My job is assembly, so today I am learning about braided fishing wire and how to tie fishing nets. Hoping to incorporate a strong net grid into the project. It's going to weigh about 15-20 pounds!

Check out my new blog post on a prototype shelf that I designed and made out of cardboard based on the "squaring the square" problem, which asks if you can partition a square into smaller squares all of different sizes. (You can!)
Come for the photos, stay for the 3D model!

NOW UPDATED: @meganpiont.bsky.social's "How to report ICE" zine includes the ✨new ICE hotline number for NYC✨
For those new to this type of guide: "SALUTE" is an acronym to help us remember what steps to take.

This feels like another bad downstream consequence of the MTA barely expanding the subway in the last eighty years. The expectation should be that everywhere in NYC is either near a subway already or that it will be soon!

Our new piece on the importance of transit connectivity in Boston #mapoli - it's long past time to connect the Red and Blue Lines. commonwealthbeacon.org/opinion/the-...
The Red-Blue Connector: A half-mile of subway that benefits an entire region - CommonWealth Beacon
It’s easy to look at the short length of the proposed Red-Blue Connector – less than half a mile – and mistake it for a project with small impact. Nothing could be further from the truth.

So “inclusion” is reduced to representation: a few new examples or texts, while the deeper question - who decides what counts as knowledge - is never asked.

What Zohran Mamdani Teaches Us About the Moral City
His mayoral campaign challenged one of America’s oldest habits: mistaking inequality for inevitability.

This is really what it’s all about. They’re not upset about socialism or whatever. They’re upset that Mamdani represents an upending of traditional influence and city politics. He won’t take their calls because he cares more about people who traditionally can’t get the mayor on the phone.
Canadian multimillionaire and Shark Tank guy Kevin O'Leary went on TV to say he's upset Zohran won't talk to him: "I and others who invest in real estate have tried to get a meeting to figure out what's rhetoric and what's policy. So far for me it's been crickets."

One thing the mayor-elect could do between now and January 1 is to call on Kathy Hochul to veto the bill on her desk that would ban one-person train operations in the NYC subway. Mamdani was absent the day of the vote, and banning OPTO is incompatible with lower cost (or free) transit.

Unsolicited writing advice, no. 4: There’s nothing wrong with writing fluff. Fluff insulates. It protects. It cocoons us from a world filled with sharp edges and sudden fires. It makes a warm bed to sleep on; builds soft ramparts; saves lives.
