study-discussion

[fleet hill]

Hey all, this is a pilot of the #study-discussion channel, for the purpose of discussing study strategies, common obstacles, preparing for exams, how to self-study math, etc.

[coral sleet]

oh

[fleet hill]

I've opened it for now to people with specific roles (Honorable, Helpful, Very Active) for the pilot, but the intention is to open it soon to everyone, once the tone of the channel is set.

I'll start us off with a question! How do y'all tend to take notes during math lectures?

Personally I tend not to take notes because I feel like following along with full focus is more helpful, but I've noticed people have a lot of different strategies

[coral sleet]

write down everything the prof writes down, plus anything remarks I think are relevant or useful to know

[hoary kindle]

I dont, I think it just distracts from listening to what the lecturer is saying.

Uness it's a talk or something where I couldnt have done the reading before hand, but even then I typically just take down some interesting remarks or ways of looking at the problem

[coral sleet]

I want to try to write a lot less next year though. I've come to notice that I lose track of the lecture quite fast if I'm trying to keep up with the pace sometimes

I think it'll be more productive to try writing only key ideas down, instead of everything

[fleet hill]

Hmm I guess it's kinda tricky with math though because if you write down the important theorem without any of the context you might not be able to tell afterwards what the theorem even means...

[coral sleet]

key definitions, ideas in proofs, etc

[hoary kindle]

and very rarely if ever have I went back to look at notes ive taken for anything besides an interesting remark, so theres also that

[coral sleet]

but not all the dirty details

[hoary kindle]

The context is what I like to take

I can find the theorems carefully stated in the textbook or the paper if thats what I need, the context and lecturers perspective I cannot

[hybrid walrus]

i take notes on a tablet, depending on the lecture i either take everything, just big ideas, or nothing. i find that lectures where i take nothing i remember the least and lectures where i take everything i process the most.
i hear a lot of people say that taking all notes distracts them from the lecture, so often what i do is i make lots of space for myself to go back later and create notes for myself explaining the details of what's happening. so my notetaking is really focused on mechanically copying the essentials of what is written rather than trying to interpret or get every detail, then later i can go back and process and expand a bit for myself.
i need to take notes to keep myself attentive to a lecture, otherwise my attention will drift and i'll space out.

[fleet hill]

Hmm there are some classes where I will write down everything that's written on the blackboard, but that's only if the prof doesn't post any notes and there's no textbook

I hate those classes

[fleet hill]

What app do you use to take the notes? Just curious

[viral osprey]

I just always write everything down. I do this because if I don't I'll zone out. I also rarely ever reread these notes unless there are no other resources to use.

[coral sleet]

I've never actually gone back to reread my notes

do people write notes with the intention of using them later to study?

[viral osprey]

I have but I prefer not to. I'm not really making notes to reread so much as to process what I'm hearing.

[hybrid walrus]

notein

[viral osprey]

For my algebra prelim I was told that we were going to be tested on what we covered in the class and what we covered in class was based off of notes our prof used that was based off of notes he got from another professor which was based off of df I think?

It was a weird situation, so I actually ended up following those notes pretty carefully.

[hybrid walrus]

yeah same on the rereading and studying. very rarely do i reread, the filling in blanks i mention happens right after lecture or even sometimes during a lull in a lecture

[viral osprey]

I "reread" other things besides my own notes lol

[fleet hill]

I do for classes where the prof doesn't post any notes, otherwise I literally have nothing to study off of

[viral osprey]

Usually I'll rewrite key definitions, theorems, proofs etc in a nice pretty packet. That's sort of how I reread/review things.

[hoary kindle]

That sounds like a horrid course to take, im praying I never run into this lol

[quaint viper]

most of the courses i have encountered are like this

there is always a textbook of sorts, so strictly speaking you still don’t need to take notes if you don’t want to

[hoary kindle]

I have a slightly unhinged approach to this, i like to make these slightly horrid looking dense sheers with the important points of the course condensed into a couple of pages

[finite bane]

I used to take notes for a few classes, but then I just ended up with like 38 pages used up and nothing learnt

[coral sleet]

I don't think I've ever learned much during the note-taking process

[hoary kindle]

This is an end of semester pre exam review technique though. Mid semester I read notes before the lectures, go to the lecture (sometimes, oops), then usually reread the chapter of the notes again while doing that weeks homework

[coral sleet]

it's always afterwards when I go over the material again and/or do problems that I find myself learning

[viral osprey]

Make it prettier, don't be cringe.

[hoary kindle]

The density works for me, it is a concious choice

[viral osprey]

I'm only kidding

[hoary kindle]

I print them out and pour over it, but its really the process of making them that I feel helps pre exam

its nice to redo everything with the full context of the course

[viral osprey]

I think this is effectively the same thing I do as well except more dense and in a different format.

I can see a tradeoff here that might be good for certain types of review

[hoary kindle]

I have a horrid attention span and I feel like I actually just end up reading more when I have a wall of text, potentially a very me thing but it seems to work

[finite bane]

i dont think i can physically read a huge wall of text anymore

like, my eyes always move somewhere else for a split second and i lose where i was 😔

[heavy rock]

🔥

[neon topaz]

Question, regarding note-taking (for those who do take notes): do you later read said notes, at home for instance?
Why am I asking this? I've never done that; the fact of writing the stuff was typically enough for me to remember it, and studying was done through exercises

[fleet hill]

For classes where the profs didn't post notes, I def read the notes later while doing the exercises because otherwise I would have no way to find the definitions, theorem statements, etc. (or at least the versions that we covered in class)

[olive geode]

I never take notes during lectures, because I feel like it distracts me from thinking about what the lecturer is saying. It's not a goal for me to remember everything that is said anyways, as long as I can remember the overall vibes and ideas, then I can look up details in a book or something later

I sometimes take notes in Obsidian when I figure something out that isn't explicitly spelled out in a book, but I rarely look over these notes later

[coral sleet]

no, and I write notes for the same reason

it just helps me recall things a bit better later on, when I need to solve problems

[viral osprey]

My note-taking technique is like screaming into the void

[rocky terrace]

I have slowly refrained from taking notes as well, when I'm going through a textbook that is

I just learn the material, then I do the relevant exercises

I used to take a bunch of notes, then I realized I was literally just writing the exact same thing in the book, (basically word for word ) So I just stopped taking notes while self studying

[rocky terrace]

But in lectures... I'm not sure, I haven't attended many good lectures, but I usually find that I struggle to pay attention to the lecturer if I am too intent on note taking, or I struggle to take notes if I am paying too much attention to the lecturer, especially if the lecturer is going at a fast pace

[rocky terrace]

I always tell myself that I'm going to, but I never do

[finite bane]

i tried doing digital notes

like a few months ago

they did NOT work

i think i ended up deleting em since they were taking up onedrive space

onenote is alright as a notes app

but it's just so grating to look at

[torn olive]

I do digital notes but they're handwritten still

Which I love

[finite bane]

do u use a drawing tablet?

or like, a stylus + trackpad on a laptop

[torn olive]

I have an iPad

Which yes is expensive but honestly worth its weight in gold as far as I'm concerned

With how much I use it

It's all I take notes on, I annotate PDFs on it, I read on it, I sketch out homework and other computations on it

Essential to me

[dire eagle]

As others similarly remarked, i think taking notes can just be a distraction from digesting the lecture ideas, i rather try to engage and be interactive while only noting down very important remarks, and only after the lecture will i try to write down notes from memory. Luckily it helps that i always had classmates who do write more detailed notes in class, which i can use as a reference haha.

