Kyle Kingsbury is not a journalist. He is not an op-ed writer.

He is a computer safety researcher.

And he has written one of the most compelling, comprehensive accounts of the ongoing hell in Chicago that you could possibly imagine.

In under 1600 words.

I Want You to Understand Chicago Politics Chicago 2025-11-08 I want you to understand what it is like to live in Chicago during this time. Every day my phone buzzes. It is a neighborhood group: four people were kidnapped at the corner drugstore. A friend a mile away sends a Slack message: she was at the scene when masked men assaulted and abducted two people on the street. A plumber working on my pipes is distraught, and I find out that two of his employees were kidnapped that morning. A week later it happens again. An email arrives. Agents with guns have chased a teacher into the school where she works. They did not have a warrant. They dragged her away, ignoring her and her colleagues’ pleas to show proof of her documentation. That evening I stand a few feet from the parents of Rayito de Sol and listen to them describe, with anguish, how good Ms. Diana was to their children. What it is like to have strangers with guns traumatize your kids. For a teacher to hide a three-year-old child for fear they might be killed. How their relatives will no longer leave the house. I hear the pain and fury in their voices, and I wonder who will be next. Understand what it is to pray in Chicago. On September 19th, Reverend David Black, lead pastor at First Presbyterian Church of Chicago, was praying outside the ICE detention center in Broadview when a DHS agent shot him in the head with pepper balls. Pepper balls are never supposed to be fired at the head because they can seriously injure, or even kill. “We could hear them laughing as they were shooting us from the roof,” Black recalled. He is not the only member of the clergy ICE has assaulted. Methodist pastor Hannah Kardon was violently arrested on October 17th, and Baptist pastor Michael Woolf was shot with pepper balls on November 1st. Understand what it is to sleep in Chicago. On the night of September 30th, federal agents rappelled from a Black Hawk helicopter to execute a raid on an apartment building on the South Sho…

La Cour pénale internationale va remplacer l'ensemble de ses outils numériques Microsoft par un logiciel européen (OpenDesk).

Et ce, pour éviter de subir de nouvelles sanctions américaines.

Bonne idée...

L'indépendance numérique devrait être une priorité pour toutes les institutions européennes.

Competitor enters a major AI competition (RNA folding)
GPU poor so can't train an AI
Builds a "classic" eng pipeline instead. (90s tech)
Wins and beat everyone using DL 💀
Their winning "hybrid" model had an AI in it. Their original one did not and had a higher score
So they won despite the AI 😂

While many teams relied on deep learning, the winning team (jaejohn) surprised everyone with a highly optimized pipeline that revived classic template-based modeling. 👇

L'État, à la base, ce n'est pas juste d'être une immense tirelire qui collecte des impôts et reverse des subventions aux entreprises et des allocations aux ménages.

Sa fonction première c'est d'assurer la production de services non marchands de qualité.

In 2016 Hinton predicted that AI would replace all radiologists in five years. Ten years later, why hasn't it happened? This post is a great explainer.

AI isn't replacing radiologists
Radiology combines digital images, clear benchmarks, and repeatable tasks. But demand for human radiologists is at an all-time high.

skrub DataOps help you construct complex and extensive hyperparameter search spaces. However, interpreting results from large grids can be challenging.
To address this, skrub generates a parallel coordinate plot that visualizes all runs and the parameters used to achieve specific results.
