Any gravitating body whose size is less than its Schwarzschild radius becomes a black hole. As the article remarks (can’t quote it exactly because I’m using a client that has an irksome modal interface) some of the ideas floated is that this black hole could be about fifteen centimeters across, and have the a mass of a very large planet.

Science fiction fodder notwithstanding, from a suitable distance this kind of body would behave exactly like any other gravitationally interacting body, and would perfectly obey the usual laws of motion (Einstein’s General Relativity if you’re insisting on investigating it up close or in minute detail, classical Newtonian dynamics if you’re observing on a broader scale). It has mass, it has inertia, and it would be interacting gravitationally as the textbook “product of masses, reciprocal of square of distance” law. It would be a big, dark, featureless bowling ball with the mass comparable to a gas giant.

So, what other types of physics is not well understood and requires funding to further research. We know F=ma, things in motion stay in motion, blah, and so on. We know a current flowing down a path will generate a magnetic field. We electrons moving to a lower energy path will release energy. We know light bends in a lens, and how to make that useful. Essentially, the funding for pure research and discovery is going to be more exciting than how to take a current understanding of physics into a way of making money. Plus, that kind of research should be undertaken by private investment.

> You should strike some balance between the impressing the employer and attempting to dig up the warts.

Very true. I feel like a few comments have said the same thing, but it's worth saying a few different ways.

I remember from "How To Win Friends and Influence People", the author describes how he simply asked someone a lot of questions at a party, and let them do all the talking. Later he heard that person thought he was an excellent "conversationalist", even though all he did is ask questions.

Don't be too adversarial in you questions. Simply asking some friendly questions that give the interviewer a chance to talk about their achievements and interests will cause them to like you more.
There were theoretical reasons to suspect that the Large Hadron Collider, by ramming particles together with sufficient force, could create microscopic black holes with approximately the mass of an atom. This turned out not to occur, but yes, at least in theory black holes can be very small indeed.
> conservation of momentum is the right way to think about that

So you’re saying you’d expect a body that were captured at an arbitrary angle to end up orbiting in the same ecliptic as the planets roughly around the sun’s equator?

This. It is all about the right balance. Here is a good analogy that makes sense to me.

Going full-on penny pinching in the first half of your life, hoping to enjoy it later, is going to rob you of a ton of experiences that you won’t be able to experience later in life.

On the other end of this spectrum, throwing money around and living just for today, without long-term plans and savings, will rob you of a ton of experiences in the second half of your life. Mind you, very different experiences than the ones you were missing out on in the penny-pinching scenario.

So it all boils down to a solution that sounds really simple, which is what makes it really difficult to act on and execute. You just gotta balance those two approaches in such a way, that your experiences are maximized across the board.

But saying that isn’t really solving the problem for anyone, as that’s akin to the famous joke tutorial on how to draw an owl. Saying “just gotta balance is right” is like saying “ Step 1: draw 3 circles. Step 2: draw the rest of the owl.”

So in the end, there is no real concrete solution. The best we can get is a solid guideline of “balance things in order to maximize your overall experiences”, but the actual answer to how to properly balance things is different for every individual and is left for self-discovery.

Procrastination can be caused by any number of things separate from a lack of discipline. It can be a subconscious signal that we doubt the importance of a task. It can be a signal that we unconsciously know we aren't prepared for a task. Maybe it's a strategy to wait until the last possible moment so we have the best possible information and maybe even find an alternative task that is better.

I don't believe "discipline" is a useful concept for everyone. We all have different brains and different circumstances. Some are motivated by discipline and duty, others by novelty and randomness. To an extent most of us can exert our will to build more of one side or the other, but it's much more efficient to exploit our supposed weaknesses at the same time as we build our strengths.

I feel like I've seen examples of the "discipline" crowd and let's call it the "gamification" crowd preaching their one true way, so it's clear that both seem to work for some people, and maybe we can all try to apply some of each to solving problems of motivation and procrastination. But speaking for myself, discipline is rarely the tool that works for me, and it's just that after some amount of waiting I suddenly feel ready to take on whatever it was I was delaying. I think that some kind of randomness might actually help if I can summon the discipline to do just one thing if I don't yet know what it is (I haven't read the article yet so I don't know if what they describe is similar to what I've been noodling on the back burner of ideas).
> How small can a black hole be and still qualify as a black hole?

