if that ever happens then we will all have to protect our DNA (Hair, skin, spit, etc.) because loss of control of your DNA to a criminal spells guilty in court.
I really worry more about the method of closure more than anything. Anybody ever seen the smoke coming off of a welding electrode? Can't be good for any media. First if you decide on any media such as DVD or CD then definitely use vacuum seal bags with some kind of internal frame/box to keep the vacuum on the bag from warping the media (if it needs to spin when read)
Otherwise make sure the welder understands that ~no~ gas from the welding process can enter the protected enclosure. Filling the enclosure with nitrogen (good) or helium (best) would be advisable.
Welded??? How the heck are the future pic viewers supposed to open the vessel??? What if they whip out the old cutting torch and slice it right through the middle with nice big lumps of slag dropping on your oh so carefully preserved media??
Think of a better way of enclosing such as a vacuum sealed box inside a sealed 30 gallon drum inside a sealed 55 gallon drum sealed in concrete.
Ha! You prove the point in the article. If you don't believe you are a "denier" your alternate viewpoint is "crapola" and the issue is "not up for debate"....Think about it, you sound like the Churches response to Galileo's heliocentrism.
People are free to act in a law abiding manner, there is no freedom to mug people.
This technology will have no effect on peoples freedoms. If two people are thought to have been in a fight and neither one files a complaint then it was a waste of police time. No problem for the freedom loving boxers out there. If there was to be police abuse such as issuing a disturbing the peace ticket or whatever then how long would it be before flash mobs appeared in front of a hundred cameras and all had staged mock fights just to set off the sensors. How many improvised "plays" would happen in front of the cameras.
I just have to wonder what activity would a law abiding citizen have to quit if they were watched by a video camera?
I can see some interesting things happening if the cameras were public! Less cheating on spouses maybe.
I think part of my opinion comes from growing up in a very small town. Where I knew every resident by sight and could name most of their names, and their kids and parents too. They knew me also, and quite often my misdeeds of the night were known to my parents before I made it home.
Some cool benefits arise out of such a setting, like child molesters don't live there, they prefer the anonominity of the city. But we had to drive 35 miles to buy beer:/
Did a bit of research a while back and found out that a modern 1 GigaWatt coal fired power plant produces about 60,000 pounds of radioactive waste per year (mostly thorium) that is in the fly ash (the remains of burnt coal). The fly ash is then sold and used in roadbeds and concrete I think. The typical nuclear power plant releases something on the order of a few kilograms of radioactive material to the enviroment each year. Naturally the nuclear power plants also have radioactive waste that is removed and stored properly.
I think of that when I drive into my local Wal-Mart, where I saw several trailer loads of fly ash being put down on the parking lot.
60,000 lbs/year......in roadbeds.....in my neighborhood.....Do the enviromentalists really give a crap about the envronment?

Oh Geez, you think IT is problem job? Try being a salesman on the road 50 weeks a year, or a field engineer rolling out a multi-year project in China, or even field technicians for Fortune 500's that do multi-year rollouts, construction (from engineers to dump truck drivers) the list is very long and IT is not even close to being the worst. Get over it, get your life in order, pick which is more important to you, your work or your kids.
I have been playing this game for a couple of years and I still have not done everything in the game. The content is very deep and Teppy (the lead developer) does a great job of keeping things interesting. The best thing about this game is there is no up front cost, you get to download and try it out for 24 hours of in game time for free. Very cool.
I don't know why you can't. If I were a terrorist I would. If I was discussing a business deal that was valuable enough that I would worry about foreign intelligence services picking up on it and passing my conversation on to competitors, I would find a way. What does it take a crypto license or something? VOIP over a VPN sounds like what I would do. Looking at the L3 web site http://www.l-3com.com/cs-east/ia/ste/ie_ia_ste_faq .shtml I don't see any licensing issues etc listed in the FAQ. They do have a direct sales number:)
I wonder how the NSA will know that it is an American making the call when you call Bangkok from London? I don't think you are correct. Your right to privacy is not absolute, there are legal wiretaps etc. Not to mention many other presidents have done exactly the same thing as Bush. This is not a big deal. If the president has to authorize a wiretap I am all for it. It means that if it is not a matter of national security then he will not be wasting his time on it.
I people are missing the fact that these calls were to a foreign country. Why would anyone expect calls, that can be routed through other countries, have the same level of privacy as calling your neighbor? The NSA or the FBI could just work with the British equivalent of the NSA to intercept these calls legally. When you make an international call, it is not private and you can have no real expectation of privacy. If the signal bounces across a satellite link is it encrypted? I doubt it. If it gets switched between fibers in Diego Garcia what are their laws?
I would think about the faculty point of view as well. I would think that most of the engineering staff are going to have their resume out very shortly, that might mean the last few semesters are very understaffed or the courses may be canceled due to a lack of teachers. Transfer now.
I subscribed to SA until I read that editorial. I never liked the political commentary bashing the administration, when other administrations had raped various science budgets and projects but didn't seem to receive the same scorn. But I put up with it.
After the April issue came out and the editors made known their disdain of their customers through the sarcasm of their little April Fools joke, I decided I will not support them with my dollars anymore.
Give me science news not a political biased view of science. I don't ask them to start denouncing proven science like evolution, but I do think they could increase their sales if they just stuck to the science.
I have been a technician for 19 years and have learned that the most important part of earning respect is in making sure your client knows how hard you are working for them.
This dawned on me one day as a client mentioned that one of my techs did a fantastic job repairing a piece of equipment. I had been riding this guy for weeks because he was not doing basic repair stuff like vacuuming it out. He just kept ordering parts and had his head inside the machine 3-4 hours a day. What the lady that owned the machine cared about was his doggedness about coming in every day and working on it. Muttering about the insanity of the manufacturer, sweating, cursing under his breath etc. He really looked like he was doing his best. That is the key.
I work with radio equipment, 911 dispatch type stuff, and one day got called in on a nasty interference problem. I took a look at the environment and reviewed the complaints and because I knew intimatly the environment, I came up with a solution that took 10 minutes and solved the problem. I could have easily spent several days chasing the problem had I not had so much experience in the area. After fixing the problem and feeling quite exhuberant about such a subtle solution (I moved an antenna a mere 3 feet which blocked interference coming from 2 miles away) I realized that the manager who called me would not understand what I did and would not appreciate it. Obviously since I fixed it in 10 minutes it must have been easy and he was not at all happy that he had to pay for a 1 hour service call, when I had only been there 30 or so minutes.
Lesson learned.
I have never dogged it on a service call but I have sent much less experienced techs on calls I knew would take a long time if they didn't know exactly what was up:) Customers love us. An outgoing communications manager for a 911 dispatch center recently introduced me to his replacement as "the guy who saves your ass".
You get no respect when you walk in and punch a few buttons and the problem goes away. You get respect when you pull the guys ass out of the fire just as he is falling in.
You need to provide more information to get a coherent answer. You mention a range of 100's of meters, are the endpoints fixed with line of sight between them for antennas or are you going through concrete and steel walls? What bandwidth do you need? Is this an intermittent signal like polling for data or a continous stream of audio? These questions have implications on the frequency, power, bandwidth and modulation scheme of the signal generated. Give more info on the application and why you can't have "hackers". Does this mean you can't have someone steal your content as it passes over the air or does it mean that you can't have someone spoof your data or are you talking about interference problems causing downtime? All are important questions. What is the cost involved with link downtime? This is important in RF as well.
Not to mention that maps of high value targets that should be protected would be called for by any reasonable military campaign.
This war was not about oil, it was about a show of force to the world. That America will not lie down in the face of terrorist demands, that we as Americans are not going to put up with power mad dictators. The United Nations is now officially a joke. If they as a group had actually done something about Saddam Hussein rather than pass silly resolutions with nothing to back them up. If they had actually required that Saddam allow the weapons inspectors full and unfettered access, the war would never have happened. But letting Saddam kick the inspectors out every so often, allowing them to actually lock up American warplanes with fire control radar, the United Nations caused the war. Had there been stiff penalties like the cessation of "oil for food" (what a joke, more like "oil for food and kickbacks") and military strikes for every breach of the United Nations resolutions, then there would be no need for war.
If you want to call CO2 pollution that is fine, but understand that the only way to reduce CO2 emissions from a coal fired plant is to increase effciency, you can scrub out the sulphur, burn the carbon monoxide, catch the fly ash etc. but you can't do anything about CO2 except make the plant more effciently burn the carbon (coal)for a desired power output. There is talk about liquifying the CO2 and burying it but that is in the future.
If you want the numbers then here ya go:
Kyoto would save an estimated 483 million tons per year
What the US will add 275 by 2012 India will add 486 And China will add 1926 million tons per year
These numbers are based on India and China using state of the art plants that are 10% more effcient than todays US fleet of power plants
I would be all for Kyoto if it actually made a difference, but it doesn't. The estimated effect of the Kyoto treaty is a reduction in global warming by 0.1 degree C over 40 years and 0.2 C by 2100.
How much are we paying for that 0.1 Degree? Have you seen the price tag attached to the Kyoto treaty? They don't give you price tags, but you get a nice warm and fuzzy from taking a stand against global warming.
The only real solution will come from alternate energy sources such as nuclear reactors. And please don't talk about radioactive waste, The average 1 Gigawatt coal fired power plant releases about 60,000 pounds of radioactives per year compared to a nuclear plants 3 pounds. Nuclear plants are required to actually do something about the waste where coal fired plants just spread it around on roadways and construction projects in the form of fly ash.
I wish people would actually read up on a subject before lending support to something as vague as global warming
China is on track to build 562 new coal fired plants in the next 8 years. India is looking at building 213 plants. The US 72...The US does not matter in this equation, talk about China and India. Any gains in CO2 emmissions are buried by 3rd world increases.
Heh, of course there are other methods to guide stuff, GPS is just quite a bit cheaper, more accurate, and easier to obtain.
And as for ICBMs, I am sure you understand that if an enemy can make one, they are also using inertial guidance etc. so GPS isn't in that equation.
As for GPS spoofing, The russians (Moscow-based Aviaconversiya Ltd.) sell GPS spoofing gear and have no qualms about selling it to both sides of a conflict.
Turning the gps signal off should not be a problem at all since any nav system using gps will detect when there is a loss of signal.
Can you name a nav system that uses gps only that has humans on board and no manual backup...like a pilot?
All that aside what you seem to be saying is that if the US military detects a plane or cruise missile that presents a threat to the population that they should not be allowed to turn off gps over the area where the threat is (yes they can turn it off in one area only) to try and minimize the damage because an innocent might be killed elsewhere. I think the innocents in the flight path would be asking you "what about us?".
Some key uses in the mind of the enemy might include using gps guided unmanned small aircraft loaded with explosives for precision strikes on various targets. Letting the public know that GPS can't always be trusted blindly might help keep merchant sailors on the bridge at sea so they actually look out for hazards to navigation! Think what would happen if a hacker decided to spoof the satellite signal and send those gps dependant ships and planes crashing into stuff.
I use high level software tools at work (rf coverage plotting) that completely gloss over the details and make the job very nice and easy...I love them. The problem is that when I try to teach someone else to use them they are so sorely lacking in the low level fundamental skills (the skills learned the "hard way") that they can come up with bizarre solutions and not even realize they are incorrect. My point is that if a student learns and completely understands the problem then software tools and graphing calculators are great for doing a bunch of the problems on a day to day basis. But in the learning phase, learning to do it the "hard way" seems to make people understand the problem better and retain the knowledge for longer. When you understand what the software is doing you are much more likely to know when the software is giving a wrong answer. (or your inputs were hosed)
In class if you get an answer wrong it is 10 points off, if I get an answer wrong at work it means I lose a bid or worse, win the bid and have to do the job for below cost.
