tbf i had coffee on an empty stomach so i think that might be part of it.

[solid yarrow]

math allergy

[velvet dagger]

Will you get an opportunity to eat soon?

This is a good system. Have the kid try a bunch of things, maybe see if there are modifications of foods that they like which are healthier and which they still like

Etc

[timid bronze]

Oh i just did

But

Still.

IM GONNA RUN!!

[velvet dagger]

Yeah that's fair it'll take a while to kick in

[timid bronze]

JUMP OFF A BUILDING

[velvet dagger]

[latent edge]

I get itchy from long hair

[timid bronze]

one of ym friends fold me

“Ur like me when im drunk”

Like breh.

[velvet dagger]

LMAO

[timid bronze]

Is coffee my way of getting tipsy them without gettimg tipsy

[solid yarrow]

yes

[jaunty ibex]

ur future gf is cooked

[timid bronze]

Depends if im not intolerant

dueing finals month i was so damn ineranf to coffee

[solid yarrow]

hm

[timid bronze]

interoleant

[velvet dagger]

For some people, alcohol makes them hyper

[latent edge]

not if my gf has small hair

[velvet dagger]

Among other things

[solid yarrow]

:3

how are you dami, when you're drunk?

[timid bronze]

He doesnt drink

[solid yarrow]

[timid bronze]

We dont

[solid yarrow]

oh

[velvet dagger]

Yeah I never drink

[solid yarrow]

ic

[latent edge]

I do

[solid yarrow]

:3

[timid bronze]

jd cut off a friend if they make me jokingly drink it

[solid yarrow]

deltoid and f0xy drinking together when?

[latent edge]

:3

[timid bronze]

even tho

jts easy to tell if a drinks alcohol lol

[latent edge]

OMG WHEN

I should go to germany for masters fr

[solid yarrow]

:3

fr fr

[jaunty ibex]

Deltoid when alcohol mentioned:

[latent edge]

i swear im not alcoholic chat

[solid yarrow]

._.

[timid bronze]

i neber got an actual haircut aside from dead hair trimming but my hair like goes to my upper back

[solid yarrow]

LMAO

[timid bronze]

if straightened

[velvet dagger]

Oh yeah I would NOT be happy

If I got tricked into drinking

[timid bronze]

i dont even drink beverages given from friends tbh

unless we like

[latent edge]

is it some religious thing?

[timid bronze]

buy it together or

given collectivelt

[latent edge]

dami

[timid bronze]

no cuz dami one tome in

school

some random girl came up to me drinking her iced green tea and was like

“U want it i dont want it anymore”

Like tf.

Idk u and ur asking me if u wanna share a drink

[thorn wren]

where I'm from that doesn't happen because alcohol is too expensive to give away to other people

[timid bronze]

I dont eben liek sharing drinks with friends

ew

[velvet dagger]

Yeah. But even if my reasons for drinking were not religious I'd be not happy if someone tried to trick me

[latent edge]

tricking someone into drinking is really rude

[timid bronze]

ill only share. drink with my future partner bc we r kissing and shit anyay lol

[velvet dagger]

LMAO that's crazy

[latent edge]

Like I only drink with my friends when we are on agreement it is okay and it's for fun

[velvet dagger]

The only way I've shared is if like, eg one of us gets a drink which we think the other should try because it's good. So you give to your friend first and they waterfall it

[latent edge]

forcefully doing it is incredibly rude

[timid bronze]

depends

[fresh comet]

I'd be extremely upset if I was tricked into drinking alcohol

[timid bronze]

both have to waterfall it

once their lips touch the drink

im not habingnit

[timid bronze]

im just cutting them off simple lol

Unfunmy shit

[fresh comet]

this is one of the few single actions a friend could do that would seriously make me angry with them

[velvet dagger]

I was thinking person A owns the drink. You just bought it and are like ah before I start, wanna try? Person B waterfalls, gives back to A, A drinks normally

[timid bronze]

Yeah

im fine w this

[latent edge]

@jaunty ibex number fields meeting when chat

[timid bronze]

as long as its before

their lips touch

[floral grotto]

yo yo yo

[timid bronze]

evem worse if its one of those kids who

drink with a straw and

some of their drinks comes out of straw back into drink

[jaunty ibex]

I'm not meeting anyone till I finish from waterloo + 3 months after

[timid bronze]

☠️

[latent edge]

bro what are they forcing u to do wtf

[velvet dagger]

Oh yeah def not

[timid bronze]

omg but i saw this like

persons ranking of

[jagged forge]

i had cottage cheese for the first time last year. i did not enjoy it much

[timid bronze]

most annoying pet peeves and

they put chewing w mouth open at 8

like what the sigma

thats one of my top 4

pls domt eat w ur mouth open in front of me

[jaunty ibex]

You know that eng student meme? That's me rn

[timid bronze]

Dont chew loud either

[jaunty ibex]

But math masters

[timid bronze]

i fucking hate cottage cheese

that shit makes me choke

[elfin smelt]

i literally heard their math department described as a prison

[jagged forge]

iirc it had kind of an unpleasant texture

[timid bronze]

ngl the chem department here sucks ass

[floral grotto]

what are your god damn goofy pronouns

[timid bronze]

a lot of the profs but

i still love rhe subject its ok.

[latent edge]

which uni?

