I'm not sure where I've seen this described, but apparently a single black hole already reflects light back toward the observer, through a series of concentric rings, where each inner ring reflects light that has gone one more time around the black hole

Edit: https://www.quantamagazine.org/black-holes-ring-of-light-cou...

> Photons that make a single U-turn around a black hole and then zip toward Earth would appear to us as a single ring of light. Photons that make two U-turns around the hole appear as a fainter, thinner subring within the first ring. And photons that make three U-turns appear as a subring within that subring, and so on, creating nested rings, each fainter and thinner than the last.

> Light from the inner subrings has made more orbits and was therefore captured before the light from outer subrings, resulting in a series of time-delayed snapshots of the surrounding universe. “Together, the set of subrings are akin to the frames of a movie, capturing the history of the visible universe as seen from the black hole,”
> Shady.

> Willing to be paid in strange currencies deposited in overseas banks.

I'd need a more concrete definition for 'strange currencies', but discriminatory behaviour shouldn't be applied to anyone that has an account overseas, especially in the age of global banking & cross-border payments.

> Likely to have tax troubles one day.

On the one hand, this will definitely happen: Internationally-acquired income often subsequently leads to poor tax handling, especially if the individual involved is unfamiliar with the intricacies of filing taxes for such sources of income.

However, it is also a consequence of overlapping jurisdictions & law enforcement, with unified, clear & unambiguous definitions being the exception rather than the norm.

> Knows how to buy a plane ticket using cash.

Why is using cash a problematic behaviour now? Just because I still use cash doesn't mean that I should be classified as 'shady'.

> Strong opinions on Krugerrand valuation.

Tried to search this & only found references to the gold coin with the same name. As similarly stated beforehand, why is being a goldbug now 'shady'?

> Owns a motorcycle without an odometer.

...I can see why: An odometer, coupled with the motorcycle's purchase histories, is a good way of finding out the roads that a person used to travel on with some reliability.

> Bought a house with a series of 9,999$ travelers checks.

Same as the plane ticket: The large denomination will raise eyebrows, but it shouldn't be used as a marker for discrimination.

> More likely to install a Kim Dotcom-type panic room than run for public office.

...This is similar to the odometer-less motorcycle: The individual wanting to install a panic room is likely someone that's thinking about worst case scenarios, & planning with that in mind.

------

All of the listed "shady" traits stem from a core: Paranoia, specifically paranoia of a malicious State. More generally, it's the fear that the State will use the information it gathered about a person for unwarranted surveillance & eventually prosecution over the slightest infractions.

In earnest: Why is paranoia suddenly a "shady" thing?

If you're just starting off with JS or TS you shouldn't be messing with tooling at all. Just install one of the many create-react-app derivatives, run one command and start developing. All those boilerplate generators support TypeScript now, too, so you don't even need to do anything extra to start using TypeScript. Even TypeScript itself can be incrementally adopted since it's a superset of JS.

You will outgrow those app generators, but for a learning project? There is no need for you to even see a webpack file.

Speak for yourself. While it might be harder these days, the people I've seen that followed Walter's plan above were all able to get good jobs and support their families, including people who, like the sibling says, are poor, had to take care of siblings, had overworked parents, and so on. Yes, systemic inequalities exist, but well, an individual can't do much by themselves if they use that as the yoke on which they exist, they are not going to solve their problems or their family's poverty within a few years via voting or protesting, more immediate solutions exist. One must not fall into the trap of learned helplessness, and at some point, one has to cast off the yoke of bondage and begin to solve one's problems.
I just finished a migration like that, and after some research ended up writing shell code to implement 3 methods and put them to the test. Maybe it is useful for you so I'll leave it here:

My first step was to learn the procedure that devs behind GStreamer used recently, when they went ahead and decided to merge all their disparate repos into a single monorepo. For my needs it is the less adequate of the three because it will break as soon as there is any collision between the desired destination and the already existing files of a repo.

The second method is one proposed in the JDriven blog. It doesn't suffer collisions because the movement into destination subdir of each repo is done separately on the original repos, and then they are merged with everything already in place.

Lastly, I found a third method which is the one I liked the most. It uses git subtrees, to perform the move and merge all in the target repo (the monorepo itself), without touching the original repos (unlike the JDriven proposal), so everything is tidy and left in place.

Belief does not count as scientific process...Maybe start at the study findings

"...Using a system called “ICE” (inducible changes to the epigenome), we find that the act of faithful DNA repair advances aging at physiological, cognitive, and molecular levels, including erosion of the epigenetic landscape, cellular exdifferentiation, senescence, and advancement of the DNA methylation clock, which can be reversed by OSK-mediated rejuvenation. These data are consistent with the information theory of aging, which states that a loss of epigenetic information is a reversible cause of aging..."

What are the poor people supposed to live off of? Potatoes, beans, and rice 24/7?

That diet is a tough sell. Especially since people in a low socioeconomic position are frequently quite busy trying to hold life together between 2-4 jobs and a family which includes children. I can understand why someone in this position would spring for something quick, easy, flavorful, and requiring as little expenditure of mental and emotional energy as possible.

The lack of empathy demonstrated throughout this thread for less well-off folks is not surprising but still a disappointing non-deviation from the HN stereotype. Why is it so hard to imagine being in someone else's shitty position? Being poor obviously sucks, it wears people down and disrupts and interferes with making optimal long-term decisions. This is obvious and I can't say I've ever truly been in this exact situation.

Having seriously contemplated getting one of these roofs, the real problem was working with Tesla. Fine, Tesla sells cars with essentially no customer service. It’s a thing you order off a menu, and they make it and deliver it.

But a roof is fundamentally a custom installation. You need flashings. You need it to integrate with gutters. You need to make sure the thing is compatible with the roof slope. You may need penetrations. You need to have drawings and specs for the contractor and the structural engineer. You probably need a (correct!) permit drawing. Someone needs to answer the phone when the GC calls. And you need the thing installed, on time, competently, so the building can have a roof when it needs it.

Tesla is terrible at this. Any of a large number of roofers who sell products from various large and small roofing vendors can pull it off — it’s not hard, it’s not rocket science, but it requires an actual human who has volition. Maybe AI or really amazing construction software will do this some day, but not yet.
If your entire codebase uses static typing, you don't even need an entire class of unit tests for checking the validity of inputs/outputs to functions. You can spend that time testing business logic instead.

I think I get the gist of your point which I would handwavily summarize as “there is no there there,” which I agree with. But I’m thinking that in terms of functionality, there is no real distinction here. Like If I train a model to do video game physics, and reward it for getting the tank shell missile to land on arbitrary targets, then in some sense the system must have an abstraction of gravity or at least parabolic movement or at least a functional equivalent of that, and it must be able to “hypothesize” about the consequences of its model because that’s what it needs to do in order to hit the target, ie, “everything I’ve seen before leads me to believe tank missiles move like so, therefore if I apply the following forces, it should hit the goal”—the degree to which it wins at this task is exactly the degree to which it can form working models of its environment and reason about the cause and effect of the actions it can take. But of course all those words in the previous sentence are wrong because it’s not exactly doing any of that, just something functionally equivalent and automatic.

Maybe we disagree about whether that last point means it can meaningfully “do abstraction” or not.
A lot of academic/scientific belief is based on ignorance. Hear me out.

The entire academic/medical establishment believed the appendix was "just a vestigial organ" which served no purpose. It was taught in every university, in every textbook. Every medical professional knew it was a fact. Why? Because they had not identified a purpose. In their ignorance, they adopted the position "I don't know what it does, therefore I can state as a fact that it does nothing." Except it turned out they were all wrong, for a very long time.

The appendix is not the only example of that mentality.

The same has occurred when it comes to estimates of the age of the universe.

When the most powerful telescope could see N lightyears, people believed the universe was N years old. Tiny gains or new images using that telescope adjusted the estimate to N.fraction years.

When the most powerful telescope could see 2N lightyears, people believed the universe was 2N years old. Tiny gains or new images using that telescope adjusted the estimate to 2N.fraction years.

When the most powerful telescope could see 3N lightyears, people believed the universe was 3N years old. Tiny gains or new images using that telescope adjusted the estimate to 3N.fraction years.

This happens every time. Yet astronomers and cosmologists refuse to learn the lesson, and keep repeating the same mistake.
In China, the authorities would immediately send the police to arrest the entire corporate suite. They have even executed corrupt CEOs, for example in the tainted milk scandal.

In the United States, nothing will happen. No law was broken, you would say. Still. There should be consequences. There should have been consequences. In China, prosecutors would chalk it up to general charges of "corruption" or "public dishonesty" or whatever.