[rocky terrace]

Also

books

[dire eagle]

One thing im trying to actively be better at is actually writing notes for myself, i feel like often i end up writing notes as if i'm trying to explain a idea to someone else, or in a way thats understandable for others, when i can be more efficient and try to just remind myself on the topics. Its kinda good practice on formal and clear writing but i definitely overdo it.

[viral osprey]

I'm gonna write about how silly all of you are in my notes.

[elfin oasis]

i dont learn much in lectures that involve notetaking on my own

[pale hedge]

I did this, realized I was copying the book, then continued, since I was writing more explanation when they skipped over a step, and since it had become habit

[main trail]

New channel?

[main trail]

I just solve the problems we do in class

I pay attention and then read the textbooks post-class

Another question. Do y'all take notes in humanties classes? Or pay attention and just read the precribed texts later?

[fleet hill]

Most of the humanities classes I took involved discussion, so it was more talking than taking notes for the most part

[main trail]

Fair

In my humanties classes, there are a lot of discussions, but they mostly allign with my interpretation of the texts, so my notes tend to be rather terse

Like this sem I took a course on anthroplogical theory and one on critical reading

[dire eagle]

https://youtu.be/9qlqVEUgdgo

What a great vid, credits to @rocky terrace for sharing, pin worthy imo.

[rocky terrace]

real credits to Brandon

it seems Emeritus roles can't access this channel, so sadly I can't ping him

[eager halo]

I agree with this, for me.

I feel like writing notes during lecture distracts me too much; it just ends up being the worst of both worlds for me.

[safe harbor]

Stucussion

I like taking notes, and making them pretty. Im quite quick with it, which comes from a few years of experience. I find that it helps me remember the material better

But I understand why it doesn't work for everyone

[silent tangle]

the same is true for me. i almost never read my notes while i was in college, except for when compiling them for open-note tests and such

[torn olive]

I take notes to force me to pay attention

[chrome wharf]

I took very detailed notes while I was taking my grad algebra class and I mainly relied on those because there wasn't a book we were following for that class

[scenic shuttle]

new channel!

i’m wondering how do you guys take self notes in cs other than documentation

i use latex but it’s too much work, any other methods

[steady cliff]

Whenever I try to make notes I just start drawing spirals instead

I mean in high school most of the stuff is just from the book so it isn't that necessary to take notes

[main trail]

don't

just see slidess

[scenic shuttle]

the slides are literally generated by ai

they’re too much to read and less information

this is how i self-study the lectures

[olive geode]

Are those the slides or is it your own notes?

[scenic shuttle]

my own

the actual lectures they give aren’t that useful

like i said very ai generated ngl

[main trail]

Holy moly

[olive geode]

I don't have any suggestions on how to take notes for cs, but I hope you don't try to memorize those validation regexes 💀

[scenic shuttle]

[winter nebula]

lets goooo finally a self study channel

[whole wing]

Can't think without writing. So I usually write all the calculations adding in the details I had to figure out
Will also highlight tricks and insights

[fleet hill]

Ah interesting, I feel like it's harder for me to think while writing, but writing it out afterwards for homework helps me internalize things (usually I realize there's things I thought I understood but don't).

[woeful yarrow]

anyone from luxembourg here?if so can anyone show me how 11 grade math looks like there?im kind afraid it will be harder than in my country

[olive geode]

You've written this in latex, right? Maybe a stupid suggestion, but since it's mostly code, how about just writing it in javascript files, using comments for explanations? That way you could read it in an IDE, get type hints etc. and it's easier to modify and run the code to see what it does

[scenic shuttle]

yes i did write this in latex but i sometimes need read their lectures because they give us multiple choice questions and also it’s helpful for diagrams

i do this but it’s too much and hard to open in other devices like my phone or ipad

so i write them in latex to easy review the stuff

[olive geode]

I see. I think learning coding this way sucks, because being able to answer multiple choice questions is so different to being able to actually code. I mean not the way you're learning, just how these courses are set up in general

you're kinda forced to memorize things, instead of just building stuff and playing around with programming

[scenic shuttle]

they give us exercises so I get a chance to practice those

sometimes they're useless

[cobalt sun]

yeah

[scenic shuttle]

I feel like the next half of js is lowkey cooked

dom, event handler, forms and node.js

I have an exam about these topics tomorrow and I feel like I'm not getting this shit yet cause professor is replaced by ai and pretends she knows about it. what should I do? I've finished the practice but I don't feel like anything lmao

[silent apex]

oooh

this is new

[glacial raven]

yeah, channel was created 2 days ago.

[silent apex]

its good

[reef ocean]

maybe some sort of interactive notebook is better to take coding notes? I don't have any particular suggestions just throwing the idea out there

[narrow quail]

email validation doesn't even look correct

[olive geode]

I think it's good enough, it basically matches any string with no whitespace containing exactly one @ followed by atleast one dot. It'll match strings that aren't email addresses, but email addresses can be so complicated that you shouldn't try to match it with regex anyways

[narrow quail]

Just match on \S+@\S+

🙂

[unreal mulch]

For me, I usually take notes in Jupyter notebooks which supports C, R, Python, JS, etc. Beside that, I sometimes make a small project based on the things I've learned in the course, with some comments on my own code.

Although some of my CS classes are syntax- and language- agnostic, so I sometimes write pseudocode as well.

[scenic shuttle]

i’m familiar with jupyter notebooks but i didn’t know you could use any language like js

i thought it’s only for python

[narrow quail]

write one in js 🙂

[unreal mulch]

As long as you have the kernel it's usable

[cobalt sun]

that JS course when they find out about <input type="submit"> and html form validation

[unreal mulch]

What about

^(?:(?:[a-zA-Z0-9!#$%&'*+/=?^_`{|}~-]+(?:\.[a-zA-Z0-9!#$%&'*+/=?^_`{|}~-]+)*
|"(?:[\x01-\x08\x0B\x0C\x0E-\x1F\x21\x23-\x5B\x5D-\x7F]

(?:[a-zA-Z0-9-]{0,61}[a-zA-Z0-9])?(?:\.[a-zA-Z0-9]
(?:[a-zA-Z0-9-]{0,61}[a-zA-Z0-9])?)*|\[(?:(?:(?:25[0-5]

|[01]?\d?\d)|IPv6:(?:[A-Fa-f0-9]{1,4}(?::[A-Fa-f0-9]{1,4}){7}))\])$

[cobalt sun]

what does this even match

[scenic shuttle]

noted

[cobalt sun]

oh it's a URI

oh yeah i made a regex like that once LMAO

a few years ago

[scenic shuttle]

how did you make this

[cobalt sun]

it took me a whole day LOL

[scenic shuttle]

[unreal mulch]

Almost RFC 5322 compliance regex for email matching

[cobalt sun]

the longest regex i've used recently is a thing matching a valid JS import statement

[cobalt sun]

"almost"

[unreal mulch]

You can find things like https://github.com/brendan-rius/jupyter-c-kernel online

[unreal mulch]

Yeah, unfortunately.

[cobalt sun]

what's the edge case?

