Back in the day I used to use pygments to convert to RTF. But that seems pretty antiquated.
I've been pretty impressed by snappify, but it feels like it's going to fall behind a paywall any second.

VMWare workstation doesn't download guest tools isos anymore? It doesn't even include a clickable link ... Why? The functionality was already there. Why would you remove it?

I am just not that comfortable with my car, TV and HVAC installing updates for some reason.

Rosie got a much needed grooming and now looks less like a sheep. Because she doesn't like to be touched, grooming her is always an adventure.

Pretty good example of me trying to work. Duffy (tan) and Macy (black) are "helping". Both are permanent dogs here. Both rescues, but we've had Macy since a puppy. Duffy is an adopted foster. She loves us but is still pretty skittish around anything new.

This is Gnomey. He is a long term foster, along with Rosie. Gnomey is kind of perpetually anxious. But he loves snuggling with us, which is uncommon in anxious puppy mill dogs.

Rosie and Mateo, two fosters. Can't wait for Mateo to be fixed; he wants to mark all over the house. And he knows how to pull off his diaper. Not a good combination!

I eventually gave up last night on day 3 part 2 in uiua. I could see the light at the end of the tunnel. I would create a mask by folding over the input. But my head was starting to hurt trying to manage all the values on the stack. Maybe I'll give another shot after learning "planet notation".

Progress! The example in the docs was more for partitioning into two sets based on a boolean function. I just needed a ternary function.
Behold this ternary function of beauty uiua.org/pad?src=0_14...

I just spent like 20 minutes figuring out how this "simpler" code for an if-then-else works. Hint: Read the ∩ both docs, and remember that ▽ keep is a dyadic function. This whole language is a giant troll; why can't I stop doing it?

I didn't solve part two, but I'm proud that (with help) I was able to write this.
Learning a new programming paradigm really is humbling. Uiua is probably a bit too crazy for me.

The "trick" is using ⊞=, that is make a table using equality. Table is like cartesian product. So we start from two 6-element arrays and produce 6x6 matrix. Then from there count the 1s row-wise, square, and sum. Very different paradigm than I'm used to.

Wow, open source LLMs are really, really bad at tool calling when used as (multi-turn) agents. gorilla.cs.berkeley.edu/leaderboard....

Hey, I was able to follow someone on mastodon. Here's another post to see if they can see me. Enjoy a dog pic for the inconvenience.

Last night right before our bed time, a local dog got loose and was running around our area. My wife and I drove over and we quickly spotted the dog. With the help of a few other people, we trapped it inside a church playground and eventually caught her!
