I definitely tend to think of networking labs, of things meant for short term use & experimentation, but many of us really enjoy & rely on these systems serving our homes, our lives, reliably, consistently. I've heard some defenses of labs, but rarely is a lab doing the same reliable work again and again and again at a lab; labs feel like forerunners, not established bedrock.
Some day I really hope home servers cross the chasm, become more and more accepted & common. I know there's so many countervailing reasons, conveniences that keep this unlikely, but still I hope some folks find reason & find it not hard to back off from big cloud, to find advantage in running things ourselves.
There's the well known home-ops repo & folks. https://github.com/onedr0p/home-ops among techies I've seen some lightbulbs go off by calling the system a home-cloud. I'm curious what other nomenclature people have seen used, and how they feel it's been received?
I don't experiment much these days, so 'lab' isn't quite right. But if I were to experiment then it would be using the same hardware as all the other stuff. So it's both accurate and inaccurate.
In this instance: who cares, it gets the message across to the necessary demographic - and isn't that what communication is about?
...and I'm someone who could care less about words and grammar (notice the correct use of the term, so as not to say the literal opposite of what I'm trying to say (notice the correct use of the word literal, rather than it's not-oft-used-but-oft-correctly-applicable figurative)).
I don't know the (in)correctness of the use of brackets within brackets.
