According to Wikipedia [1] we consume 9717 Mtoe or equivalently 408 TJ (per year, although it is not explictely stated, which I find annoying).

The earth moment of inertia is about I=8e37 kg m2 [2]

The energy extracted by a slowdown of angular speed from wa to wb would be 1/2 I(wa2-wb2).

Approx wa=2pi/86400 and wb=2pi/86401. Energy extracted: 4.9e24J=4.9e12TJ.

We would have energy for about 12 billion years.

If I double check with Kagi's assistant with Claude 3.7 (I'm in my phone and I could easily have made an error) it starts with my exact reasoning and figures but messes up final numbers (so close!!!) to give a total of 40 billion years, which nevertheless is the correct order of magnitude.

What does leftist mean in this context? Sure you could say the "nationalist" movements against monarchies and for more democratic processes were progressive at the time, i.e. they wanted to change the status quo. Calling them leftist in the modern sense (again with a huge caveat about what leftist even mean), doesn't make much sense IMO. Also it's important not to forget that the internationalist movements (which I'd argue fit modern definitions of "left" much more closely) developed quite quickly (in historical timeframes) after, e.g. it was only 50 odd years between the Warburg festival in Germany (generally considered the birth of German nationalism) and the Paris commune.
You have to admit, the track record for international intervention is extremely spotty. When was the last time that a rich country went into a poor country, for non-self-serving motivations, and fixed most big issues? I freely admit that I'm not a good student of history, but I can't actually think of one.
> And that labor will definitely not be available in 20 years at the level it is today. Pensions being public or private simply change the method of failure: currency devaluation, raising costs or bankruptcy of the pension system, take your pick. It does not change whether they fail.

Indeed but a government at least has some sort of accountability and long term thinking built in. The forces of the market are by nature short-term dominated and are accountable to effectively no one (but a few select billionaires).

This isn’t immigration. He’s a tenured professor and already has permanent residency at the very least. He is most likely a US citizen.

FBI is most likely dealing with an espionage angle. His research field of cryptography and using it to protect genomic data probably has something to do with it.

The US govt track record on stuff like this is quite abysmal with several researchers having their career and livelihood destroyed.

What he did was public domain, unless he consulted for alphabet agencies. The Chinese govt also has a pretty nasty track record of pressuring erstwhile Chinese citizens to engage in espionage by making life hard for family back in china
You're not wrong. Another part of the problem is that industry itself is rampantly anti-intellectual in many ways. I can't tell you how much of an uphill battle it can be to get coworkers to even acknowledge a useful idea from academia or read papers, even at good companies.

Hell, the "industry languages" are just now more broadly adopting good language design ideas that have been around in academic contexts for decades.

I'm not sure how to do it, but we really need a return to a society in which intellectual curiosity and sophisticated debate are viewed as worthwhile—our incessant desire to just maximize profit as quickly as possible over anything else and the sharp division between "the intellectual domain" of academy and "the real world" of industry needs to blur and evaporate.
The problem with migrating off COBOL is not COBOL. It is the fact that the business processes are not documented, and that they have been allowed to accrete special cases for decades. A very little of that results in unmaintainability very quickly, in any language. If the only way to deduce your processes is by reverse-engineering source code, in any language, you're fccked.
Nobody is preventing the citizens from digging their own well and ensuring their own water supply and having bad teeth.

I like it how when it comes to fluoride in water, that's the nanny state pushing things on people, but when it comes to municipal water, said people can't bother to use their freedom and get their own water supply. It's the same that parents refuse to vaccinate their children for measles and then hurry to the doctors when the child inevitably gets sick. The freedom to die of preventable diseases is a great thing!

Organic Maps is great and I'm hoping the transition to Forgejo goes smoothly for the project.

I've recently started hiking and just generally going outside in my community more. When I relied on Google Maps I would get some random business highlighted when navigating around. Since I switched to Organic Maps I see trails, artwork, parks, scenic views, etc, etc that I never knew existed even in my own neighborhood. I also love the idea that if I find something not right on it I can just open up Open Street Map, make a simple edit, and improve the life of everyone else using the app that comes after me.
There's an enormous semantic distinction between "Wang vanished" and "Wang was vanished".

Yes, as far as we know he vanished, but as far as we know he did so under his own will before the university even put him on leave.

