Er, the link I just posted is to a review by Wired Mag about a new 3-D printer that can print in color. It's supposed to be useful to printing out molecules, handhelds, etc.
I guess you can print out those action figures in color too! All you have to do is cough up about $60k dollars.
I've heard of 3-D printers like this one (that construct an object using cornstarch) for years but are there any others that have builtin lathes, molds, drills and such?
I used to entertain the thought of buying one of these just to be able to design some cool sculpture and print it out.
A good link is here, but I don't think that's what you are really thinking about. The Coriolis force relates more to moving objects (and their forces) on the surface of a rotating sphere IIRC.
which allows you to define a container "mydoc" that contains further more specific containers like "toc","instructions" and "index". The Eidola code looks like you can dynamically extend a variable to create an arbitrarily complex data structure. So like with XML, you can keep adding more specialized containers to the root.
It could be a cool concept, but the web site makes it extremely difficult to figure out what the subject matter is all about.
Some example, any example of some sort of code took forever to find. But here is something!
It seems to be an implementation of this Eidola language in Java and gives a very brief example of what appears to be Eidola programming or whatever passes for it.
Here is a snippet of the example from the page:
Here's a simple example to get you started:
new Class c
new Variable v
v setType c
v setSuperElement c
c addPublicMember c.v
It would seem we would have to relearn quarantine the hard way. We do it to pets, but not to people. Silly isn't it?
We still quarantine people. I remember watching a Nightline story where they talked about the problem with the spread of the anti-biotic resistant version of tuberculosis in New York a few years ago and they managed to contain it to a few people. Inorder to contain it, they had to quarantine those people. As I remember, some of the people had been under strict quarantine for months...possibly even beyond a year...whatever it took for them to get over the special version of tb or probably to die from it.
It is not acceptable to have djbdns working differently on different machines; any variation is a bug. If there's something about a system (compiler, libraries, kernel, hardware, whatever) that changes the behavior of djbdns, then that platform is not supported, and you are not permitted to distribute binaries for it.
I think that the reason he uses such draconian language is that he wants to ensure that any modifications by a programmer will not make djbdns less secure. I think it would be pretty easy for any new code to make his code less secure, if for instance, you were to add a system call using data from a remote machine.
Also if porting to a different machine there may be other architectural/security considerations to keep in mind and trying to force djb's code to fit into that computer architecture may break its security model. That's probably why the license is the way it is.
He does give you the option to send him a request for license specifics if perhaps you might want some leeway but that would be on a case-by-case basis.
I don't think we do know whether or not this affects matter. It might change the properties of matter that contains left-handed nuclei.
What if a left-handed version of H20 was created that acted like the ice-nine in Kurt Vonnegut's Cat's Cradle. Ice-nine in the novel was supposed to "freeze" regular water on contact regardless of the temperature.
You'd think that the oblong nucleus of left-handed nuclei would cause the orbits of any electrons to go out of kilter?
Actually, if you're in New York you probably don't have to worry about the Ebola when you should worry more about Tuberculosis (especially the antibiotic resistant one). I read in a book (can't remember the book maybe it was the hotzone?) that said that a survey of people admitted to one New York hospital revealed that 50% of people had tuberculosis.
This is scary but it turns out that one of the local neighborhoods has a particularly high concentration of tuberculosis bacteria in the air. I'm not sure if it's at dangerous levels but it's still scary.
"The operational details and future targets, in many cases, are hidden in plain view on the Internet. Only the members of the terrorist organizations, knowing the hidden signals, are able to extract the information."
If only the members of terrorist orgs know the signals then how do they know about it?
My guess is that they're tracking encrypted messages on the internet, telephone and wireless and then they probably try to figure out if the parties on either end are shifty characters via background checks or racial profiling. How else would they know this stuff?
Since most people probably don't use encrypted email or what not it would probably be a really useful technique for law enforcement agencies.
I'm not sure that it is called that. The pump I'm talking about that is the current rave is basically composed of a cylinder with a small screw-like turbine that pushes the blood past it. No balloon type device is involved that I can remember.
I think they've come up with a new technique to get around the blood clotting problem by smearing the interior of such devices with a sticky finely ground sand that they then expose to blood and allow it to clot. The clotted blood is now firmly glued to interior of the device and I think that is supposed to reduce further risk of clots in the device making their way to vulnerable areas.
Yeah the Jarvik was the first completely artificial heart to be used by a human, but unfortunately Barney Clark did not survive. I understand that they tried using the Jarvik 7 a few more times after that but the patients kept dying after a few months. They finally gave up on that design and resorted to a different concept, that of, making helper pumps. These are not replacements for the heart. They are implanted next to the heart and help the diseased heart to pump. Apparently, they can help the diseased heart to become more healthy by relieving the amount of work that has to be done. I think Dr. Jarvik is now working on these "helper pumps". It seemed that the completely artificial heart was technically infeasible at this time but who knows how successful this new artificial heart might be?
If designing by committee is so bad then how does Apache seem to function? I'm under the impression that it is composed of a "core" of developers that vote on whether to add a feature or whatever. It seems to be successful. Or does this type of development require different politics than OS development?
Your interpretation is disproven by the fact that Pons and Fleischman are still alive. If cold fusion had actually been happening at any time, they would be dead from the neutrons.
The problem with this statement is that you're claiming to have all-knowing knowledge of physics and chemistry which we don't. According to the "cold fusion" experiments, they amount of neutrons they detected was 10 times less than would be expected if nuclear fusion was occuring...so perhaps that is why they are still alive. If these effects are cold fusion then a theoretical explanation will have to be developed that explains it. Other weird effects such as the Mossbauer effect and high temperature superconductivity were also things which were not thought to be possible though they were more readily accepted. No doubt, the huge media blitz that surrounded the publicity on the initial cold fusion experiments killed any mainstream acceptance of this field.
Read this essay about cold fusion from a non-believer. He gives a very fair portrayal of cold fusion. It's pros and cons and does go on to say that he doesn't believe in it but he does believe that one of the people doing research in this field is doing ethical, careful research that seems to yield promising results. The author of this essay is a physicist and not an electrochemist.
Also in the essay the author notes that cold fusion researchers consistently get positive results when they dope the palladium rods with enough deuterium that the ratio of deuterium to palladium is above 0.85.
I am also not a believer in cold fusion. I don't know if it's for real or not but I prefer to keep an open mind especially if they are doing careful experiments and getting positive encouraging results. It is better for them to actually try and see what is there then to ignore it and hope it goes away.
Unfortunately, it seems like in the cold fusion debacle that the news of the possible discovery escaped before the scientists themselves were ready for it to happen. Also I think they were afraid that another researcher with whom they were in competition with was about to announce something. At any rate, one of the key problems with cold fusion research is that it seems to turn out that the process of cold fusion (if it even actually happens) only occurs if the palladium rod has a certain kind of composition. There were apparently experiments where they used certain palladium rods that was pretty uniform in their composition (composition possibly being atomic structure/impurities) and when used these specific rods produce the heat that was expected; however, other pieces of palladium that did not come from the same rod but from other rods that probably didn't have the right composition did not cause successful experiments. The problem of making a successful cold fusion experiment seems to be rooted in being able to successfully create palladium rods that have the right composition. This is a materials science problem, I guess.
So, it would appear that Pons and Fleischmann probably accidentally hit upon the right kind of Palladium rods and when others tried the experiment they simply didn't have the right materials.
Another case of the establishment trying to put it's collective head in the sand. See this other slashdot linked article. It's about the scientist who discovered a way to turn adult cells into stem cells.
This quote is very telling:
So unlikely does the claim seem to many biologists that she has found it impossible to have it published in leading journals. But now, she says, it has been replicated by one of the world's leading contract research companies, Covance, and a company has been set up to market the idea.
Yes that's right...the journals seem to not want to publish her possibly ground breaking results. If her work is for real, then this is sad. If not, then it's better we find out.
Also see this quote:
One leading scientist familiar with her work, Professor Adrian Newland of the Royal London Hospital Medical School, said that he had repeated her experiments with the same results.
"It's fascinating, but there could be other explanations for what is going on," he said. "My own work suggests that it isn't possible to reverse the process of differentiation, but I have repeated her work and got similar results. I think more research needs to be done to eliminate other possible explanations. As it stands, it could be amazing, or it could be inconsequential."
I find it remarkable that another scientist has reproduced her work and gotten similar results and yet he doesn't want to believe his eyes simply because it would invalidate his previous work!
"Dean's two-wheel balancing device is really cool," said Dr. Wise Young, director of the W. M. Keck Center for Collaborative Neuroscience at Rutgers University. "It zooms around like lightning just by standing on it and leaning forward or backwards. The battery is the platform. Using it is totally intuitive. It will require reorganization of sidewalks because there will be people zooming all over cities with it."
The site is called "Independence Technology" or could that be short for IT? Remember that Johnson and Johnson is going to be selling the iBot for DEKA.
IT is the PR (Personal Robot)...

