  1. Re:Magneto-optical or, cautiously, tape on Ask Slashdot: Best Offline Storage Method For Large Archives? · · Score: 1

    So if you throw enough money and person hours at the problem, you can mainly solve it. Check.

    At work we used to do tape backup with 4 current tapes. Last year, last month, last week, and yesterday. Every week was stored until the end of month. Every month was stored off-site until the end of year. Every year was stored off-site.

    Well, it worked. We did have a real problem verifying that the backups were good, and occasionally they failed. (At one point the read head engaged the write head, so that after reading the tape, it was blank. Yuck!)

    But that's a solution that's expensive, slow, and requires a lot of personnel involvement. Not at all suitable for an individual. Also, eventually we got to the point were we were still backing up yesterday's data when people started logging in. Uh-oh!

    I don't know what the current solution is. I expect that individual computers are no longer being backed up, but I don't really know.

    A better answer is needed. Better has dimensions of both cheap and easy. Removable hard disks have obvious attractions, but it's still too slow. My current (personal) system has two hard disks that are synced occasionally with rsync. Not perfect, by any means. I also have the really important data occasionally copied to a usb key. (So it's got to be *really* limited in size.) And a larger chunk is occasionally copied to a DVD. Not a good answer, but better than nothing, and not so onerous that I won't do it whenever I start getting nervous. But this is a SMALL dataset.

    P.S.: I consider relying on current cloud offerings to be ridiculous. Companies frequently go out of business without warning, and do you own the data that's on their computer? If the company goes bankrupt, what assurance do you have that it won't either just be discarded, or sold to the highest bidder at the bankruptcy sale? You sure won't be able to sue them! And I'd bet that their EULA permits them to just quit offering the service without any warning and without any reason, so even bankruptcy isn't necessary, just a change of their business plan. When we relied on off-site storage, we owned the tapes. I.e., the physical media. So it would be illegal for a bankruptcy to sell them off. (Doesn't mean it wouldn't happen, as bankruptcy courts seem to frequently ignore the law, but it's much less likely than if they owned the tapes.)

    I think it's been decided that Nemesis "probably doesn't exist". At least in the form originally hypothesized. But there are tentative signs that *something* exists that does approximately what it was proposed that Nemesis would do. Tentative is far from proof, however, and "something" could cover everything from a black hole to a large planet in an eccentric orbit. Depending on how much of the evidence you wish to attribute to chance. (Some of it clearly is, but how much? And we can't tell. Besides, given the proposed mode of action, lots of times one would expect the asteroids to just go into very eccentric orbits...perhaps hitting us later, but usually either having orbital decay and regularization, or being captured by Jupiter or Saturn.)

  4. Re:Does it matter to dark matter? on Do 'Ultracool' Brown Dwarfs Surround Us? · · Score: 1

    No. Brown dwarf stars are made of baryonic matter, just like you and I. Dark matter must be non-baryonic, or physics needs to be totally redone. (A difficult job, as coming up with even one chunk of math that matched what we know of quantum behavior took lots of work.)

    Basically, current physics predicts the number of protons+neutrons created at the time of the "big bang", and thus the number of baryons in the universe. There aren't enough of them to account for the "dark matter". And all current alternative theories seem to agree on the number of baryons (at least approximately). E.g., the crash of branes is one alternative to the big bang. Some of them could probably be adapted to allow differing numbers of baryons (I suppose that if the universe is cyclic, perhaps not quite everything collapsed at the last big crunch), but the ration of hydrogen to helium needs SOME explanation. And the one that currently seems to fit predicts a particular number of protons+neutrons in the universe. So dark matter isn't composed of protons or neutrons.

    You're missing the point of the "Nome to Mexico City".
    1) I'm assuming overnight stops, lunch breaks, etc. That was the reason for "45 minutes if very infrequent". I could easily stretch it out to an hour, but every extra minute makes the option less desirable. (As I said, the concept doesn't have sharp edges.) The purpose of the "Nome to Mexico City" was to ensure that there was a requirement for refueling during the trip. (If it could handle that without problems, then it could handle any expectable trip.)
    N.B.: I'm assuming that you overnight at motels with charging capability. So I'm assuming that that's not a problem. But you still need to be able to put in a day driving with a bit of reserve in case your motel is full and lost your reservation.

    2) The other consideration is: most people don't keep a separate car around for when they go on vacation. So the "general purpose vehicle" has to be able to handle the "going away for a week" trip. A battery exchange program would solve this.

    If I understand correctly, the application of this technology to aluminum *is* new, and I suspect that there will be a number of (legitimate) patents surrounding it. It's not just deciding to replace one metal by another, different metals behave quite differently.

    OTOH, it may be something that will break "the magic 300 mile range". But I doubt that it will allow for quick refueling short of a battery exchange. I don't think that even super-capacitors could do that, as the power requirements for a fast charge are a bit appalling.

    That said, I'm certain that it will have MANY uses. Some in power transmission, some in other areas. (Earlier comments have lead me to believe that this company won't be interested in pursuing powering consumer gadgets, but in that case they'll probably be open to licensing for that purpose. Which could be very useful.

