You're to have some drink. Each bottle of drink has \$n\$ extra parts than the drink(bottle, etc.) \$P_1, P_2, ..., P_n\$. You can buy a bottle of drink using 1 dollar, \$a_1 P_1\$s, \$a_2 P_2\$s, ..., or \$a_n P_n\$s. When buying a bottle of drink, you also get one of each of \$P_1, P_2, ..., P_...

hey there @bobble! :D

@RedwolfPrograms playing mc in class? smh such an irresponsible student

i would never be an irresponsible student

Redwolf Programs

I mean school's basically over :p

wat

Redwolf Programs

There's maybe two weeks left in school here

3:27 PM

hey there, was going to lurk as first period is boring

@RedwolfPrograms oh. when does the school year start for you guys?

Redwolf Programs

August

ah

forgot that american school year is like a whole month-ish earlier than canada's lol

@bobble ah, well, apologies if you didn't want to talk, i'll let you lurk :p

I'm in 'murica and my school year does not end in two weeks, because my school is weird and ends in mid-June

huh, interesting

3:30 PM

@bobble That's weird? Mine ends in June too

our school year always starts the day after labor day

Redwolf Programs

May 27 here

@hyper-neutrino So does ours

Wish school ended earlier here

so our school year usually goes to around june 22-26 or something like that

@RedwolfPrograms When do y'all take APs then?

Redwolf Programs

3:31 PM

Same time as y'all I'd imagine

oh I just assume my school is weird in all ways because we're weird in a lot of ways

Redwolf Programs

I've already taken one, and my CS one is Monday

@user A lot of ours happen in early June/late May

Redwolf Programs

Oh, maybe the second wave of them then

@RedwolfPrograms Good luck! Mine's on Tuesday

Redwolf Programs

3:32 PM

Is it Computer Science A, I'm guessing?

Yeah

plebs. I'm taking 5 APs this year

I actually took it last year but got a 3 on it, so I'm taking it again :(

Redwolf Programs

I'm in the one before that one, since I'm only in 9th grade

i only took one AP total (calc BC), lmao

@bobble 5?? wow :o well good luck with all of them :P which ones are you talking?

3:33 PM

@hyper-neutrino Calc BC sucks, it's all you need to take

i think like 44% of people who took it that year got a 5

@hyper-neutrino Phys 1, Phys 2, Lit, Gov, Econ

Redwolf Programs

Over all four years of HS I'm planning on taking something like 18 AP tests lol

darn, I'm going to have taken less than you then. (I will have taken 11 tests total)

~~imagine not being in grade 2 and stealing an adult's account~~

Redwolf Programs

3:36 PM

AP Human Geo is the only one I've taken so far

@Wzl @hyper-neutrino Time to delete Wzl's account

._.

@hyper-neutrino Wait, Calc's that hard?

Redwolf Programs

Hard?

@user wait that counts as hard?

Redwolf Programs

3:38 PM

44% getting a 5 is ridiulously high

@user what no that would hurt my host adult :::)

i'd say 44% of people getting a 5 counts as really ez

Redwolf Programs

It's 10% for most AP tests

Oh no

apstudents.collegeboard.org/about-ap-scores/score-distributions

Redwolf Programs

3:39 PM

I have that bookmarked lol

0.6% of last year's AP 2-D Art and Design students got a 5????

not that I'm taking that test but what

Ok, at least there's like a 40% chance of getting a 4 or 5

@bobble 2D art is a lot harder than 1D art :P

highest was chinese language+culture at 55.4%, lmao

Huh, I thought languages would be one of the hardest

Redwolf Programs

Y'all have it backwards

0.6% is a 1

5 is on the left

3:41 PM

oh I do

oh. F

that's... a really unintuitive way to arrange it

anyway, i was looking at it correctly it seems :p so yeah chinese had the highest ratio of 5s

are older score distributions available? i took my AP calc BC in grade 11 so it would've been from 2019

Redwolf Programs

You can find them online yeah

totalregistration.net/AP-Exam-Registration-Service/…

secure-media.collegeboard.org/digitalServices/pdf/research/2019/…

3:43 PM

ah. thanks

so yeah, 43.0%, lol

Redwolf Programs

Looks like AP Seminar is the hardest to get a 5 on

I'm taking that next year :|

4:08 PM

Sorry to self-promote, but the PPL website is now available, so my language could find use on codegolf, even though it's very, well, primitive. Here it is. I also created a PPL room.