> Exam question: Describe the attitude of Dostoevsky’s Underground Man towards acting in one’s own self-interest, and how this is connected to his concerns about free will. Are his views self-contradictory?

I don't know nothing about Dostoevsky. Never read any of his books. I don't even know when he was born or dies. I only know the word Dostoevsky. It can be any author or book, not specific to Dostoevsky. Now, coming to my hatred for the exam question: What the fuck am I? A telepath? How am I supposed to know what was happening in Dostoevsky mind when he wrote that paragraph in the book? Whatever is the answer the professor think is right, is that answer approved by Dostoevsky himself? If not, who the fuck the professor think he is to tell me my answer is wrong (yeah I know he can do whatever he wants with his exams - but you get the point) and not in accordance with Dostoevsky intentions? If Dostoevsky didn't write anything about his intentions of that book, what is the point of writing a book? Aren't words, sentences and paragraphs meant to transmit knowledge without so much delusional interpretations? This is all just mental gymnastic spouting one non sense after other without any way to confirm the real intention behind the author mental model.

I really don't understand this type of questions. Is there a book explaining the mental model of the author while he wrote the book under study? If not, any interpretable opinion is valid as any other.
What to Do- besides the help others and care of the world, plan for your future retirement, most don't. Seek education by reading as much as you can. Stay interested in your family. Desperately seek out beauty. Cultivate your sense of humor, even if it's a little snarky. Be who you want to be, as long as it won't hurt anyone, including yourself. (I'm afraid too many of us are afraid to stand out today, group mentality, on the whole, is toxic and can lead to "us vs them" stupidity.)

What not to do (just as important)- Suck. Be nosy, passive aggressive, judgmental or hateful. Allow yourself to be duped because you're to lazy to seek out information.
> Waste is still the giant elephant in the room and a lot of people have a fifth grade solution to the problem (we will bury it under ground! We will fly it to the sun! We will resuse it until it is no longer radioactive!)

The correct solution: put it into dry casks and do nothing right now. Store it simple underground storage facilities or on the grounds of active nuclear power plants.

The casks are fine for the next 300 years, and during that time we can either:

1. Perfect the nuclear fusion, it will provide plenty of neutrons to transmute the waste.

2. Perfect fast fission reactors. See above.

3. Use some of the excess of too-cheap-to-meter green energy for accelerator-driven subcritical fission reactors.

4. Yep, use rockets to slowly launch the waste into space. We can already design a storage capsule that can survive re-entry.

In any case, we have literally hundreds of years to come up with a solution and there are many viable paths.
Why do we have to be constrained by economics unlike the navy? The state within the state has access to nuclear powered ships so it is just a question of widening that capability to the members of the state living outside the walls of the keep. Not a matter of establishing precedent or anything. That part is done and long proven. The federal government even has experience managing water and power for entire geographical regions today.
ActivityPub just hands out "private" posts and trusts the foreign server implicitly to only show them to the right users.

(For what it's worth, at the time I wrote the comment, the rest of the comments on this story were about ICE raids).

Nobody knows anything about this story. He might be in custody, he might be in Indiana, he might be abroad, he might be about to get charged, he might not be, he might keep his positions at IU, he might have lost all his positions at IU.

It's an interesting story worth paying attention to because he's a prominent figure in an area of research we all pay attention to. But given some kind of criminal investigation is in process, and that he has a lawyer, there's no signal to derive from the fact that we can't get quotes from him in the media; that could just be him being smart.

One thing that's changed in the past decade is that college professors are now competing against youtube. There are really bad lecturers in college (and also really good ones!). But now, when you encounter a bad one, that's okay--you can watch lectures online.

What evidence do you have that they US government disappeared him? It's just as likely that he is an escaped spy and the university wants nothing to do with him.
What problem with the waste? Reactors are working and generating power today for many thousands of americans. Whatever is being done with waste today seems to work well enough to continue reactor operations without any major headlines. Just seems to be a bit of cognitive dissonance here between what is claimed online and what we see today out in the field generating power.

> Be here. Be present.

Most especially be aware of others' happiness or misery, along with our own heart's intentions and actions and how they affect both others and ourselves. Our sense of inner peace is dependent on how our karma radiates back into our heart from how we have affected others. This is the most sublime rule of the universe: you reap what you sow, for good or ill.

