+ - Yes, Virginia, Black Holes Exist!

Submitted by StartsWithABang
StartsWithABang (3485481) writes ""And so what these three papers, in tandem, have done, is demonstrate that there is no firewall and that the resolution to the firewall paradox is that the first assumption, that Hawking radiation is in a pure state, is the one that’s flawed.

You won’t read about this in the popular write-ups because it doesn’t have a catchy headline, it’s complex, and it’s not work by someone that’s already very famous for other work. But it’s right. Hawking radiation is not in a pure state, and without that pure state, there’s no firewall, and no paradox.

There is still an incredible amount to learn and understand about black holes, event horizons, and the behavior of quantum systems in strongly curved spacetime, to be sure, and there’s lots of very interesting research ahead. These findings arguably raise more questions than they answer, although at least we know that black holes won’t fry you when you fall in; it will still be death by spaghettification, not by incineration!"

Listen to what the best science has to say, not just to the most prominent scientist who says things."

Invalid argument. The coffee is chemically active so the flavor CHANGES after a short amount of time. If you have not had coffee just roasted and tried it over a period of days you would not know the difference. The easiest way to describe is that it gets mellower and less sweet. As to weather it really makes a difference that is subjective. If trying to brew the PERFECT cup of coffee however then it definitely makes a difference. Coffee being discovered in Ethiopia tends to give enormous credibility to the practices and methodology of Ethiopians regarding coffee. The initial period of 12-24 hours for degassing, standard practice among europeans is ignored since all the coffee is used right away. This mostly applies to bubbles that foam up during brewing but coffee that has not degassed has a wilder flavor also. In practice at home I usually use it within 2-4 days but after 5-7 days it is not the same. as before of directly after the 12-24 hour period; first getting mellower and then towards bitter.

What are your thoughts regarding pre roasted coffee versus roasting at home? (I personally roast at home with a popcorn popper and find that it produces better results at a lower price. The founding belief being that coffee being a chemically active substance after it is roasted makes it theoretically impossible to store roasted coffee and retain the original flavor since it can't be stored at absolute zero.)

Maybe it was an illustrative device but you would not need to use lead. The standard practice is to use a Faraday bag or case which could be made of lots of different materials including lead as long as it is electrically connected to the closure. Lead is used for radiation shielding but for electro magnetic shielding a Faraday bag or cage is used...

Comment: Net Metering (Score 1) 207

My comment is regarding net metering in general not specifically as it applies to solar. This is a bigger issue; it's not just with solar that net metering comes into play. I know someone who has a factory and a hydroelectric plant. He sells the energy to the electric company and buys it back at a very small markup. "If you make extra power the electric company is bound by law to buy it." I see no reason to change this; its simply common sense and it applies to more than just solar. These rules have been around for longer than solar was a thing for private citizens and everyone wins. Use of smart meters is especially helpful in these scenarios since the grid is aware when extra power is being generated as well as when it's needed.

+ - The Debt Crisis From the Founders' Perspective

Submitted by Cow007
Cow007 (735705) writes ""The U.S. Debt Crisis from the Founders Perspective is republished with permission of Stratfor."
A worthwhile read for a little perspective.
"...I think the founders would have questioned the prudence of our current debt. They would ask if it were necessary to incur, and how and whether it would be paid back. They would also question whether economic growth driven by debt actually strengthens the nation. In any case, I think there is little doubt they would be appalled by our debt levels, not necessarily because of what it might do to the economy, but because of what it does to the national character. However, because they were moderate men they would not demand an immediate solution. Nor would they ask for a solution that undermines national power.

As for federally mandated health care, I think they would be wary of entrusting such an important service to an entity they feared viscerally. But they wouldn't have been fanatical in their resistance to it. As much as federally mandated health care would frighten them, I believe fanaticism would have frightened them even more.

+ - Do the NSA and others really NEED to do what they have been doing?

Submitted by Cow007
Cow007 (735705) writes "Here's the question nobody seems to be talking about in earnest: do they really NEED to do this. All of the powers been developed for gathering information are they able to accomplish their stated goal without it. isn't it really a matter of analyzing intelligence they have that is the issue? I tend to lean in some ways towards a yes answer for that question. However intelligence analysis is not something to be under estimated. When looking back over the events of 9/11 it became clear that the government had the information necessary to be able to prevent the attack or know about it in advance.

Does the cost-benefit ratio of this surveillance to infringement on freedom truly pan out when were talking about terrorism? The founding fathers would probably say no, however in situations where there's a possibility of terrorists acquiring acquiring CBRN weapons this is a difficult question.

In calculating this cost-benefit ratio one would have to take into account the possibility of this actually happening. However the most concerning situation would one where terrorists used biological weapons. Such attacks would be much more cost-effective than building a crude nuclear device or using chemical weapons since it's fissile materials are hard to come by and prohibitively expensive as are radiological materials suitable for building a dirty bomb. It is also notable that chemical weapons are difficult to disperse effectively and require a larger amount of material. By far the smallest amount material needed for an attack would be biological in nature.

If someone were to distribute a lethal, transmittable and weaponized virus we would be talking about fucking Moonraker level damage to human life.

I don't know if you remember but it was talked about in the media that the NSA was going to do "a mop up operation" after 9/11. The goal of this procedure was to go back through their databases and whatever stored information they had in the files to extract information such as phone calls regarding this event. They were in fact able to extract phone calls probably talking about the operation on 9/11. For example a phone call using code words such as the wedding is a go etc. I developed the opinion that it would have been possible for the intelligence community, properly coordinated could have analyzed the intelligence they already and been able to prevent the attacks or at least have some information about them being a possibility.

A big problem with having more intelligence means that you have more intelligence to sort through. This is reflected by the NSA's efforts to be able to analyze large amounts of information. Nevertheless this is a trade-off.

What do you think? Did the NSA and other government agencies really need all the tools that they been developing to be a will to adequately execute their mission?

In regards to encryption it is definitely a system of very low cost method to be a will to make it very difficult for others to be able to decipher information. Should the NSA undermine encryption standards be provided with keys for them or two at the old-fashioned way- hard way?

I have been thinking for a long time that for the NSA to properly do their job they would have to be able to decrypt communications. So much so in fact that the NSA would seem like a nearly irrelevant body without this capability. I think that they must be using quantum computers or heavily developing them to be able to do this. Evidence of seems to suggest that they have not fully achieved this capability as of yet as evidenced by the continued need to undermine encryption standards or circumvent them.

The problem with using quantum computers to pick up messages within data that is theoretically impossible to distinguish from random data and streams of random data due to encryption circuits that are continuously loaded.

I joke that if one is using quantum computers to find messages in data that may contain random data or actual encryption then decrypt they will always find exactly the messages they are looking for :P"
