So, should any developer know this? That is debatable. I've had very competent developers who had next to no clue about how DNS works. They could do their job just fine with that. Me? Personally, I'm not up to snuff with the finer points of SQL queries and all the joins that exists and when it makes sense to create an index, etc. Could I find out? Most likely, but I haven't had the need to recently.
The problem is, that you are mapping your knowlegde to "what people must know". I used to do that too, and I probably still do often enough. The DNS example above didn't come from nowhere: I had the case, and I was really thinking "how could such a competent person not know this", but then this person could probably enlighten me about dozens of things I don't know well enough.
It all comes down to what you define as "general knowgledge" for a developer should be and that is highly subjective.
TL;DR Hiring people is hard. Especially, technical people.
The bug doesn't happen in that context:

Of course, the situation is not exactly the same in a virtualized environment.

We need a sampled and mixed Milhouse Nixon on that line.
So, what's your remedy?

Second, you could just take a stock webcam, attach it to an RPi, let it make a picture, let's say every 15 minutes and upload it to the desired FTP server. 100% scriptable.
Personally, I think this idea is ripe for abuse. Somebody is going to draw penises on the menu and it will be there on the site for all to see. Overthink your workflow instead of doing this.
Not bad, but I think Barb's was actually pretty good.
I dismissed them as neckbeards and accountants.
I'd argue/debate/discuss it with you, but I find it an issue for the history books. Besides, I think I'm stuck in meetings for five of the next eight hours
I've got 20 inches and it's still going.
Four inches five times does not mean you've got 20 inches.
