@pxeger I genuinely don't know whether it's "mold" or "mould". Cause, the second one is a word for me (first isn't), but every time I've seen Dennis use it, he calls it "mold" (and I think that's what it's called in the docs)

@Dudecoinheringaahing look at the credits :)

Dude coinheringaahing

@PyGamer0 Ha, nice :P

That might explain the upvote I got on that answer earlier :P

@Dudecoinheringaahing yes that does

@PyGamer0 wow you port jelly to python? Lame.

@exedraj lol

12:12 PM

Real gamers just straight up copy paste jelly source code into their language

Attributing it properly of course :p

Dude coinheringaahing

@PyGamer0 One thing to note: I wouldn't use fillvalue. For example, if f is product, that will zero out the extra elements. A better approach is to use zip, then do + x[:len(y)] + y[:len(x)], which leaves trailing elements untouched

@exedraj might as well copy +

@Dudecoinheringaahing I'd argue that's useful behaviour

@Dudecoinheringaahing Both spellings are correct for both mildew and shaping.

@Dudecoinheringaahing so zip(x, y) + x[:len(y)] + y[:len(x)]?

Dude coinheringaahing

12:15 PM

@PyGamer0 [function for x, y in zip(x, y)] + x[:len(y)] etc.

@Dudecoinheringaahing oh ok

Dude coinheringaahing

zip truncates to the shortest, you then append the extra elements that were truncated

@exedraj But what about for other builtins?

Using fillvalue = 0 might be good for some, but it will inevitably lead to some weird edge cases that'll be annoying to handle

@Dudecoinheringaahing ok updated

@Dudecoinheringaahing duplicate and mild, no?

Dude coinheringaahing

@exedraj That won't always work. For example, one way to replace the first 2 elements of a list in Jelly with a given pair is o (or ḷ") because the vectorisation only considers the first 2 elements

Moulding would replace the entire list with those 2

CMC: Given an integer and a list, add that integer to only the first element of the list

@emanresuA You passed me in reputation D:

@Dudecoinheringaahing I meant, given the existence of "jelly molds/moulds" (things that hold jelly into shape while it solidifies), did Dennis choose the word mold/mould to make a pun deliberately?

Dude coinheringaahing

@pxeger I doubt it :P

@CodidactPosts Ooh, a nice 2 byter in Jelly :P

@BrowncatPrograms did you ever do the pacer test to the fitnessgram audio?

Browncat Programs

In elementary school, yes

Not in middle achool too?

Browncat Programs

Nope, not in middle school.

Lucky

12:38 PM

achool sounds like a place to learn to sneeze

Browncat Programs

I think schools have the choice between that and running a mile

In 6th grade we probably just ran a mile, and I know for certain that in 7th and 8th I did that because I was in track :p

We had to do all of them and planks :(

(I ask because my meme taste has descended down a really weird path tonight)

Browncat Programs

In 5th grade I actually did better than everyone else in my class at push-ups and sit-ups, which is...suprising

I am very good at sitting up

12:41 PM

mandatory exercise sounds like a very good idea and I want to know why UK schools don't do it

Lazy brits

maybe it's because it would be literally nineteen eighty-four

@pxeger huh? uk schools have PE

I'd consider that separate

Browncat Programs

Exercising in PE/gym being required? That's a terrifying overstepping of the government's boundaries :p

@pxeger Where do you think we did those things :p

12:42 PM

fair enough

Is this not running a daily mile? For all children, every day? Maybe I've misunderstood lol

Browncat Programs

What now lol

doesn't seem that separate to me, then again I haven't done PE in about a decade so who knows :P

we mainly did skills-type things in PE, so most of the time we weren't doing exercise

maybe that was just me though lmao

Browncat Programs

@pxeger It's an annual thing

I love how "How are you?" "Hi!" "Good!" is an exchange which I've seen happen at least monthly :p

Also someone just nearly walked into me, so I stepped out of the way, then they glared at me

1:30 PM

wow redwolf how could you be so rude as to avoid crashing into someone?

gosh, no manners. smh. /s

Browncat Programs

Maybe they think this is like one of those .io games where if you crash into someone smaller you absorb them and become bigger

well who was the bigger one?

you or this stranger?

@exedraj I YAMLn't

@AaronMiller well now is a good time for you to YAML

Browncat Programs

I was taller, but probably smaller overall

Three dimensions makes it more complicated

1:33 PM

overall?

@exedraj ok

there's height, width and depth

@BrowncatPrograms so you win in height, how about width and depth?

