Dedupe should NOT work if every file is encrypted.
IF they do the crypto right, even if the exact same file is being encrypted it will NOT result in the same encrypted file. If it does it means they are doing the crypto wrong!
And with strong crypto it becomes exceedingly unlikely that you'd have duplicate blocks - assuming a block size that's 512 bytes or larger. If you find significant numbers of duplicate blocks it means something is wrong somewhere. What are the odds that 512 random bytes will the same as another 512 random bytes? If you flip a coin 4096 times, what are the odds that you'll get the same result sequence again if you flip a coin another 4096 times? That's basically what decent crypto is aiming for - it looks random. If it turns out to be far from that random, you've found a flaw in the crypto or the system.
You might have dupe blocks in the metadata of the file system that's handling those encrypted files but that might not be good enough, or you might not want to dedupe those anyway...
Of course for 100% backups they'll have duplicate blocks but you're not supposed to dedupe backups...
I fail to see how this feature will be accurate enough because FaceBook users are not all that consistent.
Yeah I have a friend who likes practically EVERYTHING. OK I exaggerate, it's only 6000+ likes. Another likes 3000. And another likes 70.
FWIW I can't even find stuff I know is there with Facebook's normal search. Whether on my profile/timeline or a friend's. And it's with the exact keyword match too. Only stuff not older than a few days shows up. If I manually search for it, it's there.
Fetal DNA can enter a mother's brain and remain there for decades, according to autopsies of female brains.
To investigate this, Nelson and her colleagues autopsied 59 brains of deceased women â" 33 of whom had Alzheimer's disease. They amplified the DNA that they found, creating many more copies, and looked for the presence of a male Y chromosome.
They found it in 63 per cent of the brains. This male DNA showed up in many different brain regions and some of it had been there for a very long time: one brain that contained the male DNA was from a 94-year-old woman.
Many mental traits are genetic, so it might be a very mind altering experience;).
If that's the case why not require the US reported earnings to be limited to whatever that's taxable in the USA? So if you're going to count it in the USA you're either going to have to bring the money in to the USA, OR you could leave it in Ireland, but pay the tax as if you earned that the USA.
If you transfer 1 billion dollars to Google USA and Google USA spends that 1 billion dollars, does that 1 billion dollar show up as taxable profit? I should think there's a way of spending it so it doesn't become profit right?
And if it doesn't show up as taxable profit then it could mean that Google doesn't have anything in the USA that they want to spend 1 billion dollars on.
Also the billion dollar building might be worth more in the future than USD1 billion (inflation and all that).
But where do they get the zero days from? Do they write them themselves?
In the real world why wouldn't a malware author make sure his/her malware passes all AV tests? Then that author's final released zero day wouldn't be detected by any of the AV software out there.
But how do they test for effectiveness against zero-day attacks? Where do they get the zero-days from? If I'm a virus author I'd test my zero day with one of those websites ( http://www.makeuseof.com/tag/7-reliable-sites-quick-free-anti-virus-scan/ ) that scan for viruses with practically all the AV software in the market.
So the zero day when finally released will NOT be detected by ANY of them!
Maybe what an AV vendor could do is secretly work with these AV websites to detect suspicious activity..
Total amount solar energy hitting the earth each day: 1.05479452 * 10^ 22 joules World oil consumption 80 million barrels per day = 4.689216 * 10^17 joules. USA oil consumption 20 million barrels per day. (assuming 1 barrel of oil = 5861520000 joules ) From: http://en.wikipedia.org/wiki/World_energy_consumption Total fossil+nuclear energy consumption per day = 1.23641753 * 10^18 So solar entering Earth (nonreflected) about 22500 times the oil consumption, and 8500 times fossil+nuclear.
However we're not the only species on this earth that needs solar energy so 8500 times might not be that high from that perspective;).
How do you propose to manage all the square kilometres/miles of ocean required to grow your algae on? You'd still need a lot of surface area assuming the algae needs sunlight to grow.
