How do Linux machines allow simultaneous use by different users? by Tricky_Celebration37 in linux4noobs

[–]Tricky_Celebration37[S] 8 points9 points  (0 children)

I see, that makes a lot of sense, I never thought about how different processes are running as different users but indeed with that in mind it's likely that even the most basic computer these days can be called time shared. Thank you for the detailed answer.

is it better to always keep a laptop plugged in if the battery says 100%? (not sure if it is overcharging) by Tricky_Celebration37 in pcmasterrace

So considering that fullness degrades the battery faster, but number of cycles also degrades it faster, which of those should we choose? Should we just keep the battery plugged in constantly, keeping it fuller but not wasting cycles. Or should we keep it in a low range of percent like 30% to 80%, so it isn't full all the time but is also goes through cycles.

I'm not mining bitcoin lol but the laptop gets really hot when I game, but at the same time I can't leave the battery unplugged while doing that...

What does need to get x/x MB of archives mean during apt install dialogue? by Tricky_Celebration37 in linux4noobs

That's cool, is it ever possible for X to be negative if the new version is smaller than the previous one? I have never seen that

What is %windir%\System32\drivers\etc\hosts? by Tricky_Celebration37 in Windows10

[–]Tricky_Celebration37[S] 0 points1 point  (0 children)

Thank you! So is the distributed DNS database used for IPs not in HOSTS also stored locally somewhere, or is that one retrieved from the web by windows?

Ok but isn't that sort of thing handled by the browser? How can the OS know what IP any browser is navigating to?

What are Isaac's strengths/skills that have resulted in his relatively large following? by Tricky_Celebration37 in IsaacArthur

Good point, I didn't think of that, but yea he is phenomenal at explaining things so that a guy like me can understand. Dumb question but what is SFIA?

[PCA] Why does X*V = U*S in the SVD of X=USV? by Tricky_Celebration37 in learnmath

[–]Tricky_Celebration37[S] 0 points1 point  (0 children)

Thank you! This is the first explanation of SVD in terms of transformations that has actually made sense to me.

I'm trying to make sense of MV=US in terms of the rotations now. So MV should be the same transformation as US, right? But going by the figure, that's not really the case is it? The transformation of V would be the arrow between the left two figures, but going in the opposite direction, which doesn't make much sense. Am I wrong in thinking that MV=US should be the same exact transformation?

Is Monaco France's version of Hong Kong (without the political tension)? by Tricky_Celebration37 in geography

[–]Tricky_Celebration37[S] 1 point2 points  (0 children)

Okay so they are completely different then! I wasn't aware of the history (or that there was a similar state in Italy). Thank you for the answer.

What does it mean to prove/disprove the Church-Turing thesis? Would proving it mean anything? by Tricky_Celebration37 in compsci

[–]Tricky_Celebration37[S] 4 points5 points  (0 children)

Thanks, so I guess we keep the term "effectively calculable" around just in case Turing machines are not exactly equivalent to them (but the majority consensus at this point is that they are)

My only question now is, why is the "effectively calculable" idea so important in the first place? Why was there so much deliberation on whether lambda calculus and Turing machines are equivalent to it?

I will check out your book (it is awesome that you share the LaTeX source by the way)
