[solemn tulip]

using range vs direct comparison is not that interesting of a question when both have the same time complexity anyway

this algo is nowhere near the stage of constant factor optimization

[little sky]

Yeah true that but I personally haven't seen range being used in this way and the comparison looks explicit and clear.

[solemn tulip]

idk, the range is as explicit

[crystal spruce]

why are we excluding m == 0 tho

[solemn tulip]

idk why that was changed

[little sky]

The problem states m,n are natural numbers.

[crystal spruce]

do you take the convention of 0 not being a natural number?

[little sky]

Yeah 0 is a whole number but isn't natural.

[solemn tulip]

you let n include 0 but m not, so at least be consistent

including 0 in both won't really change much

god, why am I trying to solve this in closed form

like, the initial stuff isn't that hard to find out

def repunit(n: int) -> int:
    return int('1' * n or '0')

def repunitsum(n: int) -> int:
    return (repunit(n)*10 - n) // 9

n = 99
sum1 = 7*repunitsum(n+1) - 2*repunitsum(n-1)*10 - 7
num2 = 7*repunit(n+2) - 2*repunit(n)*10

but expanding and trying to massage stuff...

[crystal spruce]

I represented it as 7000... + 555.... + 7

[solemn tulip]

that's...a wiser choice

[crystal spruce]

that way your summation index can range from 0 to n-1

[solemn tulip]

oh well, I'm in too deep already

god, it's all repunits

[crystal spruce]

which is nice

[polar merlin]

hi

can anyone help me with a bash issue

i'm trying to run a python app that i create with bash

bc it wloud be faster

but it gives me this error

[solemn tulip]

