È divertentissimo leggere E.T. Jaynes, in particolare i suoi ultimi lavori. Questo passaggio è da "The Gibbs Paradox". Si può scaricare qui.
There is a school of thought which militantly rejects all attempts to point out the close relation between entropy and information, claiming that such considerations have nothing to do with energy; or even that they would make entropy subjective and it could therefore have nothing to do with experimental facts at all. We would observe, however, that the number of fish that you can catch is an objective experimental fact; yet it depends on how much subjective information you have about the behavior of fish.
Traduzione in italiano:
Esiste una corrente di pensiero che respinge con forza ogni tentativo di evidenziare la stretta relazione tra entropia e informazione, sostenendo che tali considerazioni non abbiano nulla a che fare con l’energia; o persino che renderebbero l’entropia soggettiva, e che quindi non potrebbe avere alcun legame con i fatti sperimentali. Osserviamo, tuttavia, che il numero di pesci che si possono catturare è un fatto sperimentale oggettivo; eppure dipende da quanta informazione soggettiva si possiede sul comportamento dei pesci.

I'm working on a new JavaScript/TypeScript library for natural language translation powered by LLMs. I want a name that feels elegant, memorable, and reflects the essence of translation.
I've narrowed it down to four candidates from different linguistic roots. Which one do you think fits bets?
Xindaya (信達雅): Derived from Yan Fu (嚴復)'s Three Pillars of Translation—faithfulness (信), expressiveness (達), and elegance (雅).
Vertana (वर्तन): Means transformation, turning, or process. It evokes the fluid and sacred process of transforming meaning from one language to another.
Glosso (γλῶσσα): The root for tongue or language. It's the origin of terms like glosssary and polyglot.
Fanyi (飜譯): The direct and minimal term for translation. It's punchy and honors the long-standing tradition of translation in East Asia.

@FraEmme bello! E auguri in ritardo!

@xconde Thank you, it's beautiful here! We visited the blowhole in Kiama yesterday, at a wine tasting right now :)

Simulating Driven-Dissipative Quantum Spin Dynamics on Consumer Hardware
Physics simulations using classical mechanics is something that’s fairly easily done on regular consumer hardware, with real-time approximations a common feature in video games. Moving things to the quantum realm gets more complex, though with equilibrium many-body systems still quite solvable. Where things get interesting is with nonequilibrium quantum systems.
These open systems are subject to energy gains and losses that disrupt its equilibrium. The truncated Wigner approximation (TWA) is used as a semi-classical method to solve these, but dissipative spin systems proved tricky. Now however [Hosseinabadi] et al. have put forward a TWA framework (PR article) for driven-dissipative many-body dynamics that works on consumer hardware.
Naturally, even with such optimizations there is still the issue that the TWA is only an approximation. This raises questions such as about how many interactions are required to get a sufficient level of accuracy.
Using classical computers to do these kind of quantum physics simulations has often been claimed to the ideal use of qubit-based quantum computers, but as has been proven repeatedly, you can get by with a regular tensor network or even a Commodore 64 if you’re in a pinch.
