Seriously:

I have a couple dual-core PCs. I notice that some won't ever use 100% CPU even though they easily could. I check "set affinity" in task manager, which says the process should use both cores...but it only ever hits 50% of total CPU. Looking at the CPU graph, it shows that as usage goes up on one core, usage goes down on the other.

Is there any way to force a process to run over 2 cores at 100%?

If not...how would 300,000 cores help unless you are running 300,000 processes, or an app that you know will scale over that many cores?

The preceding was in fact a serious question.

If your process looks like this:

int main()
{

while (something)
{
      doSometing();
}

}

It will hit 100% on one core and that's it. Its not multithreaded - one CPU will churn on it forever and the others will sit around waiting for a task from the OS. 2 course, 200,000 cores the results will be the same. These machines are made for tasks that are broken up into lots of smaller jobs and processed individually. Its not magic - more cores won't get a single threaded process done faster.

Seriously.

  Rambus sues Nvidia for patent infringement[->] 2008-07-11 10:30 aurispector

Submitted by aurispector on Friday July 11, @10:30AM
aurispector writes "Well, they're at it again: Cnet is reporting that Rambus is suing Nvidia, accusing the company of violating 17 Rambus-held patents on memory controllers. The suit was filed Thursday in the U.S. District Court for the Northern District of California. The Los Altos, Calif.-based company says that chipsets, graphics processers, and media communication processors across six different Nvidia product lines are illegally infringing. The patents held concern memory controllers for SDR, DDR, DDR2, DDR3, GDDR, and GDDR3 SDRAM. Does this action officially confirm that Rambus is a patent-troll rather than a technology company?"

Is his identity for sale? Otherwise all he is selling is a bunch of stuff. Not "His Life". It would be more interesting if you could actually buy his identity and completely assume his life. Of course, you couldn't do that completely. His friends probably aren't going to buy into it. And also, what of the government?

If he can't tell everyone the reason why his wife left him, then he is obviously not ready to give his life away. He is still holding on to the idea of privacy, when in fact he is giving that away. Could you imagine selling all the pictures, memorabilia, etc. that you have.

Nah, they won't.

I live in the area, and let me tell you, people would rather KNOW they are going to have a paycheck, at least in theory because of seniority if nothing else, than NOT because they jumped ship to get a 20K a year raise.

Not when you paid nearly a million dollars for your 3 bedroom house.

There ARE people within a few miles of my house paying 25 thousand dollars a month in RENT.... My neighborhood is in the 2 to 3K a month range, and if I KNEW I could pay my bills with the economy going to the toilet, there is NO good reason for me to jump ship for a raise.

Three years ago, they ALL would have jumped ship. It's a different type of world now, since foreclosures, etc. are looming everywhere. Local trash mags have foreclosure sales listed, as do newspapers.

Apple should pony up some of those profits, but a smart board and CFO would realize, they might need a bit of cheese to get them through the thin period we can all see coming.

YES! They probably are mostly zealots and fanboys otherwise they'd be working for M$. Pretty much anyone with an Apple becomes a zealboy so they have about 5% of the computing audience to hire from and most of them don't know they're being shafted, they're just working a dream job for the company that made the friendly overpriced computer they love.


I know you're being sarcastic, but that does touch a subject that I've genuinely wondered about.

See most stories we're graced with from Apple (which isn't to say it's a comprehensive set, but just that that's the image that Apple itself is perfectly happy to give) is that everything happened because of the Great Man Steve Jobs, and (thinly veiled) in spite of those lazy incompetent engineers. X is all due to the Great Man's vision. Y was personally tested by the Great Man. Z only happened because the Great Man yelled at the engineers and told them to make the things He wants. W happened because, frighteningly enough, the Great Man didn't yell for a change, but just fixed the engineers with his iciest stare and asked them when are they going to get it done. Etc.

Frankly, it gives the impression of something more like Stalin's USSR or Mao's China than anything even vaguely resembling a company or a boss I'd like to work for. Not saying that it's necessarily that bad, I wouldn't know, but that's the impression that Apple's propaganda machine leaves. Seen from outside, and if the question came, "well, would I want to quit my job and try to get a job there?", it doesn't exactly sound motivational, to say the least.

Even skipping past the other implications, I never heard the Great Man giving credit to anyone else but himself. You hear all the time about how the iPod's success is because Steve Jobs himself said how loud the volume button should go, but you never hear who was actually the guy who designed the bloody thing. Well, not from Apple. It's not hard to dig up the names, but I'd like just once to hear Apple just come out and say "we'd like to thank these guys for making it possible."

Even from MS, for all its other sins, you hear about who championed, say, their getting into the whole Internet thing, against Bill Gates's vision. Or about those two guys whose bright idea was to make DirectX instead of just going with the OpenGL flow. Heck, you even hear about the Bob clusterfuck being the brain child of Melinda Gates. Good or bad, it's not particularly hard to find out who was really behind what.