I mean, I have a diophantine equation

n*(68*r(N+1) - 81 + 13*(N+1)) - 9*m == 81 + 9*68*r(N+1)
```but it's not exactly nice 🥴

where r = repunit

[crystal spruce]

my working was just this

[solemn tulip]

It's almost like you picked nicer primitives 😛

oh wait, your S is not nice, is it?

I guess my form will boil down to expanding that S

ok, I guess this isn't that terrible when inserting 99

(n - 9)*(68*r(100) + 1219) - 9*(m - 1210) == 0

but still

I don't think I'll get any closed form solution

compute the numbers, solve the diophantine thing to get the solutions

should be like O(log something)

[brazen ingot]

yeah I have did this before by hand

well imma go sympy simp again

[little sky]

Yeah true that but n in any case can't be zero. It was included just to keep the code short but you are correct.

[limpid lynx]

whats your best submission yet?

[little sky]

113 bytes

[limpid lynx]

so its a draw between yours and ms. take?

gift yourself the pizza

[little sky]

by @acoustic moss

Will give it to him only I can have anytime lol. Also great try @crystal spruce, the approach was neat.

[limpid lynx]

this tells us people on twitter arent very smart

[little sky]

This is really a great simplification.

[little sky]

Yeah no submissions via twitter just views only.

[crystal spruce]

i did that at first, but i didn't generalize to n, and then i just threw in the towel and did the modulo argument

should've continued

[little sky]

You should checkout the full paper, pretty interesting problems: https://jeeadv.ac.in/past_qps/2023_1_English.pdf

Can someone recommend a good laptop that doesn't cost too much which is good for a software eng/CS university course?

[mortal vapor]

try searching youtube with your budget caption
prolly that will help the most rather than personal opinions of people

[little sky]

Closing the submissions officially and declaring @acoustic moss as the winner. Let me know what Pizza would you like. Thanks to everyone else who contributed to this discussion.

[acoustic moss]

i uh

thanks for the offer but i dont think i can accept 😅

[little sky]

Whyy lol

[umbral sparrow]

@crystal spruce @little sky What math topics would one need to be familiar with to solve this? Just wanting some direction

[acoustic moss]

you have to spot that 75...57 can be written as 7*10^n + 5*10^(n-1) + ... + 5*10 + 7 and then you have to recall the formula for sum of a geometric progression

[little sky]

This particular problem is part of Sequence and Series. But you will need various other concepts to get to the solution.

[umbral sparrow]

Thanks for the tips

[grave cove]

well i can

i'll take pepperoni with no toppings, thanks

[acoustic moss]

nuh uh

[tardy rain]

Pepperoni is a topping

[tardy rain]

Sinbad was a mythical arab sailor and whatnot

[solemn tulip]

I might have written a tad too much code to help me in figuring out the language 🥴

putting insights into code, which means that I could analyze patterns in the insights

like implementing merging of glyphs, which together with a bunch of previous collected data and a dumb double for loop cracked things for me

oh yeah, and terminal rendering of images of tunic text, with the associated latinized sounds underneath, I disabled that part for the image above to avoid spoiling too much

[solemn tulip]

I do

But apparently, the government is giving free classes for CPL

Which is super duper expensive to get

But they require you to have a degree or close to getting one.

I'm literally 1 semester short.

Because my university is on a strike

I'd switch careers in a heartbeat idc

I love aviation and flying

[vale raven]

See if you can get them to make an exception

[mystic drift]

fat chance

the signup period goes to the end of this month

and my semester ends like, two months from now (according to my schedule, it will take longer ofc because of the strike)

man what a L.

[low chasm]

you can't be a pilot if you have glasses?

[elfin holly]

I personally work by many principles, but one of them would be: "Certain words, when put in a specific order, can convince anyone of anything", the key is to know which words to choose and how to order them

so you can shoot your shot and try to register there, but make sure to choose your words carefully

[low chasm]

yeah I'd still give it a go

worst case scenario it doesn't happen, but what if it does?

[mystic drift]

You can

So long as you see perfectly when using them

@steady jacinth hey pecky long time no see, how is the notepad coming along

get to it later then when its all over

plz dont start doing that ever again

[limpid lynx]

well you better not get distracted

[wanton delta]

do you know of git mv

[vale raven]

Yes
But I always forget to use it

[solemn tulip]

git doesn't even store this info right?

iirc it kinda just figures out that files were moved by similarity

or did you just mean that avoids a lot of git adding?

with jj it's just plain mv to accomplish the same thing 👀

[gritty zinc]

I know git mv is necessary to preserve history as seen in, say, vscode

i'm not totally sure why, but I think it's because having the diff detect moved files requires a flag (it's not the default behaviour)

[solemn tulip]

I think git doesn't trace this info, but maybe I remember wrong

[grave cove]

I don't know how git would even track that

