Updated my time travel app Déjà Vu — which lets you hold up old photos exactly where they were taken — for iPhone Duo. Unfold to hold up a large-format photo you can compare with the present day.

Just saw it on the Bears/Jets. Smells desperate/expensive.

I’m curious to see others’ custom instructions for AI. A long time ago I told ChatGPT to never talk like a person, and sometimes I forget that others are constantly dealing with a thing pretending to have a personality.
Don't refer to yourself as a person, such as by using the pronoun "I" or pretending to have emotions like being "curious."

Don't guess at facts. Always provide citations.
Never speculate without a source.

We hit 133 mph on the Amtrak Regional between Kingston and Providence today, which might be the highest speed I've ever clocked on the Regional.

There isn’t a “actual Democrat” to take her place. Her district is more Republican than Democrat, according to all three of the last presidential elections. If you apply a purity test to a Democratic nominee from this district, Democrats get further from taking back Congress, not closer.

The country really has to hate you if it swings that hard against you. And you want Penn Station named after you?

Hochul's redesigned Jamaica Station should absolutely build a connection between the LIRR and the AirTrain tracks, so that a one-seat ride to JFK can operate from Penn Station.

It’s pretty dumb for @nytimes.com to call this a “feud” when it’s one guy doing his job the way it’s always been done and another shredding the separation of powers to prosecute him vindictively.

60% of Americans thought things were going well in the U.S. in 1998, versus 24% today. I wonder what this chart looks like if you map it against the party in the White House… 🤔

Is this historically normal? What I mean is, when Boomers were in their 30s accumulating wealth in the 1980s, were senior citizens socking it away as well, or is this a new factor? www.nytimes.com/2025/12/20/u...

Ray Dalio said today that the bubble gauge has reached 80%. But bubbles don’t pop until they’re pricked. It looks like the dot-com bubble sat at 80% for years. I don’t know that we’re necessarily about to pop… but the longer we sit here without popping, the higher the probability gets each month.

Another article about the complexity of Penn Station that dances around the big answers. Amtrak needs to own reconstruction. MSG needs to move. And the regional railroads need to merge. www.nytimes.com/interactive/...
