I'm opening a #Sass micro-app-store, all powered by #AI #Agents. The general development platform is Ruby on Rails. Which app would you be interested in purchasing? I'll give you 100% ownership of the code and a week of development time included to localize any needs you mayhave:

A man spends 50 years teaching at MIT.

He knows his time is running out.

So he records one last lecture — everything he knows, distilled into a single hour.

He died 5 months later.

This is that lecture.

The most important hour you'll watch this week. 👇

Build Long-Term Self-Discipline

[Daniel Mayakovski @DaniMayakovski]

"El sionismo, como ideología reaccionaria, encajaba perfectamente con el colonialismo británico y con los planes del imperialismo estadounidense en la región. Los sionistas pidieron ayuda a la Rhodesia y Sudáfrica colonial para construir su sociedad racista".

Ghassan Kanafani, fundador del Frente Popular para la Liberación de Palestina, expone las raices racistas y coloniales del apartheid sionista.

Nassim Taleb ran a simple test: take two completely random, unrelated columns of numbers - noise, nothing else - and measure their correlation.

with a small sample, you'll routinely see correlations of 0.4, 0.6, even higher. from pure randomness.

now the trap. give a researcher many variables and few data points - say 38 variables, 18 points each, which he says is far more common than you'd think - and let them hunt for the highest correlation. they'll always find a "strong" one. it means nothing. it's just the max of a pile of noise.

"when you hear the word correlation, be suspicious." by his estimate, about half of published research is nonsense for exactly this reason.

Hoy querria recomendar este libro de filosofia de la mente el cual aborda el tema del pensamiento y como este funciona, llevandolo a hablar de distintos temas que van desde la inteligencia artificial hasta la evolucion.

Attention is a lookup. Each token builds a query, compares it against every key in the sequence, and pulls value vectors weighted by the match. Stack that 96 layers deep and you get a frontier model.

Video covers the full pipeline: Q/K/V, attention scores, encoder blocks.

[Mathematica @mathemetica]

Tensors generalize vectors as lists and matrices as grids into higher-order arrays like 3D cubes.

Comparisons include a vector as a list, a matrix as a grid, and a 3-tensor as a cube, along with the stress tensor σij on a cube featuring arrows for components like σ11 and σ23, the product derivative rule, the Riemann curvature tensor R(u,v)w = ∇u ∇_v w − ∇_v ∇_u w − ∇[u,v]w, quantum superposition 1/√2(|00⟩ + |11⟩), and algebraic operations like the tensor product.

It is used to analyze internal forces and deformations in engineering materials and to describe the geometry of spacetime under gravity in general relativity.

#ULTIMAHORA En un acto de disidencia sin precedentes, el mayor de la Fuerza Aérea de los EE. UU. en servicio activo Jason Watson fue detenido en las escalinatas del Capitolio tras exigir el juicio político y la destitución de Donald Trump. Su detención, realizada a costa de arriesgar su carrera para cumplir con su juramento constitucional, marca un momento histórico.

Andrew Ng, Stanford professor, co-founder of Google Brain:

"OpenAI pays $900K to hire people who can do this. I taught it to millions of them, for free, before OpenAI even existed."

this free stanford lecture holds the entire "AI trading" gold rush the 2026 gurus are selling. and the man teaching it isn't pushing a course. he co-founded google brain, then coursera, and gave machine learning away to millions of people for nothing.

what he teaches, calmly, at a chalkboard, is that machine learning is not a prophet. you feed a model examples, it fits a pattern, it guesses the next one. that is the whole "AI that reads the market" pitch, stripped of the mystery. powerful, useful, and completely ordinary once you see it.

and it is old. ng was teaching this in 2008, renaissance was trading on it in 1988, and every lecture is free. same story i told in the article above. you were never locked out of AI. the door was open the whole time.

here is what the bot sellers hide. everyone has the same free algorithms, so the model was never the edge. what wins is the data you feed it and the discipline to trust it across a thousand trades without flinching. that is the part you can't download, and the part no one will sell you.

Hoy es el aniversario de uno de los crímenes más atroces cometidos por EٍEUU.
El 3 de julio de 1988, el vuelo 655 de Iran Air fue derribado por un buque de guerra estadounidense sobre el Golfo Pérsico, causando la muerte de sus 290 ocupantes, entre ellos 66 niños.

Hay historias que merecen ser narradas.
Durante las próximas semanas os voy a contar La Odisea, canto por canto, acompañando cada episodio con una o varias obras de arte. Un viaje por el poema de Homero a través de la pintura.

Nassim Taleb asked a room full of quants: to trust an average, a normal bell curve needs ~30 data points. how many does an 80/20 "fat-tailed" world need?

people guessed 200. 1,000. the real answer: 100 trillion.

that's 10¹⁴ - because in fat-tailed data, one rare event dwarfs everything else, and until it shows up your sample is a lie. "you observe, you observe, you observe… until the crash."

worse, the deception only runs one way. a wild distribution can disguise itself as calm - a calm one can't fake being wild. so the data almost always fools you downward, into thinking there's less risk than there is.

the fix: stop estimating the average from the average. it doesn't work where it matters.

"El informe de la ONU dice que los soldados israelíes disparaban en Gaza a los niños palestinos como si fuese un tiro al blanco, competían entre ellos disparándoles deliberadamente a sus extremidades".

El senador australiano David Pocock denunció el informe de la ONU del pasado 18 de junio, donde se expone como los soldados sionistas juegan al tiro al blanco con los niños palestinos de Gaza.
