Context?

What have I done?

thejonymyster

cant tell if youre memeing, could totally believe that it's actually displaying both names as steggan for you

but on my screen i see both stefgfgan and seggan in that message

DialFrost

@Sʨɠɠan nice!

Sʨɠɠan

@thejonymyster ik

Seriously you changed your name?

DialFrost

02:43

Where's xnor?

btw

Sʨɠɠan

@py3programmer why not

DialFrost

02:58

Anyone see xnor?

ah his profile shows he's online sometimes

but rarely

Sʨɠɠan

03:37

@py3programmer why not

@Sʨɠɠan it always loads instantly for me /shrug

py3programmer

03:52

@DialFrost speaking of xnor i think he's dead

as in, activity dead

@Sʨɠɠan i cant pronounce it

hey @lyxal do ya mind checking your scratch profile

lyxal

I think

py3programmer

CGCC-lyxal

something like that

i sent a message

ok this is neat

lyxal

My code golf scratch account may only be 2 years old, but I've got accounts out there that are 8 and 9 years old

And no, I'm not telling you what they are

That'd be doxxing myself

py3programmer

yeah right

lyxal

Because they just happened to be accounts I made at primary school

py3programmer

04:35

I have 48 followers against 3 followers

@lyxal even my account was made in primary

lyxal

I figured that much

py3programmer

but it seems 3/4ths of scratch is uninterested in code-golf

perhaps thats why

In any case, the people who follow me are jerks

the pfps are quality-less

DialFrost

@py3programmer :3

py3programmer

yeah ik

since i dont make codegolfs on scratch ig thats why ive 48 followers

hey hold on a minute @Sʨɠɠan was Steffan! I thought it was Seggan

thats why Scratch doesn't allow us to change usernames

@py3_and_c_programmer 99/100 programmers in any language are uninterested in code-golf

py3_and_c_programmer

thats true

im wondering if i wont get a job because my code is inelegant

mousetail

Yes

Get a job first code golf later

PyGamer0

@lyxal writes regex to search your old accounts

py3_and_c_programmer

only... ill do that later

mousetail

Or at least make sure you have a few portfolio pieces that are actually high quality

py3_and_c_programmer

07:13

@mousetail i do, but they're too basic

mousetail

That's fine, they are only there to distract from your really bad projects

py3_and_c_programmer

oh

In any case, companies are focused on "future performance"

Whatever is done in the past is only to hire you

if your code is confusing, you're fired

why whitespace exists

mousetail

Yea that's why you want have the first visible project on your github have good code. Even if it's a very small project

py3_and_c_programmer

Well its 115 lines

github.com/rizwan342/MyProjectRepository/blob/main/strfilter.py

mousetail

I see everything has docstrings, that's a big plus already

py3_and_c_programmer

@py3_and_c_programmer but your code is not confusing

i can read it

py3_and_c_programmer

its large tho

I posted it months back, and i have no idea how it works

oh then it's a problem

PyGamer0

why do you append or prepend :3 to almost all of yohr messages now lol

py3_and_c_programmer

like i told ginger i h8 acronyms

mousetail

There exist python versions that are not case sensitive? WTF

py3_and_c_programmer

i thought

idk, jic

PyGamer0

CMC: Dialfrost simulator (sequel to caird simulator) : Append / Prepend (50% chance for each) :3 to the input string 90% of the time.

mousetail

I highly doubt such versions exist, except when running on super old hardware that predates ASCII

(Which obviously wouldn't be able to run python anyways)

Unrelated String

yeah what

even if there were a case-insensitive mode or something there is NO way it would affect string literals

but i don't think there is any such thing

mousetail

It's checking the equals operator: if 'LoRem Ipsum' != 'Lorem Ipsum': # only difference is that 'r' is lowercase

Unrelated String

oh yeah it could be testing the internal logic

i sort of assumed the idea was something for case-insensitive identifiers in source code but i guess that's not too absurd either

py3_and_c_programmer

07:33

yeah

i was too dumb then

tooo dumb

cause i was paranoid about code that was incompatible

mousetail

Seems like quite some complex code for something you didn't know was needed. I'm lazy, only add those things when someone complains

Unrelated String

py3_and_c_programmer

im not

im paranoid

and im py3_and_c_programmer

and you're @mousetail

oh wait py3.10.8 released gotta go download it

@emanresuA sneaky sneaky

btw @emanresuA is your profile an overlay of the rainbow and a random generated pfp from SE?

or what?

