An Adobe Acrobat window with a popup saying "This appears to be a long document. Save time by reading a summary using AI Assistant."
I hate this.
(I almost never use Acrobat so I just saw this for the first time.)

New video: the Kensington Adding Machine software for the Mac from 1993. #skeuomorphism
This was originally planned as an April Fools video, but really it's not all that foolish.

I was planning my sexennial April Fools Youtube video, but didn't quite get it done in time. It'll be ready sometime within a week!
In the meantime watch my previous April Fools episode.

@tienchihmath.bsky.social Woah I have just been thinking about this! Nice-
with the original box!
slide rule with built-in clinometer
Too expensive for me, but very cool slide rule with built-in artillery clinometer!
But it's not linked properly! The bottom two are good, but the top one links through each of the others. 👎

I made this sign in 2017. Sadly still in service #nokings
Procrastinating other things so I made this stupid video after going down a rabbit hole this weekend

Quoting from the intro: “more on him later”
Made the video editing easy- it’s never boring to look at while it’s going
a big galton board
New video tomorrow! Including possibly my favorite writing yet for the final line. But I'm never too good at telling what other people will like...
Here's a sneak peek for my faithful bsky folks- this thing is too big for my usual setup!
An old typewriter
An old typewriter
Spotted at a shop downtown. Wild old Hammond No 12. Crazy key layout with lots of special characters.
I always make them do homework by hand since this is the best way for them to learn. In the past, students who did the homework well learned the material well. This has changed dramatically just in the past year.
For fun, one of those two plots is actual student data- each point is the HW & quiz average of a single student. The other plot is decoupled per-student and randomized to intentionally destroy any correlation. Can you tell the difference?
Two plots of homework scores vs quiz scores, showing no correlation
Concerned my calc 2 students are using AI to do all their homeworks, since the ones getting great HW scores do terribly on the quiz given in-class the next day.
Scatterplot of HW scores vs quiz scores shows no discernable correlation.

Some days I have productive research shower thoughts. Other days:
Picture of a guy standing next to a weird tall abacus-like thing.
Looking at a mathematical gadget on Amazon, and the product page shows this picture. (It is not a picture of what I'm trying to buy.)
Is this a real thing? I'm guessing the picture is AI generated, but I still want one to gesture near.
Spotted at the goodwill: a SCM “Typewriter Ribbon Cartridge” in the original box! #didntgetit
I love the design! Impossible to mechanically lose track of the count, easy to "read" just by how it feels on your hand. Hard to move from one position to another, but that's kinda the point. You can pick up the ball, get knocked over, nothing's gunna mess it up.
A US football "down indicator"- wrist strap with a loop around a finger
I learned from a YouTube comment about this thing- the Down Indicator used in US football. Very interesting! Do football fans recognize this? You loop the thing around different fingers to keep track of what down it is (out of 4).
