When I read the first story about him a couple weeks ago I was surprised to see him self medicating himself with antibiotics.
This is dangerous because doctors always make it a point to tell you not to overdo it with antibiotics and once you decide to take one, run it through its full course and take the full dosage for as long as they tell you to. It's a bad idea to take them only until you "feel" better and then stop, because it gives the infection a chance to grow back, only this time it will be more resistant to that antibiotic.
By doing things half-assed and delaying getting REAL help, he's making the problem worse.
I hope he finally gets the help he needs and gets over this illness, and I'm sure he learned what not to do.
Corporate money in the federal government is a major problem. It enables huge corporations to extend their money grubbing wishes into federal law. This is a major conflict of interest and borders on corruption, but I'm sure the first thing they did was lobby the government to declare that this is not corruption.
When a corporation is able to use its money to lobby the federal government to enact a law which in turn forces taxpayers to foot the bill for a corporate wish, something is seriously wrong.
Can you imagine how much more pure government would be if lobbyist money was kept out of the politicians' hands?
Congratulations to the ESA. This landing shows that we're a world leader in the exploration of space, and highlights the prestige and technologic prowess of our space agency. I think every nation on Earth can recognise the bravery of our astronauts and the epic accomplishment they have achieved. Feats such as this prove that with ambition, determination, and the world's most brilliant scientists, we can achieve great things. This is truly a wonderful day for Europe, the ESA and the human race as a whole.
Edit: I've just been informed that this is old news, from the USA, back in 1969. This was nothing more than a publicity stunt and highlights the USA's careless expenditure of money at the expense of the rest of the world. I think every nation on Earth can recognise the reckless abandon in which NASA acted, with no regard for their astronaut's lives. Stunts such as this prove that the USA has ambitions to control the Moon, and that its space program employs typical idiotic gung-ho Americans. This was truly a sad day for the USA, NASA, and the human race as a whole.
I think more useful things would be banning the use of cell phones while driving, putting on makeup while driving, eating while driving, etc.
I enjoy driving. And when I'm driving, I'm driving and not doing anything else. If you took away my ability to drive the 1+ hour daily commute to work, I'd get very bored and wouldn't be able to take the commute.
I think having an autopilot would be good, but it should be optional to use. I don't get enjoyment telling other people what to do, all I ask is that they don't tell me what to do.
And no low income person should pay ANY type of tax... In a capitalist system like ours, the top 50% should be able to pay all taxes for everything. After all, they have like 85% of the wealth.
The problem with that is that the idea, by design, would encourage a further separation of the classes, or even a secession. It would help destroy the balance of power in the country (and it's bad enough already).
Think about it, the rich feel elite enough as it is, if they're the ones that paid all the taxes, what would they need the lower classes for? They'd look at everyone else as dead weight, a burden on their backs. They'd be able to abuse their power even more than they do now and point to the fact that they bankroll *everything* in the country, and that they should have more voting power than the poor majority who don't pay for anything.
I notice that every step of the way, the government finds an incremental way to gain legal power over the people that are supposed to be running the show. And each time they do it, they make sure not to cause too much of an uproar. After people get used to it, they take a little bit more.
Of course you'll get the people who always support the government no matter what they do, so they'll concoct a reason to believe that they're helping us.

As for this law, I think installing GPS in the cars would be a trojan horse of sorts. At first they'll market it like the reason it's there is to help you or to help with emissions monitoring, but long range goals are predictable and it's only a matter of time before they start monitoring your speed with it and sending you tickets in the mail for speeding in the Nevada desert.
The submitter's hysterical comments show an obvious distaste for this decision by TiVo, but his statement, "although it might help them in the short run it will most certainly backfire in the long run," displays a profound sense of arrogance; he knew about this for about 10 minutes before drawing a conclusion based on nothing more than gut, while TiVo Inc., has clearly thought about these issues and decided they were a net benenfit
You can't really go by that, either. You can't trust that the decisions that companies make will be prudent ones. There might not be an acceptable answer to the problem they're in. Enron decided that the actions it took were the right actions for the company. SCO decided that suing everybody was the right action for it. A utility company in Montana decided that the best thing it could do is sell off its assets and become an internet provider in the dot com boom. It dot bombed.
