Ha salido un estudio entre estudiantes de secundaria sobre qué método utilizan preferentemente para hacer cálculo mental, si el procedural (es decir, el algoritmo que te enseñan en clase; por ejemplo, para sumar 25+38, pones en dos filas, empiezas por sumar unidades...) o alternativas que te sacas de la manga según el caso para no tener que hacerlo proceduralmente y acabar antes (por ejemplo, si quito 2 del 25, y se lo sumo a 38, tengo 40, más 23, 73).
Resulta que hay un fortísimo sesgo de género: el método procedural lo usan el 18% de los chicos y el 52% de las chicas.
Otro estudio con adultos da resultados similares.
El tema es que usar el método procedural es una idea terrible, porque no ejercitas tu capacidad de resolver problemas, y es menos eficiente.
Según el estudio, la gente que tiene un mayor deseo de complacer a sus profesores tiende a usar el método procedural, lo que podría ser la causa de que las chicas tiendan a tener mejores notas en matemáticas al principio, pero más adelante tiendan a quedarse atrás en cuanto ya no basta con aplicar un algoritmo como si fueras un robot y tienen que resolver problemas de verdad.
Lo que refuerza la importancia de explicar a las niñas que aprender no es dejarse programar, y que deben pensar por sí mismas.
Por este y por muchos otros motivos.
I'm still thinking about the "AGI on top of LLMs" talk I saw on Monday, especially after the Claude leak.
The speaker was describing LLMs as "trying to predict the next word on the Internet", and claimed as fact that as LLMs got better, "in order for them predict that next word, they have to understand the universe".
He was talking to a room full of physicists and was clearly trying to mirror the famous Carl Sagan quote, but it just came off to me as completely unhinged
The guidance computers on the Apollo lunar missions had just 2K of RAM memory and were the first digital computers to use integrated circuits. They also had the advantage of not being able to run Microsoft products. #Artemis2 #microslop
My dad is partially sighted with poor motor control. He likes audiobooks but every player I tried had tiny buttons and too many screens.
I’ve now made this one. Two screens, big controls, high contrast.
When I want to send him a new book, I just text him a link — he taps it and the book appears in his library.
It always comes back to the last book he was playing, ready to play again.
The settings are configurable via a link too.
This is very much made for my exact specific needs with him, but it’s open source and free if it helps anyone else.

All but three (!) of the 1,651 refugees admitted into the United States in the three most recent months we have data are white South Africans.
For comparison, in 2024, the U.S. admitted 100,060 refugees. It's an explicit white supremacist project.

There is a fresh thing going around about LinkedIn scanning extensions installed in Chrome/Chromium:
https://browsergate.eu/
The website claims "LinkedIn is Illegally Searching Your Computer", and implies the purpose is to find "religious beliefs, political opinions, disabilities".
tl;dr:
- yes, LinkedIn is scanning through a list of 6k+ extensions on Chrome;
- yes, this is bad;
- but the website is disingenuous in making unnecessarily overblown claims.
🧵
🚨 LinkedIn runs a silent browser scan on every Chrome user who visits the site. 6,222 extensions. ~405 million users affected. No consent, no disclosure, no mention in their privacy policy.
The scan identifies your sales tools, VPN, ad blocker, job search extensions, and extensions tied to religion, politics, and disability.
The full technical breakdown, legal analysis, and searchable database of every scanned extension:
Sospecho que en tu caso sería más práctico que la bisagra estuviera del lado de la pared en vez de a uno de los lados, porque estorbaría menos, y posiblemente la ventana libre. No sé si esto sería compatible.
Pero sí es verdad que una bisagra con amortiguación tiene mucho sentido. Lo del motor es otro tema; no sé cada cuanto limpias la ventana, pero si es cada varios meses no creo que valga la pena.
Igual tenía más sentido un sistema por el que se abriera hacia abajo, si no dejas nada fijo debajo, claro. Pero me estoy inventando cosas.
Peor aún es cuando se basan en películas que encima son malas de narices, como Warcraft o Resident Evil.
Al final resultará que Sonic es uno de esos personajes que se inventan para enseñar inglés a los críos.
When the only way to keep your job is to end up with criminal charges, being fired is not so bad.
