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.

If anyone has this adapter and is interested in this useless research, please send screenshots lsusb or device manager for this. Thank you so much. I need this.

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.

[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”.]