Cultivate universal compassion and then shine its beneficient light on as many people as you can with real effortful service.

That is the purest heading for our moral compass, and it's always our choice both what we choose to do and how to course correct our ideals, attitudes, and behaviors.

We ALL need to self-reflect and -evolve for the majority of our life, slogging through mistake after failure after falling short of the mark, learning humility and perseverance and mercy for others who need even more grace than we do.

> Like, I don't know when to implement the Monad type-class to my domain data types

A concrete type (such as your Tweet type) can't be a Monad. Monad is implemented on generic types (think: `MyType a`, where `a` can be filled in with a concrete type to produce e.g. `MyType Int` or `MyType String`).

Most monads are data structures like list `[a]` or structures which provide context to computations like `State s a` or `Reader r a`
Norway is like that.

Almost everywhere along the coast.

Just breathtaking.
Right. So you're either going to make a stand and risk getting arrested (Just like Thoreau!) or you're going to move somewhere this isn't happening.

Keep in mind we're talking about people with a moral framework that reduces the situation to these two choices. They'd need to abandon their sense of morality to maintain the status quo.
> FBI + Client Attorney present + University's data scrub + nothing on the public docket likely means FISA court

No, it doesn't. Foreign Intelligence Surveillance Court proceedings are only warrant applications for surveillance that cannot be used on criminal trials; targets wouldn't be informed of or represented in proceedings.

Espionage or terrorism charges are handled by normal US District Courts, on the public docket (though certain documents and proceedings within those—or any other—cases dealing with classified evidence are handled under special procedures to preserve the secrecy of the evidence )

Fun fact, the "correct" term is the one in use. Dictionaries define language after the fact, they do not prescribe its usage in the future.
We have no evidence that Wang "was" disappeared. We know that he's nowhere to be found, that the university put him on leave weeks ago [0], and that the FBI recently searched his home. Notably, the university put him on leave weeks before the FBI searched his home.

That sequence is better explained by the hypothesis that Wang vanished himself suddenly and the university called in the FBI to investigate things that they found in the aftermath. (Note that that's still pure speculation, but it's speculation that better accounts for all known facts.)

12 year old asking her friend can have a social media account but she can't. TV, food habits, bedtime, etc. Not our problem. Also applies to cleaning up what's around you. The alternative is paralysis and not cleaning up anything.

(No implied critique of the actual essay) but when I saw that title from PG, I was really hoping it would address the 2025 question "What should one do now?"

At a time when it seems like so many pursuits or activities or things to make are overshadowed by " but won't there be a model in the next 6 months that can just do this itself?", not to mention all the other present world uncertainties...

Well, it would be nice to hear more thought as to how to focus one's energies.

(I have my own thoughts on this of course, but what I'm really advocating / hoping for is more strong takes on the question.)
Nobody wants to hear it, but I don't think it's right to call it naivete. The source article says that local media were able to reach a lawyer representing the family, who did say they're not sure what the investigation is about but didn't say anything like "my clients are missing and I don't know where they've been taken". If the FBI hasn't filed formal charges yet, and the targets of the investigation aren't interested in talking to the public or the media, the only options are to wait for more information or engage in wild speculation.
The unprofessional and arbitrary nature of the administration I fear empowers lower levels of government officials to behave similarly and that leads to absurdity … and corruption.

Ask HN: How to improve academics after drop out?
Hi Everyone,

I'm just 19 years old, from Tbilisi, and I'm looking for ways to improve my academics.

I graduated high school but never went to university. (Yeah, I'm not a dropout; it was clickbait)

I've been working full-time on startups and various companies since I was 14, and my CV has become very cool. Now, I'm a growth engineer. living on my own from this age.

When I didn't go to University, I was thinking like - It's okay, I don't want it. " I still feel this way, but I want to enhance my personality. I want to learn more about the world and improve in different fields, not just software engineering.

So... I'm looking for a way to do that.

My question is, where should I apply? Since I'm in Tbilisi, remote opportunities can be a priority, but I'm open to relocating. Are there any scholarships available?

Thanks, I appreciate the strength of the community.
Reddit and HN can be very addictive, and Instagram and YouTube and TikTok with mere “highest upvote” per topic would still be. I’m doubtful that your strategy would do very much about the problem.
