We Still Don’t Know if Robotaxis Are Safer Than Human Drivers And even if self-driving technology proves to be less dangerous, there are many better ways to improve traffic safety and prevent fatal crashes.

Much has been written about potential safety benefits of AVs. Given the lack of AV data transparency, I cannot speak to whether, or to what degree, AVs are safer than an average human driver. What I can say:

This is the wrong question.

Here’s How the AI Crash Happens The U.S. is becoming an Nvidia-state.

So my daughter is back from Cambridge just for Sunday lunch. She wants a proper roast dinner with roast spuds and Yorkshires. Takes a bit of work on the timing but no problem, we will have a lovely chill time.

I thought. /1

An unlikely couple, a doomed affair and their €64mn ransomware scam How a mysterious tip-off led investigators to uncover the inner workings of a highly unusual hacking operation

In Sirotin’s case, the fatal mistake came in the form of two online purchases β€” a knife, bought with the same email address used to rent the suspicious servers discovered by investigators, and a pair of plane tickets he had bought for his parents

Intune now has dedicated security recommendations docs just like Entra πŸ”₯

The Entra security docs are extremely popular, and I love seeing other teams publishing this kind of guidance

Thanks to my collegaue (Josh Gatewood) for pointing this out!

Pluralistic: The real (economic) AI apocalypse is nigh (27 Sep 2025) – Pluralistic: Daily links from Cory Doctorow

The real (economic) AI apocalypse is nigh

"So, you're saying a third of the stock market is tied up in seven AI companies that have no way to become profitable and that this is a bubble that's going to burst and take the whole economy with it?"

Giant increases in capex from Big four tech

Giant increases in capex from Big four tech

Staggering chart from the FT. Each of Alphabet, Amazon, Microsoft and Meta (MAMA!) are set to spend over $100bn annually on capex by 2030, more than all four combined in 2020. All because of the LLM-triggered AI boom...

User-Defined Permissions Sensitivity labels Support in SPO Finally, Microsoft solved the technical issues that blocked SharePoint Online support for sensitivity labels with user-defined permissions. The feature is GA.

After much delay, #SharePoint Online finally supports sensitivity labels with user-defined permissions. Might not sound important, but it opens up support for DLP, eDiscovery, and more.

"For the cover art of my debut novel, I envisioned a foggy background with two shadowy figures grasping for each other but remaining barely out of reach. Instead, the publisher insisted on a pink background with an illustration of a baby giraffe next to a Ferris wheel."

Worth a watch:

Head of Signal, Meredith Whittaker, on so-called "agentic AI" and the difference between how it's described in the marketing and what access and control it would actually require to work as advertised.

I have not paid a ton of attention to the uproar over RTO policies, bc we are all in on distributed teams and not going back.

My impression (via social media) has been that these were shadow layoffs.

Last month I asked an investor why they are doing RTO. He said: "Retention, mostly. And morale."

Also applies to off-shore teams. Works much better if you’ve met face to face and gone out socialising even if it’s a one off trip. It’s particularly important for getting more junior team members to speak up early when they don’t think something is going to work.

Look at him. Absolutely irresistible.

If you don’t know if people put creds in the phishing site then it’s not a bad response, they might also have wanted to reset credentials and this gave them an excuse (maybe they’d increased min strength since some of the passwords were set)

β€œunusual e-mail activity” I’d assume they think people got in and are sending spam /phishing from those accounts but don’t know howmany accounts got popped. Most schools can’t use MFA (no phones allowed) and need to allow BYOD (view home work at home ) so it’s hard to lockdown.

Trump Officials Blame Mistake for Setting Off Confrontation With Harvard (Gift Article) An official on the administration’s antisemitism task force told the university that a letter of demands had been sent without authorization.

I read this as: Harvard was planning to capitulate, then the Trump Administration accidentally sent the letter they meant to save until after Harvard capitulated on the first round of demands. www.nytimes.com/2025/04/18/b...

So much of cybersecurity is "We must secure the Orphan Crushing Machine so that unauthorized people do not crush the orphans," and not "Why the fuck are you building an Orphan Crushing Machine in the first place?"
