Q: Scan a ragged list

hgl has a "scan" function called sc. What it does in general is a little bit abstract, so we will just talk about one specific way you can use it.

@Adám But that would unnecessarily penalize codebases that have to be enormous, like the Linux kernel

If only we could quantify the complexity of a codebase

Simd

@user just wait until the new APL version

user

It's been here since March

mousetail

@user Tax would be shared between every linux user though so it wouldn't be that bad per person

user

Why the users? Wouldn't it only be shared by the core devs?

mousetail

Shared between every contributor at least

user

4:06 PM

This isn't like the real world, where a company might increase prices to make up for getting taxed

Radvylf Programs

@mousetail Probably weighted by amount written

Simd

@user I mean the new APL version of the linux kernel :)

mousetail

Linux kernel will secretly mine crypo on every linux machine to pay for it's tax

user

Oh no

Then our only refuge will be BSD

mousetail

Is the code size of BSD smaller?

Simd

4:07 PM

:)

Radvylf Programs

What about microkernels

user

@mousetail No, but its so obscure no one will bother taxing it :P

Simd

I like your thinking!

user

I guess it isn't actually obscure

Servers do use it, right?

Radvylf Programs

I say we develop golfkernel™

mousetail

4:07 PM

Microkernels seem the only reasonably option, BSD will suddenly become popular if linux becomes expensive

If only in terms of power use

Simd

@mousetail they have been the future before :)

user

@RadvylfPrograms Written in a golflang and transpiled to C?

mousetail

They have been the future since forever

@user To Rust of course

user

Why would you transpile to Rust?

Radvylf Programs

^

Transpilers don't make typos :p

user

4:09 PM

Rust's borrow checker is useful if you're using it directly. Compiling to it makes it useless

@RadvylfPrograms They do when I write them :P

Radvylf Programs

Although I guess why transpile to C either, just use LLVM or whatever

user

True

Transpiling to C may be easier for some languages though

mousetail

Do you want manual memory management in your golfing language though?

user

Who said anything about memory management?

Let the garbage pile up :P

mousetail

I think rust-style borrow checker with maybe some kind of auto boxing system might be golfiest

auto clone, auto copy

user

4:13 PM

When the program ends, the memory gets freed. No need to worry until then :P

You could also use the type system to avoid cycles and then use refcounting

Radvylf Programs

@mousetail The transpiler'd handle that

user

Closures would be tricky but still doable

Radvylf Programs

And Rust isn't garbage collected anyway, you'd still need memory management

mousetail

If it's a microkernel we could just periodically restart modules to free their memory

user

And instead of defragmentation you just completely reinstall the entire system every once in a while

Radvylf Programs

4:15 PM

Let's just require that freeing unused memory is a module

The kernel wouldn't worry about it

user

And use something like the Boehm GC?

Radvylf Programs

4:27 PM

That or defragment the RAM and inject code into the kernel to fix the pointers so they point to the new locations

Mumble mumble virtual memory mumble

user

There's a stupid but easy-to-implement GC where you only use half your memory at any one point, and when you start running out of space, you stop everything, copy everything over to the other half of your memory, and start again, leaving the dead objects behind in the old half

Radvylf Programs

Couldn't you use all of your RAM and use xor-swapping instead of copying

user

CMQ: What is the most cursed approach to garbage collection? (not doing GC at all and letting the garbage pile up doesn't count)

@RadvylfPrograms What's xor-swapping?

Radvylf Programs

@user All of your RAM is a linked list; to access the pointer 0x12ab, you follow the linked list to that index. Any time you free up RAM, it's a linked list, who cares

@user Just a way to swap two values without using a temporary value

You'd just copy the second half of RAM into the first, using swaps, then you'd have the first half of RAM on the right, out of order, which you'd reorganize

mousetail

@user Inverse reference counting. If the amount of objects that do not use yours equals the total number of objects, delete it

Radvylf Programs

4:37 PM

@RadvylfPrograms (this is actually how I implemented RAM/GC in a brainfuck-based virtual machine I made where performance didn't matter)

mousetail

@user "Scream test" reference counting. Copy the entire state of RAM. Then delete a random object. Then run the code. If it errors, the object was important. Restore RAM and try a different object.

user

That's absolutely beautiful

What about user input that's been passed before it errored, though?

mousetail

Add it to a queue somewhere so it can be multiplexed to the new iteration

If your memory runs out again though you overwrite the snapshot so better hope that object is used in the meantime or it's gone foevever

Ginger

4:52 PM

@RadvylfPrograms smallest possible kernel that can run a Linux-built program, actually not a bad idea :p

caird coinheringaahing

@user Don't collect the garbage, reallocate it to memory being used by the program

Ginger

@user Easy: When RAM is getting full, write the entire thing to disk, clear RAM, and load in every possible combination of objects in order until the program doesn't crash

Or, when RAM is getting full start writing objects to disk, oldest ones first, and retrieve them if they're requested

mousetail

@Ginger That's just swap though

Already how it works

caird coinheringaahing

@user As soon as RAM starts to get full, just wipe the entire computer's memory

Ginger

OOH I JUST HAD AN AWFUL IDEA ONE SECOND

Okay hear me out: Paper Swap

When RAM fills up the computer starts printing memory on actual paper using a printer, one RAM page per physical sheet, and when it needs a page you have to put that sheet of paper on the scanner to load it back in

probably using some kind of matrix data representation or smth

mousetail

5:02 PM

What about as punch cards?

