@amartino La 4 también tiene una aproximación como la 2. El rendimiento geométrico ≈ rendimiento aritmético - la mitad de la varianza.

Civilized people hate voice notes because they’re inherently rude. A voice note is easy to send but hard to receive, since one must interrupt oneself and listen. To send someone a voice note is to say "My time is more valuable than yours." It’s insulting.

@elerianm if there's anything worse than being an egiptian supporting England is coming back home defeated and having to support Spain next Sunday

Argentinians are world class trolls. None of them actually give a shit about the Middle East. All they know is that showing an Israeli flag to an Arab has the same effect as spraying them with the Rage Virus from 28 Days Later.

Anticipo: la semana que viene podría afectarnos un “anticiclón térmico”

Si se confirma, viviríamos una fuerte ola de frío polar desde el Lunes 22 de Junio. Como vemos en el mapa, el aire gélido alcanza incluso al sur de Brasil.

¿Qué es un anticiclón térmico? ❄ El aire frío siempre es más pesado, entonces helará por completo las capas bajas de la atmósfera (cercanas a suelo)

Las nubes, al desaparecer durante la noche, le quitan al suelo la posibilidad de conservar algo de calor.

La ventaja: al dominar un profundo sistema de altas presiones, las tardes serán soleadas.

Cada amanecer presentaría sensaciones térmicas bajo cero, y por las tardes apenas 13 o 14 grados.

Admiro profundamente a @FranColapinto y le deseo siempre lo mejor no porque convoque 500,000 personas en Buenos Aires o porque sea picante en sus declaraciones, aunque me parecen espectaculares ambas cosas, sino por esto.

50% of all relationship advice on Reddit is “leave.” 15 years of data, 52 million comments, and the trend line only goes one direction.

A researcher filtered r/relationship_advice down to 1,166,592 quality comments and tracked what people actually recommend. In 2010, “End Relationship” sat around 30%. By 2025, it’s approaching 50%.

“Communicate” dropped from 22% to 14%. “Compromise” collapsed from 7% to 3%. “Give Space” fell from 25% to 13%. Every category that requires patience lost ground every single year.

The one category growing faster than “leave” is “Seek Therapy,” which went from 1% to 6%. The subreddit is slowly learning to say “this is above my pay grade.”

Train a model on this dataset and it would absolutely tell people to break up. The training data is 50% “leave” and climbing. The model wouldn’t be broken. It would be accurately reflecting what 52 million commenters actually believe about your relationship.

A 50% prior that you should leave, a 14% prior that you should talk about it, and a 6% prior that you need a professional. That’s not LLM psychosis. That’s the median human opinion on your relationship, backed by the largest advice dataset ever assembled.

This is one of the most important studies in sleep science.

Van Dongen et al. ran the experiment that changed how we understand chronic sleep restriction. They had subjects sleep 4h, 6h, or 8h nightly for 14 days, testing cognitive performance every 2 hours.

The 6h group’s reaction time deficits by day 14 matched subjects who had been awake for 24 hours straight. The 4h group? They performed like someone awake 48 hours.

But here’s what makes this study terrifying.

The Stanford Sleepiness Scale ratings in Panel B plateau after day 3-4. Subjects stopped feeling more tired even as their cognitive performance continued deteriorating through day 14. Your subjective experience of fatigue is a lagging indicator that eventually just… stops updating.

This explains why chronic undersleeping feels sustainable. You’ve adapted to feeling tired. Your prefrontal cortex hasn’t adapted to being impaired.

The PVT (Psychomotor Vigilance Task) in Panel A measures lapses in attention. These are the moments where you’re staring at a screen and your brain simply checks out for 500ms. Every additional day of 6h sleep adds more lapses. The curve never flattens.

Panel C and D show working memory and processing speed. Same pattern: continuous degradation with no subjective awareness.

The practical implications:

If you’re sleeping 6h and think you’re functioning fine, you’ve lost the internal calibration to know you’re not. The subjects in this study would have told you they felt “okay” while performing like they’d pulled an all-nighter.

For anyone doing cognitively demanding work, this means you cannot trust how you feel. You need to track objective markers: error rates, decision latency, problem-solving throughput.

Sleep need is biological, not negotiable. Most adults require 7-9 hours, and the research shows no population-level adaptation to chronic restriction. “I only need 6 hours” is almost always “I’ve forgotten what baseline cognition feels like.“
