Not exactly. The eavesdropping is actually detected during the key exchange (the "quantum" part), so if eavesdropping is detected, the message is never sent in the first place. If the key is exchanged without any eavesdropping, the message is encrypted with a one-time pad and sent through more traditional channels.
The details of the key exchange part is what is most interesting.. it can't be a fully quantum process since there is no possibility of binding identity to the quantum channel.
Verification of identity requires classical communication and standard encryption technology to verify an OTP peer.
An attacker pretending to be copious noise can still probe your initial key. If the key is later compromised an attacker could leverage the verifier during key exchange to obtain clues about subsequent OTP data transmitted via quantum channel.
Remember to bring a copy of the human genome with you and Mars will be great fun. You'll meet aliens, get a history lesson on a display that makes imax look like betamax and take off for god knows where on a cool spaceship.

"Representatives Dan Burton (R-Ind.) and Dennis Kucinich (D-Oh.) made speeches connecting vaccines to autism"
Having spent about three hours with the hearing blazing in the background the summary and article are completely unfair and misleading.
Even the main villians Kucinich spent most of his time talking about environmental factors citing well known studies and UN data on human caused mercury pollution from coal plants.
The issue of vaccination was hardly discussed at all other than a congressmen begging for any remaining thermerisol still in use to also be canned universally...
"Although there were actual medical researchers there as witnesses, they were mostly berated by the Congressmen on the panel."
I love kuccinich's opening salvo. He references a thermirisol shield rider added by unknown person to the homeland security bill of 2002.
Trust and legitimacy is absolutely critical here peeps. When parents see government shennanigans and corrupt behavior it is hard to stand around and act surprised when they decide to distrust government recommendations.
I hate skeptics who often use the same tactics and logical fallacies as the conspiracy nuts..only they don't end up looking like crackpots only because they happen to be on the right/safe side of the argument.
In my view the biggest problem with these debates is hubris. Parents think their experience means shit. Doctors the same. Both are wrong.
The only people qualified to draw any conclusions are the statisticians.
Statisticians can't well do their jobs effectivly when bias and lack of conformity is baked into available feedback channels.
There are still doctors who see children after vaccination with high feaver or other problems and don't file the damn report because *they* don't see a link... an attitude made of the same misrecognition of the limits of ones own knowledge as any Alex Jones vaccination tirade.
There needs to be mandatory uniform reporting with appropriate education/guidelines to all doctors on vaccination reactions so everyone has quality data on which to draw informed decisions.
At least the government is trying but they should NOT have to be in a position of begging and settling for incomplete data.
"VAERS is a passive reporting system, meaning that reports about adverse events are not automatically collected, but require a report to be filed to VAERS. VAERS reports can be submitted voluntarily by anyone, including healthcare providers, patients, or family members. Reports vary in quality and completeness. They often lack details and sometimes can have information that contains errors.
"Underreporting" is one of the main limitations of passive surveillance systems, including VAERS. The term, underreporting refers to the fact that VAERS receives reports for only a small fraction of actual adverse events. The degree of underreporting varies widely. As an example, a great many of the millions of vaccinations administered each year by injection cause soreness, but relatively few of these episodes lead to a VAERS report. Physicians and patients understand that minor side effects of vaccinations often include this kind of discomfort, as well as low fevers. On the other hand, more serious and unexpected medical events are probably more likely to be reported than minor ones, especially when they occur soon after vaccination, even if they may be coincidental and related to other causes."
Geeks are to blame for most of the loss of human rights on the net.
When I started the Internet had a lot more people who cared about tinkering, improving and contributed to the network than people seeking to profit and leech from it.
It was a few years later that the spam started flooding in.
The rise of centralized systems fueled by the masses who just want to pay to be users without contributing back to the network is a bigger problem to our freedom than any government spying. If you really want to change things you have to find ways to get more people to be involved with the network again...
Running your own servers has to be cool again.... not "to the cloud" cry of marketeers who seek money and control.
The barrier as I see it is not really about technology it is more about getting more people interested and involved with the network.
Ease of use as you point out is a critical factor but I recall lots of ordinary people learning html and setting up home pages back in the day...
Wikipedia codes are hardly user friendly yet lots of ordinary people are still motivated to learn unecessary shit in order to improve and contribute information they care about.
Technology and making things easier is critical but I believe motivation is more important.
Unless we can find a way to get more people to care about the network I don't see uber technical solutions alone being sufficient to cross the finish line.
To make Win8 usable, you just have to install it. It is quite usable as is. Maybe not efficient, and probably not agreeing with the preferences of many people, but that is not the same as being unusable.
