This... is interesting. The oldest kid here is taking Calc III, The Calculus of Multiple Variables. There's a whole thing every week where she winds up spending a lot of time transcribing her homework into a more readable form so that she can turn in her work on the assignment's due date. I wondered if an LLM could help with that. I tried out ChatGPT 5.3 with this picture to start. Believe it or not, this contians two homework problem, (and, accidentally, my foot.) I asked "Please write these two math solutions as laTeX and write them to a pdf file." I wasn't too surprised when it replied with --------- "I only have one photo so far, and parts of it are too hard to read reliably to typeset without guessing. From the visible top portion, I can make out a problem that looks like T ( x , y ) = 60 1 + x 2 + y 2 T(x,y)=\frac{60}{1+x^2+y^2} T ( x , y ) = 1 + x 2 + y 2 60 with partial derivatives like ∂ T ∂ x = − 120 x ( 1 + x 2 + y 2 ) 2 , ∂ T ∂ y = − 120...
On Tuesday, I mentioned that I'd be adding Halikey as an iambic keyer to the CWSimon game. Iambic keying enabled by Halikey is something I've been meaning to do for a while, but each time I start, I realize I'm going to need to start with serial port signal inspections, and set the project back aside. This is the exact sort of thing vibe coding is good for, pushing through the parts of projects you don't want to bother with. So, this morning, I put ChatGPT 5.3. A few minutes and a design coversation later, ChatGPT cranked out the web page for me that you'll see in the video below. Here's the app itself if you'd like to experiment with your serial Halikey. Halikey Serial Signal Test Bench Connect to a Halikey and watch for serial control-signal changes. Each change will be logged below with the signal name and new state.