[elfin smelt]

waterloo

[timid bronze]

one of the profs is soooo ableist though

[jaunty ibex]

It is true

[latent edge]

ah yeah

I am aware

[timid bronze]

the math department here i like but some ppl complain about it

[elfin smelt]

seeing someone after 3 months is gonna be like your alotted family meeting time 😭

[timid bronze]

not the worst tho def not as bad as chem

[velvet dagger]

I don't feel like I've often had the thought "Ugh why are you chewing with your mouth open" but idk if that means people mostly don't do it around me or if it means I don't notice

[timid bronze]

Bro

i just don’t t wanna see their

consumption of a food.

IT AO EW

[latent edge]

no fr tho take care of yourself

[timid bronze]

PLEASE CLOSE

MOT HAD

[jagged forge]

i had a friend who sometimes chewed with his mouth open

but he ate really slowly. like some kind of herbivore dinosaur

so i thought it was funny

[timid bronze]

LMFAOO

[bronze pelican]

This is why we should eat with masks on

[jaunty ibex]

Omg I'm mad again suremark WHY U BLOCK AAAAAAAA

[timid bronze]

ngl i eat so slow

im such a slow eater

my dad is always like

Hurry up.

[latent edge]

yes we need another covid era

[jagged forge]

eating slow is a good thing fr

[timid bronze]

not too slow

[jagged forge]

sometimes you finish your food in 5 minutes and you're like. damn i'm still hungry

[bronze pelican]

U don't need covid to wear masks

[velvet dagger]

Oh yeah that's valid I just mean, I don't know if people basically never do it around me or if I'm just not paying attention to notice

[jagged forge]

and then in 30 minutes you're like, why did i eat more

[timid bronze]

when i was super duper underweight and was getting treated they were timing our eating

and making us eat faster

😭

[velvet dagger]

Inverted for me

[latent edge]

breathing in your mask and making it humid inside...

[jagged forge]

oof

[velvet dagger]

I often finish food in ≤ 10 minutes

[timid bronze]

dining hall food takes me 50 years to finish

[jagged forge]

dami and i get each other fr fr

[timid bronze]

cuz of how bad it is

[latent edge]

i dont have u banned wtf

i mean blocked

oh wait u said suremark

im blind

[velvet dagger]

And parents are like yeah this isn't healthy take your time

[timid bronze]

my parents are religious and

since i need to partake in ramadan with them

[latent edge]

just have a tolerance towards BS vero like its not something you should be mad about

[timid bronze]

they usually tell us to speed eat for prayer since i need to go w them (im not religious) and

u get full fast

if u fast all day and eat quick

[latent edge]

if they block u its their choice and u cant do anything about it

just have some respect

[jagged forge]

i eat my breakfast slowly, but that's because i ate the same thing for 2 years and got tired of it

[latent edge]

anyway who wants to see my new terminal setup

[jagged forge]

(tofu and kimchi)

[latent edge]

based?

[velvet dagger]

This is true

[latent edge]

wait u got tired of tofu?

[velvet dagger]

Wait you deliberately eat only that?

[bronze pelican]

The miku setup

[latent edge]

yessir

[timid bronze]

ngl i skip breakfast a lot

[latent edge]

you get it yamin

[jagged forge]

yeah it's easy and has no carbs, and i do like it, just not as much as i used to

also it's not helped by the fact that it doesn't taste that good cold

[wicked mirage]

Hello

[jagged forge]

but by the time i finish it it always is

[velvet dagger]

Oof

[velvet dagger]

Same

[latent edge]

Hey do you have another RH proof?

[jagged forge]

i skip lunch these days

[velvet dagger]

Tbh I probably eat breakfast < 10% of the time

[jagged forge]

really my breakfast is more of a brunch in terms of timing anywaays

[wicked mirage]

I learned my lesson

[latent edge]

somehow i doubt that

but okay

[raven plaza]

I'm getting hungry but it's 2

[jagged forge]

yeah i mean, when you just serve it plain with kimchi, it gets boring after 2 years

[latent edge]

mood

[raven plaza]

Time is cruel

[latent edge]

i think thats true for any food

well

except for doner

I love doner

[jagged forge]

lol

[solid yarrow]

doner?

[latent edge]

yeah

[solid yarrow]

doner = döner?

[latent edge]

doner kebab

[solid yarrow]

ah

ic

[latent edge]

YES

[solid yarrow]

döner yummy

[latent edge]

omg foxy based

we should eat doner when we meet :3

[solid yarrow]

i was thinking the same

LMAO

And then go drinking straight afterwards :o

[latent edge]

sure

[solid yarrow]

so... when you will you visit again

[latent edge]

im seriously considering moving to germany

like

uhh maybe 2-3 years?

have u decided on what math u want to go into

[solid yarrow]

Not yet, why?

