Raid 5 runs just fine in degraded mode until your extra drive gets there. I have one right now using software raid 5 in linux with a dead member waiting to be replaced. 0 downtime or data unavailability so far.
I didn't read the article, but I think the general idea is to inflate it with something other than air. For example, inflate it with water and let it freeze solid, and the walls double as radiation shielding. That leaves the problem of launch costs for all that water, but it does make construction simple.
Akamai didn't mess up the net. Akamai messed up some web sites that are akamai customers. Remember kids, www is only a subset of the internet, and akamai customers a small fraction of the www.
Who said scientists and governments aren't dealing with it also? In typical slashdot fashion, this article will be taken way out of context by everyone. It's just a report written by one insurance company, intended only for other insurance companies.
Unlike cloning dinosaurs and time travel, this isn't sci-fi BS that they are talking about. They aren't looking into grey goo or other technophobic crap like that, the article is simply about the effects of nanoscopic particles on living tissue. There is evidence to show that nanodust could cause lung problems or worse, and research needs to be done before nanotech starts being widely used.
Uhm, they aren't talking about skynet or grey goo or any technophobic BS like that. They're talking about nano-sized dust that could cause problems similar to asbestos when inhaled. It's absolutely a real problem that should be researched.
It's not symetrical by the definition of symmetry of course, but the universe is the same density as far as we can see in any direction. There's no one direction that looks like a better candidate for a center than any other.
Think of it this way... You put 2 magnets on a rubber sheet, stuck together, then you stretch the sheet. The sheet will expand underneath them, putting some force on them, but the magnetic force between them is much stronger and will keep them together.
Now on the scale of molecules, planets, solar systems, even galaxies, expansion is tiny still. The intermolecular forces, electric, magnetic, gravity, whatever will all overpower the expansion by many many orders of magnitude. IIRC the estimates for expansion are something like 20km/s per 1M light years. That works out to 0.00000000000000000211 meters/s per meter of space if I did the math right.
So basically, space is expanding everywhere, even inside you, but it's so slow that your molecules just hold together while expanding space slides out from under them. It's only in the huge empty space between galaxies that it's easily measurable.
50-100 years is nothing, and it's not the fuel or exhaust that you need to worry about, only the parts of the reactor itself that become radioactive from neutron bombardment. So, we only need to store retired reactor parts for 50-100 years, which is much less mass and much less duration than what we currently produce from nuclear plants, and massivly less environmental impact when compared to the equivilent fossil fuel usage.
no, no, and no. It's going to be a million miles away and it's only 2 miles wide, it's gravity would be damn near nothing even at it's surface, let alone a million miles away.
Yes, but even if they fire multiple photons, you can't pick out individual photons from the stream without disturbing others, and you especially can't pick out only the ones that are duplicates, which would be necessary to pull off a man in the middle attack undetected.
I dunno about your car, but in every one I've driven the cruise control button only enabled CC, it didn't engage it. So, you could leave it on all the time without ever using cruise control.
Now, assuming you don't need cruise control when you're in 'race mode', the button makes a good mode selector for race/normal. With it off, you're in race mode with no CC, with it on, you're in normal mode with CC enabled, and you can engage that as usual with the rest of the CC controls.
No, orbits are horizontal. When you watch a rocket launch vertically, it's only the first couple miles up that are vertical, after that they start to curve towards the orbit they are aiming for, and they start accelerating horizontally and decelerating vertically.
Wether or not google can find a way around it, or even if the guy didn't write the software he claims to, is meaningless. The (alleged) fact that he threatened to harm the company if they didn't pay him is extortion, and he should go to prison for it if it's true. It's that simple.
I love slashdot, you can talk out of your ass and make no sense at all, and get +5 insightful. A turbo engine has a turbocharger, which is a device that uses exhaust gas to spin a turbine, which then spins a pump to presurize the air coming into the engine, increasing the amount of oxygen so that more fuel can be burned.
Except when you only have 1 place to get your car serviced, you can't get a second opinion, and you have to take their word for it that the expensive repair they propose is necessary.

Yeah alot of people say independant now, but originally it was inexpensive.
Well that's a problem with any raid level. Although with raid 10, you do have a chance of surviving a second failure.
That's the whole point of raid (at least it used to be). You make up for the unreliability of the cheap drives by making them redundant.
RAID is an acronym for Redundant Array of Inexpensive Disks.

Because it's a prototype, and they need a way in when they're debugging the wireless hardware/software.

Don't forget this one.
No. There is absolutely NO evidence for that, and it's not even physically possible for it to have happened.
badastronomy.com has an execelent debunking of that rediculous claim and many others.

It's a battery, it stores the energy chemically. Capacitors store it as an electric charge.

They're testing it over the pacific ocean.

My vote goes to the IRS. The cost of that hardware could easily be recovered by better auditing systems catching tax cheaters.
