@flawr Ok. So, that set excludes such languages as PHP, Scratch, DOS (batch), Brainf***, sh, bash, tsh, cat, ///...

flawr

Most of those probably can't even process images, do they?

Or at least aren't made for processing images.

wizzwizz4

@flawr So, languages in set(intersection(for_science, for_image_processing))?

flawr

haha, I think for_image_processing is sufficient=)

wizzwizz4

~~That excludes almost everything except Mathematica and similar languages.~~ Ninja'd.

YIL that that dotted line appears above the last message that was posted before you Alt-tabbed away.

flawr

I don't actually know how much mathematica is actually used in sciences.

From the people I know it's actually just some physicists.

@wizzwizz4 Scratch has edge detection

Matthew Roh

What do you think about a massive brawl KotH?

Also I have another idea

Given a passage of natural language, determine its root

Like this:

In this passage, "saw" is the root

So it outputs "saw"

Peter Taylor

Natural language processing is extremely hard. It wouldn't be reasonable to post a question like that without posting about a thousand manually checked test cases.

Matthew Roh

@PeterTaylor Ah. Good point. Maybe limiting the input data might be a good option.

Wait, I just found out there is no SINGLE challenge about cards against humanity

No. Single. Challenge.

Do you know what it means?

SANDBOX TIME!

Maybe the question can be like given an array of black cards and white cards, make a random "passage" with those cards

So if the data is ["How to &arg", "We can agree on more &arg and &arg"],["Drink bleach", "Apple", "Pen"]

Sp3000

16:39

No single challenge doesn't necessarily mean it's a good theme to do a challenge on :P

Matthew Roh

It could output 【How to _】 [Drink Bleach]

:P @Sp3000 I'm doing it anyways since even tho if I dont do it, someone will steal my idea

So I doing it is better

Also on the example above it could also output

【We can agree on more _ and _】[Apple][Pen]

@El'endiaStarman I just wanted to compare it to 3b1b's video, when they actually referenced it: youtube.com/watch?v=skvnj67YGmw

Kritixi Lithos

Are you banned from Scratch? Why?

wizzwizz4

@TrojanByAccident Do you mind if I ask why?

Ninja'd.

They are a little... harsh... when it comes to email addresses.

But I absolutely understand why.

TrojanByAccident

17:15

Yeah

basically, I was talking with someone

we decided that Scratch was not the right place to chat

they suggested google docs

I agreed and set it up

and consequently got banned for "encouraging another user to chat off-site"

wizzwizz4

@TrojanByAccident They've added a new ban message! :-)

TrojanByAccident

And a close friend of mine also got banned, because I let them use my email to confirm their new account, almost 2 years ago

wizzwizz4

@TrojanByAccident :-/

DJMcMayhem

@TrojanByAccident that's one of the stupidest things I've ever heard

wizzwizz4

That's a bit OTT, but I suppose it's to prevent sock-puppeting.

@DJMcMayhem Hey; cut the Scratch Team some slack. It's a kids' site.

They're there to protect them.

TrojanByAccident

@wizzwizz4 Yeah, they're pretty harsh on anyone they think is avoiding a ban

Kritixi Lithos

Idea: break statements in functions, e.g.:

@.each(i -> f(i) ? g(i) : break)

Conor O'Brien

what would it do? stop the iteration of each?

Downgoat

Yes

Conor O'Brien

so, [1, 2, 3].each(i -> i == 2 ? break : (print i)) would print 1 then 2?

Downgoat

19:52

DJ's challenge made me think it could be used like: array.count(i -> i == n ? true : break)

@ConorO'Brien i is the item not the index so you'd have to do i == 3 but yeah

btw you don't need parens around print

Conor O'Brien

@Downgoat right. I miswrote the condition, meant i == 3

@mınxomaτ @Pavel said they preferred having an application instead of a webpage

@TrojanByAccident You still don't, because you can just configure Chrome to open Office files.

docs isn't perfect, but microsoft office is not that good

you should try OpenOffice

mınxomaτ

@TrojanByAccident When I click on an office file it opens Chrome with the appropriate editor. How is that not an "application"?

Pavel

I can't alt tab between it and my internet browsing.

TrojanByAccident

@mınxomaτ Because you aren't using an application designed for editing documents, you're just using part of your browser that happens to be able to do that

I'm not trying to argue that Google Docs is better or worse, just that Chrome can be used a standalone, offline, editor.
