ARM is going to be a significant part of future server space. This issue comes up every so often on Slashdot and I always see the same reaction: x86 is the one true architecture and nothing will displace it. That's not a technically based opinion, it's a religious dogma.
When you're on the client side of the network, it makes no difference what's on the server side. It could be a giant room full of hamsters and abacus. As long as the results come back fast and correct, you shouldn't care. That's the way the internet was designed. Heck, that's why it'd called the Inter-Net. Inter networking between different processor platforms.
Intel is a one trick pony. Besides the evolution of the x86, they have never fielding an architecture that had any staying power. Anyone remember the i432 or the i860? The current standard x86-64 architecture was defined by AMD, not Intel. Itanium got that moniker because it was accurate. The only reason that the Itanium is alive is because of a civil suit by HP.
What Intel is really really good at is putting gates on silicon. They did not succeed on architectural grounds, but by having the best implementation of a clunky architecture. They were always able to succeed by using more gates at a lower price then the competition.
ARM is an architectural rival to x86. Intel won with the x86 because they could cram more gates onto silicon. They loose this advantage against ARM because ARM requires less silicon to do the same job. This translates to lower power usage, which is getting more and more important as time goes on. Other foundries can compete even if they are trailing Intel in processes capabilities, and they want to be in this market. As does AMD.
ARM also benefits from being the dominant architecture for the smart phone/tablet sector, which means that there is a large community of developers and all the software one could ever want. An ARM-centric ecology exists, and it applies to servers as well as client software. Linux/GCC/MySql are happy on ARM, so any open source server software is easily available. And Microsoft has shown they are ready to run on ARM as well. It's not a risk from a software point of view.
It's not that Intel/AMD x86 is going away, but ARM will also be a player. And we should all be glad about it, because AMD being less competitive with Intel is the road to monopoly, which means increased prices and a stagnant CPU sector.
However, about 15.5 seconds into the flight the upper right-hand fin unlocked and deployed while the booster was still firing....
Indications are that the fin deployed because a random vibration issue caused the assembly to vibrate harmonically while in boost phase, so that the actuator responded and sprang open.... Brink says that the simplest fix will be to deploy the fins on the cruiser about one or two seconds after being dropped from the B-52 instead of later when the vibration problem occurred so that the fins are powered up and protected from damage.
You're assertion is that the problem is the same as tightening the lug nuts on a car tire. The only lug nuts I see are the ones rattling around in your empty skull.
This aircraft needs to achieve almost Mach 5 before the engine even starts, so it requires an air drop and a rocket booster even to start working. It operates in a test domain that cannot be completely simulated or created in a ground test. This is exactly the kind of failure that can only be encountered by a live lest. You have to build it, fly it, and see if it breaks. There is no other way.
Given you complete lack of technical understanding, I would suggest that you stop wasting people's time on Slashdot and go somewhere more suited to your mental level. I hear that Disney has a lot of nice stuff for children. I think you would fit right in.
Taking a quick glance at the replies, Slashdot is truly the wrong place to ask this questions. It's like asking a bunch of raging drunks how to stop drinking. All that happens is that they offer you another drink.
Having said that, there are a few useful responses amid all the defensive knee jerk reactions. Recognizing you want to move beyond your current nerd limited comfort zone is the most important step, as others have already said.
Women generally have much better social skills then men, particularly men who are technically oriented. If you seek out situations where you interact with more women you will have the opportunity to better your social skills. This will help counteract the arrogance that you are worried about.
I'm not talking about dating here, I'm talking about being in situations where you are interact with the opposite sex as an intrinsic part of whatever activity is going on. Dating might be a consequence, but it should not be the sole reason you are there. (I can already imaging the kind of response this is going to elicit here, but that's another issue.)
Since you are in school, I would suggest taking some courses in the humanities, specifically music, literature or art. These courses are likely to have a less one sided gender ratio and they also have the benefit of expanding the kinds of thing you can talk about. Studio classes, where you actually do art, are good because you are expected to talk about what you are working on.
Remember, asking for help, or offering to help someone is always a good way to interact. Generally women are better at men at this, so admitting to a woman that you need assistance will often get a useful response.
