The actual article (not the headline) said sometime within the last 100,000 years, not 70,000 years. The 70,000 year figure was given for the theorized split between hunters and gatherers.
Also I see people quoting as fact that animals do not have a similar genetic bottleneck. Where are you getting this information? When this story was posted on Slashdot sometime last year, I looked for similar research on animals and could not find any.
The story I read last year was much more detailed in the methodology used to determine the existence of a bottleneck. They were not comparing genetic diversity with chimps, they were analyzing patterns of genetic diversity within the human race itself correlated with human reproductive patterns. Humans and chimps do not have identical reproductive behavior, and perhaps chimps (taking into account their own reproductive patterns) should have even MORE genetic diversity than current levels.
And I'd still like to see the evidence that "animals" do not show any signs of a recent bottleneck, since everyone seems to be generalizing "animals" from the briefly mentioned (and not explicitly studied) chimps.
Ok, so, ever run a air die grinder? Can get pretty hot, purely from the power of the air.
The point is that a vortex chiller tube (which actually are available for commercial use) uses energy to do thermal work. Maxwell's Demon was supposed to do thermal work with no energy input. I don't care if the vortex tube doesn't require a couple of fat D-cells or a gasoline engine, it's using air power to do thermal work.
I'd much rather deal with private companies than the government. Sure, they may be expensive, but look to the government for the ultimate in waste and overhead.
I don't have a land line, I use Roadrunner (which is $40 per month, and consistently above 2Mbps) and a cell phone. Unfortunately the tax is on cell phones now, and I'm not quite sure I understand why the Feds need to take about 36 bucks from every cell phone customer every year. Most likely to fund the extra work it takes to monitor cell conversations and pipe them back to the Big Ear.
I was actually taking opposition to the part where you said it sorts high and low energy particles without any extra energy. More specifically, the "without any extra energy" part. "Extra energy" is the inefficiency I mentioned.
Actually those tubes are HIGHLY inefficient. We use them to chill hot paper running at 600+ FPM in presses.
The efficiency (in terms of thermal energy per power expended) is somewhere near eight percent. A standard refrigeration cycle is far more efficient, because it is transferring just the energy, instead of the particle.
Maxwell's Demon depends on the natural motion of the molecule. Vortex tubes throw a lot of kinetic energy into the mix and use expansion characteristics to do the magic.
If you stood next to one of these tubes, you would know where all the extra energy goes. They are loud! And anyone with experience in compressed air know that it is very expensive.
JPG is great as long as it's a visibly separate page element, and you don't use them for anything requiring color matching. A lossless format is absolutely required when you need the image to blend with text or page backgrounds. JPEG compression usually skews the color one way or another, and not all rendering engines do it the same way.
That said, it's much easier to use contrasting colors for page elements and backgrounds. PNG transparency would be great for blending in as long as you don't need a razor sharp edge. Lossy images are great for reducing load times. JPEG with transparency would eliminate the need for lossless images in many cases....
I'm not a web developer, so don't stone me if I said something wrong.
How difficult would it be to do it with the golden popcorn, I mean, this is Weta we're talking about here. It's not like a cup of golden popcorn is that difficult to duplicate, I'm sure MTV would have provided enough information to make a 3D model or even sent an actual trophy. They could have made all of the nominees create an acceptance clip, possibly paying them for it. It would be obvious anyone that an acceptance clip would have to be prerecorded, so I'm sure that all the nominees would have one.
However, it's almost likely that Weta was notified long ago. The actual decision is not something they pull off at the last moment, it's not random. But the existence of popcorn has nothing to do with it.
License the channels for a yearly fee? Oh ho ho, then you'd really have something to complain about.
So a company could hop frequencies every year. Guess who has to buy new hardware when your old frequency suddenly doesn't work anymore?
It's best to slow down this process as much as possible. That way there's a semi-standard that ensures get use out of their hardware before it becomes obsolete.
I would like to add "clueless" and "gullible" to my list above.
Though I have spoken to quite a few Australians recently, and for the most part they seem to think Americans are OK. So maybe my list applies to "people who are intellectually handicapped and believe whatever mainstream tripe is thrown at them under the guise of being jaded and exposing the mainstream tripe."
I see the blue-in-grey problem with our Canon 1000's at work. Yes, we have several $80K color copier/printers, and the quality elicits tears of joy. They're so fast, they could print the counterfeit money to pay for themselves in ten minutes. However, the blue-in-grey problem would again surface....
That would highly depend on what major you would be in. A massive knowledge of poor spelling, vitriol, immaturity, and pompous blathering is not going to be useful in any degree, except maybe Philosophy.
As an engineer, I can say I've learned almost nothing from the Internet. There's a lot of what-if scenarios and photoshopped pictures, but little hard fact. It is of course invaluable if you are looking for a specific datasheet, and the company has made that available. But you don't magically absorb intelligence by slogging through the Internet.