I must have been unclear about my problems with the technology. I don't have any problems with it, the other students did. They were asking questions about how to do this and that in class and taking up class time. Time I paid for. I was especially irritated when an entire class was taken up with "calculator training" then the instructor announced a quiz next class over the material we should have covered.
As for your questions, I am neither teacher nor student now. I took some classes about 5 years ago at the local community college as a refresher. My teacher had a good grasp on the technology, it was the students who didn't. I paid for a class about math not calculator use. The local high schools use casio (I believe) calculators and the teacher said a TI was required, so many of the students had problems with entering functions etc.
As for augmenting the training I am sure the graphs are pretty and all but I have had several math teachers that did a great job with chalk and that is also within the last 5 years. In fact the quality of teacher was inversely related to the amount of graphing calculator use. (with an admittedly small sample)
I believe that the teacher should be primarily teaching how to think about and solve a problem. Not technology use. You want to use a graphing calculator? Fine by me! Just don't take a math class to learn how to use it.
Exactly!! I find that computers and for that matter graphing calculators waste time in a classroom due to the teacher constantly having to explain how use the thing to the student, taking away from actual teaching. Not to mention different schools requiring different calculators or using different software. I read an article about some MIT (iirc) students who when asked about computer use responded "we're math majors we don't use computers" (paraphrasing, was a long time ago).
I believe that a teacher given chalk and chalkboard can teach math quite well, possibly even imparting some visualization skills that might not be learned with computer generated graphs at everyone's fingertips.
I doubt that the thermal inertia of the earth's surface would allow a 1.3 degree change in temperature for just a millisecond. I also don't think that a cloud could hang over just one area for 3 years from a single event. When a USGS scientist says that the earths surface cooled, they mean the entire earth not a 1" square patch somewhere in the world. As for a control area I would assume they used the years preceding and the years following as data to compare against. Otherwise using your theory of the data being invalid, how could there possibly be global warming...there is no control area (your words).

Otherwise make sure the welder understands that ~no~ gas from the welding process can enter the protected enclosure. Filling the enclosure with nitrogen (good) or helium (best) would be advisable.

The local high schools use casio (I believe) calculators and the teacher said a TI was required, so many of the students had problems with entering functions etc.
As for augmenting the training I am sure the graphs are pretty and all but I have had several math teachers that did a great job with chalk and that is also within the last 5 years. In fact the quality of teacher was inversely related to the amount of graphing calculator use. (with an admittedly small sample)
I believe that the teacher should be primarily teaching how to think about and solve a problem. Not technology use. You want to use a graphing calculator? Fine by me! Just don't take a math class to learn how to use it.
Exactly!! I find that computers and for that matter graphing calculators waste time in a classroom due to the teacher constantly having to explain how use the thing to the student, taking away from actual teaching. Not to mention different schools requiring different calculators or using different software. I read an article about some MIT (iirc) students who when asked about computer use responded "we're math majors we don't use computers" (paraphrasing, was a long time ago).
I believe that a teacher given chalk and chalkboard can teach math quite well, possibly even imparting some visualization skills that might not be learned with computer generated graphs at everyone's fingertips.
I doubt that the thermal inertia of the earth's surface would allow a 1.3 degree change in temperature for just a millisecond. I also don't think that a cloud could hang over just one area for 3 years from a single event. When a USGS scientist says that the earths surface cooled, they mean the entire earth not a 1" square patch somewhere in the world. As for a control area I would assume they used the years preceding and the years following as data to compare against. Otherwise using your theory of the data being invalid, how could there possibly be global warming...there is no control area (your words).