These biofuels are basically solar energy. From the efficiencies you can work out how much surface area you need - whether land or sea.
They might be less efficient than solar panels but unlike algae and plants solar panels don't build and repair themselves. But if they are too inefficient, the area required becomes a big issue.
You could use mobile networking and a personal smartphone to get the subcontractor's output, then transfer it from the phone to your work PC (whether directly or other means). That way there is no direct network connection between your workplace and your personal equipment.
If this answer is acceptable please pay me USD10[1].
If you get tendonitis of these tendons, the inflammation can compress the median nerve, which is what causes carpal tunnel syndrome. It makes some sort of sense that strengthening this overall group of muscles can improve matters
The other approach is to strengthen/heal the affected nerves - e.g. with methylcobalamin and a bit of some other B vitamins (but not too much B6 as it can cause nerve problems too!).
As far as I know bodybuilders and athletes do grow larger wrists and tendons over time, as such some of these problems might just be an imbalance in growth - tendons growing faster than the other parts can adapt. And that's why I'm not too keen on stuff like surgery to cure this sort of problems - it can help but it can cause other problems too.
The PvP was more interesting too[1]. Was... It's kinda dead now due to there being a lack of players, in GW1 there is no way to queue for PvP while doing other more interesting stuff in game instead of just standing around waiting for enough people to stand around... To be fair it's not so easy to allow queuing for PvP while doing something else - because a build that works in PvP might not work well in PvE (but that's where the other 7 heroes in your team come in I guess;) ).
I've seen a fair bit of GW2, I don't think I'd like it that much. I agree with you that it feels more WoW like. To me GW2, WoW and SW:ToR are more similar to each other than to GW1. Will be a shame when they pull the plug on GW1.
How can I now trust symantic to find a zero day and protect my systems when they have been unable to find things like red october and flame for years
You can't. The "Detect Malware Problem" is harder than the Halting Problem (which is unsolvable in the general case). You can use heuristics for specific cases and typical cases but you are not going to defeat a competent determined attacker.
I don't bother running AV on my machine because the AV makers are more likely to screw up my machine than a virus is (they seem to screw up every 2 years or so). Slashdotters have flamed me and accused me of being stupid, but it works for me. I configure my browsers (and other network apps) to run different user accounts, so if my Slashdot browser gets pwned the malware still needs a privilege escalation exploit to affect my banking browsers and other stuff. And I never log in using the user accounts that my browsers run as (they are like the "nobody" account in unix- you can hide accounts in windows so they don't show up on the login screen). I can upload stuff to VirusTotal if I'm suspicious of it. I don't download and install stuff very often, so why pay the AV resource cost every day, and also risk the AV screwing up your machine? The stuff that's not found by VirusTotal is still not going to be found if I installed AV on my machine with all the costs and risks.
This approach is not suitable for normal users of course, there are many inconveniences for example the browser can't update itself automatically - doesn't have the permissions.
We're still in the dark ages of security. Lots of people here think too highly of Unix/Linux. The standard Unix security model isn't that great. With what we know in modern times, OS and application sandboxing could be a lot better. In some ways the mobile OSes are ahead of the Desktop ones in this area.
Even getting the application to _propose_ its desired sandbox upfront is better than the AV approach ( as I've proposed: https://bugs.launchpad.net/ubuntu/+bug/156693 ). A sandbox is like "solving" the halting problem by forcing the program to halt after a time limit. Basically you can easily solve the halting problem if the operating system forces the program to declare upfront how much time it wants! An application that asks for too much becomes suspicious. You can have 3rd parties audit the sandbox request and approve+sign it.
If I were a malware author I think that sort of thing would make my life more difficult than the current AV concept. Of course if I were a malware author I might write my malware in stuff like perl, ruby and python - just to see how the AV makers cope with TIMTOWTDI taken to the extreme:).
