I like to think the source code for reality has checks like this one: when it doesn't trigger, it raises a `RunTimeError`: "math instability found, please reboot the Universe."

There's a lot of big news today/this week, but Apple just dropped a nuke of a paper about LLMs & LRMs, specially around "high-complexity tasks where both models experience complete collapse." This is the biggest sign yet that if AI ever lives up the hype, it won't be via those approaches:
The Illusion of Thinking: Understanding the Strengths and Limitations of Reasoning Models via the Lens of Problem Complexity
Recent generations of frontier language models have introduced Large Reasoning Models
(LRMs) that generate detailed thinking processes…

And what do we do about the journals that send you proofs which contain more (grammar and style) mistakes than the original draft? Perhaps we are not paying them enough?

I have to reply to ~20 mails and I know I will have to spend the entire day doing that, so I'm just looking for ways to avoid starting the day.

El estado tendría que tener un cuerpo de programadores e ingenieros de software igual que tiene uno se abogados
¿Veríamos normal que el derecho en el estado lo llevase Legalitas? Entonces por qué el software lo lleva Deloitte
Pero claro "es más barato" subcontratar, hasta que llevas 200 proyectos

8 millones de euros para desarrollar un sistema que tiene menos funcionalidades que el anterior y se cae contínuamente.
Eso pasa por subcontratar consultoras externas (Deloitte), que cobran y se desentienden. Da igual que el resultado no satisfaga las necesidades reales mientras cumpla el pliego.

This is the best spam I have ever received.

It's a shame they keep getting my surname wrong, that's the only reason I'm not replying. So close.

Inclusive distributions are now forbidden, integrating over the whole phase space can mess up with your funding 🙃

I have several outdated packages in conda forge because I wanted to port them to the new recipe format but I can never find the time 😬
Maybe I should just bite the bullet and update them the old way for now...

Given the state Windows is in I would say that usability was actually better 15 years ago. People should be happy!

Why do people who not use linux have this idea that linux has not moved in progress past like 2010
aka no apps on linux and it's not usable without 10years of config and tweaking