There's no theoretical lower bound on the mass of a black hole. Once matter has ceased to repel other matter, it will continue to fall inward. A violent impact could generate the forces necessary on a small scale to create micro black holes. Black holes do seem to slowly lose energy though, so small ones would not live very long[0]:

It sounds interesting, but because it's not in English, I don't understand the details. Have you considered an English version of the Readme?
Awesome. If we can get FFI with Stan I'd like to connect DifferentialEquations.jl to it and poke at it with various problems to see how well it does on a few things. We can provide custom gradients if there's an interface for it, but I couldn't figure out how to do it without modifying the Stan source itself.
I've also had some bad encounters with the GCP docs, particularly around object storage. That was a while ago and may have been fixed. Early on they were not consistent with the actual APIs and poorly organized to boot. It was complicated by the fact that the APIs seem to have shifted.

Amazon overall has done an excellent job on documentation. It's made easier by the fact that they rarely change API behavior once it's deployed.
If you're making a general rule, I would refrain from using absolutisms like "never" which alienate the outliers like myself and invalidate your statement.

Concerns like this are perennial: https://news.ycombinator.com/item?id=926604. A couple years ago I gathered a bunch of links about the history of "HN getting more political": https://news.ycombinator.com/item?id=17014869.

That's not to say there isn't a decline, just that it's hard to discuss objectively. The dominant factor in such perceptions is randomness; more precisely, the streaks that occur in randomness that feel like they can't possibly be random. That explains why people have been saying the same things in identical language for so long. You could even make one of those guessing-game sites out of such comments. For example: 2010 or 2020?

The community is full of ideologues to the point where the comments are most often just predictable talking points being regurgitated ad nauseum. Everyone talks about the intelligent conversation, and it does happen, but far more times it’s just the same clichés repeated over and over.

(2010, of course, or the question wouldn't have made sense, but you see the point.) A decade is a lifetime in internet dog years, so HN already has survived these concerns long-term. If there is a downward trend, it's a slow one. Some of the things we've done to stave it off (https://hn.algolia.com/?dateRange=all&page=0&prefix=false&qu...) must have done something.

Can you expand on why you think this? I'm not a physicist, but I feel like one shouldn't discount the possibility of useful discoveries. I'd love to hear if there are reasons that's not true.
That depends on how much we slow it down; after a vaccine (in a year), we DO drastically change the number infected. Other countries (South Korea, NZ, Taiwan) have changed the number infected, and will probably end up with much fewer infected.

For now, we want to drastically change the outcomes; for example, a month ago, you would have been given chloroquine, which doesn’t help but has side effects; maybe in a month we would know about therapies that reduce mortality and long term effects by a significant percent (or maybe not :)

Tons of testing and contact tracing would probably let the US end up with fewer people infected.
I don’t have a best friend relationship with either of my parents so there’s not much to talk about that would genuinely interest both parties (in the topics alone). But I know my parents (especially my mom) are among the few people in the world who genuinely care about me no matter what, so we listen, and we share otherwise boring things like problems at work. It’s partially driven by a sense of obligation, but I think the human connection is worthwhile.

P.S. Talking about politics is a recipe for disaster. There’s always something to disagree on, and in an unrestrained environment like between me and my parents it could easily escalate. I hardly ever came out of such a conversation unscathed.
There is an entire section of "the organized mind" centering on decision making. I am reading many things here that are discussed and explained from a cognitive psychology viewpoint in the book. I can't recommend it enough.
The Eureka moment for me was similar, but slightly different. Consider a variant game with N doors. You pick a door, then Monty offers you two switch your payout to "the best single result from the remaining N-1 doors". Clearly, you would swap.

Now set N to 3, and consider that, by opening a door without the prize, that's exactly what Monty's offering you.
You are correct: a black hole whose Hawking temperature is less than that of the cosmic background radiation is “colder” than the space it is immersed in and consequently absorbs energy (and mass-energy equivalence) from the heat bath it is immersed in. The easiest way to envision it is that the black hole swallows up photons of the microwave background radiation and is emitting less energy as Hawking radiation, leading to a net imbalance in the black hole’s favour.

Of course eventually the expanding universe will drop the temperature of the cosmic background radiation further and the process will reverse.
Workers testing positive, leading to quarantining the whole staff to prevent further spread.

For the ones that are still active, the reduced capacity is a mixture of limiting the number of workers to maintain social distancing, and workers just not coming in for fear of getting infected.

Something else I didn't realize, from that link, what is being processed is now unbalanced - the same throughput feeds less people because restaurants aren't open:

> Restaurants typically use the expensive stuff — strips, ribs, tenderloins and sirloin, Bormann said, while retail takes the chucks and rounds and trims. With restaurants mostly shuttered, “all of a sudden 23 percent of the animal isn’t being bought because food service is gone,” he said.
There is another meaning, akin to "needle in the haystack". This is the only meaning I was aware of until I used the phrase to describe my then-girlfriend. She was only aware of the meaning you reference. It was awkward, but we're now married.

