My project this weekend was to build two patio side tables. However, I wanted to use only wood left over from previous projects, the plans were important, which meant I needed CAD. But uh… I literally forgot all the CAD stuff I learned 2 years ago. Hey, FreeCAD has an MCP server, let’s get AI to do it. I spent all day Saturday prompting qwen3.8 and did get a plan… with no dimensions. I would not recommend this path. Tables are built, btw.

On plane #3 to home from IETF 125. I am exhausted. Shenzhen was nice. It is a clean, friendly city and very affordable.

I decided to screw around with an ESP32-C6 board I bought awhile back but never got around to playing with. So I decided to make the lights blink using Rust. That took entirely too long to figure out because a lot of the guides are out of date and the HAL has changed drastically. Out of frustration I started using Gemini but because its training data is a few months old, that was one false start after another. Then I went to OpenCode and that worked well because the tool-calling was able to iteratively get at the problem. An interesting experience.

Caught an agent issuing a mount command this weekend. It didn’t work because the mount was embedded in another command that was all messed up, but still…

I created another #matrix bot. This one sends meeting reminders on a schedule and via chat command. It uses an iCal fetched via http for the event data.

This old meme has been going around for years, but in the aftermath of the AWS outage there has been some pushback on-line about it. And that's a good thing, because it is likely that people new to the industry are not in on the joke and might take the meme more literally.
This meme was never about DNS being unreliable, but about the nature of troubleshooting issues in that DNS is so reliable many of us assume we have set it up correctly and overlook our mistakes with DNS when looking for root causes.
It is unfortunate, but way too many people function off of received opinion, and AI is likely making that worse. FWIW, I did once work with an operations manager who insisted we hardcode IP addresses because DNS used UDP and UDP was "unreliable".

One of the things I don't like about the rdap client I maintain is that the text output is great for viewing the information but not so good with cut-n-paste. So I started hunting around for a text serialization format that works with serde, and really the only one (other than JSON) is YAML. So I tried it. Yuck. It was too verbose.
The alternative is to create a custom text serialization, and that sound awful. So I thought, why not RPSL? And well... I have started down that path. There is a good bit of custom logic in doing this as RPSL mixes object type / role / contact kind into one attribute name. But the format is good for conciseness and readability.
Of course, RFC 9537 redactions start causing problems, but there will just need to be some more custom logic for that. Ugh.

It feels like Fall weather and new work lights are now up in the garage… this means one thing: time to do some wood working.

Teaching myself #riscv I learned a couple of things. One of them is that if you want to experiment by using qemu to emulate Linux on RISC-V, you can either search the internet looking for the right incantation and image file for qemu, or you can use the “—arch riscv” option with Lima VM (lima-vm.io), which you should be using for all your VM and container dev anyway.
