And now we can put 4k in a 13" laptop

(Which by the way, even as someone who loves really stupidly high pixel densities, that's stupid. There is literally no upside.)

Unrelated String

yep lmao

(It's the only way to fit in enough subliminal advertising.)

This seems like a really dumb question, but

If something gets "compiled to java bytecode", I'm assuming e.g. a Java program compiles code to java bytecode, not that the compiler is written in java bytecode itself.

Yes

How would that be faster than directly compiling the code to java, which is compiled to bytecode by the java compiler?

That greatly depends how similar your language is to Java

If it is very different there might not always be a convenient Java equivalent syntax, requiring a ton of code to emulate simple things. While in bytecode this might just be a handfull of instructions

Q: Remove a given substring 'n' number of times from the end of a string

The user inputs a string and a substring. It also input a positive integer 'n'. Remove the 'n' duplicates of substring from the end of the string. If the substring is not present in the string or the number of times the substring appear is less than 'n', then the output is the original string. No...

ah

7:10 AM

I've never heard of anything that compiles to java source code, while I have for C and java bytecode

So that means if I write a language in java, it's not necessarily slower than compiling it to bytecode?

I mean you need to parse every intruction instead of just executing it

A compiled language, not nececairly

Kotlin exists, it's not slower as far as I'm aware

hmm, conda update is trying to install jellyfish

-> (()=>tar((,))())()

eval("eval()")

12:11 PM

@Ginger ... but that's the most useful part of Firefox

what kinda firefox yall got in britain

12:27 PM

just learned about Python f-strings and all I can say is how tf did I not know about these earlier

I will never use another string-replacement method again

I've not used anything except f strings for years

It's good for golfing too, str(x) vs f"{x}"

ooh, clever

Especially when cocatenating multiple things, like str(a)+str(b) vs f"{a}{b}"

anyone here use OS X? I have done "brew install texstudio" but I don't know how to run texstudio now it is installed!

Feeling very dim

Simple: Use Debian instead and install it from apt /s

12:37 PM

@Ginger hmm... :)

which *.se should I use to ask this stupid question?

Ask Different

Won't ./texstudio work?

Or without the ./

@mousetail sadly it can't find it

Very sad. Lets observe a moment of silence

that's not going to help me!

:(

12:48 PM

neither of us use Mac I think

py3_and_c_programmer

@DialFrost seems like people don't like :3 ig

:(

@Ginger windows is life

I have spent my life on linux

imagine not using linux

but the only computer here is an OS X machine

so you don't have a choice?

12:49 PM

exactly

okay, good

I was a bit worried for a second there :p

:)

py3_and_c_programmer

the prequel to the current OS in apple is um... NeXT's kernel right?

or something like that

why does the room get quiet when i message

because we don't have anything to say

py3_and_c_programmer

Well i see

12:54 PM

From the chattiquette:

py3_and_c_programmer

bet none are researching right now

> Sometimes, there isn't anybody talking in chat. That's perfectly fine. Don't send messages just because the room is quiet.

py3_and_c_programmer

thats the second time somebody sent me this now

... maybe it's time to read it then

That message really shouldn't be starred since it's slightly rude

^

12:57 PM

would you like the star removed?

I would

py3_and_c_programmer

i would

done

TY

first time I've gotten to click the "cancel stars" button on a post here :p

12:59 PM

So you consider your message slightly rude but also consider that the problem is the person starring it and not you writing it?

py3_and_c_programmer

Is anyone reviewing this rn: codegolf.stackexchange.com/questions/253732/…

@Fatalize I mean there is a difference between pointing something out at the moment and drawing attention to it for days

a = "eval()"
a = "eval(" + a + ")"

if only it worked that way

py3_and_c_programmer

~~Actually, it doesn't~~

~~escape sequences are so tiresome~~

~~which is why I use ' instead of \"~~

no sequences need to be escaped there

py3_and_c_programmer

1:07 PM

My bad, the thing is that I just get so used to ~~escaping~~ " so much that for code-golf reasons, I switched

to using '

But ' escaping is exactly the same as " escaping

py3_and_c_programmer

as in, "We are the \"Vikings\" from the north" = "We are the 'Vikings' from the north"

'We are the \'Vikings\' of the north' vs "We are the 'vikings' of the north"

Especially usefull with contractions

"This won't hurt" vs 'this won\'t hurt"

py3_and_c_programmer

@mousetail don't you recognise the source?

