Help me to understand what entanglement really means. As it's explained above, I don't see how it's different than this scenario:
Take two playing cards, the king of hearts and the king of spades, and place them face down on a table. Mix them up until you don't know which is which. Have a friend pick one card without looking at it and drive away with it in his car. When he's gone 100 miles have him call you up. Tell him you will now perform magic and tell him what card he has. Look at the card that's remained with you. If it's the king of hearts, tell him he has the king of spades. If it's the king of spades, tell him he has the king of hearts.
I'm sure I'm missing something about what entanglement actually is but I don't know where I've gone wrong.
Here's my method: I put the ultravnc executable and an ini file with my encrypted password into a self-expanding zip file. The zip file also contains a batch file that expands the vnc executable on the remote machine, starts vnc, and makes a reverse connection to my machine. I used the Winzip Self Extractor to which allows a specified program, in this case the batch file that starts vnc and makes a connection to me, to run after extraction. I'm not sure but maybe that's also possible with 7-zip. Then I uploaded the self-expanding zip fle to a website. When a user needs to connect to me, I just tell them to go to the website/self-expanding zip file name.exe. The user gets a prompt asking them if they want to run or save the file. I tell them to click run. Then he gets another prompt telling him that the author of the program is unknown. I tell them to click run again. So the only thing a remote user has to do is go to a website address and click run twice and we're connected.
"With the new surface, you need a stationary table. Based on the images I've seen, I don't think it will work on an airplane tray or patch of grass, and definitely not in your lap."
Picture a very thin stiff hinged tray that folds out to an L-like shape. Put the tablet and keyboard on the tray, hold it on your lap, and type away.
There could be some kind of latches or velcro holders on the tray to keep the tablet and keyboard from moving around. The tray could be thin plastic or aluminum and stored flat against the back of the tablet or keyboard when not in use. A large part of the center area of the two tray surfaces could be cut out to prevent heat build up.
If I had more faith in the FDA I might side with them on this. But it seems that the FDA is now so heavily influenced by the pharmaceutical industry that I have my doubts. I think an important function of a regulating body like the FDA is to not only investigate the safety of a drug but also its efficacy. In my opinion, the FDA is very weak in that area. New drugs that are no better than old ones and possibly more dangerous since there is no long term experience with them are approved all too often in the name of profits. It seems that new drugs with very small statistical benefits over existing drugs get patented and approved. I'm not saying that all new drugs fall into that category but some do.
I taught myself VB6 (fool for a teacher?) about ten years ago mainly so I could write small apps and utilites for myself. Combined with Win32 api calls, it's been powerful enough for almost everything I've needed to do. True, my code isn't elegant but it gets the job done.
For a more modern object oriented language I think Lazarus (an open source Delphi clone) is in the same category as VB6. I found it easy to move from VB6 to Lazarus since the IDEs are similar. Lazarus is based on Pascal so some might consider it inelegant but it too gets the job done and the cost sure is right.
Couldn't you just power up the tracker once every 15 minutes or so for as long as it takes to report its position (maybe 30 seconds)? A CMOS 555 timer connected to a power transistor switch would draw only a few milliwatts when inactive.
Yes, I've had a similar thought about how economic predictions are different than physical predictions. If you make a prediction of a physical event like, say, the period of a pendulum based on its length, the period doesn't change just because the prediction was made. But if you predict an economic event, the fact that you did so can cause people to act based on the prediction and change the event. Maybe this is obvious and/or unimportant.
I assume, then, that you never shut your computer down for the night. Or for the weekend.
It's been my experience that most IT people rarely do this. I don't. Most of the people who do this are non-IT people who fear that if they don't watch their PC every second it's in use, terrible, dire things will happen. I've yet to have anyone in this category provide some sort of sensible explanation for doing it.
You're sleeping soundly in bed. Your computer power supply fails and catches fire. You'll never have to worry about turning off your computer again.
It's not in earth orbit. It's roughtly a million miles from the earth, so space junk isn't really a factor.
Thanks. Interesting. L2 being a popular place, I suppose there will be an L2 junk problem at some point. Also, I think I get your point about a shield not doing much good. I guess any defects caused by meteors too small to destroy the mirror will only reduce its light gathering power slightly if there's even enough debris to make a collision likely.
I'm wondering how the Webb scope mirrors are protected from micrometeorites and space junk. They seem so exposed in the pictures. The Hubble mirror, in contrast, is burried deep inside a tube with a hinged cover. I'm sure the question has been considered and solved for the Webb telescope. Does anyone know what protects the mirrors?
