@PyGamer0 When I got the booster my arm didn't even really hurt, and I didn't feel sick or anything.

For the second shot I did get a tiny bit sick, but not too much

And for the first, same as the booster

So my immune system's either a lot better than y'all's or it's just too lazy to care, and I'm betting on the second if it's anything like I am

Adám

My experience was pretty much the same for all three shots (Pfeizer); pretty bad soreness building up over two days, then diminishing over two days.

My partner had the same experience with the first two, but then had Moderna as booster, losing consciousness the day after the shot. Spent some time in the ER/A&E.

user

Whoa

PyGamer0

wha

user

My arm just hurt for a couple days for all the shots, I feel lucky now

PyGamer0

14:37

ok now my hand (the portion i got my vaccine) is paining

@user i have my exams in a couple of days, and i write with my left hand

mathcat

good luck then

PyGamer0

truly the worst time i could have gotten a vaccine lmao

user

That sucks

Why didn't you get it on the other arm?

PyGamer0

lets see how long it pains for

@user \_○_○_/

Redwolf Programs

Seriously...I just deleted a college spam email, and I look back at my inbox and I have another one

user

14:39

Careful there, don't raise your left arm too high or it'll hurt :P

PyGamer0

i didnt know i could do that :p

Redwolf Programs

I don't know how Montana State hasn't gotten the memo

PyGamer0

@user ouch you are right

user

@RedwolfPrograms If it's any consolation, it's gotten better for me now (I'm a senior)

Redwolf Programs

That's good

user

14:40

I assume they target juniors more

Or maybe Gmail's just gotten better at classifying those emails as spam :P

Redwolf Programs

And I'm a sophomore, so it's probably going to get pretty bad next year

user

:|

Expect to get emails not only from colleges you've literally never shown interest in, but also from colleges whom you've applied and been accepted to

PyGamer0

:/ :| :\

:-

user

Prolog fan?

PyGamer0

so :/ :| :\ :-

@user i never used it

idk hello world

user

14:42

Just mentioning it because prolog uses f(A) :- body. iirc

@PyGamer0 I think it's as simple as ?- writeln("Hello world"). Don't quote me on that though

PyGamer0

which paradigm is prolog

Redwolf Programs

Logic

user

Logic? Declarative?

Ninja'd

PyGamer0

Logic?

Redwolf Programs

5th generation

PyGamer0

14:43

€_£

user

It's quite interesting, you solve predicates

PyGamer0

£_€

yeah ill stick with APL for now

user

So if you want to find the greater of two numbers, you wouldn't write a function, you'd do f(A, B, A) :- A > B. or something like that

@PyGamer0 You can learn both APL and Prolog

It's just a cool new paradigm to see

PyGamer0

no thanks

user

:(

PyGamer0

14:47

f =: 1 % 2 NB. Gives 0.5 :)

user

@PyGamer0 Just see this and feel the awesomeness of unification or whatever it is Prolog uses

pxeger

today I unaccepted an answer, and it keeps confusing me that my rep gained is +178 (or whatever)

user

I never understood why accepting an answer gave you rep anyway

pxeger

Probably just to encourage newbies to do it, because otherwise there's absolutely no incentive

user

I assume it's incentive for not leaving a question with an unaccepted answer, but if an answer really helps you, you'd do it anyway

PyGamer0

14:50

@user ⍎⌽⍕⌈*○≡⍬

Redwolf Programs

@user You'd be surprised

user

Then you have people (like me after first joining SO :( ) who accept answers just to get rep

@PyGamer0 Is that Extended?

PyGamer0

@user probably no

no

user

Oh it's just this font being weird lol

Ginger Industries

15:04

hello

Redwolf Programs

Hi!

mathcat

@GingerIndustries the cat's looking really disappointed

Ginger Industries

one sec, I updated the picture

alr

just cropped it slightly

@RedwolfPrograms I probably should've clarified, when I said I would also do that I was not referring to saying "cool, nobody asked", I was referring to editing a message after sending it for comedic effect

pxeger

TIL you can phone (!) replit to run code. hotline.replit.com

Ginger Industries

what

Redwolf Programs

15:11

Reminds me of the flag-down-and-ice-cream-truck-and-hand-them-a-floppy-disk thing from xkcd :p

:p]? New emoticon?

