Comment Re:weight of elevator is pulling up, not pushing d (Score 2) 374

If cars on the lower part of the ribbon are pulling it down, this means that slightly less ribbon will be above GEO point, leading to less ribbon available for counterbalancing the lower part. Which means an unstable equilibrium.

So, in order to prevent the whole thing from crashing down, there has to be a safety margin of extra ribbon above GEO, meaning some extra tension in the wire, even at ground level. That barge can't be too light-weight, or else it'll turn into a space-barge...

Think about a foundation strong enough to withstand the pressures of a 100-200 mile high tower pressing down.

Connected to a platform in space, the mass of the platform is to spin with the Earth's rotation. Centrifugal force is actually pulling on the elevator 'cable'.

Actually, pulling up is much worse than pressing down... The cable would just rip the foundation out from the bedrock. So you'd need to drill really deep to suitably anchor this beast.

Years of using MS product GUI's have conditioned people to do a quick click through and accept everything so the default ends up trusting some proxy box as if it is the bank.

If people behave in such a way, they'd be vulnerable anywhere (cybercafé, airport, hotel or even at home (thanks to the many router vulnerabilities)), not just at their place of work. Microsoft, and Microsoft-induced behavior carry security risks. Deal with it.

However, what sets the workplace situation apart from the other scenarios is that if done properly, the employee would see no warning. Because the IT department included the employer's certificate into the list of roots trusted by the browser.

With all the setups of this type I have heard of there is no opt out.

Worse than, the "SSL accelerator" box would now be responsible to check the certificate of the server, in order to be sure that there isn't a second man in the middle further down the road. But the thing is, how would it react if it encountered a bad certificate:

- if it rejects the connection, suddenly lots of low sensitivity sites which just have expired certificates, or which rely on the user to manually verifiy the fingerprint become inaccessible,
- if on the other hand it accepts (or doesn't check in the first place), we have the security issue outlined above.

You mean if one were to send an email from Munich to Paris, it'd cross the Atlantic and come back?
NSA aside, that's a pretty sucky setup.

Many Europeans have accounts at gmail or hotmail. In this case, the email does indeed cross the Atlantic and back.

O, and "creative" routing, as you outlined, does happen often enough too, unfortunately...

9/11 wasn't the breakpoint of the economy

But a large contributing factor: ...the outbreak of a great fire in the heart of the city of Boston on November 9th was a disaster. Firemen were reduced to moving all of the necessary firefighting equipment by hand, and the size of the fire in this particular incident did not allow for such slow movement to be effective. The firefighting sans horse power was so ineffective that the fire raged on to become one of the worst disasters in the history of the city. Reports indicate that the blaze killed 13 people, destroyed 776 buildings, and caused $75 million in damages – the current equivalent of roughly $3.5 billion.
