It’s… complicated. Ugh.
Too much configuration required…
Sticking with regular VMs…

(Update) Time Machine incompatibility
My Mojave machines have successfully backed up to Time Machines, though the message on the Time Machine application says 0 of 0 updated. As such, my initial understanding was incorrect and i stand corrected.
TIL Mojave does not connect to Time Machines which were initially connected to Catalina.
Suddenly I am 5 and I want to fly

retr0brighting with sunlight works!
If you have old plastics which had yellowed with time, have no fear! (and don’t throw away good plastic enclosures!).
All you have to do, is to place the plastic enclosure under bright sunlight for couple hours a day. Repeat until the yellow fades back to its original colour!

Will human transplants change biometrics?
https://sg.style.yahoo.com/transplant-patients-dna-is-replaced-with-that-of-his-donor-124035642.html
9 December 2019
A transplant patient developed the DNA of his donor, it has emerged.
Chris Long, from Reno in Nevada, had a blood test three months after receiving a bone marrow transplant.
Results revealed his DNA had been “replaced” by that of his donor, a German man 10 years his junior.
Four years later, the donor’s genetic material was found in Mr Long’s cheeks, lips and semen. While levels fluctuated over time, only his chest and head hair were unaffected.
HTTPS and Geolocation with web browsers
I’ve starting coding apps to get a javascript geolocation refresher. Switching between OSX and W10 was quite a pain because:
- Safari does not support geolocation over HTTP (no idea why http://localhost/ is considered an issue with Safari).
- W10 Edge supports geolocation over HTTP.
After some experimenting, I discovered Chrome and Brave both support geolocation over HTTP on OSX. Chrome definitely was doing WiFi triangulation because it could return my exact lat/lng whereas Brave was returning the midtown lat/lng coordinates.
