@ljs sometimes during kernel compilation, sometimes while shutting down the machine for rebooting...

today I was hit by a kernel bug on the latest mm-unstable and so I was debugging it. but after a few kernel crashes even a normal kernel doesn't boot.... what's wrong with you :(

Not sure if it is a filesystem corruption caused by kernel bug, or they just did happen independently.

I have the last final exam today. haven't decided what to do during the summer vacation yet, but it will mostly involve learning new things and writing some kernel code.

I'm not gandalf, but exams are like gandalfs themselves, endlessly coming back despite my efforts to kill them all.

It was 2004 when I got my first computer, but I don't recall the precise model. it was shipped with Windows XP.

The first time I used Linux was Android on my Galaxy S3 phone in 2013; after that, I started using Linux on my desktop since 2014.

OK so that, minus descriptions of things like mprotect(), madvise(), mremap() and general review and cleanup is process memory done.

Been working on this part of the book (initially I thought it'd be 1 chapter, lol) for at least 6 months.

After a month of basically no book progress due to being away for lsf/mm and ill this is a great relief and keeps me on time after my last reschedule of targets.

Next: OOM killer chapter which, when done, will be released as a sample chapter.

I'm really sorry to hear you guys are having such a tough time. My experience of life may be limited compared to yours, and I may not fully understand, but I'm here to support you in any way I can.

the strategy of utilizing LLMs for documentation might be useful for motivating someone to think "Oh, this is a piece of shit, I should completely rewrite it"