Over the years I have asked many other people about this phrase when it came up in conversation. Most of my acquaintances only knew of the "needle in a haystack" meaning. These people went to Berkeley, Stanford, etc. and worked at FAANG or are doctors/lawyers.

I have wondered if it's a geographic thing — most of these people have spent most of their lives in California. Perhaps the east coast is different?

I recently used Google Sheets as a CMS for a couple of projects.

In my case I had a server-side script which read the sheets, converted the data to JSON and saved it on a file which was then fetched by the JS client. The conversion only had to run when there were updates (e.g once a day).

It was really convenient in my particular case because all users where familiar with Google Sheets, already had users and passwords, and I had good granular control over permissions.

Ask HN: Does an enforced lockdown also imply a temporary end to the free market?
This is a genuine question.

Isn't a lockdown in a free market system inherently unfair? If some businesses are forced to shut down and many people are forced to stop working and therefore giving up their ability to provide for themselves, whilst others are allowed to continue their work then surely that is giving some priviledged elites an inherent and unfair advantage, not just during the lockdown but even for many months and years after, since everyone else will be in recovery mode/damage control for quite some time while whilst others will continue to "expand".

That makes me think that the only ethical way of enforcing a temporary lockdown would be to also transition to a temporary marxist system. Collect 100% of profits and incomes and evently distribute it across the population whilst the economy is being put on hold. I know that sounds crazy, but so does a lockdown right? If we enforce a lockdown then surely we should do it the right way?

Obviously if that was the case then I'm not sure if many people who are in favour of a lockdown today would be still in favour tomorrow, but everything else just feels wrong.

I know that on HN the majority of readers still work (from home), have above average incomes, and generally cushy lives in comparision to the general population, so it's easy from our point of view to strognly advocate for a long and extensive lockdown, but would you all be prepared to give up 100% of your wages and live in a communist society until the lockdown has been lifted? After all who cares about economy (including yours) when lives are at risk, right?

If you wouldn't be prepared to those measures, why not? Why would you not give up something yourself if it's clearly the right thing to do, but ask others to give up theirs?

Short version: it's workers getting infected, which shuts down the plant to stop further spread. The "market mechanism" can't avoid that.
My parents locked me in the garage. They beat me. One time my dad tried to bend my fingers backwards as torture.
No, I don't think so - we still do, _when the resources of security, nurses, EMTs and paramedics_ are exhausted, say someone in excited delirium. A smaller hospital like this one has far less of this "buffer" so their first step for any kind of potential restraint/sedation event in a behavioral setting quite likely will involve calling police, from their own liability perspective, in situations a larger hospital could likely handle more easily.

I am not advocating for this. I think LE has near zero role to play in these scenarios except for the _very limited_ "poses an imminent danger to self or others".

But in a town of three thousand people, I guarantee that when a behavioral crisis escalates at the local "hospital" (I couldn't even find how many beds it has, likely under 10), for better or worse, the police are being called.
The important differentiator for this black hole is that it would be a captured primordial black hole. It's basically impossible for such a black hole to form in all natural circumstances except the big bang.
The famous Douglas Adams quote is relevant: "Space is big. You just won't believe how vastly, hugely, mind-bogglingly big it is. I mean, you may think it's a long way down the road to the chemist's, but that's just peanuts to space."

The odds of an alien civilization picking up one of our probes, even if we send out thousands of them, is preposterously small. Imagine trying to such an object if it had been left floating at an unknown point in the ocean; now consider how much bigger interstellar space is than Earth's oceans.

It solves one problem, but creates another (the other side). If a truly bad bad payment was made (say, account hacked) there is no way to reverse it.

Great for the receiving end, but potentially troubling for the sender.
> I don't like the design of systemd

I feel like many who level this charge have unfortunately never really looked into its design or compared it realistically to what came before, because I can tell you that if I am comparing the ability to write a systemd service in a declarative way and having it working with the same set of commands across all major distros, I'll take that over having shoddy quality bash scripts that vary across distros just slightly enough to annoy and that rely on a patchwork of PID files that is very easy to mess up, I am taking systemd any day of the week.

I’m up voting because I want to hear this side of the argument. I guess your point is that most people’s experience isn’t that bad, and they owe their parents.

Sure, so it can just be a matter of balancing how they treat you and your family vs basic decency and the benefit of merely maintaining contact and having them around as grandparents for your kids. Everyone’s experience and tolerance is different.

I don’t think we necessarily owe our parents. They made the conscious decision to have us and raise us, that ought to be a reward in it self.

I certainly will the best I can for my kids, but I don’t want them to think they owe me anything. This is especially true if I am (unknowingly or unconsciously) treating them or their family very badly.
