Wal-Mart is not going to drop prices to the point where they lose money. Also, recall that Wal-Mart hires illegals (who work for less, helping keep prices low), buys most of their goods from China (where sweatshop and slave labor and government funding and unfair currency rules, etc.) keep prices low. One of Wal-Marts execs has been accused of stealnig 50K from his company, and another exec just quit to go to Microsoft (start of a alliance?). Sure it's cost cutting but is it really ethical? Wal-Mart is NOT a big Teddy Bear!
Most contollers have "day jobs" at NASA as wel. So NASA IS at full staff during a mission and also when the STS is on the ground. Other work is postponed for controller duties, and alternate shifts are worked. Extended 1 days costs NOTHING, the consumables on the STS (food, and fuel cells, and to some extent air) are the limiting factor. Most experiments are automated, but some will require readings to be taken by astronauts, that is why there is a Science Office on board. He/She has that job as thier primary job. In short, I don't think the extra day or the extra spacewalks cost anything. The STS launch is pretty much a fixed cost whether is 1 day or 14 days. As for lost work, they'll just work a few longer hours and get less sleep. Remember you got a 7 person crew and only two did the repairs. I don't think the other 5 sat around and watched!
It's just an extension on the layer shielding idea. Ideally what you want is something that absorbs the rays not just scatters them. If we had the technology to build something like the Monoliths, I suspect we would have invented FTL travel using wormholes so the radiation problems would likely be no big deal as the trip durations would be via an alternate universe or it's equivalent. In fact some suggest that a wormhole trip would be instantaneous, however I still think the time dilation problem would take effect.
One atom at.9c is a LOT of energy, you don't want to be hitting that atom. That's one thing none of the sci-fi writers gets right, how to deal with the space "dust" (atomic Hydrogen and worse) at such relativistic velocities.
You often get bremsstrahlung ("braking radiation") - the single particle is instead replaced with a shower of much more dangerous particles.
Most galactic cosmic rays have energies between 100 MeV (corresponding to a velocity for protons of 43% of the speed of light) and 10 GeV (corresponding to 99.6% of the speed of light). The number of cosmic rays with energies beyond 1 GeV decreases by about a factor of 50 for every factor of 10 increase in energy. Over a wide energy range the number of particles per m2 per steradian per second with energy greater than E (measured in GeV) is given approximately by N(>E) = k(E + 1)-a, where k ~ 5000 per m2 per steradian per second and a ~1.6. The highest energy cosmic rays measured to date have had more than 1020 eV, equivalent to the kinetic energy of a baseball traveling at approximately 100 mph! (So should shielding be wood?;))
Note that 100MeV is about 30X Gamma Ray Energy so even with the loss of energy in the collision (it's not 100% transfer of energy) with the shielding there is a lot of energy left over to cause havoc in the material used as the shielding.
Legal decisions should be CLEAR and understandable by all involved from lawyers to the high-school educated guy running the machines on the floor. IMHO, all the Dave vs Anti-Dave arguments are BECAUSE the NLRB was unclear as it **assumed** everyone understands the Section 7 context when in fact they don't as evidenced by those here who are certainly NOT your avg. workers.
I did read the decison, and I think it could have gone either way. The board is splitting hairs to pretty much avoid making a decision. IMHO, the rule the company has is overbroad in that how do you define "over(ly) friendly" with a co-worker? Dating I can understand, but that rule has been challenged recently and I'm not sure all of this doesn't violate the Constitutional right to assembly for whatever matters you chose (as long as it's not crimal association. I hate it when employers think they OWN the employee. Treat them right and the bonds of loyalty will far exceed that you can specify by rules.
Not to mention the problem (in some designs) of putting ENGINES on the butt end of the SRB. If they want to do this design, take a current STS, yank out the Environmentals, add in the software to remotely fly it back (most of that is there, except landing, the "pilot" is there on a check ride), and to dock it (steal it from Progress if you need to) and you got pretty much the same thing for one HELL of a lot less money. NASA has lost the "common sense" engineering it used to have. Having worked for NASA on three seperate occasions over the last 20ish years I can tell you it is only going to get WORSE. By the way, even though the Prez has supported it NASA has pretty much shelved the idea of a Misson to Mars as they don't think they can do it anywhere close to the budget that they told everyone!
