Home without too much stress (I’m not prepared to call any day that starts at 04:00 stress free!) after a stimulating #XMLPrague conference and my first face-to-face working group meeting since, uh, the before times. Stuck to outdoor dining as much as practical. Wore a [expletive] mask indoors. COVID negative today.

@ndw Best of luck!

@graydon Yes. I did shave a bit. The most disappointing realization was that my Flo Mask doesn't fit well enought to wear all day. I resorted to N95s mostly, but CO2 suggested the ventilation was pretty good.

@ndw Hurrah for good ventilation! (And for being practical about the gasket seal.)

Anything with a gasket tends to have idiosyncratic fit; I've gone through seven to get to one and a half useful fits. Guessing wildly from a small picture, you might find the Honeywell RU8500X a good fit. (If you can find one; it's intended for a medical setting and sold like it.)

(Just got back from the dentist; extra-twitchy.)
