Cuando leo que la crisis de vivienda se arregla construyendo más.

“If we cannot even in principle be free from external manipulation and anti-scientific claims — and instead remain passive … and welcome corrosive industry frames into our computer systems, our scientific literature, and our classrooms — then we have failed as scientists and as educators.” 5/🧵

“Of course, we have to teach our students about AI technologies. Teaching about AI technologies should be just like how we teach ‘no smoking’ or the causal links between lung cancer and smoke; yet, we do not teach students how to roll cigarettes and smoke them.” zenodo.org/records/1706... 20/🧵

The most insanely frustrating thing about the #ClimateCrisis is how the breakthrough we so clearly need isn’t technological. It’s just a collective willingness, a determination even, to change in ways that would clearly be SO MUCH BETTER than the clear and obvious consequences of NOT changing.

It’s awesome to see this — but seriously, it’s so damn frustrating that we have to fight this fight in every city when the science couldn’t be clearer. Get the cars out, make more money for local shops, and build cities that are exciting, healthy, and happy for everyone.

Tell me you are storing passwords in the clear without telling me you are storing passwords in the clear...

This dumb password rule is from O2 Spain. When registering in *Mi O2* app, password length must be exactly 7 or 8 characters (numbers and letters only). As O2 is part of Telefónica (Movistar), it seems to use the same backend (at least in Spain), so it has the [`same password requirements`](https:

There are simple changes we can make to our cities that will have vast and ongoing positive effects on the lives of community members. Community leaders with vision are pulling up concrete and replacing it with plant life.

Every year, billions of vehicles worldwide shed an estimated 6 million tonnes of tire fragments. These tiny flakes of plastic, generated by normal driving, account for 28% of microplastics entering the environment globally. Heavy vehicles eg SUVs/EVs especially. Via @us.theconversation.com

Se me revuelve el estómago de la rabia. Esta gente, que se dedica sistemáticamente a esparcir mentiras y odio, se monta una fundación contra la censura, para la libertad, para apoyar el periodismo... Con dos cojones. Y gracias a eso, quienes les donen tendrán deducciones fiscales. (sigo)

Human-made global warming ‘caused two in three heat deaths in Europe this summer’

Está vez ha caído hasta la web de correos. Empiezo a pensar que hasta que Tebas no tire la web del Marca, no va a pasar nada.

The 2025 Happy City Index is in, and @momentummag.bsky.social is pointing out that many of the world’s happiest cities are also some of the best places to ride a bike. Vancouver is #11, the highest ranked city in North America (cue the usual debates).

En los últimos 4 años, Madrid ha perdido 78.616 árboles maduros según datos del propio Ayuntamiento. No hablamos de plantones, sino de árboles grandes y verdes que tardaron décadas en crecer y que proporcionaban servicios ecosistémicos irreemplazables. Esto es ecocidio urbano.

Smart cities know that, as hot as they already are, they’re just going to keep getting hotter. Greening the city not only cools it down, it cleans the air, quiets the noise, improves mental health & happiness, saves public money, & more. Strand Aldwych, London. 2021 vs. 2025. Via @modacitylife.com

Well, this horrible idea refuses to die so we should refuse to let it pass and start organizing again. ec.europa.eu/commission/p...

Què diferente sería Madrid si se lo pusiéramos fácil a la gente para ir así sin jugarse la vida.

“As mayors of 2 of the world’s great cities, we see every day how the climate emergency is already reshaping people’s lives…From deadly heatwaves & devastating floods to rising inequality & health crises driven by air pollution…” @annehidalgo.bsky.social & @london.gov.uk call out campaigns of lies.

As our cities get hotter and hotter, dark coloured buildings make no rational sense, even if you like that aesthetic (I do). The same goes for dark coloured roofs. And dark coloured streets and parking lots with dark coloured asphalt. That really should be obvious.

Curiosamente la mayoría de la gente cree que su huella de carbono depende de rehusar bolsas, beber en pajitas de papel y poner bombillas LED. Los datos muestran una realidad muy distinta: menos coche y menos carne. Para eso, claro está, hay que darle alternativas a la gente.

Here’s a good question — why is riding a bicycle in the city turning into [actually, being deliberately turned into] a culture war? Read this @momentummag.bsky.social article. It doesn’t need to be this way. It’s just smarter transportation that makes urban movement easier for EVERYONE.

So What Do We Know QC To Be Good For? - Simulating quantum physics and chemistry - Breaking current public-key encryption (RSA, DH, ECC) - Eventually, modest (square-root) speedups from Grover - We’ll have to get lucky for most other applications! (The world has been systemically lied to about this)

One reason I think it’s important to continue to highlight the disparity on our streets is that most people just don’t see it. Despite it being obvious to some, so many people don't have clarity because we have done such an incredible job of normalizing this imbalance.

No sé qué es peor: que Renfe (empresa estatal) dé su información en la red social de Musk, o que Adif (empresa estatal) refiera a ella para más información sobre un corte de línea

Why do we pretend heatwaves are fun – and ignore the brutal, burning reality? | Zoe Williams

Y aquí va mi pregunta: cuánto del nivel de cabreo general se deberá a la absoluta tolerancia hacia la contaminación acústica que hay en este país, en el que, por ejemplo, vehículos como las motos pueden hacer el ruido que les salga del potorro sin que nadie les diga ni mú a sus propietarios.

En España, el verdadero lujo solo al alcance de unos pocos es el silencio.

Suscribo totalmente esto.

Si algo nos identifica como país (y nos diferencia de cualquier otro más al norte) es la altísima probabilidad de que, vayas donde vayas y estés donde estés, haya alguien cerca metiendo ruido (obras, música a tope, motos ruidosas, camiones, aparatos varios, etcétera, etcétera, etcétera).

El titular es alarmista porque ChatGPT no "destruye" físicamente tu cerebro. Pero esas comparaciones con la calculadora, los libros o la enciclopedia son ridículas, la verdad. Necesitamos un poco de seriedad para analizar el fenómeno.

I hate the summers in Madrid

This. Decir que p.ej. en Madrid no necesitamos carril bici porque "actualmente poca gente usa la bici" es un argumento ridículo. Yo no uso la bici porque meterse en el tráfico con los coches en Madrid es jugarse la vida. Si hubiera suficientes carriles bici, la usaría

Never forget, when you’re being asked to prove that safe bike-lanes or pedestrian crossings across unsafe conditions are ‘needed,’ it's hard to justify a bridge by the number of people swimming across a raging river. #TheTruthAboutTraffic

En Londres ya hay tantas bicis como coches en la calle. Otra excusa que se le cae al alcalde de Madrid: el tamaño de la ciudad tampoco es la razón por la que no hay bicis en una ciudad. A ver si en algún momento se da cuenta de que todo tiene que ver con él mismo.

Fui a casa de mis padres el pasado domingo y no me quito de la cabeza que 8 de 12 los pisos de un bloque miserable de Santa Coloma tengan alarma de Securitas Direct. Cómo se la han colado a las clases populares. Si tienes un chalé, pues aún lo entiendo.
