Linksys apparently cooperates with the kernel guys, but they will not support your linux problems.
And there will be linux problems. Step number one with a linksys card is to throw out whatever ancient driver they ship with, and get the latest drivers from the kernel tree and/or the pcmcia project.
Although including a linux install CD is a nice (if useless for most of us) touch indeed.
Some scholarly communities have been working around the journals for years now, either by making a free, public meta-reference site (high energy physics and astronomy) or by putting things up as e-prints (many fields, at Los Alamos) months before they appear in journals.
It's only a matter of time before other fields catch up. Remember, the web was invented for the purpose of high energy physicists at the CERN and SLAC labs being able to look up citations online, so we've got a ten year head start on, say, historians or economists.
Ok, how would you do go about doing the job of draining out ~40,000 metric tons of water, piecing together 7000 broken 1/2m diameter glass bulbs, and figuring out exactly what happened?
We've had all of three days since it happened. Do you want a quick, random guess, or do you want the right answer?
I'll opt for taking the time to come up with the right answer, thank you very much. Slashdot readers are already doing a pretty good job of supplying the quick, random, uninformed guesses.
Although the most common failure mode is slow leakage, it only takes 1 / 11000 to implode and cause this kind of chain reaction.
A note though - the possibility of a chain reaction implosion has been tested before (we're not idiots), and the tubes came through those tests ok.
So it takes 1/11000 to implode in a particularly forceful way, compared to those tested.
Today's esoteric research is tomorrow's applied science. Let's not short our grandchildren's chances for cool new stuff.
Franklin, Faraday, Maxwell, etc. had weird stuff in their time which later turned out to be rather useful. The same was true for the Curies, Rutherford, and then the whole quantum mechanics crowd in the 1920's.
Where would we be now if at the time people had spent all their research resources on better steam engines instead?
The games are good. The console hardware is good. The cell phones are also a step ahead of the rest of the world.
But, consoles don't run businesses. As such, the whole game playing computer scene is a financial drop in the bucket compared to the stuff which makes banks and factories tick.
Actually, if you buy a Fujitsu workstation or Enterprise class server in Japan, you'll see it's simply a Sun Ultrasparc with the sun logo ripped off and a Fujitsu logo glued on.
So, if you're right, then Fujitsu should market what it's got better and it will rule the World. Or at least the Japanese islands.
In addition to being very clean (and thus with a lot lower background), SNO's primary difference from SK is the heavy water. This stuff provides a lower energy threshold than SK's electron scattering, is sensitive to neutral current interactions, and provides finer energy resolution. That provides different handles on what's happening, and will wonderfully complement the higher energy/higher statistics measurements from SK.
SNO has already shown preliminary results last summer, and will likely publish a detailed paper sometime this year! The whole story will indeed have to wait a few years, though, since nailing down the details of the neutral current vs. charged current measurement involves adding a lot of salt to the heavy water (the better to capture loose neutrons resulting from the interactions).
While high energy collisions provide you with a wealth of information, it's not always the information you need.
Neutrino experiments have indeed measured a lot of good stuff, say from the sun, reactors and accelerators, and cosmic rays.
However, since neutrinos are so hard to measure, these measurements are not nearly as precise as you would like. Compared to the accelerator measurements, they are orders of magnitude less precise! The better nu measurements we make, the better information on how leptons behave the theorists can use in building their models of how everything is put together.
Also, the only neutrinos from stars that have been measured are from the Sun and a few from Supernova 1987A. We would dearly love to see neutrinos from other astrophysical sources, but being far away really kills the signal when the Sun (which is right next door) only gives you a dozen or so nu interactions per day. We need to wait for another nearby supernova (check out our Supernova Early Warning System SNEWS!) or build a Really Big neutrino telescope like AMANDA.
Something like one in ten to the thirty-odd neutrinos will interact.
So, that's enough to see a few of if you if you build a really big detector - Super-Kamiokande in Japan or MINOS in Minnnesota being the experiments I work on.
But, even if you are a fifty-kiloton person and a few neutrinos interact in your chest, that's not enough interactions to pose a danger to you.
Note that this is why these experiments are all deep underground - the cosmic rays bombarding the surface of the earth produce many times more interactions than do the neutrinos. Going underground shields you from a lot of the CR's, so you can actually see the neutrinos.
I used to work with Linux all the time, but now that I work with Solaris I can't say I miss it much. I'd rather spend time adding gcc, bash and friends to a Solaris box than removing Python and stuff from a Red Hat box.
The worst part of this is that even in "upgrade" mode, the install script decides that you really need all the eye candy and gnome foo which you painstakingly un-installed the last time you did an install.
So, you have to go root it all out all over again.
At least the install processes didn't whack nearly as many of my config files as it did the last time. Still, with each release the comparative pain threshold involved in switching to debian instead gets smaller and smaller.
In fact, the Fortify website says that since netscape can now distribute 128-bit enabled browsers themselves, the Fortify people won't bother making patches for versions of netscape past 4.7.
Oh, and netscape's links to the 128-bit versions are somewhat hosed - but I found that hitting a combination of back buttons and "referring page" links when sitting on the error page got me a form to fill out to verify that I wasn't in a scary country. After doing this, things worked properly.
Yes - but for the "phase III" test, where the RH guys were allowed to put in all their latest updates, the end result probobly looked a lot like the soon-to-be released RH6.0.
Also note that their updating produced at best a 14% improvement over the phase II system. So, it would be fair to assume a similar increase in the next round of evolution.
