The No Kings protest in Ann Arbor was all down Stadium from I-94 to the Big House, so that many of the out-of-towners coming in for the game would see it. Yup, got flashed the bird several time. #purplestate #NoKings #NoFascism

MicroBocks is fantastic! Having a wonderful time building and exploring with it! microblocks.fun. Here's an example playing MIDI music while changing the lights on a strand of Neopixels.

We're over 580 students enrolled in PCAS courses this semester, and six sections have only five seats remaining. Time to expand -- again!

I asked GPT-4.1 about Turing Award laureates who had written about education. Of course, I should have remembered Seymour Papert in 1980.

Oh wait...

The State of Michigan will be requiring all high schools to offer an *in-person* CS course by 2027-2028. I like the definition of CS that they're providing -- it includes all of PCAS (lsa.umich.edu/computingfor). (And no mention of AI!) www.michigan.gov/mde/-/media/...

I was just there Saturday. Surprisingly, we weren’t mugged and witnessed no violent crime.

I decided to ask GPT-4o. The reply is telling.
Be sure to brush up on your music theory!

"By claiming that they can contribute to software engineering, the soft scientists make themselves even more ridiculous. (Not less dangerous, alas!) In spite of its name, software engineering requires (cruelly) hard science for its support."

I wanted to find where Dijkstra said this from @felienne.bsky.social's talk. It's in his "Truths" essay. www.cs.virginia.edu/~evans/cs655.... The quote is slightly different, but same (obnoxious) meaning. >>

A natural outcome of mandating CS classes without funding for professional learning opportunities and resource development. #CSforAll (Facebook post)

I meant this part, about manipulating things in aggregate rather than individually.

Sense of belonging in the classroom and school is absolutely critical. Completely agreed. Anant's definition was in the context of "sense of belonging in CS" (what is says in the disposition), so I interpreted "CS" as "the system."

Great fun hanging out with all the student teaching assistants in PCAS and trying out the new Superpower Photobooth! sites.lsa.umich.edu/pcas-photobo...

Okay, maybe I am a bit of a packrat. Just found in my pile of office post-its.

So I asked UM-GPT "Does the Smalltalk Parser do the same thing as a Lisp Reader?" It gave me a good answer that correlates well with what you're saying about Lispy language advantages.

Smalltalk has a syntax (see the famous Smalltalk syntax postcard), but everything is a message. Each object receives a message (with syntax structures like blocks or arrays already mapped to objects) then decides what to do with it (executes a method). Message-sending instead of parsing.

Still trying to find all of the folks I want to follow here. I keep searching for Smalltalk, but what I mean by that isn't what most people mean by that.
