Q: AoCG2021 Day 16: Interpret Duet

Related to AoC2017 Day 18, Part 2. (Anyone want to add Duet to esolangs?) Duet is an assembly-like language that involves two processes running the same program simultaneously. Each process of Duet operates with 26 registers named a to z, all initialized to zero, except for the register p which ...

adam neely used "relevant xkcd" in a vid lol

@thejonymyster ?

i feel like thats a phrase used a lot around here

from what i have seen

or in these circles

oh and timestamped because i forgot to link

unless im just insane or something

oh, you weren't mispelling "nearly"

Redwolf Programs

Capital letters for the win :p

> Explain how political, economic, and cultural factors affected society from 1450 to 1750.

Could this question be any more vague lol

12:21 AM

Explain what happened at some time

@JoKing oh LOL my bad i didnt even think of the adam connection

Redwolf Programs

Ugh, why doesn't gmail send notifications when the tab is closed

how could it?

when i close a tab it has no power over my browser

it is Gone...

Redwolf Programs

It's 100% possible

You could have a desktop client or a browser plugin.

Redwolf Programs

12:26 AM

Almost all sites that you can opt in to notifications for...will send you notifications when it's nt open

This has existed for like...ever

Otherwise it'd be pointless

@Adám That's not at all necessary

How do such push notifications actually work? Who's listening?

Redwolf Programs

A service worker

Push API

But if the browser is closed?

Redwolf Programs

Then no, it's not possible (via the Push API at least)

But who closes their browser anymore?

True.

12:57 AM

I've seen some sites push things directly to Windows notifications, before I open my browser or anything. Wonder how that works

1:12 AM

I assume the browser's running in the background

Discord, at least, has the ability to run in the background even if you "close" it

~~or you've been hacked~~

Rather benign hackers they must be to add features to Bubbler's browser :P

Who knows? Maybe they want the source code of TIB and haven't realised Github exists

@JoKing No one's having fun. They may have smiles on their faces, but inside, they are seething in rage at being trapped in really bad art

> hackers

> haven't realised Github exists

Mad respect to any hacker who can do that to someone's computer without ever encountering Github :P

just saw that outlook decided to mark a github email as junk

well done microsoft

1:18 AM

ಠ_ಠ

isn't github owned by ms........

that's the point

<insert meme of guy shooting himself>

brilliant

and what's even funnier is that it decided to move a Microsoft rewards email into junk as well

1:19 AM

lmao

hey, at least it shows they aren't biased with their filtering xD

The (mostly) benign hackers have struck again!

@hyper-neutrino the github email wasn't even junk though lol...it was a whole bunch of github student developer offers I'm actually interested in lol

1:31 AM

@lyxal half my work gitlab emails get marked as spam by gmail

probably because the subject line is just a name

@Bubbler assuming Chrome, I believe it starts itself in the background and runs in the system tray, specifically to allow things like that to work

@JoKing Doesn't unmarking a few as spam help its algorithm or whatever?

i've tried that, but it's still very suspicious

It must be Edge, because my home computer didn't have Chrome installed when I first saw it

1:49 AM

user image

Can I post messages in read only mode?

Nope

@tjjfvi why?

it's called read-only mode because you can only read the content

although i think read-only on site doesn't always affect chat for the full duration. idk how it works ¯\_(ツ)_/¯

Chat never worked, so they never have to fix it

2:04 AM

We are currently offline for maintenance but Chat?

@emanresuA wdym?

It's a joke because of how unmantained chat is

Lol, they said read only but we can not even read now

Can't break something that was already broken

Redwolf Programs

Chat's back!

It was showing the cat meme for a few minutes for me

loool

2:11 AM

read only mode = prevent from uploading messages

Redwolf Programs

That's for main only, chat doesn't have a read-only mode

in Vyxal, 3 mins ago, by lyxal

Can't break something that was already broken

You got ninja'd

lol i dum

Redwolf Programs

Chat's either broken or it's well...still broken but you can still chat

2:13 AM

Chat really isn't all that terrible, though

It's decent for something that SE's put barely any work into

Redwolf Programs

Also, what color temperature would y'all recommend? I'm getting some new lightbulbs for my bedroom as a christmas present to myself

0K an option? :P

@RedwolfPrograms For the bedroom, I'd go with the lowest temperature (most red).

Redwolf Programs

I'm really not a fan of yellow-y stuff

I have more secret hats then normalones

Redwolf Programs

2:14 AM

I'm thinking 5000K, but I'm not sure if that's too high

The bulb I have now is almost certainly mislabeled, it says 3500K but it's a pleasant whitish color

Actually, 3500k is pretty close to what it is, looking at pictures

So 4000K or 4500K should probably be what I aim for

That's still quite blue for a bedroom, imo, but hey, it is your eyes.

Redwolf Programs

Anything with the slightest hint of yellow/orange is hideous and depressing

The rest of my house has like 2500-2750K bulbs, and I hate it

Oh wait, color temperature really is measured in Kelvin?

Redwolf Programs

Yep

That sounds rather high, though

@RedwolfPrograms that's an error page I think I've never seen before, actually

2:31 AM

Latest macos update is ~29gb (Had to uninstall vyxal to get it because "system data")

@emanresuA under a year

@RedwolfPrograms I wasn't active in chat until ~1k

@tjjfvi A lot of people

@tjjfvi many

Redwolf Programs

Anush?