Speaking of the z axis, I just noticed that adjusting it slightly on my desktop keyboard made typing a lot more comfortable. I was already using the pull-out feet that give a slight angle to the keyboard but increasing the angle by adding a spacer of about 1/4 inch under each foot at the back of the keyboard made a noticible improvement. Maybe that's because I don't have my keyboard on a tray at an optimum height above my legs. Rather, I have it higher than that sitting directly on a table top. Anyway, the angle adjustment works for me and I suggest giving it a try.
Rather than a narrow air gap which might be delicate, I wonder if filling the space between the stationary and rotating parts of the heat sink with oil or even water would be better. Air has a thermal conductivity of.024. Oil and water have thermal conductivities roughly an order of magnitude greater. An objection to this idea would be the need for a low friction seal around the circumference of the unit but perhaps such low friction seals exist.
Good post. But, to play devil's advocate, the first homo sapiens 200,000 years ago had practically the same genes as anybody today. What they lacked was a culture that understood today's technology and could pass it on to offspring. 200,000 years of biological evolution produces little change. 200,000 years of cultural evolution produces revolutionary advancement. People from different countries differ little biologically but can differ greatly culturally. It seems to me that a culture that emphasizes education will grow fastest.
Of course, the hamsters must be fed and so the cost is not zero. But I have an idea that may be cost free or even negative in cost. Imagine a short ramp placed on the downhill side of a downgrade in a highway. The ramp is spring loaded to return to an up position when there is no weight on it. Cars and trucks passing over the ramp push it up and down. Linkage from the ramp turns a generator producing energy. You might argue that the system is stealing a bit of gas from each vehicle to generate the energy. That would be true if the ramp was on level ground but, since the ramp is on a hill and the driver would normally use his breaks to slow down, gas is not being wasted. In fact, the system is doing the driver a favor - extending the life of his break pads by reducing the amount of work they must do to slow down the vehicle.
When I was about 5 or 6 years old, I just assumed people on TV could see me like I saw them and I was careful to be well-behaved. I think it's natural for most kids to have the same experience since it mirrors what happens in real life. As I got older and learned how TVs work, I discovered that I was wrong and felt a great sense of relief and freedom. Now maybe I'll have to re-evaluate my position.
I was trying out iMule and saw that it uses a network layer called i2p that supports any application that can run using a proxy. You might want to give it a try. i2p is available at http://www.i2p2.de/ Here's a description of i2p from the introduction: ----- "I2P is a scalable, self organizing, resilient packet switched anonymous network layer, upon which any number of different anonymity or security conscious applications can operate. Each of these applications may make their own anonymity, latency, and throughput tradeoffs without worrying about the proper implementation of a free route mixnet, allowing them to blend their activity with the larger anonymity set of users already running on top of I2P.
Applications available already provide the full range of typical Internet activities - anonymous web browsing, web hosting, chat, file sharing, e-mail, blogging and content syndication, newsgroups, as well as several other applications under development.
Web browsing: using any existing browser that supports using a proxy. Chat: IRC, Jabber, I2P-Messenger. File sharing: I2PSnark, Robert, I2Phex, PyBit, I2P-bt and others. E-mail: susimail and I2P-Bote. Newsgroups: using any newsgroup reader that supports using a proxy."
Micro-editing at a word level is too crude. Try it at the letter level. You'll need to add a lot more drop-down boxes, but I find that the boxes add flair to the dull sequences of words in an article. Grammar Nazis will love it. Why stop at letters? Give us the ability to change fonts and colors too!
Analog tilt sensors and a few op amps might do the job better than silicon retinas and computers. But I take it the idea wasn't to get the job done but rather to explore the technology since there isn't that much of a real world demand for pencil balancers.
Math and Physics are beautiful in their generality. It's difficult to fully appreciate the generality, however, without having seen a lot of specific examples. That's why it's important to complete so many problem solving exercises. Math and Physics are taught that way but you really have to do the homework to grasp the subjects. It hurts the brain sometimes but it's worth it. Dr. Lewis attributes misunderstanding of math to poor teaching practices but I attribute it more to human laziness.
Yes, I've had the same experience with other types of products. I have a feeling that a product's perceived quality is often a function of advertising.

Yes, much better like _/__.
There's another advantage to a tablet tray vs a laptop, at least for guys. With the heat generating part vertical, you won't be toasting the marbles.

The idea only works until one of the cores starts sending spam. Hey core, want Vi@gra?

For less than 12 bucks you can get an excellent desoldering tool (Catalog #: 64-2060) from Radio Shack. Best thing I ever bought there.