[latent edge]

nothing just curious

[craggy parcel]

to them the only counterexample is cranks which theyre not, so it makes sense in their heads

[solid yarrow]

Probably something analytical ig

Not sure why direction though

[latent edge]

what anal are u doing

im mostly doing harmonic/functional

[craggy parcel]

and some probability theory

[latent edge]

[craggy parcel]

nice

[latent edge]

scary

[solid yarrow]

o.O

I was thinking of reading a bit into that

[craggy parcel]

fairly elementary at the level im at but yeah it gets scary later on

[jagged forge]

i think i count 6 types of convergence ive encounted in probability theory now

[solid yarrow]

I feel that

[latent edge]

the two separate opencries

[craggy parcel]

im only a few pages into brezis but im liking it

[latent edge]

lmfao

[craggy parcel]

wheeze

its the same as "normal" in algebra

or "order"

[latent edge]

there's a reason why combinatorial number theory is scary

aside from combinatorics

There's a lot of probability

[limber thunder]

combinatorial NT alr has two scary things in its name

[latent edge]

one time I saw a damn ito integral and was terrified

yeah ig number theory itself is scary

but i have a stockholm syndrome so its ok now

[elfin smelt]

@latent edge get a cursor like this

Re @craggy parcel

[latent edge]

I got a quant intern cuz I yapped about probability theory

[short pivot]

i failed an online quant assessment recently. felt pretty bad about it

i also hate probability tho

[jagged forge]

we got:

• weak convergence
• weak-* convergence
• convergence in Lp norm
• a.e. convergence
• convergence in measure

then recently i learned there's something called "uniform convergence in probability"

is that enough types of convergence?!?!

[velvet dagger]

Oh I think there's more than that

[short pivot]

probably not

[latent edge]

online assessments sucked yeah

[latent edge]

There are more

[jagged forge]

enlighten me

i must know all types of convergence

[jagged forge]

well

usually the upper bound is like a sum of two or three epsilons each times a constant

and you're just like ahh well good enough

the reader can do the rest

[latent edge]

soture

[velvet dagger]

Ohhhhhhh wait I think I got confused because sometimes probabilists change the names of things

[jagged forge]

convergence in L1? whats that i only know about convergence in mean

or convergence in mean sQuArE

[latent edge]

There's probably some measure theory nonsense im messing that related to probability theory

oh i remember this

"Almost sure convergence"

I hate this term

[jagged forge]

ah yeah

a.e. (almost everywhere) is the measure theory term

[latent edge]

a.e is ok

a.s is bad

[jagged forge]

i dont really have a problem with a.s.

convergence in mean kinda sux tho

[solid yarrow]

A.s. is ass

[jagged forge]

or even a.s.s.

[solid yarrow]

Like it's a.e. eith a probability measure...

[elfin smelt]

degenerate divergence is a mean way to put it

[solid yarrow]

a.s. stupid

[jagged forge]

oh sometimes my textbook says "yes this converges a.s., in fact it converges surely"

[latent edge]

silly probability theorists

[velvet dagger]

Almost surely I'm fine with

But yeah convergence in distribution vs weak is what confused me

[solid yarrow]

Author on his way to converge to the hospital

[jagged forge]

ah

[velvet dagger]

Esp because they define it a priori differently, like oo CDFs converge at continuity points

But it turns out that's just equivalent LMAO

[jagged forge]

yea i hate this definition lmao

[velvet dagger]

Suremark you and I need to write a book that's mixed analysis and probability and situates the probability in the analysis more

[keen stirrup]

"surely" is always a funny term

[velvet dagger]

So eg we define weak convergence as in analysis and prove as a theorem that this is equivalent to convergence of CDFs at continuity points

Characteristic function as part of the general theory of the Fourier transform instead of some random trick you do to prove CLT

[jagged forge]

hmmm

[latent edge]

using characteristic function is so based

I am tired of random tricks

smh just do better

[jagged forge]

ngl im not actually sure what the relation is here. i have heard that convergence in distribution = weak-* convergence of the probability measures, dunno how that relates to the CDFs

i dont know enough FA fr

[velvet dagger]

X_n have CDFs F_n
X has CDF F

Convergence in distribution = F_n converge to F at all points where F is continuous

[jagged forge]

right yes

now what is weak (and weak-*) convergence here. what is the dual space of cdfs and what is the dual space of probability measures

[steel vessel]

Love u

[velvet dagger]

Yeah I think people say the measures converge weakly to mean weak* in functional analysis

[jagged forge]

o

[velvet dagger]

Yeah it's a pain

We need to standardize the terminology across subjects

And anyone who deviates from it gets all their papers retracted and credited to other people

And loses tenure

[limber thunder]

is this not a thing already

bogachev or something

[velvet dagger]

Maybe? Tbh the main probability book I know is Durrett

[jagged forge]

let's see what terms durrett uses

[limber thunder]

there's tons, I'm just getting into it 😵‍💫

probability/stochastics I mean

but I meant more in the sense of probability-aware measure theory book

[velvet dagger]

Ahh

[limber thunder]

with some non-trivial focus in types of convergence, Kolmogorov extension or whatever

[jagged forge]

funny quote from @odd brook about le gall's probability book

[velvet dagger]

We do an analysis book which is probability aware and puts a non-trivial amount of time to measures on finite sets, so it even discusses discrete probability extensively

And then gets into ergodic theory and GMT and functional and harmonic analysis

And the harmonic includes on groups

[thorn wren]

Tbf I found probability was a lot better at motivating measure theory than lebesgue integrals

[jagged forge]

hmm, well my analysis journey has basically been single mindedly pursuing probability

but at least from that perspective, i can say measure theory works pretty well for me as much as i bitch and moan about it sometimes

[thorn wren]

Honestly as someone who’s pretty strongly down the alg geo route atm, probability is definitely my second favourite branch

Am looking forward to stochastic analysis next semester

[raven plaza]

[rocky shuttle]

because it's cute

[velvet dagger]

What kinda stuff are you doing? Scheme theoretic, complex?

