It is fantastic that space is becoming profitable and I very much hope Spacex and the like grow exponentially.

But it's hard to imagine space technology would advance faster if NASA and JPL suddenly ceased to exist. It's even harder to imagine space tech would be anywhere near as far along as it is now if they had never existed in the first place. Besides that, the Apollo program supported almost the entire semiconductor and even transistor industry for a decade. Our world today would be unrecognizably more primitive with out that.

And while "useful" military applications gave us the V2, and then the space race to build suborbital missiles capable of carrying nuclear payloads, the "socialist" non military NASA projects involve less city destruction or risk of nuclear annihilation. A future orbital arms race will presumably move some land based missiles into orbit and cut down crucial retaliation decision time to seconds. "Useful" though it may be, military expansion would be the kind of development best avoided

So China did not fall behind because of Zheng He, it fell behind _inspite_ of him. It fell behind because an overly restrictive, incurious, overly frugal leadership prematurely _stopped_ exploration, both government and private. A similar thing happen to Japan without ever having a costly initial government expedition.

Conversely, Norse exploration failed even though it which was low cost, benefit driven and not central subsidized. Overall, Europe was lucky in that it was so balkanized that a few countries were bound to send/allow ships into the unknown. "Lucky" also was that a gold filled North American blocked Columbus on what would have been a suicide trip across Pacific + Atlantic. Which trip, incidentally, was government funded.

> There's a matchmaking problem here.

Absolutely agree. We need an efficient algorithm for matching based upon common interests, agreeability, and politeness.

I wonder if matchmaking algorithms from video games would come in handy for this? I think the League of Legends queue algo would be perfect for this.
What banking services do these people need? Most banks offer mobile check deposit, and many offer a wide network of fee-free ATMs. Most of these ATMs don't take deposits, so that may be an issue for those who need it.

I use Ally Bank and they offer $10 reimbursement for ATM fees every month and they have a wide network of fee-free ATMs (at most 7-11s and a few other common stores). If you look harder, you can find accounts without any limits (e.g. Charles Schwab), and many credit unions support deposits in co-op ATMs (probably not helpful if there aren't any in rural towns). The only reason I go to banks is to withdraw cash in specific denominations for paying our baby sitter, but you can usually get the same thing if you ask nicely at a grocery store.

I don't see much of a reason why people need physical banks anymore. Withdrawals can happen with an ATM, deposits can happen in mobile or mail, and loans are increasingly available online. The only thing I can think of is business owners needing to make deposits and withdrawals frequently.
I can't think of a more literal example of survivorship bias.
More likely: "People who live 85 or more have more of the good things like health and safe environment which also makes them optimistic."

Sorry, meant transfer of learning, edited.

https://en.wikipedia.org/wiki/Transfer_of_learning

> Today, transfer of learning is usually described as the process and the effective extent to which past experiences (also referred to as the transfer source) affect learning and performance in a new situation (the transfer target).[2] However, there remains controversy as to how transfer of learning should be conceptualized and explained, what its prevalence is, what its relation is to learning in general, and whether it exists at all.[3]

You know, if anything coffee makes me more likely to shoot random texts to people, though.
The same is true in the US. Ally Bank automatically reimburses fees up to $10/month, and Charles Schwab reimburses without any limit. Each back obviously has its own network and policies for out of network withdrawals, but I can't remember the last time I actually paid an ATM fee (I use Ally Bank).

You are half right. Making those behaviors completely disappear from the codebase? That might be a challenge. Making them not show for the customers , ever ? That's a matter of adding a few display: none rules to the SASS, recompiling it and doing a quickfix release. At our company this would involve a frontend developer, someone who can do a release (not unlikely: me :) ) and someone from QA. If the law were on our tails, I would estimate less than a day to get this done even during Christmas holidays. I don't think we ever played the playbook in PagerDuty which pages frontend but we could. Even my phone meows rarely, phew! (PagerDuty has many hilarious sounds, my choice is the meow sound thus we practice meow driven development: I don't like my phone to meow desperately.)
It's a little weird to see a study about the effects of optimism control for depression...
I don't claim that's the case but there's at least one missile: (https://en.wikipedia.org/wiki/3M22_Zircon) hypothesised to produce plasma stealth (https://en.wikipedia.org/wiki/Plasma_stealth).

My understanding is that a plasma stealth object should be high velocity and be optically bright to visual and IR. I don't maintain an hypothesis that that is the case but if any of my airmen would see such an object I would definitely like to have a report on that.

