@DialFrost ah. this looks good, just make sure it isn't a dupe

okey ill go check

@DialFrost split by spaces?

er u may assume the text has spaces in it

ill change it so no punctation is allowed either

upper+lowercase allowed

Aaroneous Miller

@DialFrost Wouldn't it be "The quick brown fox jumps the dog"?

erm im still working on tat

cuz the dog has a punction with it

punctuation

so its length is 4

actually shld i add punctuation to test cases

make it more intersting

@mathcat drat, foiled again

ta Radvylf srik su shilani

Any feedback on Inject arbitrary code into a compiler?

@AaroneousMiller Just a warning, I don't know if Vyxal would qualify for this CnR

Due to the requirements about the language being deterministic

And it also specifies the cop should make the language, so you'd probably just have to make a version of "vyxal" with the subset of features required for the ACE

Aaroneous Miller

@taRadvylfsriksushilani Vyxal has some commands for RNG, but other than that it's completely deterministic, to the best of my knowledge

@taRadvylfsriksushilani I helped make Vyxal

ta Radvylf srik su shilani

Hmm, I guess that'd count.

Aaroneous Miller

If you don't think it qualifies that's fine, I'll leave it up to you

ta Radvylf srik su shilani

2:40 PM

It's a bit of an exception under the current rules I guess, but excluding an ACE in vyxal wouldn't be very fun

Just like...answer in "Vyxal but don't use the RNG operators" and I'll be fine with it :p

Aaroneous Miller

like the Float.pow function in kotlin, in normal cases, which the pow function is not a part of since it is an extension function, you do it by doing, kotlin.math.abs for instance, should import directives be compulsory for code golf submissions?

Challenge idea: Given a grid filled with + and slope change all the plusses, whose center is above the line y=mx as an x.
Considering the width and height of the plus as a unit, and O is the bottom-left corner.
Example:

Input:

2

Output:
xx+++
xx+++
x++++
x++++

Um, I have a python problem.

@mathcat what is it?

Given a nested list like [1, [2, 3], [4]]

Ginger Industries

@mathcat don't we all

can you get an item, by passing the list's indices as a list?

Ginger Industries

what

3:56 PM

@mathcat i don't understand

e.g. list.function([1, 0]) would give 3

like list[1][0]

oh, I will solve

me too

lambda f:f[x[0]][x[1]]

no

the list is ragged

it's depth could be more than 2

3:58 PM

I will solve, but i'm lazy

def function(lst, indexes):
    return eval(f"lst{''.join(map(lambda x:'[' + str(x) + ']', indexes))}")

@BgilMidol wrong

why?

Aaroneous Miller

@mathcat shouldn't list[1][0] give 2 for that example?

oh yeah

4:02 PM

lambda f,x:__import__("mathcat").senitro("do the recent task").(f, x)

lol

@BgilMidol gives an error to me

@mathcat what error?

sudo bestpip install mathcat

Int is not subscriptable

4:04 PM

?

oh working

thanks

it's hacky though

for now it's okay I think

Aaroneous Miller

4:17 PM

@mathcat Try it online!

nice, but can I also set arr [some pos] to something?

@mathcat try f = lambda x, y: x[y[0]] if len(y) == 1 else f(x[y[0]], y[1:])

noice, but I need to be able to set something at that position

def function(lst, indexes, setval):

Ginger Industries

Fortunately, the charging one has been solved now that we've all standardized on mini-USB. Or is it micro-USB? Shit.

ta Radvylf srik su shilani

Windows: Most common, but kinda sucks in a lot of ways
MacOS: Pricy hardware and lacks some freedom
Linux: Not evil but very ugly and lacks compatibility with lots of stuff
Chrome OS: Only good for cheap laptops
iOS/Android: I'm not writing code on a screen that tiny

If only we had a small, secure, nice looking OS with extremely good hardware and application support

@taRadvylfsriksushilani phones boot quickly (well they never shut down

ta Radvylf srik su shilani

But we can't even manage to get good support for linux after decades

@user I only gave them gray since when you do shut them down or update them, it's kinda inconvenient

Because no corporation owns it and there’s a million distros

Ginger Industries

4:32 PM

@taRadvylfsriksushilani so you want Linux but it can run Windows apps?

@taRadvylfsriksushilani isn’t chrome os the same once you shut down?