[thorn wren]

I saw the dead inside cat plushie and went that’s me

[thorn wren]

This sem I did a class titled “Stacks and Moduli Theory” that basically covered GIT and then a bunch of stuff about algebraic stacks

At the same time I’ve also been attending a seminar on etale cohomology that’s basically trying to give the details to someone who knows what a scheme is on the proofs of the Weil conjectures

I did scheme theory last semester out of Mumford

[velvet dagger]

Niiiiice

[thorn wren]

I still need to organise what I’m doing next sem beyond finishing szamuely and probably doing a seminar on motivic homotopy theory which should be sufficiently traumatic and convince me to do my honours thesis in analysis

[velvet dagger]

LMAO

[thorn wren]

What do you do?

[velvet dagger]

I want to be AG pilled one day. The main relevance to me rn is linear algebraic groups

[thorn wren]

Oh nice! I spent at least a few weeks thinking about those for GIT this sem

[velvet dagger]

I can masquerade as a combinatorist, dynamics/GGT guy, or number theorist

[thorn wren]

This sounds like being a mathematician

[velvet dagger]

HAH true

[thorn wren]

I do think if my math department had actual combinatorialists I would’ve had a solid chance of spending a lot more time in the area

[velvet dagger]

What I specifically do is study random walks on Bruhat-Tits buildings

Which are simplicial complexes constructed from p-adic groups

[thorn wren]

Unfortunately it seems the current staff are infected with the “combi isn’t real maths” ideology

[thorn wren]

Huh so is it like you take a simplicial complex with a p-adic action that’s somehow canonical

[velvet dagger]

Yeah. So the same way you can think of the hyperbolic plane as a homogeneous space for SL(2,R)

You get the p+1 regular tree as the building of PGL_2(Q_p)

[elfin smelt]

(do you have any good images?)

[thorn wren]

huh why the p+1 regular tree (I'm assuming this means a tree where every single vertice is attached to p+1 other vertices)

[thorn wren]

oh wait I forgot stuff is connected to something upstairs

[velvet dagger]

So, you take the space of "Z_p^2 lattices" in Q_p^2, up to homothety

Where L is homothetic to aL

For a in Q_p^x

This carries an action of PGL_2(Q_p)

Where okay if you take the Z_p span of a basis <a,b>, you hit them both with the matrix A and consider Z_p<Aa,Ab>

And since we're only considering lattices up to homothety

This is PGL

Anyway so the stabilizer of the usual copy of Z_p^2 is PGL_2(Z_p)

This is a maximal compact

So yeah our vertex set is just G/K

As in the Lie theory/hyperbolic geometry setting

Now what's the adjacency?

If you give me two homothety classes, we say they're adjacent if there exist representatives L and L' such that L is an index p subgroup of L'

Now you have to verify that this gives the (p+1)-regular tree

I won't go into the cycles but to see why it's p+1

Let's say L' = <a,b>

So that's where the p+1 comes from, the link of a vertex is a projective line over F_p

[thorn wren]

What does less than mean here? inclusion?

[velvet dagger]

Yeah, proper inclusion

And noting that these are subgroups

Instead of just subsets

[unborn meteor]

how

[thorn wren]

What motivates these?

[unborn meteor]

like utf-8 is castable to char* and uint16_t*

[velvet dagger]

So, on the one hand you have an analogy with geometry

You associate "symmetric spaces" to semisimple Lie groups

[elfin smelt]

this just means “is acted on by” right

[velvet dagger]

Hyperbolic plane is the symmetric space for SL(2,R), and there's a nice interaction between rep theory of G and analysis/geometry on H and its quotients

[dapper badge]

peak

[latent edge]

idk bro shit doesn't compile properly

[latent edge]

SL(2,R) mentioned

omg me when SL(2,R)/SO(2,R) = H

[thorn wren]

This is actually pretty cool. One of my friends was considering doing their undergrad thesis on this stuff at one point. I should try to pick it up one of these days

[latent edge]

If I recall correctly

There is no coxeter group for SL(2,Z)

but there is one for GL_2(Z)

the fundamental domain of H doesn't quite work well for reflections

[elfin smelt]

for various congruence subgroups there are iirc

like actually A_5 is mentioned as being iso to PSL_2(F_5) in that zagier talk

[latent edge]

ofc zagier would mentioned A_5 and PSL_2(F_5)

do u relate to any songs?

[flat harbor]

woke up 2hrs earlier than usual for a zoom meeting and dudes not reading my emails

[velvet dagger]

TRUUUUU

[flat harbor]

im gonna guess dude didnt consider that "wednesday 8am korea time" means tuesday in the states

[solar hawk]

[fresh comet]

I've seen a few people like that and they always scare me

especially the ones who aren't my peers, but are my TAs

[velvet dagger]

Damn that's impressive

[coarse bridge]

hai

[fresh comet]

they are! ~~but their existences also fuel my insecurity about being a poor speaker ~~

I want to be able to speak like that too

[timid bronze]

dude im a poor speaker too

u say i dont stutter but

i dont think uve vced w me enough to realize

and also im just shit at putting my thoughts into words

ur not alone

[fresh comet]

yeah I suffer from the same issue

my brain can know approximately how I feel about something, but then I can't find the words to say it

[coarse bridge]

