There is a particular sound a fraud model makes right before someone silences it. Not an alarm, not a siren — a score. A number ticking upward on a screen, quietly, the way a fever climbs before anyone thinks to take the temperature. At Visa, in the years when the network was still teaching itself […]

Imagine standing on California Street in the 1960s, where two San Franciscos were being shaped just a hundred yards apart — one in a hotel, the other in a former annex.

A walk through two versions of the same season, and a question about whether the old shape was ever really the problem.

We were the last class in a room full of forty years of Jay’s vision, and he taught us how to survive being seen—light, gesture, color, and open joy.

I’ve built a prompt that turns ChatGPT into a personal AI research analyst—helping me cut through the noise and find what’s truly new in the field.

The author sought Gemini's assistance to create a prompt for accessing AI-related YouTube videos that are engaging and informative. The prompt targets retired tech professionals, focusing on high technical substance and recent uploads. Strict guidelines exclude clickbait and novice content, ensuring videos are intellectually stimulating and well-produced.

A day or two ago I reminisced about San Francisco’s KKSF which was a delightful listen during the late 80’s-early 90’s. While I was working on that post, it dawned on me that I could try using AI to write a prompt to use with a new feature in Apple Music that allows you to […]

The magic isn’t in the walk itself—it’s in how it shifts your focus so old memories, half-formed ideas, and forgotten details start talking to each other.

The trucks are what I remember. Not the houses, not yet — the trucks. This was 2012, Atherton, a Tuesday probably, and I was driving through on some errand that doesn’t matter anymore. What matters is that the street had rearranged itself. Contractors’ pickups lined both shoulders, nose to tail, so many of them that […]

Before streaming, before the algorithm chose for you, a San Francisco radio station chose for you instead in such a delightful way.

As intelligence gets cheaper and more interchangeable, the economic prize may be migrating somewhere else entirely — to whoever controls the harness around the model, not whoever trained it.

In the spring of 2026, Nvidia reported a quarter in which it sold $81.6 billion worth of chips, wrote it up at a gross margin of nearly 75 percent, and casually mentioned that cloud GPUs were sold out. Jensen Huang called it the largest infrastructure expansion in human history, and for once a CEO’s hyperbole […]

The appetite for manufactured stakes — built over decades in fraud detection, flying, and trading — doesn’t retire when the career does.

The race that matters may not be the sprint toward the next frontier model — it may be the slower, unglamorous work of teaching ordinary engineers to put the technology to work.

The lifeguard came out with a canvas bag, and that was the signal. Saturday morning, Kettering, Ohio, the municipal pool not yet warmed by the day, and forty kids arranging themselves along the edge like something had been rehearsed, though nobody had rehearsed it. We knew the shape of the thing without being told. He […]

SpaceX’s plan flips the script—rooftops become cell sites, and customers pay SpaceX instead of landlords, cutting costs big time.
