"Extraction of a liter of xenon from the atmosphere requires 220 watt-hours of energy.[52] Worldwide production of xenon in 1998 was estimated at 5,000–7,000 m3"
Sounds like we have some scaling issues before this engine puts us on mars on a regular basis.
Supposing this is true, it took this long because everybody thought that dental X-ray was harmless. (tumor growth in less than 1:4.000.000 images, regardless of the type of tumor.)
Dental X-ray uses less than 0.01 mSv per image.
You absorb 200 times this amount every year, year in, year out. all your life. And if you live in a place with higher background radiation, this number goes up quickly.
So it is hard to prove these tumours are caused by the exams. Lets wait and see what comes out of this.
Usually these kind of studies have some form of bias thats not adequately corrected for.
For me the route was also windows -> linux -> OSX.
However, during my linux period i grew accustomed to finding great software doing almost everything i could wish for within a few clicks/google searches.
For OSX its the opposite. For every small task that i want to accomplish, i seem to need to pony up. Every small time programmer tries to make a buck with his little program. Nothing wrong with that, but where are the Free/Libre alternatives?
For now, after long searches i end up installing untrustworthy programs, because i'm used to get it all for "free" (he, i am Dutch). My problem, sure. But a lot of people like me would fall into these kind of traps.
thats something for the privacy of the home, you pervert.
seriously,
what i meant to imply (and you obviously failed to grasp); Slashdot needs to filter away stuff that is far from impressive. If his mirror had had a diameter of 10m, than that would have been newsworthy for a 19-year old. I'm sure younger kids have achieved more impressive results than sticking some glass chips on a 1m metal plate.
Unfortunately, If you look at the AppDb you'll see a lot of apps still not working 100%. F.i. Graphpad prism disappointed me last week. Most of them don't work because of some minor glitz. Before you say, well fix it you stupid, repairing them would introduce new regressions.
I think its mostly because of some "hacks" used by lazy/clever/performance programmer, but therefore very intolerant to a "windows-like" environment.
I hope Wine will get to the point, where it's influence will force programmers to stick to the specifications, as his/her boss is asking:" but will it also run under Wine???".
Ps. I hope the number of RC's will remain below 40.
1. schizophrenia is right around the corner for everyone, experience it now!
2. Could be great way to cheat on an exam. Teachers will have to walk around with bluetooth sniffing devices (or at random stick fingers into your mouth) to spot this fraud.
3. Also great opportunities for your defence in court:" Sir, mmy wisdom tooth told me to kill him" .
I'll have to agree that simply adding some substance to the air, and having everybody falling sound asleep is a little over simplified.
First of all, chloroform is not that good for your health, there are multiple reasons it is not used for human anesthesiology anymore, but severe organ damage was the most convincing reason.
The russians tried an opiate based drug, and that only proofed that for an adequate sedation, by opiates alone, the dose is so high, that severe respiratoiry depression results. (somehow i feel a 1st year resident anesthesiology could also have told you this).
The rapid onset, non toxic, non voilatile, non respiratoiry depressant and safe for all children and geriatrics drug has yet to be found.
The only thing i can come up with right now is some for of severe hallucinating drug (there are war gasses with these properties). Cant really stand in for the consequences though, after some terrorist with an UZI starts tripping....
I'm sorry to disappoint a lot of diabetics. But the major problem in diabetes is the micro vascular damage. One cannot grow and transplant 10.000 micro vessels in a foot that is about to fall of.
The major gain is in the larger vessels, where no venous graft is available/possible. Now one needs a Gore-Tex graft, but they fail (close) too often too soon.
It will be a long time before i trust this technique to replace my future abdominal aneurysm. The forces there are the true challenge.
What amazes me is that all this investment time and "energy" is spent on cells that produce electricity.
Whereas the collection of Heat is as simple as it can get, but rarely used. Though most mediteranian countries use solar heat for heating their domestic water, but that is about it.
What i have in mind is the use of solar heat, collected during summer, to warm domestic homes during winter. (Thats where real amounts of energy (read CO2) are needed !) Water is an exellent storage container for heat and is dirt cheap.
The only problem is where to store all the warm water. Probably the easiest solution would be to pump up ground water, heat it, and pump it back. (The ground is actually an exellent therman insulator!) Use the 1kW of solar energy from a couple of M2 of these cells to make water run through 100 m2 of cheap solar heat collectors.
It seems to me that a little more competition for RedHat in the server market is a good thing. The stronger (in the form of backing by large compagnies)the competition, the stronger the perception that Linux in the server room is a viable option.
Remember that SuSe is connected to the German goal of designing a groupware server for large work-groups. Seems SuSe is making quite a line-up of products for in the basement of large compagnies.
"Someone should come up with XP-like "hybernate" on Linux. "
ALready exists. Saves the whole shebang in swap, when you boot, it finds it reads it directly into RAM.
patience, it will get mainstream quickly, because the need, as you described, is indeed present.
The previous poster mentioned the Banner been written to disk when surfing. That is actually a browser thing. (saving it for next week when you check in on the site again, not having to download it over 54k again.)
But it made me think;
Is there a viable option to plece between RAM and HD. As the difference between the two is likely to persist for quite a while. I wouldn't mind some solid storage (say 5 gig) as a provider for frequently required data (boot!, office apps, the data your working on at the moment AND your linux/WinXP hybernate file). Should be something of the same size of a traditional HDD, preferably on the same bus (S-ATA??), should not mind thousands of rewrites (sorry for current flashmem) and CHEAP. (same price as a current HDD).
Would be my christmas present (one of them, i'm spoiled)
You would want the source, the compiler AND the settings used to compile the source.
That would give roughly the same binary when you compile it again.
I say roughly, because as fas as i know even the above mentioned variables don't always give exactly the same result. (something like the compiler using system settings for "random" values, or so...??)
Slashdot Mirror
My first thought as well.
Wikipedia's first hit:

