Comment what happened to the Voronoi polyhedrons? (Score 1) 40

Last time the bird flock was mentioned it was about how a flock flies past an obstacle without colliding. Something about each bird maintaining its position by maximizing the distance to its nearest neighbors. The math would work out such that each bird would form a vertex in a Delaunay tessellation and the "space" associated with each bird would form a Voronoi polyhedron.

I was kind of scared. You know, you spend all your life learning computational geometry and suddenly a flock of shearwaters or starlings show up and solve the same problem you have been solving for decades. You are given the pink slip and be replaced by a flock of bird brains. Man! that would suck.

But I am glad now, the birds are after bigger prize. No stupid engineering and mesh generation for them. They want pure science and may be they are after the Nobel prize. Glad they have moved on to simulating the liquid helium. Good for them. I think next thing will be they have solved the Cauchy-Riemman integral and they have a deterministic solution to Shroedinger's equation. They are going to finish off with a solution to Navier-Stokes equation with k-epsilon turbulence modeling.

Comment India has disputed borders too. (Score 1) 96

I have seen numerous Govt offices in India with a rusted metal sign saying, "Photography prohibited". But cut them some slack too, routinely attacked by terrorists looking for soft targets.

Also the border is disputed with Pakistan and China. Since Pakistan has been the "ally" of USA since 1950s, and India kept dallying with USSR all those days, almost all the American magazines will carry maps that show disputed parts of Kashmir as part of Pakistan. I have seen so many Reader's Digest, Time, National Geographic, Life mags with maps of Kashmir region stamped with, "This map does not agree with the official map published by the Surveyor General of India. No significance may be attached to the differences published here. " (quoting from memory, actual wording could be even more bureaucratese ).

Comment Looks like it is market opportunity. (Score 1) 544

I too like slide out keyboard and I like seeing more of the screen while typing.

But are we so dependent on the manufacturer for this? Someone can design a compact bluetooth keyboard. With some kind of harness/clip to slide in any smartphone. Or make it part of a slide out or fold out phone case. Almost all the people I know buy a case for their phones. I think Steve Jobs was probably the only one who used a naked iPhone. I see people putting really horrendous looking cases. Would these guys buy an after market Hummer body and strap it on to their Corvettes? Well that is a different rant. I use a fold out leather wallet style case, to store a credit card, a bus pass and my driving license along with an android phone. My wallet has gone into some deep recess of my backpack. I rarely need it.

Anyway if there is as much demand for it someone would be stepping in to fill the need. One good thing, this keyboard might work in the next phone, at least one part of the phone/keyboard gets an extended life.

Comment In conclusion... (Score 1) 281

Finally, we see a big limitation: This data reveals only correlations, not conclusions. We are left with at least two different interpretations of the sudden spike in “iPhone slow” queries, one conspiratorial and one benign. It is tempting to say, “See, this is why big data is useless.” But that is too trite. Correlations are what motivate us to look further. If all that big data does — and it surely does more — is to point out interesting correlations whose fundamental reasons we unpack in other ways, that already has immense value.

And if those correlations allow conspiracy theorists to become that much more smug, that’s a small price to pay.

And the cost is going to be paid by some company or the other for the benefit of some class action house or another.

Comment Graph is search results, not speed measurements. (Score 3, Informative) 281

The methodology of testing the hypothesis is to look for google searches about "iphone slow" or "samsung slow". Assumption made is if people search for "iphone slow" Apple might have done something to slow down iPhones. The control group is Samsung which has the same motive as Apple but not the means because it does not control the OS.

It is a big leap, there could be various other explanations of varying degrees of malice. As the new release comes through, bug fixes for older releases are put on back burner, apps are changed and tuned to take advantage of new version run slower in older version.. Or the way graphics subsystem is organized in iOS might have different bottlenecks based on the display resolution. So as new releases come in, default sizes for buffers and hashtables might change deep in the OS slowing down older apps.

And if you are going to postulate "Apple might slow down older versions deliberately", why can't you postulate, "Google might spike and skew the history of the past searches to make Apple look bad"?
