Then you have no idea how the space elevator works.
It's not anchored (structually) to the surface of the Earth. It's connected, but that's only to keep the lower end from moving around do to the effect of the atmosphere (wind)
The anchor is a point in geo-synch orbit, the midpoint of the full length of the elevator. The lower terminus is at Earth's surface, but its upper end is as far away from the midpoint as the lower end is (think equal mass). The whole thing actually orbits the Earth just like a geo-sync satellite.
What the GP means is that in its 'Power Generating Mode' (essentially idling) it produces enough kw to power an ion drive.
The article discusses a flight regime in which the ship leaves orbit under full power on the NTR, then throttles back to 'idle', switches to an ion drive for the majority of the flight, and perhaps switching back to 'full' at the destination when entering orbit. The latter may not be needed if you adjust the point at which you turnover and decelerate constantly using the ion drive for a longer period of time.
Yes, but news isn't just writing the facts about current events. It's also writing about other people and what they've said. Their bias is your subject.
Your bias, their bias, someone elses bias. It's always there.
You know, until we have our news reported by computers and robots, every piece of information is going to have some bias attatched to it.
It may not even be the bias the reporter wants. What word or phrase they use in their story may have a signifigantly different connotation to different viewers.
So, you can't escape bias. But you can compensate for it. I noticed something years ago, while standing in lines at the grocery store... Weekly World News, The Enquirer, and other freaky magazines... All had outlandish tales on the cover. But in the few instances where they had the same story, the story was actually true (mostly related to foible and escapades of the Hollywood folks).
That got me into the habbit of look for the same story through different outlets. If one approaches a news outlet with an open mind, one can generally see the bias. So I then look for the same story from an outlet with the opposing bias. The 'real' truth is somewhere in the middle.
I agree, there shouldn't be a bias at all. But, they're only human, and their perceptions and experiences are different than yours, and will color everything they see and report.
I would just like the new outlets to be upfront and honest about it, rather than pretend to achieve the impossible goal of perfect impartiality.
6)Roughly what percent of your music collection comes from d/l copies of media you USED to have (broken tapes, scratched CDs, etc.)
7)Roughly what percent of your music collection comes from d/l copies of media that isn't available for purchase. (old releases, or international releases not available domestically)
It's a compromise set forth by the founding fathers.
Without the Electoral college, the rural states would be at the mercy of the populated states. New York and California could effectively dictate to the rest of the nation.
What's good for California is not nessecarily good for South Dakota.
It's not perfect, but it does the job.
The 'one voter, one vote' theory only works when all the states have like populations.
It's not that the Shuttle's a waste, it's that someone else already does more efficiently the same task the Shuttle is supposed to do.
As a former US Submariner, it really pains me to admit this, but in this arena the Russians have us beat.
Of course, this presumes that we'll have access to their vehicles. If something comes up that we don't, then we need the Shuttle, or something compareable.
Wikipedia is hardly an authority on the Boy Scouts of America. Try reading the Boy Scout Handbook. The origins of the of the scouts are in the first chapters.
And the gentleman that envisoned the boy scouts drew from his experiences in the British Army, so that's hardly surprising. But the BSA distanced itself from military trappings in the 1920's.
Scouts have nothing to do with the military, or military structure.
Cub and Boy scouts were organized more like an indian tribe than an army platoon.
The patches only depicted acheivements within scouting, not any kind of rank. Someone with fewer patches was not obligated to follow the orders of someone with more patches.
At the local Jamboree we would have representatives of the armed forces, national and coast guard. as well as fire, police, and paramedic units.
And the grandparent is correct. Paintball, or any kind wargame scenario was strongly frowned upon. We were geard towards environmental conservation and stewardship, plus health and personal safety.
They may take DC training, and every sailor has taken basic firefighting and flood control in boot camp.
But on every surface combatant, there is a dedicated damage control division, who's personal are on the ship for the specific purpose to fight fires and stop leaks, and maintain the systems/tools to do just that.
There is no comparable division on submarines. Every person on board wears 2 or 3 hats. Their rating, supporting the maintainence for the equipment required for their rating, and damage control.
I don't know about cooking, except there's moral benefit, and it may be easier (from a logistic view) to store just the basic ingredients and go from there.
Cleaning, on the other hand, and has a definate benefit towards maintainence and ships safety. Debris on a flight deck can get sucked into a turbine and wreck a plane. Dust, dirt, lint, fuzz can really hurt when it comes to controlling a fire.
Your 20% is nearly dead on for surface ships. It may even be higher for larger ships, like carriers.
But for submarine crews (USN) we have no standing damage control division. We just don't have the space for dedicated personnel. A large art of the rigorous submarine qualification that every crewmember is required to achieve involves damage control.
