@NewPosts Perhaps I was overambitious… should I have started by simply asking for a triangular grid of hexagons (ignoring the coloring)?

DLosc

@AkivaWeinberger I think it's fine (and an interesting pattern). You probably won't get a lot of answers, but that's okay--we have plenty of easy challenges, it's nice to get a moderately difficult one sometimes.

Do we think code golf is the most appropriate scoring system for this?

user

That's our most common tag, and the easiest to get right. If you can't think of any other scoring systems, code golf will work just fine

If you do want to use another scoring system, you'll likely have to edit the question (depending on that system). With code-golf, you can just add the code-golf tag and you're all set to go

Q: Minimum Cut finder

Write a program that takes an undirected graph and finds the minimum cut, i.e., the set of edges that, if removed, would disconnect the graph into two or more connected components. The program should have a time complexity of O(n^2m), where n is the number of vertices and m is the number of edges...

@Adám Why does the Dyalog website's favicon have a filled background?

My guess is that it predates transparent background favicons, and that nobody bothered enough to change it.

LDQ: this or self?

emanresu A

oneself

Or we

Adám

@Seggan me

Seggan

actually maybe i could use this for the object and self for the function itself

so i can do cursed things like fun a() { self() }

@Adám serious?

Adám

not really, but you gave no context.

Seggan

19:22

i think you know what i mean :P

for implicit "this object" references inside functions

Adám

Dyalog APL uses ⎕THIS to refer to the current namespace.

Seggan

i.e. java/kotlin this or python/rust self

Adám

and ∇ for the current function, but self would work for that.

Seggan

@Adám yeah... this aint APL :P

emanresu A

Python self is just a convention

Seggan

19:24

yeah ik but its a pretty much unanimous one

Rydwolf Programs

@Seggan this

Adám

me would actually sound kind of cool for example recursive mapping of self, as if the function was speaking.

Rydwolf Programs

Idea: Like it in lambdas, allow that in methods :p

fn add { this + that }

Adám

I've long been wanting ⎕THAT to refer to the last result, like TI-Basic's Ans

mathcat

@emanresuA Add that to the list of things I hate about python :p

I mean, yes, that would give the user some flexibility, but the fact that you have to add "self" as the first argument of every class outweighs it.

Rydwolf Programs

19:36

Worth noting in Rust you still need to specify self as an argument, despite it having special meaning (that's so that you can clarify whether the method mutates the object)

So it's not a Python-only thing to have that annoying self in every method

mathcat

@RydwolfPrograms oof

Rydwolf Programs

IIRC it also means the only thing you need to do to make a method static is just not include a self

mathcat

I'd definitely prefer python's @staticmethod

Rydwolf Programs

Ew

Is that actual syntax

I mean a static keyword maybe, but @staticmethod looks like a complete kludge

mathcat

ig yeah

But so much potential was lost on Python's decorators, IMO they should have made it a major feature.

Rydwolf Programs

20:12

Okay I've just come back to my RTO prototype. Opinions?

Ginger

hmm

Rydwolf Programs

Some things I'm not sure on:
1. Those `CPython:` left-aligned things look kind of odd; maybe no colon would be better?

2. That dropdown on the right doesn't fit, but it seems like it'd be too tall if I tried to make it consistent with the rest of the UI

I also want an "additional options" button thing to bring up a popup where you can change other settings, but that's gonna be a future task

Really those're the only issues I see right now

hyper-neutrino

the cpython/pypy things seem top-aligned with the buttons which looks a bit odd. also about the colons and alignment, have you tried right alignment or do you not like that

Rydwolf Programs

Worse:

It's that weird thing that happens sometimes

I forgot how to fix that, I think I just need to spam some display: flex

hyper-neutrino

you should be able to just make the whole row a flex and do align-items: center in theory

sometimes doesn't work but usually fixes it

Rydwolf Programs

20:18

@hyper-neutrino As in like, everything in the box?

hyper-neutrino

like, right align the category names so the colons line up

Rydwolf Programs

oh right

Looks better I think

@hyper-neutrino This is apparently a <table> so I don't think that'll work

Lemme try

hyper-neutrino

ah. yeah idk how to use tables; i typically avoid them lol

Rydwolf Programs

Oh hang on apparently this is like the one place where vertical-align actually works

Much better

hyper-neutrino

oh nice

Rydwolf Programs

20:26

Do y'all think it'd make sense to have disabled copies of versions present in one variant but not another? So that they line up?

