you can still teach math! I started volunteering in my local highschool Math III course. Then, ended up taking on a course teaching 5 kids HTML, CSS and JS (we build wack-a-mole). NO! the mole goes IN the hole!!! (most fun part of day)

Learnings From Coding with AI (Claude Code): It's hard to believe there isn't some thinking going on here. Claude admits its fallacies.

Only in New York, at JFK checking in, told the lady that my extra bike charge of $200 was nothing compared to the hotel for 450 last night. She said they should’ve bathed you for that much.

Learning From Coding With AI (Claude): It's easy to get lazy and watch Claude generate engineering debt. I keep adding new rules, but I'm up to over 37 rules now and that seems to be more than it can follow. It violates them all the time compared to when I had fewer.

Learning From Coding With AI (Claude): Always double check that AI doesn't throw things away. me: what did you do with all the nice compare stuff claude: You're right, I inadvertently removed the nice comparison view functionality...

Learning From Coding With AI (Claude): What AI excels out is things like "create a react component that views JSON in a collapsible way only showing shorter content directly, but providing an expando icon for larger sections.

Just learned this JavaScript console.log trick from Claude. No need to mention name twice! (go DRY)

Seriously @microsoft.com and @office365.bsky.social My first experience with PowerPoint and copilot gave me this answer. Then, I was curious about the billing side of this since I'm told the price went up to include this. Copilot charged me a credit to tell me it can't help.

I wonder if ChatGPT makes ridiculous comments like this because it finds it in a significant amount of code on the Internet? #OpenAI @chatgpt.bsky.social

OK, this is a little scary. My personal website, peterkellner.net, is hosted on GitHub pages and I got this this morning.

This is what ChatGPT thinks.

I guess I should have known this, but I didn’t. I thought the two arrays would be different.

Crazy happy with new 6K Dell monitor. It's iPhone quality screen but on 32" of screen! The slight jaggies on my old 32" 4k monitor always bugged me a little.
