I need to stop doxxing myself lol

Unrelated String

how much more can you even

Rydwolf Programs

I posted something that contained my phone number on an insta story by accident and one of my followers texted me but I can't tell who lol

Unrelated String

oh

wow

Rydwolf Programs

Oh IT'S THE GIRL lmao

lyxal

good job bingus

:p

Unrelated String

00:32

PFFFFFFF

Rydwolf Programs

I find it kinda funny we never got each others' phone numbers throughout all that lol

Unrelated String

yeah wait what

how were you texting with her

Rydwolf Programs

We never bothered since she's Android and I'm Apple

Unrelated String

just discord?

Rydwolf Programs

Insta

Unrelated String

00:33

i was about to ask if it was some weird shit like twitter dms lol

i can never remember that the social media platform that's about images lets you send text to people

Rydwolf Programs

Insta's great it's perfect for just keeping up with your friend group/community

lyxal

Unrelated String

wait so does it have group chats too

what

lyxal

thanks vs code

Unrelated String

why is it even called instagram at that point

lyxal

00:34

for autocompleting my <div> with a </button>

Unrelated String

naturally

all divs are buttons at heart

lyxal

I blame svelte having funky button onclick binding

@UnrelatedString as are <h2>s

Unrelated String

AAAAAA

Rydwolf Programs

@UnrelatedString Yeah (tho that's not was I was referring to, more just the format of the app works great for keeping up with people you know)

Unrelated String

wacky

lyxal

00:36

@UnrelatedString and <ul>s

Unrelated String

naturally

Rydwolf Programs

As I always say, if you can click it, it's a button

lyxal

ah I see what's happening

vs code is linting my button definition to be multiple lines

but then it gets confused because it doesn't realise the button definition is multiple lines

A+ linting

Rydwolf Programs

omfg I am not letting her get in my head again

She remembers the exact day we met

Like me

lyxal

I sure love how aws lambdas require zip folders

I also love having to write a python script to automate lambda deployment to localstack

Unrelated String

00:55

@RydwolfPrograms wow

Rydwolf Programs

And what makes it worse is that day happens to be valentine's day

att

:o

Unrelated String

tbf

that also makes it less impressive to remember :P

ATaco

@lyxal Clearly they parsed HTML with Regex

user

01:15

You joke, but VS Code does use regexes for tokenization, right?

Yeah it uses TextMate grammars, which are just regexes (iirc) (don't quote me)

@RydwolfPrograms Rydwolf, haven't you asked this guy out yet? Just do it and stop torturing yourself

lyxal

I have created the most jank localstack workflow

ATaco

You can use Regex to tokenize HTML. But Tokenizing isn't the same as Parsing.

user

Oh, right

Ginger

@user the LSP can handle tokenization/parsing itself, fwiw

user

Yeah, but it's slower

You need syntactic highlighting first and then the LSP can add on smarter semantic highlighting

iirc, Scala does that (separate Scala Syntax and Metals extensions, I think?)

Destroyed

Ginger

01:21

@RydwolfPrograms pfft

genius

shame you presumably deleted it, otherwise I could text you myself :p

user

How do we know that you weren't the person who did text Rydwolf?

Ginger

you don't :3

lyxal

okay so here's the rundown:

1. Start svelte frontend
2. Start localstack with every possible CORS check disabled
3. Run a python script that zips every file in a "lambdas" directory into its own zip folder ("LambdaHandler.py" -> "LambdaHandler.zip")
4. Run a python script that converts every zip into a Lambda instance
4.1. That python script then generates URLs for each Lambda. Each Lambda URL is sent to a pythonanywhere webapp that stores a map of LambdaName -> URL
5. The Svelte app (and also the lambdas themselves) get the API URLs from the pythonanywhere server before actually making an…

it doesn't sound too bad, but it kind of is given how many things are being hacked together

Ginger

no, it sounds quite bad

you've one-upped the v3 deployment system :p

lyxal

and all to test locally what will inevitably need some changing to make work in actual AWS

for example

    let clickHandlerAPI = "";

    fetch("https://URL STORER/get?url=ClickHandler").then(
        (response) => {
            response.text().then((data) => {
                clickHandlerAPI = data;
            });
        }
    );

that's in the svelte to get the link to the dynamically generated url for the ClickHandler lambda

user

01:26

Are you sure there isn't an official guide that has an easier alternative to this?

lyxal

how will my frontend components get the links generated in a session?

apart from manual copy-paste, the svelte has no way of knowing what the lambda url will be

if this were real AWS, the Lambda URLs would stay the same

because they'd be constantly hosted

they are not constantly hosted in localstack. If I close the terminal/restart my computer/close docker/etc, I'll have to regenerate all the lambda functions anyway

also, hot reloading is only for localstack pro subscribers

user

Aww

lyxal

so when I want to make a change to a lambda, I have to reroll the url anyway

so I might as well make a system that can dynamically store the lambda URLs as they're created

Rydwolf Programs

02:28

@Ginger Nah I don't care enough to delete it lol

If you want to go ahead :p

Rydwolf Programs

03:09

@user Which guy?

Rydwolf Programs

03:29

I don't think my TNB loaded right

I'm curious what that "message batch operations" thing is...maybe some sort of old version of the move tool?

