Solidarity with the Jewish community, because I feel this every time I see a pride flag in my very Conservative town I live in. Minorities exist and we will continue to exist, and we need to stand together against the bigots who want us gone.
I wish all who celebrate a Happy Hanukkah. 🕎

Annual reminder that if you see a menorah in someone’s window, that’s an act of defiance against bigotry and hate. It’s also pride and bravery.

It’s says “a Jew lives here” and that’s both painting a target but also reminding everyone that we still exist and we always will.

Honestly, it is always an honor to talk with @dahlialithwick.bsky.social on her show Amicus. She is so perceptive, brilliant, and curious all at once.

Here we are trying to g to make sense of another year, and ringing alarms early for the upcoming year.

Love reading this 1946 review of the original. "Hey maybe we should all learn from Nazi Germany's educational purges and be ready to defend higher education against the many adversaries that fascists might array against it".

Preposterous! Alarmist! Could never happen!

This is one of the weirdest things when people are quoting Shakespeare. Practically every line Shakespeare ever wrote is being said by a character who has his own motivations, context, meaning. the lines by themselves are like saying lama sabachthani without, you know, the Cross

Everybody talks about wanting to change things and help and fix, but ultimately all you can do is fix yourself. And that's a lot. Because if you can fix yourself, it has a ripple effect.

With this piece of bread on the ground in Ottawa, Canada and the one below in Perth, Australia, @drstip.bsky.social and I have successfully created an Earth sandwich.

The hot dog vs sandwich debate is concluded.

If the Earth is sandwiched, everything is a sandwich.

HAPPY EARTH SANDWICH DAY!

I’m just going to tell the story. Back in 2000 I was volunteering for the Gore campaign when he came along with Julia Louis-Dreyfus, Alfre Woodard and Dule Hill to a GOTV event here in MN. He ended up sitting down across from me stuffing his envelopes.

Birthright citizenship under the common law, a thread:

I have done this many times on social media, in print, and in media interviews, but not to be accused of taking others’ not seriously enough, by plainly stating the law and history of birthright citizenship, I’m taking the time here:

Any embedding of K_7 in 3D has a knotted Hamiltonian circuit (red below).

#mathgame idea (inspired by terrytao.wordpress.com/2025/12/08/t...)

Shuffle. Deal each player a face down stack of 10 cards. You flip over a card, which you can keep or discard. Each subsequent card you keep has to be >= last card you took. Winner is player with the largest sum. A=1, K=13.

Counting up the work I've done this year, and feeling pretty good about it! In 2025, I've drawn:

146 maps
17 figures
4 pieces of commissioned artwork
Fantasy subway maps
c. 50k words worth of patreon writing
Lots of non-commissioned artwork

