No. Clusters are only good for doing tasks that "parallelize". Compiling is too linear.
Compiling parallelizes quite well. See distcc and XCode/Rendezvous.
I stand corrected. I was thinking along the lines of parallelizing the compilation of a single module. I hadn't really considered compiling multiple parts being compiled and then linked-- duh. Still, he'd probably be better off compiling on a single 500mhz machine than splitting it up across several old 133 or 166mhz boxes, considering the likely difference in memory.
Libertarians actually hold very right-wing/conservative views;
Actually, I'd say Libertarians hold views on certain high-profile topics that are most commonly associated with right-wing conservatives (e.g. right to bear arms, the free market, and small government). The fact that right-wing conservatives don't actually stand for those things so much anymore and really just pay them lip-service occasinally is usually overlooked.
the only way they get called liberals is because they don't think the government should get in the way of much of anything.
Exactly. Opposing things like military intervention in foreign countries, having a standing army in the first place, and limiting immigration could all be considered "liberal". But most lefty-liberal types don't even oppose those things anymore, so those beliefs just get one labelled a "kook".
Because in a civilized society, the population grants the government a monopoly on the use of force. Extended to the planet, America seems the natural choice. Extending a governmental system with a judiciary, an executive and a legistlative branch to the planet, you end up with the World Court, the United States, and the UN.
The US is the world's police force, the US has most of the guns. From a practical standpoint, why NOT grant them the monopoly on force, since they've (typically) shown respect for liberty in the past. Name a country who has shown MORE respect for liberty, not in the "you should be free from being poor" sense, but in the true "you are free to do as you like, but eat what you kill" sense. It reminds me of that scene from the Life of Brian:
REG: All right, but apart from the sanitation, the medicine, education, wine, public order, irrigation, roads, a fresh water system, and public health, what have the Romans ever done for us?
XERXES: Brought peace.
Stupid mods. Just because you disagree with the above quoted parent post doesn't mean you should mod it "troll".
Also, a side note. How much extra computing "power" is gained by adding an extra machine to a cluster?
Depends on how big the cluster already is. Are you adding one machine to a cluster of 6, or a cluster of 600?
For example, I have about 7 or 8 pentiums (most are 166's, there is a 133 and a 200) sitting on the floor collecting dust. If I hooked them all up together, what would the usefulness be?
Practically none. Buy a single 2.4GHZ Celeron box off eBay for $200 and you'll get nore out of it.
Could I compile programs quicker?
No. Clusters are only good for doing tasks that "parallelize". Compiling is too linear. Besides, it's not like you hook up 8 machines to a 10/100 switch, start up a few "cluster daemons", and end up with a single virtual machine. Clustering generally requires software customized for the specific class of task you wish to tackle.
Would a cluster make a good web server, jps server?
You can have multiple machines serving the same web content, but that's not really clustering, per se. That's just load balancing.
the damage done to USA's credibility will take 100's of years to repair
If only that were true. On the scale of bad things that people do to one another, the Abu Ghraib incidents are such small potatoes that, 10 years from now, you won't be able to find any significant number of people who'll cite the Abu Ghraib torture as even one of the top ten reasons they hate the US.
As for the UN, it's hard to take anything they say seriously when they selected Libya to chair the United Nations Commission on Human Rights...
. ..what happens when they do a source code audit after these are found and track down the programmers who put 'em in.
I believe that's "give them a bonus and a company car."
These back doors are not trojans installed by disgruntled employees, but there by company policy.
I'm always astounded when others are astounded by the existence of back doors in things. Pretty much anything that takes a password has a backdoor in it. Phone systems, voicemail systems, even those telephone entry systems on apartment buildings; all got back doors. Tech support is hard enough already without having to deal with unknown passwords. Some are better than others, though. Sentex telephone entry systems have back door passwords that are a hash of the unit's serial number, and only Sentex tech support has access to the program that generates them. Not that one usually needs the backdoor; most Sentex units I see still use the factory password "000000"...
Was the link you posted for "Fox News" and "Junk Science" or "Junk News" and "Fox Science"?
Haw haw, yes, funny. It's a Fox News story posted on JunkScience.com. If you find that particular messenger distasteful, you can read a dreary list of 100 counterpoints, complete with references to even duller source material, to the oft-repeated anti-DDT hysteria. Personally, I don't think the DDT ban made much difference one way or the other. I think it makes for a good cautionary tale, though, about taking something as truth just because a large group of people fervently believe it. This goes for anything, be it pesticides, armageddon predictions, or invasions of foreign countries.
People in California don't have basements, you insensitive clod;) Seriously though, we tend to build our houses on small stilts for some reason.
This is true, I know. I guess I was exaggerating to make a humorous point. I myself have lived in California for 30-odd years, and the closest I've come to having a basement is my current house, which has 24 inches of crawl space underneath.
Yes, but it's good to calculate your risks. Some things ARE more dangerous than others. I'm glad they "phased out" asbestos, for example. (In new construction at least)
Asbestos isn't nearly as dangerous as the hysteria about it would have us believe. It's really only a risk to those working with it in continuous, heavy concentration-- mining it, building with it, etc. Incidental exposure is nothing worth worrying about. Millions of acres of California are underlain with chrysotile asbetos bearing soil and rock-- most of San Francisco is built on it-- and people aren't dropping dead from mesothelioma every time they dig a new basement.
Yes, you get what you pay for, but when something like this happens it doesn't necessarily mean the individual is a moron, it means she can't afford anything else.
