📚 I have a few misprinted (black and white) hardcovers of Geocomputation with R.

Happy to send them to readers in Europe.

Email me if you’d like one — if there’s lots of interest, I’ll draw randomly. Shipping costs optional.

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?

Queridas almas diversas! Como dice mi admirada @ujue.bsky.social este artículo de @civio.es es oro!

Y si tenéis que explicar lo que es la sensibilidad y la especificidad así como la importancia del umbral diagnóstico aquí tenéis la
animación perfecta 😍

Gracias por el trabajazo!
Pero qué cracks la gente de @civio.es con este articulazo sobre el algoritmo de diagnóstico de cáncer de piel que se desarrolla para el servicio vasco de salud.
Genial la visualización de datos y la historia completa 👏👏👏

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
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.

A very very intelillence words!!
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
