Phase transitions are very real, and they are not just "more space between molecules". Try a high school physics text (hell, dont you learn stuff like "surface tensions" with insects in grade school?)
You just have to develope OSS applications, very carefully.
You have to make it prone to breaking, unintuitive and with a horrible user interface. That way, you can earn money forever by support contracts and paid-for maintainance/seminars/schooling.
The worst you could do would create a "just works" application, because that way you would steal your own future.
I mean, seriously. Anybody remember that incident? Gave valve a golden excuse for delaying HL2.
It happened 6 weeks or so for the announced release data. And magically, after the leak they needed time to fix "security issues". For more than a fucking year. Because we all believe that the game really was finished at that point..
But on my core 2 2.4 Ghz machine, windows boottime more than doubled after encoding the system partition.
Yeah, i can get 100Mbyte/s linear reads and writes. But for some reason, random or semi random access get hosed quite a bit. Maybe it messes with the comand queueing, or the internal prefetch alorithmns, i dont know. Never had a problem on data partitions, but the performance impact on the system drive was enourmous (up to the point that even with 6Gbyte RAM, it wasnt fun anymore)
Ah, and i forgot one thing: the 100Mbyte/s is nearly 100% cpu load on both cores. I dont know where you get 1% overhead from... Even the in-memory benchmark only gets about 150Mbyte under full load on two cores. S
To you mean those particle trails with "impact image"? Just think about the resolution of those trails. Add the 3rd dimension. And then consider that to build this trail, they need the data of ALL sonsors in the volume, to pick out what belongs to the trail.
And then think about his happening 10 million times per second...
They filter out all but a couple 1000 of them, but this still amounts to a lot of data.
And the higgs boson just doesnt appeast in one single image. It might show up in certain types of cascades, or anomalities in other processes, that only become obvious if a huge statiscal base is evaluated.
Yes, there is: Typically, the last few % take a as long as everything before together. Its just that the nature of the chemical reactions involved: During the charge, the battery voltage increases. The charger OTOH cannot push more than 4.2V (for normal batteries) respectively 3.7V for LiFePo4, in order not to damage the cells. This means that effective voltage drops during the charge, and duringe the last bits of capacity, there are only some 0.1V left. Add internal resistance, and its clear why it cannot fill up completely fast
Other comments suggested downrating, but that doesnt really make sense: as long as you leave it in the charger, it will gain charge for a while, so the real capacity is truely higher.
The LHC cooling circuit has something like 400 tons of helium in it. One ton missing sounds reasonable.
The cold doesnt matter, btw. Liquid helium has a really low heat capacity and evaporation enthalpy. A dewar full of liquid nitrogen spilled will do much more damage than 10 times the amount of helium, even if the helium temperature is lower.
And helium is not THAT expensive. At least compared to the other costs.
A physicists analogy is that a LN2 costs as much as cheap beer, while L He as much as good whiskey, per volume... (I once used 2000l of liquid helium in a single week because of a faulty magnet that couldnt be replaced during beamtime. Although that was of course recaptured. I hope they have options to do that in the LHC cave, too, even though the initial containment was breached)
I would expect at least a douzend of failures and faults of that magnitude until full power is reached. Its just too complex. And about the "expensive!!!1" aspect: A few months delay are so much cheaper than spending twice as much before so try to get everything 200% perfect. And even then things might go wrong.
Even in a tiny normal synchrotron, shit happens. At the ALS in Berkelely they managed to detonante a main PSU because they only tested them one at a piece, and when build in they had bad crosstalk. Beam was down for several weeks. At the SLS in Villigen, even months after the full ramp-up beam instabilities or drops happened on rather regular basis.
The used superconductors are good well above 4K (although with decreased maximum saturation). The main point is that they want their helium to be superfluidic, as otherwise it would be impossible to direct the heat over the many km needed (if their were bubble formation in the dewars).
With superfluidic helium, heat resistance also drops nearly to zero(as we are in the real world, it cannot be zero. But heat conductivity increases by many magnitudes, and bubble formation is eliminated). That way, they can keep heat gradients along the whole ring well below 1K.
Thats not true. Its the percentage of the whole solar spectrum, including UV and IR. And its not 10%, but >20% even for moderately priced solar cells (high end is 40%).
Sorry, but if you put big videos (i mean, you want to be better than youtube...) on that webspace, you will be surprised by how quickly you can find out the limits of "unlimited"....
If you cannot see the fundamental difference between a vakuum tube (electrostatic principle) and a solid state device (exploiting of the bandgap, the whole new dimension of doting semiconductors), i cannot help you.
One was a neat invention, the other a revolution that opened a huge new field of solid state physics AND a completely turn the world of technology upside down...
The landsat data alone comes close to 1TB. And that is just the whole world in the broad 30m or so array. (I know, because waaay back, i mirrored part of the Nasa WorldWind data)
This data is in no way fractal in nature.
And just do the math (just to see that your argument is bogus):
A km^2 at level 20 has 4^4=256 times as much data as one at level 16. If you do the math, central europe alone is enough to push the world to an average of level 16 (germany, e.g., is completely covered in airplane pictures, equaling about 25% of the earch surface in level-16 equivalent)

There is no special flaw or exploit in use. They just throw more transitors at a special problem.
Everybody who really want to crack into some network (think NSA or industrial espionage) could have used FPGAs for even bigger gains.
And for joe sixpack, weeks on a small cluster is still not a viable way for free internet...
They use wireless, in the form of cell phone network.
They used scales not becaue of precission, but because weighting was the quickest way to check a large number of devices without disassembly.
To you mean those particle trails with "impact image"?
Just think about the resolution of those trails.
Add the 3rd dimension.

Well, the stats itself sound pretty much like A123 or similar cells: Lithium with an ironphosphate instead of cobalt anode material.
They have higher cycle times, and they can be charged at up to 5C without much problems (which would agree with the 10 min stated).
But they have a drawback: Only about half the energy density compared to normal Lithium Ions.
Not to mention that in order to really charge them that fast, you will need a much higher rated, and thus bigger/heavier PSU brick for the notebook...
Those people are NEVER smart enough to enter an smtp/imap address anyway.

Put a crew module in the cargo area?
The rescue mission doesnt have a payload to fill it anyways...

No it doesnt. Lern at least something about what you are talking about.
Hint: Modern solar cell already absorb 80%+ of all light. thats why they look rather dark...
No it doesnt.
In fact, the way you seem to think solar cells work is beyond retarted.
Hand in your geek credentials and go off to nascar.
Come on. Is EVERYBODY an idiot here?
Thats not true.
Its the percentage of the whole solar spectrum, including UV and IR. And its not 10%, but >20% even for moderately priced solar cells (high end is 40%).
The article is plain bullshit.
Well, of course you could do stuff like that.
In fact, you could use Kdemlia or some other distributed hash system.
The point is that these people want a hierarchical system..
That doesnt change a bit about the fact that mov as a container sucks.
MP4 is hardly better, but at least you dont need to use quicktime for it.
And spare me the "alternatives", i never found them to work reliable.
Sorry, but if you put big videos (i mean, you want to be better than youtube...) on that webspace, you will be surprised by how quickly you can find out the limits of "unlimited"....
Well, reading about your problems makes be glad i am not you. Would suck to be deficient.
