sure, you could write for i in a: print(i) as i = 0; while i < len(a): print(a[i]); i += 1 but that doesn't make it more correct or pythonic just because it's not as golfy

conciseness is a goal of practical programming too :P they just won't sacrifice readability for it

lyxal

@hyper-neutrino It's a matter of relative conciseness

user

def recursively_print_all_items_in_list_because_i_like_recursion(a):
    if isinstance(a, list) and (a != a[0:0]):
        recursively_print_all_items_in_list_because_i_like_recursion(a[0:len(a)-1]
        print(a[len(a)-1])

@hyper-neutrino Conciseness isn't the primary thing, it's readability. It's just that readability can often be correlated to conciseness (although at some point too much conciseness is bad, which is bad because I would've loved for golfed code to be elegant :( )

wdym?

idk if it even works lol

lyxal

Vyxal equivalent as a lambda: λ:0p≠nLċ∧[n₌tṪx$,|nt,];

And as a named function:

@recursively_print_all_items_in_list_because_i_like_recursion:1|:0p≠nLċ∧[n₌tṪ@recursively_print_all_items_in_list_because_i_like_recursion;$,|nt,];

user

Oh I see what you mean. Try it online! prints each on a separate line (the original had a missing ))

I love how the function name is longer than the body

lyxal

:0p≠ is how you can tell number from list

Note that it doesn't work with strings and lists

@user that do be how golfing languages work

user

@lyxal Wait, why do you need to tell a number from a list?

Exalted Toast

Is there a vanilla sum-of-digits challenge? I can only find variations.

@user because you check for isinstance(a, list) in yours

Redwolf Programs

4:06 AM

It's just occured to me after like 16 years that words like "writing" aren't really verbs in a sense

You always say "I am writing", "I was writing", "You will be writing"

So it's basically an adjective

emanresu A

@RedwolfPrograms "writing" can also be a noun - "my writing"

Redwolf Programs

Yeah, bad example

"crying" might be a better one

"That crying man" and "That man was crying" could both be using it as an adjective

I'd always considered the second to be a verb, but...it sorta isn't I guess

"You cry" makes sense, so "cry" is definitely a verb, but "You crying" does not

Redwolf Programs

Considering renting some servers from Azure or Google Cloud and setting up SOCK² as a paid subscription model. I could make quite a bit of money off that :p

emanresu A

Although... They specify applications - don't you connect through a websocket socks5://...

Or something?

Redwolf Programs

Yeah, it's through a websocket

Indistinguishable from lots of other stuff, but their program might be smart enough to think it's sus if 100% of the traffic is through one IP

emanresu A

Seems unlikely though

Redwolf Programs

Yeah

I haven't used SOCK² in a little while since it takes some hassle to get running, but I suppose I'll do some testing.

If it easily bypasses their new VPN detection stuff, you can bet I'm gonna take advantage of that for profit :p

emanresu A

(I don't know much about networking but) is there any way for them to access the request data sent to your server?

Redwolf Programs

No, it's all HTTPS

emanresu A

Then it should be fine.

@RedwolfPrograms Pro tip: Market it as a "highly advanced VPN" to confuse the IT people even more.

@RedwolfPrograms just two questions: 1) is your Chromebook considered BYOT? and 2) does the computer you use connected to any school wifi?

Yes, and yes

lifewire.com/share-wifi-between-chromebook-and-android-5190435

sure that article is only between chromebook and android, but I'm sure there'd be some sort of workabout

because surely you'd be allowed to get away with having a VPN on a non-BYOT device

How terrible an idea is it to have a code page with no whitespace in it?

lyxal

Depends on the design goals really

Are you okay with not being able to 100% line up with ascii?

And is this for golfing or for just pure esotericness?

Either way, I'd keep at least just normal space unless you have a really good statement separator/NOP

Bubbler

If the code is meant to be human-writable then not having spaces or newlines would be pretty unusual

Otherwise anything goes (e.g. Sledgehammer uses 256 braille chars)

pxeger

@lyxal Jelly isn't ASCII-compatible (it has newline at 0x7F), and afaict that's never been a problem

@pxeger \Will you have an encoded way to include literal strings?

pxeger

11:01 AM

@Adám in terms of having spaces in string literals? That's a good point, but I guess I'll just have some other character that can replace them

@Bubbler the idea is to have a Unicode mode in which whitespace (and all other characters not in the code page, in fact) are ignored, so I was hoping that would be fine