[unreal mulch]

I don't think the total thing is suitable for my use cases

[scenic shuttle]

i can use vscode

[unreal mulch]

RegEx can't match recursive patterns

[unreal mulch]

Yeah it works with VSC as well

[cobalt sun]

there are a few regex engines that support this actually

i think perl can do it

[rocky terrace]

Regex also cant match HTML

[cobalt sun]

it can with recursive tho

i mean

[unreal mulch]

That'd be considered extended regex yeah

[cobalt sun]

there is my regex matching a valid HTML tag

(chatgpt's)

[rocky terrace]

https://stackoverflow.com/a/1732454/13869439

[cobalt sun]

LLM's are suprisingly good at making regexes tbh

[scenic shuttle]

it’s my last day as doing js(read my status) so i might use other languages with this kernel especially py and julia

[unreal mulch]

It's really unfortunately that RegEx can only match regular languages

[unreal mulch]

Yeah, iirc Haskell is also usable, let me check

Yeah there's iHaskell for jupyter stuff

[scenic shuttle]

i’m not sure if i’ll go back learning haskell

[rocky terrace]

Haskell rotated counterclockwise by 90 degrees

[scenic shuttle]

worth it? idk

[unreal mulch]

I've also been enjoying Idris as well, in my opinion, 'functional programming' languages are really good to know if you study CS.

[steep birch]

ew what is this

[rocky terrace]

C++ is my favorite functional programming language

[cobalt sun]

what's idris?

[rocky terrace]

it's also my favorite dysfunctional programming language

[cobalt sun]

C is my favorite OOP language

[unreal mulch]

It's like, Haskell but with strict evaluation (optional lazy too), and dependent types.

[cobalt sun]

ah so actual FP

[unreal mulch]

It's also built on QTT (quantitative type theory)

[cobalt sun]

oh no another type theory variant

ok this is getting off topic lets go to discussion

[unreal mulch]

As for side effects, Idris leans more on algebraic effects while haskell uses monads

[short dirge]

every channel is #cs-discussion fr

[unreal mulch]

Oh sorry.

[scenic shuttle]

can we go back to js in dms

[cobalt sun]

oh i gtg in a min 😭 sorry

[jolly quiver]

Oh hey new channel

[main trail]

damn it

[random tusk]

woah a new one, good channel premise

[safe harbor]

Get better at LaTeX

Just use it a lot

And you'll get quick enough

Oh you said CS, well for TCS LaTeX is good. For practical stuff I just pray to god

[storm jasper]

Let’s gooo it released

[mental cairn]

Snippet stuff!

[scenic shuttle]

I'm already better at latex but it takes some a lot of time

[scenic shuttle]

what's this

and where to use

[mental cairn]

This is one of the things that helped me shave a LOT of time typesetting. Template a bunch of what you commonly use and just store them as snippets in for example vscode

For example, I have snippets for a basic table, plot, floats, etc. That i just use everywhere and modify according to what I need

[scenic shuttle]

ah

I once had this installed but I deleted it

cause overleaf is good for this

[mental cairn]

Had what installed?

[scenic shuttle]

latex stuff in vscode

[mental cairn]

VScode is pretty okay for most of what you would need. Although I wouldn't really recommend using the LaTeX workshop extension

Also, you can also write a python script to generate your latex project

[scenic shuttle]

I see

[rocky terrace]

yea I just use Overleaf

I haven't really needed anything beyond what Overleaf provides

I open it up, I type proof in LaTeX, I happy

[mental cairn]

you hit their compilation time's limit quite fast if you are writing something big though

[rocky terrace]

oh yeah if you're writing something like a book or article that would be a problem

and you'd need to buy premium

and money doesn't grow on trees

so I should set up VS Code LaTeX extensions some time

[mental cairn]

Never really understood why people don't just run it locally, unless you have a really bad PC or something

[rocky terrace]

I think it's just because most people aren't writing large stuff

[scenic shuttle]

I've used to write huge latex stuff in hs and it was so laggy

so I have to make it parts cause I don't have premium

[rocky terrace]

the huge latex stuff in question:

\Huge

[scenic shuttle]

real

[mental cairn]

the extensions are really annoying from my experience. You are better off running it from the CLI using latexmk in my opinion but to each their own

[rocky terrace]

but muh linter

[mental cairn]

the linter seriously was starting to give me an aneurysm

linting and latex just dont go well together istg

Anyways Latex can get very unproductive and there is no helping with that. I wish there were better WYSIWYG alternatives

typst i heard is getting there

but idk

[unreal mulch]

Have you tried https://www.lyx.org/ ? Somebody here recommended it to me some weeks ago and I've found it to be quite good

[scenic shuttle]

I should give it a try

thanks

[fleet hill]

is that more convenient than using overleaf? overleaf is free anyways and the cloud storage is nice

[wheat ether]

overleaf gets really slow for me passed a certain document length

[mental cairn]

Well the aforementioned limits imposed on you by Overleaf are an issue. Plus, it can get really slow from my experience. Also I just generally dislike their UI; I find it clunky and not really suitable for long-term editing

[mental cairn]

I have heard of it but I should maybe give it a deeper look

[fleet hill]

Hm the speed hasn't bothered me

It also now gives you a little instant popup whenever your cursor is in a display mode thing, which is pretty convenient

[mental cairn]

Oh but if what I am working on is meant to be collaborative in nature I tend to use Overleaf

I haven't really found a better alternative, but im sure there are some vscode extensions for real-time collaboration I dont know about

[mental cairn]

Thats neat

[scenic shuttle]

why I feel like I've seen you before

or could be someone else

[mental cairn]

probably a random coincidence

[onyx sluice]

hello everyone

i need some help

[scenic shuttle]

[scenic shuttle]

yeah sorry they’re deleted user now #latex-help message

[onyx sluice]

i need a book or anything of linear algebra i have a homework about system of cramer and i have some questions

[mental cairn]

Is this your first or second semester doing linear algebra

I.e., is what you are doing purely computations?

[rocky terrace]

Introduction to Linear Algebra by Gilbert Strang

also

https://www.youtube.com/playlist?list=PLZHQObOWTQDPD3MizzM2xVFitgF8hE_ab

this will be quite helpful in developing geometric intuition about linear algebra

[onyx sluice]

first

[onyx sluice]

thnx !

[torn olive]

I like my fancy editor shortcuts

[fleet hill]

fair lol

[drifting crystal]

Do you use emacs? For some reason I get emacs vibes from you

[torn olive]

Doom Emacs specifically

Real question is if I want to be giving off Emacs vibes

[queen stag]

Holy shit 😭😭😭

Amazing

[shell glade]

i don’t really take notes, often because the lectures are following a specific book

not in college for math yet, so i usually just use books for everything and richard borcherds

[shell glade]

my computer doesn’t seem that much faster than overleaf in compilation, but snippets and vimtex make it so

[sick grotto]

I'd definitely write down everything that is on the board, the motivation and remarks the professor just mentions I wouldn't and would just keep in mind

[fleet hill]

hey serge! how's it going

when do you go to college?

[vernal grail]

Latex

🙂

[vernal grail]

Very true

https://github.com/SelahW/nvim

[hoary kindle]

Infinitelty. Overleaf is down all the time, I dont always have internet, I have a shit load of shortcuts in VSCode, I can run terminals right there, I have a PDF viewer, I have a spell and grammar check (which is better than overleafs), etc.

