You don’t have classified documents, but you probably use bank in your browser running as your user. Maybe you use local mail program to send emails, also running as your user. A simple malware could add emails to be send asking your family to send you some money through online service.

And that’s easily done because the only isolation layer is user and group.

Are you saying that AI slop is bad in those (counts) 4 removed lines of code?

Downsizing. If you don’t need to run or keep stuff, then you don’t need so many servers and storage. You may run stuff on cheap mini-pcs.

Sleep: In my experience sleep sucks, I’ve spent long hours planning around sleep in homelab, like: when do I restart, do updates, when do I upload backups. I have Pi and at some point I realised some actions on Pi need my sleeping NAS… so I dropped all the sleep and now it works 24/7.

Explain to your manager that if an employee can merge code without reviews, he should expect breakages on regular basis.

Propose that your team can meet to talk about how to make the process better, so no breakages occur.

Mention personal responsibility and knowledge - it’s a good practice that a person who wrote the latest code changes either helps either is responsible for making the service working again, if there are issues - specifically because they might have some idea what’s broken.

If your manager will ignore it, I’d start looking.

I’m not sure you’ll get nice performance in local network with small appliances (consumer network hardware, mini PCs and rpi 4). I’ve never got sub-ms network disk access on 1Gbps switch and router. In the end I’ve done the opposite - I’ve added one k8s host with a lot of storage, and any storage services are deployed there. All the other k8s services rely on local SSDs.