E.g.:

mousetail

why not use display:grid?

Rydwolf Programs

Not familiar with it, and a table works fine

mousetail

It's like half the HTML at the cost of 4 lines of CSS

Plus a lot of extra options

Rydwolf Programs

Are you sure that'd handle things like wrapping right?

And the amount of HTML doesn't matter much when it's all dynamically generated (client side no less)

mousetail

Yes it wraps properly

Table doesn't

Rydwolf Programs

20:35

No, table wraps exactly how I need it to

mousetail

Table doesn't wrap at all

It just looks terrible if your screen is too narrow

Rydwolf Programs

???

It sure does

Grid that

mousetail

Did you do that manually with JS?

Rydwolf Programs

No

Pure CSS

mousetail

Grid works like that by default, I had no idea you could do that with <table>

what does your css look like?

Rydwolf Programs

20:38

I don't know what it is you think I'm doing

My CSS is just this:

#lang table {
    border-spacing: 0;
}

#lang table td {
    border: none;
    padding: 0;
    vertical-align: top;
}

mousetail

But how do you wrap?

hyper-neutrino

presumably all of the options are in one cell

Rydwolf Programs

The buttons just wrap...they're in a flex div

hyper-neutrino

@RydwolfPrograms idt that's a good idea

it implies CPython 1.0.2 exists but isn't supported by RTO

mousetail

Oh you are not using a table for the buttons, just the labels on the left

which don't wrap

mathcat

20:40

^^^ and too much clutter

mousetail

And the buttons are just in a flex box?

Rydwolf Programs

yeah

mousetail

Ah ok, I was talking about the buttons themselves, if you want them to align vertically with the row below you could use grid

Rydwolf Programs

The table's just to make the column of variant names a consistent width, and prevent overflowing from putting them underneath the variant name

@hyper-neutrino That's true I guess

(although the way this is meant to be used, it would imply that. I'm just using made up Python versions, but it's supposed to be the same versioning for the different interpreter options)

I am considering dropping the multiple-variants-in-the-same-language thing tho, and just having different versions, with multiple languages (like Python (CPython), Python (PyPy), etc.)

It does make it more cluttered (and possibly intimidating to someone who isn't sure which Python or which JS they're supposed to use), tho

Rydwolf Programs

20:58

(I mean, I suppose that problem exists for either solution, but with the current one you can have the most recent version of a sensible default interpreter selected)

Rydwolf Programs

21:28

I think I'm just gonna end up writing my own (domain-specific) JS framework lol

The page layout is entirely dynamic (e.g., you don't need compiler args for brainfuck, but you need two sets for a language that transpiles to a compiled language, you use an image upload/editor instead of a text input for non-ascii piet, etc.)

Which makes it very annoying to write with JS's built-in DOM stuff

mousetail

Isn't that exactly what existing frameworks are good at?

Saint Valentine

Saint Valentine (Italian: San Valentino; Latin: Valentinus) was a 3rd-century Roman saint, commemorated in Western Christianity on February 14 and in Eastern Orthodoxy on July 6. From the High Middle Ages, his Saints' Day has been associated with a tradition of courtly love. He is also a patron saint of Terni, epilepsy and beekeepers. Saint Valentine was a clergyman – either a priest or a bishop – in the Roman Empire who ministered to persecuted Christians. He was martyred and his body buried on the Via Flaminia on February 14, which has been observed as the Feast of Saint Valentine (Saint Valentine...

Unrelated String

all of the object's methods are in scope unqualified, you can treat normal functions like they're methods supplying the first argument as the object they're called as methods of, if you call a function with too few arguments it tries a method call with an implicit this argument

Ginger

@UnrelatedString even better: random.choice(filter(lambda i: type(i.__owner__()) == <class object>, locals()))

Unrelated String

therefore the syntax for accessing the current object is... the identity function

for extra cursed points you can also name the default identity function this :P

Entity Component Systems. Data is split into "Components" which store data, and controlled by "Systems" which operate on Components. They are collected as "Entities" which can refer back to the Components and Systems.