People have their own standards regarding what constitutes "usable". Those with a low threshold for nonsense or high standsrds could rightfully conclude windows 8 is unusable in its current form.
The question of usability is value judgement you do NOT get to make for others.
I have no problem with touch displays and people purchasing them. Everyone should be able to make their own decisions and purchase whatever works for them.
I do however have a big problem with metro and everything it stands for.
The only way to obtain metro apps is thru vendor curated environment with full editorial control over what is or is not available. This is unacceptable. Enabling such aggregations of power will ultimatly lead to abuse (See shit apple is doing to shut down apps which compete with their interests or do not meet their decency standards) Such structures are ultimatly dangerous to a free society if vendors and content ultimatly get their way and eventually succeed in locking down the general purpose computer.
Severe limitations regarding display of multiple metro apps on screen makes metro unusable to replace "windows" on large displays.
Fads and memes of the day are not "the future" as Hollister asserts... no matter how much coolaid has been consumed.
Okay, here's your article about why Linux failed on the desktop. Explanation is simple. Microsoft has had a powerful entrenched monopoly on the desktop.
Yep it was all MS not playing fair while their competition was GIVING THEIR PRODUCT AWAY.
It does not matter what anyone says the simple truth is life aint fair. You succeed or fail with what you have not with what is "fair". There is no "level" playing field. Your onesided fairytail about how evil MS is responsible for linux failure is like blaiming the ref for your teams loss. You can either learn and do better or be like my whiney little sister.
In areas where Microsoft does not have an entrenched monopoly, it does not know how to compete. Competition is not even in their DNA.
They are competing with Oracle... and we all know brother Larry is a saint who plays fair.
They are competing with webkit and firefox.
They are competing with google on search and "free" messaging.
They are competing on smartphones.
Furthermore, Microsoft has no vision. None. Zero. Every product from Microsoft has been copied from someone else, or acquired from someone else.
Welcome to the real world. It is a universal truth in business big fish eat the little fish.. and you know something most little fish are ecstatic to be aquired by big fish.
Slashdotters say touch screens on laptops and desktops are insane,
I think this is pretty much a universal consensus. If there are any questions sit in front of a desktop and hold your arm out straight in front of you for an hour then come back here and let us all know how much you enjoyed the experience.
You may not understand the change adverse meme, but I don't understand the "I'm an expert, how can I be expected to use simplified things?" meme.
Statements which are not falsifiable are not worth understanding. They convey no useful information of any kind.
The claim anyone who would want to see more than two apps on screen at once or has a need to move and change the size of windows are somehow elite experts which can be ignored seems implausible and condescending.
Metro is appealing to the consumers, that's what it's doing there.
I sure hope its appealing to someone. I have yet to find anyone in real life who agrees.
I recall back in the day when Microsoft replaced Windows Executive with Program Manager and people lost their minds. Then they replaced Program Manager with the Start Menu and people lost their minds. Now they are replacing the Start Menu with live tiles or whatever they are called, and people are losing their minds. Again. If you don't like your UI ever changing, buy a Mac. The MacOS UI peaked in like '86 and hasn't changed since. iOS peaked in '08 and hasn't changed since. Microsoft is trying out something new - again - and chances are in five or six years they'll try something else new and everyone will whine about the loss of live tiles.
To demonstrate how ridiculous statements which cannot be falisfied are let me offer the following counter-example:
If Microsoft labled MS-DOS Windows 9 there will be people who will loose their minds.
I never understood what the point is when people beat this drum and invoke the age old change adverse meme?
If you are not willing to discuss a change on the merits then what information is being conveyed when you make statements which cannot be falsified?
Personally I don't like metro because it breaks a fundemental core component of every GUI I've used in the past two decades. The simple ability to arrange and size program windows to suite my needs. What am I supposed to do with my huge monitor when I can only have two metro apps showing on screen at once? I don't understand... People can counter with use the desktop all day but then what is metro doing there? How is it helping me? What happens when I have to run a metro app?
Why is Microsoft a failure in the phone and tablet business?
You tell me, did Nokia just sell >11 million WP8 phones in a few days or was it my imagination?
It should be obvious -- people don't want what they have come to expect from Microsoft on their phones... rebooting, slowness, crashiness and vulnerability.
I use windows systems all the time and they never crash or spontaneously reboot...its been soo many years.. We had three racks of windows servers for 10+ years just run for all that time without EVER crashing even once. All modern general purpose operating systems are extraordinarily stable. The secret is paying the premium for ECC, burning in storage and running memtest for a day before you start to use a system. Most stability issues are hardware and or environment related.
