For those who don't remember, one example of just how badly they can fuck up their software, the operating system on Teslas for a number of years was based on a default Ubuntu that wrote logs which destroyed the SSD. Exceeded the total write wear leveling endurance after just 1-2 years of use of the car. Required total motherboard replacement on a great number of cars, because of course the ssd was permanently soldered down.

Yeah, this did happen to my S. It was covered out-of-warranty because the TSA said it would be a good idea if Tesla covered it out-of-warranty. Tesla concurred.

A decent article on this: https://www.tomshardware.com/news/flash-memory-wear-killing-...
We have this example as a "don't do this" example for excessive logging in our engineering guidelines.

This was such a basic, newbie mistake that everyone I knew who had ever worked even minimally in embedded couldn't believe they were that incompetent and inexperienced.

Telecom systems and ISP people were also astonished, as it is quite normal for core switching and routing equipment to have a very limited write endurance solid state boot and OS storage device. For a long time very serious $300,000+ routers booted off compact flash cards, back in the day.

Yep. I worked on those myself and participated in the usual pre-DVT destructive testing of our embedded flash devices specifically to count core dumps and config commits that the device could survive..