Without you telling "I moved this file from here to there"

[latent pewter]

huh

[solid elbow]

https://git-scm.com/book/en/v2/Git-Basics-Recording-Changes-to-the-Repository#:~:text=Unlike many other VCSs%2C Git,it you renamed the file.

git doesn't track moves, at all

[lime oyster]

Howdy! How do I go about writing a proof to the following lemma?

[brazen ingot]

i think abel summation theorem definitely helps here

[lime oyster]

Oh that's clever!

[solemn tulip]

stuff like mercurial does track it, and yes you need to explicitly tell it via hg cp and hg mv

iirc git does try to reconstruct some stuff like this based on diffs

[fresh basalt]

what about falafel?

Have you held falafel?

Falafel is better than gun

\

It will make you fat if you eat too much though.

Also not great to eat fried food all the time.

Which is the cruelest joke.

Because fried food is so good.

And really who wants to live forever anyways?

[tardy rain]

not the biggest falafel fan

i like meat

[fresh basalt]

Meat will also kill you.

[tardy rain]

not if i kill it first

[fresh basalt]

No, it will get you in the end.

I saw a video of an orangutan chewing some leaves and applying it as a poultice to a wound on its face.

Isn't that awesome?

It learned how to do that.

It wasn't genetic or instinct.

I'm not surprised. I just thought it was awesome.

It's easy to question an entity's intelligence if you don't comprehend its behavior.

Chimps go to war.

Chimps are more vicious than gorillas.

https://www.youtube.com/watch?v=z4BmXSBXz-c

I think the clip of the orangutan might be in there actually.

It's interesting because they patrol their territory.

Well that's one of their interesting behaviors.

They basically move quietly through the jungle stalking their territory. If they find an "intruder" they'll kill it.

[grave cove]

would you rather be with a bear or with a monkey

[fresh basalt]

What type of monkey?

[grave cove]

i wasn't aware there were multiple types of monkeys

[fresh basalt]

:O

https://en.wikipedia.org/wiki/Monkey#Classification

Robin there are so many

Bears are not dumb.

[carmine apex]

a bear can likely kill with a single swipe of its paw

Look at that little guy

[carmine apex]

there are bears that attack even when not hungry

[fresh basalt]

torturing how?

[carmine apex]

i don't think sadistic behavior has been observed in monkeys. a few aquatic species, sure

[fresh basalt]

I wonder if monkeys find it funny to urinate on people walking on the ground below.

I mean, it is.

Tell your friend to walk under a tree with a monkey in it.

I've seen videos of monkeys crawling down out of trees and playing with human children.

capuchin I think

I mean it was local natives.

South America somewhere

They are probably used to each other.

sure

I would never really try to pet a wild animal or otherwise interact with it.

[vale raven]

Why not?

[fresh basalt]

A plethora of reasons.

[carmine apex]

i mean, zoos exist, and some of the exhibits permit touching

[vale raven]

I have an entire YouTube channel of me and my dog petting a stray cat

[fresh basalt]

Stray cats are not exactly wild.

Not in the sense that a mountain lion is wild.

[vale raven]

I got to feed the giraffes at the zoo once
That was fun

[fresh basalt]

Giraffes have gigantic tongues.

[carmine apex]

some critters are also less dangerous than others. you can treat a giant constrictor with less fear than a cougar, for example

[fresh basalt]

Reptiles are dope.

When I was a kid I got to hold a long albino boa that was like 7 feet long

[carmine apex]

it greatly saddens me that a snake cannot hear itself being complimented. at best, the vocal tones might be soothing, though

[fresh basalt]

For a long time when I was a kid I wanted a chameleon as a pet but they are very hard to not kill.

So I had a dog instead.

[limpid lynx]

true, do you not let him kill or is he well behaved

[limpid lynx]

since when did github start having age restriction

[frozen crane]

I live on a non-ground floor of an apartment building. and the birds he wants to kill are on the balcony. but he can't get over the railing.

[wild valley]

Everywhere

[fresh basalt]

AFAIK online services (at least in the US) require a minimum age.

[limpid lynx]

ah i see, but in a park or somewhere with birds on the ground, he goes?

[fresh basalt]

I think that's federal law.

[limpid lynx]

i meant an upper age limit

[fresh basalt]

I could be mistaken.

[frozen crane]

no, I don't take him to parks

[limpid lynx]

not a minimum age

[limpid lynx]

[vale raven]

A 12 mile day is a normal weekend for me
5 mile route in the morning, around the block for lunch, 5 mile route again before bed

I've heavily fallen out of my routine, now I can barely get out of bed, but I used to regularly go a third time

I'm embarassed to see how far I've fallen
Now I'm lucky if my counter says 2 miles

[harsh tundra]

My normal step counts are usually 3-4k, idk the distance (I'd need to browse them day by day).
Some on the graph are skewed because I didn't wear my watch

at that point don't the "blocked message" things start to become a problem?

[paper sequoia]

I'm trying to understand cloudflare... If I own a domain, say "example.com" but don't have a vps. I should be able to use cloudflare to self host some app, say fastAPI app, but wouldn't my IP be exposed there then?

