  1. Re:Not read the paywalled paper yet but on Amherst Researchers Create Magnetic Monopoles · · Score: 1

    terms like "synthetic" vs "real" make me cringe. Did they make synthetic tops at Fermilab and higgs at LHC? I'll reserve my excitement for some credible review of this claim and paper.

    It's passed the first stage of peer review; it's published, and is thus probably not complete shit. Next stage is for other people to reproduce the work for themselves, and most of the paper appears to be the sorts of details that you'd need to be able to go off and do that. If you're not a condensed-matter physicist with a suitable lab (nor am I) then you can probably live without reading the full paper. If the result holds up, the interesting parts will be repeated elsewhere. (Which is good. The paper itself is definitely not an easy read, speaking as someone who hasn't properly studied physics for decades.)

    I'm really glad that there's this sort of thing going on, to be honest. It's the sort of physics that fits in a normal lab and a normal budget, and yet which can let us work with all sorts of really exotic stuff. The whole area of metamaterials seems to be really quite exciting overall.

  2. Re:This is cool, but on Amherst Researchers Create Magnetic Monopoles · · Score: 1

    they haven't really found a magnetic monopole. They've created a long skinny solenoid with ends that are far enough apart that they look like independent monopoles.

    My reading of the paper was that that's the physical interpretation of what monopoles are in the first place.

  3. Re:Contradicts current theory? on Amherst Researchers Create Magnetic Monopoles · · Score: 3, Interesting

    Theory (due to Paul Dirac's work combining quantum mechanics and relativity in the first half of the 20th Century) had been predicting monopoles for a long time. Yeah, the simplified version that you were quoting from didn't predict monopoles, but the full version did. If the submitters of the paper have found one of these rare beasts in the lab, that's a very interesting confirmation.

    The real question is whether the result can be reproduced by different experimenters in a different lab. (Since it's lab-scale work, that ought to be possible.) If so, watch out for some really interesting new areas of physics to be opened up.

  5. Re:I like this idea on Kentucky: Programming Language = Foreign Language · · Score: 1

    The Romance linguistic framework is not hard for people who have learned English in a structured school environment, because other Romance language speakers (the French and the Normans) ruled England for hundreds of years in the Middle Ages and set the grammar rules that continue to be used to this day.

    Actually, English is a Germanic language and always has been. It's closer to Dutch and German and Danish (and ...) than any Romance language, and this is particularly noticeable in the basic words and the grammar. However, English has "borrowed" a huge amount vocabulary from Romance languages, particularly French (that's the Norman/middle-ages influence) so its definitely not too hard.

    Of course, a big difference with German (and many other Germanic languages) is that English doesn't really go in for very long compound words: we put spaces in.

  8. Re:X's way is the only feasible way. on Wayland 1.4 Released — Touch, Sub-Surface Protocol, Crop/Scale Support · · Score: 1

    Hence remote X running on any system produced in the past 20 years actually holds the crown as the only system SLOWER than VNC over the network.

    It's only a problem if you're sending bitmaps back and forth across the network, whereas other drawing primitives are fast. The only problem is that too many half-competent developers have decided that the only way to do things was to draw on local bitmaps and then push them to the display (possibly with some extra fetching the display buffer back in the other direction a few times too, just for fun). That's just never going to be all that fast on a realistic network due to the latency involved.

    The proper fix is to strengthen the remote processing model so that there is less rendering remote from the display hardware. Merely drawing some text, even if it is antialiased, shouldn't ever require bit blits over the network.

  9. Re:One and the same on Why Whistleblowers Can't Get a Fair Trial · · Score: 1

    I don't think I have ever heard of a case where a person discovers wrongdoing, goes to his superior about it and has his superior actually take meaningful action.

    Technically speaking, you wouldn't hear about those because they're normally dealt with fairly quietly and at an early stage. Occasionally one escalates as far as the law, and you can see reports of this sort of thing in your local press from time to time if you care to look. It's all normal and very dull.

    It also breaks down when it is the superior doing the wrongdoing or the system within which they work is itself at fault. Which appears to be the problem in the Snowden affair.

  13. Re:Cool science coming... on CERN Antimatter Experiment Produces First Beam of Antihydrogen · · Score: 2

    You are mistaken. Antimatter cannot have the opposite gravitational sign as matter in general relativity. If it did, it would be possible to distinguish between an experiment performed in a gravitational field (e.g. standing on earth, antimatter released in a vacuum chamber would "float up") and an experiment performed in an accelerating rocket (e.g. antimatter released in a vacuum chamber would be "left behind" and would "fall down").

    It's an assumption that that is true, not a proven thing. We don't know if the gravitational mass of antimatter has the same sign as the inertial mass of antimatter, nor do we know why those two quantities have the same sign (and value) as each other in normal matter. Accumulating enough cold antimatter to be able to measure gravitational effects at all is hard, as is explained elsewhere on this thread. Without the experimental evidence, no amount of armchair theorising is going to be truly sound.

    "Ad blockers try to make a distinction between content elements and advertorial elements. We make that distinction impossible,"

    So long as you're hosting your ads off-site, or even on a local (ad.example.com) server, we'll be able to block them.

    There are ways around that (e.g., integrated proxies) but they make things much more expensive for the people hosting the desirable content as that's usually as close to a shoestring operation as possible (and has to be, given the low rate of return on having ads in a site). If the advertisers want around blockers in ways that are hard to prevent mechanically, it's going to raise the amount that they have to pay a lot. That'll make a lot of the low-rent crapvertising completely uneconomic.

    I think I might be OK with this. For now.

    Blowing the cover off the manhole is easy, the explosion could have been triggered a long way off underground. Plus ethane is slightly denser than air, so it's unlikely to vent off much through the manhole cover. You'd probably need to push air through to disperse the gas.

    Hierarchic thinking has infested Computer Science for decades. The entire Object Oriented Programming paradigm was founded on hierarchy, with Inheritance defined as from one parent only, and many not too sure if multiple inheritance is a good idea or needed. That the notion of inheritance even has to be qualified with that word "multiple", because it implicitly means single otherwise, is a barrier to thought. Trees are useful data structures, but they aren't the ultimate, universal data structure that can succinctly describe all other organizations of data.

    There's a lot of foolish programmers who think that because they've got inheritance available to them, they've got to use it. It's the If All You Have Is A Hammer principle. Delegation/composition is much more useful in practice (and can express arbitrary graphs just fine).
