Q: Bijection between \$ \mathbb N \$ and at-most-\$n\$-ary trees

Background Related: a golflang theory I posted in TNB a while ago At-most-\$n\$-ary trees are rooted trees where each internal node has between 1 and \$n\$ children (inclusive). Two trees are considered identical only if the shapes exactly match without re-ordering each node's children. In other ...

I made a script to generate human-rememberable names for stuff. Considering some of them as usernames:

fizz fops
ring atop
rink woof
jays swad
buff firs
wigs sink
bind wind
boon gain
gyro cork

Hi! This is rink woof. Make sure a bind wind doesn't boon gain your buff firs, you can try a gyro cork to fizz fop them, but make sure jays swad is ring atop.

Never mind this actually just sounds like it's a meme from ten years in the future that I just don't get yet :p

exedraj

02:04

buff firs sounds like someone who would commit tax evasion

Redwolf Programs

jays swad sounds like buff firs' cool friend

and gyro cork sounds like it'd be some sort of gymnastic move

I am considering changing my username to rink woof though

exedraj

wigs sink is that one guy with an elevated sense of justice, and would condemn buff firs hatred of the IRS

Redwolf Programs

fizz fops sounds like they'd work at a bowling alley that has ties with the mafia

exedraj

boon gain sounds like the person who would make moonshine during prohibition.

Dude coinheringaahing

@RedwolfPrograms Imo "fizz fops" is a different version of "fizz buzz", designed so that Vyxal isn't hyper-specialised for it :P

CMC: Generalized FizzBuzz; take a list of (you can assume coprime) numbers, and another list of equal length with the corresponding names. Not necessarily two numbers.

Ooh, is this not on main?

exedraj

@RedwolfPrograms Vyxal j, 8 bytes: ₁ƛ?Ḋ?*∑∴

Redwolf Programs

Hang on, from a few minutes of dupe searching this might actually not be a dupe

Ignore the CMC, this is going on main

exedraj

@Dudecoinheringaahing do you ever use your dog for making HTTP requests?

more specifically, PATCH requests?

Dude coinheringaahing

@exedraj From time to time, but he gets easily distracted :P

@RedwolfPrograms I'm pretty sure this is a dupe, hang on

It's not coming up in any of my searches, but I'm sure we've had something like that recently. Was it a CMC?

May 6 at 14:05, by caird coinheringaahing

CMC: Given a unique list of pairs (natural number, non-empty string), output FizzBuzz from 1 to 100, but the divisible tests and the corresponding strings are defined by the input. For example, the standard FizzBuzz would be [(3, "Fizz"), (5, "Buzz")]. The output for [(2, "A"), (3, "B"), (5, "C"), (7, "D"), (11, "E")] would be:

Yeah, I came to the conclusion that it'd just be a dupe of Fizz Buzz imo

Redwolf Programs

02:32

It seems interesting and not very much like a dupe, to me

Would you be fine with me posting it? I think it could be interesting (and I'm halfway through writing it :p)

Dude coinheringaahing

Yeah, go ahead. I'll FGITW my answer to that CMC :P

Redwolf Programs

It'll be maybe a half hour before I post it, I have to go do some stuff first :p

Bubbler

Maybe also take the last number (instead of 100)?

Dude coinheringaahing

@RedwolfPrograms I generally consider the "meat" of the two challenges when I dupe-close, and to me, the meat of these two are "over each element in a range, select strings based on divisibility tests"

Although they're distinct enough that I'd prefer to cast a regular VTC if I could, rather than hammer

Bubbler

I'm pretty sure there are many answers that hardcode 15 as well as 3 and 5, which is impossible in the generalized version

Dude coinheringaahing

02:51

@Bubbler I don't know why, but that provokes a somewhat visceral reaction for me :/

Fizzbuzz methods that separately handle 15 are already bad enough, but then you make it code golf and it's 1000 times worse

user

Eh, it’s fine if you have a constant for each id the three outputs

Redwolf Programs

@Bubbler I was planning on doing that, but with the additional option of infinite output

Sort of like sequence rules

Dude coinheringaahing

I'd suggest not allowing nth term

Unrelated String

^

Redwolf Programs

I'm not, no

Hence sort of like :p

Unrelated String

02:58

yeah

Dude coinheringaahing

Although, I'd imagine that most First N ones would just iterate calculating the nth term method over each N

Razetime

i suggest not allowing answers

Redwolf Programs

@Dudecoinheringaahing So would the infinite ones though, probably

Dude coinheringaahing

People have to answer in comments :P

user

@Razetime very wize

Dude coinheringaahing

02:59

@RedwolfPrograms Yeah. I can't think of a non-nth term fizzbuzz approach tbh

user

Even better, don’t post the question sp there’s no comments or edits 😛

Bubbler

@Dudecoinheringaahing Not that I advocate those answers anyway, but do note that some langs don't have enough storage to store the boolean variable, etc

