People who think mass deportations are a housing affordability strategy have no place in the YIMBY movement.
A reminder, a person who claims to be a YIMBY but backs the deportation of people to "solve" the housing crisis is just a NIMBY.

This is so cool: Copper, which makes induction stoves with li-ion batteries integrated, is going to build *10,000* of these suckers for use in New York public housing.
Better cooking, easier cleaning, grid resiliency built in. Win win win.

Important and gutting series from the Times:
People always are shocked to hear that LA represents the second highest transit ridership in the US!
One more thing. When I wrote about this study showing one-third of Americans don't drive, people were messaging me saying this cannot be true for LA.
In LA County *23 percent* of the population is under 16. Kids are people! We must plan for their movement, just like all nondrivers. Hope that helps!

Highly recommend diving into NRDC's study on car access, which @keawilson.bsky.social wrote about here: usa.streetsblog.org/2025/10/02/report-16-million-have-no-car-access-at-all
Where Nadir was killed, 14% of LA households are car-free. But the infrastructure does not match that reality

Get you a mayor that gushes about grade-separated bike lanes when traveling the world!
I like these sidewalk-level bike lanes that also have separation from pedestrian space on the sidewalk with pretty materials like cobblestone and/or trees.

Solar’s price drop is astonishing: panels are now 98% cheaper than when I first analyzed them in 2004.
Today, building a fence with solar can be cheaper than using wood.