In my experience you must write more tooling to get the monorepo to behave as you'd expect, and being able to use off-the-shell tools for CI/CD and orchestration is a huge win vs. having to convince those tools that deploying both the periodic service workers as well as an HTTP backend is actually Totally Normal when it's not.
> It also has to be coordinated across the entire organism somehow so that all tissues and organs age at the same rate, like they do in reality

How could you possibly justify this claim?
I took a grad school processor design course. There was an equation for calculating the approximate power draw of a processor, and there was a f^4 or something in there, f being frequency. The 6 GHz clock speed has a lot to do with the power consumption.
The only thing that matters for climate change is the amount of gas burned - the efficiency with which we turn it into work is irrelevant. If we reduce the amount of gas burned, at a cost of burning the remaining gas less efficiently, that's still a win.

In a certain sense one should expect lowering usage to inevitably lower efficiency, as a sort of inverse corollary to Jevon's paradox (which states that as efficiency rises, total usage does too).
It's hard to look at even $25k for a solar roof when I see panels on sunelec.com going for ~ .33/watt, sometimes less.
Seamless for us would mean roughly twice as much power output - the gables on our roof are inconveniently sized for standard panels. Combine that with the cost of a new roof and I’d consider it at a modest markup, but they’d have to convince me it has better than Tesla build quality.

Availability to millions is irrelevant unless millions want the product. Otherwise it becomes unsold inventory, a liability. Cook knew that as well as anyone.

Jobs was a notorious micromanager. Not to mention that at the very beginning, it was just him and Woz. I'd like to see Cook start a tech company from scratch. Jobs did it twice.

Um, Apple didn't have a yearly schedule until Cook.

the tunnels i went through in japan were all at least 2 lanes in each direction. there were plenty of cars and traffic in the cities i visited so it can't be that inconvenient.

it would be roughly $600B to build enough neighborhood parking garages in LA to serve all its residents. that's just half a year's worth of GDP, which is not nothing, but certainly within reach. with just that, LA could remove all on-street parking in neighborhoods and turn it into bike lanes and/or extend the curbs to add more trees and sidewalk.

Luma is at full resolution, chroma is "upscaled", but we're less sensitive to color than to light so it's almost as good.

Most JPEG uses subsampling on chroma channels anyway.
It does... but I'm guessing those rings of navelgazing, as it were, would be infinitesimally thin. Further out, there is less distortion and perhaps a hope of figuring out what one is looking at.

Edit: a ring??? Mind blown. I guess it makes sense, the light doesn't have a preferred direction to travel around the hole... still, that's wild. It's like how photoreflectors throw light back where they came, but instead of internal reflections of a sphere... yup, mind blown
They also would not allow people like Jane Fonda to drive public opinion on critical infrastructure policy like Nuclear Power.
To much economics too little philosophy. Hunter gatherer societies didn't operate like that. Families don't operated like that. The reality you describe was a deliberately constructed, self-absorbed culture that is by no more a natural state of being than a theocracy, comnune, or fascist dictatorship. Read Kant.
What is inhumane about it? I've read your other comments too, it doesn't really seem like you're arguing in good faith when you state superlatives like "this is the most inhumane thing I've read today" or "this is the worst take I've seen in forever on this topic" or "I am going to be incredibly rude now." Please make your points without resorting to such extreme language.
Calling mental models "laws of physics" is the biggest linguistic disservice to science itself, so in a way, yes.

The second half of your comment still complains about the WA DMV, despite the first part of your comment trying to whitewash the general problem as "Gathering data users are willing to give you isn't a crime by any definition". This reads to me as cognitive dissonance. Even though users hand over some data "willingly" for some purposes, they do not seem to be happy about this state of affairs, nor have they condoned every purpose it is ultimately abused for. This is demonstrated by the evergreen interest in news articles about how company X is abusing customers' data - if people didn't care, then they wouldn't be popular.

You're trying to shoehorn this concern into whether or not it is a CFAA violation, which it is generally not. But privacy is orthogonal to unauthorized access - a healthcare provider can violate HIPAA even though they obtained your data legally. A comprehensive privacy law ala the EU's GDPR is the first legal step for pushing back against the massive abuse of data all of these companies shamelessly engage in.

And it is unfortunate that with the brokenness of our political system there would be many loopholes carved out of such a thing (like your DMV example, the longstanding financial surveillance bureaus, etc). But only by starting to draw a line in the sand can we possibly move towards a society with a meaningful concept of privacy, and repudiate the unaccountable totalitarian systems that Surveillance Valley has been building.

I agree that this particular ban seems like nothing but simplistic political grandstanding. But once again there is a much simpler universal rule that should already have been in place for state owned devices - a blanket prohibition of every app that isn't necessary for the job.
