@Fatalize holy smokes

@Poke Do you play Overwatch? I recently saw someone named "Poke" in an Overwatch video

Q: Jam don't add like that

Background Jelly's arithmetic atoms vectorize automatically. In fact, x + y is well-defined whenever x and y are numbers or ragged arrays of numbers. Jelly's source code implements this behavior using a generic vectorizer, but for this challenge, we'll only consider addition of integers and nest...

code-golf arithmetic array-manipulation

El'endia Starman

@Upgoat Aye, and when you asked him that question, I was basically the only other mod in the room.

12:55 AM

@TimmyD If you're bored: I know a language which needs help fixing array tokenization bugs ;)

< Unprintable object of class "Boolean" with literal value undefined >

undefined is Boolean confirmed

\o/

@PhiNotPi that's cool and all, but what do the colors mean? I mean, when I am playing the game of life, I see only black and white.

El'endia Starman

@BaldBantha There's a thing called the OTCA metapixel, which is a 2048x2048 construct in Game of Life that is capable of simulating any Life-like rule. Variations of Life is a simulator for Life-like rules where you can mix the rules. That's what you see there, with the colors.

@BaldBantha blog-phinotpi.rhcloud.com/2016/05/30/intro-to-metapixels

Kinda ninja'd

so its not legit GoL or....

Because changing the rules sounds shady to me... I mean I'm sure its still technicaly the GoL but...

1:21 AM

No, it's Game of Life. They're using a construct that simulates another rule

so it's a program inside regular GoL that simulates GoL with different rules?

@BaldBantha yes

Essentially

Oh ok i get it now.

Do mine eyes deceive me or does this keyboard have 24 function keys?

1:32 AM

@HelkaHomba yeah it does

That was common once.

It's also got one of those pain-in-the-ass spots between the arrow keys ><

@Dennis I guess I'm too young to remember, and I can remember when computer mice were rectangular :I

What's a mouse?

I didn't own one, but I have seen it. Can't remember where.

1:39 AM

@Geobits Strange, didn't notice. Though that might be useful as jump or something in a game

Eᴀsᴛᴇʀʟʏ Iʀᴋ

@CᴏɴᴏʀO'Bʀɪᴇɴ Next time you need a comic thingy for cergos, I have a weird ass-drawing.

(not of an ass)

red spiders + flaming unicorn / dragon + dude in imperial jail cell

@Geobits that actually looks pretty cool

Here come the "Hai"s...

Cᴏɴᴏʀ O'Bʀɪᴇɴ

If it's not of my ass, I'm strictly disappointed :p

Eᴀsᴛᴇʀʟʏ Iʀᴋ

...

The dragon was actually intended to be a flaming unicorn, but it turned into you?

so it does have your (sketched) ass in a sense

Cᴏɴᴏʀ O'Bʀɪᴇɴ

That sounds sketchy

Eᴀsᴛᴇʀʟʏ Iʀᴋ

@HelkaHomba idk it's kinda difficult with hooves

Isn't typing as well?

1:55 AM

true...

@PhiNotPi just read your blog posts, interesting read

@Upgoat Maybe you can get a gigantic computer keyboard playmat, like they have for pianos.

Cᴏɴᴏʀ O'Bʀɪᴇɴ

conorobrien-foxx.github.io/blog/update.html and bai

@NathanMerrill thanks

what's the smallest graph where 1 node has exactly 1 edge and every other node with N edges? (no loop connections)

N = 1 is 2, N = 2 isn't possible, N = 3 is 6

er, I don't think an even N works

Eᴀsᴛᴇʀʟʏ Iʀᴋ

2:07 AM

@CᴏɴᴏʀO'Bʀɪᴇɴ BAI

You must be feeling better if you are on the computer active at 22:00...

any of you guys play path of exile?

@EᴀsᴛᴇʀʟʏIʀᴋ 04:00 here

I do

rarely

Eᴀsᴛᴇʀʟʏ Iʀᴋ

no and lol

El'endia Starman

@orlp I was the Exile in Knights of the Old Republic 2, but other than that, no. :P

@NathanMerrill are you going to play in phrophecy?

starts in 18 hours....

2:10 AM

er...probably no

I had no idea

I'm gna try to get to 100 in top 10

was #4 in perandus

yeah, I don't even know what half of the tasks even mean

I mean, the standard areas and bosses I'm familar with

but I didn't know there were unique bosses

does the challenge require you to do it on hardmode?

if so, anybody that actually completes it is going to be pretty epic

I think your confused

what 'challenge' are you referring to?

pathofexile.com/forum/view-thread/1666751

the set of 40 challenges that come with prophecy?

it doesn't require you to do it on hardcore

but hardcore isn't that different from regular for experienced players

2:15 AM

well, I rarely die when I'm paying attention

its when I'm mindlessly fighting, then realize I was low

that's not entirely true

the bosses are pretty tough as well

@NathanMerrill path of exile is all about knowledge

did you ever get to maps?

nope. I got about halfway through act 3

what difficulty?

normal cruel or merciless

not sure. it was a while ago, and then I started a couple of hardmode characters

I'm a very experienced player, I get to maps in around 10 hours

that means I beat act 1 to 4 three times

once on normal, then cruel then merciless

what might take you a week your first playthrough

you will learn to do in 2 hours :)

2:22 AM

experience gain is more or less fixed though

I mean, you can move the map more efficiently

but there's the same number of enemies, right?