And take some cooking lessons, or find a cooking class on or off campus. It's a skill that everyone should have, and people who cook love to talk about their favorite recipes.
Good luck. You are already on the right path by realizing that there's more to life then being a nerd.
This is just the first few listed. There are lots more. Some months there are over a dozen.
Yep, the drug business is really low tech. You just go into the woods and find an old lady in a run down hovel and she mixes you up a potion out of things she's collected in the forest. Don't forget the magic words that you have to say.
Whoever is stupid enough to make this a topic on Slashdot: this is a right wing troll. The big bad evil government is not going to rip your high end gaming machine from your cold dead hands. Stop wasting our bandwidth and time with this dumb ass crap.
I think this is deliberate counter propaganda that shows up more often when there is some big scandal about business doing something stupid that screws a lot of people. In this case I guess it is the compounding pharmacy that caused the meningitis epidemic. The corrupt criminal organization calling itself the "International Academy of Compounding Pharmacists" successfully lobbied Congress to defeat attempts to regulate their industry. Now there are over 200 meningitis cases and 15 deaths, and the number of exposed patients may be higher because more drugs were tainted.
If you want to be paranoid about something, worry about corrupt politically connected businesses risking your life for profit. It actually happens. Not that it often ends up on Slashdot, as opposed to right wing scare tactics.
I suggest that you go see the upcoming film Atlas Shrugged. It also features the government as the big bad boogieman who is going to take away all your shiny toys. And it's being released just in time for Halloween, so all the libertarian weenies can sit around the camp fire and tell scary stories about how the black helicopters are going to come and take away all the guns and penises.
Meanwhile, over here in the real world, 14000 people are at risk of fungal meningitis, 186 have been diagnosed, and 14 or more people have died. Those who contract the disease and recover can suffer permanent damage. According to WebMD http://www.webmd.com/pain-management/news/20121012/fungal-meningitis-qa?page=3
Some people will make a full recovery, but others can expect long-term damage from the infection or the drugs used to treat it.
“The recovery is long,” Schaffner says. “These fungi actually destroy tissue, and that tissue will eventually heal, but can’t restore itself, so some patients will be left with disabilities.”
In addition, prolonged use of the antifungal drugs can damage the kidneys.
Strokes caused by the fungal infection may also cause lasting mental and physical problems.
This could all have been avoided, but the freedom loving drug industry was able to avoid all the needless bureaucracy and expense involved in testing and adhering to safety standards. Who cares about risk when we're making good money here?
So let's just drum up some fake outrage about the evil government, and pretend this whole bad drug thing didn't happen.
(I have two friends who have gotten injections of these drugs for chronic back problems, and they both gratefully reported that they had not had this procedure in over a year. Now if we could just take all the recalled vials and dispose of the drugs by injecting libertarians then we could solved two problems at once.)
Yep, you're obviously correct. Everyone at NASA is stupid, and just by looking at a summery on Slashdot you have reached a conclusion that escaped them. Windows or plain old Linux would work just fine.
If your comment is any indication of you native intelligence I don't know how you manage to put your clothes on by yourself. It's surprising that you haven't wandered into the street and been killed by a car. (That's just my wishful thinking, by the way.)
Any autonomous vehicle, is by definition, a real time system. It's working in a physical environment that requires hard real time response. If the control action is not delivered in a specified interval, it is useless. The result of missing a hard deadline is crashing. Not such a good idea on Mars. The speed of light delay time is 14 minutes one way, and it's going to get longer since the Earth and Mars are now moving apart.
All indications imply that you are as stupid as you look. Your SIG implies that you are a knee jerk right wing asshole, who assumes that all government activity is useless. I worked a JPL years ago, and everyone one I met there was bright, creative and dedicated. There were no slackers. I doubt you would last in that environment for two pay periods. You're not smart enough.
How come you're posting in English, rather then Esperanto or Loglan? Remember, all natural human language is based on "the crap someone could find in their near vicinity"?
After Arkansas Republicans disavowed a book by state representative Jon Hubbard (R-AR) claiming slavery was “a blessing in disguise” for African Americans, Hubbard’s colleague, state Rep. Loy Mauch (R-AR) has been outed by the Arkansas Times for his pro-slavery, pro-Confederacy letters to the editor over the past decade. Mauch’s run for reelection this year is backed by the Arkansas Republican Party.
