How you're going to set up an arbitrage market in a livestock currency is beyond me,
No different between how it is right now: bid and ask... doesn't make any differences if the currency units are oxen, camels or bitcoins (but, again, stay away from virgins, they are perishable and highly volatile)
but if you can breed a camox/oxmel even right now, you'd do pretty damn well.
Problem to be approached when the time is right - don't need to actually do it, just suggest that there is a possibility (based on the existence of mules) and create "futures for astute investors". Hell, no different than Goldman-Sachs is doing for Facebook
Would cross-breading fail, I can always fall back in creating an investment fund, with fractional parts for the investment units (e.g. 23% ox, 65% camel and bitcoins for the rest).
Oxen dried dung works quite well, and is frequently used in South & South-east Asia. That said, following the collapse of society, I don't think you'll be terribly worried about being carbon neutral.
Don't take me wrong, I won't be worried a bit about being carbon neutral, but... you totally miss the point: the genius salesmen don't follow markets, they create fashions, buzzwords, demand - thus they create markets.
Zombie on arrival. It will be included in the crapware installed on every computer the "innocent" people buy from them and the opt-out will be painful.
^This^ is just to demonstrate that coin-only operated park meters, affordable and livable are 3 different things (with the cited "livability" is rated on: "a widespread availability of goods and services, low personal risk and an effective infrastructure").
Call me out-of-fashion, but I don't find much of a bother to still carry $1/$2 coins in my pocket.
(I really hate this morning, let's waste some time on/. Don't say I didn't warn you)
TFA - contrast (with things taken out of the context)
This goal will be achieved with IXV, which is the next step from the Atmospheric Reentry Demonstrator flight of 1998. More manoeuvrable and able to make precise landings, IXV is the 'intermediate' element of Europe's path to future developments with limited risks.
Then
The 2 t lifting body will attain an altitude of around 450 km,... The craft will then descend by parachute and land in the Pacific Ocean to await recovery and analysis.
Precise landing with a parachute, in the biggest ocean, awaiting then the recovery... yeah!
... and street parking meters only take cash where you are? Welcome to the 1980's guys.
Yea see... they work. And many Aussie councils tend to try to do the best with their budget - they seem to be somehow successful (with 4 in the first 10 most livable cities in the world). Seems like '80 were better times, innit mate?
yup, ox and bitcoins and virgins - i'm going to be rich..
I deal in camels. Oh, and my advice... get rid of virgins, they tend to loose their value quite fast.
So all parent is left with are Bitcoins?
Not necessarily. You see... once the financial world is gone, I plan to open a currency exchange. You know... eg ox/camel exchange rate? I have huge plans... derivatives (cross-breading) and ropes-tethers-and-other-bonds. I even consider futures and high frequency trading, but I still need to think a bit more.
USD don't seem so bad after all, at least you can burn them to keep warm.
Well, with camels, you can always burn their dried dung (not sure about the oxen, but may work as well). In any case, the fuel is renewable and carbon neutral.
Being able to "shoot down cruise missiles and artillery shells" assumes that they can aim. We know from the Regan administration and their StarWars program that aiming is often the hardest part.
What can go wrong, would the laser shot miss it target?
Nah. Wrong question. The really important one is: books being useful to as many as possible?
TFA:
Speaking at the official launch, Kristian Jensen, the Library’s head of Arts and Humanities, said: “This process allows books to fulfill their original aim of being useful to as many people as possible.”
I thought that is already understood: the copyright should be extended forever, for the profit of the grand-grand-...-grand children of the author (too bad if the author sold the rights to the publisher... but it's irrelevant for the usefulness of books, isn't it?).
Besides, digitization comes with the risk of exposing these "as many" to words, facts and attitudes that are quite sensitive today. I hope that Google will take note: even more recent pieces needed a "translation" to make them politically correct.
Again: can we let the Tea Party and Michele Bachmann be hurt if indiscriminate digitized papers of the time showed that the founding fathers did own slaves (and, possibly, more than own)?
Sounds similar to SELinux's TE and RBAC. But it would be awesome if they're easier to work with.
Hmmm... something tells me that there's more to it, but I'll need to try it to understand more (RBAC is about decomposing the access and defining/assigning rights to elementary resources/operations. VSys seems to come with an element of composition).
