Airlines do want to save fuel but the reality is that there are some easy wins that have not been tackled. Before take-off the taxi journey to the runway is under jet power when you could have a more efficient tow truck to take the plane there. Concorde was the worst, B52s excepted, 2 tonnes of fuel just to get from the departure lounge to the runway.

Then there is the final approach. The Space Shuttle was somewhat brick shaped but they could glide that down from space to land on a runway. Obviously the safety of fare paying planet trashers coming back from their cheap flight is paramount and the peace of those living under the flight path matters not, however, planes could land space shuttle style, gliding in with no fuel being burnt. After 3000 miles of journey this ten miles of coasting might be rounding error, but what if you could catch the jet stream and, rather than take an hour off the journey time, coast as much as possible?

If the external costs of cheap flights had to be paid for then I am sure these options would become as standard as 'stop start' is with today's automobiles.

Regarding batteries destined to explode, there are ceramic batteries that do not spontaneously combust, imagine if parts of your car/plane/bicycle used such materials, e.g. if the boot liner or bumpers were made of such a lower density battery but doubled up with functionality?

> Android's market share is irrelevant to Google because it's a loss leader

I disagree. Android market share is highly relevant to Google. Android is the platform where Google exerts its strongest ability to nudge/influence/cajole/incentivize users to use its money making services (e.g. search). If Android loses market share, Google loses money.

What's more, Android market share keeps Google in the game. Google pays Apple 3 billion each year to be included as the default search engine on iOS.

https://www.cnbc.com/2017/08/14/google-paying-apple-3-billio...

What would happen if Google did not have Android at all? What alternative would it have to paying Apple (and any other company with a competitive mobile OS) an ever-growing share of its search revenue? How would Google compete against Bing and others if, instead, Windows Mobile had Android's market share? Google would be in a weaker, less profitable, position.

The driving reason Google bothered to create Android in the first place was to stay relevant in an economy which was transitioning away from desktop and toward mobile.

It is easy to argue with success if you could prove it was due to cronyism. :)

I don't see how cronyism could create catchiness at all but cronyism could account for the perception that only two people can do it when the actual number could be a much highe.

It appears there is indeed a link between short/long sleep and mortality. As you said, the possible causes are usually not reviewed. This concerns me as I do sleep 9h+ on average. (But then again I do have an eye-illness that require a lot of concentration to overcome)

If it was academia we were discussing, then yes share all the things. But OP is asking about things which can be commercialized.

Sadly science funding in the US is an absolute shitshow and science costs money so...

I think you should consider this from the position of a researcher with no funding sitting on valuable ideas. Commercializing that idea can fund other research they want to do. So even from the perspective of wanting science to be free and the common heritage of mankind, a researcher can do more science by capitalizing on a valuable idea.

It's kinda shitty, but science doesn't take place in a vacuum, researchers have to eat.

I get where you're coming at, but I just don't think it's realistic. You can't just ignore incentives.

From a December 2000 NY Times report,

Shares of Dong Ah surged 41 percent this week, to 410 won
(33 cents, United States) on Wednesday. Today, the Korean
Stock Exchange halted trading and ordered the company to
provide an explanation on Friday.

The run-up in the stock came after local media reports said
that the venture, the Korea Ocean Research and Development
Institute, had discovered a warship of the Imperial Russian
Navy, the 6,200-ton Dmitri Donskoi. ....

...

Sergei Klimovsky, chief of scholarly research at the Central
Naval Museum in St. Petersburg, told Bloomberg: "As far as
we know, at best, there might have only been some gold coins
on board to pay the salaries of officers. But there was no
hoard of gold, and to send a large amount of gold by ship
from St. Petersburg to Vladivostok is ridiculous. It would
have been safer to send it by rail."

He should have made it open-source rather than rely on Apple. Most of it had to be re-written anyhow between demo and final product, as I read it.

Worse: Some of the players have their interests exactly the opposite of other players. In particular, the doctors want to get paid, and the insurance company makes money partly by finding ways to not pay doctors. So the insurance companies pay people to find ways to not pay doctors, and the doctors pay people to find ways to get the insurance companies to pay. (Almost?) all of those people, on both sides, are a net lost to society as a whole.
This is actually really good.

