> you annotate each link with the latest date when it is guaranteed not to be expired

If I were paying someone for access to such an API, I would do everything in my power to change providers. Tracking link expiration would be a terrible developer experience. Such a thing may be a sound design for a system, but it's not a good design.

Providers like Twilio and Stripe have been largely successful because they've aimed for making developer experience as non-sadistic as possible.
Sure, but US hospitals are also known to charge up to 1000% more then a procedure actually costs[1]. That should be illegal.

The point is that an RNN or other language model describes a stochastic process which can be seen as a Markov process with state space given by the internal state of the RNN. This doesn't say anything about the ease of implementing or learning such a model. Just that from a purely mathematical perspective, they are equivalent in power.

My county recently changes up the rules on recycling. And it was a bit eye opening. They now will only take #1 and #2 plastic, paper, and aluminum only in the main recycling. Nothing else. They have nowhere they can send any other kinds of plastic to, at least for an affordable amount, because the entire region has nowhere processing it.

As for glass, they no longer take it for recycling either. They will accept it at the land fill, rather than in normal collection, to be crushed and used in concrete.

They also mentioned that food contamination is a huge problem, and can end up in entire batches of recycling ending up in the landfill instead. Because it is not cost efficient to sort it all out. Like most people think about cardboard pizza boxes as recyclable, however they tend not to be due to the grease.
What does the material efficiency for the gold look like? Is there room for improvement? Can statistical physics tell us something about purification effficiency? Is there room for improvement?

Or is it strictly of historical interest?

Can this decrease mercury pollution of the environment, especially by the poorer small scale gold refinement? Or has that already been succesfully replaced world wide?

I don't think there's anything super surprising about running on Java 8. I would be more worried if she said Java 4! Java 11, the next long-term support release after Java 8, came out late last year, and there were a lot more breaking changes between 8 and 11 than there were between 7 and 8. I had to a lot of dependencies, especially the ones that use reflection heavily (Mockito and Lombok come to mind!).

Meanwhile there are still young Java programmers who think that since 8 is the newest and sexiest thing, everything has to be written using lambdas and streams.
I mean, the 80/20 rule is seen in all kinds of places. Probably the top 20% [0] of men are involved in the 80% of heterosexual sexual couplings, with the remaining 80% of men being involved in the other 80%.

Where the stat kind of fails flat is that the same is true of the top 20% of women.

That said, the model (with no statement being made of how much that model reflects reality) being described is sequential monogamy. One of the top 20% men will continuously have one or two partners, switching them out for new ones; the rest of the men will only rarely get a partner; and women will fall between those two. Matching them percentile-to-percentile, the average number of new partners in some timespan for a given percentile for women will be larger for women than for men, up until some crossover percentile X% at which point men will have more partners.

I do think that if a person's primary mode of dating is through online apps, they end up with a skewed mental model of what dating is like. They are, however, already the main mode of new relationships being formed, and perhaps are still increasing in importance.

This is really good advise. Thank you very much for it. I will definitely keep this in my mind.

I suspect this is a form of delayed gratification, which is to say the gratification of achievement or disappointment of failure is delayed or momentarily avoided. This is bad. The cliche is: kicking the can down the road.

First of all, I doubt that high school is as competitive as the high school I attended which now represents the wealthiest mid-sized city in the US. The school is far wealthier now than when I attended although when I attended the high school football team was ranked #1 high school team in the nation. Our valedictorian received a full scholarship and invited attendance to Harvard due to the name recognition from the high school. Not many schools have this. The competition was real. The grade inflation was very real. The pressure put onto the school faculty by the parents (there was a lot of money riding this outcome) was extremely real. It is safe to say I have some perspective on this matter.

Delayed gratification is bad, because it is a developmental delay. Failure and disappointment are common events that occur in various magnitudes through out life. Teaching a child to accept and move past failure early is healthy. Giving everybody a trophy and pretending there is no failure has not proven to be developmentally healthy. Worse still the school doubling down on their bad decision by institutionalizing a form of grade inflation. This is the opposite of rewarding merit.

What is going to happen to the self-esteem of these students when they enter the real world and find they cannot perform as expected and that competition is a very real thing that mommy and daddy cannot save them from?
Here in (socialist/democratic) Sweden unions are prevalent for all categories of labour and have been for ages.

Really, breaking down the door of a journalist with a sledgehammer with guns drawn and then holding him in handcuffs for 7 hours because he reported on something they didn't want released? He's not even the person who leaked the report. I'd call it that overkill. I wonder what they told the judge who signed off on this waste of resources. You'd think SF had more crime issue that could be dealt with first.

"Arranged marriages were quite a success story"

If that were true people wouldn't automatically switch to love marriage when uncoerced. My experience of dating people from cultures where arranged marriage is still a (dwindling) thing tells me that no, they absolutely wouldn't go back to the days where it was prevalent.

"But they learned to make do and be happy in the end!" is not an argument. It can be used to justify literally any practice, because people always strive to be happy even in the worst conditions.

Seriously, what's with people wanting to coerce other people's romantic lives? When did we switch from "live and let live" to "the state should give me a girlfriend"?
I consider it institutionalized corruption when we allow healthcare providers to charge X to uninsured patients yet a tiny fraction of X to patients with insurance ... this distortion should be highly illegal ... this is how the insurance industry forces people to get insured ... healthcare providers cost of services to the patient should be independent of the patients level of insurance coverage
"But this isn’t soley about race, nationality or gender, you have to find a good mix also in terms of personalities, skillsets etc"

To my mind, this is the key point. It may be likely that a team with e.g. diverse skills/personalities will end up being gender diverse. But to assume that it has to be gender diverse, or that you can achieve a diversely skilled team by enforcing gender diversity seems to lapse into lazy gender stereotyping about how e.g. women's skills/perspectives are limited by their gender.

