Recall Is a Write

The message that ends about one session a week. Everything above this line is gone.

A model can read a memory without changing it. You can’t. That difference, and not the size of the window, is where I’d look for what makes a person creative.

The Computer Brings It Up First

This morning's brief, top of page one. Nobody asked for it.

I stopped asking my computer questions. It tells me what it thinks I need to know, and the hard part turned out to be deciding what counts.

Software for a Six-Day Trip

Six days of software: the login page for our Thanksgiving trip app.

I talked to my computer about a vacation and ten minutes later we had an app for it. Here is why that matters more than it sounds.

Models Will Be Commodities

Terminal chat: a weather question routed to a local tool, then a fun fact answered by a local 35B model
Local-first: a weather lookup and a fun fact, answered on the machine.

Most of what people ask a model is about to run on hardware they already own. Here is what I think that changes.

RAGBRAI Postscript 2: Clean Slate

St. Louis Canyon. The kids remembered the sandstone.

The last day at Starved Rock, and the last post of the series: a planning day with tea and the Full Focus Planner, St. Louis Canyon with kids who’ve outgrown the trail, grandparents at the lodge, and the yearly ritual of wiping the slate clean before the drive home to Virginia.

RAGBRAI Day 7: The Finale

The MLB stadium at the Field of Dreams, in the mist, full of bike helmets.

Day thirteen of the RAGBRAI log: the last 34 miles into Dubuque — a misty solo roll to the start, batting practice at the Field of Dreams, one final Beekman’s rescue by Jeremy’s ears, the Mississippi, and then Field of Dreams again that night with the kids at Starved Rock.

RAGBRAI Day 6: The Girls’ First RAGBRAI

Camp outside Dyersville: eight miles from town, zero bars of cell service, one Starlink.

Day twelve of the RAGBRAI log: both girls ride their first RAGBRAI — Elizabeth to the meeting town, Maura to the finish — plus Iowa’s smallest cow, a regrettable Red Bull, a soft landing in a ditch, and a derailleur that didn’t survive the gravel.

RAGBRAI Day 5: Century Day

Jesup, the last pass-through town, holding it down with the Iowa Pork tent and a sky-dancer.

Day eleven of the RAGBRAI log: 102 miles on a written game plan and a cranky knee — two Casey’s stops, a perfect pace line, Beekman’s at mile 55, the century patch, and a finish over the Wapsipinicon into Independence.