@EᴀsᴛᴇʀʟʏIʀᴋ WTF Is that supposed to be?

well, you never got to maps :P

it's a different system

before maps

Oh spiders IC

but for regular zones, yes, there is usually about the same amount of mobs per zone

but you can replay a zone as often as possible

so it doesn't matter how many mobs a zone has for you to kill

the question is, how fast do you kill :)

@NathanMerrill the fastest way to level in poe is to basically never stop running

if you fight higher level enemies they give more xp

2:24 AM

but they also die slower

it's much more efficient to kill almost nothing and keep running

so that you're constantly around 5 levels under the enemies' level

then how do you get items?

@NathanMerrill with a proper build they should still die really quickly

you only kill big packs and blue packs (they give like 10x regular xp)

@NathanMerrill most items come from blues, rares and bosses

you skip the rares, but you kill the bosses and blues

you really don't need many items while leveling

I agree

if you're an attack based build really only your weapon matters

2:26 AM

but I didn't realize you killed the blues

if you're a spellcaster your base damages will carry you

the only thing that's important is to get resistances on your items

you want to be at 75% elemental resistance in lightning, fire and cold

resitances? is that the orbs?

(75% is the cap)

wait, you said defense doesn't matter

well, other defensive stats don't really matter while leveling on items

but in your passives defense is important

you want to pick up a lot of life nodes

Eᴀsᴛᴇʀʟʏ Iʀᴋ

2:36 AM

@BaldBantha you can see the whole thing later hopefully

@El'endiaStarman ?

El'endia Starman

@EᴀsᴛᴇʀʟʏIʀᴋ Find a copy of Star Wars: Knights of the Old Republic (1 or 2) and play it. They're good games.

The character you play in the second one is the Exile.

so, apparently, any integer >= 2 has exactly 1 representation as a sum of 2 fibonacci numbers

is there an efficient way to find the two numbers given a large N?

O_o my code works when I add a console.log but it doesn't when I remove it... >_>

err, idk, I did it by hand

3:22 AM

@Quill i have wordpress hit counter

El'endia Starman

I spy with my little eye...something that looks like...a challenge.

I think we've already done a hit counter ;)

El'endia Starman

Oh, I was talking about Helka's Hexabrackets.

@El'endiaStarman You mean me?

@Geobits link?

3:30 AM

deadmau5 ft. Gerard Way - Professional Griefers (Official Video)

@El'endiaStarman Yea, I figured. I think it would look better if they went along the bottom too. Though it wouldn't change the challenge that much.

@El'endiaStarman Maybe. It's not all that interesting imo, it's fine if someone else wants to use if before I get a chance to

Things like

@Upgoat Can't find it right now, my search-brain isn't remembering the right keyowrds. Something like "output the number of times this program has been run".

=== OUTPUT START ===
This is borked, that is borked, everything is borked dammit

10/9 best error message

@Upgoat how about "You spoiled the cheddar"

;P

El'endia Starman

3:36 AM

@HelkaHomba Ooh nice.

@Maltysen how about: your cheese is moldy. put it in the fridge already, you f*cking idiot :P

...that also works

what about drystored cheese?

@Upgoat ♫ with a bork-bork here and a bork-bork there ♫

Cᴏɴᴏʀ O'Bʀɪᴇɴ

Everywhere a bork bork

3:42 AM

Hello

\o/ \o/ \o/ \o/ \o/ Cheddar if parsing works!

@CᴏɴᴏʀO'Bʀɪᴇɴ ♫ borky-borky-bork ♫

Cᴏɴᴏʀ O'Bʀɪᴇɴ

So, when parsing works, you get cheddar?

Well shoot nvm gotta go

@CᴏɴᴏʀO'Bʀɪᴇɴ I read it as a verb

@CᴏɴᴏʀO'Bʀɪᴇɴ bai

Only thing left on Cheddar before first release is for loops, I guess :D

3:44 AM

and a decent logo

I like the logo

@Quill ಠ_ಠ

@Upgoat you should call the raise keyword bork

@Upgoat While loops?

like bork ValueError()

3:46 AM

@zʏᴀʙiɴ101 I will add whiles and a bunch of other stuff by v1.0 just trying to get a working version 0.1-alpha out first.

@Quill okay, then which one then do you like:

user image

@Maltysen he has like a meme mode or something

@Quill I do

build with grunt install --memeify

@Upgoat With ifs and whiles you can just use syntactic sugar for fors

@Upgoat I can't remember which I voted for before, but it wasn't the one you chose. anyway, it was a joke

@Upgoat 4th down on the white bg

3:47 AM

@HelkaHomba but if I implemented whiles I'd have to make do whiles which are complicated

those can be syntactic sugar too I'd reckon

@Upgoat shouldn't it be the same syntax as an else (post condition)

do whiles are just no-precondition loop postcondition keyword

that's mostly like an else if

idk, if parsing is already pretty ugly

oh god why

@Quill y u no AST?