Redwolf Programs

@Dudecoinheringaahing I can, iterate over every xth answer (where x is each input) and append the string, then fill in empty ones

Dude coinheringaahing

Especially given as there's no way of telling what the next element should be, given an element of the sequence

@RedwolfPrograms That's just a fancy way of iterating over each element :P

Redwolf Programs

I mean it's not like there's a crazy amount of different possiblities, but that's true of the majority of challenges

Dude coinheringaahing

03:03

Yeah, it's not a criticism

It does have me thinking about another challenge tho: given an element of the Fizzbuzz sequence, output the next element

Obviously repeated elements would need to be handled, probably going by their first occurenece

Redwolf Programs

Sounds pretty boring, right? Fizz is 4, Buzz is 6, FizzBuzz is 16, and the rest are just n + 1?

exedraj

That's why it should be 3 elements

@RedwolfPrograms not necessarily. What about if n + 1 is a special number?

Redwolf Programs

Hmm, true. fizzbuzz(n + 1) then :p

And Buzz is Fizz

Dude coinheringaahing

Yeah, I'm thinking of ways to make it slightly more interesting, but the base is there :P

exedraj

Q: Generalized FizzBuzz

Task FizzBuzz, but instead of 3 and 5, you'll take the numbers and corresponding strings as input. You can assume all inputted numbers are coprime (and \$\ge 2\$). You'll receive one or more numbers, and a string to print with each of them. The normal FizzBuzz would be something like [[3, "Fizz"]...

V6.0 (🇹🇼) flag for Taiwan

user

Heh

Redwolf Programs

Some of these are just territories though, like the svalbard one

Dude coinheringaahing

@RedwolfPrograms That might be the most countries recognised by any body. In fact, I'm not sure there are even that many countries with at least some form of recognition

V6.0 (🇸🇯) flag for Svalbard & Jan Mayen

Who is jan and why does he have his own flag

Redwolf Programs

jan Misali?

Redwolf Programs

It's fun to read the emoji list as if it's a story. "place of worship wrench and hammer" is one of the more worrying ones, but it's no match for "weary cat face helicopter"

exedraj

@RedwolfPrograms you happy now?

Redwolf Programs

wait so uh...# V7.0 (🖕) REVERSED HAND WITH MIDDLE FINGER EXTENDED

unicode?

are you okay buddy?

somewhere in some stuffy unicode meeting some guy was like "we should add a middle finger" and everyone was like "yeah, definitely" :p

user

🤬

@RedwolfPrograms they have nothing better to do

I bet most unicode meetings are like “aight people what new wack chars can we add to screw with devs and users”

Redwolf Programs

Also TIL the copyright symbol © is technically an emoji

snowman without snow = man

Unicode canonically refers to the person who slides down chimneys as Father Christmas

How to build a snowman:

1. Find a man

2. Find snow

today I stumbled across a markdown variant I once made: github.com/Lyxal/Documentationizer

PyGamer0

@exedraj nice

exedraj

I also found the terrible spam bot I wrote: github.com/Lyxal/SpamBot

excellently written in python

it was used for a few laughs in class once

because my friends were signing each other up for spammy websites

so I decided to trump them all with code

while they were busy inefficiently visiting sites, I wrote something to automatically send emails from my account

Bubbler

That... might have violated ToS of the email service

exedraj

it was horribly inefficient, so I don't think it would have mattered

also, it was all outlook accounts

so as if Microsoft would care if a 16 year old wrote a spam bot that used multithreading incorrectly and used it once

I added an email verification code and everything

and of course, it used my crappy tkinter wrapper

emanresu A

Why tkinter

exedraj

06:07

because python

emanresu A

tkinter for graphic stuff

exedraj

yeah

it had a GUI

*has

but it didn't work

because 2FA

Adám

Isn't it called a gaffe?

exedraj

@Adám ah yes, I do love having 0 texts of unlimited with my mobile plan

But that is a bit stingy only giving GB of 500MB.

They could have at least given a few more GB of 500MB

but that's kinda made up for by the 29 minutes of unlimited

my current provider only gives me pi minutes of unlimited per km per hour

;p

PyGamer0

me participating in LoTM

look at last 2 lines for an easter egg (or a 🍪)

Adám

@exedraj It is actually the usage that's shown. So I've used GB of my 500 MB allowance etc.

exedraj

08:16

@Adám you've...used GB of MB?

@Bubbler Yep, and thanks for the reference implementation.

Unlimited calls on the condition that they're exactly 29 mins long

I love how the link of this is just obfuscate-my

pxeger

@Adám Adám, are you versed in the art of complaining at call center representatives and threatening to switch providers to get a better deal on your mobile contract?

I pay £6.50 a month for 8GB + unlimited texts/minutes (SIM-only, 12-month contract, on Three) after half an hour on the phone

emanresu A

Imagine using pounds

pxeger

CMQ: what are there more of in the world: catseyes or cats' eyes?

emanresu A

1.2 billion of the latter

exedraj

@pxeger noob

I only pay £2.65 for 20GB a month with unlimited talk and text

pxeger

do you have free roaming in most developed countries?

exedraj

Yesnt. But it's not like I ever leave Australia

and do you have to deal with Telstra (shivers)?

