Hat jemand eine Empfehlung für einen #valetudo fähigen Saugroboter der mit 4 cm hohen Schwellen klar kommt?

This is next level infosec shitposing:
"It is the FreeBSD analogue of Linux's Dirty Pipe, CopyFail, Fragnesia, and Dirty Frag — except we gave it a BETTER name, with a BETTER logo, on a BETTER website. The other bug websites? Disasters. Sad. Many people have told us this."

At this point the #AI Overview of google search is a security threat. It tried to convince @npub1f7f…9kps and me that the Pixel 7a has MTE, when in reality the feature first appeared on the Pixel 8 half a year later.
Someone could have bought the wrong @npub1kwa…e0nj device.

Apparently the #EU is introducing new product labels for smartphones and tablets that include #repairability scores and battery endurance information.
There is also a document on the repairability scoring system including how many steps you have to take to replace primary parts, parts availability and minimum duration of guaranteed security updates.

This is really awesome!