Good song

[timid bronze]

Thx for being kind for once

[fresh comet]

it's a problem for me both in speech and in text, unfortunately

[timid bronze]

my brain will tell me exactly how to word it but then when i actually try to word it i forget how i wanted to do it

[coarse bridge]

the plan worked btw I woke up at like 6 something am and I’m sleeping at 10pm today

[fresh comet]

that's one step better than me

[fresh comet]

it's odd seeing you use this emote

[timid bronze]

dude say this and ruin it like 2 days later 🥀

[timid bronze]

ive used it sometimes

[coarse bridge]

I’ll try not to fr

[fresh comet]

apparently never in this server

[timid bronze]

yea get off discord vc step 1

[coarse bridge]

haven’t been on vc today to begin with vrovro

[timid bronze]

😂

[coarse bridge]

LMAO

[timid bronze]

U soooo funny

[coarse bridge]

thx

[fresh comet]

what does the wilted rose mean?

I keep seeing people post it

but I have no concept of what it's supposed to imply

[coarse bridge]

LMAO

[velvet dagger]

I need to talk more to philosophy types tbh it's such a vibe

[timid bronze]

idek what it means i just do it bc he does it im mocking him

[coarse bridge]

Idk if it can be put into words

it’s like

[timid bronze]

idk what the battery means either

[coarse bridge]

why we asking for definitions now gng 🥀

[timid bronze]

bruh uses gng too

[jagged forge]

it’s like an expression of disenthusiasm

if that were a word

[coarse bridge]

sorta yeah

[timid bronze]

Oh i see

[jagged forge]

for example

ally with those reacts 🥀

[timid bronze]

atp just go

[fresh comet]

I feel like I almost deserve at least one definition, given how many instances you've made me lose part of my brain

[coarse bridge]

LMAO

if i think of something suitable i'll let you know

[jagged forge]

u forgot to add the “vro 🪫” at the end

[timid bronze]

no im not saying vro type shit

[jagged forge]

r u sure

that was like 90% a chip sentence. u were really close

[coarse bridge]

she tries

[flat harbor]

id say vro shit for a brownie

[coarse bridge]

fr

[velvet dagger]

Atp js go does stand independently of Chip, of all the brain rot sentences

I think Chip's signature is using ts to mean "this" instead of "this shit"

[coarse bridge]

that's the common meaning vro 🥀

ts for "this shit" died in the victorian era

https://tenor.com/view/samsung-one-ui-samsung-one-ui-emoji-emoji-samsung-gif-15421094149726828842

[fresh comet]

wait, I thought ts meant "this"

[timid bronze]

my name is chipotle atp 🥀 i keep pulling allnighters tryna finish this dec topology but it’s not giving. like idk how i’ve been up 3 nights straight w nothing to show but 2 brain cells left and a half-done proof 😭 every time i open my notes i just sit there like 🧍🏽‍♀️ then scroll for 40 min telling myself i’ll start “in 5” ⏳ but 5 turns into 50 and now the sun is up. again. 🪦 this class got me in a chokehold fr. i don’t even know what we’re doing anymore. i just see ∃ and ∀ and start dissociating 😵‍💫 i’m running on vibes and caffeine and those are both low batt rn 🔋❌ like just go. pls. you pmo. i can’t keep living like this. 🥀

[fresh comet]

it's a curse word??

[coarse bridge]

[coarse bridge]

It does

[timid bronze]

no it means this shit

[coarse bridge]

No it doesn’t gng

[velvet dagger]

Common to your orbit

[coarse bridge]

aka all 250k here

LMAO what was that

[timid bronze]

Accident

[coarse bridge]

bro got automodded

[timid bronze]

i deleted it

[velvet dagger]

Your orbit is maybe 2 people

[timid bronze]

bro

[jagged forge]

yea im on the ts = “this shit” side

but my opinion doesn’t matter cuz i will never use it anyway

[timid bronze]

dami really broke his whole laptop cuz he lost at DRG to dandida & sharp 😭 like bro sat down in defeat and forgot the thing was on his chair… now it’s folded like a grilled cheese 💀 he was already malding from getting 3-0’d and then boom. instant silence. not from peace, but from the motherboard crying. now he’s pacing around the room talking abt “it’s fine i needed a new one anyway” w his hands on his head like this 💔 the L wasn’t just in-game. it was spiritual, emotional, financial. rest in pixels to that device 🥀🔋

[jagged forge]

damn

[velvet dagger]

🥀 🪫

[coarse bridge]

the two people: dami and suremark

[velvet dagger]

Blackbeard and flux lol

[coarse bridge]

we're nt counting space debris vro 🥀

[jagged forge]

oh it’s dutch

was boutta say thats some weird german

[fresh comet]

I still don't quite understand what this GIF means

[timid bronze]

i was assuming it was saying good morning but i sent the gif bc i t mskaes me shit every time

LMFAO

[fresh comet]

at least it shows my status, and part of my About Me

[timid bronze]

Not as bad as one video my friend made of me changing my pfp 80+ times within a few months

[velvet dagger]

Then no orbiters

[fresh comet]

I'm surprised they recorded so many pfp changes

[jagged forge]

devastating

[timid bronze]

they counted it in my dms bruh

[thorn wren]

And I used to get flamed for changing mine every few months 😭

[jagged forge]

i got flamed after changing mine after 8 or 9 years

everyone hated it immediately

[coarse bridge]

bffr 🥀 #discussion message

[velvet dagger]

"used to" we can change that

[jagged forge]

then i landed on this one which everyone seemed happy with

[velvet dagger]

You just said no space debris

[coarse bridge]

LMFAO

[thorn wren]

Tbf I'm flaming a friend for changing theirs for the first time in 5 years. I literally can never find our dms because the new pfp is a different colour

[coarse bridge]

with space debris it's higher then i suppose

[timid bronze]

this is all ill show in the video.

