My android phone kills the chrome app very often. It is painful that I can't see system logs. I suspect it was the OOM killer that kills it.

@vbabka btw how do you think about maintaining a slab/experimental branch so that it can be tested first even before being reviewed and went to slab/for-next?

Welcome to the cycle of generative AI making search worse.

Quora uses ChatGPT which hallucinates an answer to a nonsense question.

Google Search picks up this nonsense answer from Quora which has high page rank and treats it as an instant answer.

"Subscribing" to mailing lists via sourcing a pop3 mailbox from lore.kernel.org now works. Should be of particular interest to gmail users.

I'll document after some more initial testing.

Fun part of building a home server with a domain name is the public IP can change. I wrote a script updating DNS A record periodically because of this. This is not a perfect solution though; DNS propagation time takes some time. But it should be sufficient for my service.

small progress on the kernel testing side project: I did setup LAVA instance in addition to Jenkins and made it publicly available.

it took few weeks due to issues with hardware :(

this is home server so can't provide excellent stability and uptime but here it is:

my jenkins VM was mysteriously shut down continuously without any log. I spent some time figuring out why, but it was the host's OOM killer that killed it. chrome tabs that I forgot to close was eating up 100% of the memory. fun ;)

but 32gib for a browser was too much? was it memory leak?