I've seen more therapists in my lifetime than I care to admit. But something like this would have helped a lot when I was starting out.

The casual approach does a really nice job at breaking things down and explaining parts of the process, without feeling like it's being dumbed down at all. It makes it feel very approachable, which is very welcome, given how daunting it felt (at least for me) starting out.

I cracked up at "My therapist is dull and doesn’t laugh at my cat memes. Should I keep seeing them for therapy?".
Propping up useless jobs is only unacceptable to some when it is blue-collar jobs in red states(eg steel and coal).
That is technically insurance fraud. As a provider, when you accept insurance from a specific company you sign a contract that says you are required to accept that insurance as payment if you see a client who is a customer of that insurance company. You cannot hold specific "insurance" and "cash pay" slots. A large practice in Boston is being investigated for this right now, and it might put them out of business.
> there's broad agreement that people with more life experience are often better placed to offer help.

Broad agreement among whom? As with MDs, I would expect several complex trade-offs. Particularly between the value of medical (and life) experience against the value of being trained with the current science and treatment methods. For therapists I would also expect more significant trade-offs due to the difficulty of building strong therapeutic relationships across large age differences for some patients. Are you aware of any studies on the issue?
Can you link to published research indicating that there is any correlation between therapist age and patient outcomes? Many people come to the helping professions later in life, and time spent practicing is the just about the only factor that counts for behavioural therapies (with the caveat that therapy outcomes are a difficult thing to measure).

The reason that health care costs rise in almost all countries is that we are doing something wrong.
The question is what?
Can it be that doctors who do not try to find the root causes of diseases have no solutions ?
Can it be that doctors who prescribe drugs to suppress symtoms cause problems in the long run ?

Cancer is a disease with high costs where a lot can be gained.
Watch a documentary about Dr Burzynski who has a cure for various types of cancer: https://www.youtube.com/watch?v=rBUGVkmmwbk
The documentary shows how officials and the National Cancer Institute work against him and hence continue the high cost.

On websites like https://drhyman.com and https://www.chriskresser.com you can find doctors who explain a lot about root causes of diseases and how to cure oneself. If all would read these sites the costs for health would drop more than 50%.
There used to be companies like that. Unfortunately, the market for that is so small that it simply isn't worth it and they all died.

Humans are also exceptionally good at storing fat while also saving energy the moment someone misses a meal. There is a lot of research indicating regular fasting is actually beneficial to ones health, which in context would seem to only make sense if we were adapted to regularly encounter times of poor food availability. With people relying on stored fat from gorging on foods from better times and what you could find while traveling instead of dedicated forging or hunting. Once you encounter a better area with more game and natural food sources you stop again for a little while.
This isn't a realistic scenario. If Google "stopped licensing Android", most OEMs would fork it at least initiating. Additionally, if Google were to move solely into the Pixel space, it would fail, overtaken by Samsung and other OEMs which know how to run a hardware business. Apple will continue to be a niche player because they like it that way, they aren't a threat and never have been. And without the big Android bully in the picture, it's likely new Linux-based OSes would find a place to flourish. Microsoft would probably reenter the mobile arena as well. You are forgetting there are dozens of manufacturers who all have large mobile phone businesses, and they aren't going to disappear because Google is forced to comply with the law.

There is no scenario where Apple becomes a big scary monopoly that wins everything. That's what Google is, and that's why they're being fined.
That's funny, the other day I said machine learning is the offspring of chaotic environments.

I think it is more sides forming. Folks feel they are either on the side of white-collar or blue-collar. I would love to see a numbers run of the data to see if there are actual patterns.

Ultimately, I think all jobs are on the table as something that will go away someday. That day is a long way from now, though.

One of my favorite tweets from recently was in a theme of "things in your industry that are obvious, but folks out of the industry don't realize." The tweet was basically, "every piece of clothing you see was stitched together by a person." Basically, we get the impression that automation will be the big destroyer of jobs, but there is still a long way to go in that path. And, when it comes to it, white-collar jobs are probably more susceptible to automation than others. Consider, how many secretaries are there nowadays? Clerks? Data processors? I don't think these jobs have actually disappeared, but I do get the impression that they have drastically shrunken.
Reading that timeline was quite a trip. Humanity is really just a tiny blip in the grand scale of time.