In letters to the Democrat-Gazette, Mauch vehemently defended slavery and repeatedly suggested Jesus condoned it:
If slavery were so God-awful, why didn’t Jesus or Paul condemn it, why was it in the Constitution and why wasn’t there a war before 1861?
The South has always stood by the Constitution and limited government. When one attacks the Confederate Battle Flag, he is certainly denouncing these principles of government as well as Christianity.
So when I get modded down to Troll, it proves that I am right. The Republican Party is a reactionary movement that is intent on eliminating liberty and disenfranchising much of the population. The position of this inbred loony and Justice Scalia are only slightly different.
These are not mutually exclusive effects. One could argue that the "wealth" extracted from the stock market by algorithmic trading/casino capitalism is effectively draining real wealth from the small investors (suckers). The end point of this process is a investment environment where the insiders have so much capital that the illusion of a functioning investment environment collapses. Anyone else attempting to invest will only have access to the equivalent of penny stocks.
If you look at the investment career of the plutocratic candidate Romney you can see how far this transformation has already gone. A lot of his $250 Billion (or more) was acquired (i.e. stolen) from Bane investors. The deals were always structured so that Bain insiders would come out ahead, no matter what the outcome: win, loose or draw.
What is called capitalism in the West is close to the way the Mafia used to work after WWII. You joint a crew associated with an insider and you get a license to steal. You pay for the privilege of stealing by kicking money to the bosses. In the current setup the insiders support outfits like the American Enterprise Institute and the Chamber of Commerce which influence government to legalize theft.
A current example: Wallmart is in huge scandal right now with bribery in Mexico.
It came to light that after paying the bribes WalMart’s leadership team did about everything it could to cover them up. Including spending millions on lobbying efforts to hopefully change the laws before anyone was caught, and possibly prosecuted. The goal was to keep the stores open, and open more. If that meant a little bribing went on, then it was best to not let people know. And instead of saying what WalMart did was wrong, change the rules so it doesn’t look like it was wrong.
The US Chamber of Commerce was the vehicle for their attempt to change the law to make bribery legal.
The push to revisit how federal authorities enforce the statute has been centered at a little-known but well-funded arm of the U.S. Chamber of Commerce where a top executive of Wal-Mart has sat on the board of directors for nearly a decade.
The effort has intensified in the past two years, drawing on the backing of several large companies and trade groups such as the Retail Industry Leaders Association, where one of Wal-Mart’s top executives serves as a director. It also has involved high-powered lobbyists, including former attorney general Michael B. Mukasey.
There is no evidence that suggests Wal-Mart participated in the Chamber’s efforts because of its problems in Mexico. (Emphasis added.)
If you believe that last line you also should believe in the tooth fairy.
It's not the Supreme Court of the United States, it's the Supreme Court of the Republican Party. Specifically the far right Republicans. If you have any doubts, just remember how Bush was appointed President in his first term.
None of this is off the record. It's all been reported. The news media has a combination of self censorship and ignoring the "boring" stuff. This is why it's never reported, and why this is a big surprise on Slashdot.
Justice Antonin Scalia has already called questions about the death penalty "laughable," saying if it was a law when the country was founded, then it's a law now.
And now the "originalist" is attacking homosexual behavior in the same breath as abortion and opposition to the death penalty.
During a speech at the American Enterprise Institute, Scalia said he disagrees with colleagues who now believe the death penalty is unconstitutional, the AP reported.
He then seemed to suggest that he didn't think homosexual activity was protected by the Constitution, either.
"The death penalty? Give me a break. It's easy... Homosexual sodomy? Come on. For 200 years, it was criminal in every state," Scalia said.
To quote the friend who sent this to me:
When the country was founded slavery was legal, adult women were
legally and socially considered minors and one step above chattel,
child labor was legal, "buggery" was punished by death, indentured
servitude was legal, conscription into the armed forces was legal,
genocide against Native Americans was legal (and enthusiastically
pursued), and I could go on and on.
So how do you think Scalia will vote? The accepted current rights of the consumer, or some radical approach that will put more money and power in the hands of corrupt business interests? If you take him at his word, he would be happy to re-instate indentured servitude. What were the state of consumer rights 200 years ago? Still want to make a bet?