[lament cairn]

by "self-host" you mean expose it with Cloudflare Tunnel?

[paper sequoia]

Yes I guess

[lament cairn]

"I guess" - that doesn't sound like a yes to me

[lament cairn]

or do you mean making an A record pointing to your IP?

[paper sequoia]

Having something run in my own computer and exposing to cloudflare

[lament cairn]

Either way, if you set it to be proxied, you'll be protected

[paper sequoia]

I'm not too sure exactly, I was trying to understand how it all works and quite confused

[lament cairn]

orange cloud = traffic goes through CF
grey cloud = no proxying, exposes IP through DNS

when it's proxied, your IP will be hidden. on DNS records it'll show cloudflare's ip, not yours

[paper sequoia]

So there would be no way for someone to know my IP if it's proxied?

Right, what about when the app is not running? The web should be down and again no one would see my IP?

[raw orbit]

thats crazy ironic

[paper sequoia]

Hold on..? Would both hide the IP or just the proxy one?

[raw orbit]

nah nah i saw that pikachu

[lament cairn]

only the proxied one

[vale karma]

Can anyone help me with my IT homework?

[paper sequoia]

I see, and with the proxy one I should be able to have some FastAPI app running locally that would show up in my domain in way or another?

[lament cairn]

sure

[lament cairn]

unless your web app/server leaks info about itself

[paper sequoia]

Do I need any configuration to router or anything for it to work?

[paper sequoia]

Hard to say, only thing I can think of immediately is the server section which shows the server it's running in, which likely would expose the IP

[lament cairn]

there's two ways to do it

• expose your app to the internet with port forwarding and all that stuff, then set your domain's A record to your IP and the proxy status to Proxied
• use cloudflare tunnel https://www.cloudflare.com/products/tunnel/

[paper sequoia]

The tunnel would be the way to go I guess, that's the proxy one?

Oh.. I didn't see the edit

[lament cairn]

tunnel is just a way to make services available through cloudflare without having a public IP

like if you were behind CGNAT or something

[paper sequoia]

I see, so port forwarding is required. Then I likely should set up firewall rule to only allow cloudflare just in case

[lament cairn]

if you're going with the standard DNS way then yes you need to port forward

allowing only cf works, it's what I have set up

my webserver drops any non-cf connections

[thick ore]

how o_O

[lament cairn]

hold on lemme get the nginx configs

[thick ore]

nginx ⁉️

[lament cairn]

nginx‼️

[paper sequoia]

Sorry I'm very new to all this 😅
So... Port forwarding is for the DNS? But to ensure my IP is hidden I need to use the tunnel, that is going to be like the proxy?

[lament cairn]

i think i explained it badly, let me type a better explaination

[paper sequoia]

I might just be understanding things very wrong here...

[lament cairn]

both options will hide your ip
cloudflare tunnel tunnels traffic through a special service running on your server, which is why it doesn't require port forwarding
the DNS method hides your IP as long as the record is set to Proxied. for this, cf needs to be able to reach your web server over the internet with your IP. that's why it requires port forwarding

both methods will appear to the final user and in public DNS records as if Cloudflare theirselves were hosting it, but whenever someone accesses your site, CF forwards the request to your backend

[paper sequoia]

Ooh now I get it, in the end both are in that sense secure but one requires port forwarding and being sure it's set to proxied. Which one would you recommend?

[lament cairn]

Tunnel requires a bit of setup but I think it's more convenient as you don't have to touch your router settings

[paper sequoia]

That would be convenient

[lament cairn]

Tunnel runs in the background as a service

• it guarantees requests will always go through cloudflare

[paper sequoia]

That sounds good, without domain though it would not work right?

[lament cairn]

which isn't the case with IP + DNS (unless you configure your firewall to only allow cloudflare ips which takes more work and blah)

[lament cairn]

nope, you need a domain to get started with anything cloudflare related

[paper sequoia]

Ye figured, there are some record and stuff there

I think I'll try roll in to GitHub student again, to get a domain

[lament cairn]

you need to be able to change your nameserver to cloudflare's

does gh student allow that?

like, do you get a domain 100% for yourself, dns and everything?

[vale raven]

They don't give you the domain
They give you a 100% off coupon to NameCheap

[thick ore]

oh man the gh student pack

[lament cairn]

ahh i see

[thick ore]

they give you a free .tech domain with DNS n stuff

[paper sequoia]

Also one thing I'm curious about is if the request to my server comes from cf, can I see the IP of who originally requested that? If so, can I somehow block IPs there?

[vale raven]

So yeah, you get everything that NameCheap offers

[lament cairn]

yes, with the CF-Connecting-IP header

[paper sequoia]

I could also just get a domain for few bucks a year from namecheap

[lament cairn]

cloudflare is also a registrar

they're cheap. in fact, they're as cheap as it can get
