Perhaps we need the ability to add meta data to web content that informs google of keywords that should not be used in the index. I'm not saying everyone would use such a feature responsibly, but having this option could be useful in some cases.
It doesn't help that the default way the shell processes filenames through glob patterns and command line tab-completion can leave you vulnerable to these kinds of issues.
And then set a lower u/l limit and watch your d/l speed increase. If your upload is congested, you won't be able to send TCP ACK's or protocol requests in a timely manner.
He wasn't talking about the relative difference between 1999 and 2014 GPU performance. He was comparing graphics performance on laptops to other hardware available at the same time.
That doesn't mean I agree with the OP. Mobile graphics has improved to the point that a low end laptop can actually be used to play a fair number of games, without breaking the bank in the process.
Except that we keep trying to satisfy our demand for instant gratification by spending borrowed money, and that period is coming to an end. If you can find a way to satisfy our demand without chaining people to future obligations, then sure we can all live in a utopia.
As for the Great Depression, I'll try to summarise Steve Keen, though I suggest you read his work yourself.
Have you ever seen your bank balance drop because the bank lent money to someone else? Have you ever borrowed money without spending it immediately? Banks create money out of then air when they issue loans, which are immediately transferred to someone else and counted as a deposit. This transaction represents a discontinuity in our ability to spend. It allows us to satisfy our wants and needs without first waiting for income. This increases the measured income of the seller, and our supply of money.
So our GDP equals our Income (before new lending), plus our new debt times the velocity of money. Which we then measure as our net income. Therefore the change in GDP is the change in income plus the acceleration of debt.
And this is testable empirically. Positive debt acceleration correlates with job creation and rising asset prices. Debt deceleration correlates with job losses and falling asset prices, even if the velocity of debt creation is still positive.
The period of debt deceleration experienced by most of the world recently, was sudden and massive, but it has barely removed any of the debt we have acquired. Now we have a truly staggering level of debt, more than in the Great Depression. Removing all of this debt from the system will require an extended period of debt deceleration and a negative debt velocity.
And that would work fine for you, where your bottleneck is over your last mile connection. But that doesn't help when the traffic is flowing across different network paths. For example if there's a bottleneck between 2 tier 1 providers. Only traffic flowing across that link will be affected, and perhaps only traffic from one data source will be considered low priority and dropped. The only fair thing to do in that case is increase capacity.
Full disclosure, that's not an accident, you'll find my email address all through the Serval Project's commit logs on github.
If this mentality of allowing P2P communications with phone radios becomes pervasive, then the Serval Project has been successful. Even if we don't get credit for the idea.
But I fear that this solution will still need a nearby LTE tower to manage the spectrum. I also doubt that 3rd party developers will have access to the underlying API's.
I highly doubt there will be an exposed API at the application layer, without paying the carrier in some fashion. You would still be using the carrier's licensed spectrum and they'll be heavily involved in the process.
I haven't found any information about how access to the spectrum is managed, or if this Direct mode can work without a nearby tower.
Pity, as this is exactly what applications like the Serval would like to use for long range / low power communications.
To record a single bit by changing the state of a system requires an amount of energy no less than kT, where T is the absolute temperature of the system and k is the Boltzman constant. Given that k = 1.38 × 10^16 erg/K, and that the ambient temperature of the universe is 3.2 Kelvin, an ideal computer running at 3.2 K would consume 4.4 × 10^16 ergs every time it set or cleared a bit. To run a computer any colder than the cosmic background radiation would require extra energy to run a heat pump.
So 4.4 × 10^-23 Joules minimum per bit flip * minimum of 2^128 bit flips = 1.4 * 10^16 J. Though of course our current computers are far from ideal and it would take many bit flips to test each key. Unless someone has a better source for the energy cost of computation?
The mass of the oceans is about 1.4x10^21 kg. It takes about 4,000 J to raise the temperature of 1 kg of water by 1 degree Celcius, and thus about 400,000 J to heat 1 kg of water from freezing to boiling. The latent heat of vaporization adds another 2 million J/kg. Thus the energy required to boil the oceans is about 2.4x10^6 J/kg * 1.4x10^21 kg = 3.4x10^27 J
So an ideal computer might be able to count to 2^128 without boiling the oceans (doh). It would take a 10^11 increase in energy usage per bit before boiling the oceans was impossible to avoid.
