Es realmente necesario cortar el césped tan a menudo como se hace en España? Diría que el césped algo más alto elimina mejor el calor. No entiendo esa obsesión por tenerlo como si fuera un tapete.

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.

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.

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.

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)

Epidemiologists and climate scientists attributed 16,500 out of 24,400 heat deaths from June to August to the extra hot weather brought on by greenhouse gases. Continue reading...
