After a long injury, I got back to slowly running on the treadmill/bike/elliptical at the gym. IIRC, my garmin qualified its VO2Max results by saying I needed to run out side for some period of time to get a more accurate measurement. I guess there is something about the running metrics it collects that has a smaller error range.

Hopefully something as optimistic as this and not the Quiz Broadcast :) https://www.youtube.com/watch?v=22mt0cVyW5c

dropping off the bus is the best case fail really. Its more annoying when writes become slower than the other disks often causing confusing performance profiles of the overall array. Having good metrics for each disk (we use telegraf) will help flag it early. On my zfs pools, monitoring disk io for each disk, smartmon metrics help tease that out. For SSDs probably the worst is when there is some firmware bug that triggers on all disks at the same time. e.g. the infamous HP SSD Failure at 32,768 Hours of Use. Yikes!

exact same reaction. I remember hearing about "regrowing teeth through sound waves"... in 2006. https://www.cbc.ca/news/science/dentist-engineer-team-up-to-... Can't say I have heard it offered anywhere yet....

Its partially there. C and D are still not in the global tables according to routeviews ie. 185.89.219.12 is still not being advertised to anyone. My peers to them in Toronto have routes from them, but not sure how far they are supposed to go inside their network. (past hop 2 is them)
