have it come back down.

OTA channels = 19.38 Mbps (max)
2 channels = 38.76 Mbps = 4.845 MB/sec
1 Terabyte SSD = 1,000,000 MB
1,000,000 / 4.845 = 206,398 seconds, or 2.3 days
Nand flash write cycle life : 10,000

Total life 10,000 * 2.3 days = 23,000 days or 65 years

If you don't like the assumptions, feel free to make your own, but I think it's clear that write cycle life isn't going to be the limiting factor.

Comment Re:It were the russians (Score 1) 62

It's been a while since I read my 80s techno thrillers, but the idea was a nuke sub (or mobile land-based launchers, in theory, but I don't think they ever bothered with that) would use GPS to get an exact fix on where it was, and input that into the missiles as their start point for inertial navigation. This allowed for 'first-strike' capability, which required silly amounts of precision to hit hardened launch sites on short notice, before enemy C&C could authorize retaliatory strikes, and simultaneously denied the enemy the ability to perform a first-strike on you, as first they'd have to find your hidden SSBNs.

The GPS system was originally called 'NavStar,' as it was intended as a navigation aide. The missiles themselves were intended to be as autonomous as possible after launch; after all, the GPS satellites were easy to find and destroy, what with them broadcasting their locations.

Comment Re:H-1B visa are not a free market (Score 1) 243

And the same is true of the states. Trying to cross the border from Canada into the States to start a job, transferring a Canadian company to it's brand new American owner, and getting stopped. Should have been a thirty second conversation with the border folks, under Trade NAFTA. Nope. I was trying to steal an American Jerb, and that was that.

The company started to lawyer up, but I declined to continue the process, and stayed in Canada. What can I say, I was young, and foolish. In retrospect, I made the correct choice.
