Just got a college-wide email from the Dean which included 5 paragraphs. 2 different fonts were used, and 4 different font sizes. Am I the only one who takes umbrage at this?
"Paste and match style" is there for a reason!
(or yknow just write your emails yourself)

I just agreed to referee a journal article, and before I was allowed to see the article they showed me this notice:
"This journal does not currently allow the use of Generative AI or Al-assisted technologies for peer review."
First time I've seen something like this- it's good I think!

Still grateful for when Christie's Auction House presented me with the original Pascaline calculator. Such a wonderful gesture of mutual respect. Thank you Christie!

My high schooler reports that all the students objected when the teacher presented 3D-coordinates with z pointing “up”. The teacher was shocked that they would do it any other way. The kids all agreed that y-up is far more natural, since that’s how they do it in Minecraft.

Super-ambitious project by Jonatan Nielavitzky: a 3D printed Babbage Difference Engine! He says it's a work-in-progress but it looks pretty polished to me.
Show him some appreciation on youtube if you have a moment! (I'm trying to encourage him to keep going)

Just saw this old machine with tons of oddities: BOTH 10-key and “full” keyboards, 3-pronged digit shifting crank, 2 big asymmetrical carrying handles. Gotta look at all the pictures.