The only things id give overleaf is that you can share documents easily and clicking on the PDF to jump to that part of the code is nice

[fleet hill]

huh I've never experienced overleaf being down

overleaf's spellcheck sucks tho

[hoary kindle]

Perhaps all the time is an exaggeration, but its certainly not uncommon, Ive heard people complain about it a non-negligible number of times

I dont want my ability to do work to be tied to some random service running if I can help it

[vernal grail]

vimtex has this

[hoary kindle]

I think latex-workshop on VSCode is supposed to have it, but it doesnt seem to work for me

[vernal grail]

ah weird

[hoary kindle]

Ive never tried to fix it though so its potentially just a set up issue

[vernal grail]

could be a pdf viewer issue

never used vscode but I would guess it probably doesn't use zathura

(that plugin I mean)

but vimtex + zathura works

[vernal grail]

it might also be ctrl-click instead of just click or double click

[hoary kindle]

Holy shit

[vernal grail]

:p

[hoary kindle]

Its a ctrl-click lol

Ive never been super bothered by it because it has a stucture tab, so I can jump to subheadings and stuff, but thats very nice, thank you for helping me realise that. Ive only used VSCode all day every day for the last 4 years

[iron nexus]

i cant do 678436487 x 618313278101019827381 becouse its 678436487 to the power of 5771828317673877728929.678263178287751

[elfin oasis]

opening this channel to the public was a really good idea

[queen trail]

wait

wtf is this

[unreal mulch]

Go ask this somewhere else

[severe shard]

right sorry

[snow steeple]

good channel idea

so now i can hide it

[eager halo]

Did you do only a click? Ctrl + Left Mouse Click on the native PDF viewer allows you to jump to the corresponding latex code.

Oh my bad. Someone mentioned it below your original message already.

[scenic shuttle]

I'm looking to get started with studying physics as self-study over the summer break. does anyone have any study methods?

also should I stick with latex or try something else? maybe cause I want diagrams for sure

I'd appreciate any advice

[main trail]

TiZ for diagrams

[hoary kindle]

I mean you can use TiKz but you’ll probably spend a similar amount of time making graphics to actually studying

If all you’re making is study notes, take the cheap and dirty route and just include your hand drawn ones as images

[unreal mulch]

For me, I used Obsidian for note-taking, with a pdf reader that allows highlighting text. All exercises are done in Obsidian, and the diagrams were drawn in TikZ and rendered in Obsidian.

[rocky terrace]

Richard Borcherds! so based

I gotta start watching his algebra lectures

[rocky terrace]

My study methods for studying physics are

learn the contents of the chapter
try to solve as many exercises as possible
repeat

also I don't know if you want to Tikz up diagrams, it will take a long time because espcially in classical mechanics you will be drawing a lot of diagrams when solving problems

But it's so satisfying when you draw a diagram of the problem set up and everything falls in to place

I had this experience with the loop problem in chapter 7 of Taylor

[raw tinsel]

wheres the experiments ...

[rocky terrace]

In our minds

Theorist supremacy

[raw tinsel]

so everyones just a philosopher

[fleet hill]

If you want to go into math/physics in the future, it's prob good to use this as an opportunity to get fluent with latex, I agree with Nope for just hand-drawing diagrams for now

You can insert them into a LaTeX document using \includegraphics

[rocky terrace]

Also LaTeXing up stuff is really fun

[eager halo]

I mean you can use TiKz but you’ll probably spend a similar amount of time making graphics to actually studying
I am the evidence.

[eager halo]

Yeah or use inkscape, which is the method Matplotlib stands by.

You can get some very professional looking diagrams with inkscape. But I still stick to TiKz for the maximally massochistic experience

[hoary kindle]

Inkscape is also nice if you have some diagrams already in a book and you want to manipulate them, it can extract the vector graphics from a PDF

I’ve been doing that for ZX diagram stuff this semester, because dear Christ those are painful

Even with tikzit it hurts

[eager halo]

ZX diagram?

[hoary kindle]

Cause like uhh, I’m not making that myself

[hoary kindle]

Quantum programming stuff, it’s a graphical calculus based on the theory of monoidal categories

[eager halo]

I see

Some diagrams I have made in recent weeks

Still trying to correct the arrowhead positioning in the last one, but I have no fucking idea how the code for the arrowheads works

Arrowheads in question:

[hoary kindle]

But yeah long story short, avoid every using Tikz if you can help it

It’s unbelievably time consuming and unless you’re like writing a paper or a book people will actually read it’s just not worth the effort

[eager halo]

Well, Tikz can be incredibly satisfying, at least to me.

So, I think it can be nice if you have the time to spare.

A nice side hobby, if you will.

[hoary kindle]

Yeah it makes beautiful things and if you have fun doing it, go crazy, but if your goal is to study physics it’s probably detrimental

[eager halo]

Yeah

I have so much math I want to learn but I'm using a lot of time for tikz

Learn tikz to illustrate mathematical ideas ❌
Learn math to have more tikz diagrams to draw ✅

[rocky terrace]

grass: I wanna do more math everyday
also grass: is trying to convince himself that he's not just slacking off by spending time on Tikz all day long

[eager halo]

[rocky terrace]

hestrue

[eager halo]

Its so satisfying to draw nice tikz diagrams

You can't blame me

[rocky terrace]

[eager halo]

https://tenor.com/view/darkness-kono-suba-anime-blush-heavily-breathing-gif-13932463

Maybe I should try learning Asymptote, too.

[elfin oasis]

tikz isnt that bad

iguess

its better than using anything else to draw it on the computer

[raven kindle]

inkscape

[elfin oasis]

and smtimes when u import screenshots into latex u just think maybe ill not do latex notes at all

[elfin oasis]

i use it when i need to draw like. curves

but using two apps :( cant do that :(

[raven kindle]

lmao

[elfin oasis]

im happy with my decently buggy latex snippet thing

[eager halo]

Eh. It can be a pretty big pain in the arse

especially if you're trying to do something you're not used to

[unreal mulch]

What’s your opinion on using LLMs to generate tikz diagrams?

[rocky terrace]

does that actually work?

[strange tiger]

anybody know some good youtube videos to learn basic counting and graphs?

[rocky terrace]

Does it actually generate what you want it to generate?

[tight siren]

#latex-help

or switch to typst

[unreal mulch]

It’s better than starting from scratch atleast

I don’t have other usages for my o4-mini quotas so

[brisk heath]

It's not very good but as you say it's a great starting point

[raven kindle]

it sort of works if you yell at it a lot and you manually adjust some of the numbers

as for whether it is easier than doing it completely by hand, ig it depends

[eager halo]

https://tenor.com/view/anime-glasses-push-nerd-gif-4899021

I have already gotten help on tex stack exchange

I wasn't asking for help here, just showing the pains of tikz.

[eager halo]

How would that help in the slightest

[eager halo]

Well, I asked that in relation to diagram drawing.

Does typst have nice vector graphics package(s)?

[elfin oasis]

doing smth new is hard
wow. thats poignant

[eager halo]

If you do the same thing on paper, its faster and easier by leagues and miles.

[drifting crystal]

typst is great but for a figure like this you’re gonna be in the shit no matter what

Although, one benefit typst has is if something follows a regular pattern, you can automate it using some of its scripting capabilities. Like using a for loop or something. So in some cases you can greatly reduce the necessary code.

[eager halo]

Tikz also has foreach loops

[drifting crystal]

good to know

tbh I’ve never used tikz for plots.

I’ve just used tikz-cd for commutative diagrams, and the circuitikz and quantum circuit (whatever it’s called) packages

for plots I’m throwing it into matplotlib

[rocky terrace]

@ matplotlib

[latent ferry]

how do u close a chat from a post?

[median geode]

Just type .close

In the form you want to close

[hoary kindle]

Just as an FYI if you’re not aware of it, tikzit is a nice GUI way to do ZX calc for quantum stuff

[drifting crystal]

Thanks for the suggestion.

[hoary kindle]

And for more circuity stuff, would qiskit not be slightly less painful? Perhaps I just really hate tikz but I will avoid it if I can lol

[drifting crystal]

I had been using quiver for commutative diagrams and doing the quantum circuits by hand

qiskit is good. I should probably use it more often

It makes sense to use now that you mention it. I had been using matplotlib for plots afterall.

