Scheduler huh? Then it seems to me that this particular problem will go away when schedulers die.
In around 10 years we will have more processors than processes and threads, so each process will have its own private processor and no scheduling will be necessary (actually it will seldom be used, like HDD swap today with 4GB+ RAM). Think 100 to 1000 processors per machine.
Keep dreaming...
With all those processors, you'll want to be saving energy, so you'll be aiming to turn off individual processors until needed, and run the remaining processors at full load, so you'll still need a scheduler, locks, etc.
And yes, it's possible even today to use up more than 4 gig of ram and have to hit swap.
Slashdot's not supposed to be interesting to every reader all the time. If you want someone to cater to a least common denominator, you'd be better off somewhere else.
The simple fact is that, even on its' surface (pun intended), it's an obviously wrong comparison. The fact that an ice sheet that size would bend the earths' crust is, as I pointed out, irrelevent - the same mass only weights half as much on Mars. Even more irrelevant because the earths' crust is floating, so more weight would cause a plate to sink slightly, like getting into a rowboat - Mars has no plate tectonics.
On Earth, the weight of a similar stack of ice would cause the planet's surface to sag. The fact that the Martian surface is not bending means that its strong outer shell,
On Earth, a similar stack of ice also weighs twice as much... it's a questionable comparison from which to draw a conclusion without more information.

Zebra mussels continue to profoundly affect the Great Lakes ecosystem. This prolific mollusk filters microscopic algae from the water column, diverting nutrients from open water to lake bottom systems, thus favoring bottom-feeding fish (and their predators) over those such as alewife and smelt (and their predators) which feed in the open water. Aquatic rooted plants (macrophytes) and their communities (e.g. large mouth bass) thrive in water cleared by zebra mussel, while habitat is reduced for species adapted for turbid waters (e.g. walleye).
In other words, some fish benefited, others didn't.
In general, community abundances tended to increase at zebra mussel sites, but the diversity within those communities decreased.
In other words, more zebra mussels == more fish. The lessened diversity could easily be explained by the fact that it takes time for these things to shake themselves out.
Studies on the population dynamics of burrowing mayflies conducted by the Pennsylvania Department of Environmental Protection (PADEP), the Biological Resources Division of the USGS, Heidelberg College, the Ohio State University, and Penn State University have indicated that the mayfly populations in western Lake Erie and the Presque Isle Bay AoC are presently experiencing exponential growth. Based on population models, the mayfly population is predicted to attain full recovery by the year 2002. Mayflies were virtually eliminated from the western basin of Lake Erie by 1960, but recolonization began during the 1990s and spread throughout most of the lake by 1996. The recovery of the mayfly augers well for the yellow perch population which is expected to grow as the density of mayfly nymphs continues to rise in western Lake Erie. The re-emergence of the mayfly is seen as a prime indicator of improved water and sediment quality in Lake Erie.
Maybe those nasty zebra mussels can be given some credit for making the water clean... it's not like people were going to pay to set up a massive filtering system...
If they're full of toxins, then they're removing them from the water. That's a good thing, since otherwise the toxins end up elsewhere in the food chain. So the choice is now either toxin-laden fish (and the amphibians, birds, and people that feed on them), or toxin-laden mussels.
Some of those toxins are probably heavy metals. It might be interesting to do a bit of gene tweaking (maybe something simple as selective breeding will do it, since they breed fast enough) to get mussels that preferentially accumulate heavy metals. Then they could be "mined". Some things are only toxins because they're in the wrong place - the food supply.
Maybe the shells can be used as filler in concrete... they're already being used for no-growth boat bottom paint.
Maybe we should be putting mussels into the holding pens at sewage treatment plants.
Talk to anyone who does wreck diving in the Great Lakes. The water used to be really crappy - in fact, in areas it was about as opaque as a glass of lemonade. Or mud. Now it's a LOT clearer.
What we SHOULD be doing is laying removable mesh "beds" for zebra mussels to breed on outside every sewer discharge. Once a good colony is going, remove a portion of the bed each week and grind the mussels up for fertilizer or glue or fish food or whatever.
Henry Ford had the right idea - let people dump anything they want in the river, provided their water intake is downstream of it. After all, if you expect people downstream from you to drink it, you should be prepared to as well... the zebra mussels are doing a lot of the work that we should be doing, but aren't.
Look at the people pushing it. Warren Kinsella has a history of being a Liberal party hack. He had his 15 minutes of semi-fame long ago, and will do anything to try to get back into some sort of "spokesperson" role.
The law was well-intentioned. It was to provide protection to groups of people akin to the prohibition against "shouting fire in a theatre". Unfortunately, it doesn't work when people subvert it with their own agendas. As a practical matter, it may not be possible for it to work, period, and if that's the case, it should be scrapped.
Run by reasonable people, it could work. Problem is, everyone thinks they're "reasonable", and almost nobody else is as "reasonable" as them...
If soneone's an asshole, I should be able to say so without fearing being hauled before a tribunal under the pretext of a "hate crime." Reasonable people will be able to figure out who's telling it like it is, and for the rest, why would I give a flying f*ck what they think?
By 2020 it won't matter. Everyone will have a wireless palmtop that connects to the local mesh|lillypad network for internet/phone/video calls/etc.
You can already do that with a lappy - it's just a question of shrinking it down more, and getting more people to "donate" their unused bandwidth to the mesh.
This is not completely accurate. I am in Canada and I had gotten a Grand Central number. Maybe it is for US and Canada only but, how hrd (sic) is it to use a proxy in the US to register (or ask a friend to do it) and use that phone number if you want!
You can't get an area code that's local to Canada. I looked it up. Kanuckistan isn't exactly 3rd world. Also, you're in violation of their TOS. Why not just grab a copy of iCall (to talk to phones) or Eyeball Chat?
Good luck getting acceptable wireless signal through concrete.
Try the newer wireless "n" - it works in stair wells, through walls, etc. much better.