Companies still go out of business, there isn't always an easy answer that gets them out of the hole that they're in. Sometimes the only hope left is to try something drastic.
My point is that the company does probably know something that we don't, but you can't always expect good news out of it. Maybe the company knows it's in trouble and it has to do something out of desperation. As an example, a Hobby shop near my house suddenly changed into an arcade which seemed very strange to me. A month later it was out of business. I don't think changing to an arcade caused it to go out of business, I think they knew they were already in trouble and they had to take drastic measures to get some revenue. That didn't work and they went under.
A company that is stable and profitable doesn't need to make drastic changes to its business model. Once you see big changes like this, a shakeup is in progress and they're acting desperate to survive.
You've all put my life in danger by allowing him to be re-elected. And I'm not sure I'll ever forgive your nation for that; you've certainally all completely lost my respect for a very long time. And this is from someone who used to love the US and visit anually. I still respect what the US used to stand for, I'm genuinely worried about what it's become. I won't be back.
I didn't allow him to get re-elected, I voted for Kerry. What amazes me is some of the most politically motivated people in this country don't vote, they just attend marches and complain.
Right now I'm just along for the ride in an out of control car. I don't need need people taking cheap shots at me for something that's beyond my control. I did everything I could and was outnumbered.
So therefore you are a part of my problem. As I said, you guys lost a lot of respect from me on Nov 14th, and I doubt I'm alone in these feelings. America is broken just now.
We're not part of your problem, WE voted for Kerry. The people who voted for Bush are part of your problem. And what happened on November 14th? That was 3 days ago.
If you're going to bash and blame the people who agree with you, you're still making enemies out of them. Of course they're going to fight against you. The people who voted for Bush aren't declaring me their enemy but you are. Whose side do you think I'll take- the one who is attacking me or the one that isn't?
If you want to win a battle you don't create more enemies. It's a basic concept, but Bush doesn't understand it and neither do you. You're no better than he is.
It's amazing the lengths people will go to show that the USA can or has been beaten. Even if the USA won, they'll concoct a reasoning that shows that they really lost.
I think there's an irrational hatred of the USA in general which causes people to want the US to fail. I don't waste my time bashing other countries highlighting all their failures, I want them to succeed. But I also want things to be kept in perspective and not sensationalized or overlooked. Saying that a country "can" do something that another country already has done is cheap talk. Let's keep it real- until they have, they haven't.
Your reasoning was pretty good, but it still was a stretch... it seemed like you were really reaching for something. Neither the USA, Russia, or China are going to build a "castle" on the Moon or Mars and defend it against exploration by another country. Space exploration is usually an area where countries help each other out even if they're enemies in another regard.
It is important to push emotions aside and keep things in perspective. Even if you don't like someone you should still be objective. Spinning the truth to make them sound like a failure only uncovers your bias against them.
I've seen strengths of 65-120 GPa listed for the minimum required strength for a space elevator cable. Spider silk is around 1.3 Gpa, so it's not even close to being as strong as what's needed.
Spider silk is about as strong as Nylon, both of which are many times as strong as steel for the same weight.
They're making this sound like it's a step towards achieving their goal, but really what they did today wasn't a stretch of the imagination like the final goal is.
If I claimed that I can jump to the Moon, you'd look at me like I was crazy, because the laws of physics would be completely in opposition to my claim (for example bones would shatter long before you could exert the force to jump even 50 feet). Now if I showed you that I could jump 3 feet, would that really convince you that I'm making progress towards my claim of jumping to the Moon?
To get back to this space elevator idea, climbing 260 feet is no big deal at all using cables that we have today. It's simple work. However, making a cable that is 30,000+ miles and able to support its own weight plus the weight of the payload is impossible with these cables. They'd need a material that doesn't yet exist.
The real hurdle in this project is not making the robot climb the short conventional cables that are readily available, the real hurdle is getting a hold of cables of unbelievable strength made of a substance that doesn't yet exist.
If you're upset about this then you are doing something that is illegal. Face it
So if I buy a DVD from the store and want to fast forward past the advertisements before the movie, that means I stole it?