But tikzit does look great for general string diagrams

[hoary kindle]

Yeah I found it easier to use for ZX stuff than string diagrams generally, but I haven’t spent enough time learning to use it to be honest.

There’s also freetikz, but I’m so shit at drawing I struggled with it lol

Still it’s a good way to get roughly what you’re after then you can just edit the tikz it spits out

[scenic shuttle]

I knew everyone is gonna say tikz

[scenic shuttle]

not going into math or physics in the future it's just engineering things in general cause you need physics. also I've used tikz before with math and it's just so painful, takes a lot of time indeed. so I'll keep in mind to draw the diagrams on ipad and make it regular if it's taking too much time for sure

the \includegraphics is what I usually do

like this is fine i guess

[raven kindle]

inkscape 🗿

[fleet hill]

lol yeah I feel like there's no point in learning tikz for this, although you might be able to get chatgpt to generate you tikz code tbh

[hoary kindle]

FreeTiKz could be good if you have a drawing tablet

Possibly better than chatgpt, but i don’t have enough experience with either to really say. It’s rare that I need to do anything more than a commutative diagram, and when I do I usually just adapt stuff I can already find

[raven kindle]

yeah and there is https://q.uiver.app/ for commie diagrams

[scenic shuttle]

gpt sucks #advanced-lounge message

[scenic shuttle]

i tried this but how i can make the object comes a little bit closer

since it won’t let me

[fleet hill]

hahaha

[raven kindle]

wdym comes a little bit closer

[safe harbor]

Learning TikZ isn't that bad. Using it can be a pain though, but I don't think that's specific to TikZ. Creating graphics in general is hard and time-consuming

[fleet hill]

I don't think learning it is that bad but it's probably pointless if you're not going into math, physics, etc.

I'm guessing if you're going into science or engineering, your time is better spent learning Illustrator/Inkscape

[scenic shuttle]

honestly i can’t find it so im gonna move on

dw about it

[safe harbor]

Probably

But the best is to learn PDF graphics operators so you can implement TikZ stuff yourself

[plain geode]

is making organized calculations important? like when ur doing a math test and the teacher gives you one of those blank sheets, this is how i usually calculate on most questions, id love to hear thoughts

[storm tide]

Depends on whether you're handing that sheet in as an answer or it's just for scratch work?

[plain geode]

just for scratch work

i see a lot of people online doing super fancy scratch work, so i got curious to see if its truly necessary

[green terrace]

If it helps you organize your thoughts, maybe

Else not really, especially if it's scratch work

[rocky terrace]

though even for scratch work, you should make it at least a little bit organized, because I've sometimes done scratch work and come back to it to see that I don't understand anything I wrote

[queen stag]

At the very least, use symbols or arrows to connect one part of your writing to another

[fleet hill]

please keep it organized, it'll make your life easier

plus when you go to explain something to others you can just use your scratch work to show them which is nice

I think having an organized writing process can also help organizine your thinking about a problem, otherwise you're not really sure what you have or haven't figured out yet

unrelated: I made this monstrosity today while reviewing for a final...

[coral sleet]

you didn't write small enough

all of that should've been able to fit on one page

[coral sleet]

for scratch work, my notes are even messier

for anything I need to hand in, I do all the messy scratch work on a separate piece of paper, and neatly write up the solutions later

[rocky terrace]

[sinful zenith]

you're doing well, buddy. i do the same. Plus nobody gives you credit for calculations, do what floats your boat...

[robust briar]

Hey guys, I'm doing cartesian product right now, I'm taking discrete maths.

I might be a little sleepy but...

called a relation
• A={a, b, c} and B={0, 1, 2, 3}, R={(a, 0), (a, 1),
(a,3), (b, 1), (b, 2), (c, 0), (c,3)} is a relation
from A to B
• A x B ≠ B x A
– B x A = {(a, 1), (a, 2), (b, 1), (b, 2), (c, 1), (c, 2)}

Here in the last line, B x A, shouldn't the order of the elements be reversed? B = {0,1,2,3}, so we should start with that no?

And also, why were 0 and 3 not paired? Is there a mistake in the presentation I took this from or?

sorry should this be moved to a help forum?

very sorry guys wronf channel 🙏

[sinful zenith]

BxA is not that. it is {(0,a)...} and all the elements should be included. Rest however depends on the question configuration.

[robust briar]

The slide was misleading

[robust briar]

The final line uses the first line's set instead of the second one for whatever reason???

Extremely dumb and took me a while to realize it lol

[olive geode]

Yes, this channel is for discussion about study techniques and such

[robust briar]

my apologies, first time using this server, i moved it to another channel afterwards. I answered my own question

[olive geode]

Anyone using Anki here? I started using it very diligently last semester, but I haven't used it at all this spring. I think maybe because there's less weird stuff to remember in the courses I'm taking now, and I'm trying to focus more on doing exercises instead

[fleet hill]

I really like it! Haven't used it for math before tho

I know someone here uses it for math...

@kindred vine and @short dirge ?

oh waittt maybe it was swiftee not suremark oops

[short dirge]

definitely not me, i don't know what anki is haha

[fleet hill]

it's a flashcard program lol

[short dirge]

ah

[olive geode]

I remember there was someone who loved Anki here, I think they were called Pseudo something? Haven't seen them in ages tho

[olive geode]

I'm guessing you use it to learn languages?

[grave pawn]

I need mathematical advice, I'm planning to take the EA exam of the summer July 18th approximately, to take the Algebra 2, I'm currently using Khan Academy, and wondering if it's a smart decision.
I already took algebra one and geometry, and I'm debating if I should schedule the exam, if I don't pass it's on my transcript. https://www.friscoisd.org/departments/testing/home/exam-acceleration
Exam for Acceleration (EA) - Provides an opportunity to earn grade level or course credit in which no prior formal instruction was completed. The EA is designed for a very small percentage of learners who have both the academic and emotional need to advance a course. Exam for Acceleration is not designed for grade level recovery when a student is retained in a previous grade level. Students must demonstrate mastery of 80% or higher on an EA to earn credit.
Thanks to anyone who give me advice.

[grave pawn]

Could you help please.

[fleet hill]

yeah and neuroscience terms

[fleet hill]

@tropic void heyhey

do you have access through a university slash library? otherwise there are a number of math textbooks that are freely available online on the author's webpage

[fleet hill]

what does the exam get you if you pass?

ohh

[olive geode]

Ah yes, that was the name!

[fleet hill]

I would say typically I read them very slowly, I try to take a little time to attempt to prove theorems myself when I can without looking at the book, I try to make sure to do the exercises, etc

that's in an ideal world, in reality sometimes I just skim books and hope for the best...

it's always nice to read and talk about books with friends tho

[olive geode]

For taking notes, I think a good approach could be to reproduce what's in the book, but without looking at the book. Try to write down theorems, proofs and definitions from memory, then just sneak peek at the book if you need to

And it's good to bear in mind that reading a textbook is usually very nonlinear, you need to jump back and forth a lot. Don't be afraid to skip sections you are struggling a lot with, you can just come back to them later

[fleet hill]

I personally don't really take notes on math texts unless I'm really struggling to recall definitions

Maybe I'll take notes at the end of the chapter briefly on the main points of the chapter as review

the most important part is prob just to go slow enough that you don't trick yourself to thinking that you understand stuff when you don't, but fast enough that you feel like you're making reasonable progress

if you feel like that's impossible, it might be good to just find another book

[grave pawn]

I get to go to AP Pre-Calc, and a credit for math, but it doesn't count to GPA.

@fleet hill

[grave pawn]

Please let me know when you come back, thanks!

