@pxeger Are baths really relaxing? I'd be in constant fear of getting my toe stuck in the drain

Wheat Wizard

How does a shower reduce that fear?

I apologize, I just realized I may be creating a new fear for you.

user

It doesn't, but somehow it makes me feel slightly less helpless because I'm standing :/

caird coinheringaahing

Showers let you be as far away from the drain as possible

user

Movable heads are a blessing, yeah

Wheat Wizard

You can put your head on the drain side right?

caird coinheringaahing

13:03

Yeah but then your butt can get stuck in the drain

Wheat Wizard

And also isint the drain on the bottom of the tub? Usually when I lie down my toes stick upwards.

user

^^

@WheatWizard ¯\_(ツ)_/¯ I've never bothered taking a bath before, maybe it isn't that bad

Wheat Wizard

Also don't your shoes protect your toes? Or do you bathe with open toed shoes? So many questions about this fear.

user

Wait you guys bathe with shoes?

caird coinheringaahing

Yeah, my bath shoes

user

13:04

I've been showering wrong all this time?

Wheat Wizard

Protect from athletes foot.

user

...I can't tell if you're kidding

caird coinheringaahing

@user I bet you shower naked as well instead of wearing a winter parka

user

@cairdcoinheringaahing No, I use a raincoat, too afraid of water for that

Wheat Wizard

Why would you wear a parka in the shower?

^^

Raincoat is a much better idea.

caird coinheringaahing

13:06

@WheatWizard Because of the cold water

user

(I actually dislike my feet touching water tho)

caird coinheringaahing

How else are you supposed to stay warm?

user

With hot water, as hot as you can make it

Wheat Wizard

@user But you can keep your feet dry in a bath! Just put them on the rim of the tub while you recline. You can't do that in the shower.

@WheatWizard I can't believe I didn't think of that before! I'll try bathing tomorrow for sure

@cairdcoinheringaahing which one?

hyper-neutrino

@cairdcoinheringaahing done, good suggestion

@cairdcoinheringaahing the government issued an amber alert at 3:50, which is alright because if i get woken up i can fall again soon enough, and then another one at 4:10, and so i really didn't sleep well

caird coinheringaahing

@Wezl Both, but the latter one rings a bell

hyper-neutrino

doesn't help that i didn't go to sleep until 3:30 which is my own fault, but still

caird coinheringaahing

13:37

Lyxal isn't a room owner?

hyper-neutrino

@cairdcoinheringaahing they (CGSE) have their own room

@CodeGolfStackExchange Please don't talk about that here. You'll find that people who are interested in that room will probably see things in that room. It's getting a bit repetitive and uninteresting.

@hyper-neutrino that seems pretty bad

@hyper-neutrino heya, need your help 🙃 Can you give chat.stackexchange.com/users/513713/user1013431 write-access to the apl orchard? (chat.stackexchange.com/rooms/52405/the-apl-orchard)

StackMeter

@RGS seems a bit sussy

hyper-neutrino

@RGS done. not Adam asking this time? ;)

RGS

@StackMeter Nah, it's fine. People from outside occasionally request access to the orchard.

@hyper-neutrino Thanks a lot! <3

StackMeter

you seem to be a trustworthy user though

caird coinheringaahing

@hyper-neutrino Do you have a link for your "room to transcript" userscript?

hyper-neutrino

13:58

@cairdcoinheringaahing I'm just using Samuel Liew's Chat Improvements userscript, which includes... a lot more than just that.

RGS

@hyper-neutrino sorry if my request for help was too cold :/ but thanks for this!

hyper-neutrino

(on chrome; I never reinstalled it on Firefox so I just manually go to the transcript each time)

@RGS nah, I'm used to just a ping + "can you grant <> access to <>" :P

RGS

@hyper-neutrino that doesn't make it any less rude :P

hyper-neutrino

@RGS fair enough :P don't worry about it there was nothing wring with your request at all :D

caird coinheringaahing

@hyper-neutrino This is basically just a complete chat redesign :P

hyper-neutrino

yep :P

user

Wow, that's a lot

hyper-neutrino

it's annoying because reputation changes and inbox items show up in the header but when I expand them, it doesn't show stuff from SO Teams

so i have a notification but can't read it

caird coinheringaahing

Imagine using Teams. Made by the "I'm still not entirely sure what Teams is" gang

hyper-neutrino

this is almost definitely a bug; teams postdates chat so it's not surprising that chat doesn't see notifications from it