Browncat Programs

Probably lost both of those

hence, they're bigger

because it's best of 3

Browncat Programs

Ah ok

1:34 PM

see that's why they glared at you

they were personally offended that you wouldn't be generous enough to let them absorb you

@exedraj The real question is, do you win in the fourth dimension?

Browncat Programs

So in order to win, I need to find someone short and thin, but they can be very deep. Or someone short and shallow, but they can be wide.

@BrowncatPrograms correct

@AaronMiller I mean, probably

because, y'know, the whole entire "raiding civilization on and off since the dawn of time" implies a lot of time has been yes

Browncat Programs

Today I learned there's a zero width non joiner, in addition to the zero width joiner

Yeah? Well today I ate lasagne

Beat that.

1:41 PM

Today I'm having jambalaya for lunch.

Browncat Programs

Today I'm having a soggy hamburger and fat-and-sugar-and-salt-free french fries for lunch :p

Lame.

I always get unreasonably happy when people use "touche" properly in normal conversation.

Dude coinheringaahing

1:43 PM

so, just french?

@Dudecoinheringaahing yes

not chat, evidently

Dude coinheringaahing

huh

@pxeger ah yes I do love eating the French

Browncat Programs

It's basically just potatoes soaked in water and put in a frying pan from what I can tell

Dude coinheringaahing

Yes

1:57 PM

@pxeger So in principle one could create a static clone site.

Dude coinheringaahing

@rustyx the API is still working, so you could use one of the apps (if you still have them installed, that is ...) — Glorfindel ♦ 3 mins ago

we should just suspend Community

oop. Now the site is actually down.

2:04 PM

I'm sorry community. I didn't mean to be mean to you like that. :(

Maybe SE got DDoS'ed by all the devs leaning on F5?

It probably has to do with fixing whatever was broken, would be my uninformed guess.

I thought the ECB was the European Cardboard Bank

@pxeger I'm not really sure what it means for them to not be legal tender. Are they saying it cannot be exchanged for €0 worth of goods?

Dude coinheringaahing

Legal tender means that it must be accepted in order to settle a debt, not that it can be

Credit cards aren't legal tender

2:59 PM

Why was it even made in the first place?

To make money, of course.

I assumed it meant you can pay for a €5 item with a €5 note, but you can also pay with €5+€0 notes

But seriously, the only reason to make these is to make money of fools.

how hard can it be to yeet out the 2nd element of a list ;_;

that flipped reverse scan is sooo nice

how did you come up with it?

if you remember this whole triangle idea:

1
0 1 1
1 0 0 1
0 1 1 0 1
…

I realized that the next row is always like, (a bunch of ones) - (the last row). so to get the next row from [0 1 1 0 1] you can subtract it from [1 1 1 1 1 1], and get [1 0 0 1 0 1].

3:49 PM

ahh, yeah, nice

but, if you apply the dot products to that explanation, you're just doing (next cumsum) - (current element)

so, the next element from b+c+e is: sum[a..f]-(b+c+e) = a+d+f

Why do bitwise operators have such loose precedences >:|

1 == x & y should not be parsed as (1 == x) & y

Yeah

== is the problem here though, not bitwise operators

Frick ==, all my homies hate ==

Even with that issue fixed, IMO bitwise operators should always require parentheses. They're not frequently used enough for anyone to develop intuition for their precedences

Browncat Programs

Personally I think bitwise operators should have a tighter precedence than addition

^^ (damn you Redwolf for posting that message)

4:48 PM

lol

Browncat Programs

Being between addition and multiplication is the best way to do it imo

eww wtf why

@BrowncatPrograms Mmm, I'd be very surprised if 1 + 3 | 8 was parsed as 1 + (3 | 8)

Browncat Programs

Hmm, true

@ASCII-only You can do val <pattern>=<expr>;<case body> instead

@user Transcript for 2019-01-01

Uh, that took a while

Browncat Programs

Honestly I don't really think bitwise operators are important enough to not just be functions instead

4:56 PM

Some languages might need them, but yeah

Browncat Programs

In C or maybe even Java they make sense, but using them in JS or Python is pretty rare (as far as I know)

@NathanMerrill Hey, mine too!

@AaronMiller I suspect user is searching for all references to scala

@BrowncatPrograms The thing about making them functions is that some libraries use them a lot in some places and a lot never use them, so you're putting the previous group at a disadvantage if you remove them entirely

@pxeger Yes :P

Browncat Programs

Wait is Nathan Merrill still active?

4:58 PM

Not here, at least

@cjfaure Try Scala first, it's a lot easier than Lisp

Browncat Programs

@user yeah, look at a lot of binary encoding libraries (e.g. that need "int -> array of bytes" or bitmask packing)