[steep grove]

wtf is this

[somber merlin]

can i dm someone my math questions

[gaunt ruin]

you can just open a help channel with your doubts

[grave pawn]

It's not allowed

[gaunt ruin]

wdym?

[grave pawn]

I can't

According to a moderator in the server.

[olive geode]

who said that? Why would you not be allowed to open a help channel?

[gaunt ruin]

bro you tripping hard

[scenic shuttle]

lmao

[gaunt ruin]

lmfao

[rocky terrace]

they should learn from me fr fr

[grave pawn]

A moderator

He said that this is the best place, and that help is only for math problems.

[fleet hill]

they weren't talking to you

they were talking to the person looking for help with math problems

[fleet hill]

oh okay, yeah that seems like a good thing to try for!

[main trail]

how to study during exam season

I just can't study during exam season

[fleet hill]

what do you think is the issue? like anxiety or not having enough time or something else

[main trail]

No, just lose interest

[fleet hill]

why do you think that is

[neat meadow]

Study before the exam season . Can I have more context

[reef ocean]

for the long term yeah "study before" is good advice, it's best to review your notes or do some exercises roughly every week during the semester, and on another hand it's normal to feel more anxious or lacking time during exam season

or worn out as well

[main trail]

That's what I do

so I just lose interest during exam season

Start anticipating the new content

[neat meadow]

Maybe don’t study before exam season and study when exam season starts? A rly bad idea but eh

[main trail]

Very bad idea impo

[neat meadow]

Well I suggested it particularly because you got bored

During the exam season because of you studying before hand

[main trail]

It's more like next sem is very exciting for me

RA, AA, Dif Geo, Operator theory, probability

And this sem is just calc

so you can understand why I'm bored

[neat meadow]

Multi calc right

[neat meadow]

Still study so you don’t bomb exam

[main trail]

yea

[main trail]

I've studied

[neat meadow]

When is exam

[main trail]

2pm

,ti

[mossy shadow]

The current time for math_rocks is 08:20 AM (IST) on Tue, 29/04/2025.

[neat meadow]

I think it’s a bit to late to study then

Last minute review might be needed

[main trail]

I know, but as I've said, I studied,( even yesterday), just with as uch enthu as I would have liked

[neat meadow]

What is uch enthu

[main trail]

much enthusiasm

[junior dagger]

holy this sounds so fun

[main trail]

It is

:D

Operator isn't confirmed( There's another course that may win over it)

[junior dagger]

👀

[main trail]

but diff geo is

[neat meadow]

What about point set top

[main trail]

I think that will be offered later

I think this is a course specially designed for 2nd years

[soft depot]

so is it correct for me to use this channel to avoid studying but instead thinking about how to study?

[rocky terrace]

diff geo of curves and surfaces probably

[rocky terrace]

No that's #「the-obsidian-twink-jesus」

[main trail]

yea

[rocky terrace]

Lol I confused you with Eric for a second

he was greenrole for a bit

[rocky terrace]

Have fun

it's so goated

[main trail]

imo

[main trail]

Next sem is 🔥 🔥 🔥

[lavish breach]

Anyone know where I can go to get a better understanding of the differential operator (d_/dx). I'm just a bit confused on how you can and can't algebraically manipulate them and the reasoning behind it.

Trying to get ahead in school and I've gotten to a bit of a block

[raven kindle]

Wdym algebraically manipulate ?

[main trail]

🔥 Operator Mentioned 🔥

[rocky terrace]

Like (D^2 + D + 1)f = 0

[lavish breach]

Multiply, devide, factor, cancel

Etc

[raven kindle]

Like multiplying through by "dx" ? Or do you mean treating D as linear operator

[lavish breach]

I'm in calc 1 can u dum it down a bit

[raven kindle]

Wdym

[lavish breach]

The properties covered in algebra 1 basically

[raven kindle]

On what

[lavish breach]

With variables

[subtle crown]

"factoring out" the derivative is dependent on what d/dx "distributes" over in the first place

i use quotations because we kinda treat the derivative in handwavy ways

[rocky terrace]

so you know functions right? a function is a map f : D --> C, from a domain D to a codomain C, we have something called operators which are basically the same as functions, but the domain now is itself a space of functions

[subtle crown]

probably still a little too complicated of a way to describe it

[rocky terrace]

the "multiplication" of operators D you've seen is literally just function composition

and taking inverses (that would be dividing I guess)

[raven kindle]

D (derivative) is a linear operator which means D(cf(x)) = cD(f(x)) and D(f(x) + g(x)) = D(f(x)) + D(g(x)) and prob smth I'm forgetting

[subtle crown]

nah thats it

[raven kindle]

okay

[main trail]

Probably taake thiis to a help channel ?no?

[subtle crown]

anyways, the only special ways that the derivative interacts with a function is the fact its linear

otherwise its pretty normal

[main trail]

or #math-discussion

[subtle crown]

function-wise

[lavish breach]

Alright

[rocky terrace]

normal operators mentioned??!?!?

[subtle crown]

every day i wait to eventually study hilbert spaces

idek if i will end up doing so

ig ill see

[main trail]

I just want to be done with this sem 😭

So boring

[rocky terrace]

you will func anal is SO fun

everyday I too wait to study it

[subtle crown]

func anal is the highest level of math here at my college

[rocky terrace]

isn't it exam season?

[subtle crown]

just like in terms of how the classes are numbered

[rocky terrace]

so you will get your wish soon enough

[main trail]

It is, exams end on the 3rd for me

[rocky terrace]

May?

[main trail]

yea

[subtle crown]

i want this semester to be over so im free from writing papers

[main trail]

But I stay until the 15th 😔

[rocky terrace]

my last exam is tomorrow, after that I gotta grind to get into a good maser's program

[rocky terrace]

[subtle crown]

man i think i might have to change my secondary major

[main trail]

Good luck! Applying to ISI and CMI I pressume?

[rocky terrace]

you're double majoring?

[rocky terrace]

yup and other institutes as well

[subtle crown]

writing papers is like the entirety of philosophy and i just cant make myself enjoy it

[main trail]

Awesome! Good luck!

[subtle crown]

yeah

[rocky terrace]

what are you writing papers on?

[subtle crown]

im procrastinating on one where im analyzing how Locke counters Descartes's account of rationalism

and how a rationalist might respond to locke

then theres another that ive been working on for months about AI ethics and mathematical logic

[main trail]

Did I share my insane progress with chat? Went from 0 in my first vector calc quiz, to 100 in last 2 ( and almost 100 in the midsem)

[subtle crown]

ive had huge writers block on that paper for weeks

[rocky terrace]

math + philosophy double major?

[subtle crown]

im still like 300 words short and its due in a week exactly

[subtle crown]

yeah though philosophy will prob be a minor

[rocky terrace]

awesome!

[subtle crown]

or ill switch it

[rocky terrace]

switch to physics

[subtle crown]

since i want to focus on math

[rocky terrace]

come to physics

[subtle crown]

no id have to take gen chem 1

nothing is worth taking gen chem 1 again

[rocky terrace]

can't you take an equivalent class to gen chem 1?

[subtle crown]

i just dont want to do anything of the sort

plus i probably wouldnt like physics very much anyways

ive heard it just lacks a lot of rigor that math has for too long

[rocky terrace]

you would love it

it lacks mathematical rigor yes, but that's because physics' job is to describe the universe, so proof are replaces by experiments

[subtle crown]

well yeah but i dont care about experiments

[rocky terrace]

experiments are proof that your theory is a correct model of the universe 🔥

[subtle crown]

erm technically they are just evidence

[rocky terrace]

theoretical physics

[subtle crown]

i might do theoretical physics eventually

i think my fall research plans are related to it

but id need to do too much other stuff that i just dont have the will to do

if i switched majors from philosophy id probably switch to percussion performance because ive always loved drumming and playing all the keyboard instruments

plus i dont really have to worry about job security because im pretty sure the industry for math majors is doing just fine

[main trail]

I'm planning to minor in Sociology bad idea?