If Microsoft EVER wanted to participate in the phone/tablet market, they first need to address the problems people have with their current OS and Office products.
Whats wrong with office?... or dare I ask.. what is better than office?
In contrast, Microsoft has done well in gaming. Extremely well.
I'm not so sure this is entirely accurate... has the xbox ever been profitable? Ever? Last time I checked they are several BILLION in the hole on gaming.
But don't turn Windows into a phone or a tablet. We don't want it.
I hope it does not take MS much longer to figure this out.
I'm a big Postgres fan and no Softie, but you sir preach ignorance as strength
Managing concurrency is the single biggest impediment to scaling we and most outfits face.
If you can't figure out how to perform the same function using an optimistic concurrency model I don't want you anywhere near our systems. If you think that makes me ignorant then so be it.
There is simply is no correct answer which involves laying a read lock. Oracle rightfully does not support ANY of these concepts or isolation modes. This only exists in sql server because certain children with trivial problems did not want to be bothered to expend the time and effort to design scalable systems. We can't afford it.
Tunneling brokers are a security fail. Do you really want all your traffic going through a single, unaccountable third party that makes no guarantees? Particularly one that is probably not
I agree with your general message people are better off waiting till they have native connectivity but for those of us who want to dink around or have a reason to use IPv6 now I don't see any problem with a tunnel broker.
I trust hurricane electric as much as I trust any other anonymous router/tier x ISP along the network path. The Internet is inherently insecure regardless of who your ISP is... the way I see it your better off assuming every router on the Internet hates you and therefore use end to end precautions to protect integrity and privacy of your data.
in your country and thus is not a legally accountable? And is probably deep packet inspecting to cover their costs?
In my case they are not only in my country they actually have a tunnel router at an IXP most data thru my ISP transits anyway... latency between IPv4 and IPv6 is virtually the same. Been working flawlessly so far.
Hopefully comcast gives me my native prefix soon and the tunnels can go away.
Doesn't switching to IPV6 virutually guarantee the **AA spies would be able to tell exactly which computer was used to download supposed infringing files?
This is what privacy addresses are for. They are enabled by default on windows and can be enabled manually on the MAC. Basically computers get a random address that keeps changing over time.
I must say however using torrents to download illegal crap is pretty stupid nowadays you should assume 100% coverage from both LEA and "*AA spies".
Transfer files directly between you and your friends. This is not only safer for you but by denying feedback channel to "the man" it helps protect the Internet in your country against excuses for opressive legislation by officials who are in bed with big media interests.
Cable companies have it somewhat easy. DOCSIS 3 requires hardware to support IPv6.
From what I understand cable companies are sitting on their thumbs waiting for multiple vendors including Cisco to fix broken code at the CMTS so operators can actually deploy IPv6 to their customers.
Interesting comment. MS SQL Server Locking is painful compared to Postgres when you have a huge number of transactions going on (per-page rather than per-row in general).
What are you talking about? Can you be a little more specific?
MS SQL Server is fast, but this is for a reason, it cuts corners in some areas.
What corners?
but for most uses Postgresql is actually superior
Why?
Just saying I think x is better than y without providing a cogent explanation is not helpful.
With SQL Server, you set your transaction isolation level that you care about and then you begin a transaction - SQL Server will guarentee consistency in that transaction even if you're just doing multiple selects. And, SQL Server will not let you do a 'select for update'.
For example:
SET TRANSACTION ISOLATION LEVEL SERIALIZABLE; BEGIN TRANSACTION; SELECT TOP 100 * FROM MyTable
Come to think of it... this would really make a great interview question.
Anyone who answers "are you fucking insane?" or "what is isolation level serializable?" is hired.
Anyone who talks about all the great useful things you can do with these isolation levels gets shown the door.

I agree with one or more of the ACs. We should prioritize the smallest packets over the largest. Why? Because realtime is in small packets
This is too simple/naive and mucks up congestion avoidance.
So small VoIP packets would get priority over data transfers and web pages without having to target protocols or even look inside packets.
What about VoIP /w video packets with much larger per-packet payloads?
A simple fairness queue works just as well without arbitrary constraints.
Props to Bellovin et al for arranging the numbering coincidence.

"'We must continue to work together and find a consensus on how to most effectively keep cyberspace open, accessible, affordable and secure"
Lets see it still costs me > $1/min to make international calls.
It costs me nothing to transfer information over the Internet to any destination in the world.
