I wrote a new piece yesterday, called "Confessions of an Unrepentant Slop Snob", about my escalating rage at AI-generated text. It includes a framework for thinking about when AI involvement is fine -- just another tool -- and when it lands as a violation. charity.wtf/p/confession...

Is your organisation paying observability prices for monitoring outcomes? That's the question at the centre of my upcoming Masterclass on September 2 for engineering leaders. We'll work through five tests to find out whether that's you, using concrete evidence rather than feelings or suspicion.

Does anyone I know work in infosec at IAG or British Airways? I have somehow gained access to someone else's PNR because my email address contact info was put on their reservation, shortly after I updated the email address on my own PNR. I suspect some kind of caching input replay issue.

You will hear of launches and rumors of launches—but here's how to test Gemini 3 yourself. Pick one stubborn document or photo. Run it through our #genealogy research-tuned Gem today (Gemini 2.5). Save everything. When G3 lands, rerun the exact same prompts. If it's real, you'll feel the difference.

Yup. Nothing odd going on here at all. Gah.
Reddit screencap from r/AMA.

I'm a college-educated Black man who drove from Vermont to Florida this summer with my Asian girlfriend. We were pulled over 18 times in 4 days. Ask Me Anything.

After telling a few coworkers about this when I returned to work, one of them (a true Reddit head) suggested I do an AMA. So hi Reddit, nice to meet you.

So I live in New England, work a white-collar job, and fall into what most would call "upper middle class." This past August, I decided to use my summer vacation to visit family in Fort Myers, Florida. Since I'd never done a true long road trip before (my longest drives were maybe 5-7 hours), my girlfriend and I thought it would be fun to make the trip by car instead of flying.

We started in Burlington, Vermont, and made our way down the East Coast. The drive was about 1,500+ miles, and we stretched it over four days. I did roughly 75% of the driving, she took the rest.

Here's the part that baffled me: in just those four days, we were pulled over 18 times. Not for reckless driving or doing anything spicy. Just pulled over, again and again. Each time it was something else.

So I'll give this a shot: Ask me anything.

It’s been a dirty word in the US for decades. As far back as McCarthy, if not farther. What hurts my head the most is the conflation of socialism and communism. The right equates nationalized healthcare with Soviet Russia. It’s ridiculous, but so many people don’t know better.
