Hmm, what does he mean "I woke up the next day"? Did he leave Factorio running, or did it get an online component while I wasn't looking?

Probably left it running? I've definitely left my factory to idle to build up resources while I'm gone, when I'm playing on peaceful mode. You could also run headless version of the game on a server and just connect to it for the same effect. Remember - Factorio is just an idle game with extra steps.

Ah, makes sense, thanks.

It's done by some people intentionally to be offensive, and it's impossible to tell if someone doing it is doing it as an insult or out of ignorance. And, believe it or not, there's enough people out there that do it intentionally that assuming ignorance would be incorrect more often than it'd be correct

One reply tweet notes "a complex system always operates in a failure state", but to find more discussion on this point it's worth noting that this is a restatement of: > "The Fundamental Failure-Mode Theorem (F.F.T.): complex systems usually operate in a failure mode." -- John Gall, General Systemantics (aka Systemantics , aka The Systems Bible ), 1977 https://en.wikipedia.org/wiki/Systemantics > Searching for "funda…

'complex systems usually operate in a failure mode' has a somewhat different meaning from "complex system always operates in a failure state".

They usually operate in a failure mode because it's easy to be deceived by the superficial appearances of complex systems, thus it seems like a big bother to drill down the layers, until a failure has occurred. As excellently demonstrated by this 'Factorio' player.

What drama with the Factorio devs is he talking about at the end (and namesearchers?.. I don't get Twitter sometimes) I've never heard anyone say anything about the Factorio devs except praise their productivity and professionalism.

One dev said in one post that they like Uncle Bob.

I think that’s it.

Great article, made this exact same mistake in space exploration before learning to transmit demand and not supply. There are so many principles like this I learned from playing through the game. One area I've been focusing on improving is trying to anticipate how any given subsystem might go wrong and add even simple circuitry to detect condition and alarm/signal to the factory dashboard. Has cut down on the times where I realize some part of factory hasn't been working properly for like 5 hours. Applying this to software development has made me better about getting better about how I use rollbar logging
