It reminds me of Vlasta's old LWN articles named "Patching until the COWs come home"

I spent last week debugging why my machine was dead. The symptom was that it would turn off right away when it's turned on. I suspected the root cause was either the CPU, memory, motherboard, or power supply failing. So I replaced every component with parts from another computer, but it still didn't work.

The root cause was that the power button of the case was broken, causing it to always appear as if it was pressed, so it would turn off every time I turned it on. That was totally unexpected. I just replaced the power line with the reset line and it works fine now.

not sure why it's so common to refer USB flash drives simply as 'USB' in Korea.

once I asked my friend:
me: Can I borrow your USB flash drives?
friend: Why are you saying like that? you can just ask to borrow 'USB'
me: Well, USB is just a bus specification...
friend: What... (she gave a really weird look)

I recall @vbabka was very welcoming when I sent my first patch to linux-mm in 2021 (thanks to email archives! :D)

Oh the irony on poor Kent:

list _or_ the maintainer, then fuck you."

Damn archives, they should be wiped after 2 years max. :)
