The first bomb causes rescuers to flood to the scene. The second bomb is targetted at those people: police, paramedics, firemen or whatever. To maximimse the result you need to observe when those people have arrived and then trigger the second bomb. A timer would be less effective.
The police will want to take the network down before they send the rescuers in. If the bomb detonates when the network goes down, it will be too early to catch the rescuers.
He's accused of having sex with an unconscious woman, knowing she would not have consented had she been awake. That's rape in UK. The case has been through judicial review here, which confirmed it.
How did you interpret "I'm a moron" if not as an attack on his own intelligence?
There used to be a gap in the fossil record. Now there are two gaps.
Block-chain based voting has been implemented in other coins, notably Qora, for many months. It's an interesting way of running a vote, being distributed and trust-free, anonymous and public. No issues with corrupt officials miscounting.
It is the psychology and politics that Bitcoin changes.
The strength and weakness of a fiat currency is that the bank can create more whenever it wants. The banks say this is a strength because it allows a country to inflate its way out of recession. It's a problem when different countries want to share a currency because they have to decide who has the power to create it. Whoever has the power has to be trusted not to abuse it by creating money for bad reasons. Virtually every fiat currency that ever existed has eventually been debased into worthlessness by its government in order to pay for a war.
Bitcoin changes this by being distributed and decentralised. This means no-one has the power to issue more of it on a whim. New coins are created according to a fixed schedule. Hence there is no need to trust any central bank, and different countries sharing it don't need to trust each other not to debase it. They can just opt into it individually. They don't have to agree about policy.
It took a billion years for prokaryotes (simple single-celled life) to evolve. Then another 1.6 billion for eukaryotes (more complex, but still single-celled). Then another billion years to get multi-cellular life, and another billion to get primates. We have no idea whether these steps always take that long, or whether we're unusually fast or unusually slow. I find it easy to believe that getting to multi-cellular life usually takes 4 times the 3.6 billion years it took us, in which case it is longer than the age of the universe. In other words, there could be lots of slime out there, but not much intelligent life.
There would still be some intelligent life, but if it's rare, it's probably too far away for us to detect it (or vice versa). I see no reason think whoever is first will have a drive to colonise the galaxy. It might make more sense to upload themselves to virtual reality instead, and have all the space they need. Especially if they've achieved zero population growth (arguably a pre-requisite for a civilisation to survive more than a million years).
Whatever: Fermi's Paradox isn't a paradox. Anyone who understands enough to see why it's an issue should have enough imagination to explain it away.
The reasons for it being female (or, indeed, having a gender at all) are more or less explained in the film.
Sometimes she gets naked first. Sometimes they record one half of the session and leave her bit out.
Sometimes they leave her out and then claim your partner was 13 years old. It doesn't matter that it wasn't true; a video of you wanking in front of a child will get you judged in the court of opinion and potentially ruin your life. It's easier and safer to pay, if it's not too much.
I hate all the victim-blaming that goes on here. This is a confidence trick. It relies on taking the time to build up trust.
Nxt is a proof of stake coin. There is no mining, hence no "insta-mine". The initial development was funded by crowd-sourcing, which anyone in the public could contribute to in exchange for an early stake. 73 people did. That was roughly a year ago. Since then the coin has had massive development, with many innovative "2.0" features being added, including messaging (with/without encryption), an asset exchange and a marketplace that runs trust-free. More features are on the way. As such it in no way matches the profile of a ponzi-coin, which are generally clones of Bitcoin or similar with no innovation or serious effort put into them.
LockStep, by Karl Schroeder, is built around it, and not just for long journeys. Not a great book, but definitely worth reading as an exploration of cryosleep.
Surely porn will fall foul of the uncanny valley? if you use computer models (as games will), the people will have dead eyes and unrealistic skin and generally not up to porn standards with live human models. If you use live human models, then you are stuck with whatever PoV the camera had when recording.
The card doesn't contain a battery.
Baking potatoes don't need to be peeled or chipped, and they don't need oil. Wash, prick and bake. Season them if you must. Eat the skins; they are nutritious.
The Apple watch has wireless charging, which should help keep it charged, and I hope it can sync time from your iPhone (which hopefully can sync from the network), as that should avoid any need to fiddle with it if it does go flat.
(My quartz watch uses solar power to top up its battery, and syncs time with a radio signal, so it hasn't needed any attention since I bought it.)
For me the killer feature would be payment by NFC, supposing the nation's infrastructure is up to it. For example, it should save me having to carry a pre-paid bus card. (Having NFC in a phone isn't enough for convenience, because getting a phone out isn't any harder than getting a wallet out; but my watch is already out.)
