La IA (entendida como "ChatGPT y similares", definición un poco estrecha) *simula* empatía. Pero es una empatía servil, falsa. No es la empatía de tu amigo que te conoce: es Gríma Lengua de Serpiente.

Creo que el punto se entiende igual, pero no está de más recordarlo.

España 🇪🇸, en la vanguardia mundial de lo productores de energía solar

Somos el 4º país del mundo en generación solar per cápita ☀️
► Y 7º con mayor generación eléctrica

Las renovables generaron en 2024 el 56,8% de la electricidad que consumimos

Every Reason Why I Hate AI and You Should Too maybe it's anti-innovation, maybe it's just avoiding hype. But one thing is clear, I'm completely done with hearing about AI.

Un buen, largo repaso a las IA (lectura larga).

Comunicado sobre Taller: IA + EA Enseñar a usar aplicaciones de IA Generativa no es Educación Ambiental https://arteesetica.org/comunicado-sobre-taller-ia-ea/

La IA generativa no es sostenible ni se puede usar de forma ética. Enseñar a usar aplicaciones de IA generativa NO es educación ambiental. Están promoviendo un tipo de tecnología que constituye una factoría de ilegalidad y violación de los derechos humanos 🧵

hot take: the existence of multiple "distros" of linux and the ability to choose which one you like best is an ecosystem-destroying anti-pattern on the scale of (for the old heads who know) the ability to choose your own optimal favorite flavor of object model in LISP

Google Workspace now defaults to expensive plans ($20/month) instead of cheaper plans ($7/month) with promise of better AI or something. Downgrading is _really really_ hard, I had to dig super far into the UI. I was able to do it, but I suspect vast majority of people will just fail.

So […]

El PP acusa al Gobierno de “poner en riesgo la seguridad de España y sus aliados” por contratar con la china Huawei Los populares reclaman la comparecencia de cuatro ministros: Marlaska, Robles, Albares y Bolaños

Indocumentados que utilizan Windows, que tienen Whatsapp instalado en su vida, cuyas universidades en donde gobiernan tienen servicios completos de Google o de Microsoft, dicen que si Huawei.

Estamos gobernados por mediocres que no saben ni mirarse al espejo.

Enough AI copilots! We need AI HUDs

Nice blog post by @geoffreylitt.com : "Enough AI copilots! We need AI HUDs"

Will have to dive deeper into the "Ubiquitous Computing" concept, crazy that they were thinking about this in 1992 already

Everything about this launch is amazing. Connections with all the social web, the partnership with Tinybird, the revenue numbers... Congrats to everyone involved 👏

Todo es un infierno comunista para los nacionales. Y para los guiris esto es la isla de Man.

Buen resumen

A Plasticene Lexicon As plastic pollution in the environment has increased rapidly in the last half century, so too has the study of the effects of plastic on marine, aqua…

The massive amount of plastics being dumped on us and the environment by the petrochemical industry (the same folks cooking our #climate with fossil fuels) is so planet-altering there is now a case for it getting it's own geological periodization:

A map of Europe showing the percentage of ultra-processed foods in the diets of different countries. The colors represent different ranges: Blue: Under 25%, Yellow: Over 25%, Orange: Over 50%. The map highlights countries with high consumption of ultra-processed foods, such as the UK, Ireland, and Belgium, and those with lower consumption, such as Portugal and Greece.

Consumption of ultra-processed foods (UPFs). WTF UK?

(via @Guardian)

The image presents a bar chart illustrating the percentage of new cars sold globally that were electric, including both fully battery-electric and plug-in hybrids, with data projected for 2024. The chart shows a selection of countries and regions from highest to lowest percentage. - Norway leads with 92%. - Sweden follows with 58%. - China shows 48%. - The United Kingdom and Switzerland each have 28%. - The European Union has 21%. - Canada has 17%. - Australia is at 13%. - The United States has 10%. - South Korea registers 9%. - Brazil is represented at 6%. - Japan stands at 3%. - India is at 2%. The data source cited at the bottom is the International Energy Agency's Global EV Outlook 2025.

What share of new cars in your country are electric?

LeetCode binary tree problems sometimes make my brain hurt, especially combined with learning Rust 🥲

Microplastics are here to stay; that's why we need to eat them responsibly in the classroom

Yes, if you make RTD versions track branches and not tags...

Note that you can now rename versions, so all you need would he a 1.x branch, and call it v1 on RTD

And aside from the language of choice, I think my algorithmic thinking is more rusty than I was willing to admit. Hope I can regain some of it.

The side effect is that now I get a feeling of what my Python students go through when they learn the language for the first time. Which can only be a good thing, especially for them!

Spending some time learning Rust again, this time with LeetCode. I won't lie: this is only fun for very wicked definitions of "fun". Pleasing the borrow checker is hard!

The temptation of solving with AI is big. But the "aha" moment requires struggle, me thinks!

Also, Rust docs are so good 💯
