  1. Re:And the shift to Databases away from Oracle on Oracle Effectively Doubles Licence Fees To Run Its Stuff in AWS (theregister.co.uk) · · Score: 2

    found the m$ shill.

    Erm...

    I would however never recommend a greenfield install of it at this point. 15 years ago? Easy decision. But now? No way. Old projects will be in MS or Oracle. Everything new *will* be in one of the free ones.

    Aren't shills supposed to try to get you to buy their product? This one seems to be suggesting there's no purpose to it on anything but legacy projects.

    His speculation was that a construct would have a group of particles that move and periodically return to their original state, perhaps moving in a circle, and form a time crystal. In order for this perpetual motion to work, the system must not radiate its rotational energy.

    So, there's still a finite amount of energy stored in this state. It's merely a state that somehow avoids exchange of energy with its environment. No "free energy" to be found here.

    Like that "renewable fuel oil" mess the Navy did a while back that was millions of dollars of waste for a very little bit of fuel

    That was for logistical reasons, rather than environmental. Local sourcing of supplies is always preferred over having to ship it halfway across the world.

    If we're still flying aircraft by then, we're going to be flying them using something with very similar chemical composition to what we use currently. Even if it is just temporary energy storage, it is very convenient energy storage for that task.

    I'm finding it difficult to find meaningful information on this, but it seems the quantum dots are electroluminescent, being lit up directly by the driving circuitry, rather than being excited by an LCD-filtered backlight.

    The Space Station isn't going to be doing anything to space junk, except trying to avoid it. The supply craft is carrying this tether device to test its performance. After it drops off its payload at the Space Station and detaches, before it is de-orbited, it will unspool this tether and see if the electrodynamic drag produced matches predictions.

    I've been saying analog is better than digital for a very long time despite being modded down every time I say it.

    That's because you are objectively wrong. With digital data, loss of data is optional. With analog data, it is guaranteed and unavoidable. As long as your digital systems are held to a higher fidelity than the sensory inputs of the human body, then they are a perfect reproduction of the original data, and definitively better than anything analog.

    You do not gain anything from going from digital to analog back and gain all of the wow, flutter, pop, hiss, etc.

  15. Re: So, how often does it explode? on Scientists Create Battery That Charges In Seconds and Lasts For Days (telegraph.co.uk) · · Score: 1

    The word 'explosion' literally implies something that grows bigger

    The electric arc heats the air around it into a plasma. That plasma expands rapidly, resulting in an explosion.

    It takes a MASSIVE explosion for the shockware to actually injure people.

    Injuries like ruptured eardrums and collapsed lungs...

    But that rapid-expansion bit means explosions have shrapnel, and that is the much bigger risk. Most people who die in explosions are killed by shrapnel. An arc-flash doesn't have shrapnel.

    Well the explosion tends to blow apart whatever equipment just failed, producing shrapnel. Seriously, did you even watch the video?

    From the video...

    It creates a pressure wave, called an arc blast, that can reach thousands of pounds per square inch. Enough to knock someone off a ladder, rupture an ear drum, or collapse a lung.

    That sure sounds like an explosion to me, far more violent than rather slow conflagration you see from the runaway chemical reaction in a li-ion cell. You did see it blow the head off that mannequin, didn't you?

    A capacitor's voltage is directly related to the square root of charge remaining. Start out at 12V, and by the time your voltage dropped to the 3.7V of a standard LiPo battery, you're down below 10% charge remaining.

    Client-side hashing only protects the password if the content server itself has been fully compromised, in which case none of it matters, because the server is compromised and they have full access to everything. They don't need your password any longer. The only value there would be to knowing your password at that point would be if you had reused it on other sites, that they could in turn access.

    All that does is prevent an attacker from intercepting the plaintext password at the server, as it is received and decrypted by the server. The Yahoo breach compromised the hashed passwords, so whether they were hashed by the server or hashed by the client makes no difference.

    Using wiki numbers, a loaded 787 at maximum range will do some 4.2M person-km on 101 tons of fuel. That's ~0.024kg/km of consumed fuel. A Prius with a single occupant will only do ~0.036kg/km. The aircraft is actually a third more efficient than the car. Now, you can carpool, quartering the Prius's number. Meanwhile, aircraft are not always full (increasingly rare these days), shorter flights are less efficient, regional jets are less efficient, the hub-and-spoke means you're not flying directly to your destination. On the other hand, typical car travel is single occupant, dominated by trucks, SUVs, and large cars with less than half the average rated economy of that Prius, and you're not traveling straight line in a car either.

    Where did you come up with three orders of magnitude discrepancy? I could maybe see one vehicle-mile equating to 1500 in a car, which puts passenger-mile production around an order of magnitude higher.
