I would expect full self-driving to come through remote operation capability - at first a single person can remotely operate one vehicle. After some improvements it would be possible for a single operator to control 2 vehicles and so on.


That energy can be recuperated.


It's true that you could build a condenser and pump the steam through the next batch of water, but I doubt you will ever get anywhere near the efficiency you need to make it reasonable. I'd be incredibly happy to see any links that would prove me wrong, though!


The process is called Multiple Effects Distillation https://en.wikipedia.org/wiki/Multiple-effect_distillation

It is a commercially successful process. For example Hitachi have build 8 plants delivering a total of 8,600m3/day https://www.hitachizosen.co.jp/english/products/products011....


That's really cool. Thanks! I should point out, though, that I meant that I don't think you will get efficient enough to make solar power reasonable. You will notice that Hitachi's RO solution has higher power efficiency than the distillation solution. I'd be really curious to see how much power it actually uses, though... Unfortunately it doesn't say in their marketing material.


IANAP but this process will increase the entropy of the energy and result in it being more difficult to utilize


"Microsoft Solitaire has likely been installed on more than a million devices."

Probably billion, not million.


It's likely been installed on more than a million devices too.


Even on more than a dozen devices when you think about it.


At least two!


Correct. They say a billion later on in the article. That's a typo


"Microsoft Solitaire has likely been installed on more than one device."


An optimal implementation of Dijkstra's algorithm i O(nⁿ) in the number of vertices.


Just like Doom as well


> Anything that happens after the end of an individual’s reproductive years (perhaps also the period of raising the offsprings) stops exerting any evolutionary pressure.

This is definitely wrong. Individuals (e.g. grandparents or just random society members) can influence survival rates of other society members.

Some species(e.g. ants) even have sterile members that definitely exert evolutionary pressure.


I think you didn't take enough time to understand my point before being so "definitive".

Sterile ants do not exert evolutionary pressure unless they would attack weak queens before they are ready to reproduce. Evolutionary pressure (by scientific definition) is caused by things that reduce reproductive success in individuals or parts of population. Like a mutation that reduces fertility. Having the old individuals around might help relieve some of the pressure by infinitesimal amounts (helping raise offsprings) but that's about it. They cannot influence the outcome of a "defective" gene so they do not really drive evolution in any meaningful way.

Take this example. A genetic disorder that causes blindness soon after birth basically eliminates the individual from the population and the genetic defect along with it. Thus evolutionary pressure (genetic defect before the reproductive age) achieves the selection.

A genetic disorder that causes blindness at old age, any time after the next generation was raised, might also eliminate the individual but this doesn't matter as much. The gene already got passed along to the next generation(s). As long as it manifests only after reproduction then it does not reduce reproductive success, so exerts no pressure.

Or perhaps you want to take something like male impotence as an example. If humans were expected to bear offspring only in our 70s I'm certain Viagra wouldn't be a thing. Only the males that are still able to perform at that age pass along their genes, to the point where the males that can't are the exception.

I hope you can appreciate the difference in magnitude (many orders) between directly applying evolutionary pressure by removing the individual from the gene pool before the gene can be transmitted, and indirect evolutionary pressure via reduced support in society (which could conceivably affect reproductive success). For one, it stands to reason that solitary species or ones that do not form real societies would be completely unaffected by this indirect evolutionary pressure.


Reporter was claiming that warehouse was freezing cold to keep electronics of robots cool. It's total nonsense. These robots probably emit less heat than regular forklifts.

The only reason for the freezing temperatures is to keep foodstuff fresh.

Also datacenters underground is only a marketing trick (we keep you servers in a bunker). If anything it only complicates getting rid of extra heat (eg. problems with London underground [1] )

[1] https://www.independent.co.uk/travel/news-and-advice/london-...


Given that the article also has no information about the cause of the fire ("The firm has not yet commented on the probable cause of the blaze and the investigation could go on for quite some time") it's also fairly easy to read the earlier "electronics get hot" as trying to point towards a suspected cause.

As you say, it's total nonsense - even if the cause does turn out to be an electrical fire, it's unlikely to be due to insufficient cooling of the whole warehouse.


I don't she meant to suggest that improper cooling led to the warehouse burning down.

She implied that DC are built underwater/in mountains (true) often (false) because electronics get hot (true...ish). And then drew the conclusion that this is one of the reasons the warehouse is cold (false) on top of the obvious one:

> The temperature was to protect the cold food, I was told.


Just to plug-in - there are technologies that don't require hammering- suction buckets and floating wind turbines.


The most annoying thing is traffic is comming from google.

Lately google search results are full of such low quality results, computer generated text, etc.

Same applies also to YT - videos with 2x speed, inverted colors etc.

What is this? Can you provide some links to these kind of videos. Thank you.


Hight-carb here refers to carb-protein ratio, not high-calorie diet.


Statistically no one can stay on a high carb diet that isn't also high calorie.


I would like to see the statistics. I eat a high carb low protein low calorie diet because I like to fit my grocery bill in $15 a week. I would wager the opposite is true actually; if you're eating 1000 to 1400 calories a day and they're not mostly carbs, you're probably feeling terrible hunger pangs.

Most vegetables are carbs, milk and yogourt have tons of carbs (in the form of lactose), lentils are carbs, beans? still carbs, etc. I'm not sure how you can have a cheap low-carb diet (lots of eggs and ham? dissolving multivitamin and whey protein into avocado puree?).


Eat two eggs and three slices of bacon for breakfast, and I can go all day until supper without thinking about eating. Eat a big bowl of cereal or bagel, and I'm ready to murder somebody for a snack by 10 am.

That's the reality of most people's high-carb diets.


This:). I lost 25 pounds on Keto in over 9 months. Then relaxed my diet to gain about 7-9 pounds back. I went back to Keto Two weeks ago and down from 165 to 161.

I eat less than 20 carbs a day.

With 200 grams of protein and about 150 grams of fat. I feel great. Can go without food cravings all day. My CrossFit has improved and I have set 2 PRs in two weeks on weights.

I believe in low carb diets. And have seen them work for many folks at my CrossFit box.

I'm not sure the radiostation analogy holds. Radiostations can't claim copyright to the song.


So the "never have to come down" is ~100 days record which is held by project Loon?


~6 months is the current best, actually. [1] This is a development project; there's no reason to assume that the current record is a hard limit.

[1]https://en.m.wikipedia.org/wiki/Loon_(company)#Timeline


Loon balloons are helium, and helium gas is famously hard to contain, so eventually leaks out and the balloon comes down.

I don't see any way to make a balloon stay up forever unless you have a particle accelerator to manufacture new helium to make up for leakage...


> Loon balloons are helium, and helium gas is famously hard to contain

It's not like there are any better options? The only two practical lifting gases are hydrogen and helium. Hydrogen leaks even more than helium and is flammable, even though it is much cheaper and abundant.
