(Infowars now beong owned by The Onion is a really cool story and I'm glad things like this also happen in 2026.)

Not trying to brag, but I was an avid Infowars reader long before it became cool.

Oh wait. No, no I wasn't.

I was checking Wikipedia to see how bad M.I.A. (whose music I kinda like) really is these days and she is "announced her anti-5G clothes line on Alex Jones's show" bad.

Humanoid robots race past humans in Beijing half-marathon, showing rapid advances Dozens of Chinese-made humanoid robots showed off their fast-improving athleticism and autonomous navigation skills as they whizzed past ​human runners in a half-marathon race in Beijing on Sunday, hi...

Sure, a robot can run a half marathon faster than humans, but can it run the half marathon in well over two hours, poorly trained while forgetting to drink enough water? That's when I'll get worried about robots taking over my hobby www.reuters.com/sports/human...

I suddenly remembered that five years ago, @lodrina.bsky.social and I gave a Black Hat talk with 'trauma' in the title. I still think that was really cool.

Hey. That's my To Read list.

Under John Paul II, who was considered arch-conservative, it was popular among Dutch Catholics to say that you were Catholic but disagreed with the Pope. (The Catholic student pastor at my university was openly gay, to give you the picture.) So there is some kind of precedent to vanceplaining.

(S+) Polizist auf der Flucht: Vor Schloss Neuschwanstein setzte er sich ab, nun enthüllt dieser Mann Chinas Verbrechen Er verfolgte Uiguren und brachte sie in Foltergefängnisse. Dann floh der Polizist Zhang Yabo aus der Volksrepublik nach Deutschland – und liefert seltene Einblicke in Chinas Repressionsapparat.

A fascinating read by my colleagues on a police officer who was part of the detention system in Xinjian and now has fled the country and now is speaking out, because if one day, he was asked, what he did to fight the injustice, he can say: "I spoke the truth"

Her daughter was killed by gunfire in Gaza school. For her and others, 6-month Israeli ceasefire isn't working | CBC News Tent schools like the one where nine-year-old Ritaj Rihan was killed by gunfire this week are symbolic of the fragile hope Palestinians have for the future and the paralyzing fear they still live with...

Everything in this CBC article on the 'ceasefire' in Gaza that very much isn't a ceasefire is important to read, so I just say here name: Ritaj Rihan. 9 years old. Killed by Israeli forces in front of her classmates www.cbc.ca/news/world/g...

This is a good and slightly scary article written by an expert, on whether traditional cryptography algorithms will soon be broken by quantum computers. TL;DR: it is likely enough to really care.
(ECDH, which I once had fun explaining in conference talks, is now considered a "legacy algorithm".)

When an AI tool recommends an action and an employee carries it out, audit logs capture a legitimate human decision. The AI's role disappears. Addressing that blind spot takes more than awareness training. https://zeltser.com/ai-influence-awareness-training

FBI Extracts Suspect’s Deleted Signal Messages Saved in iPhone Notification Database The case was the first time authorities charged people for alleged “Antifa” activities after President Trump designated the umbrella term a terrorist organization.

Signal has a setting to stop this (Settings > Notifications > Notification Content). It's likely not an issue limited to just Signal, but more fundamental friction between secure chat apps and phones. Very interesting data point when talking about forensics www.404media.co/fbi-extracts...

New from 404 Media: the FBI was able to extract incoming Signal messages from a phone even though the app was deleted. Why? Because parts of messages were stored in the iPhone's internal notification database. Shows how secure chat data can come from unexpected places www.404media.co/fbi-extracts...

martijnreadsbooks on Instagram: "Stephen Fry - MythosI didn't grow up reading Greek mythology and so my knowledge has always been patchy. I wanted to fill the gaps,…" Stephen Fry - MythosI didn't grow up reading Greek mythology and so my knowledge has always been patchy. I wanted to fill the gaps, if only to help me better understand the many references in art and literature. Fry's humourous retelling did a great job at that.

Yeah, that has an awkward typo. Teaches me to proofread better.

Anyway, I decided to use this place for musings about books I read, including books I read long ago that I feel like saying something about.

Cross-posting these on Instagram, if that is your thing www.instagram.com/martijnreads...
