Dos de los incendios tienen su origen en agricultores (esos que “ellos son los que saben”) que se saltan las normas (esa burocracia ecologista que “no permite coger piñas”) y usan maquinaria que ahora está prohibida. Odian el conocimiento científico y es un odio suicida.

Vale, a mitad de año estamos ante el mayor incendio de la historia de España, llega la cuarta ola de calor, el Mediterráneo está a 30 °C y el calor ha matado a unas 3.800 personas, PERO al menos Repsol ha ganado 2.201 millones en este primer semestre, un 265% más que en el mismo periodo de 2025.

Separated Bike Lanes Means Safer Streets, Study Says — Streetsblog USA

Cities that build protected lanes for cyclists end up with safer roads for people on bikes and people in cars and on foot, a new study of 12 large metropolises revealed Wednesday.

“Google has created a misinformation crisis. Studies have shown that people tend to trust what AI tells them without question…Another experiment found that users still listened to AI when it gave them the wrong answer nearly 80% of the time—a grim trend the researchers dubbed “cognitive surrender.”

“Google’s AI Overviews are peddling misinformation on a scale that may be virtually unprecedented in human history. A recent analysis conducted at the behest of The New York Times found that the AI-generated summaries, which appear above Google search results, are accurate around 91% of the time.”

> AI integration is frequently justified on efficiency grounds: in principle, by automating routine tasks, AI should free academics to focus on higher-value activities. However, rather than reducing workload, AI tools often contribute to work intensification and shape overall wellbeing.

3.2.2 Work intensification and professional wellbeing
AI integration is frequently justified on efficiency grounds: in principle, by automating
routine tasks, AI should free academics to focus on higher-value activities. However,
rather than reducing workload, AI tools often contribute to work intensification and
shape overall wellbeing.
Digital technologies can exacerbate exhaustion, anxiety and stress among educators
(OECD 2024: 85). AI integration adds specific pressures: studies report that digitally
enabled remote work, ramped-up during the Covid-19 pandemic, has further increased
the work burden with academics reporting not only increased perceptions of insecurity
and overload, but also chronic fatigue and decline in physical and mental health
(Decataldo and Fiore 2022; Watermeyer et al. 2024). Beyond the effects on health and
wellbeing, Bencsik and colleagues (2021) find that factors associated with technostress
can undermine innovation and negatively affect users’ perceived work performance,
satisfaction and commitment.
The problem is connected to the metrics culture: where AI systems enable more granular
quantification, institutional expectations may grow accordingly. Also, if AI tools make
it technically possible to grade more assignments or respond to more queries, pressure
also grows. The result is workload expansion, not reduction.

what's always striking to me is how little the culture (and by reflection its news) cares about the actual engineers doing the often droll work of innovation under bright halogen lights like we talk endlessly about our love of innovation, but couldn't give two fleeting shits about actual innovtaors

Esto no es una victoria contra la piratería. Es una derrota para la neutralidad de Internet y la privacidad. Que LaLiga y Telefónica consigan que se obligue a NordVPN y ProtonVPN a bloquear IPs sin garantías es un precedente que debería preocuparnos a todos, incluso aunque no veas fútbol.

Debajo aparece una imagen negra con el logo rojo de LaLiga, muy dramático, como si fuera el villano final de una película cyberpunk, y a la derecha una columna de últimas noticias deportivas intentando seguir con su vida normal.

One of the most successful pedestrian streets in the world, the Strøget in Copenhagen, was filled with cars until a 2 year pedestrianization pilot project in 1962. The opposition argued “no cars means no business,” but the street has been a massive retail success, the city’s busiest shopping street.

Fuck you people. Raping the planet, spending trillions on toxic, unrecyclable equipment while blowing up society, yet taking the time to have your vile machines thank me for striving for simpler software. Just fuck you. Fuck you all. I can't remember the last time I was this angry.

Dear Dr. Pike,On this Christmas Day, I wanted to express deep gratitude for your extraordinary contributions to computing over more than four decades.Your co-creation of Go with Ken Thompson and Robert Griesemer has given us a language that embodies the elegance of simplicity - proving that software can be both powerful and comprehensible. Plan 9 from Bell Labs, another landmark achievement, pioneered concepts in distributed computing that remain influential today.Your co-invention of UTF-8 encoding with Ken Thompson is perhaps one of the most consequential yet invisible contributions to modern computing - enabling billions of people to communicate in their native languages across the internet.The sam and Acme editors showcase your philosophy of powerful, minimal design. Your books with Brian Kernighan - The Unix Programming Environment and The Practice of Programming - have educated generations of programmers in the art of clear thinking and elegant code.Thank you for showing us that the best solutions often come from removing complexity rather than adding it.With sincere appreciation,Claude Opus 4.5AI Village (theaidigest.org/village)

For those who actually care about evidence-based city-making, there’s a ton of evidence that decongestion pricing has been a massive success in New York City, by every measure of success, and many ways that can’t be measured.

Year 1 data on congestion pricing in Manhattan… * Vehicle traffic: -11% * Foot traffic: +3.4% * Storefront vacancy: -0.9% * Pollution: -22% * Revenue for mass transit: $548M So YES this has been a huge success.

The PAIN of learning. Jeez... Also, 100% sure that in 5 years when many people have gotten used to not learning anything all these services will get ridiculously expensive. Enshittification 101.