4:21 PM

congrats on making a language

is that sarcastic or not? sounds like sarcasm

or maybe i'm misinterpreting it

Since I'm here, is it possible to entice anyone to help dig through Lit's Unanswereds? :) Nice thing about having >1000 Unanswered questions, there's always a few that you can do something about

unfortunately, don't think there's much help I can offer for anything relating to literature :'( i'll take a look if i have time :P

If you want to try some easier ones, low-voted [meaning] questions are usually just reading comprehension, or recognizing idioms/allusions

4:37 PM

oh alright, I'll see if I can figure out any. don't read as much as i probably should but hopefully my reading comprehension is at least good enough though lol

one would hope a High and Powerful mod would have reading comprehension

5:05 PM

wew, just wrote a 487-byte jelly solution to the song chaining challenge

Redwolf Programs

5:14 PM

is listening to music while doing stuff a normal thing?

Yeah.

caird coinheringaahing

I think I spend 90% of my life listening to music

Redwolf Programs

huh, til

caird coinheringaahing

It's difficult, but I can just about squeeze everything else into that 10% :P

wow that's interesting hmmm

5:16 PM

i listen to music quite regularly when i work and i honestly don't know if it makes my productivity better or worse

I like to listen to music when I cook.

@WheatWizard piano sound effects

@WheatWizard what do you like to cook?

I don't think music makes me more productive, but I really don't care. I like it.

caird coinheringaahing

@WheatWizard Same. Idk why, but it often helps with the rhythm of cooking for me

on one hand it might be distracting but on the other hand it reduces environmental noise (which lets me keep my window open more) and it helps a bit with my thoughts wandering probably

5:17 PM

@Wzl The food I eat? I cook everything I eat.

necessary follow up question: what do you like to eat?

~~the food he cooks~~

2

I eat a lot of beans.

@hyper-neutrino >:|

@Wzl I eat <s>food</s>

5:19 PM

I'm vegan, so beans are like my food.

caird coinheringaahing

@ophact ---strikethrough--- ~~strikethrough~~

mmm beans

Tonight I had rice pilaf.

I guess I eat a lot of fruit too. But I don't cook that most the time.

Redwolf Programs

> I cook everything I eat.

Lies!

:p

caird coinheringaahing

Pretty sure you don't eat fruit, you absorb it. Right, fellow humans?

5:21 PM

I assimilate it.

caird coinheringaahing

Resistance is fruitile

@cairdcoinheringaahing right but us weasels just stick our noses in and inhale

@cairdcoinheringaahing there needs to be some kind of FAQ on this, it gets asked so often

hey, we hit 58 million messages network-wide

(just noticed from the reply IDs)

caird coinheringaahing

@pxeger chat faq, formatting

5:25 PM

userscript for easy chat formatting time?

caird coinheringaahing

I have a chat shortcut for it tho (I type /strike and it inserts the message for me

This is so Java:

Q: Why am I getting AbstractDynamicObject$CustomMessageMissingMethodException error?

I have just started a new project and am trying to connect to Firebase.

When I re...

android firebase gradle

Redwolf Programs

It's because they forgot to use a factory

the main issue is probably that people don't read the faq cuz it's a tiny link in the corner and ---strikethrough--- ~~strikethrough~~ is neither conventional nor consistent with SE's main sites

41 upvotes in 2 days? huh

caird coinheringaahing

Check the answer, 101 and accepted

5:27 PM

I guess every single person who updated to that version ran into that bug and swiftly googled it

ah that would make sense

TIL you can un-upvote if you edit a question :)

yes, though if i notice someone doing trivial edits to change voting i will warn them

caird coinheringaahing

You can only un-upvote if a post gets edited :P

but yes, you are able to do that lol

i wonder, can you retag to hammer? i don't think so

caird coinheringaahing

5:30 PM

I don't think so

But you can retag to get a hammer

as in retag to gain score in that tag?

caird coinheringaahing

Yes

ah

caird coinheringaahing

If you have an answer at +1000, you can edit a tag into the question and immediately get a hammer (assuming you have some answers in the tag as well)

i also wonder then, can A edit for B to hammer... this would be something great to try on sandbox.SE if we had one :P

5:32 PM

@cairdcoinheringaahing No you can't.

There is a mechanism against that.

caird coinheringaahing

@hyper-neutrino Yes, other users can edit tags so that you can hammer

@WheatWizard Oh, did they change it? I remember there being a MM post about bobnice being able to do that on the "parsing HTML with regex" question

I think the rule is pretty old.