I'm pretty sure there are some in Lower orbits too.
Polar orbits are lower, some sats in the Polar orbits are NOAA/POES and DMSP weather satellites, Landsat and SPOT (remote-sensing satellites). See http://noaasis.noaa.gov/NOAASIS/ml/genlsatl.html
for more info. There are not really "weather" (as we think of it) sats but gather data that is useful in many areas not just meterology.
The EFT is NOT designed to be VERTICALLY load bearing except for Aero loads from launch. It would have to be redesigned as well, but foam shedding wouldn't be a problem anymore. There are serious problems with each option based on re-use of STS technology and equipment. It's jusing FORTY YEAR OLD designs and technologies. For the money we can do a LOT better. People will say there are a lot of "sunk costs" from the STS that the new system wouldn't have, but with all the redesign needed I tend to think there would be a lot of new costs, not the least of which would be launch systems (pad and VAB at too short)
What is absurd is that we as a nation JUST FINISHED designing two launchers using the latest technology that are in rate production and are completely capable of doing not only the LEO lift job but are clearly superior for in-space transport. They have greater performance, equal or better reliability, lower costs and the greatest possible synergies with USAF and commercial missions. They can be readily extended to more than double the Shuttle derived performance and have far fewer bounds on payload volume. They are dismissed by saying that they are not man rated. There is NO SUCH THING as man rated. Given NASA's preferences for man rating there is not an airplane in the world that would be permitted to fly. The whole thing is a red herring. These EELV-derived machines can be made safer than anything NASA is conceiving - and will DEMONSTRATE it by actually flying. Something that is far better than a mass of paper purporting to calculate some theoretical reliability. And somethng NASA will do damn little of given their present architecture.
EXACATLY the discussion I have had with some former colleages at NASA. NASA has a bad case of 1960's disease (cuz that is how far behind the leaders area) and Not Invented Here on top of that. The two SYSTEMS you talk about are PROVEN, and the man-rated thing is crap. They are just as safe as STS, maybe more! With an escape system for the crew (hello..STS doesn't have this now..that stupid pole-bail-out ain't going to cut it) it'll be even better. Plus you got two companies making these things for a PROFIT as well as many International partners (IIRC, the engines on one are actually a Russian design (RD-70?)) willing to join up for the $$$.
I think it goes back to what someone said that NASA has outlived it's day and should go back to Space Science and Aero/Astro reseeach and leave the rockets to those who know them..private industry.
Wish I had Mod points, that's one of the best analysis pieces I have seen in a while. I would tend to think you ARE a Rocket Scientist!! The name (H202- Hydrogen Peroxide) is a giveaway too.
Keep on posting, one day we'll get these dummies at NASA straight:)
Funny! Wish I had Mod points.
Except the TV sats are not in LEO, many of them are geo-stationary at 22,500 miles out, the ISS is around 700 miles. But they could hijack TDRSS and some Science Sats...No more nifty Weather pictures of hurricanes from space on the 6PM weather forecast.
Assuming you are serious, it is an orally usable form of tobbacco. It comes in forms from a fine powder (like talc) to a kind of coarse ground about like coffee. Often it is flavored with menthol, etc.
It is popular with snokers who work in areas they cannot smoke, this way they can get thier nicotine "fix" without lighting up. The stuff is nasty and often new users swallow some, thus causing them to disgorge thier stomach contents. The saying "up to snuff" means having a strong constitution so that one could hold thier lunch down after ingesting some snuff. It may also mean the ability to tolerate snuff, which I am told tastes horrible.
NATing is only part of the issue, not the whole thing, you still have the TCP/IP traffic to deal with so that packets get TO the game.
If you RTFA this "game router" is really only adding traffic shaping/prioritization, which is something a middle of the road router can do anyway in FIRMWARE which will be lots faster than that software. Also you have to use good NICs (more $$$) on the old PC, which if it is an ISA bus PC good luck finding them, and if you find then you still got a 66MHz backplane in that old Pentium.
There are lots of complexities here, it's not something your average gamer is going to build. Maybe a network guy who is also a gamer would do it, but it's not an entry level project. Like someone else said, spend the money and get something built for the purpose you will be happier.
