if you tell a lie often enough....
... then some nutjob, who thinks he's the last sane person on the earth, will fill in the details of how the lie is true, and then believe it absolutely and unconditionally?

News Flash: 10,000 Slashdot accounts compromised in phishing scam. Most common passwords were 31415 and 0xdecafbad.
Affected users have been placed on an isolated network where they can't do anything but post whinges about Microsoft and Apple to a web server that runs SSL using a self-signed certificate and actually follows the RFCs.
The slashdot crowd is supposed to be very US centric though...we would never "whinge" about anything.
IMO there are 3 significant facts:
1) We cannot prove/disprove Global Warming in a satisfactory way, if we wait for proof then the time to react in either direction will have passed.
2) CO2 either DOES or DOES NOT affect the environment as a whole, ultimately it has become a political football.
3) We ARE treating the earth like a whore.
There is nothing we can do about the first 2 facts.
I would definitely love to live longer then 100 years, but consider what would happen if a person could live indefinitely. they'd have to have some pile of savings to support themselves, they'd have to have a pile of people in the supporting generation to support them or they'd have to continue to work as long as you were alive.
#3 sounds fine to me. Work for 30 years, take a mini-retirement for 3 years, then start a different career, repeat as often as you like. If your body and mind stay healthy there's no reason for permanent retirement.
Can't any amount of power move the ISS just at a slower rate?
Kind of. It has to boost altitude, on average, more than 200 meters per day, just to keep up. Over and above that, yes anything will do.
There is also a scheduling issue. Currently they burn chemical thrusters every month for a couple hours. That means no "microgravity environment" for less than 1% of the time. That is OK, 99% of the time is good enough for experiments, etc. Now, if the fancy new vasmir can only boost 400 meters per 24 hours of continuous operation, then just to keep up with atmospheric drag, it absolutely must run 1/2 of the time, meaning you only get that fancy microgravity environment for 1/2 of the time. Also with respect to maintenance and reliability, that means it has to be operational about half the time or better. And finally, a 1% of the time activity means direct astronaut operation/intervention is possible, but there is not the staffing to baby sit a low thrust engine literally half the time, so it has to be highly automated.

"Reboost mode is necessary because the Station's large cross-section and low altitude causes its orbit to decay due to atmospheric drag at an average rate of 0.2 km/day (0.1 n mi/day)."
any vulnerable computer on your lan makes all the rest of the computers vulnerable as well.
Let me spell it out for you:
Right now, my LAN is a switch, with two things plugged into it: My server and my laptop. If either of those are compromised, I'm hosed anyway.
If I were to plug a vulnerable machine in, it's still a switched network, which means sniffing is impossible -- they'd have to actively MITM me, somehow without my server noticing. (DNS tricks are right out, as I refer to the server by IP.)
You didn't answer my question.
I'm not asking how you would subvert the system.
I'm asking how you would profit from subverting the system.
Yes, Twitter is insecure. And?
Hehe. Actually, her old car died months ago and she put off getting a new one as long as she could. She's been bike-commuting and using public transportation, but there comes a time (namely Minnesotan Winter) and a place (namely the Twin Cities public-transport-weak suburbs) where that becomes impractical.
So she's getting a small and efficient car and will use it as little as possible.
That makes much more sense. With about 4TB of disk space between the two computers, it'd be difficult to store a trillion numbers (considering that they'd need to be more than 32 bit integers).
They might be stored as a bitmap. That would take only 10^12/8 = less than a terabyte of space. Or they might store them as successive differences, which would require only 3x10^9*8 = around 30 gigabytes. Of course, the latter would be a lot harder to work with. Depends on how you wanted to use the results, I guess.
I haven't seen anyone in this thread mention SymForm http://www.symform.com/, which may well be an ideal solution for your situation. This is a fairly new startup operation founded by former Microsoft and Amazon engineers that manages a cooperative cloud backup platform. You'll need to do some reading of the whitepapers on their website to wrap your brain around the concept, but the gist of the idea is that you configure your spare storage device (like your Drobo box) to form a node that connects to the cooperative cloud, which is comprised of free disk space on the spare storage devices (SAN, NAS, external SATA drives, etc.) of the other members of the cloud. With 5,000-10,000 other nodes sharing exabytes of free disk space, there is plenty of capacity for all the members of the cooperative, and as the cloud is distributed worldwide, there is no single point of failure to worry about. The data is fragmented in such a way that it is distributed randomly across multiple nodes (in a system they call RAID-96) so that no single node in the network contains a complete copy of your data. You pay a flat monthly fee to join the cloud, and your data is encrypted by your node and backed up incrementally over your network connection. It may take a while to get your first full backup transmitted, but after that, the bandwidth is used only for deltas. It's kind of a brilliant idea that blew me away the first time I heard about it.
Many people are unenthusiastic about their work.