They don't talk much about AI and other synthetic replacements for humanity. Maybe it's just too difficult to extrapolate.

One can guess, though, that long before another 10,000 years have passed, we will have developed artificial beings that are billions of times smarter than we are.

By then, we probably will have augmented our minds and bodies to the point where we are vastly more intelligent and powerful as well, so perhaps we will survive in some form or other.
Windows 10 and Windows Server 2019 to Support True UTC-Compliant Leap Second
Compared to a optimizing compiler, a fresh implementation for a language would probably also be thousands/millions of times slower, unless the codebase implements the optimizations itself.

And then you end up speeding up the compiler to reach a decent state, to speed up the code

But time to reach initial compiler is much faster with a jet-based one (there's barely anything to the language).

and then you end up adding jets to reach a decent state

I'm not sure there's a significant difference in this regard. The main question, I think, is which is easier/simpler/faster to optimize into a proper state, and in the case of compiler optimization being better, if its sufficiently better to beat the ease of initial implementation for a jet-dependent language
Hah. I have a short perl script that trivially tests individual components of gitlab pipelines (parses the yaml, extracts the script components, saves them to a temp file then executes the temp file as bash script). The code is short but a little contorted. Works well though. Will be releasing into the wild in a couple of months.
> Rooting isn't exactly using the system as designed.

Rooting is very much using the system as designed. Google supports it and provides tools to enable it. Some apps on the Play Store require it. Does that mean everyone should root? No. Does this have any bearing on the fact that the recovery image should not be modified when rooting? No.

> They even (ab)use this to make seamless updates by creating a second /system partition, writing the update to that, then swapping over on next restart. If something goes wrong, they swap back to the first system partition.

If Google could provide a better way to root then this wouldn't be an issue. That they provide a suboptimal method isn't a defense here.

> In a normal Android system /system is read only unless mounted otherwise (which only really happens during updates).

I like how you contradict yourself in the span of 2 comments. First you said "Removing that app from the system partition won't give you more usable space without repartitioning", now you say that space is usable for installing updates. You just refuted your own point.

> In this manner, the /system partition is NEVER written to outside of creation.

In other manners, it IS written to outside of creation, and this is clearly due to the way they designed the system, not because modifying /system should actually alter the recovery image.

> Rooting is literally sidestepping this entire process to take full control over the system and mount /system as writable.

Yes, that's what it is, because it's necessary for some apps to be able to do what they do. The fact that they don't provide a better mechanism isn't a defense for the consequences of providing a poor mechanism.

> Sure, you could probably make a /recovery, /system, and /data all different partitions, but now you are roughly doubling the amount of data on the disk for not much of a reason.

That it's "not much of a reason" is very much your quite-subjective opinion. And there are better solutions than what you proposed here. And PCs already do this. But at this point you're changing the subject -- a reduction in space usage would not make your claim that "that's literally what disabling it does" any more true. It's simply false.

Preventing validator set manipulation is an important part of sharding research. Part of the solution is getting good random numbers that can't be manipulated, and there are several approaches for that.

Cross-shard communication gets complicated. There are some ideas for it, but that's several years down the road. It'll still be a big step up to have lots of shards, each with the capacity of the full blockchain today, sharing the security of all of them but not getting swamped with traffic if something gets really popular on another shard.
That's the current local optimum for phone manufacturers. The anti trust regulations exist, in part, to help prevent companies from forcing a local optimum that ensures no one ever tried something different, and thus forces the industries to keep improving.

If the OS was so good on it's own then google would not need these licensing terms to maintain market share.

Very informative, thanks!!!
I'm glad the EU has fined Google 5 billion. It's finally going to make them reassess their Android open source strategy and hopefully come to the inevitable conclusion that open sourcing Android was a mistake. Hopefully, they don't repeat this same mistake with Fuchsia.

As for Google Mobile Services (GMS) - I believe the smart thing to do now would be to start charging OEM's, that sell phones in the EU, to license GMS at 5% of the cost of the device or $50 - whichever is lower. If OEM's don't want to use GMS they're free to ship their own services.
