A peeve of mine is when someone in the software industry denigrates a technology/tool/framework outside of his role eg webdevs on sysadmin stuff or viceversa.

I'm not trying to shame anyone for having subjective experiences, I just think that if you're gonna talk about tools that are not on your domain, then you need to be twice as humble as usual.

I'm a webdev and I don't post around how I KNOW how to make ssh secure, while other people devote their entire careers to that and all related matters.

What prompted me is seeing some not webdevs do this here that seem to be sysadmins/devops (can't tell for sure since I don't know them), but in real life, I've seen people from any role do this, webdevs too, even testers!

Imagine you had cancer, and you had a tumor extraction, and the oncologist said to the surgeon "step aside son, let me show you how to deal with cancer".
