I need a progress bar for something with a wildly varying estimated time to completion —
but I still want to show constant progress.
So here’s the 💡: a dot moving at constant speed along a space-filling curve (Hilbert?) and dynamically adjusting the curve’s resolution as the ETC changes.
Thoughts?

A friend gently reminded me on my birthday: “There’s always a number base where you’re in your 20s — and the number of such bases keeps increasing.”
I’m more in my 20s than ever!

It’s a special kind of sadness seeing the entire genre of art made with computers that I have been pursuing since the 70s ruined by AI slop. I have never been less motivated to share new work in my life. 😿

Accelerating maps with join-with
We designed ClojureDart maps to be more regular and deterministic than Clojure’s, making it easier to optimize batch operations. For a while, that potential...

There is no longer the satisfaction that your consumer is a human (who might write a comment, say thanks, post on HN, etc.); nor the cred that comes from people reading and remembering the author, posting on HN, etc.
That is, it totally destroys the incentive structure.

Okay. A lot of « optimizations » are about tricking our brains into thinking they do something good for us.
Are there groups looking into designing around our flawed brains rather than against them?

The most distressing part of the decline of reading is that reading's core purpose is to not only present facts, perspectives, and information, but to expose us to the mechanisms of thought itself.

This bug was weird. All of a sudden code stops compiling. The only change? The reader now adds end source location metadata. If I add only end column or end line it’s ok. But not both. The failing form? (ns foo (:require [bar :refer [x y]])