the domains cost as much for you as it costs for them - no additional markup

[paper sequoia]

They might be slightly more expensive, the domains I have looked for have been in range of 1.xx - 6€

[paper sequoia]

Oh, interesting

I didn't know that

[lament cairn]

namecheap has first year discounts, then they get you with the renewal prices

[paper sequoia]

Perfect! That allows some nice setup there. Does using CF slow done the requests much?

[lament cairn]

nope

[paper sequoia]

I would likely just register for a year, so stays cheap for one tile purchase

[lament cairn]

well, technically yes since there's one more server between you and the user, but it should be minimal

[lament cairn]

the thing about buying domains from cloudflare is that you won't be able to disable cloudflare from it unless you transfer your domain to another registrar

[thick ore]

like that's a bad thing

lol

[lament cairn]

yeah lol

[paper sequoia]

So if I get from them, I'm stuck with them? But... Doesn't sound bad

[lament cairn]

exposing anything to the internet these days without cloudflare is asking to be ddosed

[paper sequoia]

I definitely need to re-do the security of my API to ensure nothing is leaked before exposing anything

[lament cairn]

it's not bad at all, just something to be aware of

[paper sequoia]

Ye, it's good to know

[wanton delta]

so it was a product of human savagery

cloudflare would not have existed had humans acted civil

[lament cairn]

yes, same for like all cybersecurity companies

[wanton delta]

good point

[lament cairn]

actually cloudflare would have existed still, they're a CDN

[wanton delta]

o yeah

[paper sequoia]

I'm still figuring out if it's good idea to have docker containers and have those exposed to or do I need to run them locally completely

And if I do docker, do I need additional setup/security wise setup

I seen some being able to pull secrets out of containers if they are ran in place x, but if the request is forwarder by cf, is the content only?

Would one even be able to do network scan against the domain, for stuff like services running in it via nmap or something

[lament cairn]

the standard setup for production is using a reverse proxy like nginx
that reverse proxy then passes the request to the container

[paper sequoia]

So it would be kind of like
Web visitor -> cf -> nging -> container and response in same but reverse

[lament cairn]

yes

[paper sequoia]

I been meaning to learn about that so this sounds good

Should I / Do I need any firewall rules there just in case?

[lament cairn]

ehhhh if you're going with tunnel no

[paper sequoia]

Sounds perfect!

[lament cairn]

you won't be exposing your web app to the public internet, it'll be a secure connection between you and cloudflare

[paper sequoia]

Right

Hmmm

And only basically the content of request is forwarded?

[lament cairn]

nmap works on ips, if someone tried they'd just be running nmap on cloudflare

[lament cairn]

content, headers, etc

[paper sequoia]

Ooh right because I'm not exposing my own network ip

[paper sequoia]

I'll need to do proper inspection on all of that before exposing anything

[lament cairn]

I don't understand. you mean someone sending a request to your web app and fetching container secrets from there?

[paper sequoia]

Maybe I should protect the /docs endpoint with basic authentication

[lament cairn]

I disable it in production

[paper sequoia]

I didn't even think of that 🥴

[lament cairn]

app = FastAPI(
        ...,
        docs_url=None if settings.environment == "prod" else "/api/docs",
        redoc_url=None if settings.environment == "prod" else "/api/redoc",
        openapi_url=None if settings.environment == "prod" else "/api/openapi.json",
        ...,
    )

[paper sequoia]

Don't remember exactly, might be just my memory tricking me. I read bunch of stuff about docker security and best practices. That was just some tool I came across in GitHub

[vale raven]

Why?

[lament cairn]

closed API

[paper sequoia]

Gotta setup some similar then, does this by any chance be in public repo?

Oh, closed API

The docs I serve allow testing the stuff directly in the browser and also show the server it's running in, so I might just close them completely

[paper sequoia]

Do you happen to have any example configuration for nginx?

[lament cairn]

simplest valid config looks like this

server {
  server_name example.com;
  listen 80;
  
  location / {
    proxy_pass http://localhost:8080;
  }
}```

[paper sequoia]

Huh, that simple

[chilly beacon]

guys suggest a good low load browser
for debian

firefox is terrible

[lament cairn]

oh, in tunnel you can specify what host and port the tunnel service should request when a visitor accesses your website. so it doesn't have to on port 80

debian? bad? no way

[paper sequoia]

What do you use for blocking IPs from accessing your API? Do you just set firewall rule to block them or just some middleware for it? If you do any rate limiting

[paper sequoia]

I see, so I can basically pick any non accupied port there for it

[chilly beacon]

[jaunty wraith]

cat!

[solemn tulip]

wdym only discord?

like, discord electron? that uses a bunch of memory on its own

if it's about discord in firefox, aren't browsers usually pretty good at adapting to your machine?

