Map makers make mistakes on purpose. This way they know when someone copies their maps. They look for these little tiny "mistakes".
Never happens on the Apple Maps, although I have 0 trust in siri and apple maps, especially when we travel to europe, i feel like i'm an experiment for apple to see how much off straight forward route it can make me take.

He won’t. And those that went along with him will be judged poorly by it.
"least impractical"?
Unintentional double negative, I think?
Currently it conveys the meaning of being "most practical" whereas it was the opposite.
And the prose itself is good too.
Early in the pandemic my job wrapped up, and when I went looking for a new part-time or contract gig, there was absolutely nothing. I networked and searched for a year and a half, and never found a single part-time opening. In the meantime, donations to the site were on a steady downward trajectory. I was burning through my savings at an alarming rate.
Eventually I had to take a regular full-time job just to have income again. I hoped I could find some plausible approach, but so far it's been unworkable. I also have a six year old, so evenings and weekends tend to be spoken for. And after the little one's bedtime, there's not much left in the fuel tanks. I'm approaching 50 now.
Maybe I'll find a part-time gig, or perhaps some anonymous wealthy benefactor will fund the site for a while. Both have happened before. If not, we may need to pack it up soon. 20 years is a pretty good run.

The missile knows where it is at all times. It knows this because it knows where it isn't. By subtracting where it is from where it isn't, or where it isn't from where it is (whichever is greater), it obtains a difference, or deviation. The guidance subsystem uses deviations to generate corrective commands to drive the missile from a position where it is to a position where it isn't, and arriving at a position where it wasn't, it now is. Consequently, the position where it is, is now the position that it wasn't, and it follows that the position that it was, is now the position that it isn't.
In the event that the position that it is in is not the position that it wasn't, the system has acquired a variation, the variation being the difference between where the missile is, and where it wasn't. If variation is considered to be a significant factor, it too may be corrected by the GEA. However, the missile must also know where it was. The missile guidance computer scenario works as follows. Because a variation has modified some of the information the missile has obtained, it is not sure just where it is. However, it is sure where it isn't, within reason, and it knows where it was. It now subtracts where it should be from where it wasn't, or vice-versa, and by differentiating this from the algebraic sum of where it shouldn't be, and where it was, it is able to obtain the deviation and its variation, which is called error.

And for HN in particular, there is an ancestral link from the suffering crew of the ill-fated ship to the category of jobs that we have today.
I won't spoil it. But here is a clue: A.L.
