That is true. But you can rise above it, or choose to ignore it. If not, then it is not the right group.

I have been part of groups with vile internal power struggles, politics. I never ever took part. Was okay. Maybe there is a threshold somewhere that I have not found yet.

4. Be part of bigger things

Being part of bigger things makes us feel valued. Find communities and projects to be part of. Start your own. It could be online or in the real world.

Make sure the groups don't get politically active one way or the other. Today's social landscape is made significantly worse by political polarization dragged to the extreme - fuelled by short form content silos and bubbles. (Tiktok, Instagram, etc.)

Ban politics strictly in the spaces you create, and don't be part of the ones that lean one way or the other - unless you are actively looking to take part in politics.

This was not the case even ten years ago. But now, is.

What you are saying is true. But YouTube/FB algorithms are deliberately skewed towards regular posters.

It's like your content of love that you produce once or twice a month won't be shown to the users at all.

Where do I get the time after job, family, friends and self-study?

So I don't create content like that at all. I write. And that's all.

But I also want to make videos. The recording, editing timeline is way too high. And then if your stuff is not shown to anybody, that's a huge bummer.

Don't tell that to Indians! A lot of humans are named "Santosh". :x

Unlike in the West, naming one's dog after someone's name is considered an insult. "I will have a pet dog named after you" is insult thrown in fights. So, Indians name their dogs uncommon among humans. Or they have foreign names like Johnny, Jack, etc.

From the site's "About" section:

"Ergo is a nonprofit that publishes long-form philosophical lecture courses with leading scholars. Everything we publish is freely available, without ads or paywalls."

I know what to do this weekend if it rains!

Scheme Is a Hoot 15 days ago

Lately I've been spending time learning Scheme and using it to implement the concepts I'm learning in my physics classes as time permits.

There is a whole book for that: Learn Physics with Functional Programming A Hands-on Guide to Exploring Physics with Haskell by Scott N. Walck, December 2022, 648 pp. ISBN-13: 9781718501669

There is also SICM [0].

I was in Gray Scott School for HPC last week, and even in scientific usage, CPU-only cases, AMD is still a pain point. Many tools and libraries don't have first class AMD support or any support at all.

It loses to Intel in CPU, and NVIDIA in GPU, in case of scientific libraries and HPC-worthy libs, tools.

I think people who want an "AI Dev Kit" will lean towards Intel + NVIDIA setup.

I am not a fan of Intel, but their MKL, MPI, etc. are not paralleled. Same goes for CUDA with NVIDIA.

If this is not bad faith argument, then I don't what is. When someone is violating an OSS licence, they are doing it for commercial gains and monetary profit. Nobody is angry at someone using FOSS software for himself with no money getting involved.

As opposed to that, books, movies are pirated for personal consumption. Not monetary gains. If someone bought a $30 book, and then ran a BaaS with millions of VC money in his pocket, people in HN would be angry at him, too.

Agree with that. But I also meant full-names.

With so many Williams, Johns, Franks, Bens, etc. reading a novel with exotic names is just breath of fresh air.

Also feel the same when watching non-English modern TV/web series. Like Nordic or Spanish stuff.

Actually USSR pushed a lot of soft power and spent real money behind it. Especially the authors whose narratives didn't directly violate the narrative of the Party.

Leftist parts of society looked up to USSR a lot, and a lot of humanities professors, teachers all over the world were left-leaning, and promoted these books as Russian culture.

This is one factor, and doesn't explain the whole thing, of course.

See: https://news.ycombinator.com/item?id=48673777. Neither our family nor I ever leaned towards the Party or any form of Leftism, but books are always kosher in our culture.

Russian stuff were translated into Bengali a lot in 1970s - especially works favoured in the USSR. I came across multiple translations of children's books, and loved reading them as a kid. My father and aunt read those in their childhood. Raduga and Mir published Bengali books and printed them in Moscow, and shipped them to Calcutta. They were cheap, too.

I didn't like the flow of translation of Bengali versions of "adult" books, and read them in English.

My favourite Russian writer has to be Bulgakov who fell from grace of the Party, and his work was not translated. I am yet to read Solzhenitsyn.

Nowadays, there are indie blogs that scan and preserve those Bengali books. A lot of people I know download and print those books. You can still find Moscow-printed Bengali books in used-book stores of book fairs.

The main difficulty is the names. The names make it so hard.

I think that's an exciting part. When I am bored with names of similar kind, the names make the characters somewhat exotic. I don't know about you, but the name "Grushenka" adds to everything that is going on with that woman.

The most overhyped literature ever

Just because you aren't ready for it doesn't mean it's bad literature. That's basic.

I really like Dostoevsky. He was really onto something. What he wrote was deep and meaningful and profound.

Tolstoy is also great. His short story "The Three Hermits" (1885) profoundly impacted how I look into these things.

Okay, thanks. I get it.

ATM cards are still safer than mobile based payments.

Elderly fraud in the US, scam/fraud calls and digital arrests in India are made possible by social engineering attacks and duping people.

For ATMs, if one has online transactions turned off (default option when you get a new card in India for most if not all cards), it is impossible. One has to walk to an ATM in a crowded place, insert the card, enter a PIN, and can only then withdraw money.

Millions in India use debit cards this way.

In many countries, at least some banks are nationalized. India’s biggest bank SBI (State Bank of India) is a PSU (Public Sector Undertaking).

UPI still connects with bank accounts.

My question was about something else: why EU doesn’t try and develop a homegrown card provider? It would provide exactly what MC/Visa does. Are we beyond that point in terms of technological advancement? Some other reason?

Wero isn’t a physical card if I am getting this right.

RuPay is.

You get a physical cc/dc with RuPay as provider instead of MC/Visa.

If I am not missing something, Wero is not that.

That is what I wanted to know: why not a traditional, homegrown card that is a direct 1-to-1 alternative of MC/Visa cards? Does that not make sense for the EU now? Why?

Can someone tell me why the EU doesn’t develop something like RuPay?

Indian UPI gets mentioned a lot, but when Visa, Mastercard didn't agree with data sovereignty rules among other rules, India quickly developed RuPay [0]. Now most debit cards in India are RuPay. CCs stand at 18% share.

They also integrate seamlessly to UPI.

Why doesn’t the EU consider something like that? They want to jump direct to digital currencies? Is that it? Something else?

[0]: Data rules came in 2017/18, RuPay was developed in 2012 iirc. But it got unprecedented push after the rule.

I use a QR code based app locking mechanism that blocks browsers and some apps. I never turn it back on. That's all. I use a regular smartphone.

I heard this quote in many American movies: "The first way to get rid of addiction is admitting to yourself that you have no power over the substance." or something in the same vain.

I admit I am powerless over doomscrolling. I just create a barrier to entry that never expires. Solves my problems. No alpha male self control BS. Just brain chemistry-aware tricks.

If I were involuntarily injected with serious drugs, my brain would crave it. Social media is the same. No point arguing otherwise.

Something should be noted: equality didn't save them. They grew more equal, maybe. But that couldn't save them from barbaric hordes/drought/a combination of these or more.

They became extinct.

To an "educated", emotional mind guarded in a safe place, economic prosperity, the tenets of equality might show promise, but, they might ultimately be sans utility when seen from the lens of survival, thriving, etc.
