ROBO A CROACIA: Errores en física.

Si nos vamos a poner detallistas con el tema de los sensores de las pelotas, de si hubo un mínimo roce y aplicar el reglamento al milímetro, también tenemos que aplicar física al milímetro.

La pelota Trionda usa tecnología de balón conectado con un sensor de movimiento de 500 Hz que da información al VAR sobre movimiento/contactos del balón. Ese sensor no “ve” una cabeza: mide aceleraciones, rotaciones y patrones de movimiento. Por eso, si la pelota pasa muy cerca de una cabeza, puede haber perturbaciones aerodinámicas, vibraciones o ruido mecánico. En principio, eso puede generar una señal pequeña. Que el algoritmo la clasifique como contacto ya es otra cosa.

Si el sensor muestra una señal típica de impacto —pico brusco, alta frecuencia, cambio instantáneo de rotación o trayectoria, sincronizado con la posición de la cabeza—, entonces la anulación es defendible aunque en TV no se vea. Las cámaras tienen parallax, motion blur, pocos frames comparado con el sensor, y un contacto mínimo puede ser invisible.

Si el sensor solo muestra una oscilación ínfima y no hay cambio coherente de trayectoria, ni deformación, ni imagen compatible, ni firma de impacto, entonces NO se debe anular un gol. Ahí se estaría convirtiendo una herramienta probabilística en un oráculo.

A Croacia le anularon un empate tardío tras una revisión del VAR polémica vinculada a una detección marginal del balón. Una cosa es una señal clara de impacto; otra es un “blip” diminuto.

Sobre los árbitros: no necesitan ser físicos, pero sí deberían tener formación suficiente en limitaciones de medición, la cual OBVIAMENTE NO TIENEN. Un árbitro moderno que usa sensores, semiautomático, tracking 3D y VAR debería entender conceptos básicos: margen de error, falso positivo, calibración, umbral, sincronización temporal y diferencia entre dato bruto e interpretación algorítmica. Si no, termina pasando esto: la tecnología deja de asistir al arbitraje y empieza a reemplazar el juicio crítico.

En conclusión, no se ve contacto y el único argumento es “el sensor detectó un roce ínfimo” que, como ya mencioné, por el gráfico se puede ver que está mas relacionada a diferencias de presión en el aire al pasar cerca de una cabeza que por un toque con la misma (si la hubiera tocado se vería un pico muy alto y brusco en la imagen).
Se está usando tecnología muy avanzada con árbitros que no la saben comprender (ni el propio VAR). Ningún físico diría que ese gráfico muestra un toque.

En una jugada decisiva, la carga de la prueba debería ser altísima. Sensor sí, fe ciega en el sensor, NO.

[World of Engineering @engineers_feed]

A crystal was just discovered that acts like a metal and a glass at the same time.

Molybdenum oxychloride, announced June 1, 2026.

Metals conduct electricity freely. Electrons move through them like water through a pipe.
Glasses are insulators. Electrons are frozen in place.

These two states have been mutually exclusive for the entire history of materials science.

Until now.

MoOCl₂ has a split personality at the quantum level:
• Along one axis: metallic. Electrons flow freely.
• Along the perpendicular axis: insulating. Electrons don't move at all.

This is called extreme optical anisotropy.

Why it matters:
• Smart contact lenses that can display information without power-hungry screens
• Ultrathin AR glasses that process light differently in different directions
• Photonic circuits that route light the way copper routes electricity

We've had one fundamental state for each material for 200 years of engineering.
Now we have both in one crystal.

Materials science just got a new category.

Chicago lost the Bears this week. A team that's been in the city since 1921.

They didn't lose them to a bigger market or a better deal. The Bears decided they'd rather be a tenant in Indiana than deal with Illinois for one more year.

Think about how badly you have to run a place for that to be the smart move.

They lost them for two reasons.

The people running Illinois would rather villainize a builder than keep one. And they're bad at their jobs.

In 2021 the Bears spent $197M on the old Arlington Park racetrack.

Before they could break ground, Cook County valued the empty lot at $192M (Bears said $60M). They were salivating at the chance to extort a building that didn't even exist yet.

That fight dragged on for years.

The Bears were ready to put $2B into the stadium. All they wanted was a promise the county wouldn't reassess them into oblivion, plus $855M for infrastructure everyone uses. Roads, transit, utilities. A $3B project, two thirds of it private money pouring into Illinois.

Springfield had since 2021 to get this done. They dragged it to the final night of session, passed it through the Senate at 3:39AM, and the House went home without voting.

So now it's all gone.

The funniest part? This started because Cook County tried to grab the tax early. They knew a built stadium would pay $53M a year. Now they get under $4M on a vacant lot. No jobs, no buildout, no new anything.

Congrats on fighting for scraps and losing the whole prize.

Pritzker: they're "an $8.5B valued business" that doesn't need propping up.

But be smart for a second. Almost every NFL city throws in public money for a stadium. Not charity. The return is real. Tourism, hotels, restaurants, jobs, game days, property tax on a huge development. The math works.

Indiana did the math. While Illinois sat on it for years, Indiana passed a bill in months, put up $1B, and took the team.

