From the site's "About" section:

I know what to do this weekend if it rains!

One sentence I heard somewhere wraps up the totality of computing:

"If Mathematics is the 'what', Computer Science is the 'how'".

This applies to each and everything.

> 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 spoke in the context of supercomputer clusters, and usage in scientific HPC.
__rito__
·4 дня назад·discuss
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.

My country only recently switched to 4-year undergrad for all streams. Previously, only Engineering had it (not counting professional degrees like Medicine, Accountancy, etc.)

GaTech only permits OMSCS if you have a 4 year undergrad. In many countries undergrads are three years. Even you have a Master's, that is also not counted. 4 years undergrad or nothing.

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.

This is a great book if you already know good amount of Math. It helps you fit things into a bigger picture. Really appreciate the fact that something like this exists.

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.

Dostoevsky is surprisingly great to read. I first started with "Notes from Underground (1864)" and I found it a profound book. Then I read Brothers Karamazov, and it is one of those "great" books. I wrote my reflections here: https://ritogh.substack.com/p/reflections-on-brothers-karama....

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.

Coming from him, I am not sure even that is real. It could very easily (and plausibly) be a part of the ongoing hype drama.

"Our models so precious, US Gov has to revoke access to foreigner." - tuned up version: "Our models so advanced our #1 adversary is desperately stealing it from us."

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?

Is Wero something you can hold in your hands?

RuPay is just like Visa/Mastercard in the sense you get physical cards that you can use at ATMs, use at ecomm sites, etc.

Wero doesn’t seem to be that. Am I missing something? Does making a new direct alternative to Visa/MC doesn’t make sense for the EU? If so, why?