The problems described in this article seem to relate to the rigidity of Japanese culture more than anything else. You’d be wandering into pretty fringe territory if you were to question that value of compulsory education in general. Children are immature and cannot be relied upon to make responsible decisions, which is why they have legal custodians up to a certain age. Any particular education system will have its own set of problems though, like the ones discussed in this article.

> Why bother forming friend circles with people you must talk to, when you can find friend circles from a larger pool with people you want to talk to?

Because this is how the real world works. Being able to get along well with people you didn’t select, or perhaps don’t even like very much, is an essential part of a functional society. Perhaps children aren’t likely to understand this, but shielding them from exposure to it isn’t really setting them up for success later in life.
> If you're using AWS you're better using the built in option available for the cli. The --query option (and often combined with the --output option) does this, and uses JMESPath.

Jq is so much more capable than jmespath that I find myself using jq on the json output of AWS CLI commands more than using the built-in query option. Sure, it requires another tool, but it’a often the best tool for the job.

Yes, and that history of chemical changes is punctuated by global mass extinction events!

Just saying, it's not like there's a law of nature that keeps Earth habitable for humans. We should be aware of that. I think you're shifting the goalposts -- earlier you seemed quite confident that there wasn't a period within hundreds of millions of years that wouldn't have been habitable by humans. Have I changed your mind about that?

I don't think anyone who worries about climate change as an existential threat is thinking of sea level rise, a few degrees C and a few hundred ppm of carbon doing us in. Those could make life quote difficult at most. But it's the feedbacks that might run away from there, which are very hard to bound. How quickly might a few hundred ppm become a few thousand, if methane hydrates start to off-gas? Etc.

How confident can you be that it won't happen, when the Earth has carried itself away before?

I've done things differently just out of boredom caused by doing a task, the same way repeatedly.

Example: I sometimes get tired of a particular food and tweak it by adding a new ingredient or eating it with something different.

>Edison was unlucky—he failed to invent fuel cells. The first comercially successful fuel cells were developed in the mid-twentieth century, long after Edison moved on to pursuing other ideas.

This is completely different from the "Edison never gave up and kept working till he succeeded" talks.
My impression is also that everything at universities are much more formal than they used to be. (This is based on my experience -- I've been tenured ~10 years at a state university -- and have spoken to older acdaemics about this topic.) I don't know why, and don't think there's a single cause. My guess is that in part universities have come to depend on federal grants and private gifts much more than they used to, for better or for worse: donors don't always give money without attaching strings, and federal grant-making has also become much more formal and bureaucratic. A second possible reason, related to the first, is that federal regulation (both those that deal with education and with research) have become much more complicated, so that a university now has many more employees who are not instructional faculty (tenure track, tenured, or adjunct), and governing from the bottom up is just not practical. Yet a third reason is the constant possibility of litigation -- e.g., related to tenure and all sorts of other things -- so for legal reasons processes like hiring and promotion are highly scripted, whereas they used to be more formal.

On paper. If Bezos were to liquidate everything he'd have lots of trouble getting that amount. Maybe a slow divestment, though people would also question that move...

> [...] and thousands of delivery drivers have to pee in bottles while making slightly above minimum wage

One solution is certainly legislative. I'm not so sure that will fix the problem though as prices and inflation will increase due to more money flooding the system.

Better access to high-quality education is something we should be providing. But that typically only helps the youngest.

I don't know what the appropriate fix is.

> [...] is the time when the guillotines need to come out.

Violence isn't the answer. Have all other avenues even been exhausted -- why is violence the one to jump to? Are you willing to go to jail or be executed for killing Bezos? I don't think so.

At the end of the day, people still aren't uncomfortable enough to want blood. This is just armchair anger. There are better, more productive ways.

If the situation were truly to deteriorate to the point where people were dying of starvation, then maybe we'll see violence. I don't think we're anywhere close to that.
Also dimming might also have some effects on the fauna too. I know it’s a small change but on a global scale I bet there would be some pathology for humans and other animals.

You beat me to this by 5 minutes. It seems pretty obvious that the path of causation tends in this direction, rather than the other. And even if there is a signal going the other direction, extracting it from the noise caused by "people who have health and financial stability" seems impossible, unless the sample group were all of people who have lived to at least 85 without having these traits.

An interesting technique
That’s because school is just a glorified daycare for parents who both work for corporations. The school in turn trains kids to work for corporations someday — and in the meantime stay out of trouble until the parents can finish their workday.

Many schools are unable to teach kids anything and try to just contain the troublemakers long enough for their parents to pick them up.
I made this assumption for many years, and yes, that cost would be high. I eventually discovered that, more often than not, everyone assumed that someone must have already investigated a particular hypothesis but if you tried to identify that "someone" it turned out that they didn't actually exist. After doing this exhaustive search a few times in a few different domains and coming up empty handed, it changed my perspective on the matter, to my great benefit.