I'm not saying that Bill Gates is a nice guy, and Ballmer probably even less so. But between one narcissistic bully who at least gives credit, and a narcissistic bully who doesn't, Bill comes out as a bit less of a low life on my scale.

Frankly, just about the only positive thing I hear about Apple as an employer, is that they don't discriminate against anyone. Their world is so centered around the cult of Steve Jobs, that there is no room for caring whether you're black, gay or whatever else. You're the worthless peon, and that's enough about you already.

Now I hear that the wages aren't that great either.

So, really, please help me understand. Why _do_ those guys go work there? I'm genuinely curious.

vsync64 writes "Last night, Congressman Dennis Kucinich (D-OH) spent 4 hours reading into the Congressional Record 35 articles of impeachment against George W. Bush. Interestingly, those articles (63-page PDF via Coral CDN) include not just complaints about signing statements and the war in Iraq, but also charges that the President "Sp[ied] on American Citizens, Without a Court-Ordered Warrant, in Violation of the Law and the Fourth Amendment,' 'Direct[ed] Telecommunications Companies to Create an Illegal and Unconstitutional Database of the Private Telephone Numbers and Emails of American Citizens,' and 'Tamper[ed] with Free and Fair Elections.' These are issues near and dear to the hearts of many here, so it's worth discussing. What little mainstream media coverage there is tends to be brief (USA Today, CBS News, UPI, AP, Reuters)." The (Democratic) House leadership has said that the idea of impeachment is "off the table." The Judiciary Committee has not acted on articles of impeachment against Vice President Cheney introduced by Kucinich a year ago.

Disney land is in the LA Metro area which has a population of about 13,000,000 people while LV has a metro area of about 1,700,000 people. Most of the land between the two is desert while most of the land between DC and NYC is populated making a right of way much more difficult to obtain there. The way the summary states that it connects to Disneyland, while possibly true, is really designed to be deceptive. It would have been much more honest if it said connects to LA and LV. There exists a huge amount of both car and air traffic between the two cities. Even with the high price of gas and a recent expansion of the highway between the two cities the roads are still clogged. While I don't know if maglev is the right technology a solid case for high speed rail between LA and NV can certainly be made.

Cheers,
Greg

An anonymous reader writes "The bill to ban genetic discrimination in employment or insurance coverage is moving forward. Is this the death knell of private insurance? I think private health insurance is pretty much incompatible with genetic testing (GT) for disease predisposition, if said testing turns out to be of any use whatsoever. The great strength of GT is that it will (as technology improves) take a lot of the uncertainty out of disease prediction. But that uncertainty is what insurance is based on. If discrimination is allowed, the person with the bad genes is out of luck because no one would insure them. However, if that isn't allowed, the companies are in trouble. If I know I'm likely to get a certain condition, I'll stock up on 'insurance' for it. The only solution I can see is single-payer universal coverage along the lines of the Canadian model, where everyone pays, and no one (insurer or patient) can game the system based on advance knowledge of the outcomes. Any other ideas? This bill has been in the works for a while."

Roland Piquepaille notes the hype surrounding what the University of Texas at Austin is calling the world's most powerful laser. During a tenth of a femtosecond this laser is 2,000 times more powerful than all the power plants in the US, and is brighter than sunlight on the surface of the Sun. On his own blog Roland points out that UT's is not the first petawatt laser; that distinction belongs to a system installed at Lawrence Livermore National Laboratory in 1996.

HighWizard notes the upcoming release, on Thursday, of a report by the US Geological Survey on the Bakken Formation. This is an oil field covering 200,000 square miles and underlying parts of North and South Dakota, Montana, and Saskatchewan. A geologist who began surveying the field, before dying in 2000, believed it may hold as much as 1 billion barrels of recoverable oil. Later estimates have ranged to the hundreds of billions of barrels. Such a reserve would go a long way toward securing US energy independence.

An anonymous reader writes "Two months ago I donated my old PC to my little sister, who is 7 — I had promised she would get her own computer as soon as she can read and write properly. I then proceeded to answer her questions about how it works, as far as she inquired, and tried to let her make some choices when installing Debian (she can already use GNOME). As I explained password protection and encryption to her, I was pleasantly surprised when she insisted on protection measures being as strong as possible, so that no one else can screw with her computer. She knows that my younger brother has to endure strict parental control software that was installed on his machine without his consent. The significant problem is that she cannot permanently memorize abstract passwords, even if they are her own creation. I talked with a teacher who assured me that this is common at her age. My parents would probably be able to guess non-abstract passwords. What mechanism of identifying herself does the Slashdot crowd suggest?"
