I really don’t see the issue. If the work account uses Google or Microsoft I use their respective web apps and export an ICS link to see the blocked slots in my own personal calendar.
For my own personal calendar I use CalDAV, which is widely supported, and an app that can import ICS links. (Self-hosted Radicale server and the Calengoo app for mobile and desktop, for the curious.)
I beg to differ. I’ve been backing things up to optical for 25 years now with minimal issues. CDs could be easily scratched but it hasn’t been the case for DVD and BR.
M-DISK uses in-organic substances that make the discs mostly immune to exposure but it’s a more recent invention. Proper storage and handling still goes a long way towards protecting discs even if they’re not in-organic.
