Verification of identity is self evident if only the source and destination can decode a message. A man in the middle attack gets garbage if they don't have the key.

The only way a man in the middle attack works in this system is if you're passing keys back and forth and the man in the middle intercepts the key.

There are a variety of means of avoiding that besides using a trusted third party. After all, how do you know that the trusted third party isn't compromised?

They are themselves verified by having some key or other but whatever that is tends to be pretty easy to find out if you're determined. Which means it isn't a credible defense against a serious attacker. Against a casual attacker... sure.

How then does one avoid man in the middle attacks? Do not transmit handshake keys.

For example, let us say I am logging into my bank. My bank might ask me to type in some combination of account number, birth date, street address, phone number, into a box that generates a key. The bank knows what key will be generated because the algorithm is not secret. But the information the bank asked you to input as the key is something a man in the middle system shouldn't know. By typing that in or possibly using some sort of complicated captcha, you can generate a handshake key that an automated system without access to the bank's database won't be able to generate.

That key can then be used to exchange stronger encryption keys.

Beyond this, we should think more deeply about saving/storing BIG complicated encryption keys on devices used to do certain things. Say your tablet or pc or whatever. Why not store a 2 megabyte key? Beats the hell out of a 512 bit key. Possibly overkill, but a key of that size is going to be proportionally harder to crack because it won't repeat as often. The bigger the key the harder to crack.

And a key that equals the number of bits transmitted is literally impossible to crack... by anything... ever.

and then writing science fiction. I don't even disbelieve what they say, it's just being said without any sort of consideration of either the cost or the benefit. Hey, I can write novels about mining the asteroid belt, extracting He3 from moon rock for fusion fuel, building orbital space cities, and settling the moon too, except that Heinlein and many others already did most of this, and all of their novels presuppose some method of getting around that doesn't cost a gazillion dollars and thousands of megajoules per kilogram moved. With that kind of cost, why hire crack smokers to write SF? There is a lot of work a lot closer to home that is ALREADY too expensive for the benefit.

In the meantime, time to write another SF novel: "The Floating Cities of Venus". Yeah, got a nice ring to it.

Comment: Gender specific courses are wrong... (Score 1) 180

... unless we segrigate the genders again which I think might be reasonable from grade school to highschool.

The hormones and learning patterns are different enough that it is problematic to have a one size fits all education program for both.

The boys operate under different rules especially at that age. Separate them out and it could improve all sorts of things. I think most of the experiments with sexually segregated education have shown dramatically improved educational performance. So... no reason not to do it really.

All they're going to be able to do is attack US DNS servers. But I can point my router at any DNS server in the world.

What is more, the entire DNS system can be bypassed with sufficiently detailed host files.

It sounds absurd but consider how cheap storage is these days? I could maintain a pretty comprehensive private DNS list on my own systems without burning that much HD space. What are we talking about here? Maybe a couple gigabytes? Map that into a fast database and you could literally point your computer to look up DNS entries locally.

Or if you prefer you could just have it look up blocked sites locally. Either way, the DNS pitch is counter productive. They're just going to encourage pirates to learn how to play with DNS.

I'd love to see Obama do that... the shock of all the republicans suddenly giving him everything he wants would be pretty priceless.

Republicans aren't opposing obama because he is obama... they are opposing him because they do not like his policies.

Suggesting otherwise ignores that republican policies on these matters haven't changed remarkably in decades which is long before Obama was even alive much less in politics.

I'm afraid that is just the cognitive dissonce talking.

Obama likes to say that people only disagree with him because he's black or something equally offensive. But if anyone else were in his position doing what he's doing then the same political factions would be opposing him.

Republicans for example has been opposing moves like Obamacare for well over 60 years. Yet Obama suggests that republicans are only taking this position out of racism. It is intellectually unsupportable.

The same is true of the FCC actions.

Who said anything about redoing the cabling every time you change providers you complete fucking retard? That is a CFR by the way. :D

The only cabling that would need to be redone would be at your house where in one cable was unplugged and another was plugged in instead. OH NOES! It might take all of 10 minutes! RUN AND HIDE!!! THE HUMANITY!!! AAAAHHHH!!!

Seriously though... what the fuck do you think you're talking about. If I have a bundle of cables going through a street conduit or over on a pole... and I need to switch from one cable to another... why are you presuming any of this would be hard, time consuming, or messy?

I'll give a simple example of an office building. There is a utility room in most office buildings where most of these things are routed. Often they'll have more then one but lets just go with a simple example of one utility room. In that room, you have communications and power lines coming into the room and then those have to be routed to specific rooms or even jacks. All of this is labeled on the panel. Changing from one provider to another would require moving some of these wires around. Which is precisely what they do already when you add a service or change a service. Nothing here is really changing from a wiring perspective.

Going through the streets, you have a similar situation. ISPs already play with the cable as it is... they'll continue to do that. It doesn't need to be relaid every time you change service. I never implied that, never suggested that, and that is not my argument.

Taking that many pictures of "life" events, unless you're a photographer professionally, is completely void of meaning. The problem is, if your too busy taking pictures, you are NOT participating. Personally, I take a few pictures, to remind me, and then participate, which provides me with way more satisfaction than if I were sitting on the sidelines snapping hundreds of photos.

As to regulation being required for competition... yes, but the regulation required is that companies do not literally commit acts of violence, contracts are honored, and advertizing is reasonably faithful to the actual product.

Which is something we have for every company already.

The issue with ISPs is not lack of regulation but too much regulation. Again, at the local level. It is almost impossible to lay last mile cable.

That is the issue.

Make that easy from a regulatory stand point and this issue will go away.

You cannot justify regulation because we have too much regulation.

That just creates a feedback loop of stupidity.

Actually, you're missing the point.

What the scientists are saying is that the droughts they're seeing do not appear to be unusual. They appear to be totally normal, predictable, and unmodified weather patterns.

If you want to blame these droughts on AGW then you might as well blame summer on AGW and winter on global cooling.

You cannot blame such weather patterns on AGW while retaining credibility. Choose.

Do you want to blame them on that or retain credibility?

The major benefits to the 1 percent at the expense of everyone else is largely due to no one but the 1 percent having capital investment in the system.

Going forward, it should be if anything easier for common people to have capital investment in the system because the system is going to decentralize.

Think of the advantage of having massive cheap automation. Do I need to have a big factory if I can pack my workers in boxes? No. I can have micro factories that are closer to consumers or resources because my manufacturing doesn't need to be near large concentrations of labor.

And if my factories are smaller then they become closer to what small and medium sized businesses could afford.

Imagine fully automated car making robots. Big 3d printers with assembly capability. Now imagine that because these printers can print most of their own parts that all this crap is relatively cheap.

Your job of the future might be owning your own car company that makes 10 or 20 cars a year.

Just a wild example of something that might happen. I can't see the future any more clearly then the fool that wrote the article.

The point is that people are assuming the industrial models we have today will remain the same. Why would they?

Think about what massive automation will do to all these industries? Suddenly a big factory can base itself in an isolated part of the country because it only needs a tiny fraction of the labor. And if it can, then it should because the land costs etc are lower out there. And if the labor really ceases to be an issue then the economies of scale change. Most economies are scale are based on labor density. If labor isn't relevant then you don't need to build densely and really since density has problems you shouldn't be dense.