TFA
"In contrast to these tools and their variants, the goal of Vsys goes beyond defining ACLs [access control lists] for privileged commands. Vsys is meant to facilitate the composition of existing tools to build isolated operations," the paper states.
All that aside: The simplified rule of thumb for sound at audible frequencies, for a spherical waveform (such as that emitted by a phone), is that sound falls off at a rate of 6dB for each doubling of distance.
With directional elements, the wave-front is no longer spherical - assuming a beam (plane-wave front), the exponential attenuation (due to absorption) holds. But, you are right for the back-scattered sound - this will degrade much faster not only because of the absorption, but also because it won't be an almost planar wave-front anymore.
And we only care about frequencies in the audible range, despite the implication in TFS, or it will be completely unable to work with existing phones (which is the main point of the thing to begin with). To wit: Combine Nyquist theory with the shitty analog electronics and 48KHz (at best!) ADC/DAC in a phone, and the resultant system must be either audible to a sufficiently-close non-damaged human ear, or else be completely non-functional.
The human ear is able to pick up to 20 kHz, and people over 40 are able to hear at most 16-18 kHz (if ever). This is why 22 kHz is meant to be the absolute upper frequency to digitally encode on an Audio CD and thus 44 kHz the maximum sampling rate required for "absolute audiophile perfection".
All the above as an estimation for what frequency a ADC/DAC in a smart phone can be capable of: my guess - an upper limit of 30-36 kHz. Given the amount of information that a NFP requires (hundreds of bytes, including an encryption key), the fact that tone encoding is not sensitive to amplitude/power variations, the fact that directionality of sound is easier to implement than in RF, the band between 20 to 30 kHz may be just enough to implement the NFP with a better protection for eavesdropping than using radio. This will raise the cost for the eavesdropping party, thus requiring a higher level of motivation than a near-field type of payments usually offer - most of the NFP services I know are capped to $50-$100/payment.
It therefore must have strong security (whether cryptographic or otherwise), or it will fail and be exploited. And if it does have strong security, it doesn't matter if it's recordable or not, since any recovered data will be useless to the eavesdropping party.
I don't argue with that. It is only a (almost academic) discussion which transport can be implemented cheaper: I argue that the acoustic one may be the one - but I'm not sure.
I don't know... might work better than radio waves - the attenuation of RF in air might not beat the attenuation of sound waves. The higher the frequency, the higher the attenuation of the ultrasound in air (dry air: 0.6 dB/m at 50 kHz, 1.8 dB/m at 100 kHz). Add some directional elements, use a small emitting power and what's not in direct line of emission might be drowned by noise at a distance of 0.1-1m.
And, on a side note, this is oddly reminiscent of Phreaking
Hmmm... yes, but I think in this case the danger will come from rogue bats flying around that pay terminal (hold you fire, it's just a lame joke)
Hey, didn't British send their common criminals to Australia, religious nuts and crooks to America? With only two latter conditions being hereditary? Australians were supposed to be the sane ones!

a. What does a mole have to do with anything? You don't have a mole of neutrinos.
b. Neutrinos don't tend to care what gets in their way, and move really fricken' fast. I doubt 300 km matters much.
How many possible sources of "noise" you have in 300 km? (i.e. radioactive particles that just decided to emit a neutrino?)
c. Neutrino beams are possible and do exist.
[quotation needed] I can't imagine how you manage to make sure your neutrino emissions goes only in a predetermined direction (thus, actually build a beam from them), I'd be happy to be shown how.
d. Yes, there are lots of sources, but those sources can be measured and controlled for.
Hmmm... are they now? Can you control all the radioactive decays that lead to a neutrino somewhere in those 300 km? (this assuming you can tell the direction of an incoming neutrino that interacted in your detector).

Thanks God!!! From now on (and because of that), those moons do have some chances to develop life...
Just made me curious: how many visitors/minutes on /.?
That goodness we have pope like you to judge the value of other peoples time.
You're no different the people who try to dictate what should be allowed on TV, which websites should not be allowed, and what god to follow.
A matter of personal opinion is trying to dictate? Suggestion: go have a nap, let me waste in peace some time and bandwidth ... on /.
knowing what they mean can let you in on the hidden life of the gizmos you buy
They tell you when you buy them.
Don't feed them after midnight. Keep them away from water. Avoid sunlight.
Thought that was common knowledge.