[velvet dagger]

LMAO

[jagged forge]

is that a duck with hair 💀

[timid bronze]

that s my friends roblox avatar

i put it on for like 2 mins

[jagged forge]

thats definitely higher coded

[velvet dagger]

Tru it's good

[timid bronze]

Ok i went back to that name just for u

[fresh comet]

I have a certain taste in usernames too

if you found my alt accounts, you'd probably notice a trend

[timid bronze]

If higher likes my name i am content with life

[fresh comet]

I like that name too 🤍

[timid bronze]

lastforever

THANKs

[thorn wren]

I have the "I started using discord, then stopped and when I came back a few years later I just made a new account, but still have the log in for the old one" alt

[jagged forge]

bro didn’t even commit to the bit. change ur real username smh

[true zinc]

who are you

[timid bronze]

hes obsessed with me

[timid bronze]

im chipotle

[jagged forge]

ah, so is your alt your main now

[true zinc]

isn't this chipotle

or

[timid bronze]

no

i am

[true zinc]

am I fucking stupid

[timid bronze]

thats ally

[flat harbor]

the more u hate on him the more u inflate his ego

[jagged forge]

ummmm

[true zinc]

I am so confused /g

[jagged forge]

this is a bad idea

[thorn wren]

Yeah, I mainly use the other account to send first years nlab articles to be helpful

[timid bronze]

ok wait im actually ally 😭

[flat harbor]

im not blo

not blo

[timid bronze]

bc u r

[flat harbor]

lmfao

the situational evidence

[coarse bridge]

😭

Like can we be so fr

[timid bronze]

U COPIED MY NAME MF

[coarse bridge]

?

[timid bronze]

ok.

[latent edge]

who tf is chipotle delulu world

[coarse bridge]

Ally

[jagged forge]

thats what i try to tell everyone smh

[latent edge]

oh i have them blocked

[coarse bridge]

😭

[jagged forge]

how did he react to u

[flat harbor]

blohahaha

[timid bronze]

@velvet dagger

[jagged forge]

oh wrong chipotle

[timid bronze]

wait so what songs can u relate to

[flat harbor]

theyre still not even the age for legal drinking

[timid bronze]

Some ppl just really want attention so i wonder if u can relate to it

[jagged forge]

crazy

[flat harbor]

i think this little theatre of theirs is all they have

so iguess i shuld be less dismissive of it

[latent edge]

chipotle is one of the people who's hard to block

at least for me

idk

[flat harbor]

be someone who never blocks

it grants you mysterious powers

[latent edge]

i remove block for a while when the said person gets less annoying

[fresh comet]

as somebody with an empty block list, I can confirm I have mysterious powers

[flat harbor]

chats been cleared of the sub 21s, peace and quiet

[latent edge]

most of my blocks are uhh

trolls

[flat harbor]

the thing is

[timid bronze]

I mainly block ragebaiters or disrespectful ppl

[flat harbor]

if a troll is flooding chat to the point where u need to block them

u cant rly have a proper convo in that chat at that moment anyways

[thorn wren]

I tend to block annoying discord bots

[timid bronze]

i might block an ex if i need to move on from them but i tell them that

[thorn wren]

Mee6 was on my block list for a while

[timid bronze]

but i do eventually unblock them

[jaunty ibex]

Which one am I ally

[flat harbor]

so u just gotta turn off discord for a while and come back later

[jaunty ibex]

Am I disrespectful?

or a ragebaiter

[flat harbor]

ure a staple cereal

[velvet dagger]

Hmm good question. I don't listen to enough songs to have one personally relating very much to me

The one you mentioned I can definitely see

To me personally... I gotta think

[flat harbor]

if i had to choose a staple cereal to be id be barley

[velvet dagger]

If she has you blocked, don't try to make a thing out of it

Just accept the block and move on

[thorn wren]

A perk of staying friends with an ex I dislike on discord is when I get drunk I can change his friend nickname to be silly things

[latent edge]

I've been saying the same thing for a while now

[velvet dagger]

Insisting someone explain it to you is the perfect way to make them not want to change their minds

[flat harbor]

mofo got the cadence of the downvote faq copypasta

[timid bronze]

Ou

[jaunty ibex]

Oh well i lost respect to ally

[timid bronze]

Some of my friend nicknames r criminal

like sus

😭

[thorn wren]

I used to do that. I then started as a bit following the formula of [adjective] [fruit]

[flat harbor]

does anyone wanna hold my hand thru alg geo for mirror symmetry stuff

[thorn wren]

So some examples are "Hopeful Tangelo" "Peaceful Lime"

[jaunty ibex]

I would

[flat harbor]

yay

[jaunty ibex]

I'm curious

[timid bronze]

Mine can get bad or its like smth u wont understand

[thorn wren]

You just do what the lecturer for the mirror symmetry course I took did and simply get another faculty member to cover all the alg geo stuff because you don't want to learn it

