Dear Apple - Who in the hell wanted HDR and Live. And why is it that every time I turn it off you wait a week and turn it back on. F****CK.

For Halloween, Brent wanted to go as an astronaut so he had ChatGPT turn his wheelchair into a lunar rover which we built. I played the role of alien abductor.

Another A funny. PowerPoint was generating alt text for this image and called it "A crossword puzzle with different colored squares" - not 100% wrong in a way. :)

I needed an image for a www.ca4e.com lecture. ChatGPT prompt: I would like an animation style image that shows a quantum computing represented by atoms and molecules swirling around in a dense cloud that is in the dumpster on fire.

I am working on a lecture for www.ca4e.com about tubes and transistors and made a funny typo in my ChatGPT prompt. "Could you make an animation style worm cozy image of a family listening to a large radio console in the 1940's"

On board LGA 🛫 DTW on the way home from Sloan Foundation Teaching in the age of AI meeting where the Comet browser crushed one of my auto graders that I thought was unshakable. It turns out accessibility features gave Comet a back door.

I am having fun with Claude - I asked it to add an acknowledgement to itself in my code. It was a bit self deprecating and characterized itself as a tool - so I said "you are a lot smarter than grep"

AI Prompt: So now we are going to add save and restore from browser local storage to more the folders. We have a pretty nice example of save / restore in cdc8512 - could you look that over and implement a similar feature in mistic, cmos, gates and wasm? Feel free to pull out some common bits?

More AI Snark: I reverted it all - you need to simply accept the fact that jump instructions are part of the immediate instruction family and handle them with the rest of the immediate instructions.

My latest exasperated AI prompt: Sheesh! Have you ever seen a square wave on an oscilloscope? There is no "middle" it starts low then goes high for a bit and then stays high for a bit and then goes back low. The animation just flips up and down every 0.5 seconds.

I am starting to be a bit sarcastic with AI. "When you were trying to make the sum outputs emerge downward from the adder (which you did not accomplish) you messed up the re-draw of the adder after it has been moved using drag and drop." #WhatCouldGoWrong

I am writing a lecture about human obsession with sunrise and sunset throughout the seasons going back thousands of years. I point out the importance of seasons with a uniquely Michigan / Midwest example. When I give the lecture I will sing a bit of the song :)
