It doesn't effect radio communications. It does very nasty things to electronics though. Mostly because it can provide energy directly to the inside of, say, a transistor or the inside of a dram cell causing things to malfunction. It can al

As far as I can recall, most data cables arn't shielded. Audio cables usually are, however, to stop hum/etc. when travelling over long distances. To be more specific, if you have wire it will act like an antenna. It's usually a fairly poor

How is your site structured? 1) You want to move static data off your system onto another site like s3. 2) You want to do whatever you can async. ie. if somebody shares data, you don't have to make it available immediately. Just place it in

because DNSSEC isn't required. As an example, if i mitm your dhcp request, i insert myself in as your dns server and gateway and i just say that DNSSEC isn't enabled for this domain. You have to trust me, and I can give you a MITM'd page. S

SSL locks identity with encryption to prevent MITM attacks.

Yes and no. Yes, on any sort of small network, you can be instantly MITM'd with basically no protection. No, in that on any sort of large scale traffic it becomes impractical to filter, ie. with modest hardware you can trawl through http at

eh, there exist plenty of things that are nice and shiny. I can take pidgin and OTR and with about three minutes worth of "You should click here", have it set up easily enough that even a complete non techy can use it. The problem is 1) It

Basically if you see a certificate on the interwebs, it goes through and says: "This particular website is X". And it can back this up with all sorts of fancy math. The problem then, is how do you know that the particular certificate is cor

Say you were to use a pebble bed reactor (Modern aircraft, modern reactor). The reactor is designed in such a way that in case of coolant failure/containment failure/etc. the pebbles equilibrate at a stable containable temperature, and as s

What potentially devastating consequences would there be if an oil rig had been hit by an earthquake, tsunami and explosion? Also consider the size of an oil rig(s) that would need to provide the same amount of energy. Similarly, what would

The question is what exactly you expected of it. You've taken one of the oldest and least intrinsically safe designs since chernobyl (at least compared to anything recent like a nice pebble bed/molten salt reactor), hit it with an earthquak

Solar thermal is in fact a very interesting technology. I've looked into the pilot plants over in the desert in california and it seems like a real step forward. Its also interesting that they seem to solve parts of the "baseload power" pro

The power for a particular grid generally has two components, that which is always on and that which fluctuates through the day. To give you an example, an aluminum smelter will always use a fixed (and very large) quantity of electricity,

What is nicer is that your body naturally replaces most of its water every few days, so you arn't stuck like you would be with say sr-90 trying very hard to embed itself in your bones :(

The problem with solar is that they require large amounts of resources to produce but also that they also produce the wrong type of power. To give you an example, think of a way to run a large aluminium smelter overnight using just solar ce

You'd be surprised at how quickly people can get things done if their lives are on the line. We have more then enough thorium in the world to deal with the world's power demands (It's about as common as lead), we have much safer reactor des

Cancelled nuclear plants probably have more to do with public relations then actual danger. As an example, 4,000 people died in 2007 collecting coal for power plants, oil pipelines have a habit of https://secure.wikimedia.org/wikipedia/en/

IANANS, however from what I understand the problem is this: -> The reactor is a BWR type, hence even though it is scrammed it is still generating some amount of power from fission products. -> The ECCS failed, meaning that the core