Other people want vibrate notifications for incoming messages and the like. Having the watch alert if it gets too far away from the phone would be useful for people who leave their phones behind, and having the phone lock/unlock depending on its proximity to the watch would useful for people who are concerned about their phones getting stolen.
Whether any of these features is included in any given smart watch product is another matter.
Wikileaks reused passwords, which is a basic security error. The Guardian journalist should not have published the password for his private sample anyway; but he had no way of knowing it had been reused on publically available archives.
from the profits from Guardians of the Galaxy?
True. Although removing the battery is itself a suspicious act that has helped persuade a jury that the accused was up to no good. Better to leave the phone at home (or wherever your alibi is).
Many people need the passwords to be available from a variety of machines. Their desktop, their phone, their tablet, etc. That's why the (encrypted) password database needs to be synced across the internet.
Do you think printing dollar bills has no environmental impact? Or forging pound coins? The cost of mining Bitcoin does not depend on how much it is used or how many new coins are created, so the current costs are about as bad as it gets, even as it scales to supplant other currencies which are less environmentally sound.
They could use Bitcoin or Nxt.
The expected lifetime of a fiat (ie, issued by government and not backed by anything) currency is about 30 years. You'd be surprised how many national currencies have failed within our lifetimes.
See http://georgewashington2.blogspot.co.uk/2011/08/average-life-expectancy-for-fiat.html. "Twenty percent failed through hyperinflation, 21% were destroyed by war, 12% destroyed by independence, 24% were monetarily reformed, and 23% are still in circulation approaching one of the other outcomes."
There's a brief review for "Unlock with WiFi" here: http://lifehacker.com/5829514/unlock-with-wi-fi-saves-you-from-tedious-phone-passwords-when-youre-at-home. The review is dated 2011. Apple's application date is 2012. Apple were later.
"Unlock with WiFi" is the one I use. It sets the password to blank when it can see my home wireless network.
To make money from mining now, you need ASICs - application specific integrated circuits that are custom-designed to mine Bitcoin. They are much more efficient than GPUs at mining (and useless for anything else).
If you spent $800 by buying Bitcoins on an exchange, you get more coins than by spending the $800 on electricity for mining. If/when the price went up, you still be better off.
Mining generates 3,600 new coins a day, so 30,000 coins is less than 9 days worth. It's not a big volume.
The keys for these coins were held on the machine that ran the Silk Road. No-one is claiming to own them (because they would be incriminating themselves if they did so), so there is no-one to try. The chap they think ran the Silk Road has his own stash of coins, which won't be sold until after his trial (and then only if he's found guilty).
He's accused of rape. Rape is a serious crime.
Bitcoin lets you send money where-ever, and stores the balance in the block-chain, and does it all cheap, transparently and trust-free. If the bank isn't doing any of the clever stuff, why do we need it at all?
Do not send your coins to random addresses. That is not a good way to destroy them.
The correct way to destroy bitcoins is to send them with a transaction script that just has OP_RETURN. This type of transaction is provably unspendable, so there's no risk that someone secretly knows the private key and can resurrect them (much) later. This is also kinder to the network because it can be pruned from the "unspent transaction outputs" table.
Deliberately inserting virus signatures into the block chain has been talked about for a while. For example, http://pastebin.com/ct2WHUK5. Nor is this the first time it's happened, eg https://bitcointalk.org/index.php?topic=559365. Unless there's evidence to the contrary, I would expect this to be deliberate.
That will happen on both consoles.
Bitcoins have value for the same reasons gold has value: both are hard to fake, available in limited supply, and facilitate trade. Bitcoins are hard to fake because there is a public ledger recording who owns them. Anyone can write updates to the ledger, but no-one else will believe them unless they have all the right digital signatures etc. That makes it almost impossible to spend coins you don't own.
However, because Bitcoin is distributed, it's possible to get two versions of the ledger, both equally valid, but different. In that case miners effectively vote for which one wins. To prevent someone stuffing the ballot box, votes are made expensive, and that's where the "proof of work" comes in: the winner is the (valid) ledger that has had the most CPU cycles spent on it.
So part of the complex number-crunching is for validating digital signatures, but most of it is for achieving consensus about ordering of updates.
The regulatory environment isn't as hostile as you seem to think it is. Both USA and UK governments consider Bitcoin to be legal, and issue guidance on how to pay taxes on profits you make with it.
Story is weak, and the game really isn't as good as the review implies. You can only jump or climb if the game has decided those actions make sense there, and you can only use rope arrows in marked places. It's frustrating how often plausible routes turn out not to have been thought of by the designers.
On the other hand, it's better than some other reviews. Dishonored is more fun, but at least Thief is a genuine sneaker. Dishonored devotes too much of the UI and game-play to combat.
