I have some issue with how some of these are represented. For example, syncthing has an explicit opt-in request for telemetry / analytics. The suggested setting change is something entirely different - a call to ask what the latest version is. Granted, that server could log your IP address but that's no different to how it uses the relay and discovery servers that are also run by the same people - those could log the same way.
.. which is entirely different to the telemetry system where usage stats are reported. You can see that on data.syncthing.net. But again, thats a separate opt-in. The suggested env variable on the site won't turn that off.
Agile, as implemented in every big company that I've worked for, was a lie.
It was really telling at a smaller company that was trying to behave like a big company. I asked a coworker (who had great metrics) what the secret was for dealing with the middle-management-heavy and quite dysfunctional environment. He told me how he did it. Paraphrased: "It's easy. During each sprint, I work on the next sprint's work. Once it's complete I'll know how to make sure things match the work that's already been done and that way its always a bullseye and on time - because the work is already done.". Agile at that company was a joke to the people who got things done, and was a weapon used against people who didn't realise it in time. It sure generated a lot of metrics and stats though. I used to joke amongst coworkers that the company produced metrics, not products.
You are correct. This is widely copy/pasted bad advice and does the exact opposite of what the comment says.
It is not an idle timeout logout at all. Instead, it causes sshd to periodically send probes to the client. This has a couple of effects, most notably keeping tcp sessions "active" and frequently exchanging packets (this can be useful to keep connections through statefull firewalls alive if you are genuinely idle), and to rapidly detect and disconnect a client that has actually gone away.
I think the origin of this incorrect description is the CIS documents. They have the exact same gross mistake in them.
I think the ClientAlive probes are useful and should be on, but it's definitely not an "idle logout" as claimed.