What is 'IT'?

Think about it, it makes sense. When I thought about what was one of the most useful things that I've always wanted, that is, a personal assistant...it simply makes sense that a personal robot would be very useful. Plus it would be the logical extension of the PC.
Also since the invention was described as replacing something "dirty, expensive, sometimes dangerous and often frustrating" it mean that it would replace a human assistant.
Also this kind of thing wouldn't be that far out since Honda recently demo'd their walking robot and Kamen demo'd his iBot. Also text-to-speech (http://www.lucent.com/speech/) and speech-to-text (http://www.lhsl.com/) software already exists. The hard part would be gluing the stuff together so that the robot would be easy to use and useful.
It would be revolutionary, fun, possibly cause legal concerns (what?!? have robots walking around?) and cities might have to be designed around them to give them a separate lane to travel from point A to point B.
The invention has a fun element to it, because once a Ginger was turned on, Bezos started laughing his "loud, honking laugh".
Not sure how to read this. How could a scooter/car/whatever be fun? Perhaps the mention of a hover device awhile ago (they've been available for years) could look 'fun' when activated.
The invention could be fun if it suddenly stood up when turned on! Imagine that it is a one or two wheeled scooter that was laying down on the floor and when turned on the handlebars or whatever suddenly rised up as the wheels spinned to stabilize the darned thing!?!

Hmmm...I thought that the UNIX philosophy was "no news is good news"...meaning that in this case tar should only show something if an error occurred.

XML is like:

Pretty cool. Up until now I thought these were two totally separate fields. Looks like they are using MEMS technology to reach the nanoscale.
Looks like someone cracked.