[timid bronze]

Cuz its an inside joke

[flat harbor]

i dont wanna learn it either thats the thing

[jaunty ibex]

@latent edge one more thing and I'll shut up. Is ally blocking u

[flat harbor]

so i need an "another faculty member" to hold my hand thru it

[fresh comet]

I suppose I should be grateful I only have a silly nickname then

[timid bronze]

Hei hei

no i wouldnt do that to u

i like ask my friend if they mind it

[fresh comet]

like professional monikers

[latent edge]

bro you say this and still whine about someone blocking u

idk i never cared

i can check

[timid bronze]

i wouldnt give such a name to a friend if theyre not like this yk

[flat harbor]

or mayb ill just try to read the mirror symmetry book with no bg. see if the book can carry me thru

[thorn wren]

Before he gave up I remember he had to define what a sheaf was and proceeded to define it incorrectly

[flat harbor]

damb.

[latent edge]

yes she is

[flat harbor]

thats how things are iguess

[velvet dagger]

Alright everyone let's move on from the blocking topic

[jaunty ibex]

Ok I know why she blocked

Ill stop

[latent edge]

bloe why alg geo?

[thorn wren]

They were inspired by like games with autogenerated names. Another perk is you can copy and paste funny dms to send people without necessarily identifying who sent the funny message

[flat harbor]

mirror symmetry "requires" it

[latent edge]

just do it without alg geo

[velvet dagger]

Vero if people are gonna block you don't make a thing of it or try to publicly speculate or subtweet or whatever, Deltoid you don't need to broadcast to the group who you blocked or why, etc to everyone

[flat harbor]

whenever u read the sentence "physics requires math" tho u need to hyperanalyse the sentence like ure jordan peterson like what does require mean? what maths do they mean exactly?

[thorn wren]

Like all the examples of mirror symmetry we know work tend to be certain varieties

[latent edge]

move on

speaking of alg geo

[velvet dagger]

Exactly what I'm saying to do lol

Don't wanna deal with this conversation again

[latent edge]

I saw a scheme theoretic viewpoint of unipotent matrix and I was like

[flat harbor]

weve already moved on dami anyways i was sent a big buff pdf to read

[timid bronze]

what in the mind games

[flat harbor]

id read it but my thick ass promised the kids that id make dinner all week

why did i do that

[latent edge]

bad choices tsk tsk

[flat harbor]

its day 3

and i already feel drained

i have blo burger pics tho ping in dms for blo burger pics

[latent edge]

I hope I never see the group scheme viewpoint of unipotent matrices

awful

[ocean harbor]

blo burger

[latent edge]

borgar

[ocean harbor]

ALL GD PLAYERS PUT YOUR HANDS UP

[latent edge]

real

[ocean harbor]

:v

[true zinc]

See none of this shit makes sense to me because visualizing the complex plane gives me a headache so I have no intuition for any of this shit so even if it is trivial, I don't get the full picture

[jagged forge]

visualizing the complex plane? or visualizing complex functions

if you mean the latter, i feel like the color plots work pretty well

[true zinc]

colour plots only confuse me more, one sec lemme get an example

Viewing Re and Im separately feels so...eugh

I will admit, a lot of my issues with CA are purely because I suck at arithmetic and algebraic manipulation and visualizing this shit

AKA I have terrible skill issues

[jagged forge]

hmm

[true zinc]

Like I CAN plot it

but I can't get what it means nearly as easily as I can with real

[jagged forge]

you can do both at the same time can't you. i thought usually you do color = arg(z), intensity = |z|

[latent edge]

I know this is a meme but this is a dumb meme

[true zinc]

Huh...

I did not know tis

Now I wish I did CA last summer during my break

but now I can't bc I'm busy with theory of comp

and numerical analysis

[latent edge]

Complex analysis is "trivial" as an undergraduate cuorse

[jagged forge]

yea maybe i am too eager about meming on CA tbh

considering that i don't know any

[latent edge]

smh wasting time on theory of computations when you can learn peak

[true zinc]

Yeah then I stare at the book for hours wondering why everything works so nicely, then I look it up and go "what the fu-"

[true zinc]

it's called being a CS major

smh

[latent edge]

I am a CS major as well

I won't be taking theory of comp

(well partly cuz its not required for double major)

[true zinc]

smelly smh

[ocean harbor]

i quit cs

[latent edge]

based

[true zinc]

what do you do now?

[ocean harbor]

bme

[true zinc]

but yeah also based

[latent edge]

based

[true zinc]

what's bme?

[ocean harbor]

biomedical engineering

[true zinc]

ahhh

super fucking based

holy

[ocean harbor]

the only reason i quit cs is because my classmates and professors i had last semester were lowkey replaced with ai

and pretend its MY CODE

[true zinc]

That's

so

fucked

yikes

[ocean harbor]

yeah i didnt get internships either

[latent edge]

now i have less competitions for internship

no jk i dont give a fuck

[ocean harbor]

real

[timid bronze]

@deep mango

just had my night shower

Now i smell delectable

❤️

U prob reek af

[velvet dagger]

Delectable is crazy work LMAO

[timid bronze]

But i do smell delectable delightful divine

[velvet dagger]

Quality sequence of adjectives

🤣

[timid bronze]

Ok and u never had birria in ur 27 years of living here

u had to tell ur mfing ass to get up and try it

Speaking of 27

Ur 28 so soon

U old af.