I agree with you completely, but I think we can pretty safely assume that Alexandria Felton, who lost "the itinerary for a recently purchased trip", probably can afford a computer and is likely just another fool who thought her data was safe with Microsoft.
How can you claim that you've created these fractals? Aren't they rooted in mathematics? Wouldn't that mean that you just ripped off your art from Math?
FWIW, he never actually claimed to have created any fractals. He just said that "a lot of work that went into each image". One could argue, I suppose, that fractals are only discovered, not created. But then again, a lot of creativity has to be applied in the presentation to turn them into something that could be considered "art-worthy". Mandelbrot's initial graphs of the Julia Set were crappy monochrome blobs done on a dot-matrix printer with a bad ink ribbon-- you'd be hard pressed to find anyone who'd call it art. The beautiful rainbow colored images you see are carefully composed and selected representations of fractals. The composition and selection could be considered artistic. I'd say it's no less an art form than photography. Photographers don't claim to have created the content in their photographers-- they just capture images of it.
Drop the price of a CD to $10 US or even close to $5 US.
It didn't work for DVDs. It certainly won't work for music.
It didn't work for DVDs? Sure worked on me. I've bought DOZENS of movies on DVD in the last couple years, mostly because they're so cheap. I haven't bought a music CD in two or three years, mostly because they cost too much for what you get. This is all mere anecdotal evidence, sure, but when I go to the supermarket I still see racks of older movies on DVD for as low as $4.99. If selling DVDs cheap isn't working, they've sure been letting it not work for a long time!
Processor IDs are hardcoded and unique. Thankfully, they can also be turned off.
Yeah, "thankfully" they can be turned off, in software. I have a CD with a program that can turn the ID on and off inside of Windows. It can be stealthily turned on and off at will.
This is probably just how DRMs going to be implemented too.
(shrug) They're not likely to institute DRM requiring a processor ID any time soon, as Intel is the only CPU mfr providing that "service". Good luck pulling a CPUID out of a Transmeta or AMD!
i think they should rename it 80+ tho, since everyone seems to drive that. well in centeral calif anyway.
If you're going to do that, though, they should also rename certain portions of it "dear god, what's that smell?" and "hoe much more california can there possibly be north of Sacramento?"
Hate to break it to you, but most of Elena's trip has now been definitively been proven to be a fake, specifically the part where she actually rides through Chernobyl on her bike. She (her husband? can't remember) also apparently re-arranged some kitsch to make a better shot.
The trip was NOT faked. The only misleading element was the intimation that she rode it alone.
I sell you a plow... you buy my plow. I rig the plow to not function from 5-9. You however, enjoy plowing in the moonlight and this is a problem to you.
I also sell the same identical plow, but without rigging it, for $500 more.
Perhaps it shouldn't be criminal, I was speaking on a relitively loose basis. It is however blatent price inflation and distasteful as hell... something consumers should be on the watch for.
So I don't necessarily disagree with you, but perhaps that analogy will provide someone with the reasons on why it is so very distasteful.
Distasteful, sure. But I won't buy a plow that locks up at night if I want to plow at night. Or maybe I will and I'll hack the clock on it. Nobody should be able to stop you from selling such a plow, and nobody should be able to stop me from doing whatever I please to the plow once it becomes my property. Seems simple to me. So long as you let buyers know the limitations of the plow, everything turns out fine.
Just to mention that the 10D does have different hardware, so this hack won't give all features,
notably the faster frames per second and frames that are buffered.
The EOS-300D will shoot 4 frames at 2.5 frames per second and the EOS-10D will shoot 9 frames at 3 frames per second.
Also, the EOS-300D has a cheap-feeling plastic body while the EOS-10D has a black magnesium body.
The 10D also has TWO control dials and uses a prism reflector rather than a mirror. I don't think Canon will care about those few willing to flash the firmware to enable a few extra features on their 300D and voiding their waranty...
I never had a problem with Intel's processor ID. Every networked computer already has a unique MAC address. What is the difference?
MAC addresses can be changed by swapping out a $15 part and in some cases can be changed in firmware, so they're not an effective tracking/identification tool. Processor IDs are hardcoded and unique. Thankfully, they can also be turned off.
The average computer user in 1970 could probably figure out how to turn on WEP, were he/she transported to the present day.
Back then, my father used to program computers. For AT&T. I had to teach him how to use a mouse. He knows he doesn't know how to use a computer beyond a few specific applications.
I thought of that after I posted. My father too used to do software work writing in assembly for radar systems built by Hughes Aircraft. He's been managing projects for the last 20 years, so his direct experience with computers of late is limited to Excel and Powerpoint. He's now one of the most dangerous people to put in front of a malfunctioning computer because, as a former software engineer, he thinks he should be able to figure out what's wrong. I suspect the "older folks" have succumbed to a certain mental "hardening" that makes it tough to keep track of all the newe stuff. I bet if you put them in front of a WAP config screen thirty years ago they'd have it figured out.
OTOH, I should also point out, that this type of copy is often made from the projection booth. Good luck scanning the audience for that piracy problem.
So those people that kept walking in front of the camera on the last CAM that i watched had to be, what? 30 feet tall?

Great geek; terrible driver: http://www.mit.edu/~jfc/right.html
Most of the drive being through california, he was only required to move to the right lane if someone driving faster came up behind him.
If you're going to do that, though, they should also rename certain portions of it "dear god, what's that smell?" and "hoe much more california can there possibly be north of Sacramento?"

By what rationale? Neither "crippling" by the manufacturer, nor "uncrippling" by the end user should be a crime. Making either illegal is sheer idocy.