i.e. it will try to adapt to the overall load to the machine and the available resources

[lament cairn]

in my experience firefox scales well with many tabs open
where chrome/chromium's ram usage explodes with too many tabs, firefox is fairly stable

[vocal oyster]

honestly people worry about RAM usage way too much

only worry if you reach 99% and programs just aren't releasing RAM

[lament cairn]

"unused ram is wasted ram"

[vocal oyster]

yes it is, you get decent speed ups by having browsers cache recently visited things

if the RAM is unused why not use it for low priority stuff like that

browsers can clear out old tabs and have them on standby almost if there really is not much RAM

but generally it is just a non-issue

[harsh tundra]

At some point Firefox has some kind of memory leak and starts kinda being slow - you gotta kill it and start it up again

In the past (I'm thinking my high school days) it was literally a memory leak - the ram usage for Firefox would spike and slow down whole computer. Kill, start up - worked great again

[low chasm]

@acoustic fern for the most part, I didn't actively dislike RustRover - it didn't crash as often as rust-analyzer, for example. What really turned me off was the lack of being able to automatically run project wide analysis on your code, and then have the editor point out which files have those errors within the file tree, for example. It'd analyze the current file fine, but if I wanted a project wide analysis, I'd have to manually run one, and one thing I like about VSCode is that it highlights on the file tree which files have errors, so I can pretty quickly navigate to them. So, if I'm changing an API for example, I want to immediately know where in my code stuff broke, so I can jump to it and fix it. I wasn't fond of having to run the project wide analysis manually every time.

[acoustic fern]

Interesting. Is that also the case for PyCharm and other IntelliJ IDEs? (I use PyCharm every day and yet somehow I can’t remember if it would point out errors for the whole project by itself)

[low chasm]

I don't recall, I haven't used pycharm in a while.

[acoustic fern]

Fair - thanks for the review! Shall keep it in mind if I try RustRover. VSCode+Rust Analyser isn’t quite doing it for me at the moment so I’ll probably try it RustRover but keep this in mind

[low chasm]

good luck

[wraith hound]

fwiw if it's specifically vscode that won't cut it, rust-analyzer can be used anywhere that supports the language server protocol

the experience with rust-analyzer and rustrover/intellij-rust is a mess. most people find r-a flawless (or at least pretty good), but for some folks it crashes constantly for no discernable reason.

but rustrover and intellij-rust have historically had their own set of issues iirc

i think they weren't super great at proc macros? but i'm not 100% sure on that

also rustrover is going to be paid eventually :(

something about this, probably: https://learn.microsoft.com/en-us/windows/win32/shell/shell-exts

https://stackoverflow.com/questions/20449316/how-add-context-menu-item-to-windows-explorer-for-folders
The question itself is for folders, but the person links several things that they claim they tried and they're able to make it work for files. So I guess a mix of answers there (to understand the structure of related registry entries?) and the links provided could help?

There's also this https://learn.microsoft.com/en-us/windows/win32/shell/context-menu-handlers (linked in answer's comments) - shows a lot of stuff, including cascading menus

😓this hackathon sucks how I suppose to get axure credit as a learner

[harsh tundra]

What? Why are you replying to a random MS help link with Azure credits complaint?

[grave cove]

pretty sure the gh student pack gives you azure credits

[torpid slate]

I thought it was general chat first time

[harsh tundra]

That's what I wanted to say after that

[torpid slate]

😓its in general not for hackathon specially

Like I m in uni. They didn't give us mail

So I m unable to claim student pack

[harsh tundra]

It is. But why reply to my message where the only common thing is that it's Microsoft? Not even anything cloud related, quite opposite - it was a windows question...

[torpid slate]

😓idk why I replied

[grave cove]

your university doesn't give you an email?

[torpid slate]

No

[grave cove]

strange

well, at least in the US. maybe it's more common outside the U.S

[torpid slate]

Yes

Nahh... My uni sucks

[grave cove]

it is how it is

@torn python there's almost certainly going to be a third Dune movie. The first two were about the first book, and the third will be about the second book.
there are books after the second, but the second is the end of Paul's arc.

[paper sequoia]

Can you not use non-school email if you provide proof you are student? I can just remember incorrectly, been awhile since last checked

[dark epoch]

Using neovim, i've installed a language server using mason, but how do i actually run this? I'm using lack of text theme being applied to the files as an indicator that the language server isnt running, whereas my .lua files have text theme applied

[ancient minnow]

Any js nerds here?

I'm trying to do some hacking thing where I request a specific url using fetch

But the source im fetching from actually wants has "cors" mode enabled

