openslide on Apple silicon?

[Jon Sauer]

Hi again,

For your information, the machine learning I’m working on is in support of my daughter who just moved from Maine where she was the only pediatric neural oncologist (children’s brain tumors) in the state. She may well be the same, or at least one of very few,  in VT in her new position at Dartmouth-Hickock. I’ve followed her to VT to continue work on our grant which I can do as a semi-retired EE/physicist.

Cheers,
  Jon
