Comment Re: Deciding when to correct a human (Score 1) 22

I think it's even more interesting, in that one or two humans have to decide whether to question a call, and they have to identify calls that were wrong, not just ones they want to overturn, and they don't have a great angle to figure out what the algorithm would do. I think it's going to be fun to see batters try to do the ump's job, while standing to the side and considering swinging at the pitch.

I think the real issue is warm parts of China selling to cold parts of India without including the features that aren't needed near the factory. We know lots about battery chemistry, but rural farmers have had more immediately relevant things to know about up to now and don't have a good source of information on this new thing the government is pushing, so they skip things that sound like luxuries and end up with something inappropriate for their purpose.

Comment Re:The domination of the personal device (Score 2) 81

That just means Google is now operating in exactly the same manner that Microsoft used to be when they had dominance over consumer device operating systems. Google now has dominance in the mobile market with Android, and is using that to shove Chrome down people's throats. Personally, the first thing I do with any new phone is download Firefox, just like I did (and still do) with new computers. As the statistics show, though, the vast majority of people don't bother to do that so whatever is the default is what they use. The right and fair thing to do would be to stop them from abusing their monopoly power by offering a choice of browsers at time of install, and not favor their own browser in any way. That would have been the thing to force MS to do as well back when they were being sued for abuse of monopoly power after taking down Netscape with the same tactic. Unfortunately, it didn't happen then and it isn't happening now either. So, Google will continue to dominate the market unless and until some other highly disruptive technology comes along to unseat the current smartphone market and gives another player a chance to enter and eventually dominate the market in a similar fashion.

While I accept your point, I feel it necessary to add that the problems you are referring to, excessive cost and poor quality, are American problems. The rest of the civilised world has low cost or free healthcare and doctors that aren't ground into apathy by the capitalist machine.

So the rest of the world would like to be cautious because we like what we have. Unlike Americans we do have something to lose.

Submission + - Another large Black hole in "our" Galaxy (arxiv.org)

RockDoctor writes: A recent paper on ArXiv reports a novel idea about the central regions of "our" galaxy.

Remember the hoopla a few years ago about radio-astronomical observations producing an "image" of our central black hole — or rather, an image of the accretion disc around the black hole — long designated by astronomers as "Sagittarius A*" (or SGR-A*)? If you remember the image published then, one thing should be striking — it's not very symmetrical. If you think about viewing a spinning object, then you'd expect to see something with a "mirror" symmetry plane where we would see the rotation axis (if someone had marked it). If anything, that published image has three bright spots on a fainter ring. And the spots are not even approximately the same brightness.

This paper suggests that the image we see is the result of the light (radio waves) from SGR-A* being "lensed" by another black hole, near (but not quite on) the line of sight between SGR-A* and us. By various modelling approaches, they then refine this idea to a "best-fit" of a black hole with mass around 1000 times the Sun, orbiting between the distance of the closest-observed star to SGR-A* ("S2" — most imaginative name, ever!), and around 10 times that distance. That's far enough to make a strong interaction with "S2" unlikely within the lifetime of S2 before it's accretion onto SGR-A*.)

The region around SGR-A* is crowded. Within 25 parsecs (~80 light years, the distance to Regulus [in the constellation Leo] or Merak [in the Great Bear]) there is around 4 times more mass in several millions of "normal" stars than in the SGR-A* black hole. Finding a large (not "super massive") black hole in such a concentration of matter shouldn't surprise anyone.

This proposed black hole is larger than anything which has been detected by gravitational waves (yet) ; but not immensely larger — only a factor of 15 or so. (The authors also anticipate the "what about these big black holes spiralling together?" question : quote "and the amplitude of gravitational waves generated by the binary black holes is negligible.")

Being so close to SGR-A*, the proposed black hole is likely to be moving rapidly across our line of sight. At the distance of "S2" it's orbital period would be around 26 years (but the "new" black hole is probably further out than than that). Which might be an explanation for some of the variability and "flickering" reported for SGR-A* ever since it's discovery.

As always, more observations are needed. Which, for SGR-A* are frequently being taken, so improving (or ruling out) this explanation should happen fairly quickly. But it's a very interesting, and fun, idea.

Submission + - Surado, formerly Slashdot Japan, is closing at the end of the month. (srad.jp) 1

AmiMoJo writes: Slashdot Japan was launched on May 28, 2001. On 2025/03/31, it will finally close. Since starting the site separated from the main Slashdot one, and eventually rebranded as "Surado", which was it's Japanese nickname.

Last year the site stopped posting new stories, and was subsequently unable to find a buyer. In a final story announcing the end, many users expressed their sadness and gratitude for all the years of service.
