Comment Re:Tablets/Phones are complementary, not replaceme (Score 1) 103

There might be a merger in the sense that tablets become the screens for laptops. The laptops a dock of sorts. When detached the tablet runs a tablet OS like iOS. When docked it goes into screen only mode and function as an external GPU and display, the laptop running a desktop oriented OS like macOS. Note some iMac's can be put into display only mode. But this will only happen if there is a cost savings somehow. I'm not sure there is.

I'm fairly certain there isn't. Asus has two current models, one of which is focused on gaming, Dell has one, Lenovo has a couple which happen to be Chromebooks, and of course there's Microsoft's Surface. The Surface Pro series is now a decade old and it's not exactly burning up the sales charts. These things have existed for long enough that it's pretty clear that the design results in an inferior tablet and an even more inferior laptop, not least because of the horrible infestation of tablet user interfaces into what are nominally laptop operating systems. Both Microsoft and GNOME have pushed this idea and anybody who has had to suffer with using them can tell you that convergence does not work.

They have their uses, but detachable laptops are firmly a niche product.

Comment Re:Why Sand? Concrete? (Score 4, Informative) 64

From the summary, it seems clear that the sand is being extracted for industrial purposes. The most obvious one would be to mix with cement to make concrete.

It most definitely is not being used for concrete. Ocean sand is so rounded off that it makes exceedingly weak concrete. There was a scandal about it in China, and some collapsed buildings. River and ocean sand is wholly unsuitable for structural cement.

The vast majority of dredging is to keep shipping lanes open. Barge traffic on the Mississippi river accounts for half a billion tons of freight every single year and it's neither the largest nor the busiest river in the world. The streams and smaller rivers that make up the Mississippi river basin carry tons and tons of silt and sand into the river every year. The Army Corps of Engineers is in a constant battle with the silt accumulation. More beavers on small streams would help with that, to slow down the water farther upstream and allow the silt to fall out on the bottom of tributaries, but the North American beaver is an indiscriminate, if persistent, engineer, who will flood roads if not supervised.

Make it a shitty place for young people to live and no one will want to live there who is under 50...good luck running a tech company if no young people want to work in your state.

I work for a tech company with very few young people. Our hourly bill rates are eye-wateringly high. And people pay them, because we deliver.

Youth is not required to run a tech company. It just makes it cheaper.

Looking backward in time: Because DNA is not infinitely divisible, a person can have a genetic 9th Great Grand that contributed zero DNA to their DNA -- It takes just 200 years to lose the thread of DNA for non-Y/non-MT DNA for some ancestors.

Looking forward in time: even with modern medicine, etc, most lineages die out within a dozen or so generations -- most people living today will have no descendants in 12 generations. And as noted above, at 12 generations even if you have direct descendants there is only a 1:7 chance that they have any of your DNA except for the cases of direct male/female lines which comprise just 1/4096th of possible descendant bloodlines at 12 generations.

That's all well and good but we're not talking about individuals here. We're talking about the entirety of the human genome. The likely coefficient of relationship between you and me is somewhere between 13th and 15th cousin, and yet on average, you and I share 99.4% of our genes. DNA is not infinitely divisible and it is also not infinitely variable. Human DNA in particular is unusually homogeneous compared to other species on Earth. And yet, because there's so very much of it in our chromosomes, that leaves some 20 million base pairs that are likely different between you and me. Many of those differences are functionally indistinguishable, resulting in the same proteins for both of us, but they're there, and mathematicians can sling equations around using such numbers.

Whether or not those equations are justified is an ongoing argument. We still have a long way to go to determine what all of the 3.2 billion base pairs in the human genome are doing, but one thing we do know is the rules of propagation are complicated and not purely random.

"It is a bit like inferring the size of a stone that falls into the middle of the large lake from only the ripples that arrive at the shore some minutes later," said Stephan Schiffels, a population geneticist at Max Planck Institute for Evolutionary Anthropology in Leipzig, Germany.

So.... really accurate? Characteristics of a Linear Plane Progressive Wave. The velocity field equations are on page 8. (I'm not quoting all the Greek letters in the formulas because Slashdot.) This is coursework for college kids. It's called Marine Hydrodynamics and it's an incredibly well-studied field. And of course if you have stupid amounts of processing power you can always run a Navier-Stokes equation simulation in reverse. That's a fairly good analogy for the statistical analysis of the whole human genome that is done for the results in papers like this one and how it is not like inferring the size of a stone from the ripples. We have equations which describe the behavior of water in a gravity field to a nicety. We lack similar equations for describing the propagation of genes in a genome.

More such incidents than Toba at 75k years ago?

Quite a few more. We've been repeatedly genetically bottle-necked. It's one likely explanation for why there are such distinct human phenotypes. Isolated groups of humans who suffered severe reductions in genetic diversity would rebound looking very similar to each other and much less similar to everyone else.

Basically the human "races" are just like dog breeds, with distinct phenotypes induced by external forces, yet we're all still the same species.

I still can't stream Twins games in their local market. The asinine NFL blackout rules are a different topic.)

Never forget the three sports-ball leagues in question are cartels legally exempt from US anti-trust law. Great gig if you can get it.

The team owners are still convinced that blackouts serve to drive in-person attendance at their games. It may be pure wishful thinking on their part, but they're clinging to it with both hands. Plus they have ancient contracts with nearly as ancient local broadcast stations that must have had 50 year terms or something for them to still be honoring them. If I were them I'd have let those exclusive contracts expire a decade ago, but apparently they haven't done that either.

In any case, the revenue streams of sports-ball are many and varied and subject to a Byzantine tangle of contracts. There's no sanity to be had.

You say life will survive. Yes, certainly. But humanity won't if we are in such a disaster.

Why wouldn't we? We've already survived ice age ice sheets which reduced our numbers to a bottleneck so low it's visible in our gene pool 10,000 years later. We've demonstrated resilience to extinction events better than many hundreds of thousands of other species, and we have demonstrated our ability to live and reproduce in every land biome on Earth, something extremely few other multicellular species can do. For a land animal, we're the best there's ever been.

We'll never beat sharks, but they had a head start.

The reason most graphs only portray the last 200 years is simply because everything earlier are _estimates_. Obviously your claim is a complete fabrication.

That cuts both ways. All claims that the current rate is unprecedented are complete fabrications. There are no proxies outside of the historical record with sufficient granularity to justify that claim. Decadal fluctuations in temperature are invisible even to tree ring proxies, swamped by fluctuations in rainfall which do not correlate with temperature. Anything earlier than 200 years are estimates and the error bars on those estimates are bigger than the current fluctuation.

The XKCD plot in particular is one long wild-ass guess of approximations based on so many assumptions that a crystal ball would be as good. That plot boils down to "When there was a lot of ice it was cold. When there wasn't any ice, it was warmer."
