I do feel impaired around 1000ppm. I get headaches. At home I got a few Air Gradient Ones (no affiliation, but they are great) and connected those to my Home Assistant to turn up the ventilation in stages (above 650ppm go up, above 800ppm again, at 1000ppm max). I also do this for the bedrooms, cause in the night it goes up too.
The article talks about "within the hour". With four people in my living room doing normal things it jumps within 20min to around 1000ppm. If I am wrestling with my kids much sooner.
In offices companies often neglect it.
edit: if you are cooking on gas it also has an immediate effect on co2 of course apart from other small particles
I like Luhmann’s theory better. What i like about it is that Luhmann argues that the smallest denominator of a social system is a realation between two. Habermas says it can be brought down to an individual. Which in my mind defeats the “social” part.
I have SentinelOne as part of my install. Since that got upgraded, my Mac started eating its battery during sleep. Possibly due to SentinelOne's network scanner, as that takes up 100% cpu for awhile when just returning from sleep. So my mac awakes 3 times an hour to connect to iCloud and then adding SentinelOne overhead...
I think I might try this setting (Prevent Wake for Maintenance)