    But I don't think that electric cars will ever be practical as a general purpose vehicle without implementing a battery exchange program, or something equivalent. (Some types of battery operate on a flow-thru principle, so in principle you could treat that just like a two-part fuel, with regeneration done at fixed stations.) FWIW, a general purpose vehicle must be capable of driving from Nome, Alaska to Mexico City (given suitable roads) in one trip without extensive layovers. I do admit to the necessity for stops along the way to refuel, but they can't require more than 45 minutes if they are very infrequent, or 5 minutes if they are frequent. (Yeah, that's quite vague. Intentionally. I don't consider "general purpose vehicle" to be a category with hard edges, but rather with very fuzzy ones. And I acknowledge that some people would reasonably include off-the-road requirements, but I don't. And I'm willing to consider a shorter maximum trip length...but 300 miles isn't long enough. San Francisco to Los Angelas is a bare minimum.)

    So I end up thinking quite highly of battery exchange programs for electrical vehicles. Which means standardization requirements for battery shape and connectors. But it's best to wait for the proper battery technology...or to have a standard that is flexible enough to allow variation as technology improves. Which is tricky in and of itself. (Note that under a battery exchange program, you wouldn't own the battery in your vehicle, just the power that it contains. So this would mean that there were various social adaptations necessary, e.g., Mobile would need to be willing to accept batteries owned by Shell in an exchange. Do they charge them? Relabel them? Ship them off to Shell? Can they charge a premium for accepting someone else's battery?)

    If footprint were completely irrelevant, then it would be a solved problem. It's only of lesser importance, which means that really huge batteries with low efficiency aren't feasible.

    N.B.: if footprint were irrelevant, then one solution would be to build a large tank covered by a heavy weight. To store power, you pump in some fluid underneath it. Air would work. To extract power you run it through a turbine. You need a fairly heavy weight, so use the house. (This, additionally, gives you earthquake protection if you use proper design.) That means you can store the fluid under lots of pressure, so you can run the turbine at high efficiency. Simple, reliable, efficient...but HUGE. And simply because it's huge it's expensive in many different ways. But with a heavy enough weight, and a large enough tank, you can store as much power as you want. And if the fluid has low surface tension (which makes sealing the tank difficult) you can have excellent efficiency. (This is actually a reasonably good mechanical analog of a battery.)

  8. Re:It has to get worse before it gets better on UK Developers Quit US App Store Over Patent Fears · · Score: 1

    Sorry, but pre-US the "patent" was an exclusive right to do or make something granted by the government. Sometimes it was a patent of nobility, sometimes it was a patent on jam making for use by the King. Sometimes it was a patent on a kind of dyeing. The central idea was monopoly.

    What the US did was extend that idea to all inventions registered with the government. And the implementation shows that the implementors (if not the originators of the idea) desired it to be another way of concentrating power. As it had been in Britain. They did, however, face political opposition which held that patents should be as you describe, so they had to make compromises that leaned in a more open direction. So, basically, anyone could potentially get a patent. But using it practically was something that only the quite rich could succeed at. And since they were practically useless without a sizable fortune, the wealthy could buy up patents cheaply...or, generally, violate them with impunity. (Though the "violate with impunity" was also something that the poor could do. Just not anyone worth suing.) Very occasionally someone who started out moderately wealthy was able to use a particularly significant patent to climb into the "very wealthy", but generally they were only useful for maintaining the very wealthy as very wealthy, and for fighting amongst themselves. And as time has gone on the "concentration of power" aspect of patents has increased, while it's utility to anyone besides either the very wealthy or the patent troll has diminished. By now that nearly all that's left.

    I could see the value of a system analogous to patents in making or using inventions with a tremendous up-front cost. But not of the current patent system. And not of anything I could envision it being "reform"ed into.

    I can accept the possibility that there could be a reasonable patent system. We don't have one. The legal aspects that you point out do make things considerably worse, but the patent system itself is horribly broken...broken to the point that I doubt that any repair is possible. It was broken at least as early as the invention of the telephone, when three separate and independent inventors appeared and *one* was granted a patent. Evidence appears to indicate that it was broken considerably before that, but I don't know anything really convincing. A case can be made that Eli Whitney did deserve a patent on the cotton gin, but do notice that he had to spend most of his time afterwards defending against infringements. So even though he deserved the credit for the sole invention, he didn't deserve what resulted from it. I'd call that broken, even if it's broken in a significantly different way. (Then there's the question of "Was it really a social good?" considering that it made slavery profitable.)

    I think you're believing the propaganda. Patents are, and always have been, about concentrating power into fewer hands. That's one reason that they are expensive to get, use, and defend against. Copyrights did not originally have that purpose, though they have come to. Copyrights should not be allowed on any material "protected" by a DRM system unless that material is filed in a library of deposit WITHOUT the DRM. In a form suitable for reproduction and use. (Yeah, I'd count source code with the toolchain required to build it as satisfying this requirement. Even a binary would do, though in that case only the binary would be protected by copyright.)

    The importance of the library of deposit is that the material under copyright should be guaranteed to eventually be released into public domain, or the copyright should be invalid. That's rather clear in the constitutional provision made to justify copyrights.

    As for "get worse before it gets better", it will only get better if a viable better choice appears. For software I've found GPL software to be a viable choice. Others haven't. Their tough luck. If they ask my advice, I'll advise them. I'll often even assist them...but not in making stuff work that requires that I agree to onerous terms. So "I don't do Windows.", or, anymore, Mac. (Apple crossed the line 5 years or so ago, when they slipped a line into the terms of one of their software update packages that said "You agree that we have the right to add, remove, delete, or copy any file on this computer." That could mean something innocuous, but it could also mean something I don't choose to deal with. And I know which meaning an opposing lawyer would choose.)
