Looks like there's another March For Science this year. I'll definitely be attending it too. I wish I had known there would be another Women's March On Washington earlier. I would have gone to that too but I didn't find out until afterwords.
It does look like at least one of my photographer friends is interested in going too.
Seems that I'll be attending the Women's March on Washington on 2017-01-21. It should be a great event and also a great opportunity to take a few photos.
Getting there will be interesting given the number of people planning on attending. Plus they're limiting bag sizes and forbidding backpacks. This will make things hard on me as I'll have to keep anything I need in my pockets.
Based on this experiment with ZFS it appears that using 'zfs replace' on a good or semi-good disk will keep the disk in use during the replace.