[subtle crown]

so i can chill with my secondary area of study

(btw should we take this to advanced lounge)

[main trail]

I did one course, I really enjoyed it

[subtle crown]

i love how canvas messages you multiple times about grades

i get to see the 78% i got on my hume quiz multiple times

[glacial raven]

Any number theorist here

[scenic shuttle]

@crimson elm

[rocky terrace]

deltoid does number theory?

[glacial raven]

And anyone who knows a lot about 3d geometry

[vernal sky]

bestie...

[worn jasper]

is studying for IMO worth it?
or should I switch to immc and programming

[rocky terrace]

Do whichever one you enjoy more

Learn number theory, Work for the government cracking codes

I think most governments do this no?

I see

[scenic shuttle]

yes

he loves logloglog

[scenic shuttle]

what's your question anyway

[fleet hill]

update: woooo crushed the final!!!

[glacial raven]

are there any discord servers about numberical optimization

what

I don't know what channel I am typing this in but whatever

[vernal sky]

theres a channel #optimization here dont know if youve seen that

ure in #study-discussion

[crimson elm]

Yes

[rocky terrace]

Let's gooo

[fleet hill]

if you're looking for a channel here, there's also #numerical-analysis in addition to #optimization

[lunar shard]

I always wondered, when studying what does everyone use / do with scrap paper? Doing math problems takes a lot of pages.

[main trail]

How do I get used to reading theorms peroperly

at times I think it's iff when it's only in ione direction

Like I did today, which is going to cost me heavily(1-2 marks 0n 60)

[rocky terrace]

I have a notebook

so I just do math in that notebook

there is no scrap paper

[main trail]

hmm, fair

[rocky terrace]

huh?

[main trail]

but when I read theorms at times but brain inserts an iff even if there' s only an if

[main trail]

nvm, wrong reply

[rocky terrace]

Most theorems are pretty clearly stated no?

[main trail]

yea

[rocky terrace]

with what theorem did this happen?

[main trail]

altenating convergence test

I said an alternating seqeunce doesn't converge as it isn't montonically decreasing

[rocky terrace]

[main trail]

which is onviously wrong

[rocky terrace]

you should recall the definition of a series converging, and compare it with that

[main trail]

like -1,1-1,1,1,1,1,... is a simple example

[main trail]

yeah, I know

the divergence test works easily here

the thing is , I thought it was an iff statement

I guess proving it earlier , wouuld have re-enforced that

[rocky terrace]

I'm not sure how that confusion happens

but one thing that can help is

to be on the look out for iff statements, since iff statements are relatively rare

most statements in math are if-then

and the converse is usually either false or only partial converses are available

[main trail]

yeah, I know

I should have studied more this sem

but I digress

[raw tinsel]

iffs are rare

you should be assuming the opposite and be surprised when a result is an iff

[main trail]

I think the fact that I didn't bother to prove these played a role

I don't think well under pressure

[raw tinsel]

they are especially rare in analysis

[rocky terrace]

calc 2 class?

[main trail]

yea

[rocky terrace]

yea then dw too much

[main trail]

should though, I've done proof writing ,a did well in taht too

😭

A- in that

This is def a bad sign

very bad sign

[winter nebula]

same

[fleet hill]

for what?

[fleet hill]

I keep a ton of loose scrap paper in my room from various old paper handouts and stuff, then I just write on it whenever I want to write out a problem

can't say it's the best approach but it is an approach... advantage is I never waste paper

[raw tinsel]

fire hazard

[fleet hill]

okay the pile of scrap paper is not that big

[dire eagle]

i just buy stacks of printer papers, much cheaper than notebooks

[raw tinsel]

buy?

i thought people stole those

For the record, I'm not in education any more.

[opal cargo]

I've got a few notebooks leftover from school cuz I didn't take notes anyway

and maybe a few nice markers that were... unattended to

parhaps abandoned

[crimson elm]

Any number theorists?
Yes
Doesn't answer back

[latent burrow]

medium size notbook

[opal granite]

I buy cheap notebooks in bulk

[raven kindle]

i use small notebooks for scrap work or chicken scratch note taking

then LaTeX it up

[opal granite]

Wish I had the energy to latex my notes

I tried to just take notes in latex in my first semester

Gave up after a week

[hasty geyser]

I find it fun and helps me find whatever I need

overleaf + table of contents

[viral osprey]

My alg prof very obviously writes all his class notes on the back of unused exam cover sheets.

[hazy vigil]

[viral osprey]

I haven't looked super closely so they might also be old exams

[raven kindle]

Completely unusable

I don't wanna learn helix 😔

hmm

what is the tikz equivalent

nah I tried it and it just wasn't for me

vern noun way more intuitive for me

b

is it as bad as tikz

bruh

im sticking to latex

😎

Skill issue

I type blindly and it always ends up being correct 🗿

I wrote 12 pages of LaTeX for my homework a week ago 😭

Real analysis is hard man

It was 4 problems

My solutions ended up being 12 pages total

Probably can be shorter than 12 pages I think a lot of my classmates did under 10

I mean it would be silly to not use latex

Handwriting that stuff is suicide

I scored among the highest though 🗿

Turn in latex

to show them who's boss

if their standards are low, raise them

What in the name of applied math is that

God I'm glad I never have to take applied math courses

Such a drag

oh

Praying for your wellbeing brother 🙏

ee is almost as hard as pure math I hear

maybe harder

So sweaty

Maybe that's just my uni?

[cyan adder]

EECS is very sweaty

[raven kindle]

ee major be like: they gave me a bunch of nand gate transistors and told me to make a cpu

😭

what is engineering math though

is calc 1-3 not engineering math??

Is it diffeqs

[raven kindle]

They call that calc 4 in my uni

Bruh

Very funny

unfortunate

I was wanting you to suffer with me

I suffer; everybody must then suffer!!

I don't know if I will get the opportunity to learn complex analysis from actual course. There's the complex variables course but the actual analysis is grad level at my uni 😔

and idk if I'm built different enough to be able to do that

[viral osprey]

How old are you?

Well you don't have to answer lmao

Pretty sure most folks in my phd program are around 24 or older

I am 33 so uhh...

Either you'll be fine (as far as age goes) if you wanna do more or I'm fucked!

[scenic shuttle]

just do ee

you dont have to do cs

[torn olive]

1: what is the point of that double major and 6 years of loans vs majoring in 1 and adding courses from the other as you please, especially if you want to do grad school afterwards.
2: many people enter grad school at a later age for a variety of reasons so don't fret about this.

or other way around idk

I mean did single major Math and CS minor and got to cherry pick the CS courses I wanted to do and this worked out well for me

money is a very valid concern

idk, I'm of the opinion that a double major is overrated

and that doing a single major and cherry picking courses from the other major for your free slots is the superior move

especially if it tacks on extra years that you have to pay for

but that's just my opinion not based on much more than vibes and my personal experience

[scenic shuttle]

that's true but I quit cs

everyone is literally replaced by ai

and they force you to learn a language that almost everyone hates it fr

[scenic shuttle]

no I meant javascript

and java too

both gave me mental illness

[raw tinsel]

javascript saved me from my illness

idk what ur on about

[scenic shuttle]

garbage language

[raw tinsel]

what isnt

[raw tinsel]

js has a very practical builtin ide to almost everyones systems

sorry but not sorry, get me one of those and ill switch to your lang 😔

your browsers dev console

[pure kettle]

Hello

[raven kindle]

All programming languages suck

Just use whatever works

[scenic shuttle]

I quit cs but im still gonna use py and julia

they're the best for me

[unreal mulch]

Python

[main trail]

I was forced to learn C

😔

[unreal mulch]

My condolences

Well, in a way that's a blessing.

