This article focuses on the the basics of RAID...
The the the the editors must be be be be blind. How long ago did you give up giving even the most cursory inspection to the summaries? I know you all think it's only the headlines that matter, but some of us (i.e., all of us) readers wish you would do a little more, you know, editing.
So... what you're saying is that you agree with all of the previous posts that this is an inappropriate use of PDFs by someone who should definately know better, and you have nothing else to add to this discussion? I can't understand why people waste their mod points on posts like this.
If you're absolutely certain that you have a bad case of hypochondria, but you go to a doctor and he says you're not showing any symptoms and you're fine, does that mean you really do have hypochondria? I call this the Hypochondria Paradox.
I didn't think the point of the article was that Win2k supported old hardware or old software (I wouldn't be surprised if WinXP could do the same). I thought the point was that it was useable on slower hardware with very little memory. The implication being that WinXP, and probably Longhorn too, is a slow resource hog that forces people to upgrade their hardware. I kind of thought that MS was dumping Win2k a little too soon.
"can i post up little odd-end hacks i've created?"
Yes, but you have to make it sound like a revolutionary new technology that's going the change the world overnight. Don't worry, the editors won't check it out first. It's all about the headlines.
Actually he was right, H2O+EtOH boils below pure ethanol. There are both low-boiling and high-boiling azeotropes, and this one is of the former variety.
It's only non-volatile impurities that tend to extend the liquid range.
I was thinking Fahrenheit, and I didn't bother to check the exact number before posting. Yes, I know all about azeotropes. You can get pure ethanol from distillation if you add benzene at some point, but that wouldn't make sense here. And I've actually operated a 3 story continuous distillation column in the lab, so I know how complicated the process is.
...just for picking such a stupid name. I'm going to start a fast-food chain, but I can't decide whether to call it Flurger Fling, McZozzalds, or Glarglee's.
What I find even worse is when somebody writes "past time". That is, unless they're saying something like, "the Middle Ages are my favorite past time.";)
What are you talking about? You missed my point entirely. How do you turn wind or water power into energy? By generating electricity, of course. While this electricity can be used to generate heat to power a distillation process, it's better used as is. Heat is a lower quality form of energy, and only a fraction of that heat will be stored in the concentrated ethanol.
And, yes I know how distillation works; I have a degree in Chemical Engineering. You don't just heat the ethanol-water solution to 205 C and magically you get pure ethanol. A distillation column is much more complicated than that.
"Consider ethanol as a means to store energy from nuclear, solar, wind, tidal, hydro or other clean energy sources and transport it to your auto's engine."
OK, then how does one convert wind into ethanol? How about solar? These clean energy sources that you mention are used to produce electricity. But they can't even come close to meeting our electricity needs (with the exception of nuclear). So you're suggesting that we take this useful electricity, and use it in a very inefficient process to produce ethanol? If you need portable energy, just use H2. It's one step away from electricity, and it turns into water when it burns (with a small amount of NOx produced also).
So, first ethanol supporters say that it is a renewable energy source because it gets energy from the sun. Now that that has been thoroughly disproven--and this latest study is not the first to do so--they claim that it is merely an efficient energy storage medium. I wonder what the next argument will be when that has been disproven.
You don't seem to understand how ethanol is made. First, you plant some seeds. Then, you wait a while. Then you harvest the grain, add yeast, and wait a little while. Then you distill the ethanol from the resulting beer.
Now, what I fail to see is how hydro-electric or nuclear power is going to help in this process. Are you suggesting that farmers use nuclear combines or that distilleries use nuclear fission as a heat source. You're probably much better off converting these other energy sources into electricity, and using that directly to power a car, or using electrolysis to produce H2.
Wait, you actually expected Reuters (or any news organization) to get a tech-related article right?
The email date thing actually works sometimes. Once, my advisor had the date on his computer set to a month in the future, and his emails would sit at the very bottom of my inbox for month is I didn't delete them. Then I discovered how to sord messages based on the arrival time. Some email clients sort messages by and only display the sender date/time by default. Seems like that would be enough to fool the average PHB.
Sometimes that's not always possible. For example, if you set style.cursor to 'pointer', IE will generate a JS exception. You can catch this and then set style.cursor = 'hand', and the problem is solved. However, if you set style.position = 'fixed', the position will silently be set to 'static'. There's no way I can think of to detect this behavior. You just have to infer what the browser is some other way first, and set the position to 'absolute', which will work well enough in most situations. The point of these examples is that you can't simply check for the style.cursor or style.position attributes, because they exist on all modern browsers. I agree that checking the UA string is pretty pointless. It would be like checking a car's odometer if they could easily be reset by the owner. Hey, I managed to work in a car analogy!
Per CPU licensing was a simple metric that allowed software companies to scale their pricing so that it was fair to both the entry level and high end customers.
It may be good for business, but I wouldn't exactly say it's fair. If you came up to a lemonade stand that sold lemonade for $0.50 per glass with a friend and they charged you $1 for a glass because they assumed you were going to share, would you call that fair. I think if you get the same software, you should pay the same price.
Whenever I see Opera cheerleaders, I have to wonder if they've ever done any web development. Opera's ECMAScript is attrocious compared to Firefox's. If Opera would spend more time on following the standards and less time on stupid eyecandy like making buttons animate when you mouseover, it might actually deserve the l337 reputation it has.
Using the userAgent string is pretty much worthless these days. You can easily identify Opera by including some ECMAScript in your page--if it doesn't work, it's Opera.
...IE's share shrank to 86.56 percent from 87.23 percent.
I think that's supposed to be 86.563348237 percent from 87.23172395 percent. Also, someone should invent a symbol that stands for "percent" so we wouldn't have to spell it out every time.

Poor guy. That sounds painful.

4. They don't spend most of their time thinking of ways to explain why the Americans are more productive than them.
what r u talking bout ??? i would of modded you overratted if i had mod points !!! everyone nose slashdoters have excelent language skilz

IE is still way in the lead, but somehow I doubt that's who you were cheering for.