He claims to be an "originalist", but in fact his is a extreme radical. He's proud of this position, and makes speeches link this all the time. And it rarely makes the main stream headlines.
I expect that all the righty trolls will be making excuses for Scalia and the American Enterprise Institute. His idea of freedom, and the AEI idea of freedom, is that you STFU and do what your masters tell to to do. How bad does it have to get so that even the Slashdot nerds wake up and realize that the right wing want to turn them into peasants?
When I talk critically about the Russians smuggling and not stealing IP on line I am being sarcastic, that is conveying contempt for both Russia and the USA.
When i praise the Chinese for their efficient on line spying I am being ironic, saying the opposite of what I really feel.
When I talk about a lack of Federal policy on protecting US assets from cyber attacks, I am being accurate. There is no enforceable federal policy about protecting infrastructure or intellectual property on line. There are a lot of rules about ITAR and security for military programs, but nothing in the civilian sector.
When you talk about commercial heavy equipment that has no export controls, you are being obtuse. This shows a lack of intelligence on your part.
It doesn't conform to the TSA paradigm, so they will reject it.
1. It is not intrusive enough.
2. It replaces sullen TSA uniformed personal with hardware.
3. It reduces the DHS conditioning intended to make the general public accept arbitrary behavior by the government.
4. It is not as dangerous as full body radiation from scanners.
There are a few things that might make the TSA like it.
1. It is really expensive.
2. It doesn't actually work.
3. It will interfere with people for no discernible reason.
On the whole, it's reducing the number and visible presence of the TSA uniformed types that will keep it from being adopted. They are already so expensive, intrusive, arbitrary, and incompetent that they don't need that level of automation.
Don't they realize that all "US" electronics are made in China? Why are the going through all the trouble to illegally export gear from the US when they can get it directly from the manufacturers in Asia? They are still stuck in a Cold War mind set, where the US is the enemy and Asia is not the major source for technology. They need to stop living in the past.
Nothing is actually made in the US any more. The big bucks here are in intellectual property and patent litigation: Samsung vs Apple.
The Chinese are ahead of the curve on this. They know the best way to gain advantage is to use cyber-theft to steal IP. It is very cost effective and produces quick results.
Unlike export controls, there is no national policy on protecting IP online. Every time someone in the government (Democrats mostly) brings it up business interests scream about government interference, needless regulations and creeping bureaucracy.
If something is stolen via cyber-theft, their is no legal consequence. Even in the military sector, none of the big defense contractors ever are fined or loose contracts because they leak classified information like a sieve.
Heck, now with the complete lack of controls on campaign contributions it would be cheap to insure that the current online vulnerabilities remain the norm. All you have to do is give some money to the right elected officials in Congress, and stealing US technology will remain as easy as taking candy from a baby.
The Russians need to get with the program and copy what the Chinese are already doing. They should be spending more money on PACs, and stop wasting effort on smuggling.
If you want to understand the DHS, all you have to do is change the name: Department of Homeland Pork. When you follow their activity, just think DHP instead of DHS, and it all becomes perfectly clear.
The DHP has two missions. The primary mission is to expand the budget of the DHP. The secondary mission is to intrude into every aspect of peoples lives. Mission two is a way to justify mission one. So far they have a 100% success rate. Note that security is not even on the list.
Thank you very much for the informative response. I did not intend to dismiss the simulation results, I just wanted to get a better understanding of what they did or did not imply. Viewing the results as a consistency check provides a useful context.
I know that the experimenters would like to be able to explore the limits of the current modeling techniques. These simulations are so time consuming that running examples that are expected to fail (not match known observational data) is hard to justify. Hopefully decreasing computing costs and software improvements will allow cosmologists the latitude to do these kinds of tests as well.
Slashdot tends to produce more heat (and dumb jokes) then light, so it is really nice to have an interaction that is so informative. Thanks again for providing such a thoughtful answer.
This is clearly good work, but I believe that the article glosses over real problems with these kinds of simulations. The short version of the problem is that the agreement between the model and the observations doesn't provide a huge degree of confidence in the model being tested. It appears that both the model and the starting setup are per-disposed to produce results that match observations.