That's a lot to draw by hand! Here are some favorites:
Map of the globe, with Europe in the center. The map mostly does not show Oceania. The map is colored to look like an old-timey parchment maps. There are 15 drawings of various cultural artifacts on the map, each inside a black circle with an arrow pointing to the artifact's location in the world. A map title, written on what looks like torn parchment, reads, "Some Places and Treasures, Section 3: 1300 - 1500" There is a red dragon in the water. I've shown him before, so I'll share his alt-text again: A red sea serpent with little wings or fins. He might be a stupid dragon. His long, long tail curves several times before vanishing into the water behind him. You can't tell where in the world we are, as there are no landmarks. The serprent's tongue is yellow, like he's just popped a banana slug into his mouth. His expression kinda looks that way, too. His eyes are wide and his maw is open in something that looks like surprise. Like someone just pinched his butt in the middle of his quarterly earnings presentation. His name is Speril, and he is an only child. Greyscale drawing of a floor plan of what looks like the first floor of a house, with ten rooms and a flight of stairs. The title at the bottom reads: "The Magic Bookshop." There are two exterior doors: a front door and a back door. The floor plan is on a tattered piece of paper that looks as if it is being unrolled from the top, so there is a curl of paper, or a scroll, at the bottom. Around the floor plan are four animals. A cat, labeled Angel, is resting on top of floor plan, dangling a paw down. To her left is a huntsman spider named Drusilla. At the bottom of the page on the left is a golden retriever named Willow, sitting behind the scroll like a good boy. On the right side is a cat named Spike, who is sitting on top of the scroll and crushing it like an jerk. Typical dog and cat stuff. There are four piles of books around the outside of the floor plan: two large, and two small From top left down in a switchback pattern, the rooms are labeled: Yellow: Books with gold covers Possibility: Mystery, Crime (where they do the spell) Exeunt Omnes: Older books (where Kennedy finds the magic book) The Office (where hazel makes tea) Bathroom Gurgler: Sci-fi, Fantasy (where Hazel goes to hide out) The Scriptorium: More modern books (where Hazel sends Luke to find a book for his niece) Taboo The Fishbowl: Romance (where Luke makes a pink and purple bookcase) Pooh Corner: Children, Young adult (where Bob has his armchair and the silent book club happens) A label in the central hallway reads: "(where they put a bookcase for Today's Donations). Another label on the stairs reads "Hazel's loft apartment" and there is an arrow pointing up the stairs. Grayscale map of the Atlantic showing most of the Americas, Europe, and Africa. There are arrows showing the direction of trade, and each arrow has at least one number attached to it. The numbers match a key on the side that lists the products being traded and their place of origin. There are 15 different sets of commodities listed: 1:Midlands & Birmingham: Guns, Gunpowder, Metalware, Silks 2: Liverpool & Lancashire: Cotton-linens 3: Lancashire: Linens, Cottons, Cotton-linens 4: India: Cottons Cowries 5: Midlands & London: Metalware, Silks, Ceramics, Glassware, Guns 6: London & Glasgow: Credit, Shipping Insurance 7: New England: Beef & Pork, Fish, Rum, Wood, Whale products 8: Mid-Atlantic: Grain 9: Chesapeake Colonies: Tobacco 10: Carolinas, Rice, Indigo 11: Caribbean: Sugar, Molasses 12: Brazil: Coffee 13: Brazil: Gold 14: Mexico / Peru: Silver 15: Britain: Grain, Manufactures The map has a set of grey arrows going from West Africa to the Americas showing the number of enslaved workers transported. The arrows are sized relative to the numbers. The largest arrow shows 6 million enslaved workers going to the Caribbean. 3.5 million went to Africa, 650,000 to the Spanish colonies in Central and South America, and 400,000 to North America. A key in the bottom right lists a set of African kingdoms that participated in the selling of enslaved workers, including Benin, the Oyo Empire, Dahomey, the Ashanti Confederacy, the Kingdom of Allada, the Kingdom of Whydah, and the Nupe people. These kingdoms are outlined on the map. Black and white drawing of a snail, made of abstract lines and shapes. The snail looks truculent, and you'd not want to cross him in a dark alley somewhere. You laugh, but there's nothing here but the snail, and you have no sense of how big he might actually be.

Hey @tkingfisher.com, thought you might enjoy the fruit of an illustration challenge centered around your Wizard’s Guide to Defensive Baking. I believe the illustrators are mostly students or amateurs hoping to develop their skills, and the challenge was to focus on one character. From Facebook.

vaccines let autistic children become autistic adults
autisticadvocacy.org Autistic Self Advocacy Network (ASAN) @autisticadvocacy.org · 10d
At the recent ACIP meeting, members spread lies about vaccines and autistic people. Vaccines are important. They protect us from diseases, and they let autistic kids grow to become autistic adults. We do not need to be prevented; we need support and respect. autisticadvocacy.org/2025/12/asan...
Blue graphic with white text reading "ASAN condemns dangerous disinformation at ACIP meeting." Full statement on website. The ASAN logo appears below. Orange rectangle over a blue background. Text reads, "For the past two days, the Advisory Council on Immunization Practices (ACIP) met to talk about vaccines and things related to vaccination. At the meeting, ACIP members spread lies about vaccines. Vaccines are important for protecting the public from dangerous infectious diseases. Vaccines do not cause autism. Vaccines let autistic children live long enough to become autistic adults. Autism is not a tragedy to be prevented; it is a way of being deserving of support and respect. ASAN will continue to call out and unequivocally condemn any claims to the contrary."
