  1. by DavidHumus ( 725117 ) Alter Relationship on Wednesday March 27, 2019 @10:38AM (#58341522) What is a good use of blockchain outside of Bitcoin? I've heard some plausible ideas - like verifying a chain of custody or the provenance of an artwork - but I don't see how these small-scale, specialized versions can deal with the 51% attack problem. Can anyone come up with more realistic uses of blockchain?

    Indeed, verifying provenance is about the only viable use case. There are additional variants beyond art, such as certifying hygienic treatment of vegetables, and certifying "fair trade" coffee and metals. But tracking provenance won't work as long as you have the possiblity of forged attributions. So you need a list of "accredited attributors" who have reputations to lose if they misbehave. This can also be done in a distributed way, but that adds yet another blockchain onto the base blockchain. And with it more opportunities for implementation defects and operational malfeasance requiring a tower of defenses that all need to be validated and certified a la "who will guard the guardians?"

    A centralized certification authority, or a handful of independent authorities competing for customers in an open marketplace, can implement the usual array of audit measures, developed the hard way over hundreds of years of bitter experience, with far greater efficiency and trustworthiness.

    And once the JWST gets unfolded, if it succeeds at unfolding at all, you won't have to worry about repair/refurbish missions, even if SLS or BFR could take a crew out to its location. Its coolant tanks aren't designed to be refilled, and parts that are bolted into place on the Hubble are glued permanently. It would take a saw or a torch to remove anything you wanted to replace. After a few years of awesome science, it becomes just another metallic asteroid. Could its mirror and sunshade justify a salvage mission? Doesn't seem likely to me.

    Piggybacking on the right of way being assembled for the Houston to Dallas bullet train would be a sneaky way to bypass the many NIMBY, eminent domain, and "not my taxes" issues that any such project will encounter. Staying underground for the entire route would also reduce those issues, but there would still need to be above-ground power, vacuum pumping, and emergency exit sites at regular intervals along it.

  4. Using the atmosphere to obtain enhanced orbital maneuverability is my guess. With the retirement of the SR-71, if some event happens that needs to be observed from an air/space vantage point, you either need to wait for dozens of hours for a drone or piloted reconnaissance aircraft to arrive, or wait for more hours for some satellite's orbit to rotate into sight and try to watch from an angle of several hundred miles away. If a spaceplane could dip into the extreme upper atmosphere it could make a turn to adjust its ground track and get a closeup look within as little as two hours, or less if you have the luxury of coordinated planning..

    The X-37B's test objectives, "advanced guidance, navigation and control; thermal-protection systems; avionics; high-temperature structures and seals; conformal, reusable insulation, lightweight electromechanical flight systems; and autonomous orbital flight" are almost exactly the technologies that you need to accomplish this. The only thing that's missing is in-space refueling.

  6. PayPal has more security than Amazon, that's why on PayPal Has Been Talking With Amazon on Payments, CEO Says (bloomberg.com) · · Score: 1

    PayPal is still suffering from the reputational problems that came with the inevitable mistakes accompanying its pioneering role in the payments space, but it seems to have stabilized as well as any of the other payment processors that you've never heard of used by huge numbers of eCommerce sites. I still wouldn't let them hold my money interest-free, and I don't like anyone storing my credit card numbers (including Amazon). But PayPal has a security feature that nobody other than hardcore financial institutions do, namely the use of out-of-band one-time security codes for payment confirmation.

    Anyone who's been keeping up with security technology knows that passwords are stupid these days - they're easily harvested by fake websites and lost to criminal hackers regularly. Amazon needs to get rid of passwords, even if they impair the frictionless "don't think, buy now!" experience. Interfacing between websites and old-timey phone technology like SMS text messages is practically a black art anymore - most people can't imagine how complicated it is behind the scenes. Using PayPal might well get them there faster and quicker, and with years of experience driving out bugs and attack-proofing, than trying to create their own system from scratch.

  8. Re:Headline Is Missing The Word "Highly" on How Curved Spacetime Can Be Created In a Quantum Optics Lab · · Score: 2

    Fundamental to general relativity is the principle of equivalence, which equates gravity in one reference frame to uniform acceleration in another one. It's why old-school space stations are big wheels -- they create gravity without using mass, by spinning. In the right coordinate system - one that rotates relative to the lab - the ultracentrifuge in a biochemistry lab creates a highly curved spacetime equivalent to 6 times the gravity at the surface of a white dwarf. (2 million g vs 350,000 g).

    Curved optical spacetime analogs are not so special, after all, then. But they don't have the issues with angular momentum, nonuniformity that centrifugal gravity has, so they could make answering certain questions easier.

    Claude Debussy's music is full of these moments, even when you understand its predecessors and influences like Chausson. Most of Hector Berlioz's compositions are tedious at best, but the 2/4 bars in his Roman Carnival Overture take a logical sequence of developing intensity beyond what can be sensibly explained by any textbook in a way that astonishes me every time I hear it.