Certainly things would be even better (but good enough to win??) if they'd used 2.3.x kernel SMP stuff - but that's not a fair test, as the systems companies might be using as web servers will seldom be beta.
So you're saying that RH6.1 is a factor of two faster than RH6.0?
Come on.
Sure there is currently a better version of about everything. But, given the time scale upon which linux evolves, there will ALWAYS be new versions of components by the time a place like Mindcraft finishes writing up a detailed white paper about what they did.
If those updates rectify the factor of two the benchmarks see, then bitch for a rematch. Until then, accept reality, and work on making the next version better.
Antares (and the other big under sea/ice neutrino telescopes) have a pretty high energy threshold. They can only see neutrinos which are thousands of times more energetic than those produced by nuclear reactions (like in the sun). Also, these experiments are most sensitive to muon-type neutrinos, and those produced by the sun are electron-type. So, they won't provide much information at all on the solar neutrino puzzle.
The area where the big undersea detectors are hoping to contribute is as neutrino telescopes looking for possible high-energy astrophysical sources of neutrinos, like the supermassive black holes at the centers of many galaxies. These produce large, highly energetic jets of material as they suck in stars and stuff. One side effect of this is that very energetic muon-type neutrinos are also produced. If Antares et al can observe these neutrinos, it will be a great probe of what's going on in the centers of these interesting galaxies.
Actually, the studies of the Sun's vibrations ("helioseismology") have done a really good job of confirming that the sun is indeed put together the way astrophysicists have always claimed. Thus, the sun is indeed fusing properly.
This evidence supports the proposals that the deficit of observed neutrinos from the sun has to do with something weird happening to the neutrinos themselves rather than something weird happening to the sun.
I generally have a more open mind towards people who understand simple spherical trigonometry. We on Super-K use cos-theta to keep equal solid angle bins, and these jokers think it's because we're hiding something. Whee.
Would you put your pregnant wife on a 747 from NY to LA?
Let your kids play in the basement very much? Even if you don't have a basement, I'm sure that you let doctors use X-rays on them.
Radiation is not something horrible thing evil mad scientists and the military industrial complex inflict upon the world. It's a fact of life. Mother Nature is loaded with the stuff. Take all the radiation in Cassini's RTG's and spread it out, you don't have to spread it very far to make it reach the same level as the natural background. If, however, you don't spread it out very far, then it's that much easier to contain and clean up.
What people are saying here isn't "techo-macho insanity". It's a realization that while everything has some risk, just because some microscopic risk is mentioned in the same breath as Horrible Evil Radiation isn't call to abandon all your rationality. People who don't know a Neutron from a Neutrino from their own Nuts are the most likely to get all worked up over such nothings.
Oh wait. I forgot. The reason that most all the people who actually know something about radiation and nuclear science aren't the ones who are freaking out is because we're all Evil Mad Scientists and part of the aforementioned Military Industrial Complex.
Fear of the Unknown. Had they lived 200 years ago, the same people who were picketing Cassini's launch would have been first in line to burn the neighborhood weird old lady as a witch when the village's cows got sick.

Two things -
1) Browsing the rest of the threads here, you're in good company. "Galileo was right and persecuted, so therefore all people who are persecuted are right".
2) The way the scientific method _works_ is for there to be conflict between old ideas and new. In a Darwinian sort of processes, the bad new ideas get discarded, and the good new ideas replace the old, less good ideas.
CF was a really attractive idea. In the form it was proposed, it was proven wrong with far more certainty than most new ideas, simply because if it worked, the rewards would be enormous, so everybody took a look at it.
I'm not saying people shouldn't be interested in understanding weird electrochemical reactions. But journalists invoking government conspiracies or the ghost of Galileo to cover their own ignorance is pretty annoying.
(bleh - cookie got munged, wasn't logged in, so trying again so as not to be an AC).
> No. The experiment *was* not repeated. What's > the difference between that and *could* not be > repeated?
Really? The fact that after the announcement, everyone and their dog _tried_ to repeat it, and failed miserably, speaks for itself.
Oh wait - the elite DoE gremlin teams were simply really busy sneaking into every physics department across the world (not just in the US, for you Americentric conspiracy buffs) carefully sabatoging all the experiments. Yeah, that's the ticket.
Getting something for nothing is harder than it looks. Cold Fusion is the physics equivalent of MMF spam, only people are more ready to believe that our wonderfully incompetant government is actually a real whiz when it comes to complicated conspiracies.

Willfull disregard for the law is hardly a good resume bullet for someone who wants to be the guy in charge of the country's laws. Stack this up with all the other "little" laws the guy's broken. Not the picture of someone I'd want to trust with our country's console.
> I guess that 8 processor system I got running RH 5.2 on last week didn't count in the study.
Nope, it doesn't. Get it running on 64 or 256 processors with true shared memory and then it might. Beowulf doesn't count either, that's not SMP it's clustering of independant machines.
Linux is cool. It rocks the medium-low end of the computer world and nukes NT. But, it can't touch the high end stuff - yet.
> Why would Microsoft publicise the risks of using its over elaborate technology?
Sadly enough, exactly one of the many mainstream press stories I saw/heard on the subject even mentioned MS at all (one of two NPR bits).
If all your information came from the mainstream press, not only would you not know that it's MS's fault, but you wouldn't know what the vulnerable setup was so you could take precautions.
And face it, unless you happen to be interested in Random Topic X, all your information about Random Topic X comes from the mainstream press. Given that I cringe every time I encounter a news story about something I've got a small clue on, shouldn't I worry about believing them about things I don't know anything about? You bet!
