If you would like for me to come to your conference or convening and give a 45-minute rant about what makes good digital privacy trainings and guides, particularly for high-risk populations, hit me up.

Yes. #coffee

Also, what a freaking pain in the behind the @bsky.app post character limit is. Geez, I hope this platform dies so we can all finally move to Mastodon. Even LinkedIN gets this right.

This should change the technical planning decisions of every forward-thinking company in AWS as well. Before this, you could assume services in preview would eventually make it to GA and plan your product development accordingly. Not anymore.

A bit shocking to think AWS would make the investment to build something, make it available to customers, and create an expectation of this being promoted to supported feature *before* they had thought through the business reasoning behind it.

In over 10 years of building on AWS this is the first time I've seen them discontinue a service or feature that was in preview.

Just got this e-mail from #AWS:

"Thank you for your participation in the preview of our Firehose CDC solution. (...) After careful consideration, we have decided not to proceed with general availability of this feature due to business reasons."

Weak password allowed hackers to sink a 158-year-old company Transport company KNP forced to shut down after international hacker gangs target thousands of UK businesses.

A sobering read and reminder that #cyber attacks and #ransomware attacks in particular can have devastating real world effects. A 150+ Yr old company out of business because of an easily guessable password. It could happen to any of our organisations. #WeakestLink www.bbc.co.uk/news/article...

'I'm being paid to fix issues caused by AI' Businesses that rush to use AI to write content or computer code, often have to pay humans to fix it.

That this even needs to be said is further evidence that we are in the worst possible timeline. 😢

CVE-2025-6543 (citrix 🩸) hit KEV. that means confirmed exploitation with receipts. will wash dishes for payloads. bob [@] greynoise [.] io (some mastodon clients really bork email addresses) if you have'm.

Is AI a con? A new book punctures the hype and proposes some ways to resist AI slop means faster and cheaper content, and the technical and financial logic of online platforms creates a race to the bottom.

A prolific hacking group that's shutdown retailers and insurance companies turns to aviation A cyberattack on WestJet last week is likely tied to the Scattered Spider gang, a source tells Axios.

Mandiant is now aware of multiple incidents in the airline sector that resemble Scattered Spider. The industry should button up its call centers where this actor has had a lot of success with social engineering. www.axios.com/2025/06/27/a...

I am so grateful we saved a few million bucks by DOGEing the Voice of America's Farsi service. There's no possible value in having a way to send the Iranian people a message.

Oh, wait, maybe it was incredibly stupid and shortsighted. Yeah, I'm going with that. DOGEy, even.

Understanding the Power and Limits of Generative AI If you read the copius material made available online by experts (real or otherwise) and executives of companies deeply invested in generative AI, you could be forgiven for thinking we are a step away...

I wrote a LinkedIN article targeted at executives trying to convey that very message. www.linkedin.com/pulse/unders...

I suspect that fact that the vast majority of LLM users don’t seem to have received this (really very simple!) message is because the AI companies have a vested interest in us not understanding it. “ChatGPT is smart, it just makes mistakes sometimes” is much more marketable than the truth.
