The radio receiver for the keyless entry door locks ought to be able to idle on microwatts, and wake up and use milliwatts when it needs to spin up the computer that determines whether a received signal is actually the right key to open the locks.
I would like the ability to say to my ISP "I have a little traffic that I would really like to be delivered on time every time. It's not much, and I'll pay you a little bit extra for the extra effort." (Gaming/skype traffic).
On the other hand, someone downloading large files or streaming netflix (with its deep buffers) would like the ability to say "I'm going to be transferring lots of data, but I really don't need 100ms latency for it; long latency on my netflix stream is fine, so long as the time-averaged bandwidth is enough. Since you can give me what I want with less effort per megabyte than the guy who wants 50ms latency, I'd like to pay less."
Especially if you want to show the world the crimes and torture of your government.
The thing about the US is that we recognize that our government doesn't always follow the law. Just because the government is going after people for airing its dirty laundry doesn't mean that the government is being either legal or constitutional in doing so.
No Healthcare, Death Punishment, many believing in Creation, I mean, that are medieval thoughts.
There is quite good health care in the USA. The only difference is that you pay for it yourself, rather than out of your taxes.
The death penalty is something I disagree with, but it's hardly common, and is on the decline.
Rejection of evolution isn't unique to the US. We are unique in that the population holding this particular superstition happens to be Christian and has been here for a while, but it's also common in the Muslim populations in Europe (which I presume you call civilized).
Come visit. We realize our government does some stupid stuff, and we'd like to change that, but our country isn't defined by its government.
Banning calls for "racial hatred" is a slippery slope. Where along the line do you start arresting people?
Also, I think you mean "penal code"; "penile" is an entirely different word.
As someone who's been involved with universities for a while: you cannot get arrested by campus police for trespassing on most campuses. Public universities are public property, and most places in most buildings are open to the public. (Of course, if you wander into a professor's lab without his permission, you're likely to get in trouble.) At the University of Arizona where I got my doctorate, homeless people would regularly come to the library to use the computers for internet access.
Many private universities incorporate substantial tracts of public land (they consist of buildings on public streets), or are on private land but are open campuses. Only a few campuses are truly closed campuses where visitors are not welcome; those are no different than any other private land. So I don't know quite what you mean.
I don't think you understand the concept that the xkcd advocates.
The ars technica article is pointing out that context can grossly reduce the entropy in any given search space. If you're going to test combinations of words from different languages, for instance, you shouldn't bother with "crotalus fthagn" or "Cthulhu atrox" until you've already tried "crotalux atrox" and "Cthulhu fthagn". The point is that you can't beat the password crackers by picking something from an obscure search space -- in other words, it's a classic point against security by obscurity.
The XKCD is making a different point: that passwords comprised of unrelated words deprive the attacker of such information and are resistant to attack not because of the obscurity of the search space in which they're found, but because of its size. Perhaps 44 bits of entropy isn't enough to defeat extensive computational resources, but the point is that six words chosen out of the dictionary at random, all in lowercase, with spaces between them is a better password than "Cthulhu fthagn" because modern datamining techniques mean that it's likely to appear in someone's dictionary after all.
This is a little deceptive.
Those supercomputers are made of x86 CPU's and GPU's (mostly). Those things are optimized for floating point performance and memory bandwidth, and have complicated memory hierarchies to keep all of the compute bits fed.
Computing hashes requires none of this, which is why an ASIC built for Bitcoin mining is so much faster than a GPU, which is built for other things. It's true that all the physicists in the world couldn't out-hash the Bitcoin network with our supercomputers, but that's not a realistic attack avenue anyway; the thing to worry about is the NSA spending $1 billion on ASICs.
You don't always have internet access. Wifi doesn't work, people's authentication systems don't work. Sometimes you want to draft replies to people's letters on an airplane and send them when you land. In short, there are lots of reasons why you can't get to The Cloud to see your mail.
Mail is lightweight. Why *shouldn't* I store my mail locally, so I can get at it no matter what? What benefit do I get from using a webmail interface over an IMAP client?
Yes, I know that things like gmail offer imap access, and that's what I use. I completely understand why companies like Google are pushing "everything is inside the browser" -- it locks people in. But what I don't understand is why people are willing to go along with it.
I'd rather put up with two hours of airline passengers than thirty minutes of the sorts of respectable citizens that ride the bus in Washington anywhere east of Rock Creek Park. People eat fried chicken and throw the bones on the bus floor and guffaw at each other; last time a lovely lady told the driver to "shut the fuck up and drive" after he told her to stop bothering all the other passengers.
Even with a perfect link cell connections are shit. Compare what your cellphone sounds like to Speex 16kbps; it's remarkable.
The more people accept Bitcoin for stuff, the more stable the price will be -- when it becomes more of a currency and less of an investment.
... until the next time when Congress gets collectively drunk and decides to shut down the government, and someone puts up Faraday-cage Barrycades* around the GPS satellites. Yes, it sounds crazy -- but so did the Barrycades around the memorials at the National Mall, until the Feds did it.
Point is, governments occasionally get crazy and do crazy things. So do the European ones, of course, but it's nice to be able to use satellite navigation even if one particular government goes crazy and throws a tantrum.
*Referencing Barack Obama's nickname, name given to the barricades erected at random around public property to make the government shutdown look bad
Nobody wants to invade Europe because Europe is most valuable, to pretty much everyone else, as a peaceful trading partner.
We are your friends. Actually. We've been your allies for a long time and we've been faithful throughout. I'm not sure what we'd have to do to improve your impression.
Stop being a bully. Listen to your friends, rather than deriding them as "Old Europe", when they tell you that the Iraq war is a shitty idea.
