All this time I never clocked the Pydantic ConfigDict is what the dict has to conform to, not necessarily instantiate! 😅

I guess thematically last year I did a lot of work to be able to verbalise data structure and then to operationalise that through genson-cli, and this year I’m working to verbalise flow
To say anything seems like you need to decide your rules to abide by and prove why they’re operationally valuable

Unsure if my realisation about making data sources immutable in model training pipeline code is completely trivial or totally off-piste (“hardcoding corpus version specifiers in an immutable data registry = good, input source should not be runtime configurable”)

You are experiencing code casinofication by vibe code lottery I’m experiencing it by guessing which four letter names will be sufficiently distant to existing PyPI packages’ we are not the same 🎰 🎰 🎰

Turns out the electricity transmission network looks pretty cool when animated in Blender ⚡
The idea is the animation shows flow direction along each line, though right now the directions are completely made up until I get my head around PyPSA.

kicking myself for somehow still not internalising you can do mv with braced path sets llike /path/to/nested/{src,dest}.py

Something like: the t-string pathlib idea I blogged about recently+ versioned artifact layout + I/O checking guards... etc etc