And the Bears took a worse deal to get there. In Illinois they were going to own their stadium. In Indiana they rent it from the state. A team that wanted to build its own home gave up ownership just to escape Chicago.

Nobody won but Indiana. The Bears lost their stadium. Illinois lost the team, the $2B, and $53M a year in taxes.

Pritzker after they left: "I wasn't willing to give up billions of dollars of taxpayer money to give it to a billionaire-owned family or team."

There it is. "Billionaire-owned."

That's how Democrats talk about any business right before they run it out of town. Call them a billionaire, act like you're saving working families, take a victory lap while the tax base drives across the state line.

Meanwhile they're running the whole state into the ground. And you already know how this ends. You're living in it.

Pensions are $143B in the hole, worst in the country and not close. You pay $6,285 a year in property taxes, double the $2,969 national average, for a city that's $1.15B in the red. The mayor called its finances "the point of no return."

When you run things this badly, you sell what's left.

They leased the parking meters for 75 years to Morgan Stanley and a sovereign wealth fund in Abu Dhabi. Took $1.15B and burned through it in two years. The investors already made it all back, with 58 years left to collect.

Sold the Skyway. Sold the downtown garages. Every asset that made money, gone for one check.

But a fixed property tax rate for a team that's been here 106 years? That's "propping up billionaires."

Companies are leaving. Boeing for Virginia. Caterpillar for Texas. Citadel for Miami. In 2023 alone Illinois lost 56,000 people and $6B in income to other states. The ones who left earned a third more than the ones who moved in.

Indiana didn't outbid anyone. AAA credit, 16 years straight. A $676M surplus. Fourth-lowest debt per person in the country. They just weren't a disaster.

Illinois could have collected $53M a year. It chose zero. Ignore all the bad management but make sure to stick it to those evil, pesky billionaires.

Why must each generation relearn this knowledge?

[Rothmus 🏴 @Rothmus]

As a young socialist, Hayek read Ludwig von Mises’ 1920 paper “Economic Calculation in the Socialist Commonwealth.”

Mises showed that socialist central planning isn’t merely inefficient, it’s impossible.

Without private property and genuine market prices, planners lack any rational way to allocate scarce resources or determine real costs and needs.

Even Oskar Lange, a leading socialist in the calculation debate, effectively conceded the point.
While he promoted “market socialism” with trial-and-error pricing by a central board, real-world socialist planners in Eastern Europe quietly relied on world capitalist market prices as a guide.

Without external free-market price signals, pure socialism would be economically blind and coordination would collapse.

Mises went further, arguing that interventionism, the “middle way” of government meddling, is inherently unstable.
Each intervention creates problems that invite more interventions, eventually leading to full socialization.
Price controls cause shortages, subsidies distort production, and the cycle continues until the economy is fully planned.

The lesson is clear.
Rational economics requires genuine market prices emerging from voluntary exchange and private property.
Half-measures don’t stabilize the system. They accelerate the drift into central planning.

The Austrian School understood this decades before the collapse of the Soviet bloc proved it in practice.

How will they fund this gap?

[Illinois Policy @illinoispolicy]

NEW

Illinois is facing nearly $21 billion in projected budget deficits over the next five years.

According to a new report, state spending will grow by nearly 20%, while revenue is only expected to rise by 11%.

By 2031, Illinois' spending gap will be $5.2 billion.

On page twenty-six of “The Billionaire Tax” proposal in California, it explains how the state legislature can convert from a Billionaire Tax to an Everyone Tax without voter approval.

They can also adjust the tax to be a yearly tax, not just one time…again, without your approval.

Intelligence test for you: if this was meant to just target Billionaires, why did they write this in?

The most important line here isn't about Obsidian or wikis.

It's this: "I thought I had to reach for fancy RAG, but the LLM has been pretty good about auto-maintaining index files."

The entire AI infrastructure industry is building retrieval pipelines. Karpathy just showed that structured markdown with clean summaries outperforms most of them at practical scale.

The real shift: prompting is moving from "ask a question, get an answer" to "architect a knowledge system, let the LLM operate on it."

The prompt becomes the structure, not the query.

His follow-up about spawning teams of LLMs to build ephemeral wikis for every question is where this actually lands. That's not Q&A. That's synthetic research infrastructure spun up on demand.

We've been saying it: the future isn't better models. It's better systems applied to existing models.

Karpathy just described what that looks like at the knowledge layer.

The most "claustrophobic" game ever?

Descent (1995) is a first-person shooter developed by Parallax Software, notable for being the first FPS with fully true 3D graphics and six degrees of freedom movement.

Players pilot the Pyro-GX spaceship through mineshafts on various planets, infected by a virus that has turned mining robots hostile. There you go, the whole story in one sentence!

Movement is the game's hallmark: full six degrees of freedom allows free flight in any direction - forward/backward, left/right (slide/strafe), up/down, and 360° rotation - creating disorienting, stomach-churning zero-gravity combat. For someone like me, being claustrophobic, this was both tough to play yet highly fascinating. I feel Descent is an underrated game that got a bit lost in the shuffle of other great games around the mid 90s.