@cairdcoinheringaahing it's sort of just similar to SO but with the reputation thingy cut back a lot and it's private and you can ask specific people questions

you can also ping anyone you want in comments even if they haven't been to that post yet

user

Ooh, i can scroll through the starboard now!

hyper-neutrino

14:04

there's a lot of other stuff but that's the main thing i remember

i don't use it all that much

caird coinheringaahing

@user Oh, that's helpful

hyper-neutrino

oh jo king is not spacing out edits as much as I was :P

caird coinheringaahing

The text box resizing isn't great actually. Causes stuff to move around when I move my mouse over them

hyper-neutrino

yeah, it does too much for my liking

user

@cairdcoinheringaahing In the starboard? I think that's alright, you can see the rest of the message without clicking on it

caird coinheringaahing

14:07

@user A bit in the starboard. But also, I'm currently in 22 different rooms and it doesn't have the normal chat ability to only show the top 5, so the starboard is tiny for me

Wezl

@cairdcoinheringaahing looking through balanced-string, I don't see any duplicates IMO, thought there are some "complete parentheses" challenges. I'll rename it to "close my superparens".

caird coinheringaahing

Plus, hovering over the room description

hyper-neutrino

one userscript that's cool is this which makes it so when you click images in chat it gets lightboxed rather than opening in a new tab, and makes images show up in the starboard rather than just being imgur links

user

Oh yeah, that's a little annoying (but worth it imo)

caird coinheringaahing

Interestingly, it doesn't highlight HN's messages in the chat, but does with every other user when you hover over them

hyper-neutrino

14:09

TBH the main change I want is the ability to hover to expand starboard items and the transcript redirect

user

@cairdcoinheringaahing Might be the diamond

hyper-neutrino

like you mean people pinging me? yeah that's probably the diamond

@Adám ok

you get one if

but it must be in a recursive function

Adám

@Adám In comparison, the normal solution is ⊢≡⌽

user

@Adám If your language has a short-circuiting or, I guess you can get away without an if, but yeah, doesn't make sense to ban control flow

StackMeter

@user see above

caird coinheringaahing

Imagine using if when you can use for instead :P

user

@StackMeter I don't understand. Why do you want to ban it?

StackMeter

15:04

@user because people find workarounds

for example, Adám's solution

user

Workarounds to what? Recursion?

StackMeter

@user yes

user

I mean, since this is a CMC, you can just ask people to use recursion, and they will

StackMeter

ok

hyper-neutrino

but even that's not very observable like

can i just do like

user

15:06

Banning control flow can make certain tasks extremely hard, especially if you want people to use recursion (again, doesn't matter since it's a CMC, but still)

@hyper-neutrino It's a CMC, doesn't have to be observable

hyper-neutrino

lambda x,y=0:y or x==x[::-1]and f(x,1)

that technically recurses

StackMeter

let me go think of a better example

Wezl

@StackMeter f=(a,r=0)=>r?a==a.reverse():f(a,1)

@hyper-neutrino It's not just technical - anyone would agree it recurses (with an f= at the start)

right forgot about that

Redwolf Programs

Looks like the newest Tampermonkey update would have fixed the issues with RSR I was having, but GRT's better anyway IMO :p

caird coinheringaahing

I know what merge sort is

@RedwolfPrograms Personally, the biggest pro of GRT is that I can have /review pinned as a tab and it opens new tabs for me. RSR would load the task into the tab, and there'd be no change if it was pinned

Redwolf Programs

I do like your suggestion of changing the favicon for review tasks, but I'm not sure what to change it to.

What's the context here for discussing mergesort?

I actually really like mergesort.

user

Tim doesn't.

caird coinheringaahing

@user easy. Jelly, 1 byte Ṣ Note: not guaranteed to actually use merge sort :P

user

Tim hates mergesort so much he made his own sorting algorithm.

