Q: Is this a Jordan matrix?

Background A Jordan matrix is a block-diagonal matrix where each block on the diagonal has the structure of $$ \begin{bmatrix} \lambda & 1 & 0 & \cdots & 0 \\ 0 & \lambda & 1 & \cdots & 0 \\ \vdots & \vdots & \vdots & \ddots & \vdots \\ 0 & 0 & 0 & ...

@NewPosts i feel like there is some mathematical property of jordan matrices you can abuse to make this really easy

Bubbler

00:22

@hyper-neutrino It is the Jordan form of itself, but computing the Jordan form isn't quite trivial

Unrelated String

what you can abuse is jelly's diagonals builtin

hyper-neutrino

okay looks like my idea was far too complicated lol

i finished with 32 because i was just piecing each individual part together and patching a bunch of random shit together; was gonna try to restructure it but seems you beat me to it anyway

Unrelated String

i'm not entirely sure that my solution is correct considering i went through aƑ@, aƑ, oƑ, and a@Ƒ before settling on o@Ƒ in the middle there

it just passes the test cases and works out conceptually

hyper-neutrino

wait how does this even check the 2 in the last test case

oh wait, because then it's not invariant because the 1 becomes a 2

ah I misread the selfie as being outside the invariance

that's smart

Unrelated String

again, it took five tries to get it right lmao

but thanks

hyper-neutrino

00:26

lol

see i didn't see that idea so i began with basically the same outer structure as yours but with a helper dyadic link, and then didn't validate the 1s so i added an extra check, and then errorred on 1x1s so i added a ? to surround the main link, and by then i'd hit 32 bytes lol

because my solution required iteration so if Head produced a default scalar 0 mine would error whereas yours just simply does not :p

caird coinheringaahing

I started with ŒDḣ2µ...µ/ but it just got too long and complex :/

Redwolf Programs

Same here, with 2

caird coinheringaahing

which appears to happen with answers[0]

@RedwolfPrograms Yeah, my error is after commenting out the var tryitonlineattempt = $(answers[0][2]).find('a[href*=".tryitonline.net"]').attr('href');

So it looks like answers[0] is the issue

Redwolf Programs

I think I figured it out:

Line 862 has a regex for headers

caird coinheringaahing

Ah, it needs the space

The what

caird coinheringaahing

The space after the 1 :P

Redwolf Programs

02:38

The regex is missing the whole id part

So I mean technically it is missing the space :p

But a lot more as well :p

caird coinheringaahing

Changing it to (/<(h\d|strong).*?>(.+?)<\/\1>/ kind of works, but it only shows one element :/

Redwolf Programs

I think I have a fix, lemme test

Just use ( id=\\"[^"]+\\")?

Not .*?

That might have weird other behavior, not sure

caird coinheringaahing

No, that doesn't work

Does (?: ) create non-capturing groups in JS?

Redwolf Programs

Yeah

caird coinheringaahing

Nevermind, that doesn't work :/

Redwolf Programs

02:41

Got it maybe?

There's three places you have to add it

862, 870, 871

I think there's still some parts missing though

Wait yeah, only showing first answer

Fixed

With a one liner, too

Add .replace(/<h\d.*?>/g, function(h){return '<h'+h[2]+'>'}) on line 858

Probably doesn't matter where

I put it after the first replace which seems to work

@cairdcoinheringaahing It looks like this is the issue with headers being edited in all edit diffs

hyper-neutrino

04:32

ideally each part of the SE frontend is a section and each time something gets changed there is a notice under that section

so if your script scrapes all the answers but doesn't care about vote counts or user data, then things that change the profile page HTML won't matter to you

ofc that's a lot of work and just say "hey, we're changing this" is a pretty big improvement over just silently breaking things and leaving people confused

Or move to Rust where everything that is supported for smaller ints (including printing in decimal) is also supported for u128 :P

@Bubbler but what is the golfiest answer?

hyper-neutrino

or use python where you can essentially ignore size limits for integers altogether :p

AviFS

Help request

Anush

@Bubbler what do need to actually print it using that?

AviFS

I don't really get APIs, even though I have tio-api, haha

Hoping to use google translate for a webapp

But it looks like their api limits you to 50 requests, even though you're not limited when you use the web interface yourself

Link to api thingy I found

The question is, surely there's a way to figure out what JS is firing on google translate, and/or what PHP it's posting too, and then do that ourselves for free?

Bubbler

05:39

@Anush char* s = uint128_to_str(n); printf("%s", s);

AviFS

Does it not work that way, can you lock the PHP functions away with a secret key or something somehow so that just having the JS doesn't give you access to all the functionality?

On second though, I guess something like this is maybe done re: passwords and admin stuff on websites?

Bubbler

@AviFS I think such a request would be accepted by the server only if it comes from *.google.com or something

AviFS

Alternatively, do you guys recommend any reasonable natural lang translating stuff for JS?

It actually only has to translate a single word

So good english-XXX dictionaries which are easy to parse online would do the trick!