Ginger Industries

this must be an april fools joke

Razetime

it definitely has to be

Ginger Industries

can somone try this

we must know

Redwolf Programs

I wish I could, I'm in school :(

Razetime

it's gotta be a rickroll

i cannot overseas call rn

Redwolf Programs

15:12

Maybe I could tell the teacher it's an emergency

Ginger Industries

hmmm

also Dancing Emoji Generator is functional

I am very proud of my accomplishment :)

one sec, I'm gonna add a "cursed mode" that removes the charset tag

Redwolf Programs

Ooh +1

pxeger

@GingerIndustries it does seem to actually work

Ginger Industries

+1 what? cookies?

pxeger

although I tried running 7*2 in Python, and it said "we've run into an internal error"

Redwolf Programs

15:14

Brownie points

Ginger Industries

@pxeger that's the best compliment I've gotten today

oh you were referring to the hotline

Redwolf Programs

They were talkimg about the replit thing not your emoji generator :p

ninja'd

Ginger Industries

I thought you meant the generator

pxeger

oh

Ginger Industries

;-;

Redwolf Programs

15:15

Is :]p a :] with a weird beard, or a :p with a weird moustache? Discuss.

Ginger Industries

hmmmm

Redwolf Programs

This will be 50% of your final grade.

Ginger Industries

hmmmm

Wezl - a cautionary tale

good thing I gave myself extra credit on the other part of the quiz

Ginger Industries

It's an alien with two mouths

I need an emoji to test Cursed Mode on

@RedwolfPrograms out of those options it looks more like the moustache, but I think the ] should be a nose

beautiful

mathcat

how to use it?

Ginger Industries

copy into web browser

pxeger

15:20

just paste it into the URL bar

Redwolf Programs

Without cursed mode and with a really high frame speed, it looks like his arm is a machine gun

Ginger Industries

also Cursed Mode appears to be stuck on

one sec

Redwolf Programs

(I was going more for a punch type thing, but it looks more like recoil since I put the in-between frame in the wrong spot)

mathcat

it's outputing this: (à² _â– )âŒ

Ginger Industries

fixed it

Redwolf Programs

15:21

@mathcat It's cursed mode, add <meta charset=utf-8> for non-cursed

Ginger Industries

reload for non-cursed to work

I just had it checking value instead of checked

mathcat

was the space intentional?

Ginger Industries

@mathcat eh?

@RedwolfPrograms pure art

Redwolf Programs

Somebody who's sleep deprived and doesn't know the answer to your question:

Ginger Industries

tbh these should be exportable as GIFs

anyone know how to use <canvas>?

Redwolf Programs

I do

Ginger Industries

my saviour

Redwolf Programs

And maybe there should be some sort of condensed base64 representation that's shorter than the full links

So you can just paste that into your generator

Ginger Industries

15:26

I did think that

one sec, lemme make the b64 thing

can you try the gif part? I am not large brain enough for that

Redwolf Programs

I'm not actually sure how to do a gif with canvas, PNGs are easy, but I'll have to do a google

Ginger Industries

nice

thx

Ginger Industries

...

mathcat

you're atting me

2

Ginger Industries

15:29

I'm also going to add text formatting

because yes

Redwolf Programs

Saving as webm seems possible, but gifs aren't part of the MediaRecorder API :/

Ginger Industries

webm then i guess

;-;

Redwolf Programs

Maybe permalinks would be a better option

Since webms wouldn't be onebox-able anyway

Ginger Industries

I'm working on font formatting first, then permalinks

Redwolf Programs

Perhaps JSON+UTF-8+base64 would work

Ginger Industries

15:31

what

so i'm going to do it like this:

First 4 characters: Font ID and size
Next 2 characters: Number of frames
Everything after that: Frame data

tbh your idea is better tho

i'm going to appropriate it

Redwolf Programs

Use a TextEncoder for UTF-8

pxeger

doesn't valid JSON technically need to escape unicode characters, so it's ASCII only? (even though JS's JSON.stringify doesn't do that)

Ginger Industries

eh, we can just store each character as a Unicode codepoint

Redwolf Programs

btoa([...new TextEncoder().encode(" ┐ ._.┎")].map(c => String.fromCharCode(c)))

Ginger Industries

Like that

Redwolf Programs

15:35

This will encode arbitrary text as base64

Lemme make a decoder

Wait, you need a .join("")

btoa([...new TextEncoder().encode(" ┐ ._.┎")].map(c => String.fromCharCode(c)).join(""))

Decoder:

new TextDecoder().decode(new Uint8Array([...atob('IOKUkCAuXy7ilI4=')].map(c => c.charCodeAt())))

Ginger Industries

got it

Redwolf Programs

So probably just encode the frames, font, and timing as an object and JSON.stringify it, then use that encoder

Replace + with - and / with _ for web safe base64

Ginger Industries

formatting appears to work

Redwolf Programs

And you can drop the =s entirely

Ginger Industries

so the idea would be to just have the url be like https://<site>/show#<b64>?

Redwolf Programs

15:43

Yep

I'd use a ? though, personally

Ginger Industries

@RedwolfPrograms what's the difference?