And because of the commercial unsuccessfulness of their game it may make sense to have it all on one planet/server. When I last trialed the game, the server populations were rather low. Finding people to do stuff with wasn't that easy. Yes there were people around, but only a subset of those would want to team up with random people. So if you wanted to be gay in game and were looking for like-minded people (for more fun) you'd have even more difficulty if you weren't all on one server.
FWIW when the trial ended I didn't really feel a sense of loss. So even with the F2P options I'm not sure if I'd bother trying it out again. The PvE and PvP gameplay was boring to me. And yes I've had someone show me a lot of lev 50 PvP, hutt ball and all that for a few weeks. GW2's WvW stuff looks more interesting but if their player numbers drop that big WvW map is going to be an even bigger ghost town unless they can have decent AI NPCs to help out if there aren't enough on one side.
But managing servers from your house can become much easier with a 1Gbps low latency connection.
Find out that for some unfortunate reason you need to push an entire VM to the server farm? Not such a pain at 1Gbps. Or maybe it becomes faster to push a known working prebuilt machine to the farm than to rebuild it there (and hope it works the same). The farm provider may charge you more $$$ for the gigabytes of transfer, but it could still be worth it.
Or you want to make an offsite backup of data in your "Cloud"? Much easier at 1Gbps.
If Google manages to make money from their ISP stuff, it makes it harder to say "I can't make money 'giving away' gigabit internet connections at that price". And I think that's Google's plan - they're not going to subsidize it with their ad money, they're going to prove to the US people and the regulators that it's possible to make money doing what they do.
I don't think Google really want to be in the ISP business, but their future plans depend on the USA having improved ubiquitous internet connectivity - fast always-on connections with no restrictive quotas.
But if the ISPs don't get off their butts, Google might just go into the ISP business in more and more places. I doubt the ISPs would like that.
Actually the nutritionists and doctors who have been giving them bad advice for decades also share a big part of the blame. That includes the USDA and their stupid food pyramid (but they are the Department of Agriculture not Health so no surprise their priorities are a tad different). The restaurants and food industry providing super huge portions, low fat + high sugar also aren't helping (esp when combined with typical parents training their kids to finish up everything on their plate even if they feel full). Then there's the education system.
Not all rich countries have a big obesity problem: http://www.nationmaster.com/graph/hea_obe-health-obesity So why are they different? You can put some blame on the individuals, but when a whole country is full of obese people doesn't it make you wonder what else is going wrong? Not all those fat obese people are stupid, I see plenty of smart fat people. So who has been feeding their minds and thus bodies with garbage?
The people who say "it's simple" and just a matter of calories are also to blame. Because it is NOT simple. Not all calories are the same. Anyone who thinks so should try filling up a gasoline car with diesel or vice versa. If there's a difference for something relatively simple like a combustion engine, it is stupid to assume that there's no difference for human metabolism. We don't digest cellulose well, but glucose goes in pretty fast (along with simple starches), fructose is mainly processed by the liver, alcohol by liver and brain, protein needs to be broken down to amino acids, and not all proteins are easily digested. And certain foods make you fart (and if you fart methane it means yet more calories are escaping;) ).
From what I see only a few nutritionists or scientists do studies where they measure the shit that comes out from their test subjects. The rest measure what goes in, oxygen consumed or exercise done and a few other things but they don't measure the excreted shit or its caloric value. So their studies are flawed.
Would this mess with your digestion by diluting your stomach acid?
That's not a problem if the goal is to lose weight.
For similar reasons I never understood the logic of nutritionists who ask fat people to chew the food properly so as to digest it better.
I can understand if the reason is to slow down the consumption so that the stomach has time to send signals to your brain that it is full, but digest food better? You want to slow your consumption? Drink plain water during and after eating. Don't drink too much or you'll feel ill instead of full.
Anyway half of it is genetic and the other half is taking too much sugar and sweet stuff (I won't be surprised if the artificial sweeteners screw up your metabolism too).
