"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?

@kees Haha, will exploit writers be considering a different job after this? (but I guess they are way too creative though)

@ljs lol I recall reading it in "Linux Kernel in a Nutshell" book and I was shocked in the same way

@vbabka It's not declared thrown away - but no one in the company needs my work, and there is no specific task nor requirement. And I can decide what to do.
So I asked if I'm allowed to contribute my work to upstream community and I was told "No, it's our company's property"
I'm not sure why they even hired (even if it's intern) me.

I'm really excited about making Use-After-Free exploits much harder in the #Linux #kernel.
CONFIG_RANDOM_KMALLOC_CACHES has landed:
https://git.kernel.org/linus/3c6152940584
CONFIG_SLAB_VIRTUAL is coming:

Sorry for what you had to go through.
Reminds me of my parents' lives. It hasn't been long since the quality of life in South Korea greatly improved.
My father and mother couldn't even finish high school because they had to work to support their family.
They tried their best not to make me (and my sisters) experience the same thing. I am always thankful to them.
These days the situation is much better. Many people are not forced to work and give up studying. And on the internet you can find most things you need for studying something.
