Um, thought that was already the case, and the cause for a bunch of legal dispute when the recording industry wanted to limit/end sale of CD-r's claiming they were only used to break copyright law(cant make money off the sale of something then turn around and claim its illeagle to sell said thing).
Nope, they have TITS (Taking IT to the Street), at least thats the title of the article. Who knew that all it would take were some TITS to reduce crime! So Im guessing the database is really a 200Gb Pr0n stash..

Those ICE CAPS were thought to be CO2 Ice, not water ice. There is a big difference, mainly that CO2 is not H2O.
And yes, they do actually work quite well. My cousin had one (got it for free somewhere) and we were taking turns knocking ornaments off the christmass tree with it this past december, from a different room.
Though the point is that you currently have to carry the hydrogen anyway, with the scramjet you dont have to carry the oxygen component (the main component by mass).
Re-entry would be a gradually increasing load as the vehicle starts to descend into the atmosphere. A rail-gun style launch would be an almost instantaneous acceleration of several G's lasting for the length of the rail, then deceleration from drag (unless you are under power as well). Two almost totaly different load patterns.
Only then would you need to worry about gold melting on it. Silver actually melts at a lower temp., but still hotter than you would want your cpu to ever reach, 1763.2 F.
Silver, being a metal, is very conductive. Conductivity in the electrical realm generally translates into better conductivity in the thermal range as well. So yes, a 99% silver compound would transmit heat from cpu to heatsink better than your standard paste. A 99% copper paste would be almost as effective, but its affenity for oxygen would cause it to break down into a green sludge of oxidized metal rather quickly.
As far as the danger of putting a potentially conductive paste on top of your CPU, yes it can be dangerous, if you dont know what you are doing. The ceramic core of the cpu is the ONLY part that needs any paste. Covering the whole chip can short-circuit the bridges and other circuitry on that surface, and even though there is a protective layer of laquor, there is still a risk. Adding too much can allow it to ooze out onto the motherboard and short something else, possibly the CPU pins. Too much compound will also actually insulate the chip rather than cool it, as it adds more material that the heat has to conduct through. During my stint as a repair tech, I had a few fried CPU's from people not reading directions/having a clue, and covering the entire surface of the CPU with the stuff. All the paste is supposed to do is eliminate any air gap between CPU and heatsink. Newer CPU's mihgt come with a metal shim on top of the chip (Ala the old K6-2's), giving a wider dispersion path for the heat to travel before jumping to the heatsink through the paste.
If you buy almost ANYTHING with a warantee, it only warantees itself, not what it might do to other things even if used properly. Is your car waranteed against getting into an accident? No. The lack of silver will reduce its conductivity, but the rest of the components in the compound still conduct failry well. The worst that would happen is a cpu might run warmer than it would with the silver. If your system is so critical that lack of silver burns up the CPU, you probably voided a different warantee already (Overclock something??).

ps: I bet they are gona take the cost of this recall out of their supplier, seeing as the supplier sold them something claiming to have x% silver, but breached contract giving them 0%. Must have saved the supplier a load of $$ to not put that silver in, but guess they will pay for it now.
Maybe its old news, maybe someone else already commented on it, but IBM aired a TV Comercial featuring Linux as a 9 year old kid. Just kind of took me by supprise seeing an ad on TV for Linux.
So, it would let air in before you got it sealed. Even if you managed to use a closed-cell aero-gel, most are not structuraly strong enough to hold the two panes apart under vaccume. Even if this were possible, being able to open/close the window would shear the foam/glass junction, and installation would be problamatic as there would have to be aerogel between both halves of the frame as well for it to be effective at all. Aerogel is a great material for some things, but its not nearly as strong as steel. If it were, think of what it could do to the airline and space industries. Solid stuctures built of aerogel weighing 1/2000th (aerogel=3Kg/m^3, steel=7850Kg/M^3) what they do now.
That article reads more like an infomertial for foam-based insulation... oh wait, the company posting that article SELLS FOAM INSULATION! Of course they are going to push it, they use it to insulate and re-inforce their Domes. The numbers they report are even not correct, see Here for a table of R values. Its as if they want to create a feeling of distrust for the R Value/certifying agency. They complain about R value not taking into account moisture and wind resistance. R value is the insulation capability of the material, wind and moisture resistance are dependant on the use of the material and how its installed, where, etc. It is the easiest way to determine the insulation quality of the material, as that is what it directly measures. See Here for how it is determined. It is a factor of the K value, something measured directly by an ASTM lab test.
From the article:The R-value is a fictitious number supposed to indicate a material's ability to resist heat loss. It is derived by taking the "k" value of a product and dividing it into the number one. The "k" value is the actual measurement of heat transferred through a specific material.
Would that not mean that R is just the inverse of K? How is that "ficticious", its the same number expressed in inverse units?
I live in a house that is definately not air-tight (none are, but mine is exceptionally not). Its an old (early 1900's, maybe older) mill house built with no insulation, slat-board walls and ceilings (dry-wall drop ceiling added in renovation), and hardwood flooring not sealed to the walls (could even see daylight leak through in one room). Sealing the wall/floor junction with "Great Stuff" foam in a can, and the windows with VisQueen plastic for the winter reduced our heating costs 25-50%, but without insulation in the walls it is still costly. The walls are as cold as the outside air. While making a house wind resistant will be more effective than adding insulation, the house should be built wind resistant to begin with. Insulation is not meant to seal a house from the elements, it is meant to buffer the difference in temperature between the outside wall and inside wall.
The force of it falling is dependant on how hard the surface it hits is. As you calculated above, the velocity at impact is 4.43M/s, giving the 1Kg laptop a momentum of 4.43 KgM/s.
F=M*A, where A is the acceleration of the laptop going from 4.43 M/s (V)to 0 M/s (assuming its not bouncing) over the collision time (T) or dv/dt.
dv is constant at -4.43M/s time is unknown, but assumed to be approaching 0 (harder floor=less collision time). This causes A to approach infinity. Since our mass is constant at 1kg (neglecting all the peices flying off), this becomes 1*(infinity) for the force.
Now, the force is obviously not going to be infinite (in this post we WILL follow the laws of thermodynamics!). Assuming the impact takes 1/10 sec (dt=.1), force becomes 44.3N, that would be on a relatively soft floor, and is 10x what you said. Thus the harder the floor, the more damage it takes, as the impact time drops towards 0.
But none of it really matters. What does matter is how the laptop is constructed. It should be constructed to support its own weight, and be able to take minor bumps/drops/etc. Larger laptops have the luxury of more space for cushion and support, basically allowing the laptop to absorb the impact without snapping by spreading the impact time out a bit (dt gets bigger). They pay for that in weight. Smaller laptops have to rely on stong materials without much give. The smaller clearances and parts means stuff cant move around inside without bumping into something else, breaking, or shorting out, and theres not much room for support/cushioning (decreases dt).
Though this trick will work for ANY html tag that accesses the external server. It doesnt have to be an image. It could be a style sheet, a simple link for the moron to click, or any element that requirs access to the server to get content. As soon as it access the server to load said content, that IP is logged. The only way to avoid it is simply to use an email browser that ONLY displays the email contents (raw), and wont load external content (without asking first). Just another reason I still use pine.
gives them something to complain about I guess: "Hahaha, you got fragged again, you suck" "its not me! its win2000, it sux0rz, it caused me to die!".
Thing is, winXP is a continuation of the win2000/winNT kernel. Sure, a few things got changed in it, but most of the low-level stuff probably stayed the same. The drivers are almost binary compatable (try it, most 2000 drivers work natively in xp, alot of xp drivers work in 2000). Aside from some tweaks MS probably added just so they could say "improves gaming!", its basically win2000 with a bloated gui that makes you feel warm an fuzzy inside, while keeping anything potentionally dangerous hidden, like trying to change configuration settings. Since 2000 was pushed as a more corporate/server oriented OS, and since 98SE was out around the same time, it let gamers use 98SE and blame the other OS since MS didnt say much of anything about 2000's ability in gaming.

