One thing that's changed a LOT in the past ten years: gift guides used to be about a writer or editor picking things they thought were cool and that their readers would like. Now it's all about monetizing the clicks, and it's so, so dullllllll

AND supporting your local library is super important! If you actually DO want books to be available to everyone, the library *already exists* and is staffed by the people who are deep in the trenches of fighting censorship! Supporting the library is doing actual good for your community!

Just saw someone claim that authors who want to be paid for their work are "class traitors" because we "only let the wealthy" read our books, and I think I need to go into the woods to scream into the night for a bit.

Free transit idea for @zohrankmamdani.bsky.social that’s easier, cheaper to implement, has fewer weird what-ifs, and doesn’t involve the state:
Buy management control of Citibike, expand it citywide (finally), and make that fare-free for residents.

I designed the artwork to capture the moment when multiple colorful light beams strike a single-layer material. The glowing waves rising from the surface represent the newly generated twisted light 💡

The merkaba has long been a mystic symbol. At its heart is the intersection of two tetrahedra. Here is my take on this classic form, replacing the sharp lines by soft curves.

I snatched this chart from @valent10francois. We see the social spending in France by age. Cutting entitlements? Usually reference is made about the orange slice (unemployment) or the green slice (family benefits). The blue retirement spending mustn’t be touched.
