You know, I actually wonder how many people don't actually realize that social media sites like Twitter didn't exist in 2001. Fully grown adults exist who have never known a world without them, and I imagine it's very easy for anyone about 25 years old or younger to not really believe those of us who were here for their rise when we say that nothing like them existed at the time, even on the internet.

UPDATE: Confirmed! It's real! See ayumi's lsusb dump: https://transfem.social/notes/a9j1rc059tdj0vpx

Today in vendors slipping single bits (or single bit!) of information into weird places:

I am *completely* certain that Google once made a USB-C audio adapter that has a *different USB PID* depending on whether it has something plugged into it.

I am somewhat certain that it's 18d1:5025 with something plugged in, and 18d1:5029 without.

@dramforever@mastodon.social I have this one. When it’s not connected to anything `lsusb` output looks like this: ``` Bus 003 Device 005: ID 18d1:5029 Google Inc.

I recently bought a stainless steel pressure cooker [to replace an old aluminium one that can’t be used with an induction cooktop], so for the first time in my life I now own a cylindrical object with a highly polished mirrored surface.

When I went looking online for examples of cylindrical mirror anamorphic art (i.e. images that appear distorted until you view them reflected in a cylinder), I discovered a sculptor, Jonty Hurwitz, who does this for solid objects rather than just flat images.

https://www.thisiscolossal.com/2013/01/the-skewed-anamorphic-sculptures-and-engineered-illusions-of-jonty-hurwitz/

[The antihero in my story “Crisis Actors” uses cylindrical mirror anamorphism as an “encryption” technique. Wikipedia notes that “A secret mirror anamorphosis portrait of Bonnie Prince Charlie, held at the West Highland Museum, can only be recognized when a polished cylinder is placed in the correct position. To possess such an image would have been seen as treason in the aftermath of the 1746 Battle of Culloden”.]

@gregeganSF Hah, at uni I had a couple of classes with a PhD student, who was writing her thesis about anamorphic art. She found a historic piece called something like “Lover’s embrace” and thought it was a lewd-ish painting. She bought it and actually applied the appropriate transformation, when it turned out to picture sex with full penetration. She was very proud of managing to spend the mathematics department’s funds on porn.

@gregeganSF There is an old tradition of making beer coasters with 2D anamorphic art (originally mostly nudes, nowadays more advertisement), I have seen a lot in Belgium. I can find and photograph some of the ones I have if you are interested.

@gregeganSF Encoding such an image with a highly shaped convex mirror would be interesting, but while anyone might own a shiny cylinder, possession of a complex key would be more damning and demolish any claim to admiring abstract art and coincidence.

When I've expended my dilatory interest in stereo #photography I might play with that.

@gregeganSF
A local park has an anamorphic art piece named Double Play by Robin Brailsford.
A tile mosaic around a stainless steel cylinder depicts a baseball game.
The reflection in the cylinder looks normal.

It is location 14 on this website:
