We've been able to
sync a single AD to multiple Azure tenants for years through trickery, but now it's an officially-supported replication topology. I'm seeing this having huge potential implications for GCCH, healthcare, education, and dev teams. GCCH can actually recycle custom domains between their commercial and gov tenants, too, so consider this the post-Christmas miracle you didn't know you needed. And and? Password hash syncing and writeback from any tenant is totally on the table, so you don't have to remember to go to Some Specific Environment to reset a password. And you can call Microsoft to complain when it misbehaves.
Remember when antivirus products made your computer slow? Apparently Norton was nostalgic for that experience, because
Norton 360 now includes a built-in crypto-miner. In a business decision as curious as NFT's, US Norton subscribers can opt in to leveraging their antivirus client to mine Ethereum. So you get to pay for the experience of slowing your computer down to raise your power bill. And you get to foot a 15% mining fee. Maybe Norton 360 is your jam, but if you're using it for business systems, maybe think twice before turning on all the features?