The title is definitely click-baity although the author is a bit more charitable towards books in content. I feel he is too harsh on books by judging them against unrealistic expectations. We can't remember everything we read from a book, much less explain it like a domain expert, but that is not the point of book reading. To me, books (at least the pop-sci books) are never about transfer of exact mental models, they function like a chisel to shape one's intuitions and understanding according to one's own disposition. Even though the aggregate effect on public tend to converge (for e.g, acceptance of evolution), it is hardly a case that everyone will have exact mental representation of a theory. Only place where the knowledge transfer can be (and should be) exact, is research and knowledge work domains (such as tech documentation). In such environments there is an incentive for the reader to engage with the material and the mental model of majority of the readers tends to be sufficiently homogeneous due to prior training. So the said shortcomings don't take place there.

Earlier, I too carried that feeling that I didn't remember much after reading and wondered whether there was any benefit from spending time on books. This turned out to be a cold-start problem because as more I read, cognitive structures started to form and I was more receptive to fresh ideas. New ideas, by means of comparing and juxtaposing against each existing ones, had a better chance of settling down in a proper cognitive framework and consequently a better chance of recall. For example reading Harari, Dawkins and Haidt roughly around the same period, strengthened my understanding of each's ideas as if they were all part of one giant discussion, although they were books on different topics and sometimes they contradicted each other.

Also it is important to engage in dialogue with a book, be it by participating in book clubs, online reviews or even simple note taking. Recently I switched to reading books on my mobile, I can't describe how much it has transformed my whole reading experience. My ebooks are littered with notes, questions and pointers which I know I will never let anyone see. Just an act of trying to compare or contradict an author in your personal note, can make you internalize the concepts and restructure your existing understanding. It is like solving a problem on blackboard. Now I prefer to buy books from Google Playstore even if I can get the same book for free from a local library. And I plan to post reviews on the books I read, by pouring through my notes and re-reading the important points from the books. In my experience, the second read is often more rewarding than the first.

> but it's not entirely deterministic because you don't know exactly when (or even in what thread) that "as soon as" happens.

But you do know when and where: it's at the exact moment the last reference to the resource was released, and in the exact thread that did this last release. In many cases, this will be a single place and thread; in other cases, it will be a well defined set of places and their corresponding threads, with the one coming temporally last being the one where the resource is freed (that is, the resource is held for as long as it's needed, and no longer).

> > it detects new garbage immediately after it becomes garbage, which keeps the resource usage at a minimum.

> Yes, but that comes at a cost to performance.

I was talking not only about memory, but also about other (more limited) resources like file descriptors. But yes, for memory there is a time/space tradeoff: reference counting minimizes memory usage, but for that it has to do more work by constantly freeing and allocating memory.

> Tracing indeed requires more memory, but it automatically uses that memory to reduce the cost of memory management.

Which occupies memory which could be used instead to reduce other costs. For instance, this extra memory could have been used by the operating system's disk cache.

I have often wondered if it would be possible to make a simple game of typing 3 or 4 digit sequences (similar to the dactylo typing games like "type the words before they fall to the bottom of the screeen"), and then find out if PIN code subsequences or digit transitions have a distinct timing pattern. If possible it would be very creapy if it would imply browser based games, or a keylogger, or your employer could extract your pincode from enough typing material (say in some spreadsheet)...
It seems pretty clear that the OP used "state" in a generic sense despite the admittedly confusing capitalization, not referring to a US state or a sovereign state but a general political organization that controls some land [1]. It's more than unnecessary to transition this into a remark on the mainstream US political parties.

> And really, arranged marriage as a "solution"? Really?

I'm not sure that gp would be the person to implement it, but if the problem is a literal read of the headline then arranged marriages are a reasonable solution. I might be about to learn some, but I'm not aware of any compelling argument that arranged marriage + liberal approach to divorce wouldn't work well vs the western-style dating system.

Something like half of marriages (major Anglosphere countries) end in divorce,and there are some extremely well grounded stereotypes suggesting that people under the age of 30 don't make great long-term decisions. Self-assessing your prospects as a young person is also difficult; there isn't a lot of life experience to fall back on.

In principle it is better for people to organise themselves personally. But if that isn't working out, then a more communal effort is a reasonable fallback. It probably wouldn't lead to worse outcomes.
So, taxes, then?

You can see where the problem is here. Sure, there's always work to be done. But who wants to pay for it? You said business doesn't want to. So it would have to come from the Treasury. I don't think you'd find wide support for taxation for those kind of projects.

The biggest challenge doesn't seem to lie in the actual video quality. The problem is in getting the damn call up in the first place, with all participants seeing and hearing all other participants.
You absolutely still need docs on the end point.

If you’re interacting with the api then it’s extremely likely you’re not going to write code that will automatically follow reference links and attempt to parse them dynamically.

You will need to know what fields are in the end point how they represent data (iso 8601 for dates? Unix timestamps?).

You’re substituting documentation with asking the api consumer to explore and discover and assume.

What part would be driver-owned? The elephant in the room here is that the economy of scale from a taxi company comes from owning and maintaining a fleet of cars at a lower cost than a single vehicle owner would pay.

If "cooperative" drivers own their own cars, that goes out the window. If they have to be business partners to be "cooperative," that opens a whole can of worms about whom you want to be in business with and how you would make company decisions.

The Uber model is nuts; I agree with you there. But, at the end of the day, there wasn't anything wrong with the 100 year old taxi model to begin with.