That's the problem with exponential functions, the human brain is too easily tricked. Doubling the bit length of a key doesn't just make it twice as hard to break.
Over the past 40-ish years, we've transitioned from 8-bit computing to 16-bit, 32 and now 64 bit is common. We might need pointers bigger than 64-bits eventually, but we will never need a pointer bigger than 256-bits in length.
The same is true of encryption, for the same reasons. We measure the strength of a crypto system based on the number of keys we would need to attempt in a brute force search. Sometimes we find mathematical short-cuts that weaken a crypto system, reducing the number of keys we need to try. But if we can't do that, we need to test every value.
Counting through all possible values of a 128-bit number would use enough energy to raise the oceans to 100 decrees Celsius and then convert all of the water to steam. This is an amount of energy that we might be able to do harness one day, if we could be bothered. Counting through all values in a 256-bit number would require capturing all of the energy released by every star we can see.
... half of those students [watched at least one lecture], a few hundred thousand completed the course...
These are the only statistic that matters. Who cares how many people sign up and never do anything, maybe they decided it wasn't what they expected. Maybe they don't have the time. But if people are getting something out of it, and some are putting the effort in to complete it, it looks like a success in my book.
A couple hundred thousand course completions? I'd call that a success.
This season, in Australia, we're getting the latest Dr Who episode within 24 hours broadcast on ABC. Plus it's also available on iView. So there's no reason to pirate it.
However, the ABC doesn't run any advertising. So if you do pirate it, does anyone lose money?
A national credit limit of around 40% of GDP should be plenty to cover short to medium term shortfalls and entrepreneur activity. That would include all household, business and government debts. Why have we allowed the banking sector to convince us they are essential for the functioning of every part of the economy? They have a perverse incentive to encourage us to borrow, and over the last 50 years we've bought into their propaganda. Take away all of the interest payments we're currently making and our economy has a chance to thrive.
Where did the majority of your spending money begin its life? Bank loans. Remember that massive issue the banking sector had recently?
We need to get our economy off credit. We need to stop borrowing against every security we can find. Either we reduce our debts voluntarily, or we go bankrupt. Either way, we will reduce our debt level over the next 5-20 years. This is going to remove money from circulation. If the government runs a surplus, this will also remove money from circulation. If we stop deficit spending the economy will shrink and may falter.
Back in the 30's we were facing a similar (but much smaller) debt problem. The "new deal" in 1933(-ish) was a program of government spending that helped to reduce the impact of the Depression. When spending was cut in 1937, the economy dipped again. While the level of debt continued to drop, what finally eliminated the remaining debt was the massive spending and manufacturing to fight WWII.
Government deficit spending isn't the problem. It's the only thing that can save us from ruin as we inevitably reduce our debts.
But the limit is still 70. If they pull you over with a measurement of 80mph, but you take them to court with evidence that your GPS measured 75mph, you're still guilty.
Bored while camping, my family started spear fishing with garden forks in knee deep reeds. Caught about 40 carp, buried them in someone's garden for fertiliser.
I've talked with the developers before at conferences. They were (and probably still are...) using google contacts and messaging for the initial handshake in establishing connections. That may change in future.
They also weren't doing any kind of onion routing. So if they get big enough to be noticed, passive network monitoring may reveal the very social graph that lantern depends on.
“A network of intergenerational transfers makes the typical person a part of an extended family that goes on indefinitely. In this setting, households capitalise the entire array of expected future taxes, and thereby plan effectively with an infinite horizon” Robert Barro
When you actually dig into the assumptions of economic theories like that, they usually turn out to be completely absurd. Of course governments can create wealth. Running a deficit creates both income and money for the rest of the economy.
Banks have the same effect when they issue loans. But they can't do that forever, which is why we're having so much trouble returning the economy to "normal".

Maybe, but that web page seems to equate "speed" with throughput, it doesn't mention latency at all.
Though this would take up more space in the warehouse, would it be faster to unpack each crate / box of items into a vending machine style dispenser?
The actual "picking" of each order could then be automated, with the manual manipulation of products happening in larger batches.

Apparently any new code they write can co-exist with a different license. So they intend to slowly replace it all.
Weird, the minus sign was there, but /. seems to have dropped it, perhaps because it was quoted. Note that I included it when converting to Joules.
