Multiple-Tesla fields that are changing their orientation rapidly in time aren't particularly healthy to be around. Induced currents in your nerves, heating, etc. That MRI field is acceptable because it's DC. That is, if you don't have any ferromagnetic objects on you.
No, the superconductors are not simple magnets.
What's on the tele then?
Rockets being the only solution does not automatically mean rockets are a viable solution. Please quit ignoring the real challenges presented.
Unfortunately, this can't be approached as an engineering problem and get the result you would like. It needs to be approached as a problem in fundamental research of the physics underlying our world.
There were lots of efforts to miniaturize the vacuum tube. They only resulted in smaller tubes. It took new insights in fundamental physics before people could understand how to make a transistor. There were many experiments with germanium (a natural semiconductor) that could have led to the transistor before 1947 if anyone had understood what was happening.
Some steel. Not all of them. That's why the refrigerator magnet doesn't stick to that silver door.
A field strong enough to work on water would kill you first.
Look at the amount of money made on oscillococcinum, and you might agree it's a successful hack to make money from the stupidity of others.
This would be cool if it was more than a stage trick. The superconductor needed to do this used to be mail-ordered from Edmund Scientific. So lots of hackers were doing levitation demonstrations in the 90's. People think it's cool because they've not lived through that, or have forgotten it.
It works on the principle of superconductors excluding a magnetic field. When they are cooled to liquid nitrogen temperatures. Steel is low in ferromagnetism and isn't as good a conductor as copper so it's not as good for making electromagnets.
Well, I did that once with a bottle of liquid nitrogen from Airco and a superconductor I bought from Edmund Scientific. This was before there was a Slashdot. So, no, not impressive.
Before someone makes a working hoverboard, we will first hear about the principle that makes it possible. Because one that's practical is almost guaranteed to get someone a Nobel Prize. And certainly Lexus would go for that if they could.
No new principles lately. There is an existing principle of magnetic repulsion that would work only in an extreme condition. One requiring really special stuff buried in the street, and probably including liquid nitrogen to keep it working for even a short time and a few feet.
So, it's a gimmick.
Hey, I hang out with a lot of creative people. Not Elon Musk, but Steve Jobs for more than a decade, and lots of people at least as smart that you don't know. They can be really brilliant, and successful, and they can still make really stupid mistakes and sell them to the rest of us pretty well because they believe in themselves completely and they have a track record. I've done that too.
That's the hyperloop. Something Elon never meant to stand behind (and still really isn't), just put out there to torpedo a worthy project that he didn't believe in.
Anyone who looks at the hyperloop design can see it's not a no-brainer. It has safety issues up the wazoo
Meanwhile, little Switzerland can have incredible trains everywhere and the United States can't get it together, and unlike with rockets and cars Elon's not helping this time. And I am not sure that the "lease" part of his solar business is a great thing for the world either.
Although the hyperloop is possible and might even be practical someday, let's please be honest about the reason it was created. Elon Musk just wanted to kill the California high-speed rail.
That might have been OK if there was a hope that we could actually replace it practically with a hyperloop. But given the history of bleeding-edge rail - ride any maglevs lately? We haven't even had much success with monorails outside of theme parks and Las Vegas - we don't really have any working system to replace high-speed rail. Hyperloop should really be called "Pipes that carry People" and we need decades of work on it before considering intercity lines.
Honestly, as a last resort, it's not a bad idea. I have a fair amount of ESD test gear at work, including a bunch of static discharge guns and the like that can be dialed up to some crazy levels. I was once stuck in a situation much as you - they controlled the modem/router and it was crapping out every few hours, and they were the only game in town for non-dialup access (this was 15ish years ago). I'd already replaced it with a spare that did not have the issue, but since it wasn't provisioned, the only place I could go was their internal pages.
I spent probably two hours going through L1 support, L2 support, and then had them tell me that "oh, sometimes the boxes just do that". So I took the box to work, fried the shit out of it, plugged it back in to let it power up and do real damage to itself now that half the fet gates were probably cooked, and then called them back to tell them that the box had finally crapped out and started smoking. They promptly sent me a new one, and told me "must have been lightning or some sort of power surge."
Yup, a power surge indeed.
Yes, but calling for segregation is.
If you think that's an honest call for segregation, than I shudder to think what happens when you're at a stand-up comedy show. Then again, Jerry Seinfeld made that point recently.
So is stating that women are not capable of handling criticism (unless you've got some objective evidence).
How about the example where the Nobel prize winning scientist made a poor joke that they can't take criticism, and it blew up into a huge feminist issue with him being labelled a misogynist?
Cygwin is the worst answer to pretty much any issue on Windows ever. Forcing a POSIX environment onto the Windows environment to do basic tasks is why Linux admins are so shit at administering Windows. Just learn the damn system you're using.
If you need to have a script saved, just use PowerShell:
Invoke-WebRequest -Uri 'ftp://ftp.mozilla.org/pub/firefox/releases/38.0.5/win32/en-US/Firefox Setup 38.0.5.exe' -OutFile 'C:\Firefox Setup 38.0.5.exe'
If you really want you can parse the output from http://download.cdn.mozilla.ne..., but that seems like a huge waste of time. Just fetch a reasonably recent version and plan to update twice.
Otherwise, just use ftp.exe.
Obviously.
Like TFA says, you need to look at it like a research OS. One that has critical flaws that are designed in, but that design has a purpose: to function in a different way. Doing so can expose new lines of thinking and novel approaches to "solved" problems. No, it won't function in a real world of networked computing, but it's not supposed to fit into that idiom. It still has some very interesting ideas. Spending time solving every problem again isn't the goal. There was a time when virtual memory didn't exist, for example, and computing still worked well enough to run businesses, banks, telephone networks, and governments. We don't need a research OS to show us that virtual address spaces are useful. We know that already. So, ignore it as not relevant, and do something that is a novel approach.
Looking at the ideas in TempleOS like they will replace Linux or Windows is silly, but they might give us ideas for new types of computing. The idea that everything would be better as a Linux device is, quite honestly, poisonous to the development real progress in the field of computing as a whole.
Maybe TempleOS is like non-Euclidean geometry. Sometimes need drives the development of new math -- Newton's development of Calculus -- and sometimes the math is developed and sits idle, doing nothing for nearly a hundred years before changing the world -- like Boolean algebra. A computer system is just a very complicated set of mathematical rules. Changing the rules of math and seeing what happens has been one of the major forces of change, as different systems are often best expressed in different forms of mathematics.
Does TempleOS make it easier to understand how computers operate? Does it make it easier to learn what a program actually is? Is it just an example of being closer to the bare metal, like you were flipping bit switches on an old Altair 8800? What if, for example, a system like this makes it very easy to model artificial intelligence? It can basically reprogram itself, after all, as everything is JIT and source code is readily available for literally everything at all times. That seems incredibly powerful. Is it possible to write a self-refining program in HolyC?
Just because I don't understand what something could be used to do doesn't mean it's useless. It might just mean I don't have a very good understanding yet. The questions to ask are, "What kind of system benefits from the design of TempleOS? What kind of system benefits from raw, unimpeded access from the user or input to the hardware?"
