a foolish mistake: can't open my phone's card wallet because of the strap I bought yesterday...
Should've realized that I can't have both :(

Whiskey's bit expensive to drink enough (TM) :P
I'd rather drink Soju sir (about $1~$3 per bottle)

In the ACPI specification; the character representing ACPI root namespace ('\') seems to be escaped (' and \') and looks like this.
How have people been reading this?

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:
https://lava.kerneltesting.org
https://jenkins.kerneltesting.org

So I measured one change (the SLUB numa locality change) at a time and the data seems to be nice I think? (at least on my old Broadwell machine with 2 sockets)
The "Neither a win nor a loss" situation was because one change was a win and the other change was a loss.
But it's still synthetic hackbench and I wonder how it would perform on network benchmarks - but not sure if I could benchmark this enough on local env cuz I only have 2.5Gbps lan cards.