I do not, sorry

py3_and_c_programmer

1:13 PM

w3schools.com/python/python_strings_escape.asp

Scroll through the entire thing

Yes

If a string contains single quotes PEP8 recomends surrounding it with double quotes, else if it contains double quotes suround it with single quotes

py3_and_c_programmer

I used w3schools for learning c

w3schoolds is kinda terrible though

They produced this gem: w3schools.com/howto/howto_js_sort_table.asp

MY EYES

py3_and_c_programmer

@mousetail I totally disagree

1:15 PM

This would be a good submission to code-trolling yet it's a example for students

To think people actually copied this code to their website

The quotes example is also a good example of w3schoold being terrible actually, since it somehow implies that single quotes require less escaping even though they work the same

py3_and_c_programmer

What would you recommend them to change it as?

Cite PEP8 and include some examples for both single and double quoted strings

Also explain what hex and oct values are

py3_and_c_programmer

why?

The escape codes are not really explained at all

What use is a list of escape codes if they have vague descriptions? Might as well not include them

It can link to a page about character encoding/unicode maybe. A link is good no full explanation needed

py3_and_c_programmer

im out

1:31 PM

one day an OS X user will be in this chat room

Don't hold your breath

I highly doubt it :p

so prejudiced! :)

Can't you ask in one of the askDifferent chat rooms?

ninja'd

1:32 PM

this is the only working chatroom in the world.. but I'll try

ooh, they don't have very many rooms

@graffe What a honor

their main room is currently completely empty

@mousetail yes! And deserved

For chat rooms it's quality over quantity

1:32 PM

@Ginger cough... my point exactly

I have an idea, just a second

k....

What if we invite someone from Ask Different into this room? they'll get notified so they're sure to see it

You just said there was nobody in that room though

alternately, you can ping someone in the ask different room

I think that'd work better

1:35 PM

That seems 1000% easier

Does the "ping everyone" hack still work?

nope, the user I had in mind hasn't logged on for long enough that they're unpingable

Wow Apple really is dead

I guess the USB-C thing hit them harder than expected

lmao

I tell you, this is the only working chatroom left on the planet

TNB is one of if not the most active SE chatroom

...that's a weird sentence

I actually have to think about parsing it

1:38 PM

There's plenty of discords I'm chatting in right now though

it made sense to me

@mousetail I never found a useful discord

@mousetail discord is a different beast entirely

@graffe What about this one? discord.gg/VtXcQawp

can you explain it to me. I think I don't get it

Explain what?

1:40 PM

@mousetail discord

it's just chatting just like here, except you can add reactions under messages

*burn*

I can never log into it. It is now saying I already have the email address but I don't know the password. I used a different address and it wants an administrator password to install the app.

is there an OS X channel on discord?

There are literally millions of discord servers

Not like here where there are a few about specific topics

well I can't log in to any of them :)

1:44 PM

@graffe There probably even is one about Harry Potters's left toenail.

I can 100% guarentee it

Not really because discord but because Harry Potter fans are totally insane

can confirm, unfortunately (the insane part not the toenail part)

ಠ_ಠ

ok one step towards running texstudio taken

I have found it but it says "“texstudio” cannot be opened because the developer cannot be verified."

f

1:46 PM

Can't you just ignore that?

not sure there's anything you can do about that

Windows always warns me about every single program but you can just click ignore

Imagine using Mac or Windows lol

@mousetail it won't run at all currently

ok cracked it

what a pain

the secret is to ctrl click the icon for texstudio and then choose open

who knew

amazingly apple.se gave a useful answer

2:18 PM

Why was this edit approved? It singificantly changes the rules of the post: codegolf.stackexchange.com/review/suggested-edits/66566

good question

Also I'm not convinced formatting the whole test cases section as code improves readabiltiy

2:44 PM

remind me: if you draw a card in Uno do you have to keep drawing until you get a playable one?

wikipedia doesn't seem to say

Depends on house rules

hmmm

should Schrodinger's Uno do that?