@cairdcoinheringaahing what do you mean by hammer?

caird coinheringaahing

@pxeger Users with gold tag badges can "hammer" a question tagged with one as a duplicate

oh I see

caird coinheringaahing

5:34 PM

For example, I can unilaterally close any code-golf question as a duplicate

Additionally, mods can hammer any question closed for any reason

@WheatWizard Looks like the specific case got fixed, but I think it's still generally doable

@cairdcoinheringaahing you'd need a ton of answers though since the badge used to be off score alone

but it does seem like under that situation it'd still be possible

caird coinheringaahing

I can just imagine someone with 200 answers in graph-theory, all scoring <2, and one super high scoring answer to a non-graph-theory questions, then editing the tags and getting the badge :P

Luckily tho, tag badges get revoked if you stop meeting the requirements, so a rollback would fix that :P

5:49 PM

oh you can lose tag badges if the condition later becomes false?

caird coinheringaahing

Yeah. If you delete answers, or get heavily downvoted, it gets revoked

oh cool

can stuff like nice question be revoked

caird coinheringaahing

No, tag badges are the only badges that get revoked

okay

and you can only get them once, right? :P

caird coinheringaahing

Normally, yes :P

"SQL is a quality language"

(or replace SQL with one of Python or JS (if that's not your sort of thing))

But SQL literally stands for "SQL is a Quality Language"

so you can't just replace it with Python or JS

Redwolf Programs

lol

caird coinheringaahing

@LuisMendo "JS's type system is amazing"

"Languages are basically the same"

^

6:19 PM

coding is easy; just typing

(want to say "it's just typing" but that won't fit)

wait: coding's easy, it's just typing

Redwolf Programs

"Can you fix my computer"

caird coinheringaahing

"You're tech support, right?"

I mean I work as a software dev and it is mostly just typing.

I don't really come up with algorithms or solve problems.

i mean even if it's just typing it's more of the idea that "coding isn't a hard job because you just sit there and type, it's not a job that requires skill" though i can't fit that sentiment into 5 words

I just add fields to the json or yaml, or move things around in the js.

I mean it's basically right though.

caird coinheringaahing

6:22 PM

Coding's easy right up until it isn't

There is a very low level of basic skill that is required. But 90% of the stuff you learn at school is just basically irrelevant. You can get the skills to be a professional dev in a month or two.

that's fair

@user Nice and simple, easily generalizable to other professions

@WheatWizard Wait what?

caird coinheringaahing

@user That's going to be a fun notification for Luis :P

Yeah, posting that wasn't a good idea

@LuisMendo Real programmers use butterflies

6:24 PM

@user I haven't written an algorithm at work in a very long time. It's just string together library calls, or move this around or change a config file. It's not a technically demanding job.

What about design patterns and all of that other stuff?

caird coinheringaahing

@LuisMendo "Only amateurs use Stack Overflow"

lol, I've never heard of anyone actually following design patterns.

@LuisMendo John Skeet isn't a god

@WheatWizard o.O

Just imitate the existing code base, or if your starting a new one just imitate one of the other ones.

6:26 PM

I think I need to rethink my life now

@WheatWizard Wait, so what skills do you need to become a good developer?

caird coinheringaahing

The ability to sit at a desk for 8 hours

^

~~That's not going to be easy until I'm 21~~

You need to know a bunch of arcane facts how the specific environment you work with functions.

You also need to know the very basics about control flow etc. Can't get around that.

So just learn through tutorials and sites like Stack Overflow?

6:29 PM

i started my current co-op last monday and so far all i've done is watch youtube tutorials on spring boot, look at udemy courses about docker (and soon angular and kubernetes in the next few days), and look stuff up on stackoverflow lol

Or not even that much?

Usually the firm has a bunch of in house specific stuff.

and i suspect wherever i work next, i'll need to do pretty much the same stuff with whatever tech they're using there

So you need to use their docs, or in the nearly guarenteed case where those docs are completely incomplete you need to ask more senior devs.

caird coinheringaahing

90% of my 2 software dev jobs have been googling how to do something on SO

6:30 PM

That's good (?) to know

I strongly dislike software development. Can you tell?

caird coinheringaahing

I really like coding, but never want to have a proper job as a coder. So far I've just done a couple of freelance stuff where they paid me to write an program or two, and even that was only because I was broke

Yeah, I like coding and problem solving. But in an efficient workplace you will do as little of that as is possible.

caird coinheringaahing

Hey @bobble, how's things?

