<heat> geist, yep in this case the code moving is actually relatively important
<heat> but yeah, still code moving
<heat> the ways in which i piss away time are astounding
<heat> i pondered implementing iommu support, read the vt-d pdf for a bit, decided it was too hard, committed some outstanding stuff, added some BS wrappers, moved code, watched a football game, played an embarassing amount of bullet chess
<heat> and i did 0 of what i actually need to do
<geist> yuuuup that's me like 80% of the time with my free time
<geist> i've surrounded myself with an infinite number of projects that i can just touch on for 30 minutes at a time
<geist> it's fun, but not particulary fullfilling

<heat> all of these things are usually fun and usually fullfilling
<heat> i have an insane capacity for finding new creative ways of wasting time and it is frustrating
<kof673> <vaguely reads scrollback> from what i understand punch cards for *users* were not necessarily loud, you just handed your "deck" to the secretary/whoever and waited until tomorrow/whenever for the results. person working in the computer room is different though :D
<kof673> aka batch
<nikolar> heat: i imagine that's most of us here too

<geist> indeed, osdev eventually turns into a factorio situation
<geist> it's a complex enough, self sustaining piece of software that you can work on it forever
<heat> e n d l e s s t o r t u r e
<nikolar> čpč
<nikolar> lol
<heat> cpc!!
<heat> found the slav

<clever> 2024-12-08 02:40:03 < clever> from reading the code, it looks like thats a .reg section, but is that under `Section Headers:` or `Segment Sections...` ?

<bslsk05> ​twitter: <PGelsinger> Every Thursday I do a 24 hour prayer and fasting day . This week I'd invite you to join me in praying and fasting for the 100K Intel employees as they navigate this difficult period. Intel and its team is of seminal importance to the future of the industry and US.