Well, even the old WWII fleet boats had a 7/8" hull. As to the exact thickness of the current nuclear boats. Well, I know the answer, but I think it's still classified. I'll find out for sure and let you know.
But thickness = weight, which, on a submarine, HAS to be kept as light as possible to maintain bouyancy.
Example, the 688 (Los Angeles) class of SSNs had to have its hull thickness dropped by over a 1/3 to save weight. Just like an airplane, weight and size are constantly being juggled.
G forces are one thing. But the shuttle only has to deal with a pressure differential of 1 atmosphere. The current generation of nuclear powered submarines has to deal with pressures at least 60 times greater. Plus the corrosive action of saltwater. Vibration is an issue as well. The SSTG (ship's service turbo-generators) spin at well over 20,000 RPM, with a finely machined series of reduction gears dropping it to about 100 RPM.
Not only do you have to navigate a submarine in the environment, you have to fight there, too. Over-engineering and backups upon backups, plus the ability to perform most repairs at sea...
Sure, the golly-gee, whiz-bang, push button factor is higher on the shuttle. But for just sheer competence and excellence of engineering, the nuclear submarine is a far more complex machine than the space shuttle
Why not a copy protection scheme that gives you unlimited copies, but a) requires the master, and b) can only make one copy at a time (preventing the use of multi-burner arrays)?
Joe Schmo can make copies for his car/boat/pc/mp3 player, but none of those can be distributed any further. And the large pirate groups can't just crank out unlimited copies from the master, not without investing huge amounts of time, limiting their profits.
(the really professional groups use presses, stamping their own CDs, not burning them. As far as I know, there's no protection against that tactic, once you have the physical media)
You can use your purchased CD or d/l tracks as many times as you want. But you're prevented from widespread distribution to others. And hopefully, it's a transparent-to-the-user scheme.
I'm getting ready to do something like this for my fiance... our houses are only 5 miles apart, and no desire to set her up with DSL and the associated contract since she'll be moving in here in a few months anyhow. Tie this into my DSL here, then point a pringle's can at her house, then her laptop with a wi-fi card can piggy-back onto my connection
At first, I thought he had a valid complaint, but then as he goes through his shopping list of ills, he generalizes and skips over potential fixes any tech worth his salt would pursue. (and these are quite simple enough for any reasonably intelligent user to perform. I have instructed my own father over a the telephone, how to perform these items)
1) I have an IBM Thinkpad A22m, purchased in November 2001. It came with Win2k.
Only once have I performed a system reinstall (3 weeks ago or so) to free up hard drive space from numerous programs, and not because of any issues with the operating system.
In the 2 1/2 years I've used this incarnation of Win2K, I have applied Critical Updates from MS as they were released. I also ran McAfee 6.0 (retail), and IE 6 was the browser of choice.
Until this last fall, I did not run any type of popup blocker or spyware utility.
Prior to starting the system reinstall, I visited the Windows Update site, and used thier tool to determine what updates I had installed. Each item that I no longer had the files for, I d/l again, and burnt all the hotfixes and updates to a CD.
I did the same thing for the most recent drivers for this laptop, as well as for all the peripherals I had.
Then I compiled a list of utils that I find invaluable (Avant Browser, Adaware, Spybot, SpywareBlaster, and other goodies) and put on a CD.
Now, I have the orginal Win2K install CD for the laptop, a CD with all the drivers, a CD with the hotfixes / SP4 and handy utils. (plus CDs for the original applications,such as MS Office, Photoshop, etc)
The whole idea is to not put the machine on the net until it's relatively secure.
So now, I format the drive, and boot from the OEM Win2k CD. 45 mins or so for the install, then another 45 to install SP4 and the hotfixes (using MSs qpatch util, I don't have to reboot the machine until after all the hotfixes are installed)
At this time I turn off Windows Messenger Service, and finish installing my utils. That takes about another 30 mins.
Now, the machine is secure from pop-ups, spyware, viruses, and most MS OS-based exploits.
Time, about 2 hours. It takes me longer than that to setup and patch a RedHat 9 machine.
SpywareBlaster does NOT detect ot REMOVE spyware, that's not its job.
It's an immunization tool, to keep known spyware from being installed.
A lot of programs have similar names, so the program to which you're referring, and the actual program called SpywareBlaster from Javacool may not be the same program
Good practice, btu I don't see that it would stop the spread of Sasser.
It starts at port 1068, and works it's way upwards. At somepoint, it'll probably find an open port that's not tied to another process. Unless you have it so locked down, that EVERY port above 1024 is blocked, or restricted in some way.
With the various chat and P2P clients out there, that's tough to do.