You'll appreciate Rust more.

[raven kindle]

C is the least bad language

(still awful)

[raven kindle]

Or C

It's fairly minimalistic cmon

[main trail]

I have an exam on the same on the 3rd

finals

[rocky terrace]

There are only two kinds of programming languages

1. languages that people complain about
2. languages that no one uses

[viral osprey]

I have zero debt

My situation was complicated as I went to school mostly on the GI bill though.

I don't think I'd recommend this kind of plan to most folks.

[orchid shore]

gastrointestinal?

[main trail]

wait, what

wasn't that in the 1940s

[scenic shuttle]

1. I complain about java and js
2. I don't use assembly

[unreal mulch]

I mean if you mpreg you kinda use asm in an indirect way

Why is studiscussy devolving to CS

[scenic shuttle]

I don't get it

[unreal mulch]

ffmpeg**

It’s written in assembly, by hands

[scenic shuttle]

I see

[scenic shuttle]

everywhere is a #cs-chat

[unreal mulch]

Speaking of that, I need to make an ffmpeg wrapper, I’ll probably ship it as a SaaS too

[scenic shuttle]

have fun!

[glacial raven]

Shhhhhh let it cook

[viral osprey]

Yes I am pushing 100 at this point

Jk

The actual program began in the 1940s but still currently exists.

[raven kindle]

im gonna puke
"studiscussy"

[unreal mulch]

It’s study+discussy

[quasi smelt]

So real.

It's the simplest language that teaches you about what's happening under the hood. When you see C code you know what it's doing with the computer.

I'm learning Rust currently.

I'm just done with so much of memory problems just in getting a string.

[cobalt sun]

can we move to a diff channel

[quasi smelt]

which one and why?

[cobalt sun]

it's off topic

[quasi smelt]

Ohh maybe because this is for study

[quasi smelt]

ohh yeah sorry

[cobalt sun]

uh huh

i gathered that much

[drifting crystal]

Because cs is really cool

Also all the cs people have taken over I guess

[heavy carbon]

Hi!

Im iraqi btw

[orchid shore]

hi iraqi btw I'm ksor

[main trail]

I hate pointers in C

my god

[rocky terrace]

They are very useful

[upper imp]

can someone help me with percentage increases & decreases

[torn olive]

#❓how-to-get-help

[raven kindle]

What why 😭

You can make so many cool custom data structures

[green terrace]

Pointer syntax is intuitive

Use * on the left side to indicate a pointer type, * on the right to dereference a pointer, and & to make a pointer by grabbing an address

[raw tinsel]

*a = addrOf(a)
&a = valueAt(a)

[cobalt sun]

yeah

[raw tinsel]

its just compact

[gaunt ruin]

what about ** or &&

[short dirge]

isn’t this backwards

also study discussion = cs discussion once again

[gaunt ruin]

yes.

[cobalt sun]

time to promote #1213610885277421588 to a full channel

[gaunt ruin]

&a gives the address, thats for sure

and *a should give the value stored at a, if I am not mistaken

[short dirge]

yea

[gaunt ruin]

contradictory how people say something is intuitive, yet they confuse them while attempting to give an example

a classic of how easy is to shoot yourself in the foot with c++, by the time you think you know something, you dont

[uncut saffron]

I just started partial derivatives, working through James Stewart Essential Calculus

Which style of d should I use for the partial derivative? I like the first and last but I'm not sure if the small delta is appropriate ? I'm really picky about the style haha

I've seen quite a few ways people write it lol

[raven kindle]

Not the left one, that's lowercase delta

Mine is similar to the one on the far right

[uncut saffron]

I suppose the 2nd is easiest to write but could also be easy to write too wide, kind of like drawing a semicircle then closing half of it with a circle, last one I guess is really like a super curvy lowercase d isn't it. I'm just thinking about a shape to think while writing to allow myself to make the calligraphy consistent so I can write it very neatly without lots of variations in shape

[rocky terrace]

any of 2, 3, 5, 6

1 and 4 are weird and shouldn't be used to denote partial derivatives

alternatively you could use the much easier Lagrange's notation

$\frac{\partial}{\partial y} \frac{\partial f}{\partial x} = f_{xy}$

[mossy shadow]

Neamesis

[uncut saffron]

Ah yes ofc, Lagrange notation looks quite easy to write consistently. Thank you all :)
I've gotten it down to more of 2 but narrower, so far trying to write the little bend like on 6 makes me a lot less consistent lol

[little smelt]

I default to subscripts for partials unless I have a bunch of indices

on paper at least

I mean if you only have like a few expressions w partials that’s one thing but like if they’re more frequent it’s a lot more efficient

to do subscripts

[little smelt]

that being said 2nd from left and far right are def the best

as qiu mentioned tho don’t do the lowercase delta

4th from left is just fried idk who sanctioned that

[rocky terrace]

your name

[little smelt]

LMAO

[uncut saffron]

As I started working on problems I started to realize how much nicer that is just writing like f_xy and such lol

[uncut saffron]

Hahaha yeah I realized after I sent it I'm like "wait lower delta does not seem right actually"

[little smelt]

real yeah

[brazen mist]

\[\del_x \del_y f\]

[mossy shadow]

Zanarcane

[little smelt]

ts pmo

[opal cargo]

hm, what package is that from?

[little smelt]

I dunno what package does that in particular but it’s just like defining \del as \partial

[raven kindle]

,, \partial

[mossy shadow]

qiu

[raven kindle]

Same thing?

[little smelt]

hmmmmmmmm

yeah I think it is and the color scheme accounts for any perceived difference

I mean u could always just overlay it to check but I’m on my phone so

[rocky terrace]

You know I think the biggest obstacle, at least one of the biggest obstacles when I'm self-learning math is struggling to find someone to check my proofs and my solutions to problems

If you're in a university and are taking a course on something, the professor will assign homework problems and you'll do the homework, submit it and the professor will check your work

that's basically part of the prof's job

But when you're self-learning something out of a book and you're doing the exercises, you need someone to check if your proof are correct

for that (and more!) this server is amazing

[rocky terrace]

Eric did say that I should get used to checking my own work

and get better at it, which makes sense. You can't just close your eyes and say "okay I'm done! Someone check my proof" after finishing a proof

you have to look at it and read through it and check if each step logically follows from the previous one

I need to work on that

[rocky terrace]

perhaps even multiple times! perhaps even upside down!

it is hard to catch mistakes in your own work

[safe harbor]

You can check the meanings lol

See if they're the same

Ah Xannie just defines \del to be \partial in his preamble

[main trail]

Is it just me, or does anyone else hate coding

[unreal mulch]

I hate coding too, I enjoy programming though

[main trail]

Okay, I hate coding and programming

[unreal mulch]

Oh. Fair.

[rocky terrace]

I love programming

especially graphics programming

🔥

[orchid shore]

it's neutral to me. i like to see it like knowing how to use a drill or something, useful skill at times, can be fun at times, but I probably have more fun hobbies that take priority, and I definitely wouldn't like to work as one nor am I good enough for that

[rocky terrace]

a power tools are cool as hell

C is a pain