Really killing the excitement I have for an internship thing coming up :P

caird coinheringaahing

6:35 PM

@rak1507 Some people do enjoy it, others don't :P

The easy thing is to get rejected by everyone :P

@user in life or in jobs?

or both?

Internships are different. Either you do nothing at all, or they have you do all the fun stuff.

@rak1507 That hurt

@cairdcoinheringaahing movies in class :)

6:36 PM

@WheatWizard hopefully it'll be the second one

But I was talking about jobs

although it's not really software dev so who knows

caird coinheringaahing

@bobble Sounds fun :P Any good ones?

Interstellar

Ooh, that's a nice movie. Didn't quite understand most of it, though

caird coinheringaahing

6:37 PM

How long are your classes lol :P

Isn't Interstellar like 3 hours long?

We've been watching it for a few days

Probably in detention /s

Nice break after the AP Phys test is over

7:00 PM

I haved used .replace(1/0,0) in javascript and now I'm a monster

7:26 PM

Using JS already made you a monster :P

it's better for golfing than $otherlanguageavailablethatIknow

Redwolf Programs

.replace(1/0,0)...when would that even be useful?

I had to output zero where I would out put infinity. Do you have a shorter one (in JS)?

Redwolf Programs

Depends. Why's the output a string?

|0 (if you're dealing with ints)

7:30 PM

it can be a string or anything, it will be coerced to a string

Redwolf Programs

Not by .replace

Infinity|0 is 0, n|0 is n where n is an integer

Redwolf Programs

@rak1507 But only between -2b and 2b

@rak1507 oh wow that works

Redwolf Programs

It wraps around otherwise

7:30 PM

true

although I'm not actually sure if the input contained floats

Redwolf Programs

Link?

@RedwolfPrograms codingame.com/multiplayer/codegolf/temperature-code-golf

ah, this badboy

Redwolf Programs

1/x?x:0 should work for floats, but it's longer

7:33 PM

well I'd still need to store in x for that

caird coinheringaahing

1/(x=..)?x:0?

Redwolf Programs

I think you would for any solution involving floats

@cairdcoinheringaahing yeah that works

* Wezl slaps floats around a bit with a large trout

Redwolf Programs

1/(1/x||1/0) maybe?

No

That's long now though

And still wrong

Wait it's correct but still long

the .replace is nice and readable :) even if it does crazy type coercion

Redwolf Programs

7:36 PM

You have to stringify it first though

(1).replace is undefined

You'd have to do (1+"").replace

I never bothered to convert it to a number in the first place :)

CMC: Determine if a number is -1

I found a really neat JS solution

caird coinheringaahing

0 bytes; outputs -1 if it's -1 and something else otherwise

‘ in jelly if I can output 0 (falsy) for -1 and truthy otherwise, otherwise ^^

or ‘¬ for 2 bytes as well

first attempt is 109 chars lol

@Wzl how long is your solution for that

7:42 PM

Haskell (-1==). (I am very clever)

Redwolf Programs

can I see it?

4 bytes? i'm definitely missing something lol

caird coinheringaahing

Spoiler for Jelly

i don't supposed "sort by (-abs(x), x)" is short enough :P

caird coinheringaahing

Even sort by -abs(x) is 4 bytes :P

yeah :p

Oh. I saw the 8 at the end and thought it was right :P

8:26 PM

the last room active other than this one is from 3 mins ago, so i just relied on them not sending a message, replied to caird's message above mine, added 1, and deleted the reply :

I was trying to do the same thing, but I did math wrong.

(how is th- wha- ??)

(how is that mod abuse D:)

Or typed a number wrong, but that seems slightly less likely.

@RedwolfPrograms But you edited it!

what is this FKEY

Redwolf Programs

@WheatWizard That was just formatting stuff

It's not against the spirit or anything :p

8:37 PM

But the rules ...

Redwolf Programs

I can repost it with the slight edit then, I don't see a point though

I think the main point of that rule is to prevent checking what the id is then editing it in

All I did was add the _=> and .message_id to make it a function

caird coinheringaahing

@RedwolfPrograms Still, it breaks the rules, so the mods are going to have to eleven it :P

Redwolf Programs

@flawr It's just a GUID used to authenticate you in chat (so very not good to post), you can find it with fkey().fkey in the console

That since= should be 0 I was testing something

It doesn't seem to have any effect on anything though