And you know why Tim hates mergesort? Because you like mergesort. Tim hates everything about you ROs because you fired him

Redwolf Programs

No, just removed his most important jobs :p

user

He depended on that job to feed his 32 children

@cairdcoinheringaahing Python uses Timsort, and Jelly's built in Python, so that's invalid, I think :P

Timsort's only half mergesort

hyper-neutrino

15:42

implementation specific :P

i doubt python has a spec for what algorithm sort must use

and jelly's implementation-defined but it doesn't require you to use CPython i think

user

@hyper-neutrino We define languages by their implementations here though

hyper-neutrino

right but jelly is defined by its implementation but the underlying python doesn't have a required implementation and therefore we can say "jelly being run on an impl of python that uses merge sort" :P

Well "python" isn't a single language then.

@hyper-neutrino imgflip.com/i/5c3uuu

@hyper-neutrino Bah, too much intpicking here

Wheat Wizard

15:44

Well python 1 is older than timsort so I would assume it doesn't use timsort.

And early versions of python 2 are also older than timsort.

user

They likely used quicksort, then

Wheat Wizard

Why?

user

Because quicksort is quicker than mergesort, duh

Wheat Wizard

Yes but mergesort is mergier.

Redwolf Programs

Mergesort's faster in some situations though, right?

caird coinheringaahing

15:46

@hyper-neutrino My goal for my Add++ rewrite is to be able to write a Jelly interpreter in it :P

Redwolf Programs

I don't know much about the differences, because I strongly dislike quicksort, but from what I've heard the difference isn't significant enough to not just use mergesort

Wheat Wizard

As a general rule of thumb any sorting algo is going to end up being faster in some situations.

hyper-neutrino

quicksort's effectiveness is dependent on your pivot selection algorithm

user

@WheatWizard Oh, you're right

hyper-neutrino

mergesort is more consistent

@cairdcoinheringaahing sounds slightly painful :p

Redwolf Programs

Q: When merge sort is preferred over Quick sort?

algorithm sorting quicksort mergesort

John Dvorak

mergesort requires a side array though

user

I think quicksort also requires an extra array ~~(a smaller one, though)~~

hyper-neutrino

15:49

you can merge in-place

quick sort is usually not stable, though it can be at an extra memory cost

user

Completely in-place? How?

hyper-neutrino

@user probably a relatively naive two-pointer approach should work

Redwolf Programs

Unstable sorts are objectively bad

Mergesort ftw :p

user

@RedwolfPrograms Unstable sorts of people, or just algorithms?

Redwolf Programs

Algorithms

user

15:51

Phew

hyper-neutrino

just take your list, divide it, recurse, and then to merge, you set a pointer at 0 and a pointer at middle, and then each time you sort the two pointer values with an in-place swap (ok technically O(1) memory then, not O(0)) and then advance the left pointer

or something like that

i could write up a quick implementation but i don't feel like it

Redwolf Programs

I intuitively understand how mergesort works a lot more than quicksort, which is also another factor in why I prefer it :p

hyper-neutrino

my understanding of quicksort is basically you select a value and then take in your values and divide them based on if they are >= or < that pivot

user

@hyper-neutrino Oh that's smart

hyper-neutrino

and now you can just recurse on each side

user

15:53

But if you have more < values or more >= values, you need an extra array to store those while adjusting

hyper-neutrino

you could do a pretty naive in-place partition if you don't care about stability

Redwolf Programs

List of pets I want:
1. Gray fox

You want yourself as a pet?

hyper-neutrino

and i am convinced you can get around that by sacrificing a bit of time

Redwolf Programs

15:58

Mergesort just does that by default though :p

user

TIL I don't know much about sorting algorithms at all

Redwolf Programs

Plus merging things is fun

user

@RedwolfPrograms Stability isn't always needed ¯\_(ツ)_/¯

hyper-neutrino

15:59

I could sit down and write an implementation of merge sort on five minutes. For quicksort, I'd almost certainly have to google and copy someone else.

hyper-neutrino

to merge sort, you split your array in half, recursively merge sort each half, and then run a two-pointer to in-place merge both halves

to quick sort, you select a pivot, run a two-pointer from both ends of the array to partition both halves, and then recurse