I am able to fast forward past advertisements on the VHS tapes I have, but on DVD's they are taking advantage of the lock feature to prevent you from fast forwarding past the advertisements. With this bill, not only don't we have a choice available to skip the ads, but it will be ILLEGAL to skip the ads.
Seems like an abuse of power to me, it shows where the money that is filling politicians' pockets is coming from.
"After hearing the news that the ESA's slow ion-powered probe has entered Moon orbit after a record-long 13 month voyage, NASA has announced that it will launch an even slower probe that propels itself by gliding on a trail of its own mucous."
I'm sure they can get this beam to work, but it won't be long for countries to coat their missiles with a coating that reflects the wavelength that this laser uses. That would increase the amount of time it takes to heat up the missile. Also rotating the missile will do a good job of spreading out the heating. Whereas a green missile might be destroyed in 5 seconds, a gold or silver missile might take 50 seconds, and a rotating gold or silver missile might take 3 minutes. By then the opportunity to kill the missile has passed.
I think the real app for this would be an assassination beam to kill high profile targets on the ground. If you suspect that your enemy is in a car on the ground, zap him. He can't hide from a laser from above. It would also work extremely well against enemy aircraft.
"Just days after news that AOL will be breaking up into 4 business units, AOL is telling existing broadband customers in 9 Southern states to find a new carrier. This news comes after AOL stopped selling broadband services earlier this year. AOL plans a similar phase out of existing broadband customers for the rest of the country over the next year."
The aircraft is retired from the airforce and all information about the aircraft itself has been declassified for years.
From the years of secrecy, the aura of secrecy still exists even after it was declassified. In reality you can look up all data about it and even buy the Dash-1.
Its performance is limited by operating constraints that would be considered common sense to anyone used to working with such aircraft. The SR-71 is a great design, but it's not magic.
It's no longer a secret plane and you can now scour over all the information you want about it. Remember, this is early 1960's US technology, I'm sure we have a better "weather balloon" now.
The performance characteristics of the blackbird were declassified years ago. You can even buy the Dash-1 (operating manual) for it which tells you all the details about it.
If you do a search on Usenet, look up posts by Mary Shafer, who works at the Dryden flight research center for NASA. She has tons of info about it, since she worked with it. After the Air Force stopped flying the SR-71, NASA continued to use them for flight research.
The flight characteristics are now public, and nothing about the aircraft itself is still classified. The only thing still classified is information about the missions it flew. That's understandable since legally it couldn't fly over enemy territory, it had to fly around the fringes and shoot photos from the side, but they said the same thing about the U2 until the Soviets produced the wreckage of one shot down over their territory.
About its speed, the upper limit is Mach 3.2-3.3. The speed is limited by the engine inlet temperature and bad things would happen if you tried to push it faster. In addition, due to the design of the aircraft, the shock cone generated by the nose would begin to impinge on the wings a little over that speed. As you can imagine, the airframe wouldn't hold up very long if that happened.
To sum it up, the aircraft was engineered from the ground up to be a Mach 3 aircraft. It can cruise at Mach 3 but its top speed is not much higher. Other stories and rumors you've heard didn't come from anyone who flew or had any knowledge of the aircraft and are just fantasy.
There are some pretty good conversations about the Blackbird existing on usenet by people who have flown them.
I remember reading how they flew the aircraft by engine inlet temperature and not Mach number, since the limiting factor in their speed was the engine inlet temperature. They could keep accelerating until that max temperature was reached, and that varied with atmospheric conditions. Basically Mach 3.3-3.3 is the max speed it could ever safely go.
I've read plenty of stories from Blackbird pilots on usenet, and it sounds like getting a lock on a Blackbird is not hard at all. You can track satellites by radar, too, but you'll have a hell of a time trying to shoot one down.
The problem is getting your missile to reach it. By the time you get a lock and the missile is fired, the Blackbird has already put quite some distance on you. You need to remember that it flies at 80-100,000 feet in altitude, so the missile will have to climb about 30-40,000 feet vertical just to be at the same level. Also, most air-air missiles have a top speed of Mach 3-4. Basically the missile won't catch up to it very fast, and it will run out of fuel before it ever does.
I think the common stat that I've heard is that the Blackbird was fired at over 3,000 times, but was never hit.
