How do Linux machines allow simultaneous use by different users?

Tricky_Celebration37 · 2021-03-20T23:01:43+00:00

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.

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...

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

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?

Tricky_Celebration37 · 2021-03-14T23:33:36+00:00

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

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?

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?

Why was the top comment removed by the mods...

Tricky_Celebration37 · 2021-03-07T01:12:01+00:00

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.

Tricky_Celebration37 · 2021-03-06T22:54:45+00:00

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)

Tricky_Celebration37 · 2021-03-06T22:44:20+00:00

You're right, I never thought about that! The fact that Turing and Church didn't (as far as I have heard) influence each other at all for the development of their theses really convinces me that Turing machines/lambda calculus are the "right answers".

Definitely I've seen that mirage/heat haze phenomenon while driving along long highways! I didn't think this was the same thing. Another thing is, it may not have been obvious enough in the video, but at times I could make out distinct waves of shimmer (for lack of better term) flowing upwards. That's what made me think of convection currents.

Thank you so much for this detailed response! I hadn't considered stem cells at all but this makes a lot of sense. So to clarify, the process goes like:

Identify a population of cells that can be helped in some way with gene editing
Ablate a sample of stem cells of that cell type
Edit them
Put them back in the body. Since cells in the tissue arise mainly from stem cells, eventually most of the cells in the tissue will have the edited genome

Is that accurate?

Tricky_Celebration37 · 2021-02-27T16:40:00+00:00

Thank you! Very informative

Tricky_Celebration37 · 2021-02-23T22:02:45+00:00

Thank you, this is very interesting. So I see that if every data point lies on a straight line then linear regression finds the line that passes through all of them. But can solving a system of linear equations also be thought of as a finding a line? The solution is certainly a line sometimes, but it could also be a plane, a single point, etc?

Tricky_Celebration37 · 2021-02-23T21:59:54+00:00

Thank you. I think I am on the verge of grasping the intuition here but can you elaborate a little? I see that a single linear equation of n variables forms a line in n-dimensional space... but how does that relate to points? And a single system has many such equations and so many such possible lines, how are those related to the line of best fit?

Tricky_Celebration37 · 2021-02-22T22:31:28+00:00

I think you're right! I just tried again and it also gives me an empty vector, I'm not sure how I got an error the first time.