Ginger Industries

@user I'm sorry once you what

@GingerIndustries i think they want more appa for linux

@GingerIndustries shut

ta Radvylf srik su shilani

Linux needs something like a Microsoft, that runs it on hundreds and hundreds of computers and makes sure any compatibility issues are fixed, and keeps graphic designers on salary so they can make it look good

Ubuntu kinda like that

ta Radvylf srik su shilani

4:33 PM

But they're too Microsoft

And Ubuntu still manages to be ugly and have bad compatibility

But people are just so used to mac and windows and linux doesn’t advertise

ta Radvylf srik su shilani

@user Chromebooks boot up almost instantly

@taRadvylfsriksushilani because they’re not enough like microsoft (not that being a big bad corp is good)

@taRadvylfsriksushilani mine takes half a minute :(

Ginger Industries

@taRadvylfsriksushilani ubuntu gets closest to what you want

ta Radvylf srik su shilani

@user And yet they already do the bad-Microsoft-things, like centering things around profit too much

We need an OS made by a non-profit company

Ginger Industries

4:35 PM

@taRadvylfsriksushilani well do you have any suggestions?

What do you expect them to do? Profit is why they exist

ta Radvylf srik su shilani

That can take care of advertising and testing and UI/UX, but that doesn't have to be overly bad

@taRadvylfsriksushilani yes

Ginger Industries

y'know actually

we're kinda in an Alexander Graham Bell-type situation here

Remember that Non profits aren’t always good tho

ta Radvylf srik su shilani

4:36 PM

cough cough collegeboard

My mom volunteered at one and the head gave herself and her right hand huge salaries

Ginger Industries

we've got all the parts for a good-looking, well-built Linux-based distro but we just haven't put it together

@taRadvylfsriksushilani :(

ta Radvylf srik su shilani

Windows feels kind of...idk, bloated. An OS should be kinda small IMO. It's the base that your apps run on, not the whole entire computer.

@GingerIndustries good looking distros exist already

ta Radvylf srik su shilani

4:36 PM

I kinda think we should start from scratch honestly

Windows and Linux both have decades of compatibility stuff they have to deal with, and have security and other issues that can never be resolved, ever

@taRadvylfsriksushilani what? No don’t take away my preinstalled microsoft todo and solitaire what would i do without them /s

@taRadvylfsriksushilani have you considered that this is hard

Ginger Industries

Lots of applications? flatpak/snapcraft + some sort of APT gui
Good design? plenty of desktops to choose from
Price? Free
Just works? this is the hard part but I think it can be done

ta Radvylf srik su shilani

@user Yes

Any software will get compat issues eventually anyway, best to stick to linux

@taRadvylfsriksushilani like really hard

Ginger Industries

@taRadvylfsriksushilani these are kinda unavoidable consequences of making an OS

ta Radvylf srik su shilani

4:38 PM

I disagree

Ginger Industries

methinks it's about as good as it's gonna get

^

ta Radvylf srik su shilani

Unfortunately, for practical reasons, I do too

I’m hopeful about linux support getting better but it probably won’t change much

ta Radvylf srik su shilani

Linux has massive compat issues despite existing for decades, so anything new is virtually guaranteed to fail unless all of the major companies were backing it and there was enormous incentive for app developers to port things to it

4:40 PM

Also the boot time isn’t a huge issue imo, but small linuxes exist already

ta Radvylf srik su shilani

I don't want things to be small for boot time reasons, but for security and simplicity reasons

Security?

ta Radvylf srik su shilani

Yes. The less code, the fewer bugs can hide in it.

Ah

ta Radvylf srik su shilani

Bloated, rarely used features are more likely to see less scrutiny and harbor really bad vulnerabilities

4:41 PM

How many issues does unix have compared to linux?

ta Radvylf srik su shilani

Unix?

Does that still exist?

I’m sure someone’s got an os that’s close

ta Radvylf srik su shilani

BSD is close to Unix I think

MacOs?

ta Radvylf srik su shilani

That's based on Unix too yeah

But I'm p. sure it's not that similar

4:43 PM

@taRadvylfsriksushilani specifically bsd right?

ta Radvylf srik su shilani

No idea

Not a fan of macos, if bsd’s like that, then imma be sad

metasmoke.erwaysoftware.com/posts why a lot of Help Microsoft talk to a person?

because microsoft impersonation scams are very popular because most people who aren't that tech savvy use windows and it's also much easier to attack

also i think it's also just the most popular OS even ignoring how likely the person is to fall for the scam so it makes sense to attack that OS