  15. Re:Nothing to explain on Autonomy Chief Says Whitman Is Watering Down HP Fraud Claims · · Score: 3, Informative
    Well, that too, but it's a lot more complicated. There are several things going on:
    • Meg Whitman is doing something that competent CEO's do routinely, and HP hasn't done in decades, which is cleaning up the books and writing down the value of non-performing assets, like brand names that will never be used again, such as "Compaq", "EDS", "Palm" and now "Autonomy". There's still "3Com" left to go...
    • Whitman is also playing the CEO spin game, which is that when you have bad news about profitability, you pair the announcement with some other announcement to act as distracting red meat to all the short-attention-span tech journalists who can't follow more than one story at a time. If you're Apple, you just need to mumble about some innovative new interaction modality and everyone goes crazy, if your're HP's CEO, you can actually demo a slick new product and everyone ignores you. Unfortunately HP's heritage of selling sushi as "cold, dead fish" has not been purged from their DNA.
    • The actual Autonomy core software is an undeniably superior technology for doing multimedia search and unstructured text search, but it was never actually productized. Apparently every sale was a bespoke one-off, never to be reused or broken apart and recycled the way most complex software is handled. This means that the combinatorial growth of value to expanding customer bases that potentially existed in the software base turned out to be extremely difficult to realize. HP didn't discover this until the deal was closed and HP engineers had spent some time with the code.
    • Nevertheless, during the sales negotiations with HP, the future cash flow of Autonomy was apparently computed as if the future growth of revenue was assured to be as exponential as the combinatorial math of modular software recombination would predict. Autonomy founder Mike Lynch is brilliant enough to make such a prediction in just those terms, and it surely would have gone right over the heads of then-CEO Leo Apotheker and most of the HP board, maybe including Shane Robison, chief strategy officer at the time. Now, is a statement about the finances of a software company based on whether that company's code is an impenetrable rat's nest, or not, a legally actionable, material misrepresentation? Is it something that would be expected to be uncovered by the legions of high-priced accountants deployed by the big name accounting firms during the "due diligence" phase of negotiations? I'm not a forensic accountant or a securities regulator, so I wouldn't venture to guess.
    • There were numerous other red flags http://www.guardian.co.uk/commentisfree/2012/nov/21/hewlett-packard-red-flags-autonomy around Autonomy that led HP's CFO Cathie Lesjak to vote against her boss and all the rest of the board on the purchase, but she was overruled.
    • Finally, HP claims that while there were accounting irregularities having to do with the way future revenue streams for software support were booked all at once, right now. Lynch claims that this is allowed under European rules even if it may be illegal under US GAAP rules. How would that change when Autonomy becomes owned by a US company? Should those high-priced accountants have caught that? Even so, HP claims to have testimony from a former Autonomy executive that those numbers were not merely tweaked, but were completely wack. HP is saying "nyah, nyah, we're not giving out details, and we're not saying who it is" and Lynch must be furious that he doesn't have enough information to try the case in the press and prejudice any legal outcome. HP wants to get Lynch under oath, so a jury can decide who's lying and who's not.

    The wheels of the law grind exceedingly slow, so this will take years to play out. Meanwhile, HP has some decent software to play with, and they are already doing innovative things, like building search into the printers themselves

HP is General Motors, where you could get any color you wanted from 7 or more brands ranging from low-end Chevrolet to high-end Cadillacs, not to mention GMC trucks and tractor-trailers. The press and financial analyst community views HP as a PC and printer company because that's all they ever put their hands on, but HP makes as much or more money off the infrastructure business that makes up enterprise computing, creating more private clouds than anyone else, for example. Enterprise computing is a total blind spot to most PC bloggers.

    There's actually a mobility strategy that can be discerned hidden in all the noise, secrecy and speculation, based on a close reading of published press releases and other announcements and interviews.

    Gram was likely spun off so that it can make deals with third parties for the fundamental smartphone patents that came with Palm, without the direct conflicts of interest of dealing with a HP as both a hardware competitor and a licensor who could turn on its customers at any time. And as a side project, Gram will be the prime sponsor of OpenWebOS and Enyo.

    HP will make a commercial tablet based on Windows 8 that hopefully has all the enterprise security and managability features that have been in Windows forever, and that Apple has never been able to come close to. If Microsoft doesn't shoot itself in the foot, this will take over the void created by the demise of RIM, and squeeze Apple out of the my-company-pays-for-it iPhone and iPad markets. HP and all the Microsoft tablet OEMs are betting that enterprises are already setup with Windows apps that can port to tablets without the massive effort of recoding from C# and VB to Objective-C. They may not be cool, but the get the job done.

    HP will also make a consumer tablet based on Windows 8's consumer editions, and if they're smart, will incorporate a BIOS that will boot Win8 securely but also allow competing OS's such as WebOS and even Android to be installed without the shennanigans that other vendors will make them go thru. HP could even license its own smartphone patents back from Gram (at a very nominal fee) and get back into the phone business, if the Win8 phone turns out to be anything more than the failure that the Win7 phone was.

    But, knowing HP's history, they'll figure out some way to screw it up and lose money at every stage.