Redwolf Programs

I don't know too much about the technical differences, but ? seems more fitting

pxeger

if you use # for that, then you can't use # for linking to specific parts of the page (which is what # is supposed to be for, and does by default), which you might want in future

Ginger Industries

with ?, you have to specify the name (i.e. /show/?b64=<b64>) but with # you can just use it (i.e. /show/#<b64>)

@pxeger this page will never have anything that isn't the animation, so in this case it doesn't matter

Redwolf Programs

Fair enough, I guess

mathcat

@Wezl-acautionarytale NOO

Wezl - a cautionary tale

15:51

you don't like my animation?

Ginger Industries

@Wezl-acautionarytale :/

mathcat

I er like it

Ginger Industries

really

mathcat

of course

Redwolf Programs

You beat me to it, I was going to do a rickroll :p

Ginger Industries

15:51

REALLY

ಠ_ಠ

Redwolf Programs

16:06

How's the permalinking going?

Ginger Industries

@RedwolfPrograms I've gotten encoding done, working on decoding and display

Redwolf Programs

Nice. Permalinks should make things a lot easier.

Ginger Industries

@RedwolfPrograms ???

Redwolf Programs

You should also probably make it so people can't inject JS into the emoji

Ginger Industries

I tried

Redwolf Programs

16:14

JSON.stringify the .value first

That should give you a properly escaped string

hyper-neutrino

why is mee6 (the discord moderation bot) making an nft

wth

Redwolf Programs

Is there a data structure similar to a list where inserting items is O(log n) or better, as well as finding the index of an item?

Linked lists or binary search could give me either of those, but I don't see an easy way to combine them to get both

hyper-neutrino

binary search trees are log N insertion, removal, and search IIRC

Redwolf Programs

Oh cool, thanks!

hyper-neutrino

although they're sorted so not really like a list, but you also can't binary search in a list anyway

Redwolf Programs

16:21

Yeah, I don't need to handle duplicates/ordering items, I just need a fast way to check if something's already in the list/tree

hyper-neutrino

why not a hashset then

Redwolf Programs

Because I know literally nothing about data structures :p

Just stumbled across the wikipedia page for those and they seem like they'd work

hyper-neutrino

hashsets give you amortized O(1) for insertion, membership check, and removal

Ginger Industries

it almost works
https://dancing-emoji.gingerindustries.repl.co/show.html#eyJtZXRhIjp7ImZvbnQiOiJzZXJpZiIsImZvbnRzaXplIjoiMTYiLCJjdXJzZWQiOmZhbHNlLCJzcGVlZCI6IjUwMCJ9LCJmcmFtZXMiOlsiKCVFMCVCMiVBMF8lRTIlOTYlQTApJUUyJThDJTkwIiwiKCVFMCVCMiVBMF8lRTIlOTYlQTApLSVFMiU4QyU5MCIsIiglRTAlQjIlQTBfJUUyJTk2JUEwKS0tJUUyJThDJTkwIl19

pxeger

(still O(n) worst-case though)

Redwolf Programs

16:25

[term] redirects here. For the South Park episode, see [page]. For the IRC command, see [page]

hyper-neutrino

yeah. you'd have to have some terrible luck or intentionally designed data to get that tho

Redwolf Programs

@RedwolfPrograms A data structure, south park episode, and IRC command....quite the variety of things :p

Ginger Industries

the Holy Trinity

pxeger

@hyper-neutrino or just a poorly designed hash function

@RedwolfPrograms "rehash", for those wondering

hyper-neutrino

@pxeger true

would you get that from bad probing or does that not really matter so much if your hash function is half decent

pxeger

16:28

I don't think bad probing would cause it

Bad probing wouldn't change the complexity, but is slower for other reasons like because of CPU cache locality

If you design the hashset's memory management poorly, you could get slow insertion and removal more than almost never

And if you overfill it / use too few buckets you could have lots of hash collisions

mathcat

I made a user-friendly text animator!

my first data url

pxeger

I'm not clicking a data URI which is base64 encoded for obvious obfuscation reasons

oh look, a rickroll, whoever could have guessed

setTimeout(function( ) { clearInterval(id); window.location.replace("https://www.youtube.com/watch?v=dQw4w9WgXcQ");}, list.length*2000);

Wezl - a cautionary tale

@mathcat very user-friendly

mathcat

@pxeger actually I did it because it didn't work otherwise

Wezl - a cautionary tale

@pxeger sssssssssh we don't need to ruin people's happiness and joy and fun

wizzwizz4

16:38

@mathcat You could've removed the spaces.

mathcat

then it would've worked?

Wezl - a cautionary tale

language with string subtraction

pxeger

I've occasionally wished Python had list negation, so that -[1, 2] * -2 == [1, 2] * 2

mathcat

I've often wished python would let me subtract from string digits.

It makes things a lot easier

Fmbalbuena

@pxeger use for loops
