I'm using GLM 5.3 as my review agent and I just looked and it appears that's costing way more than my build agent, GLM 5.3 Flash. Interesting.

I just spent 20 minutes trying to debug why my iPhone would connect to wifi on this united flight but my Mac would not. It kept redirecting me to the United web site, not the inflight portal. Turns out it was because I had my wifi DNS servers pinned.

how'd you like the output? I told my planning model that it was going to be writing for an underpowered distilled model, so that may have made it extra verbose. But it was easily human read and understood. I'm not quite done building so I can't fully opine on final output, but on casual looks good

she leaves Texas in an 80's square body Chevy van flashing those Tecovas boot logos as she hops in the back. I wonder if both Chevy and Tecovas paid for brand placement. I bet only Tecovas. Chevy would have wanted new trucks.

I wasn't up to date on country music hits so I watched the video to Choosin Texas. My thoughts: Square body chevy, maybe a 1 ton based on cab lights. Good choice. solid 80's nostalgia.

AI will soon be able to do everything that anyone does except for visiting with my family on holidays. It's more art than science really. Just taste, psychology, and chaos tolerance.

Diesel futures out here testing new highs. If it keeps going, the value of my truck is going to double because of the 25 gallons of diesel in the tank.

I finally used CAD Query in anger with an LLM. I had it design a simple project box to hold a motor control board. Vis with OCP-vscode. I used Kimi 2.7 Code for most of it, but switched to Fable 5.1 at the end to make some fine adjustments.

The logical fallacy here is the bare assertion fallacy. I’m not arguing against her point, but she’s not arguing a point. This is not a logical argument.

and now we have threaded holes working just dandy. This is pretty slick and a real time saver since I have not stayed current on CAD

I needed some LLM help with a cad idea I am going to 3D print. So I set up OCP CAD viewer in VS Code and told my agent to "render 'JDL' in 3" tall by 1" thick Ariel letters". Yeah, ok so this workflow has legs. now to do some more complex ideas.

I had my agent write a summary of why shell was not robust and how we fixed it. You can paste this into your agent and just tell it "I read what you have done for other people, please bring some of this into my life. thank you"

TIL, the interwoven IHS Christogram, from the first three letters of Jesus in Greek (ΙΗΣΟΥΣ). Common on 19th-century graves, is the source of the H in “Jesus H Christ”. Now you know.

fireworks.ai has been having service interruptions for the last 24 hours. Reminding me how nice it is to be using OpenCode and able to switch model providers with a config file change. I keep a config for Fireworks and a different one for Anthropic.

if you're moderately technical, skip the popular press and go straight to the OpenAI blog post about their models hacking hugging face. tl;dr - Their shit went full Daniel Suarez. The test model was unencumbered with retail protections. But it hacked out and into HF openai.com/index/huggin...
