And by the time the first "warning" was raised- the girl's camp was under water. The "emergency" wasn't raised until hours later.

And the republican legislature (including the repp for Kerr County) voted down the flood siren warning system. He says now that he "might" have voted differently.

The emergency alerts on the phones do not discriminate. They play that incredibly nasty noise.
And they also play it for amber alerts--- for kids who were kidnapped over 100 miles away -- 24 hours a day.

One you get woken up for a watch or an amber alert at 3am out of a sound sleep, the alerts get turned off.

Is that even with all this solar, wind, etc.... China *still* must build more coal plants even tho we are finding out their population is smaller than we thought.

In time, alternative energy will destroy demand for coal but for now, the projections are still for more coal plant by 2045.

I'm hoping they are wrong and solar/wind comes online faster. It's cheaper than coal but they simply can't produce and build it out fast enough globally.

And it's not just kids (won't someone think of the children)...

In Texas, we can get a half dozen "watch" alerts a day when storm systems are moving through.

That's *POINTLESS*. If your alert system is sending more than one message a day, you probably didn't set it up well.

And worse, the watches usually mean "stay at home, avoid getting caught in deep flood waters" and not "leave your home because floodwaters over your roof will be there in under 90 minutes."

And it's not even just amber alerts. You can get a half dozen "watch" alerts from a fast moving system *per day*.

At that level, "watch" alerts are useless. Especially since in most of texas they mean, "don't leave home or your car may be flooded out" and not "leave home- your home will be flooded out".

And the short staffing of the service in the U.S. due to Ham-handed layoffs this year did not help.

Global population will begin to decline in 2080.

However, the population of people 40 and under *has already peaked* and is declining. That means *not enough people working* to pay for benefit programs for people over 60 starts *today* .

So you are not having kids-- big whoop. Basically you are saying, "after me the deluge"

Population growth is occurring because of improved medical care and longer lifespans. But having 5 billion seniors, 2 billion adults, and 1 billion kids isn't going to be healthy.

I'm going to move on now. I can tell you are a flat-earther type. Further discussion with you is pointless.

Comment Important, but uses slowness of Turing Machines (Score 3, Interesting) 37

YouTube lecture on this by the discoverer, Ryan Williams
Ryan Willaims's paper, "Simulating Time With Square-Root Space
This appears to be based partly but largely on Tree Evaluation is in Space O(log n * log log n)" by James Cook and Ian Mertz (2023 colloqium, STOC 2024 conference).

I'm just a programmer who has spent an hour or so looking at this, so please take the rest of this post with a grain of salt.

I get the impression that Professor Williams's result so far, already a tool for making progress about which computational complexity classes are the same and different, has the limitation of relying on how slow Turing machines are at accessing memory, based on the mention at 18min:50sec into that YouTube Video of how the space savings degrades for a Turing machine with tapes of more than one dimension. If I understand correctly, for such Turing machines, an algorithm with running time bounded above by time T(n) for any input of length n, the space used by this potentially much slower space-saving simulation is bounded by O( ( T(n) + log T(n) ) ** ( 1 - (1/(D+1))) ). I'm using "**" as exponentiation, so the exponent means square root (that is, exponent 0.5) for a one dimensional (linear) tape, two thirds power (exponent 0.66...) for a tape that is a two dimensional surface, 0.75th power for a three dimensional tape, and, so far, no known savings for a tree shaped tape, although I suppose that that three dimensional limit does ultimately apply to real world data storage systems.

Until you accept the reality that it's too late to fix/solve the problem, you are not dealing with reality. Once you are dealing with reality, you can start making rational decisions about what actions you can take to improve your personal situation and to keep from making things even worse than they already are.