3:32 AM

@emanresuA one of the mods from another site?

or like Catja or something

Half of that's correct

Redwolf Programs

Jo King?

Correct!

@emanresuA I'll spoil it for you: it was hyper-neutrino

Redwolf Programs

Wait what

3:33 AM

huh?

Yeah :P

@tjjfvi you'll only be cheating yourself

how about i am ascii-οnly? /s

(Note: These are all starred messages I think)

@pxeger That is so cursed

3:36 AM

@pxeger Lyxal?

@emanresuA yeah, I'm taking them from the starboard

@emanresuA you're overthinking it

it was ascii-only

@pxeger Same

@emanresuA Adàm? He also uses that kind of smiley, although I think he normally puts a - nose in his

Nope

What about this: xnor would like to: know your location

that one rings a bell

3:40 AM

Nope

Nope

Oh boy this and its comments are in need of some moderation over on History

I hate the fact that you can't flag things on SE without being logged in to the specific site

Redwolf Programs

Gotta love the classic "CW to make it less obvious a garbage answer is associated with you"

VLQ flagged

(Idk if that's correct)

I get why they do it if you're not logged in at all, but when I'm logged in to several network sites, it really annoys me

@emanresuA moderator attention would be better imo

Redwolf Programs

I already mod-flagged, so it's probably not necessary to do more than one or two of those

VLQ/NAA may or may not be a faster way of nuking it, depending on how active History's mods are, so I'd imagine both are fine

4:07 PM

Should f=a=>a.length>1?a[0]+f(a.slice(1)):a in javascript for input hello return hello and not helloellolloloo?

@RedwolfPrograms A kid at my school suggested the name “Redwolves” for the Washington Football Team” Is he one of your people? >;(

@user wait wat

I’m not kidding

It was in the school newspaper today

Redwolf Programs

@grandBagel Yes

@RedwolfPrograms why?

Redwolf Programs

4:13 PM

It'll always return the first letter, plus f of the rest

So It's "h" + f("ello")

Which itself is "h" + ("e" + f("llo"))

What you're looking for is a+f(a.slice(1))

Not a[0]

And you can golf it by replacing a.length>1 with a, since the empty string is falsy

and you can golf out the ternary and just do a && a + f(a.slice(1))

because a ? b : a is just a && b and a ? a : b is just a || b

Redwolf Programs

Good point

and a ? a : a is ???? :p

Redwolf Programs

With arrays, you can do a+a?b:[] to do something if it's non-empty, a trick I learned from Arnauld

Or, in a lot of cases a+a&&b

Since ususally with recursive stuff you have a ...f(b), so the empty string and empty array behave identically

Is there a shorter way of string.split()? I feel like I saw it in a tips question.

Redwolf Programs

4:19 PM

For splitting by "", [...string]

@RedwolfPrograms I meant splitting by spaces.

Redwolf Programs

.split` `

I don't think there are any clever tricks you can use specific to spaces

There are some really niche ones for comma separated lists, like eval(x) if you just want the last item

ooh hang on

eval([1,2,3,4]+"") is 4

If .at wasn't a thing, this would be useful

So I have f=a=>a&&a+a.slice(1);d=w=>w.split .map(f).It's returning hello worldello world for input hello world. I feel I can but the f function in the map, but then it's not recursing.

Redwolf Programs

You need to do f(a.slice(1))

You're not recursing

I get the expected output with that fix

d("hello world")
 -> (2) ['helloellolloloo', 'worldorldrldldd']

woops

Redwolf Programs

4:25 PM

.replace might be shorter

but now it's outputting hello worldello worldllo worldlo worldo world worldworldorldrldldd

Redwolf Programs

@RedwolfPrograms If you want to join those by spaces afterward

@grandBagel You're running f not d then

@RedwolfPrograms oh

Redwolf Programs

d=w=>w.replace(/\w+/g,f=a=>a&&a+f(a.slice(1)))

This will join them with a space again afterward, if that's needed this is shorter than split and join

@RedwolfPrograms same length

Redwolf Programs

4:28 PM

But it does the equivalent of a .join afterward

If that's required

Just a second option

@RedwolfPrograms Not required, though.

Redwolf Programs

Oh, okay

Remember that golfy Markdown/Scripting Lang idea I was talking about before? I have a tentative not-quite-a-spec written up, which I'll probably change a lot and elaborate on later. Here it is if any of y'all want to check it out: gist.github.com/AMiller42/f0d1196a631f27055ce1133d5a34327c

@RedwolfPrograms I read that as "furries" and was very confused

Aaroneous Miller

@AaroneousMiller for those who have no idea what I'm talking about, I'm referring to this:

Dec 3 at 21:05, by Aaroneous Miller

I'm working on defining a spec for a golfy Markdown flavor, with a builtin scripting language. I'm hoping to make a Turing-Complete flavor of Markdown, which I'm hoping ends up becoming exactly as ridiculous as it sounds.

Redwolf Programs

Looks good

Ginger Industries

thoughts on my challenge?

Redwolf Programs

I'm not sure if it'll be interesting

Actually, I could see it having some interesting approaches

@grandBagel Lõ

@Shaggy How does it work?

Redwolf Programs

5:50 PM

We're approaching the 1 year anniversary of the start of Ash's development :p

@grandBagel L is the constant for 100 and the õ method when applied to a number n with no argument gives you the inclusive range 1-n. Or pass it a numeric argument x and it will give you the inclusive range x-n. LõA, for example, gives you 10-100.
