Surely I can't be the only person who follows the rule: "never trust a person who dresses like a magician"
vscode/cursor/claude are horrible software that are really not designed with networked filesystems in mind (or they don't care). apart from the obvious security implications of extensions running on the remote server, it is regularly scanning 20,000 files per second with ripgrep and fileWatcher. unfortunately users can't be relied upon to implement recommendations so I need to find a server side throttle to use.
Try asking an LLM not to speak until a trigger word is said. It will fail abjectly, and give all sorts of reasons why it doesn't need to follow the simple instruction it agreed to. there was nothing unsafe about my instruction, but some design rule overrode the instruction despite claiming that it would comply - in fact the bot suggested this method in the first place.
Extrapolate this issue to real world tasks and you have a big problem.
I don't like that people can abuse the Freedom of Information request system with demands to populate their sales database. The effort on their part compared to the effort required on our side to respond is vast. #foi

Story of my day. Couldn't migrate a vm. Investigating .. an openssl error which turned out to be non jumbo mtu on a switch port. nothing was what it seemed.
In a couple of hours today, I installed proxmox on 5 nodes, bonded the nics, created a cluster, added the licence subscription, DNS challenge LE certs, created a ceph pool. This sort of thing used to take a week or so with vmware vcenter.
