Well, as far as I’m concerned Skype for Business set the benchmark for terrible. Teams isn’t even close to being that level of bad

Teams is relative.

At a previous job (Microsoft shop but in the public sector so 10 years behind), the standard messenger when I started was Skype for Business.

In case you’ve never used Skype for Business, it’s “Skype” in branding only and actually has nothing to do with the Skype software that Microsoft purchased and is more like MSN Messenger.

Compared to that, Teams is a huge step up.

Also, at a Microsoft shop, you have to use what Microsoft provides even though it’s usually balls.

It’s 90% of the reason I now refuse to work anywhere that’s bought into the Microsoft ecosystem. It’s just so… mediocre

SELinux is one of the first things I disable. It causes way more problems than it solves.

All my workloads are containerised so I’ll trust the security of that machinery to sandbox them instead

Just think of it as a routing optimisation that is only relevant for ipv4 networks.

Router simple, router need to make decisions quick, quickest decision is made when can smush the subnet mask against an IP address and determine if the computer is on a local network so router can send traffic direct or is on other network so router needs to send traffic to other router