Ive run several nat/firewall boxen from old 386s using Coyote Linux. The machines had a whopping 8MB ram, a floppy drive, and 2 10bT NE2000's. If you ask around, Im sure someone would be glad to get rid of such a system for $0, if they haven't already tossed it out already.
True, which Oxygen and Hydrogen are until they are compressed or cooled to its liquid state... PV=NRt holds until then. After that its the fluid properties of the two that take effect. As the fuel is transferred, the empty area in the tanks is no doubt filled with gaseous forms of the two, and as this expansion takes place, the temperature will drop (ever notice Ice form on LP tanks or those Air Duster type cans if you use them fast?). Got my explantion ahead of itself and stuck that in the wrong spot (should be around where I mention fuel expanding in the tank).
Read my other post (a reply to the parent of this one...). The insulation inside the external tank itself is what keeps the LOx and other stuff from heating up. They are also kept at pressure to allow them to get warmer without boiling. The foam that caused the accident was at the point where the shuttle joins the external tank and transfers fuel from it. That insulation is to keep ICE from building up around the junction, as the hoses and such get cold and cause condensation to freeze.
The foam insulation is supposed to keep the tanks from getting too cold (with all that liquid oxygen and hyrdogen).
Too cold? LO2 and LH2 have a defined temperature and pressure at which they stay liquid. The tanks keep it liquid by insulation inside the tank itself, and by keeping the tanks at high pressure (higher pressure==higher temp to boil, same reason water boils at lower temps at high altitude, PV=NRt).
The reason for the foam was to insulate an external portion of the tank, specifically where the tank connects to the shuttle to transfer fuel to it durring flight. Moving this fluid will rapidly move heat from the hoses and anything heat can be conducted through into the liquid (simple fluid dynamics and heat transfer), as temperatures try to equalize. Since the fluid is moving, it is staying at the same cold temp, thus able to suck more heat from its surroundings (in actuality it IS getting colder as the tanks empty, as it is also expanding). Once the outside gets cold enough, humidity in the air condensates, and eventually freezes on those parts. It was this freesing the extra insulation was supposed to prevent (and did), as falling chunks of ice are a bit more serious than foam (think of the difference in weight of the chunk of lightweight mostly air foam, vs the wieght of a similar size block of ice). The heaters will heat these external junctions, hoses and stuctures to prevent ice-buildup (similar to the heaters on airplanes, keeps control surfaces and wings from icing), to prevent chunks of ice from causeing the same thing the foam did, and without risk of more debris falling on the shuttle durring liftoff.
The Proof rating on the bottle, if you have noticed, is 2x the alcohol content in %. This is because 100proof is the content necessary for self-sustained combustion. Try it yourself, 80 proof (as most are) rum/vodka/taquila/whiskey etc will light up as long as a flame is held to it, but wont keep burning on its own once the flame is removed. Try it with anything over 100proof, it will keep a flame going, hence the FLAMABLE warnings on any such bottle.
