also tried the noacpi grub option, as per askubuntu.com/questions/1241795/…

secure boot mode is disabled, fast boot mode too, using AHCI mode, tried adding nomodeset in the grub menu, although the line is different than what I saw online: linux /casper/vmlinuz file=/cdrom/preseed/ubuntu.seed maybe-ubiquity quiet splash ---. Usually the --- are not there. Last time I added nomodeset right after splash, now I'll try after ---

the installation is on an Acer Nitro 5, gets stuck at "almost finished copying files" for over 40 minutes

I've managed to make a small server on my current machine to receive the logs, that I could make a pastebin from: pastebin.com/xHdncmHK

opened a terminal during installation process, and cat /var/log/syslog shows what I probably want to share, but how? wget and wifi is working just fine on that machine

towc

Jan 21, 2021 12:45

having ubuntu installation issues. Not sure how to extract logs from that machine so I can use them to get more help from another machine

thanks for taking the time, that's dedication to the community right there :)

well, install is still an argument

5 if you also send a 4 cheeses pizza to my address

towc

4 internet points to whoever figures out what I'm trying to achieve with that

towc

May 26, 2020 11:35

I guess at that point it's more like $\sum_{2}^{n-1} \left \lfloor{\left \lfloor{\frac{n}{x}}\right \rfloor - \frac{n}{x} + 1}\right \rfloor$

towc

May 26, 2020 11:26

you can also assume $n \in \mathbb{N}, n > 2$, for the sake of that problem

towc

May 26, 2020 11:23

$\int_{2}^{n-1} \left \lfloor{\left \lfloor{\frac{n}{\left \lfloor{x}\right \rfloor}}\right \rfloor - \frac{n}{\left \lfloor{x}\right \rfloor} + 1}\right \rfloor dx$

towc

@robjohn oh, right, I should have floored all the xs

towc

May 26, 2020 08:06

I don't think there's much variation to this formula that gives a neat integration

towc

May 26, 2020 08:04

the ultimate purpose is having something like $\int_{2}^{n-1} \left \lfloor{\left \lfloor{\frac{n}{x}}\right \rfloor - \frac{n}{x} + 1}\right \rfloor dx$, but easily integrable

towc

May 26, 2020 05:26

is it possible to elegantly integrate (c mod floor(x)) dx?

towc

great, doesn't support linux, but there's some scripts that can help: github.com/janten/dpt-rp1-py

seems like I might want to invest in this sony e-reader: amazon.com/Sony-DPT-RP1-13-Digital-Paper/dp/B072DXXXN1

I wonder if I can get a kindle or other non-harmful device to render it

towc

Mar 2, 2020 18:53

ok, this version sounds more fun: doc.lagout.org/science/0_Computer%20Science/3_Theory/…

towc

Mar 2, 2020 18:51

but I've definitely forgotten most of it :)

towc

Mar 2, 2020 18:50

I think I did all of this in highschool: mechanical.uonbi.ac.ke/sites/default/files/cae/engineering/…

towc

Mar 2, 2020 18:50

it does go a bit slow

towc

Mar 2, 2020 18:47

it seems pretty good: amazon.com/Schaums-Outline-Calculus-6th-Problems/dp/…

towc

Mar 2, 2020 18:45

I doubt something like this would exist that would cover as much ground as the MIT courses, but it's a start

towc

Mar 2, 2020 18:43

can you think of anything like that?

towc

Mar 2, 2020 18:43

this should be able to fit on my phone, with me spending most of my time scribbling notes on paper and feeling productive, right?

towc

Mar 2, 2020 18:42

ideally I'd find a textbook that makes you think most of the time, and after you've thought, the book tells you how a problem is conventionally approached, poses another problem, and repeats the process

towc

Mar 2, 2020 18:37

so I'm not sure what alternatives could fit my needs

towc

Mar 2, 2020 18:37

in highschool I couldn't focus on textbooks at all. I did 1 year of uni, on computer science, and all we needed were lectures, which are a format that works for me. But I don't like the idea of spending my free time watching videos

towc

Mar 2, 2020 18:35

but I'd also not enjoy carrying a book around

towc

Mar 2, 2020 18:35

I really dislike having to read from a phone, and I'd guess it's the main reason I don't keep going

towc

Mar 2, 2020 18:34

I have a couple textbook pdfs (mostly for development topics) on my phone, but I never finish them

towc

Mar 2, 2020 18:28

would I be better off buying a text book and going through it?

towc

Mar 2, 2020 18:26

is this a crazy thought? I'm a developer for a living, and I'm also trying to minimize screen time because I get too much of it from work, and my eyes can start hurting

towc

Mar 2, 2020 18:25

hey all, once again. I've started realizing I probably won't go back to university (given doggo, full time job, and living in slovakia), but also that I have a lot of free time I'm looking to fill up with things I find fun. So I thought it could be interesting to go over the lecture notes and exams of the various lectures from MIT, in order (disgarding outdated ones): ocw.mit.edu/courses/mathematics

towc

Dec 19, 2019 15:19

aren't you?

towc

Dec 19, 2019 12:55

the context seems to be related to ASTs

let me rephrase to "I think it's highly probable"

towc

Nov 11, 2019 10:58

I'm sure it's already on SE either way, but I have no clue how it would be worded

towc

Nov 11, 2019 10:57

curiosity. If this was for something more specific, I'd post a proper question

towc

Nov 11, 2019 10:56

it's not, but I hang out there, some of them are network-knowledgeable, so I thought I'd ask

towc

Nov 11, 2019 10:45

this is the link to the first room: chat.stackoverflow.com/transcript/message/47808156#47808156

towc

Nov 11, 2019 10:45

it's more useful as a conversation, I think. It's mostly a curiosity

towc

Nov 11, 2019 10:42

hey all, porting a question from another room:

if I have x.com and y.com, with two different applications running on port 443, can I host them from the same server?

simply pointing x/y.com to server and opening the applications on the same port won't work, because the applications can't both use the same port on the local machine

I'm sure this is possible, but not sure how

maybe a 3rd application running on 443 that looks at the address the clients are connected to, and acts as a proxy to other ports that those applications are running on? Can nginx or similar do that?
