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…

That’s disappointing. I was really looking forward to it being in LA instead *sigh*

I have a friend looking to apply to a role at x.company (the Alphabet/Google subsidiary not the Musk company). Do I know anyone working there that could help them out by referring them?

I'll share their details privately and ultimately leave the choice to refer up to you.

While the feds continue to play stupid games, SNAP recipients are set to lose food aid for the next month. In the Bay Area, a growing number of restaurants are stepping up to help, and we're maintaining the list. Share with anyone who needs it. www.coyotemedia.org/these-bay-ar...
These Bay Area Restaurants Are Offering Free Food to SNAP Recipients
Amid a government shutdown that will cut off aid for 42 million Americans, local food scene folks plan to pick up the slack.

After all these years, this was the first time I've been to Raleigh. I managed to avoid HQ the entire time that I worked at Red Hat. I guess I shouldn't have been that surprised when I recognized Davie St and lo and behold there it was.

We were in the peninsula yesterday, so we stopped by the Great Glass Pumpkin Patch 🎃 in Palo Alto yesterday! It was a local charity event by the public library and a glass blowing studio in SJC.
A collection of glass pumpkins in front of a tree each a shade of orange with a green stem. A shelf setup with a variety of glass objects: some pumpkins with witches hats, apples, ghosts, and notably a bat hanging from chains.

This book (Code Health Guardian by Artie Shevchenko) came recommended by an experienced software engineer as a great read.

Starting it now. On first glance, it looks like a promising one, going back to software engineering basics that start to become more important with GenAI

Unless I'm reading this badly wrong and the administration puts out contrary implementation, it would appear that starting tonight, anyone with an H-1B who doesn't write a $100,000 check to the US government is banned from reentering the country if they're currently outside the US.
