"It’s odd to me to see a push for the experience of a website be oriented around a chatbot, instead of a chat being a complementary feature of the website. Having a chat agent be the main feature of website seems like it’ll lead to too much for a user to do."

Here's a simple goodie CSS tidbit. I've had a mega-bookmarks website, and I recently remade it using Hugo, because the previous iterations were a bit to unwieldy to manage. To enhance the design of scrolling, I customized the look of the scroll bars using the following snippet!

This article does make me wonder. To use AI in schools or to not use AI in schools? The prohibitive approach would seem archaic, but at the same time no, because students can practice discipline in school. To practice discipline in school is certainly a valid point.

The rise of AI tools forces schools to reconsider what counts as cheating
Student use of artificial intelligence has become so prevalent, high school and college educators say, that to assign writing outside of the classroom is like asking students to cheat.

The wizard is out of the hat! Today I had the privilege to give a presentation that I've been working on for several months at UtahJS conference. This was my first ever conference talk, and I wanted it to be a good one. I decided to present in a way that I've never seen happen in a presentation!

"When you're hiking, those little steps might not seem like much — but they're exactly what get you to the top."
I'm a big time hiker, and a client said this to me when our project started to show fruit. I love this because it's exactly what I know and remember while on hikes.

This suggests that rewriting an essay using AI tools (after prior AI-free writing) engaged more extensive brain network interactions."

I just finished the book #supercommunicators! What a game-changer. Personally, I feel like I need to strive for better communication and understanding. I can observe in my own life how much I may come off as insensitive, when that isn't my intention. I can improve my own talk to improve connection!

I recently went on a vacation to Europe, and I was fascinated that sunset time was later than in the US. This confused me because I didn't think there would be so much sunlight time. But then I remembered more extreme latitudes experience harsh sunlight differences. So I thought to look it up!

Another random 3D project idea. Show the earth rotating the sun, and demonstrate the ecliptic path of the sun in relation to the earth. The path can be a line across the earth, and the path can change depending on time of year.

Oh wow, this highlights a way to not use AI in software engineering. A study found that an AI slowed a software engineer (around 19%) when the codebase was quirky and large. Software engineers had to correct what AI was suggesting. I'll read the study when I can.

Part of my recent software exploration is WebHID, and I am surprised at what I can do with it! For example, I've been experimenting with connecting a Nintendo Joycon to the web browser. Some of the things related to HID seem beyond my comprehension, but that won't stop me from learning more!

Random 3D project idea... If I know the sun position, and if I know the altitude and GPS position of planes, could I find where the plane's casted shadow would be?
This sounds fun, but I don't know when I would do it yet. Thought inspired by shademap.app and seeing the shadows of planes.

I made a very simple fundamental React mistake. I coded a hook to use Howler.js, and a prop into this hook was the source of an audio file. For some reason, the audio file as being loaded many times. I realized that I passed the audio source as a string array into a useEffect hook!

Bug! Three.JS's vertical is Y while 3D printing's vertical is Z. In my project, I thought converting ThreeJS coordinates to 3D printing would be a Y and Z flip. It turns out my GCode would output a mirrored model. The solution was to convert the X value to the negative! This was a funny bug to me.

While finishing up my first freelance project, I saw regular “Mixed Content” warnings because I was accessing a local HTTP server from an HTTPS website. To solve the problem, I ended up using AI to generate a Github Action to deploy to a DigitalOcean Droplet.
