@jwildeboer Actually this has been useful. I need to register a couple of domains and this was handy.

Thanks!

This is a joke the AI guy is now sending reviews to patches related to a Magnetometer - the guy went from wireless driver to HSR/PRP to Magnetometer. In a week or so.

*sigh*

@gregkh a pattern I have seen recently is new people on kernel reporting bugs on random subsystems. I am pretty sure they just feed the code to a LLM and send whatever it found.

E.g yesterday I got a review on a patch I sent a year ago on protocol that is pretty uncommon. After talking to the reviewer, it is clearly an AI. It is by the way, the same person that sent a 22 patches series for rtl8723bs that you needed to review :/

@ptesarik Shouldn't docker be using iptables-nft by default on openSUSE?

Or am I missing something?

The kernel patch series removing IPV6=m is out! I am quite happy about it and I hope I did not mess up :)

A lot of people were CC'ed, sorry about the noise ^^

The fact that they crafted this song just for an anime episode is quite sick -- https://www.youtube.com/watch?v=XoodunTw0kw