Ginger

also, just broke 6k site-wide rep!

mousetail

Congrats

Ginger

@mousetail you can't really print those, and I like how paper pages can work as physical pages

mousetail

True

Ginger

this is a godawful idea and I'm trying to resist implementing it

mousetail

5:03 PM

There are specialized devices that can "print" punch cards

Ginger

I don't own one (also punch cards have lower data storage than paper)

mousetail

@Ginger It would be quite a lot of effort, I'd like to see it in action

True

How big is a "page" of RAM?

Ginger

depends

quick someone find that guy that made a paper on bad swap ideas

mousetail

Like killobytes, megabytes, gigabytes?

So 1 MB

Ginger

wait no one second

according to Wikipedia the smallest possible page size for a 64-bit processor is 4KiB

mousetail

5:05 PM

Oh that's reasonable

You could fit that base64 encoded in a smallish font on A4

Ginger

that's 4096 bytes, or 32768 bits

@mousetail no, this idea would use a matrix-barcode-type-thing for easy readability

mousetail

That would make it even easier

You could even use color for extra depth

Ginger

okay, a Data Matrix code can store 1556 bits of data, so one page would only require a miniscule 22 of them! :p

each code is 144px square

2480 x 3508 at 300 ppi

hmmm

mousetail

Quite a lot in theory but scanners are typically terrible

Ginger

yeah lol

Hannah Williams

oof

mousetail

You probably want a lot of redundancy so if the scanner just overexposes one corner for no reason you can still read what it says

Ginger

so what's the best way to fit 22 144x144 squares onto an A4 sheet of paper?

they can store 1556 bits, but we'll store 1024 of data per code and have the rest be metadata

@mathcat what

oh, adam

caird coinheringaahing

@Adám Given that the answer is basically "all", I don't think it's necessary

I think we were the last "big" site in the network to get ChatGPT posts

Ginger

> "big"

caird coinheringaahing

We have multiple questions on the HNQ at any given time, and have decent engagement stats compared to a lot of the ~180 sites on the network

Tho, we have been on a downswing lately, we used to be at around 1k visits/day

Adám

6:32 PM

@cairdcoinheringaahing But maybe having a list that quickly grows to over a hundred would make them reconsider?

Radvylf Programs

@UndoneStudios It would mostly be symbolic

Adám

if /s is for sarcasm and /jk for jokes, how about /se for dispair?

Radvylf Programs

But it would come with things like a link in the room description, maybe an official meta announcement, and probably would be officially RO'd by the TNB RO team instead of just de facto RO'd by them

caird coinheringaahing

@Adám I doubt very much they'll reconsider

Adám

Hence "/se"

caird coinheringaahing

6:34 PM

The official policy is "We'll leave it up to the sites", which is a good call IMO

Note that the posts here that were suspected of being ChatGPT weren't deleted for that reason, they were deleted for being low-quality and for not answering the challenges they answered.

Seggan

why dont we ban chatgpt?

because then when it becomes sentient we all die

On DIY or Cooking a bad ChatGPT answer could cause someone to electrocute their cat or get botulism. On CGCC it's just another non-working post, no harm.

Adám

Is GitHub Copilot only trained on GitHub-hosted code or also on code from, say, SO?

mathcat

Radvylf Programs

Banning ChatGPT on those sites reduces the amount of work; if it's ChatGPT, delete. On our site, it's pretty much an equal amount of work to check if it works or if it's ChatGPT.

DLosc

7:23 PM

@RadvylfPrograms The other concern I've seen mentioned elsewhere is that ChatGPT answers should say they're generated by ChatGPT, in order to follow correct attribution practices.

On CGCC, I think there's been a general policy of "if you didn't write it, you should make it community wiki"--I wonder if that applies to ChatGPT?

emanresu A

@DLosc That's explicitly not the case

There's a relevant meta somewhere

caird coinheringaahing

If you didn't create the post/code, you must provide attribution. It's recommended you post as CW, but not required

Radvylf Programs

@DLosc Funnily enough I was actually just discussing the question of ChatGPT and attribution with my AP Research teacher (in the context of education)

My position is that GPT and other AI text/art programs should basically count as people in terms of attribution, both for training and for using their output

@emanresuA a very small subset at that

@cairdcoinheringaahing That's actually correct J code for the given problem. And Jelly is inspired by J, so…

I'd imagine not much literature about Vyxal got included in the training dataset

emanresu A

With copilot, it picked it up while I was writing unit tests

Adám

@cairdcoinheringaahing Why do people tend to post screenshots of ChatGPT instead of quoting in text?

caird coinheringaahing

For the code section ones, it's a bit hard to do

lyxal

@Adám because the copy paste support is really bad

You try and select the conversation but then it goes and includes things like your email and the time of each message

Which aren't visible when talking to it but are there on the page

Meaning you need to take time to edit those out while a screenshot is just easier

@emanresuA only when it has context

@emanresuA of course it will - it has lots of other data in the file to learn from

And it'll only know it in that context too

emanresu A

10:49 PM

Good point

lyxal

even then, it doesn't actually "know" Vyxal or Jelly or any other language it purports to know. It simply writes stuff that it thinks should be statistically completed based on what it's been fed. It may look like it "understands" code snippets, but it's simply the most appropriate/probable token generation from the tokens you give it

Unrelated String

i think the real distinction here is that it doesn't approximate a systematic rules-based understanding of them, just the end results