Searching for evidence that someone has actually done the work is relatively efficient. It never fails to astonish me the number of times that everyone believes a particular bit of ground has been thoroughly tread yet, if I try to find concrete evidence that someone has done the work, there is no evidence that anyone actually has. There is a strong cognitive bias (I don't know if it has a name) where everyone assumes that someone else has already tried every obvious or reasonable approach and that belief is treated as factual.
Sure, those things are completely equivalent to taking a hallucinogen.
But those costs are much less than the network fees since they're done in bulk instead of per transaction. Credit card processing fees are ~3%, so for every $1k in sales, you pay ~$30, whereas going to the bank is a fixed cost and merely takes time and can be scheduled when it's cheapest to do. So dealing with cash scales well since it has a fixed cost, whereas credit/debit gets more expensive (compared to cash) as revenue increases.
I have been recently taking a break after a long hard project which took up most of my time. Now I pretty much do whatever I feel like from the start of my day. Luckily I have enough small, easy work to pay the bills while I figure out what I would like to be doing longer term.

The free school in this article seems to match what I'm doing for "work" now. The more strict, controlling school with controlling parents is a closer fit to what I was doing previously. Maybe it's the parents and the parent's system which is broken.
As far as I know, the last time anybody used science to help make a good UI was for Windows 95.

I am not following UFO information but I think I have only heard about them in my country (France) only twice in the last 15 years.

I heard about cases in the US much often. US are also probably 3 times or size (population) and 10 times (or whatever) military size - so maybe the numbers are consistent across countries.

I wonder however how much culture plays a role in the sightings. All UFOs in movies land in the US. You have Area51 and the extraterrestrial highway. You have Roswell and tranformers inside the Hoover Dam.

If I see a weird thing in the sky, UFO will be the 7th possibility on my list. Maybe in the US UFOs landing is business as usual for pepole ?

> Also keep in mind that the middle school you get into will have a huge effect on which high school you get to attend, which has a very strong influence on which college you get into, and thus effect your pipeline into the best companies.

This is not generally true. For public schools (i.e. ones in the public system, not private) your middle school is determined by where you live. There is no entrance exam until you are going to high school. For the prestigious schools in the private system, there are often entrance exams at every single level, but these are not common schools. Normally, once you get into one of these school you are pretty much set for life (often they even have a university equivalent system, though you have to write a comprehensive exam to get your eventual degree).

As for bullying, I worked in Japanese high school for 5 years. It was a low level school (we once accepted a student who score 0 on their entrance exam -- that's how low level). Bullying happened, but compared to the bullying I personally experienced in my high school in Canada, it was quite rare. In every case of bullying that I observed, the bullies were expelled. It may be that my high school was particularly stringent about bullying, though. Of course you can't catch all cases of bullying and a lot will happen outside of the school grounds.

I'm not sure what's going on with this report and I'm interested to learn more, but especially at elementary level I find it a bit difficult to understand. Most of the things that distinguish western school systems from the Japanese system don't really kick in until middle school. There really isn't a club system in elementary school and children come home around 3 pm. They don't generally go to school on the weekend. I've seen the curriculum and it's not appreciably more difficult than in the west (I once had an idea to learn Japanese by buying up textbooks on every subject for elementary school children and learning everything they did. It was quite fun!) Whatever is going on, I suspect it's not directly related to the school per se.

I will say that in high school, they are somewhat more accepting of absenteeism, at least in low level schools. I had a student who never once showed up before 11:30 in the morning and while he was frequently a cause of concern for the teachers, he was treated pretty carefully. So it is possible that absenteeism is just more accepted. I don't know. I mean if your kid didn't show up for a month at school, I think a social worker would be knocking on the door. In Japan, it would be the home room teacher from the school and they have a lot less options than that social worker. But like I said, I don't know enough to understand what's going on here.
Agreed, but just wanted to add the context that you get undefined values by trying to access uninitialised things such as out of bounds array elements, get on a map-like object with a key that's yet to be set, unset properties on a object, return value of a function that returns void, etc.

A lot of cynicism in the comments here, but having an optimistic outlook has been a boon throughout history in almost all accounts.

Good catch. His comments can be ignored based on his comment history.
Mentoring is the fastest way for one to learn or relearn first principles. Explaining an idea to someone requires that you speak to their level of understanding. Thus, explaining a complex idea to someone with understanding of only fundamental truths (novices), requires that you only speak in first principles. If you cannot, you will provide a bad explanation. When you eventually are able to provide a good explanation, you will know you have grasped the fundamental truths of the idea.