Surprised to see noone has opted the easiest solution yet!
Make some random calls to people in Saudi Arabia, Soedan, Ethiopia, etc.
Make sure to mention words like bomb, white house, infidel, plane etc etc.
If some one steals your bike, just call the FBI and ask them where it is.
Sort of the same for me.

5800 mirrors, the size of fingernails. Glued on an already parabolic disc.
Couldn't he just have spray canned it with some reflective paint??
I imagined at least 10x10cm mirrors. Now that would have been "solar power".
wake me up when he heating his house with this. This little satellite disc is kids stuff.
Wasn't another good reason to use salt, that molten salt has excellent thermal conduction properties??
As, you barely have to pump it around, for the heat to reach the reservoir.

Not to mention, the analog reception from the foreign countries is pretty bad.

Wether we (i'm Dutch) are big or small is a matter of perception. But remember, the Dutch own a large part of American real-estate (third largest investor, after Japan and Canada http://www.westplan.nl/nieuws/persberichten/neder
And no, not all analog Tv's will end up in Africa next month. But you will need a digital receiver, tranforming the signal into analog.
So, one can't trademark /copyright the word "RISK", but the poor chap can't "risk" it.
But if we open source it, on a server deeply burried in China...
Make some really poor chap over there sys-admin, with no known adres/phonenumber
Call it "ZIMOR" (Zimor Is NOt Risk ) or something GNU like that....

I'm no expert at this, but how easy is it to have a pipe of molten sodium, insulated from everything, to a tank in the basement.
than have water run by it to heat up the central heating, but never reaching the boiling point.
This all with enough safety, that any moron can have one in the basement?
I think the hot water soultion looks simpler. probably not as efficient, but safer the least.

The future technologies behind the desktop.
One nifty trick with swap is that you can have multiple swaps on multiple disks ( on multiple controllers).
supposed to have a noticable performance benefit.
just add all of them in fstab
Just as in some performance sytems it would probably be desirable to have swap and the massively accessed partion on differend controllers.

Exactly,
I'm also very interested in the ease and ability to repair (or auto-heal) a corrupted file system after a hard crash.
Also, simple undelete would also be on my wish list. just in case.
Anyone here who's got those features ready?

Skimming the links i didn't see anything concerning the range of this technology.
If, as the story indicates, this is to connect pc's range is everything!
But all i see is "common" peripherials nowadays connected by USB to be connected by USB without the wire thingy. (thus: add battery)
Will it make a simple network connection to my friend 6 doors away or not? If not, it doesn't add anything to the things available now.