I brought one to work Monday (I figured I'd give dlink a try - my other one is a linksys - and I'm pleasantly surprised at how good it is) and it works in stairwells, in the restaurant downstairs, etc. I'm surprised... but I'm not complaining.
The commander-in-chief has an arrest record, and so does the veep. Not only arrest records, but convictions.
Over here, to get employed, you're normally required to sign a release form that gives the hiring company the right to do a background check on you. They can then get arrest records and credit records for the last 7 years
So don't sign the form, and say you have religious reasons for not signing it - you belong to the church of the privacy-hugging atheists...
Seriously, if everyone refused to sign such stupid forms, they'd force companies to hire on *merit*. Arrest records mean nothing - convictions are what counts. Ask anyone who has a crazy ex, or who's faced retaliation for reporting child abuse, or picketed to protest in support of a cause.
It would also depend on the infraction they're planning to check out. Get fresh and your minor traffic violation may also include -*SMASH*- driving with a busted tail-light. Oooh, and I think I saw you move through a stop sign too. And whatever else he decides he saw.
Even if you go to court and argue these things (a cop's word against yours), you're still out time and money.
They really can't do that too much any more, not with surveillance cameras in their cruiser recording stops, and with the preponderance of people walking around with cell phones that can take movies. Ditto lap-tops with web cams.
When you're pulled over, just hit "record", either on your cell or your laptop.
The linked entry is for the 3rd murder trial I've been involved with
Sounds like trouble follows you around.
Tell me about it... I have a theory that, if you take a million people, and the odds of something REALLY weird happening is 1 in 10, then you've got 100,000 people who are affected. Now, repeat, 1 in 10 of those, or 10,000, will have two really weird experiences. One in 10 of those, or 1,000, will have 3, and 1 in 10 of those (100) will have 4. 10 will have 5, and 1 (that must be me) will have 6 or more.
It's just the odds - it had to happen to *somebody*...
That's funny, because Canada Customs asks if you've ever been convicted, or if there are any charges currently pending. Your family member must have tried to cross when the charges were still in the "pending" stage.
Either that, or there was something else that made them not pass the "smell test" - customs agents on both sides of the border can make arbitrary decisions based on instinct and training.
You don't get a criminal record just for being arrested - at least not under those places where it's "innocent until proven guilty." Heck, even those places where it's "guilty unless you prove yourself innocent" you don't get a criminal record until you're actually *convicted* of a crime, not just charged.
If you're innocent, you have NO reason to talk to the cops - they're not the judge and/or jury, and anything you say can and will be used against you.
If you're guilty, , you have NO reason to talk to the cops - again, anything you say can and will be used against you.
Either way, STFU, because "anything you say can and will be used against you!
Agreed. What's the worst that will happen if you refuse to "cooperate"? They charge you, you get released unless they have really good evidence, and when push comes to shove, you get to tell it to a judge, which, if you're innocent, is what you want to do.
Think of the police as civil servants... do you REALLY expect that telling them anything is going to help you if they wrongfully believe you're guilty of something?
And no, the judge isn't going to hear the prosecutor say "the defendant didn't cooperate with the police by answering all the questions they asked..." unless said prosecutor is feeling constipated and wants their ass reamed out.
The judge knows better. If arrested, no judge is going to say anything beyond "Talk to my lawyer."

The great lakes were dying from pollution before the zebra mussels.
At least the water that goes downstream is cleaner than it would be otherwise.
