Oh great. If you see an elephant with an IR flashlight on the side of the road, beware. https://www.ndss-symposium.org/ndss-paper/targeted-physical-evasion-attacks-in-the-near-infrared-domain/

I need to find a better way to do this.

@mcdanlj tried a simpler project from scratch with a newer model. Took about an hour, then each new feature took 5-10 mins each. Saved many hours of work. https://github.com/xjamesmorris/pskreporter-tool

@mcdanlj yep, I assume they will abstract all of this away somehow. btw, it is doing some impressive things already. I said "you are a very senior developer and keen to impress with clean, bug-free code" and that seemed to have a big impact on its attitude. This is for controlling a radio via C-IV over serial, a messy undertaking especially for cross-platform UI and hardware. I told it to make a radio simulator which listens on a local UDP port for testing & it saved me probably hours just on that.

@mcdanlj very useful, thanks. I think you may be describing the context window? I've seen it in other non-gen AI areas.

@mcdanlj Thanks for the info! I'm expecting to need to provide a lot of structure & prompting, which is the real aim of the learning exercise for me here, but I was surprised it did some very random things that did not have any internal logical consistency. This is with Haiku, so perhaps it will be better with one of the current models. At some point I gather we will have an agent which also does the prompt development & managing of the coding AI?

I've been experimenting with having Claude finish an unfinished coding project. You've really got to watch it like a hawk. It does some inexplicable things like removing important comments, fixing non-existent buffer overflows, breaking protocol parsing etc. What am I missing?

I love how vibecoded commits are called vommits. It's so perfect.

@dlharmon thanks for the pointer to those papers. I wonder what else NIST has there…

Ok, nerds. Here’s a photo of a beta XBox (One S?) in dazzle camo, from a random hallway cabinet in Redmond.

I'm hoping to reproduce this cavity stabilized oscillator design from NIST but at 12 GHz as an ultra low phase noise reference clock for the vector signal generator. This nonsense is optional, the clock could be as simple as an LMX2594.

These pipe couplings are very close to what I need for a TE015 resonator at 12 GHz. They need some minor machining, polishing, endcaps, coupling loops.