I'm going to go with yes

3:48 PM

I just got a suggested edit for one of my Pip answers, changing the ATO link to a DSO link (since ATO's Pip interpreter is currently broken). Not sure how I feel about that. On the one hand, it's true that DSO currently works and ATO doesn't. On the other hand, I expect ATO will be fixed at some point in the future, so is it really a necessary edit? What do y'all think?

Update: Schrodinger's Uno is rapidly becoming one of the most complex projects I've ever made

should we add a feed for new AoCG sandbox posts?

No

It's pretty easy to keep track of new ones, there's at most 25

1 hour later…

5:32 PM

I think I have just written the worst piece of code of my life

was it written in rust

no, it's python

here it is: gist.github.com/GingerIndustries/…

that function is responsible for dynamically making the image that the Schrodinger's Uno bot sends to the players

it's full of garbage but I think the worst offender is line 17:

im.paste(card.image.resize((128, 256)), (((c % 7) * 128), (((c // 7) * 260) + 25)))

that's like 7 magic constants in one single line

Code Review would have a seizure if they saw this

6:00 PM

why so many unnecessary parentheses

honestly you can remove most of them

6:28 PM

order of operations has bitten me in the ass many times before

I'm making sure it never will again

Radvylf Programs

Yeah I would consider parentheses around *//////% operations reasonable, since treating them as left-to-right and the same precedence isn't super natural

around what operations

Radvylf Programs

user image

you must have some userscript installed

Radvylf Programs

I do

Chat Monospace Fix

Mar 21 at 17:17, by Radvylf Programs

@Ginger Do you not have chat monospace fix?

We've discussed this before :p

6:31 PM

it just looks like *//////% to me (which I believe is ASCII C syntax for the bitwise norxor gorgondax)

@RadvylfPrograms I would if I could :b

im.paste(card.image.resize((128, 256)), (c % 7 * 128, c // 7 * 260 + 25))

to me it looks fine and clear :P

Hello :) Just a quick Python question. To get a submatrix (in my toycode, getting a "box" from a sudoku board), I can get the first box by running sudoku_board[np.ix_([0, 1, 2], [0, 1, 2])]. Is there a way to do this without having to explicitly note all columns (0,1,2)? I'm thinking in a notation like 0:3

hmmmmmmmm

I mean you could use list(range(2)) but I don't think that's what you want :p

@ihavenoidea does 0:3 not work?

@Ginger 3* :P

ffs

6:46 PM

Unless I did something wrong, it doesn't work with np.ix_(). If I do sudoku_board[0:3] or sudoku_board[0:3][0:3] it gives me the first three lines (all of it, not capped until the third column)

dunno then, I don't use numpy very much

Thanks!

I didn't really do anything but ok no problem I guess :b

gave me your time, that's more than enough xD

oh, got it

np, anytime!

6:52 PM

> numpy, anytime!

oh no

7:16 PM

sudoku_board[0:3, 0:3] does what I want, derp

nice

was using your range suggestion, but it was bothering me lol

ok who wants to play Schrodinger's Uno?

I'm pretty sure I got it working

8:40 PM

cc @emanresuA

@Ginger whaz that

like quantum chess?

@Sʨɠɠan it's a chatbot that lets you play Uno against other users

I call it Schrodinger's Uno because it uses magic trickery to show each player their hand using only one image

do you want to play?

i might not have time?

doing school rn

understandable

a game usually takes 5-ish minutes and as long as you don't leave chat you can take as long as you want on your turn

fine ill just hide this tab behind my giant circle of dead pixels

8:51 PM

u wot

(also the bot is in the sandbox)

@Ginger i conveniently have a giant circle of dead pixels right on top of the reload button

so if i pin this tab i can hide it
