@lyxal What was this?

lyxal

res

The tio version doesn't work, but github.com/Lyxal/res is a clone of how it was pretty shortly before deletion

It hasn't had any commits for 3 years, so it wasn't modified before the answer was posted

oh cool i have been in tnb for 1 year and 2 days :p

emanresu A

Cool :P

PyGamer0

officially completed one year of tnbing :p

emanresu A

Any final feedback?

Unrelated String

maybe add a testcase with leading/trailing non-word characters

i don't necessarily expect that to trip anyone up but coverage is coverage :P

alright @des54321 @emanresuA how does this grammar look?

^ feebcake on that grammar?

Jo King

05:48

@PyGamer0 shouldn't it be (expr";")*?

PyGamer0

06:10

@JoKing oh yeah thanks

Q: Is it a heapable sequence?

We say a sequence of integers is heapable if there exists a binary max heap, whose nodes are the sequence's elements, such that if \$p\$ is the parent of \$n\$, then the sequence has \$p\$ before \$n\$. Alternatively, a sequence is heapable if we can initialize a binary max heap whose root is its...

Q: Truncate words in a sentence

Inspired by wezl. Your challenge is to take words (sequences of [a-zA-Z]) and truncate them to length 3. For example, never gonna give you up would become nev gon giv you up. Words will not necessarly be delimited by spaces - for example, youtube.com/watch?v=dQw4w9WgXcQ will become you.com/wat?v=...

For my desmos challenge in the sandbox, fireflame put an easier process to construct bernard in the comments, should I replace my explanation with that easier explanation, or should I keep my initial explanation? Which would y’all think is better overall for the challenge? On one hand, it might be interesting to see how ppl puzzle out golfier strategies of constructing bernard, but on the other hand, that might just be annoying and be a detriment to the challenge.

DialFrost

Sup guys how ya doin

Aiden Chow

@DialFrost good hbu?

@emanresuA The plot thickens: Today, my comment flag limit was 54. Today, I've raised 60 comment flags. If I've kept count correctly, 12 of those required manual review before being approved; the other 48 were validated automatically.

Wheat Wizard

12:37

@pxeger I think 13 of your flags were manually reviewed.

pxeger

Hmm, ok

thejonymyster

15:32

@AidenChow your last bernard is only 15 tall, also yes you should include the easier recursive definition probably, as long as its actually accurate to the shape

PyGamer0

16:35

umm ok i guess

and they temporarily starred flax :p

because they might have thought that flax is some language designed for hacking into systems or something lol

user

Are there languages specifically made for hacking?

PyGamer0

i dunno

probably

Wheat Wizard

@user I'm not sure if it was intentional design, but php is great for hacking. Careless developers will easily create vulnerabilities.

pxeger

@user I know of pwntools, which is a library/framework for "hacking" in Python

pxeger

17:21

Any feedback?

des54321

@WheatWizard thats less "made for hacking" and more "made for being hacked" though

@WheatWizard Why did you add a note about scoring in characters to codegolf.stackexchange.com/posts/8696/revisions? Was our default not to score in bytes?

Wheat Wizard

@pxeger I don't know precisely. The challenge itself was posted in 2012 at which time the default would have been characters, but I think bytes were default well before 2018.

pxeger

Based on the language-agnostic tag, might it have been migrated from SO?

caird coinheringaahing

No, it was posted here

Migrations are shown in the revisions

pxeger

Hmm

Why did we have that tag then?

caird coinheringaahing

But, back in 2012, things were still done similar to the SO way. You could find a decent number of language specific challenges then

Ginger

19:16

fear not, I am still alive

ais523

there used to be a pages that listed recent reviews of a particular type, by anyone

but I can't find it nowadays

has it been removed, and if not, what is the URL?

caird coinheringaahing

There's a /history page for each review queue, e.g. codegolf.stackexchange.com/review/close/history

pxeger

codegolf.stackexchange.com/review/close/history?

caird coinheringaahing

But, I think you can only see the full history if you have 10k+ rep

ais523

that exists for me (on a site where I have enough rep to review), but it only shows my own reviews

ah, there's a rep limit, that would make sense

caird coinheringaahing

19:20

I'm happy to find a specific one if you need it

pxeger

Do you have this toggle?

ais523

I don't

so, rep-limited then

caird coinheringaahing

@pxeger This is behind a rep barrier

pxeger

yeah that must be it

ais523

I wasn't really looking for a particular review, just curious about what was being reviewed nowadays

and was wondering if there was a less time/bandwidth-consuming way than guessing at review URLs

caird coinheringaahing

19:21

Yep, 10k rep:

> You now have access to [...]
The full history of reviews by all users in any review queue

ais523

in that case I probably need to report a bug about this on meta SE, that 10k information is available to anyone with enough time on their hands

caird coinheringaahing

@ais523 Review IDs are consecutive, and we're currently at around 65900, so you can somewhat manually check them out

ais523

that's what I was doing

unfortunately, you do have to specify the queue it's in, so six URLs to check (although checking low-quality posts first probably cuts the time down a bit)

caird coinheringaahing

@ais523 tbh, most rep-limited information is available if you put in enough effort

Site analytics can be tracked via SEDE for example

ais523

I imagine that much of it is available via SEDE

caird coinheringaahing

19:27

Yeah, generally, they don't really care that much about hiding information, more about giving people increased capabilities/responsibilities

Ginger

OLIMAR is back online

speaking of which, did I tell yall I finally found a good process-monitoring tool?

it's called Supervisor: supervisord.org

ais523

thanks

pxeger

@Ginger you mean like a service manager? You could try looking at things like ~~tini~~

ais523

init doesn't really monitor processes

Ginger

19:34

I like Supervisor because 1. it has a web interface and 2. it's written in Python

pxeger

if your system already has systemd, I'd say use that

ais523

it only really has two essential jobs: a) to act as a "default" parent when no parent process is available (and do the jobs of a parent process, like waiting on its child processes); b) to start the events that start the system in motion

systemd contains an init, but is much more than an init in practice

Ginger

but why should I when this is working fine and is easy for me to use and extend?

pxeger

it may be controversial but it has plenty of features, and is pretty reliable

caird coinheringaahing

@pxeger I saw 7 links, and thought you'd included the last history of /first-posts, before remembering that we have 7 queues now :P

Ginger

19:35

if it ain't broke don't fix it

ais523

"Solve an NP-Complete problem with polynomial average time" – I'm glad I started looking at this now

@pxeger Rounding errors, or you had some flags left from the day before modulo 10

thejonymyster

21:18

question that might sound off topic but im thinking about challenge ideas lolol: are there any relationships two like.. integer arrays might have with eachother? like in the same way that two shapes might be duals of eachother

i keep going to call it a "property" of the thing but that doesnt make sense

like you might say like, [1,2,3,4] and [4,3,2,1] are reverses of eachother, or [1,2,3] and [-1,-2,-3] are negatives of eachother

caird coinheringaahing

@thejonymyster Yes, lots lol :P

thejonymyster

where can i read up on this :)

oear (online encyclopedia of array relationships)

caird coinheringaahing

But, you might be interested in Binary relations, but where the domain/codomains are \$\mathbb Z^n\$ (i.e. integer lists)

thejonymyster

ooooooh yes yesyesyes

thank you :-)

ooh just from this ive already got one thats caught my attention lol

[1,2,4,6,7] and [3,5,8,9,10] may be considered "complementary" to eachother :P

caird coinheringaahing

For what its worth, as I don't think that article explicitly says it, IIRC a relation ~ satisfies reflexivity (x ~ x is always true), symmetry (x ~ y = y ~ x) and transitivity (if x ~ y and y ~ z, then x ~ z)

thejonymyster

21:24

ooh ok that doesnt strictly fit the thing i just did :P

caird coinheringaahing

Tho I may be misremembering my proofs course

thejonymyster

still interesting, and i remember hearing about that in a video about equivalence operations

or what ever it is called

caird coinheringaahing

@cairdcoinheringaahing Sorry, yeah, if a relation satisfies these axioms, it's an equivalence relation

I can math, but not after 10pm :P

emanresu A

goto sleep;

caird coinheringaahing

It's half 10, no :P

emanresu A

21:28

I tried

And I doubt I'll ever succeed

thejonymyster

S(emanresu)

caird coinheringaahing

CMC: Given a binary function \$f : X \times X \to \{\text{True}, \text{False}\}\$ for some finite set \$X\$, output a true/false value to indicate if \$f\$ is an equivalence relation; that is, does it satisfy the axioms of reflexivity (\$f(x, x) = \text{True}\$), symmetry (\$f(x, y) = f(y, x)\$) and transitivity (if \$f(x, y) = \text{True}\$ and \$f(y, z) = \text{True}\$, then \$f(x, z) = \text{True}\$)

des54321

is it just me that all of that mathJax isnt rendering for, or do you have a userscript that makes it work in chat?

att

it doesn't render for me either

emanresu A

^'

user

21:50

There's a userscript for it (ChatJax)

@des54321 github.com/vyznev/chatjax

caird coinheringaahing

@des54321 I have a userscript

Plus, after a year of writing almost exclusively in latex, I can read raw latex at this point :P

user

Hmm, perhaps I should consume more latex too to gain this power

des54321

@user aaaaand this doesnt work with firefox/greasemonkey apparently, installed and im still seeing raw mathjax

user

Did you reload and everything?

