PSA: The Amazon wishlist doxing threat is much greater and more immediate than folks might realize. Attack works like this:

Stalker who wants your address opens an Amazon seller account and lists themselves as a third party seller for any item on your public wishlist. Then, they order the item […]

What is happening in the United States is horrible. Half the Americans is in the right side, and it is the side that can restore and make the country sane again. Act now (without getting killed), do what you can to fix this mess. Get back your country.

Bloomberg's X account has more than 800k followers. Their most recent post was shared five times

It would basically come at close to zero cost for outlets like Bloomberg to delete their X accounts, and "We don't want to use a non-consensual deepfake abuse app as a comms platform" is a fine excuse

I hope the Danes and the other European forces are training in guerrilla warfare as that always works against the USA, especially on hostile territory (cf. Greenland).

The European Cloud Situation at the end of 2025 - Bert Hubert As the year draws to an end now is a good time to review where we are with Europe’s cloud situation, and what has been achieved. One thing is certain, a lot has happened, and also quite a lot has beco...

So, what did we achieve for 🇪🇺's cloud situation in 2025? It is now crystal clear our governments can't continue to run on 🇺🇸 clouds. Yet even now, neither buyers or sellers of cloud tech in 🇪🇺 sense the urgency. Below I elaborate & discuss an unorthodox way out of this mess: berthub.eu/articles/pos...

We still need to get from a situation where Russia pretends to negotiate to a situation where they need to negotiate.

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…

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.

How My Reporting on the Columbia Protests Led to My Deportation As an Australian who wrote about the demonstrations while on campus, I gave my phone a superficial clean before flying to the U.S. I underestimated what I was up against.

It's important for Europeans, and others from visa-waiver countries, to understand they don't have freedom of speech rights when visiting the United States.

The Trump regime is still deporting visitors for critical comments made online, because they can.

Day to day: the user experience of getting a direct answer for simple things compared to scrolling a bloated blog post, with ads and cookie banners. It would be better to solve the state of the web but hey, it's a workaround.