Why repay? The Kickstarter folk were promised an early dev kit, which they were given, and that's the end of their involvement. People confuse funding via Kickstarter with buying shares. Kickstarter is used by companies that want money and don't want to give up their shares or control to get it.
Sony have already said theirs won't be available in 2014, and Microsoft seem even further away.
When you buy bitcoin from a reputable exchange, it will be subject to Know Your Customer and Anti-Money Laundering laws, so the coins are known to belong to you. Every transaction afterwards is published in the block-chain, which anyone can access. So bitcoin is actually very traceable, at least compared to cash. Whether anyone will bother is another matter, but if you get audited the data trail exists and can be used, either for you or against you.
And adverts. Don't forget the adverts.
Teach the controversy!
The Bitcoin protocol does not have any notion of "stolen", and nor does it have any central authority that could label coins as such. (Such an authority would have enormous power, and power corrupts; Bitcoin was invented as a distributed mechanism precisely to avoid such centralised power). Hence coins which one person claims are stolen, can still be freely traded under the Bitcoin protocol.
In theory you might try to reclaim stolen coins using conventional legal means. That would require identifying who currently possesses the coins so they can be reclaimed. That can be tricky because the coins are stored in (effectively) a numbered account and there is no registry that maps account numbers to real-world names and addresses. So for example, if the thief uses stolen coins to order a pizza, you might be able to discover the address the pizza was delivered to. That would require the cooperation of the pizza vendor; and if the thief holds onto the coins for 10 years without spending them there is little you can do for that long. Alternatively, you might be able to discover the IP address the coins were acquired through. Generally, there are things you can try, but there are also things the thief can do to defeat you. Identifying a Bitcoin thief requires technical know-how and resources (or a stupid thief).
In addition to technical challenges, you would have to prove the coins were stolen in some court that has jurisdiction. Lots of legal issues there. Arguably if the thief did not have good legal title to the coins, they couldn't pass good title to the pizza vendor, and you could reclaim the coins from him (much as you could reclaim a stolen car even if the current possessor had bought it in good faith; it would still be your car and your bitcoins). However, it's not clear Bitcoin works like that; cash doesn't, and Bitcoin was intended to work as cash, with transactions being irreversible.
Some of the sums involved in recent thefts are large enough that I would expect all legal and technical avenues to be pursued in recovering them. So maybe MtGox will get its coins back. It won't be quick, though.
You can already get insured storage of bitcoin. Eg https://www.elliptic.co/. They charge 2%/year. Presumably the rates will improve as they gain confidence with their security, and competition grows.
You can verify that a transaction has valid input and outputs, that the inputs contain the money specified, and that the signatures are correct so it is the owner of the coin that is spending them. You can do that yourself, locally, and it takes almost no time.
What that quick verification doesn't protect you from is double-spending. If the punter has a mate in a different country who tries to spend the same coin at the same time, only one of them will succeed, and it may not be the one who spent first (because "first" depends on network delays). Waiting 10 minutes mitigates that risk, and waiting for 6*10 minute confirmations generally makes it negligible. For small transactions, the risk of double-spending is low because the benefit is low, and its tricky to set up and you risk the wrong transaction winning anyway, and if it succeeds you probably won't be allowed in the pub again, so you might as well just do a runner instead.
Eventually vendors will probably be able to get insurance against double-spending, and we may even get "green-listed" bitcoin addresses which some trusted entity promises will not double-spend. There is still a role for banks, insurance companies and credit card companies in bitcoin, if/when they want to get involved.
(I don't know what that pub actually does.)
I'm not there either. I still have a Facebook app pre-loaded on my phone, which I can't uninstall. Now it repeatedly asks for updates, which I repeatedly refuse. The nagging is annoying.
This is not aimed at Bitcoin. It's aimed at illegal uses of Bitcoin. These coins are being treated no different to any other asset of a criminal enterprise. They're probably auctioning the server hardware too.
The Feds like Bitcoin. Check out the Senate hearing. They can see the benefits as well as anyone.
I want Pay By Bonk on my watch. It doesn't belong in a phone, because getting a phone out of you pocket isn't any easier than getting your wallet out. (By all means use the phone as a UI for the watch, though.)
@Mike Moyle: he said "many of them", not "all of them", so a few exceptions don't refute his point. And although gold etc has been used in the past, more recent history shows that many currencies moved off the gold standards because it is problematic. (Although not because gold has intrinsic value, but because governments found themselves unable to regulate its supply. They really want inflation to run at 2%/year or so, which is easy to arrange by printing more money but hard to arrange by mining more gold.)
That's my understanding too. (I don't have an XBox to check.) Apparently the juddering is most noticeable when the TV is outputting smoothly scrolling text, and when the 50Hz TV input is snapped alongside a 60Hz game. The XBox repeats every 5th frame, which some people notice and others don't.
