An over-the-door coat hook I bought yesterday. Right: the back of the packaging presumably showing how to use it. What the what?
A pair of photos. On the left is a white coat hook hung over a door. On the right is the illustration from the back of the hook's packaging, showing a strangely curved and bent hook over a broken door with jagged lighting bolts in its frame, where the top doesn't line up with the side, and a strange circle (out of perspective) might be doorknob.

Either very old dogs, or the editor needs more sleep.

I discovered the wonderful Book Warehouse on Broadway in Vancouver BC yesterday, and came home with 4 diverse recommendations from David! New books! What a great day!

This book was written by me, not AI. From the introduction to my new book "Quantum Computing: From Concepts to Code" from No Starch Press nostarch.com/quantum-comp...
A section of a page from "Quantum Computing: From Concepts to Code." It reads as follows: "Who Wrote This Book? As of 2025, AI-based systems that are capable of producing text (in addition to generating other media) are changing the landscape of writing. People are using chatbots to write office memos, term papers, business proposals, newspaper articles, technical reports, and probably anything else that’s based on text, from love letters to birthday cards. It can be hard to know whether you’re reading something written by a person or the output of a program trained to produce text that is statistically similar to that written by a person. The result is that it can be challenging to know how much trust we can place in anything we read: Are we reading something produced by a real person, or a clever simulation? So, I think it’s important for you to know where this book came from. It came from me, Andrew, the guy whose name is on the cover. Every word, every letter, every comma and parenthesis came from me (or one of my won- derful human editors). With the exception of plots showing actual data and circuit diagrams produced by a library following my explicit instructions, I drew every figure by hand. I used a wide variety of software tools to help me write text, create images, run quantum programs, check the math, and provide other support, but none of them wrote any of the book." The cover of "Quantum Computing: From Concepts to Code" by Andrew Glassner. The cover art is a line drawing of an arcade claw machine reaching into a box of different robots. They are reacting with various degrees of worry, concern, escape, distraction, and goofiness.

Interested in #QuantumComputing? My book just came out and it looks beautiful! This is exciting, mind-stretching stuff. Don't worry that it's too hard - if you remember high-school math, you're all set. Get a printed or e-book now from nostarch.com/quantum-comp... or from your favorite bookstore.

It doesn't look like the Vancouver Public Library has tote bags. Drat! My library card has a list of all the local branches. Maybe one day they'll make it a map with bright dots for the branch locations.

I have a new library card! It's one of the greatest joys in moving to a new city. Being part of the library means being a part of the community. #VancouverPublicLibrary

Yesterday it snowed in Seattle, and in the morning I saw these tracks in the fresh snow in front of my door. Does anyone know what made them?

I saw a photo of a ring-tailed lemur. I have zero knowledge of its anatomy, but I thought for fun I'd make a constructive drawing of it, and it kinda-sorta worked out!

The National Pornbot Center assigns names to pornbots just as the World Meteorological Organization assigns them to hurricanes, in alphabetical order. We're still working through the Ale... section.

Pencil sketch for previous post #art
Pencil sketch of an abstract human person leaning to the right, against a wall, looking down. The head, chest, and pelvis are shown. Each limb appears in two places (arms above and below the elbow, legs above and below the knee). The shapes are minimal tapered cones with some radius variation. The viewpoint is at the side and there's no perspective, so the image appears flattened, as a collection

An abstract person is standing and leaning into the right wall of the image, looking downward. The background is medium brown. The person is drawn in masses on 3 layers. In back, filled with black, are the head and left limbs. The chest is in the middle in gray. The right limbs are closest to us in very light red. The arms are drawn as one shape for bicep, and one for forearm and hand. The legs are a thigh, and a combined calf and foot. On the far (black, left) leg we see a kneecap.

Artists: How do you distinguish different grades of pencils, particularly when you have several from one manufacturer? They look identical and the grade markings are small. I've put these big labels on my woodless pencils. Is there a better way?
Four woodless pencils. Each is black or dark gray, making them hard to distinguish. I wrapped a piece of yellow tape around the end of each one, labeling it with the grade of the pencil's lead. The labels are H, 2, 4, 6 (for HB, 2B, 4B, and 6B).

Red = closed-eye squiggle. Black = built character. #KickeyBean
A little drawing exercise. The red squiggle was drawn with closed eyes and no intent. Then I opened my eyes and tried to find a character. I saw a dog, and drew it in black ink.

First drawing with new pencil! A Pentel GraphGear 1000 0.5. I was a little afraid to really bear down in the darks, but now I know the pencil is plenty strong enough.