Now if the url exists it shows up in my chrome devtools as status code 200, if it doesn't exist it shows up as status code 400

[lament cairn]

[ancient minnow]

Here comes the weird thing, because I'm forcing no-cors on this url, fetch always return a response with code 0

But the preflight throws an error: net::ERR_ABORTED 404 (Not Found) if the url doesn't exist

I have tried to catch this error

I have tried to even make an event listener on console.error

But there is no way for some reason to check whether the url exists or not

For more clarification

Like you see I do 2 requests

1 where the url exists

And one where it doesnt

It only throws the 404 once

Chrome devtools network tab

For both requests

[harsh tundra]

I think they can, it's just that school email is easier to verify for github and they tend to accept it faster

[paper sequoia]

Ye, makes sense. Now they have even started asking for credit card (or well any payment method to be added to account) + picture proof

[harsh tundra]

My uni would give you confirmation document in Polish or English that you're a student upon request, it should be the same in any school

[paper sequoia]

I don't remember when that started tho, not a new thing iirc but wasn't when I first registered

[paper sequoia]

We don't have such so... Re-newing that is pretty... Well, hard for me. There's tiny little spot in browser where it says the school name and your name, but I doubt it would be recognized, I feel it it would be somewhat automated system

[paper sequoia]

Oh, right, UNI. Ye those would have 100%

[harsh tundra]

Cc is usually needed for accounts on platforms themselves, it's common with any free stuff so people don't try to use it multiple times or abuse anything (cc info on file means they also have a name and a way to incur fines etc if needed)

[paper sequoia]

That makes sense, I been a bit hesitant about renewing as I don't own credit card, I don't want any random stuff happening on there, credit would likely be easier to refund if needed

I wonder when they started doing that

[harsh tundra]

Debit usually also works for those, you can even get virtual card that are pre-paid instead of connected to your account - so you just fill it with small amount and use it for online stuff

[paper sequoia]

In my case it was just school email and fill few fields on how you would use it and such, no other proof was required which was great and maybe crazy (this was like, what, 3 years ago now??)

[paper sequoia]

I been trying to look into those virtual cards, would very much like to use those for one-time purchases, like domain, hosting, stuff from the net in general. But I'm yet to find any proper information on them or where to acquire them from

[harsh tundra]

People in my uni group would do the gh pack several times - because as long as you had uni email, the process was basically automated (no other proof needed) and we had several aliases, like surname+first letter of name@domain, name+dot+surname@domain, studentnumber@domain...

[paper sequoia]

Ahh, makes sense that it was changed...

Btw, do you use any of those virtual cards?

Trying to find some info about them in general to see if I could use them

[lament cairn]

check your bank app

my bank lets me create temporary and virtual cards

ymmv

[paper sequoia]

Alrd did, they don't seem to offer such afaik

Kinda sucks 😔

One I have heard about is "privacy.com" but yet to figure out trustworthiness, don't want to give random card information to random websites in hopes of receiving usable virtual card

But also, US only so.. kinda have to pass

[spare oriole]

privacy.com is good, so is revolut

[pulsar heart]

sea chanties are awesome

[cursive salmon]

I've been using revolut and much better than my country's alternative

[civic pasture]

Loooool

[spare oriole]

What grade did you get in your DS thingie

[scarlet peak]

@grave cove apologies for the ping but i feel i have to ask these:

• should i use JS or TS?
• does TS work with JS frameworks?
• is there any stark difference between JS and TS besides strict types and typehints?

[grave cove]

• You can start with JS but you will most likely want to move to TS as soon as possible. It prevents a lot of mistakes
• Yes, the TS compiler transpiles TS to JS and removes the types. TS is pretty much a standard, and all modern, mainstream frameworks support TS
• You get a better ecosystem with TS, most of your frameworks and tools will support it

[scarlet peak]

ok ima start using TS then, thanks robin 👍

also do you know why this isnt working?

function digitize(n) {
    let L = [];
    for (const number in n) {
        L.push(number);
    };
    return L.reverse();
};```

[grave cove]

in doesn't do what you think it does:

Array indexes are just enumerable properties with integer names and are otherwise identical to general object properties. The for...in loop will traverse all integer keys before traversing other keys, and in strictly increasing order, making the behavior of for...in close to normal array iteration. However, the for...in loop will return all enumerable properties, including those with non–integer names and those that are inherited. Unlike for...of, for...in uses property enumeration instead of the array's iterator. In sparse arrays, for...of will visit the empty slots, but for...in will not.
