Yep now all we need to do is put the sun into a facility where we can harness that incredible energy without spending a metric shitton of money and using up a phenomenal amount of realestate for a minor percentage of efficient energy conversion.
BP has spent in excess of $20bn to aid cleanup, their executive team got axed, their share price is valued below the sum total value of the company's assets and they are still in the process of one lawsuit after another.
Sure sounds like business as usual to me.
I tried that. No end of frustrations. It's supposedly the easiest interface in the world but she simply couldn't figure it out. When dad got his Nexus 7 she stopped playing with her iPad.
My advice to the ask slashdot poster is find someone willing to give up their tablet for a few days as a trial before you commit to something.
Ahhh both worth is not a fixed term.
You can compare that to real money as well. It costs more to create a nickel then what it's worth. The problem is that the nickel is unique in a group of denominations made of other materials with different value so it hasn't affected the currency.
What a more practical example? Let's mine gold.
It costs money and energy to get the gold out of the ground. The end result is that the price of gold will trend in the long run at a value higher than the cost of digging it out of the ground. The same applies to bitcoin. The cost of electricity will anchor the value to ensure mining remains viable in the longrun due to the economic inputs into the system. If electricity goes up, the cost of mining goes up, then either the value of bitcoin goes up or it collapses as a usable currency. I don't see the problem with paying the electricity company in bitcoins. Just like a gold miner gets up in the morning and gets some bread to get a feed. Without the bread he couldn't mine gold, yet with the gold he can pay for the bread. What is the problem?
The problem with your tree analogy is that you forget the other inputs into the system. In one case you're right but just like any project including growing a tree there's a payback period. Sure you'd buy a $500 tree now if you'd instantly get $1000 of value out of it, but what happens if you need to grow that tree, or if the value trickles out slowly? Know why I don't mine bitcoins? Because to break even on my electricity bill I'd need to do ASIC mining and I don't want to spend the money to buy a dedicated miner if by the time I pay it off (2 years or so by last count) the currency may in the meantime collapse. This is also the reason I don't mine gold, I can't afford a decent dragline.
Mining you say? Like actual mining which brings minerals out of the ground and thus gives a currency an economic anchor in value? I think you'll find it's more environmentally friendly to mine bitcoins.
The whole concept of mining helps enforce the scarcity of the currency. The fact electricity costs real money is one of the economic underpinnings of the currency.
For the amount of power it's using you can run an entry level computer with a decent GPU doing some bitcoin mining.
I don't think a few fancy features is the problem here.
No they don't. They require periodic health management. Interestingly enough it's something simple enough to do with a microcontroller, or a tiny single chip solution, both of which draw just a few mA. Even if it were doing continuous monitoring, what is continuous to you? 1 billion times per second? Once per second? A microcontroller waking up once per second can draw in the order of a few microamps. The key is sleeping between readings.
By the way I have a full blown computer here which running flat out uses less than 9W of power. It's industry hardened and has all the bells and whistles.
Maybe Tesla should buy a few of those instead.
What baffles me is why people would install an app named "Brightest Flashlight Free" (name sounds like a moron-magnet)
Because the open source ones aren't as bright. dur.
Not just Google's.
The entire free app ecosystem depends on the sharing of information. If the information is fake the value of it goes down. Bye bye free app.
Somehow I don't have too much of a problem with sharing a bit of info in exchange for something useful.
On the upside in this case slashdot was only 0.000000000001% slower than every other news outlet. Surely this is a new speed record.
FTTN and then enough bandwidth...
Yeah and I stopped reading right there. WiFi is great and all but the sad reality is the technology simply does not have the bandwidth to cover the use case of a densely populated area at any reasonable speed. Hell as it is the infrastructure is crumbling under the weight of a few phones and come 6pm everything goes to shit in most major residential areas.
Same fundamental problem. You're going to need a LOT more nodes for FTTN to be even at all viable with a wireless endpoint, not to mention the cost of infrastructure. You may as well just run a bit more fibre.
And you would rather the state nationalising a private asset? It's amazing how much cheaper you can do things if you don't compensate people for taking something they own.
Sorry which private asset would that be? The one that we built up from our taxes paid for by the people? The one that was then sold to the people again in what can simply be described as double dipping? Speaking of stealing you're not talking about that asset which we built using our dollars, which then was sold to us again, and is now worth less than half as much?
You talk about compensation, how about being compensated the first 3 times. I don't see a problem with nationalising a private asset which was created by the government and should never have been made private to begin with.
Yeah we don't need that fancy power thing either, what's wrong with candles. Telephones? Bah who needs the ability to call for help. Or sewage, it's just a facility for fancy rich folk so they don't throw their waste out the window.
You should learn to never speak in absolutes. Just because you don't see a future for a service doesn't mean it doesn't exist.
Nope only Fluke process meters at our work, precisely because of the voltage rating.
How many components? All you need for USB communication is to get the line levels right (mostly through the use of external resistors and diodes), and have a micro-controller capable of talking at speeds fast enough that the computer doesn't think the device dropped off. USB1.1 is very easy to emulate in software on most microcontrollers 12MHz or greater.
Microcontrollers with hardware USB controllers built into them start at around $2 and have the clamping taken care of so only 2 resistors are needed to get them going. They are also capable of full speed USB2.0 thanks to internal PLLs giving them some phenomenal internal clock rate.
