I think the reason for the "glowing butterfly" in the ad is that it is actually a Luna moth. I think they are playing on the luna - moon - night time connection with the name and the moth just happened to make a nice mascot.
If all of my atoms get replaced every few years, how come I have a tattoo that is over 15 years old and looks nearly identical to the day I got it? I don't think my body is replacing the ink. I realize the atoms in the ink were added to my body, but so were the ones in my bones and teeth. I also have scars and moles that have been the same for decades. I'm not saying that cells aren't constantly multiplying and dying, but I've always wondered if a lot of the atoms get recycled locally, and therefore some have been there for a long time.
I agree that it doesn't matter if my body changes overnight or my brain shuts down during surgery, I'm still me. A perfect copy of me wouldn't know it was a copy, and wouldn't care.
I'm just curious to know how often the body replaces atoms; especially metals and in places like tooth enamel, bones, nerves, etc.
Are you kidding? I recently bought a baseball for my nephew, and every single one of them in the sporting goods store was made in China. I do my best to avoid products from China, but when you can't even buy a baseball that's made here in the states I'd say the battle is already lost. Obviously I didn't NEED a baseball to survive, but if you refuse to buy anything from China you won't be doing much shopping this Christmas. Of course not buying crap you don't need is usually a good thing, but that's another subject.
The problem with using this for general aviation is that you have to carry water in addition to the fuel, which adds lots of weight. Most GA aircraft engines are air cooled for this very reason. It's definitely an interesting idea, but I think it will be much more useful for vehicles that don't have to overcome gravity. For the immediate future, I think diesel engines that can run on jet fuel, pump diesel, biodiesel, or possibly even vegetable oil are the best bet for small aircraft. The 100 low lead aviation fuel that most GA aircraft use is expensive and not very environmentally friendly, and because of that I think it has a limited life. You are correct that any change that happens will be painfully slow.
I'll second the vote for pure-ftpd. I can use virtual users for my friends who understand ftp, anonymous logins for relatives who only know how to use a browser, and an actual unix account for myself so I can access the majority of the file tree. Of course it doesn't offer encrypted logins that the original post was asking about, but it's great for a simple FTP server where you don't want to give out actual unix accounts. Initial setup is easy; you can use the included commands for adding virtual users, or you can edit the config files if you prefer.
I agree with your sentiment, but just to be anal; it's Old World, New World, and Third World. The US is part of the New World, and will be even after the dollar becomes useless and our GNP is less than that of Bangledesh.
Solid Works is fine for simple individual parts and small assemblies; but if you want to design a large assembly or complex molded part it still can't compete with Pro/Engineer. They have made a lot of progress in the past 10 years, and lots of people feel the way you do. However, if you are serious about design you should take the time to learn Pro/E. I've been a design engineer for over 10 years, and I can tell you there is no substitute. It's not that hard to learn considering the power of the software, and the price difference is minimal. The reason it seems more difficult is that it requires you to properly define the entire part. This is annoying to graphical/industrial designers, but it is vital for properly engineered parts and assemblies. The first time you design a complicated machine with hundreds or thousands of parts, and it fits together in the real world exactly like your Pro/E model, you'll never want to use anything else. I don't work for PTC, and at times they are quite annoying as a company; but they make the best 3-D modeling software at this time.
OK, you do indeed have a hot water heater. Most people do not however. I've seen those in commercial kitchens, but why would you need one in your house? 190 degrees seems like overkill for washing a few household dishes.
It is either a "water heater" or a "hot water tank", NOT a "hot water heater." If the water is already hot, you don't have to heat it. AAAAAAAAAGHHHHHHHH!!!!!!!! No offense to you, but that phrase just makes me go a little bonkers.
As an engineer, I just had to see if it really was that easy, so I ordered a set of "bump keys". So far I haven't been able to open my front door lock, an older door lock of the same brand, or the padlock for my bike. I haven't tried any others yet. Maybe I'm just a complete klutz, but I don't think it is near as easy as the media want you to believe; especially on older cheap locks that have a lot of wear. Based on the way it works, I'm guessing new locks manufactured to higer tolerances are probably the easiest to open. A lot of locks are difficult to open even with the proper key once they reach a certain age. It's far easier to break a window or find one that's open if someone decides they want to rob a house. If you are really that paranoid, get a big dog. Technology will probably never surpass man's best friend for security.
Weight. Recumbents have longer frames, and often a single tube has to bear all the loads. This makes them considerably heavier than an upright bike. That is the main reason they are slow going up hills. Personally, after owning a recumbent, I'd never want an upright bike for travel over smooth surfaces unless I had to climb mountains. I never had much luck generating more power in a climb than my body weight like the serious bikers can accomplish. The main disadvantages I've encountered with mine is that I can't see over my shoulder behind me as easily as with an upright (the rest of the view is a little better). I'm harder to see for all the people driving automobiles, and sometimes that is frightening. Finally, since you are sitting down you can't use your body weight to "throw" the bike around like you need to for off road riding, jumping over curbs, or avoiding sudden obstacles. I've seen people pop up the front wheel of a recumbent to go over a curb, but it takes far more strength and coordination than most people have. For distance riding they are so much better than an upright, but a mountain bike with front suspension is a much better off road or urban assault vehicle.
