One of the pgp guys proposed a voice chat thing. Where you both veryify some shared secrete verbally as the first thing you do. Probably as good as its going to get really. However general encryption is still no good without MITM protection when the threat model is government eaves dropping.
That provides end to end and is vulnerable to MITM attacks which is really part of this threat model (Your isp is untrusted). You need authentication typically long before you need encryption, in fact without authentication your wasting your time under this threat model. Then there is all the data you *can't* encrypt. Like *who* you email or talk to. Where that packet is going.
I am sure there is at least one website somewhere that probably blames Sep 11 on NSA remotely hacking and flying those aircraft into the towers. With chem trails!
Google it. There are some. Note that coil guns have limited velocity and power. Rails are easier to get deadly with a power source that can handle the current. Linear motors are between both. Also i would not want you firing this thing at me. You could take out an eye!
The controversy is in fact much simpler. "Gangsters can make their own guns!" is scary. Replace Gangster with whatever your moms current boogie man is and that is the controversy.
Never mind the fact that these people have all the guns they want anyway...
not up and running by default with zero configuration on programs first install.
Encryption programs that do that, won't be worth there cpu cycles. Where are the keys coming from? Who do *you* trust. What about expired keys and other key management things?
Proper secure point to point encryption over the internet, is not zero configuration.
The threat model in this case is the government. So MITM attacks are very likely a real threat. People will expect it to work on their phone, tablet and PCs around the house without any more annoying configuration. It just does not work. Look at the state of SSL.
This is incorrect. Its easy to prove in the case of a one time pad. If you don't have the key, then all possible messages are valid plain texts, there is no way N=NP can help you tell which one is correct. Symmetric key systems do not require N!=NP, they rely on the fact that there is a "secret function". Without knowledge of that function (ie the key), you cannot invert that function.
Well "worth" is not the same as "has assets that could be liquidated to that value". Its often mostly over inflated because they have a large chuck of shares in a company that also has large "market cap" or whatever its called.
I never asserted that it was harmless. But the amounts here, given that from a nuclear fission plant, its typically quite dilute, and that it will almost never be alone without other contaminants, its not clear at all there is something to worry about or not. All sea water is Triated to a parts per trillion level because of nuclear testing. That doesn't make it unsafe.
And note the lots of "may.." and "could.." in these studies. Also note these are really old studies. I am sure i have read more recent ones, including more recent work on threshold models that involved nuclear plant workers.
Its also good in that its low energy beta, and that it has a fairly short half life (both nuclear and biological) and will dilute with natural water to below background levels fairly fast.
The bad is I don't see how water with tritium in it won't also have other stuff in it....
In this case the exposure model is fairly simple (assuming it was only tritium). Since tritium is a very weak beta emitter, it only matters when ingested and has a short biological half life once you start drinking non contaminated water. It does not accumulate in any particular organ. If its already dilute enough (possible technically), then it would pose very little risk compared to background.
For radiation release events like this, it's simply the overall amount released for the whole event. You don't need per volume or weight.
Yes you do. If that leak was a cubic meter of water or a cubic kilometer has a massive impact on the relevance and effects of the leak. Without that information you simply cannot gauge anything relevant from a risk point of view.
You seriously thing that using terms that convey no more meaning will help with understanding? Really? You don't try explaining things to the laymen very often do you.
Also 99.99% of people have turned off their logical part of the brain at the first mention of the work nuclear anyway.
Now for some better considerations. There is no indication of how dilute this is, and its likely quite dilute. Its tritium which is very low energy beta emitter and only poses a risk when ingested. In fact it could well be so dilute that drinking nothing but this water would not increase your does significantly from background levels. I doubt this is the case... But the fact remains, that the relevant facts are missing. At least from the summary.
It is easy to avoid these patents. Just don't do the most obvious thing when "compressing" a point on the curve. Because that is what the patents cover. There are some hardware implementation ones around. But for general computation they don't matter. And of course if your not in the US then you don't need to care about software patents anyway.
Shor's method (the quantum one) solves the discrete log problem. Solving the discrete log problem can also be used for factorization. The papers in question solve the DL problem and hence can be used for factorization as well.
Public key encryption requires trap door functions. We can't even prove they exist. Most people believe they exist. If you can prove they do exist then you also prove that NP!=P. But proving NP!=P does not imply the existence of trap door functions.
So what this means is we try and find trap door functions. Things that appear to be easy if you have some piece of information, but really hard if you don't. There have been such functions suggested in the past that proved to be easy in both directions in the end (knapsack problems for example).
TL;DR Its much harder to find practical public key methods than symmetrical key ones.
What i don't get is what really breaks with a second error or jump. I often just do the ntpdate thing and my clocks are shifted a lot more than a second. As long as i am not compiling, i havn't had any issues.
I understand some secure protocols need accurate global and difficult to forge time. But outside that? I mean so what if the time on a wall post is out by a second?
I have a few simple goals for the Zombie apocalypse. Since a real apocalypse they way people think of it as is about as realistic as zombies. It has a particular congruence.
Goal 1. If i become a zombie, I wish to be patient zero. The Alpha Zombie if you will.
Goal 2. If not i intend to be immune. No not that loser Legend but a real one.
Turns out exposing myself to everything infectious is the way to go for both 1 and 2. Like a poor mans vaccination. And gives me a reason to call a lot of friends out on ridiculous hygiene rules. Things like if a cooked chicken gets warm for like 10 secs and you eat it, you die. A cold breeze with make you sick (gota love the german "zugluft") etc. I am a scientist and you wouldn't believe the unscientific things they all believe. So i get to do all that in the name of the Zombie apocalypse. Seriously if we all died the second someone coughed, or didn't cook chicken to a dry overcooked chewy, we wouldn't be here
On a more serious note. If such a topic can ever be serious. Most of the "provisions" and stuff people think is preparation wouldn't work anyway if there was a genuine Apocalypse. Goretex or anything else for that matter never lasts forever. If people think its back to the stone age. They better learn how to actually live in the stone age. I for one would miss toilet paper.
The scary thing is some people really do think there is an impending apocalypse. There is always a group that does. Its a sure way to get followers, preach that the end is nigh. Even the AGW crowed are doing it now (the "do the math guy" for example). What is really funny, is even though people believe it, they just go about things the same way as if they didn't.
The fact is with current levels of industrialization and technology. Even a big asteroid is not going to wipe out humans. Nuclear war won't wipe us even if we tried. And the "slow apocalypse of climate change" will be a slow shift compared to the technology changes of that time frame. We have intelligence and it is the pinnacle of adaptability.
We don't need to recreate all the muscles, fat, blood vessels and their precise relation to replicate a taste. Our sense of taste is just not accurate enough to distinguish between good enough and perfect. In fact i don't think cultured meat like this will ever be popular. Because by the time we can do that affordably, we will be able to make artificial meats from "raw" products (ie proteins etc.) Say extrude a food muscle, that when cooked can't be distinguished from the genuine article by most people.

Rail guns use magnetic fields like coil guns. But in a very different way. In particular the projectile itself is part of the circuit.