No

No I don't

How's lockdown going?

pxeger

@emanresuA yes

Ok

exedraj

TIL I was in an area just 15 minutes after someone with covid was there

@pxeger kogan mobile ftw.

But telstra isn't that bad though

Final feedback?

At school today we were discussing lowering the voting age

and someone said

"Well in Among Us you can vote at any age..."

exedraj

@pxeger my uncle got 150GB, unlimited talk/text for free for a year with them after they screwed up changing his number from post to prepaid

And by screwed up, I mean leaving him without phone access for ~3 days

So maybe they are a little bad

emanresu A

Ouch

pxeger

@emanresuA I'd like the voting age to be lowered for people like me at age 16, but most of my friends at that age were idiots

— every 16-year old ever

exedraj

@emanresuA I mean they do got a point. Anyone should be able to vote out sussy prime ministers

pxeger

when the scomo is sus 😳😳

@exedraj then again, that ain't necessary when they do that themselves

pxeger

@emanresuA which country is this?

emanresu A

NZ

Adám

@pxeger I've done so for broadband, but the image is at the end of the month, and the "GB" glitch is due to my usage being exactly 0, so as you can see, I hardly need to negotiate anything better.

pxeger

oh lol

emanresu A

Good job

Adám

09:28

I'd be good to pay less for even fewer GBs, minutes, and texts, but I can hardly save more than £6 per month.

pxeger

how do you not at least accidentally use some mobile data though?

or is it not exactly 0 but almost 0?

Adám

1. I barely ever leave home, so I have WiFi all the time
2. I suspect my phone doesn't know how to use data.

pxeger

oh 2 makes more sense

I also barely leave my house but sometimes my phone decides the WiFi has died and uses data

Adám

My wife's phone does know how to use data, but I think she keeps data off unless she needs it. And she's only left home once in the last 1½ years; to get her vaccine.

emanresu A

My relationship with my phone: Leave it to die until I need it.

pxeger

09:32

@emanresuA that's my brother's attitude as well and it annoys the living daylights out of me lol

I can never contact him

emanresu A

@pxeger You can contact me... 5% of the time.

Adám

I have my phone with me most of the time, but there's no temptation to become engrossed in it, because it is one of these:

emanresu A

Can it do anything aside from texting and calling people?

Adám

Snake.

pxeger

it can tell the time and date judging by the picture lol

Adám

09:34

Flashlight.

Calendar.

Calculator.

emanresu A

@Adám It's actually quite valuable then

@Adám More useful tho

Adám

Alarm clock.

It even has radio!

emanresu A

Hm

Adám

The only thing I really miss from my previous phones is T9. I have no clue why they got rid of that.

emanresu A

eval([...document.getElementById('sussytable').childNodes[2].childNodes].slice(1).map(x=>+x.childNodes[7].childNodes[0].nodeValue.replace(/,/g,'')).filter(isFinite).join`+`)

This is what I must do to answer pxeger

Adám

09:37

Oh, and sometimes, the font's mediocre Unicode support gets annoying, like when people text me in Hebrew, and it is like "⎕⎕⎕⎕ ⎕⎕⎕ ⎕⎕⎕⎕⎕ ⎕⎕⎕!"

pxeger

@emanresuA what was the question?

emanresu A

Your catseye thing

There are 22547319 kilometres of paved road in the world

pxeger

ah I see

emanresu A

But I have no idea how many catseyes that is

so kinda pointless

pxeger

and not much of the world's road has catseyes on it

emanresu A

09:40

Why, traffic designers. Just why.

Adám

Seems sensible enough.

emanresu A

i.sstatic.net/DB19T.jpg x

Compared to this, yes

Adám

@emanresuA Severe topological constraints there. They didn't have much wiggle room.

Which country is this? They drive on the left.

emanresu A

All from this list

pxeger

@Adám they might just have backwards arrows...!

emanresu A

09:43

img.odometer.com/filter:scale/quill/9/f/3/d/b/7/… is worse

Adám

If you follow the various paths cars could take, it is quite reasonable.

emanresu A

img.odometer.com/filter:scale/quill/0/b/e/4/a/0/… question mark

Ok, img.odometer.com/filter:scale/quill/d/7/5/b/2/2/… takes the cake.

pxeger

none of these look too confusing if you were in a car driving on them

Adám

Exactly.

I think the UK roundabouts of roundabouts are much worse.

emanresu A

You really have to question img.odometer.com/filter:scale/quill/5/7/4/9/b/3/… though

Adám

09:47

That's either intended as art (!) or in preparation for more roads connecting.

emanresu A

Over a river?

newstalkzb.co.nz/media/22939233/… is sus

And I don't think img.odometer.com/filter:scale/quill/3/d/2/9/1/2/… can even be called an intersection.