Exactly. You can still skip the "naughty" bits, or cover your eyes, or anything else you want to do with "your" copy. What you can't do is modify something that you don't hold the copyright to, and then re-sell it. If you are against copyrights, that is one thing; but the way the law currently reads, this is the right decision. Imagine if some company was taking movies and making them "racially & ethnically pure" or some such nonesense. Every minority character would either have their skin tone changed, be removed, or have their name prepended by a racial slur; just like "nigger Jim" in Huck Finn. Do you think we would be having the same argument? How many of you think that should be legal? As disgusting as it is, I'm sure there would be a market for it; just like there is a market for "sanatized" films. Can you imagine what the KKK would do with films like "Roots", "Crash", or "Amistad?" The right to control derivitave works is actually one of the parts of copyright laws that is relatively sane.
That's not what I was concerned about. If you only have a certain amount of water to begin with, and in order to drink it you have to purify it with RO, then the amount of water you waste is VERY important. If this is being used for desalinization next to the ocean, then you are correct; it doesn't matter. However, if you are trying to turn a muddy water hole into potable water, it does.
The article doesn't say how much waste water would be needed to de-salinize a given volume of H20, but if the water flows through with considerably less force than a traditional RO unit maybe there will be less waste water. This could be more important than the energy savings. A good comercial RO filter produces roughly 1 gallon of waste water for every gallon of potable water, and most home units produce two or more.
Where is your antennae located? Several years ago when I was a grad student in engineering I was working with multiple GPS receivers to calculate attitude information about an aircraft. My test apparatus was a PVC "airplane" on the roof of the engineering building, and most of the time I could see 10 or 11 sattelites at once, and occasionally could see 12, which I understood to be the maximum that could be in view at any one time from the surface of the earth. Also, IIRC the sattelites were numbered 1 thru 30; so at that time there were more than 24 sattelites, although I can't be certain how many were active at any one time. I don't ever recall having less than eight sattelites in view; of course there are no mountains in Kansas to block the horizon. I don't know what your application is, but if you can elevate your antennae above the ground clutter; six sattelites 100% of the time should be easy.
I had similar problems trying to get Totem working when I installed Suse 9.3. In the end I installed Kaffeine and everything worked fine; even Windows media files. I'm not saying Suse doesn't need improvement in the multimedia area; it definately does. I just thought I'd offer an alternative that worked well for me.
Then maybe there shouldn't be sattelite TV. When companies have to pass legislation to gurantee a profit, then they have a flawed business plan. No one needs satellite TV, and my tax dollars shouldn't be used to support it. If they can make a profit by using the public airways; great. If not, too damned bad. Not that Direct TV is the first or only company to legislate profits for themselves, it's just that this case really annoyed me.
Everyone is commenting on the damages and how absurd they are, which I won't argue against. However, what I would like to know is how can I "steal" something that is already in my house? Direct TV, or anyone else for that matter, can broadcast signals into my home, and yet I'm not allowed to manipulate those signals. What a load of crap. Imagine if I had to buy a separate brand of radio for each radio station, or a different TV for each television network. Now imagine going to jail and being fined for building you own radio. Why should Direct TV broadcasts be any different than radio or television signals? If you broadcast something over the public airways, then it should be just that: public. So much for living in a free country.
Depends on what you are doing. I used to use a 2-D CAD system with gestures (they were called strokes back then), and it was great. The reason they were so useful is I could issue a command for a particular entity on the screen by just using the mouse. For example, I could start a gesture at a line and turn it into a construction line, or delete it, or drag it somewhere. Without gestures you have to first highlight things, and then either go click on an icon or issue keyboard commands. I've never tried to use them for OS or browser commands, but for a CAD system they are hard to beat.
My boss contacted APC about a couple of our units that were on the list. They are sending us new ones, along with a pre-paid shipping coupon (or whatever you call those things) to return the faulty ones.
Not to mention that the point of aim is not the same as the point of contact. Most people would see the laser dot, or whatever it is, and aim directly at it. Unless you are shooting perpendicular to the rail, the ball will not contact the rail at the point you are aiming at. Experienced pool players compensate for this automatically due to practice, but most novices don't quite understand.
You're assuming that to get the energy out of gasoline or hydrogen you have to burn it. When you do that most of the energy is lost to heat. Heat engines have very limited efficiencies. Batteries may be underpowered, but the power they produce is almost all usable. Fuell cells offer the best of both worlds. You get the energy density of hydrogen , gasoline, alchol, etc.; but in a usefuel form: electricity. Not to mention the simplicity of an electric motor compared to an internal (or external) combustion engine. Batteries may be a dead end, but electric vehicles certainly are not.
The problem is quantity. Both harvesting the crop and converting it to fuel require energy. Assuming your using biodiesel for both of these processes, you have very little fuel left over. I'm not saying it is a bad idea, on the contrary; but there is no way biodiesel can supply our insatiable appetite for gasoline. Besides, most parts of the world can't grow enough crops for food, let alone fuel.
