Ive got a couple of PLCs that I keep meaning to pull out of old hardware before it gets scrapped for the stainless value.
None of the PLCs that I use at work are networked, and they are getting ridicules in their pricing when safety stuff is now involved







I’m no dev, but did do my HND in computing some 25 years ago. I have also tinkered with scripts to solve an itch and have has plenty of VBA and of late DAX and power query.
I did a project for myself around a year ago that was much larger than I normally would these days and I used Gemini. It was a constant battle with the LLM (man it’s hard not to gender and personify these LLMs) to keep it on track and not keep breaking shit all the time. It struggled to writ valid rules for it’s own firebase/firestore. It generally felt like a bad time.
This past week end I got codex to migrate the PWA from google’s services and database into a selfhostable docker stack. It was a pleasure, it documented the whole process map, built a full test environment, followed through and imported my data. It the suggested a few improvements. It even rewrote a a complex equation that Gemini could nust not get correct and added manufacture safe/max bounds.
all this to say ‘yes, modern agents do seem to do a good job of a codebase that they have never seen’