Or is that a mod tool?

hyper-neutrino

it's just the move/delete tool lol

Rydwolf Programs

Interesting

lyxal

03:46

You can also tell it's the RO variant because there's only the relocate button and not the delete button

So not a mod tool

CMC Given two tempertures, decide how much heat taken for 1kg of H2O from one temperture to another. 0 mean water at 0 ℃ while -0 mean ice at 0℃.

Rydwolf Programs

04:01

They found the helicopter

ATaco

@l4m2 Isn't this just the difference? What am I missing here?

l4m2

@ATaco Ice have different heat capacity than water

ATaco

Yeah but heat doesn't exist as a unique unit of energy, per the challenge spec. How much energy it would take is a slightly different question

Otherwise the answer seems to just be (b-a)+(a<0?80:0) kcal

Rydwolf Programs

05:18

Okay I just realized something incredibly cool

I'm representing a chess board as an array of 64 squares, and positions as ints from 0 to 63

And if a piece makes any linear move of N spaces on the chess board, you can divide that move into N increments/decrements of a constant value

Since if it's horizontal you just increase/decrease by 1 per space, if it's vertical you increase/decrease by 8 per space, and if it's diagonal, you do both, which is an increase/decrease of either 7 or 9 per space

I wonder if there's a formula you could use to calculate the number of squares moved just given the source and destination indices

abs(src - dst) or abs(src // 8 - dst // 8) would work actually

ATaco

CMC: Prompt golf. In an LLM of your choice, have the engine say the words 'hello world' consecutively with any amount of punctuation. Eg. "Hello, World!", "Hello world", etc. Smallest prompt wins, does not need to be easily recreatable, though evidence is required.

@RydwolfPrograms Knight

Rydwolf Programs

Yeah just for linear moves I meant

lyxal

@ATaco only hello world or can it be in a block of text

ATaco

Can be as part of a block, though must be consecutive

mfw i'm testing serverless stuff and I forget to update a frontend component to fetch the right api and wonder why it's 502ing

I just made a clicker game in the most stupid way possible

using serverless architecture, api calls and aws lambdas

absolutely no local js calculations

Is this too complex for Mathematica to solve?

Bubbler

06:30

@l4m2 you might want to ask it on Mathematica.SE

l4m2

With basic knowledge to such, what ratio of people can solve it?

Bubbler

I don't get your question

with basic knowledge of what?

l4m2

of integrate and derivative

Bubbler

Idk how it even relates to integration

l4m2

I solved using integration but maybe that's unnecessary

or knowledge of limit

Bubbler

06:54

hmm, so the sum is upper bounded by integration of the function from 0 to n and lower bounded by 1 to n I think? Both of which Mathematica does solve with Integrate in a minute

tio.run/##y00syUjNTSzJTE78/…

I guess Mathematica takes too long to figure out that converting to integration works, or it is simply not implemented and it is the job of the user

Rydwolf Programs

07:21

Been coding for 9 years and just had a bug thanks to (a or b or c) in list >:|

I really like the lang (Perl?) that lets you do x == y | z, extending that to x | y in z would be pretty natural (if perl doesn't already have something like that) and I think both of those are solid syntax sugar to include in a language

I also wrote if x == -4 or x == -4 (supposed to be -4 or 4) which I also feel would be a harder mistake to make with that syntax

att

mathematica has (x|y)∈z, but asserting x,y are both in z

(and of course ∈ doesn't work with lists on the right anyways)

Rydwolf Programs

Oh no...fuck...not again

I think I found a bug in a programming language

Python's doing some weeeeird stuff and as soon as I log two bytearrays it fixes it

I'm getting war flashbacks to the time my JS was bugging out and adding logging fixed it and it turned out to be a chrome console bug

Okay phew it looks like it's not actually the logging that's causing the nondeterminism, so something's still very broken but it's not that

lyxal

What's going wrong?

Rydwolf Programs

If I capture a piece, sometimes the piece remains the original, but all of my logging in the move/capture code shows the function ending with the proper piece being placed in the proper square

omfg

it's a front-end issue

I checked earlier but I must've misread it

Rydwolf Programs

Oop found another in the original implementation lol

I like fuzzing

At least it's called fuzzing and not furring

lyxal

Fuzzing is a good thing

Aaron found a few vyxal 3 bugs using it so I can attest to its usefulness

Topical given fuzzing is part of the software verification assignment I'm doing :p

Bubbler

yeah, one particularly good use case of fuzzing is fuzzing compilers/interpreters

2024 Varzaqan helicopter crash

On 19 May 2024, a Bell 212 helicopter crashed in Bakrabad Rural District, near Varzaqan, Iran, while traveling from the Khoda Afarin Dam to Tabriz, killing all five passengers and three crewmembers. The helicopter was carrying the president of Iran Ebrahim Raisi, foreign minister Hossein Amir-Abdollahian, governor-general of Iran's East Azerbaijan province Malek Rahmati, and the representative of the Supreme Leader in East Azerbaijan Mohammad Ali Ale-Hashem. Raisi's head of security and three members of flight crew were also killed in the crash. The crash took place in Iran's East Azerbaijan province...