Wait i just realized ur 8 years older than me

WHAT

I THOUGHT U WERE 7

[velvet dagger]

28 is the optimal age as of around a month from now

[velvet dagger]

LMAO

[timid bronze]

i still act mentally older than u

[velvet dagger]

WHAT

[timid bronze]

I DO.

[velvet dagger]

Lying isn't acting mentally older than me smhing my head

Just because I still have whimsy and joy doesn't mean I'm not acting 28-eps fr

[timid bronze]

i dont lie

[timid bronze]

u act 9 somedays

[velvet dagger]

This message directly contradicts the previous one

[timid bronze]

i am saying u act 9 somedays

i dont even understand ur msg

u speak like chatgpt a lot

thats whjy its hard to decipher u

[velvet dagger]

Yeah I know. My point is that you can't say "i don't lie" and then follow it up with a lie

[fresh comet]

yeah, you know how to act with class when it really counts

[timid bronze]

btw dami out of curiosity

when do u think its acceptable to lie

[velvet dagger]

Thank you higher! <3

[fresh comet]

this is why I think you behave very maturely

[velvet dagger]

Hmm... It's a bit intricate

[timid bronze]

no he acts 11 in my dms

Maybe i just have that aura

[velvet dagger]

Like I guess there are kinda two sides to a lie. What consequence you intend to result from the lie, and the degree to which you compromise the trust of the person you're lying to

[fresh comet]

not Dami, but I'd probably set a lower bound on acceptable lying for the situations where it would hurt the other person physically/mentally/emotionally or their relationship with you or others more if you didn't lie

[fresh comet]

I had a clever retort to this, but I feel like it's kind of mean and now I'm hesitant to use it

[timid bronze]

Did u wanna elaborate a bit because

sometimes the things u want in life is behind a hard conversation

[latent edge]

omg this book is so good

THIS AUTHOR IS SO GOOD

[timid bronze]

and sometimes the things we tell people

is going to hurt

[timid bronze]

yeah

[velvet dagger]

Yeah oftentimes the ideal answer is, hey I want you to be able to trust that I will respond appropriately to you even if you're being truthful and the truth is heavy

But then how much can reality differ from that

[timid bronze]

for me, it kind of depends. if its for their safety, ill go with a white lie. yes, ill still call it a lie, because it is, but it's done with good reason. if its not about safety, i think id be honest. i'd just be careful with how i say it

[velvet dagger]

That's probably a good approach yeah

[jagged forge]

imo it is not only about compromising their trust because many people (at least think they can) get away with lies without the other person ever finding out. the other problem is you undermine future communications on the same topic if you tell lies

[velvet dagger]

Oh I'm not thinking compromise how much they trust you

But breaking the trust implicitly

[timid bronze]

i feel like it depends what they lie about to me

[fresh comet]

yeah so, on the first part, I might find it acceptable for a parent to lie to their child about their grandparent's passing to not cause emotional pain to the child, or for a somebody to lie in a group project about their negative feelings towards the others members so retain cohesion, and so on

the second part is

dangit

fat fingered

[timid bronze]

if they lie ab going to the bathroom and not the drinking fountain i could not give a shit

[velvet dagger]

The thing is, I'm trying to imagine a case where there's a strong benefit to lying but it's also not that big of a breach of trust and I'm somewhat struggling

[fresh comet]

let me write up the second part

my apologies

[timid bronze]

but if they lie about idk

in a way thats betraying

im going to be upset

[jagged forge]

as in that they trust you will not lie to them?

[velvet dagger]

Yeah

[timid bronze]

i feel like thatll just lead to resentment in the child

[velvet dagger]

Usually in cases where the breach of trust is kinda small, it's like well is there even much of a need to lie here?

[timid bronze]

"u lied to me this entire time?"

that happens a lot to adopted kids when they never get told they were adopted and they get frustrated w the parent about that

[velvet dagger]

Oh yeah that's a dicey situation

Like I can def imagine how it spirals out of control

You don't say it right away because they're not ready or you don't want them to feel like they're not your real kid, but then there's no great time to broach the topic without them getting shocked, etc

[timid bronze]

yeah

this society makes it seem like theyre not ur real kid lmfao

[fresh comet]

actually, I'm going to take back what I said about the second thing, because I think the bound ought to be lower than that

[timid bronze]

meanwhile we got terrible ass parents out in the wild and "Yes thats their kid bc they share the same blood" like shut up please.

blood doesnt matter

[velvet dagger]

Yeah exactly

[fresh comet]

you have a good point

[velvet dagger]

If anything, being adopted by a loving family means they chose to love you

While sometimes biological parentage is just, whoops someone's alive now

[fresh comet]

maybe I'll reduce my position to: if lying keeps the other party safe physically/mentally, then it's most likely acceptable

that seems like a good lower bound

[velvet dagger]

So it is quite unfortunate that such a weirdness exists around the I've. But then it does, and that's something that adoptive parents wrestle with. Sometimes they do it by lying and while it's understandable, it's risky

[fresh comet]

I think there are other situations where lying is okay, but I'd probably say it's case dependent beyond this lower bound

[velvet dagger]

Yeah probably

[fresh comet]

dependent on how deep the lie is, how many people it involves, etc

I have an irl friend who like
