Is Germany Raising a Generation of Illiterates?

Just wait until the pupils affected by the change are old enough to actually take the PISA test.

Private Keys Stolen Within Hours From Heartbleed OpenSSL Site

michelcolman Re:I can't use cloudflare, connection is insecure (151 comments)

In Safari on my Mac, I got a warning saying the security certificate could not be verified, and I could choose to simply continue. So then I got the text saying I shouldn't be able to see that site. Shouldn't the browser have actually said the security certificate had been revoked?

How Many People Does It Take To Colonize Another Star System?

michelcolman Re:People need to start with the scale (392 comments)

The fastest spacecraft we built never got anywhere close to light speed. If we can somehow figure out how to get to those speeds, the univers will shrink through Lorentz contraction and, in theory, it's perfectly possible to get to another galaxy in a few hundred years. Years measured on board, that is. Of course for earth many thousands (or millions) of years will have passed.

P vs. NP Problem Linked To the Quantum Nature of the Universe

michelcolman Re:Computable? Simulatable? (199 comments)

They'll just restart it from a recent backup and we'll never even know it happened. If you were to start your life again yesterday, without remembering anything from yesterday or today, the whole world including your mind restored exactly to the state it was in yesterday, then time would appear uninterrupted. So if you keep trying to generate bus errors which keep getting fixed with a reboot/restore, it will appear that none of the experiments worked and you might conclude that the universe is not a simulation. In fact, there's no way these bus error experiments would ever result in anyone concluding it is a simulation.

China Cracks Down On Bitcoin, Cuts Off Exchanges' Bank Access

michelcolman Re:As they should... (100 comments)

Yes, you might make a list of all bills, where they were last spent, and try to make a pattern out of that to find the bad guy. Indeed, this technique often succeeds. But compare that to "bills" that have a record on them of every transaction ever made with them. Wouldn't you agree that that is more traceable? I never said cash is completely untraceable, I'm just saying it's wrong to say that bitcoin is untraceable when in fact it is much easier to trace than cash. I'm sure the NSA absolutely loves bitcoin.

China Cracks Down On Bitcoin, Cuts Off Exchanges' Bank Access

michelcolman Re:The Sky is falling! (100 comments)

Look at the longer term chart, and look at how similar the current drop is to the drop that occurred about a year ago. Make sure you take a logarithmic chart to see the similarity. It went from $250 down to less than $50, up and down again a few times, then up to $1000 several months later. If you bought at the peak exactly one year ago, you would still have a very nice profit today.

So what if it went from $1000 back to $400? Given the history of the prices, that's peanuts. Last year was much worse.

China Cracks Down On Bitcoin, Cuts Off Exchanges' Bank Access

michelcolman Re:As they should... (100 comments)

I would venture that the bitcoins will be easier to trace and find than the dollars/yens/whatevers. They may be in some unidentifiable wallet, but as soon as someone uses them to buy something, those bitcoins can be traced back to the illegal transactions. They may have used all kinds of trickery to disguise the transfers, but that's actually harder to do with bitcoins than with cash.

China Cracks Down On Bitcoin, Cuts Off Exchanges' Bank Access

michelcolman Re:As they should... (100 comments)

Bitcoin is more traceable than cash. The bitcoin chain contains a record of every bitcoin transaction ever made, anywhere. There are some randomizing anonymizer services which take money from lots of people and return it randomly so nobody knows exactly which amount came from which source, but that kind of services exists for other currencies as well.

60 Minutes Dubbed Engines Noise Over Tesla Model S

michelcolman Re:Lies (544 comments)

They definitely need a kind of "soft horn" to warn people in a polite way. People may just stand in your way in a parking lot without knowing you're ready to drive off. Something like Knight Rider's "wuw-wuw" sound would be nice...

But please don't make them make sound all the time, now that we can finally have quiet cars!

60 Minutes Dubbed Engines Noise Over Tesla Model S

michelcolman Re:Lies (544 comments)

Adding noise from some random car to footage of ANY car is just unacceptable. People like to know how a car sounds. If you show a Ferrari with the sound of a Beetle, people will complain. How can anyone find this a normal thing to do?

Why not just substitute images of other cars as well? Make an article about a Tesla but actually show video footage of a Mercedes, why not? (In fact this is done all the time with airplanes).

How interested are you in Virtual Reality tech?

michelcolman Re:VR again? (202 comments)

I wonder if people who play with these things a lot, are going to turn their head more in real life as well. If you've been forced for several hours to turn your head instead of moving your eyes, you may keep that habit when going out for a walk afterwards.

Apple to use LiquidMetal for fuel cell

michelcolman michelcolman writes  |  more than 3 years ago

michelcolman (1208008) writes "Apple has been granted its first patent related to Liquidmetal, a space-age metal alloy. But the patent isn’t for a new iPad enclosure or iPhone antenna, as experts have predicted. Instead Apple’s Liquidmetal patent is for an internal component of a fuel cell. Apple’s new patent describes “amorphous alloy” collector plates for fuel cells, an electrochemical battery that uses hydrogen to generate electricity. Although the patent doesn’t reference the Liquidmetal trademark, the material is an amorphous alloy or “ metallic glass”. Last year, Apple signed an exclusive agreement to use the Liquidmetal Technologies’ IP in consumer electronic products. But of course, the ever-secretive company hasn’t hinted at its plans for the material."