There has been no perturbation testing of the model. It does not seem that they did any runs that were intended to produce a result that did not match observations. They have no idea what range of input or modeling change produce a result that matches observations.
The greatest utility of these simulations is when they don't match observations. This opens the possibility that the current ideas are incorrect, and that new ideas are needed.
I also wonder about scaling issues. The three simulations at different scales are unconnected. There is no way to see how events at one scale effect events at other scales.
The author also said one specific thing that bothered me:
Astrophysicists can model the growth of density fluctuations at these early times easily enough using simple linear equations to approximate the relevant gravitational effects.
I am not a physicist or cosmologist, but that seems to be a huge assumption. We have no idea what dark energy or dark matter are, but they can be modeled by "simple linear equations."
I know that the shear cost and complexity of these computational experiments means that they are hard to accomplish. Even so, I will be less skeptical about their value when they are done in ways that test how the simulations fail, as well as how they verify current ideas.
In other news, leaked reports claim that Assange is not an Australian. He was actually born in Kenya, was raised as an Islamic communist fascist agnostic atheist, and was schooled in a madras where he was inducted into a coven and engaged in human sacrifice.
It is also claimed that he is adept at voodoo and has his own personal zombie army. Sources indicate that his zombie forces are closely allied with organized werewolf and vampire cadres who are planning a global coup intended to bring the Apocalypse, institute the rule of Satan on earth, and overthrow heaven.
What kinds of phenomena are astronomers expecting to see as a result of this event? Specifically, I'm wondering about the matter falling from the proto-planetary disk into the black hole gravity well. What will it reveal about black hole features? Will be able to get more precise information about the mass, rotation and magnetic field? Will it be possible to test/verify predictions of relativity or string theory? I am under the impression that there are gaps in the understanding of how the axial jets form when matter falls into a black hole. Will we detect jets, or is more mass needed?
What passes for capitalism in the US is a collection of cartels. Each sector of the economy is dominated by a small set of entrenched insiders. They compete among themselves, but only to dominate the sector and reap larger profits. The competition always has a negative impact on consumers.
To take a current example, look at Samsung vs. Apple. No matter who wins, users loose. Where Apple is winning they are trying to eliminate Samsung, and vice versa. Whoever wins, your costs will be artificially high, and your service will suck.
The banking industry is the same way. So is agribusiness. At the consumer level supermarkets have razor thin profit margins, but the big players in food production also form a corrupt insiders club: Monsanto, Cargill, Archer-Daniels-Midland. Individual farmers are not agribusiness insiders, they are another group of victims.
This is capitalism in name only. It does not produce the benefits for society that is the claimed rational for a capitalist economy. As a consumer you have no meaningful choices because all the vendors are corrupt and inefficient. It's organized theft at a global scale.

If you believe that last line you also should believe in the tooth fairy.
None of this is off the record. It's all been reported. The news media has a combination of self censorship and ignoring the "boring" stuff. This is why it's never reported, and why this is a big surprise on Slashdot.
Here is what Scalia just said to the American Enterprise Institute on Oct. 5th, just last week. http://www.businessinsider.com/scalia-says-homosexual-sodomy-was-criminal-2012-10 Oct 5, 2012
To quote the friend who sent this to me:
So how do you think Scalia will vote? The accepted current rights of the consumer, or some radical approach that will put more money and power in the hands of corrupt business interests? If you take him at his word, he would be happy to re-instate indentured servitude. What were the state of consumer rights 200 years ago? Still want to make a bet?
He claims to be an "originalist", but in fact his is a extreme radical. He's proud of this position, and makes speeches link this all the time. And it rarely makes the main stream headlines.
I expect that all the righty trolls will be making excuses for Scalia and the American Enterprise Institute. His idea of freedom, and the AEI idea of freedom, is that you STFU and do what your masters tell to to do. How bad does it have to get so that even the Slashdot nerds wake up and realize that the right wing want to turn them into peasants?
Who are they going after in their simulated attack?
When i praise the Chinese for their efficient on line spying I am being ironic, saying the opposite of what I really feel.
When I talk about a lack of Federal policy on protecting US assets from cyber attacks, I am being accurate. There is no enforceable federal policy about protecting infrastructure or intellectual property on line. There are a lot of rules about ITAR and security for military programs, but nothing in the civilian sector.
