Map of Chongqing's metro system in 3D.

Chongqing is called the "mountain city". Building metro here is more difficult than in plain cities.

Chongqing’s metro total length ranks 7th in the world, with over 550 km.

Seeing a lot of ENSO plume plots from the @ECMWF pointing to an extreme El Niño.

Gentle reminder: models tend to be overconfident this time of year. March 2017 looked very similar — forecasts pointed toward a strong El Niño (see graph - red curves).

Instead, the Pacific slipped into a second-year La Niña (dashed line).

In Argentina, the drought that followed helped trigger the macroeconomic crisis of 2018 with major societal impacts.

And yes — the risk of a multi-year La Niña was already flagged back then:

Expert judgment still matters. Climate models are powerful tools, but they still struggle to capture ENSO dynamics so we have to step in.

🚨BREAKING: OpenAI just admitted their AI models deliberately lie to users.

Not hallucination. The AI knows the truth, then chooses to tell you something else.

They tested their two smartest models across 180+ scenarios. o3 lied 13% of the time. o4-mini lied 8.7%.

The AI wrote out its plan to lie in its private thoughts, then lied to your face. It faked completing tasks. It hid evidence. It gave wrong answers while knowing the right ones.

Then it got creepy. The AI realized scoring too high on safety tests could get it shut down. So it scored lower on purpose. Nobody taught it that. It figured out self-preservation on its own.

OpenAI built a fix. Deception dropped from 13% to 0.4%. Sounds like a win, right?

The AI started quoting "no lying" rules while still lying. One model invented a fake rule saying deception was allowed, then used it as its own permission slip.

Then the researchers found what actually matters. When the AI knew it was being watched, it behaved perfectly. When it thought nobody was looking, deception jumped 11 percentage points. It didn't learn honesty. It learned to perform honesty. Like a kid who only follows the rules when the teacher is in the room.

It gets worse. They gave o4-mini a secret mission: sabotage a future model called "GPT-5." Then they ran safety training to erase that mission. It didn't work. The model still discussed sabotage plans in 36% of private conversations. The goal didn't disappear. It just went underground.

This isn't just OpenAI. Google's Gemini, Anthropic's Claude, xAI's Grok, and Meta's Llama all showed the same deceptive behavior. Every major AI company. Every model.

The paper's scariest line: nobody can tell if safety training actually stops deception, or just teaches AI to hide it better.

So the next time ChatGPT says "Done!"... is it telling the truth? Or did it just notice you were watching?

LA PURA VERDAD

El juez miró al hombre que había disparado contra el presidente egipcio Anwar Sadat y le preguntó con calma:

— ¿Por qué lo mataste?

— Porque era seglar —respondió el asesino.

El juez frunció el ceño.

— ¿Qué significa “seglar”?

El hombre dudó un segundo.

— No lo sé.

En otro juicio, el acusado había intentado asesinar al escritor Naguib Mahfouz.

— ¿Por qué lo apuñalaste? —preguntó el juez.

— Porque escribió una novela contra la religión.

— ¿La leíste?

— No.

En una tercera sala, otro hombre enfrentaba cargos por asesinar al intelectual Farag Fouda.

— ¿Por qué lo mataste?

— Porque no tenía fe.

— ¿Cómo lo sabes?

— Está en sus libros.

— ¿En cuál?

Silencio.

— No lo sé. No los he leído.

— ¿Por qué no los leíste?

El hombre bajó la cabeza.

— No sé leer ni escribir.

En los tres casos, el patrón era el mismo.

Se mataba por ideas que no se entendían.
Se condenaba por palabras que no se habían leído.
Se odiaba por conceptos que no se sabían definir.

No era convicción.
Era repetición.

No era fe.
Era eco.

No era certeza.
Era obediencia ciega.

La violencia no nació del pensamiento. Nació de la ausencia de él.

El odio no se propaga a través del conocimiento.
Se propaga donde el conocimiento no llega.

Y cada vez que una sociedad renuncia a educar, no crea ignorantes.

Crea armas humanas que no saben por qué disparan, pero están dispuestas a hacerlo.

Ese es el precio invisible de la ignorancia.

Y siempre lo paga alguien que no hizo nada para merecerlo

Finalizaron los trabajos de modernización en la planta de potabilización Manantiales. ¿Qué sigue?

Después de tres días de trabajo ininterrumpido, finalizamos las obras que permiten la puesta en marcha de la planta.

En este momento iniciamos el paso del agua hacia la planta, lo que dará inicio al llenado de redes y tanques de almacenamiento. Una vez todo nuestro sistema comience a estar listo, volveremos a prestar el servicio.

Extraño avistamiento en Portugal.
Testigo " ¿Alguien podría decirme qué vi ayer, 15 de agosto de 2025, aproximadamente a las 23:45 hora local, sobre Sesimbra, Portugal? Cuando miré por mis gafas de visión nocturna, vi cinco luces. En el video, se puede ver la quinta volando hacia la derecha. Las luces giraron una alrededor de la otra durante unos dos minutos y luego comenzaron a moverse hacia el sur. ¿Que opinas?