@Bubbler Why didn't I think of that! Thanks

Is anyone else surprised that using google translate programmatically costs money? Maybe I should be

@Bubbler But then I was thinking it must be possible act like a human. Eg have a bot thing fill out the textboxes, and report the result. Does anyone know how to do that in JS? Or if maybe google translate would stop you?

I think I've done more than 50 searches in a day, so I'm pretty sure they don't stop you as quickly.

Bubbler

@AviFS Wait, that's not even a Google-official thing, it's a 3rd party service

AviFS

Oh, you sure?

Maybe google has a partnership?

But so there must be a way to have a bot fill out the form and report the output. Does anyone know how to do that in JS or what to look up?

Isn't that similar to what the chat bots here do?

hyper-neutrino

05:49

if you want to determine how data is being sent

you can usually open the dev tools, navigate to the network tab, and click the submission button, and it will log the request, which you can copy as a CURL or a JS fetch (among other things)

that's how I determined the request formatting for deleting and pinning chat messages, which I use for Vyxal Bot

AviFS

Ooh, thanks I'll try that

hyper-neutrino

i am not that sure about the trustworthiness of the resource you are looking at

but if you've done your research on it then cool

Bubbler

Bots usually don't fill out the form in an HTML document. They just construct a request, send it, and receive the response from the server

hyper-neutrino

yeah

AviFS

@Bubbler Oh, okay thanks!

@hyper-neutrino Hmm, which is the submission button?

hyper-neutrino

05:52

filling out the form and submitting it with the network tab open usually lets you see what the nature / format of the request is, but it might not work

AviFS

hyper-neutrino

@AviFS i don't know, whatever form you're trying to fill

AviFS

Oh, that's what you mean!

I thought in the network tab

hyper-neutrino

i don't actually know what you're doing i just know how to determine request format by doing the request yourself and copying it out of the network tab

ah

Anush

@Bubbler thanks! Still not very golfed :)

AviFS

05:53

I found two potential things. Mind walking me through what now or sending a link/search terms to figure it out?

Oooh, okay

So if I hit 'copy as curl' then I get a command I can run in terminal

And presumably in most prog langs

hyper-neutrino

it might help you more to copy as fetch

AviFS

@hyper-neutrino I was just going to say!!

Bubbler

@AviFS It is powered by a company called RapidAPI, which is a totally separate thing from Google ("Google" appears zero times on its About page)

@Anush Well, what do you expect for something that isn't natively supported :P

AviFS

@Bubbler Google does also have this product though:

cloud.google.com/translate

I did find this: matheuss/google-translate-api

Forgive my ignorance but does anyone mind clarifying this npm stuff for me, please?

Bubbler

@AviFS That is a Google-official thing, of course

AviFS

06:02

So it's happened a few times that I find a GH project that looks to be written in JS

But it has instructions to install with npm

And the example has something like:

const translate = require('google-translate-api');

at the top

That all means it's unforgivably node, right?

Bubbler

It is a Node.js package, yes

Anush

@Bubbler golfing tricks! :)

hyper-neutrino

remove whitespace and comments /s

AviFS

And that in turn means it's totally useless for web js?

Bubbler

Something like webpack can take npm packages and put them into client js files

but the webpack road is a very deep and long rabbit hole

AviFS

06:05

Wait! It looks like this exists?

browserify.org

@Bubbler Oh, this is what you're saying right?

Do you not recommend it? It looks fine at the superficial level

Bubbler

Browserify is an old thing IIRC

I saw people recommend webpack or bower (I haven't seen even bower recently) but they take literally forever to set up correctly...

AviFS

Hmmmm

It might still be the easiest though. The format in google translates post call was ridic

Bubbler

Yeah, I don't think you can mimic the raw request

AviFS

Back to the drawing board!

After all that, you still need a token to send the request.

Your token needs to be given by a google cloud account, and it's not free

So the apis all just have a line with var TOKEN = "your-token-here";

But it should help a lot that I only need to translate individual words

Does anyone have any ideas for dicts to do that with?

Bubbler

06:23

There might be a dict between some common languages if you search hard enough

AviFS

I'm sure there should be...

Bubbler

But really, why do you want single-word translation in the first place?

AviFS

There might also just be low-quality translators, which are high-quality for single words

@Bubbler It's... a thing

I promise I'll share when I have an MVP

Bubbler

"High quality" is absolutely impossible for single words

AviFS

If I keep working on it, it should be within 48 hrs

@Bubbler Well... something like that

In some sense it's easier though because no grammar/sentence structure

That's more what I meant

The precision of translation isn't actually very important for this

Bubbler

06:26

You know, one word can have multiple totally different meanings

AviFS

I know, I know

It shouldn't be that important for the main point of this

And when it starts getting annoying, I can change later

But since you can use synonyms, it won't be too big a deal

Eg. you might not want to search 'duck' in english

Could be n/v

But waterfowl/goose/swan/duckling are plenty close for this
