UN CIENTÍFICO DANÉS PROGRAMÓ A CLAUDE PARA QUE BUSQUE TRABAJO POR ÉL Y LO ACABA DE HACER PÚBLICO

Mandar CVs es uno de los trabajos más absurdos del mundo: copiar, pegar, adaptar, personalizar, repetir. Todo manual, todo lento, todo para que lo lea un algoritmo antes que un humano.

→ Analiza la oferta de trabajo automáticamente
→ Genera un CV personalizado para cada puesto
→ Redacta la carta de presentación adaptada al contexto
→ Todo lo hace Claude por debajo, sin que toques nada
→ Open source, ya en 3.5k stars en GitHub

El tío que debería estar buscando trabajo ha construido la herramienta que lo busca por él.

Aquí te explico cómo funciona 👇(repoo al final del hilo)

Did you know?

An explosion of zinc fireworks occurs when a human egg is activated by a sperm enzyme, and the size of these “sparks” is a direct measure of its ability to develop into an embryo.

In other words, life begins with a flash of light.

@Aqui_mi_casa Einstein disait "S'il faut penser qu'un bureau dérangé appartient à une personne dérangée, que penser d'un bureau vide ?". Il parlait de la pièce, son bureau ayant été tout le temps dans un bordel incroyable.

@bernathoustra Remettre en question l'utilité de la philosophie comme vous le faites, c'est philosopher. C'est l'essence même de la discipline.

Santé camarade.
On va finir par y arriver.

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.

CHINA JUST LEAKED THE FUTURE OF WEB APPS.

Alibaba open-sourced PageAgent and 99% of SaaS founders are sleeping on this.

It's a JavaScript AI agent that lives INSIDE your webpage. Users control your entire interface with natural language.

↳ No browser extensions needed, screenshots or multi-modal LLMs, headless browser setup, and also no backend rewrite required

Just drop it in your HTML with ONE line of code. What took 20 clicks now takes one sentence.

"Click login, fill in my credentials, submit the form"
Done. This is not a demo, it is production-ready.

↳ Turn any SaaS into an AI copilot in minutes
↳ Smart form filling for ERP, CRM, admin systems
↳ Voice commands and accessibility built in
↳ Multi-page agent tasks via Chrome extension
↳ MCP server support for external control
↳ Bring your own LLM (Qwen, GPT, Claude, anything)

Every founder building AI features just got a shortcut.

Every developer manually building copilots just got replaced.

The integration looks like this:

That's it. Your app now has an AI agent.

Probability distributions capture the essence of randomness and are central to all statistical work.

A comprehensive visual reference shows the shapes of many continuous and discrete distributions, each with key parameters such as location, scale, degrees of freedom, shape, and rate labeled on the plots.
It includes the normal, t, uniform, beta, gamma, exponential, Poisson, binomial, chi-square, F, Weibull, Cauchy, logistic, log-normal, Pareto, and specialized forms like noncentral chi-square, censored normals, and half-Cauchy.

It is used to guide the selection of appropriate probability models when analyzing data in Bayesian statistics, finance, engineering, and scientific experiments.

Jour 139, orbite 2155 – Après les photos (disponibles en HD sur mon compte Flickr), je suis très heureuse de pouvoir enfin partager avec vous le timelapse de l’aurore la plus spectaculaire (jusqu’à présent !) de la mission εpsilon !

🤩 Difficile de ne pas céder à la magie de l’instant en regardant ce ruban de lumière verte onduler et danser sous nos yeux... Activez le son pour vivre pleinement l’expérience : la musique a été choisie avec soin pour évoquer les émotions que j’ai ressenties en admirant ce spectacle depuis l’espace 💚

@holytrowel @Lilith_Lechat Exactement. Quoi de plus énervant qu'un bon gros connard qui met en danger tout le monde juste parce qu'il pense que quand il arrive à fond de balle sur quelqu'un, ce dernier doit s'excuser et se pousser. Le flux entier de la route doit vivre à son rythme.