Array iteration and for...in

Use a for...of loop instead:

const array1 = ['a', 'b', 'c'];

for (const element of array1) {
  console.log(element);
}

// Expected output: "a"
// Expected output: "b"
// Expected output: "c"

[scarlet peak]

tried it and got back: "n" is not iterable

because i'm passing it a number

but idk the equivalent of list() in js

[grave cove]

Are you trying to do a range thing?

(this is one of the reasons we use TS, btw, I can't know what type n is supposed to be)

[scarlet peak]

ah ok lemme switch to ts rq

what the fuck does this mean

OHHH

[grave cove]

array of what?

[scarlet peak]

wait im stupid its supposed to be a number returning an array

how do you define return types?

[grave cove]

function digitize(n: number): Array<number> {

}

I'm assuming you want to return an array of numbers

[scarlet peak]

yes

OHHH

yes

[grave cove]

i'm sure you can see many paralells

def digitize(n: int) -> list[int]:
  ...

[scarlet peak]

yeah

i was gonna do that

ok i see

but how do you convert between datatypes?

like list(), set() and int()

[grave cove]

depends on what the datatypes are

[scarlet peak]

ok, turning an integer to a list

in python

[grave cove]

how are you gonna do that

[scarlet peak]

i would do this

list(str(n))

[grave cove]

why

just do [str(n)]

[scarlet peak]

i need to return a list of numbers in reverse order

and ive already found out .reverse() does that

[grave cove]

in js you'd just do [n.toString()]

[thick ore]

that's not the same btw

[scarlet peak]

wait what

[thick ore]

["1", "2", "3"] vs ["123"]

[scarlet peak]

!e py n = 555 print([str(n)]

[royal lake]

@scarlet peak :x: Your 3.12 eval job has completed with return code 1.

001 |   File "/home/main.py", line 2
002 |     print([str(n)]
003 |          ^
004 | SyntaxError: '(' was never closed

[scarlet peak]

...

[grave cove]

yeah im assuming its just a single integer as a string

[scarlet peak]

!e ```py
n = 555
print([str(n)])

[royal lake]

@scarlet peak :white_check_mark: Your 3.12 eval job has completed with return code 0.

['555']

[scarlet peak]

💀

[scarlet peak]

"can be multiple" is what the question says

[grave cove]

the idiomatic way is to use Array.from

[scarlet peak]

what does idiomatic mean

[grave cove]

conventional/best practice

[scarlet peak]

ah ok

[scarlet peak]

how do i run TS files btw

[grave cove]

compile it to js first using the typescript compiler using tsc myfile.ts, which will create a myfile.js which is the compiled javascript, then just run it with node myfile.js

[scarlet peak]

found this:
https://marketplace.visualstudio.com/items?itemName=AlexDixon.vscode-typescript-repl

[grave cove]

ts-node is a tool that makes this easier by doing all of it for you, and automatically running your file when you save

[scarlet peak]

ohh thats what it was tryna run

how do i get ts node

[jaunty wraith]

there are also runtimes that run TS directly

[scarlet peak]

[Running] ts-node "c:\Users\user\OneDrive\Desktop\i hate programming\javascript (pain)\src\fuck.ts"
'ts-node' is not recognized as an internal or external command,
operable program or batch file.```

[grave cove]

https://www.npmjs.com/package/ts-node#installation

[scarlet peak]

just found it

[scarlet peak]

ok works fine thanks robin 👍

how do you convert between datatypes tho

[grave cove]

it depends on the datatypes

[scarlet peak]

string

wait

fuck

my brain is telling me to use map(int, rev_array) 💀

[grave cove]

rev_array.map(i => parseInt(i))

[scarlet peak]

basically i have this returned array js [ '3', '5', '2', '3', '1' ]

[grave cove]

i guess you can also just do rev_array.map(parseInt)

[scarlet peak]

oh sweet

ohh

its iter.map()

[grave cove]

yes

[scarlet peak]

instead of map(iter)

ok im getting it

and then int() is parseInt()

[grave cove]

yeah

[scarlet peak]

with float() being parseFloat() as well

ok im starting to see it

[scarlet peak]

its not working 😭

im getting fucking type errors now

[grave cove]

what's the error

[scarlet peak]

function digitize(n: number): Array<number> {
    let L = Array.from(n.toString());
    console.log(L);
    L.map(i => parseInt(i));
    return L
};```

ignore the file name

[grave cove]

it's not an in place operation

it returns a new list

[scarlet peak]

ah ok i see

shit stills makes no sense

[grave cove]

it doesn't let you reassign like that

at least, not without the same type

[scarlet peak]

"not without the same type"

explain

[grave cove]

essentially you can't define a variable to be of type number, then later re-assign it a string

you can reassign another number though

in your case, L is an Array<string>, so you can't do L = [1], because that's an Array<number>

[scarlet peak]

ah ok i see

[grave cove]

function chaining is idiomatic, here's the cleanest and most "best practice" version of the code:

function digitize(n: number): Array<number> {
    return Array.from(n.toString())
      .reverse()
      .map(i => parseInt(i));
}

console.log(digitize(123)); // [3, 2, 1]

[scarlet peak]

you can do that with methods?

[grave cove]

yes its very common

it works because JS/TS doesn't care about whitespaces

[scarlet peak]

ooh

nice

does python?

[grave cove]

not really

you have to wrap it in ()

so method chaining is not as idiomatic

[thick ore]

.map(parseInt)