No, pushy usually pisses them off. You just say when I leave I'll just have to tell them (take person's name)wouldn't let me in and was an asshole as well. WIth the emphasis on "being nice" these days I bet they let you pass. Another trick is to be a very pretty/sexy female (big tits, low cut dress, short skirt, etc.), or to use one to decoy the guard while someone else slips by. Of course if the guard is female you are sunk unless you happen to be Joe Handsome:)
Are you sure about the degrading part? What if some females actually LIKE what they are doing? Are they degrading themselves and are we supposed to "help" them out of it?
If you look at the facts, women porn stars are multi-millionaries and the guys (with few exceptions) are just used and tossed out. So WHOM is getting degraded? And I don't see lots of women spending the $$$ to sign up/buy porn, it is 90% men.
Anything that should be censored is porn you say, well how about extreme violence, say someone getting beheaded or such...don't you think that should be censored too? Or does it have to involve nudity or partial nudity (no tits, or tits are OK just nothing lower?). It is a VERY slippery slope and that is why the Supreme Court has ruled it is a LOCAL issue to decide. This is just another attempt similar to that one pushed by Sen. Hatch which the SC struck down as unconstitutional. This one if it passes will be too.
Excellent analysis! I still wonder though if all the information we DO have represented in the form of ones and zeros(anyone have any clue as to that?) what the energy that was used would be?
Not all utlity poles are public property. Many times the company pays for a thing called an "easement" and they either buy or lease the land from the owner (for a pittance). In the city, I suspect most of the poles/towers are on city right-of-way but not all are. I'm wondering when they will just start taking the land they need for towers under the new "emminent domain" rules upheld by the Supreme Court:(
Not to doubt your math but all the computer and other devices running in the world today must consume a HELL of a lot of energy. Plus all the bits of information that are stored now used energy. Just look at the billions of computers in use today doing things from running the washing machine to the Space Shuttle and flipping those bits all the time, billions of trillions of operations a second using kT energy. While the math and physics seem right, this one does not pass the common sense test. I also assume you are using a brute force attach which no one in their right mind would try unless as a last resort. A 219 bit counter can only count to 2**219 -1 which isn't that big of a number, I'm pretty sure we know prime numbers bigger than that. The Errata section makes more sense.
It depends, using Grid computing to run a cracking algorithm and/or some things you may know about the person to get some ideas about the passphrase it could take less than millions of years. Then again, you could always use tortue or maybe blackmail;)
Journalism is reporting INFORMATION most often to the masses. The masses are NOT going to go look up ThinkSecret. Thus repeating the info from the web, while it is a bit lazy, isn't nearly the evil thing you make it out to be.
I guess I'm an evil immoral monster then. I'd rather 25000 Iraqis dead for THIER country IN their country and while I regret the deaths of ANY Soldiers, the miltary deaths have not yet equaled the losses at the WTC and Pentagon and those folks were NON-COMBATANTS. Anyone who thinks otherwise is a immoral evil monster who does not deserve the rights the men/woman have been dying to protect for 200+ years.
I suggest you go read the Koran where it tells them to KILL the infidels where ever they may be and then tell me the war against Terror is unjustified. They are not going to give in until the last "infidel" is dead, so if you value your way of life, get on board or get the F*CK out of they way of those trying to protect themselves or mark my words, we WILL run over you.
I'm done battling some one who is an idiot, I got much better things to do than deal with kids.
You can always encrypt the sensitive files on the encrypted hard drive. Use a very long passphrase and you got pretty good security, but with time it is crackable.
I've seen it both ways, where the whole drive is decrypted with the key or where each application has to decrypt. Both have strong and weak points. It all depends on what you consider secure enough!
No, it shows how litte YOU understand journalism. ThinkSecret has been farily accurate in predicting the moves of Apple. So, it's just the same as if they had reported a political rumor and quoted a "reliable source". The source is a web site but there is a HUMAN who writes the copy on the site. True journalism uses multiple sources for information, and then tries to present a fair report giving all sides. But that concept has not been around for a long time.
Get off the War topic. You are beating a dead horse. And CNN was actually NOT a very pro-war news outlet, all you have to do is see a few of thier commentators and it's pretty clear where they stand. CNN is very, very anti-Bush on any topic you want to bring out.
