  • My biggest problem with The Matrix is where the machines are getting the food from to feed the humans. You need a continuous supply of food to support continuous energy conversion; that energy isn’t being created from nothing. Normally that comes from the sun photosynthesizing plants (which then works its way up the food chain), but with no sunlight then plants can’t grow. They say they feed the liquified remains of dead humans to the living ones, but even if digestion were 100% efficient (which it definitely isn’t), the amount of usable “food” would constantly decrease until there’s nothing left.



  • There was a thread about that on c/selfhosted a few weeks ago. Created by a particular wild-cat-inspired sysadmin, I might add.

    But on a more serious note, the interactions between a sysadmin and their servers (that they have enough responsibility for to be able to name) are much more intimate than the interactions between a dev and their variables. The server names also exist in a much larger namespace, so they need to be more unique.





  • Pi-hole works by giving clients non-routable addresses in response to DNS queries of known ad-serving domains. If the client (web browser, phone, smart device, etc) doesn’t let you set its DNS server (as many no longer do) and doesn’t obey DHCP, then you can’t feed them those addresses. You could block outbound DNS traffic from all clients except your Pi-hole, but in response some clients will just refuse to work entirely. And if they require DNSSEC (or DoT/DoH with a pinned certificate), there’s nothing you can do.