It's like hunting for nutrition in a sewer, maybe someone flushed an intact bag of cookies down there. Randomly grabbing stuff won't help you though.
I made tables for both desks; they were the same width and height as the desk and nearly doubled the depth. We faced our desks to each other, with the tables in between, at the end of the room. We each had a loft on the side of the room, so we would sit under our lofts. The effect was a single large table with a desk on either end, monitors sat nicely on top and the computers sat underneath. An added bonus was that the tables formed a wind tunnel with the air conditioner, keeping the computers cold.
I went to an engineering college where laptops were mandatory. They've done it for ages...I think the original laptops were 486/33's.
I used my laptop every day, 16 or even 24 hours per day, for 4 years. The vast majority of classrooms had network ports and power outlets at every seat. Many professors required in-class laptop use.
I didn't find it useful for taking notes. If tablet PC's were around at the time, it would have been great: I can type as fast as the professor can talk, but I can't draw a picture or complex formula as fast. There was one kid who did everything in Maple, and would jump into Paintbrush, draw a diagram, and insert it into the document in realtime...but he was insane like that. But a tablet PC...if you can switch instantly from typing to drawing...would be excellent. One approach I found useful was to type notes on the computer, and use a notebook to draw formulas and diagrams. Then you can use the day's date and a reference number to link your text to your drawings easily.
Get a laptop. And...do NOT cheap out on this...the best four-year warranty you can buy. My laptop (an Acer Extensa 710T) used up a hard drive, a motherboard, a screen, a power supply, a power regulator, and multiple plastic parts including the entire top of the case and LCD bezels. Strangely, the battery did not die, and I can still get about 1.5 hours out of it. That's because I didn't succumb to the stupid "memory effect" myth that doesn't apply to Li-ion batteries. I simply read the user's manual where it said the battery was good for a couple hundred full-discharge cycles, and about a thousand partial-discharge cycles. So I only used the battery when no power was present.
People will say that a laptop can get stolen from you very easily. Never happened to me. Unlike a desktop, you can take a laptop with you! So the desktop is far more likely to be left unattended than the laptop...and yes, people do break into quiet dorms or apartments and steal computers. A cable lock is a good investment, if you want to leave the laptop in your room with the door open while you chat down the hall. I've known people to lose their computers that way. First few weeks every year are the most dangerous, because no one knows who everyone is on their floor.
I did have a desktop during the last year of school. The laptop was showing its years and was beginning to drag in the areas of MATLAB simulations and code compiling. So I used a mixture of VNC (laptop:Linux, server:windows), X (laptop and server Linux), and Remote Desktop (laptop:Win98, server:WinXP) to use my laptop as a terminal to my main computer depending on what OS was running.
You could get a better laptop, but figuring in resale value after two years, you'd spend another thousand+ to get a laptop that will still be two years old when you get out of school. Better to spend $500 for a new desktop, and have two computers to use.
PDA's are not useful until you get a job, where you have rapidly changing schedules and meetings to attend.
It would not be a bad thing if Microsoft grew to have an appreciation and respect for open-source software.
It would mean that open-source won, and proved its point. When the world of computing finally turns from infighting to cooperation, there is nothing that cannot be accomplished.
People don't think about what they're writing anymore. It's like they thought "Oooh, microscopic has a micro in it, which means a millionth. So if I say nanoscopic, that means even smaller!"
When in reality micro- in this context just means small, and -scopic refers to seeing. A much better choice of words would have been nanoscale. A buzzword in itself, but a bit more accurate.
Not so sure that's a good indication of smartness. As you said, Ximian is Gnome, and the programs were already in the menu. Hey, Redhat has always been smart enough to keep your menu settings, when upgrading from distribution to distribution. Even Windows does this.
Personally, I got the idea this Barr character does not have a clue. He oohs and aahs about programs like File Roller, which is included with Redhat 9 anyway. And...uh...spends a lot of time talking about how he changed his theme to Grand Canyon, which comes with Gnome also.... It was basically a review of Gnome 2 and Redhat 9.
Yes folks, the time has finally arrived. You know those annoying people who use Windows, and think they are Leet because they put the Taskbar up on the side of the screen? Now we got 'em in Linux. The geeks will have to find something more forbidding and difficult to move to, in order to maintain the technology separation from Joe Six-pack.

It's about connecting your wallet with the FCC.

I will agree they are cool, however. And hot!
Has to see and remember? Can't it just identify a particle as being high energy, for example by its size and speed?

I was merely making a joke, meant nothing by it. But now I believe all Australians are touchy, arrogant, xenophobic, and humorless.
This is interesting. All I need to do is figure out how to work for free, and still make money.
I think the only way to do it is owning a business, and selling stuff. Fruit stand!

In POV-Ray you can create any polynomial surface, not just cylinders and spheres.
Even if you were limited to a sphere, you could just subtract it from a box.
