Feel like we’re almost at the part of the movie with the big reveal- the name of the “human” warning about civilization-ending AI is actually “Dario, a model.”

My kid’s sleepaway camp has a service where they’ll print emails and deliver them like regular mail so they get messages sooner. But it’s text only and kid wanted pictures of the dog. Solution? ASCII art! (Yes I just posted a picture of text art of a picture) @darthbluesky.bsky.social

They excluded Arizona and other places that don’t currently change their clocks, but I like how the “No data” label instead implies that we just can’t predict when the sun will rise in these places.
NYT headline and summary 
Should We Make Daylight Saving
Time Permanent? More light at the day's end comes at a price: much
later winter sunrises across much of the U.S. Scientists have documented consequences for health and the economy.

The map shows the US in various shades of blue indicating how many months each year will have sunrise after 7am under the proposed policy. Arizona and a smattering of counties around the country are in light grey which the map key indicates is “no data”.

New bike lanes painted on Broadway in Cambridge overnight last night, part of section B plan. Maybe those cars were already there and painted around, but the signage already said no stopping- hopefully some physical barriers coming.

Curious what’s going in the super reinforced steel core of the new building in Kendall Sq
Steel frame of the first few floors of a building under construction in Kendall Sq. The external girders are a typical density but there is a core of very tightly packed steel beams and large steel plates on either end.

My pet peeve- regulators making a big deal about 1 vs 2. Throttle-only is not fast! My 750W bike using just throttle does 0 to 19 in 13 seconds. The real benefit is startup boost at traffic lights and low speed maneuvering. Most people writing anti-ebike articles have never ridden in city traffic.

I tried to make some baguettes but messed up the timing so they were too dense, but they magically ended up the same texture and flavor as Bertucci’s rolls.

Looking for problem solving: Air France abandoned our bag in CDG airport, never loaded it. It has an AirTag and looks like it’s been sitting at the baggage counters for two days. We filed a claim and sent them the AirTag link but they won’t take the five minutes to track it down and ship it. 1/2

While biking past Bowdoin saw a dollar bill lying in road at a red light and looked all around as I picked it up because I figured it must be an economics experiment or some transportation study about bikers stopping at red lights. Driver in the car next to me gave a thumbs up.

Don’t forget that Republican governments have previously argued that using “view source” on a public website is a crime. arstechnica.com/tech-policy/... www.nytimes.com/2025/03/13/u...
This time, it did not include those details. A White House official said that was done for security purposes.
The result was that the group's new claims appeared impossible to check.
The New York Times, at first, found a way around the group's obfuscation. That is because Mr. Musk's group had briefly embedded the federal identification numbers of these grants in the publicly available source code. The Times used those numbers to match DOGE's claims with reality, and to discover that they contained the same kind of errors that it had made in the past.
Mr. Musk's group later removed those identifiers from the code, and posted more batches of claims that could not be verified at all.
That shift was a major step back from one of Mr. Musk's core promises about his group: that it would be "maximally transparent."

A brand new type of travel hell at Logan: airline gives you meal vouchers for a canceled flight, but when you try to redeem it restaurants tell you they only take card and don’t have a cashier to redeem. So kids bought $60 of candy and soda at the only place that would accept it, a snack kiosk.