des54321

reloaded, force reloaded, nothing

caird coinheringaahing

21:53

@user My diet consists of entirely condoms and balloons. You cannot approach the power I have :P

user

Ah, but I eat gloves

caird coinheringaahing

github.com/cairdcoinheringaahing/Tampermonkey/blob/main/… works on chrome

user

I shall take 5 biology lab classes if that's what it takes to defeat you

caird coinheringaahing

Only dentists have even a fraction of the power I have, and that's only those that dispose of their gloves by eating them

des54321

@cairdcoinheringaahing working beautifully, there we go

caird coinheringaahing

21:55

Or by injecting them between their toes, but we don't talk about them

des54321

wait no its not

im blind

user

You've just given me an idea - get bad teeth and eat the dentist's gloves when they put them in my mouth

Maybe this question will lend some answers?

Oh wait, this isn't Off-Topic TNB

des54321

@user it might, but I dont feel like digging around with javascript and trying to debug it right now

emanresu A

22:36

@user This conversation is scaring me

thejonymyster

23:17

@cairdcoinheringaahing ill die before i use chrome :P

or was it the other way around..

Radvylf Programs

When you die, you either start using Chrome or Firefox. Depends on if you committed any sins against web development. People who have done especially horrific things get sent to Internet Explorer.

thejonymyster

when i die, fuck it, i wanna go to dell

emanresu A

@RadvylfPrograms People who have done moderately horrific things get sent to safari on ios.

user

@RadvylfPrograms Which one do you go to if you commit sins against web development? Because both are about equally good/bad

And what's the threshold for being sent to IE? Asking for a friend

Radvylf Programs

@user Depends on personal preference

And old people who retired from committing sins against web development are sent to Netscape Navigator

user

23:27

~~Why are you punishing old people?~~ Oh, specifically old people who used to commit sins

Radvylf Programs

@user Well, anyone who overrides how scrolling works, for one

user

I've done that on Macs before (if you mean simply changing the direction)

Radvylf Programs

You monster

user

It's in the opposite direction from what I'm used to

Radvylf Programs

Oh well I mean on a publically accessible website, changing how scrolling works

user

23:29

Oh, for other people

Radvylf Programs

Yeah

user

Well, I didn't do it on a website, but I did do it on a shared computer

Also made the accent color yellow, turned off the touchpad, and some other stuff

If a friend aliased nano and vim to ed and cd to rm -rf but it was in a VM, will that friend be sent to IE?

Radvylf Programs

Has nothing to do with web development so no

But you may be resurrected as someone who uses Gentoo

user

@thejonymyster Thinking of a funny response to this but all I could come with was "when it go to fuck dell, i, i wanna die," so I wasn't going to post anything, but then I thought "what the hell, my reputation as a sensible member of TNB is shot anyway" so I'm posting this message

@RadvylfPrograms I mean, I've always wanted to be that cool

I have no problem with being shunned by the rest of society because that'll happen anyway :P

The only thing I have a problem with is being resurrected. Life can lead to many undesirable things, including cancer, pain, embarassment, and death

thejonymyster

one might argue that all computation is sin

user

23:36

How so?

thejonymyster

2+2=4 ? bah! who are you to say what should happen come two and two join together... tis soothsaying, blasphemy!

idk lol

user

I mean, that's just how, 2, +, =, and 4 are defined

You can define them in such a way that 2+2=5 if you wish

thejonymyster

lang where 2+2=5

mathcat

Hi guis

it's 1:40 and I don't want to sleep

I can't figure out why my fetch isn't working

Radvylf Programs

Might be CORS

mathcat

23:46

what's that?

btw I'm trying to fetch localhost, would that work?

Radvylf Programs

Only from localhost

Unless you add an Access-Control-Allow-Origin header to the resource being served from localhost

mathcat

ah thanks

thejonymyster

you know what the oeis needs? sequence rating

Radvylf Programs

Ooh yeah

thejonymyster

and a "hottest sequences" tab

mathcat

23:48

Only if Neil won't decide to remove dislikes

Radvylf Programs

"5 stars, cool sequence, would enumerate again"
"1 star, just a ton of ones and twos"
"3 stars, some of the integers are missing"

Seggan

Please review my updated list of Fig operators

thejonymyster

whats with m&

like, as in why m

i like the - and / string overloads

also : is interesting, when do you think that might be useful?

emanresu A

@RadvylfPrograms For stuff like say, canvas, you have to choose one way or the other

Radvylf Programs

For stuff like that it's fine yeah

I'm talking about ordinary websites with like, paragraphs of text, but someone decided this would be a great time to show off that they know how addEventListener, preventDefault, and scrollBy work for no other reason than...actually idk

emanresu A

23:57

Yeah, they deserve Internet Explorer