Brain teaser. Find the real number x that solves 4^x + 6^x = 9^x

(you can use code)

lyxal

emanresu A

10:53

Took me a while to figure that one out

DialFrost

11:03

@graffe damn thats abit tricky ish

but interesting math question either way

graffe

Thanks!

Now the question is, can it be solved by any open source system?

PyGamer0

@lyxal how did you get that?

graffe

@lyxal you win!

lyxal

@PyGamer0 symbolab.com/solver/step-by-step/…

graffe

@emanresuA you might be the first one to do it by hand

emanresu A

11:14

It's not particularly hard once you figure out how

graffe

Like much of maths!

emanresu A

spoiler

graffe

@emanresuA that makes it much clearer

Are there really no open source systems that can solve it?

Open source needs to catch up!

lyxal

sympy didn't like it

graffe

Maybe sympy/sage?

@lyxal :( I like reporting "bugs" to sympy

I guess it's really a feature request

lyxal

11:17

well it wasn't a "bug", it's that it just isn't implemented

graffe

@lyxal yep

But it can be good for developers just to know that users care

PyGamer0

11:47

@graffe ~~lets make one~~

graffe

@PyGamer0 why delete it?!

PyGamer0

@graffe i can't make it :P

graffe

@PyGamer0 it could at least be a challenge here

What would you call that type of equation?

PyGamer0

12:04

@graffe exponential equation?

graffe

@PyGamer0 sounds plausible.. let me google that :)

issue opened for sympy :)

PyGamer0

@graffe link ?

@graffe ~~or i can make it but~~ (sounds too complex, but it might be fun to attempt lol) i don't have enough motivation

lyxal

github.com/sympy/sympy/issues/24138

If I had a nickel for each time I did something with sympy that lead to graffe opening an issue on the sympy repo, I'd have two nickels, which isn't a lot but it's weird that it's happened twice

graffe

@lyxal :) I am cheering sympy on even though it's never going to be great because it has about two developers

but I hate the idea that there are things you just can't do in open source

PyGamer0

@graffe two!!!

just two

graffe

12:18

give me more issues to open!

hmm.. github.com/sympy/sympy/issues/23207

sympy is not in a good state :(

mathcat

If I had a nickel for every time I had to publicize confidential information to host a website on Github pages, I'd have three, which is a lot compared to my empty wallet.

graffe

rich beyond your wildest dreams!

it turns out I am not sure how to prove that a^x/b^x = (a/b)^x in a simple and intuitive way :(

any ideas?

mousetail

That's just the distributive property right?

graffe

can you expand that a little please?

mousetail

Like that's just the definition of the distributive propertly

it's a identity, you don't need to prove it

graffe

12:31

a(b+c) = ab + ac is the distributive property to me

mousetail

This is the exact same thing

Except with multiplication instead of addition

(ab)^c=a^c*b^c

graffe

13:08

good point

Does somebody know a good maths scratchpad app with features like pasting images, writing equations, etc.?

Radvylf Programs

That's actually something I've wanted for a while too

Any time I need to write down math stuff on a computer I usually default to either using programming syntax (inefficient and too many parens) or using a pencil on the lid of my laptop

mathcat

exactly

programs like wolfram alpha aren't much better either

I've been using ipython ever since

whitespace mostly instead of parens

Well I've decided that I'm compromising too much cool stuff by using floats, and limits of rationals have their own major issues, so...time to reimplement SymPy in Rust

hey i have a RuntimeStuff class in one of my projects. 100% formal

Radvylf Programs

@lyxal Vyxal uses SymPy right?

How do I enable that?

The default seems to be floats on the online interpreter

Also, I'm starting to think I'm overthinking the "representing numbers as limits of rationals would make equality behave weird" since...

Floats don't exactly not do that either

Well okay now it's sympy. Guess google lied to me.

lyxal

22:19

lyxal.pythonanywhere.com is 2.4.1 - the last stable version before 2.6. It doesn't use Sympy

vyxal.pythonanywhere.com uses the latest version which does have Sympy

Radvylf Programs

ah. Google must've had that one as its first result then

lyxal

It does

That's why you should use DDG

It has the latest interpreter first

Or maybe you should do better SEO ;p
