Funny to see this today. I had moved a repo from an old Mac laptop to linux months ago, and git couldn’t find the ref to HEAD, because HEAD was pointing to the case insensitive branch name, and it didn’t match the case of the branch. Manually edited HEAD to the correct case to fix it. I should probably recreate the repo for good measure…

Are you using docker compose? You can set the container hostname for telegraf, https://community.influxdata.com/t/incorrect-hostname-picked-up-by-telegraf-docker-container/24469/6

Not directly to your exact question, but do you have something like rspamd set up? I would consider doing some filtering with rspamd modules. It’s a lot of learning to go through, but has some good defaults. It can filter outgoing mail as well as incoming.

Reminds me of LEDs used to extract data out of airgapped networks: https://threatpost.com/blinking-router-leds-leak-data-from-air-gapped-networks/126199/ but different because that one requires software within the airgapped network to exfiltrate.

Didn’t there used to be network equipment that was vulnerable to data exfil from data status lights, or did I dream that up? Most data LEDs now just consistently blink.

Slacks problem isn’t with generating things to say, it’s with managing attention spans and navigating between conversations easily. If the integration can help with that, maybe it will make sense. But if it just helps people write, that is nice but I’d be concerned that it would lead to longer and less direct messaging.

Should be able to handle a few users OK. You might want a more permanent server to run it on if they want to keep using it long term though.
