Confirmado @luisvaldes.bsky.social , Volkswagen Alicante no quieren vender ID.buzz,me ofrecen una Caddy ehybrid blanca de km 0. yo necesito adaptarla,pero ni he podido entrar como piloto en la ID.buzz por estar pegada al coche de al lado.Y además diciendo que no creía que se pudiese adaptar.grgrgr

Researchers value null results, but struggle to publish them
“If it had been widely disseminated in my field,” they lamented, “it would have saved me 2+ critical research years!”

Researchers value null results, but struggle to publish them
Survey finds that fear of reputational harm and a lack of support and publication platforms are among respondents’ key concerns.

Por una lesión vuelvo a un vehiculo con grua para subir una silla de ruedas. Por lo que barajo la ID.buzz como vehículo único (pero para moverse por Alicante uffff), eBerlingo+eléctrico(400km); o una Híbrida enchufable. Ahora tengo Tesla MYP 2022 @luisvaldes.bsky.social ¿qué me recomendáis?

There are thousands of freshwater fish species in North America alone. My historical dataset from Missouri alone had 200 species. And they're all more interesting than bass

Yes, the interoperability between Julia and many other languages is amazing! I often work in the other direction, calling for example these from within Julia code:
- R (github.com/JuliaInterop...)
- Python (github.com/JuliaPy/PyCa...)
- Matlab (github.com/JuliaInterop...) from Julia.

Spain has the most hours of free electricity in all of Europe, and also the lowest average electricity price.
Solar + wind = saving money
Gas + nuclear = wasting money
Solar + wind = saving money

Spanje heeft het meeste uren gratis stroom en ook gemiddeld de laagste stroomprijs.
Voor de rest ontlopen de West-Europese landen elkaar nauwelijks, ondanks flinke verschillen in de nationale power mix.

A book I've grown to like very much is Regression and Other Stories by @statmodeling.bsky.social, Hill and @avehtari.bsky.social. I've never read it cover to cover. Instead, I occasionally grab it and open a random page. Almost always there's a nugget of wisdom.

Hate to break it to you. That AI tool is not artificial intelligence.
I studied an AI module as part of my computer science degree in 2003
You're using an LLM. It is a subset of AI. And yes, it's changed the game
It has knowledge of the world. But it does not understand the world.
Big difference