When you talk about commercial heavy equipment that has no export controls, you are being obtuse. This shows a lack of intelligence on your part.
I hope that clears things up for you.
1. It is not intrusive enough.
2. It replaces sullen TSA uniformed personal with hardware.
3. It reduces the DHS conditioning intended to make the general public accept arbitrary behavior by the government.
4. It is not as dangerous as full body radiation from scanners.
There are a few things that might make the TSA like it.
1. It is really expensive.
2. It doesn't actually work.
3. It will interfere with people for no discernible reason.
On the whole, it's reducing the number and visible presence of the TSA uniformed types that will keep it from being adopted. They are already so expensive, intrusive, arbitrary, and incompetent that they don't need that level of automation.
Nothing is actually made in the US any more. The big bucks here are in intellectual property and patent litigation: Samsung vs Apple.
The Chinese are ahead of the curve on this. They know the best way to gain advantage is to use cyber-theft to steal IP. It is very cost effective and produces quick results.
Unlike export controls, there is no national policy on protecting IP online. Every time someone in the government (Democrats mostly) brings it up business interests scream about government interference, needless regulations and creeping bureaucracy.
If something is stolen via cyber-theft, their is no legal consequence. Even in the military sector, none of the big defense contractors ever are fined or loose contracts because they leak classified information like a sieve.
Heck, now with the complete lack of controls on campaign contributions it would be cheap to insure that the current online vulnerabilities remain the norm. All you have to do is give some money to the right elected officials in Congress, and stealing US technology will remain as easy as taking candy from a baby.
The Russians need to get with the program and copy what the Chinese are already doing. They should be spending more money on PACs, and stop wasting effort on smuggling.
The DHP has two missions. The primary mission is to expand the budget of the DHP. The secondary mission is to intrude into every aspect of peoples lives. Mission two is a way to justify mission one. So far they have a 100% success rate. Note that security is not even on the list.
I know that the experimenters would like to be able to explore the limits of the current modeling techniques. These simulations are so time consuming that running examples that are expected to fail (not match known observational data) is hard to justify. Hopefully decreasing computing costs and software improvements will allow cosmologists the latitude to do these kinds of tests as well.
Slashdot tends to produce more heat (and dumb jokes) then light, so it is really nice to have an interaction that is so informative. Thanks again for providing such a thoughtful answer.
There has been no perturbation testing of the model. It does not seem that they did any runs that were intended to produce a result that did not match observations. They have no idea what range of input or modeling change produce a result that matches observations.
The greatest utility of these simulations is when they don't match observations. This opens the possibility that the current ideas are incorrect, and that new ideas are needed.
I also wonder about scaling issues. The three simulations at different scales are unconnected. There is no way to see how events at one scale effect events at other scales.
The author also said one specific thing that bothered me:
I am not a physicist or cosmologist, but that seems to be a huge assumption. We have no idea what dark energy or dark matter are, but they can be modeled by "simple linear equations."
I know that the shear cost and complexity of these computational experiments means that they are hard to accomplish. Even so, I will be less skeptical about their value when they are done in ways that test how the simulations fail, as well as how they verify current ideas.

It is also claimed that he is adept at voodoo and has his own personal zombie army. Sources indicate that his zombie forces are closely allied with organized werewolf and vampire cadres who are planning a global coup intended to bring the Apocalypse, institute the rule of Satan on earth, and overthrow heaven.
Plus, his mother dresses him funny.
Inquiring minds want to know.
To take a current example, look at Samsung vs. Apple. No matter who wins, users loose. Where Apple is winning they are trying to eliminate Samsung, and vice versa. Whoever wins, your costs will be artificially high, and your service will suck.
The banking industry is the same way. So is agribusiness. At the consumer level supermarkets have razor thin profit margins, but the big players in food production also form a corrupt insiders club: Monsanto, Cargill, Archer-Daniels-Midland. Individual farmers are not agribusiness insiders, they are another group of victims.
This is capitalism in name only. It does not produce the benefits for society that is the claimed rational for a capitalist economy. As a consumer you have no meaningful choices because all the vendors are corrupt and inefficient. It's organized theft at a global scale.