3:52 AM

ast?

abstract syntax tree

my compiler knowledge is AST (actually shit, thanks)

@Quill was that in response to my code?

yes

Dark orange on black

3:55 AM

@Quill do you know if switch statement's cases create new scopes?

(function(){
    this.a = "3";
    switch(4){
        case 4:
            console.log(this.a);
            this.b = "CATS";
            break;
    }
    console.log(this.b);
})()

cases are like if loops, no new scope

\o/

halp, how does cheddar interpreter work

How to make Cheddar with Mad Millie Hard Cheese Kit

@Upgoat It has just come to my mind that you might just go with infinte loops and a break!

Whiles and fors are just syntactic sugar with that!

@zʏᴀʙiɴ101 oh no, I forgot if statements :|

4:08 AM

:(

guys, I'm making a twitter

this is big news

guy, I'm happy that you make a twitter

this is large news

@Quill done

yo @PhInOTPI, does your blog have a feed

> PhInOTPI

@Quill blog.phinotpi.com/feed

Also, I got the links to stay on the same domain \o/

it's still absolute links (so now the rhcloud domain is broken), but shrug

you should connect that feed up to IFTTT and let your tweetir tweet newe blog posts

What exactly do you do with the feed?

ninja'd

user image

:O :D \o/

5:32 AM

IFTTT is pretty magical

else if should be evaluated exactly the same as ifs right?

basically

So doing this: won't break anything, right?:

            case "":     // If-statement
            case "elif": // Else-if statement

it will break

\o/

5:37 AM

else if is a post-condition, if you use it like a normal if, it'll just be a normal if

~~fingers~~ hooves crossed this will work first-try

meaning it won't obey the first condition and they'll just become independant ifs

;_; it doesn't work

cheddar> var a := true
cheddar> a
true
cheddar> if a { print "a is true" }
cheddar> if a { a := false }
cheddar> a
true
cheddar> if a { print "a is true" } else { print "a is false" }

2 mins ago, by Quill

it will break

@Quill working on it

5:39 AM

@Quill ಠ_ಠ ;_;

awesome, I read nearly all of the new tweets in my twitter feed, but I generally miss out on conversation in chat, so this'll definitely help me catch your posts :)

@Quill do you catch up on bloggoat? :D

it doesn't end up in my twitter feed, so no.... :p

@Quill ;_;

@Quill solution

halp, why are so many inappropriate accounts following me >_>

@Upgoat I had a radical idea

what about sidegoat?

5:49 AM

Leftgoat = Chathuahua

frontgoat?

@Quill do you know if typeof ... !== "undefined" is slower than ... != undefined?

there's probably a perf for it

@Quill I can imagine the chaos when ifttt gets hacked.

that said, there's probably a better way to do that

5:51 AM

cheddar> var a := true
cheddar> a
true
cheddar> if a { print "a is true" }
"a is true"

\o/ \o/ \o/ \o/ \o/ YASSSSSS

@Quill jsperf is down ;_;

that wasn't your else though

@CᴏɴᴏʀO'Bʀɪᴇɴ @EᴀsᴛᴇʀʟʏIʀᴋ @anyoneelsewhocares Update your cheese, I've added ifs to Cheddar!

@Quill ?

20 mins ago, by Upgoat

else if should be evaluated exactly the same as ifs right?

@Quill they aren't supposed to be?

I was just saying you didn't get else cases working yet

5:56 AM

I did

I think

idk, they are no falsy classes yet

also ternary statements pls

Should empty arrays be falsy?

Mᴀʀs Uʟᴛᴏʀ

@Upgoat What do ifs accept as conditions?

@MᴀʀsUʟᴛᴏʀ any expression

so... I think I have ifttt set up. I'll test it out probably sometime tomorrow.

Mᴀʀs Uʟᴛᴏʀ

5:57 AM

@Upgoat Does it work without braces?

@Upgoat can you do an if statement inside an if condition

@MᴀʀsUʟᴛᴏʀ yeah

@Quill of course!

Mᴀʀs Uʟᴛᴏʀ

if if if 1=1 {1 else 0} {1 else 0} {1 else 0}

TypeScript -_-

@MᴀʀsUʟᴛᴏʀ oh no, I meant they work without parenthesis not braces

no braces is good for golfing but sucks for readablilitlilility

Mᴀʀs Uʟᴛᴏʀ

6:01 AM

@Upgoat but JS supports no braces

@MᴀʀsUʟᴛᴏʀ so?

When has "JS does it" ever been a good reason to do something :P

Mᴀʀs Uʟᴛᴏʀ

@Upgoat And you leave out braces all the time

@MᴀʀsUʟᴛᴏʀ good point

Mᴀʀs Uʟᴛᴏʀ

It's bad for readability, but that doesn't mean you have to use it

idk, I don't want people doing if foo != bar != (baz * 3).map(=> (foo) foo + 2)[0] avocad.juic()

Mᴀʀs Uʟᴛᴏʀ

6:03 AM

@Upgoat Who knows, some people may want it that way

anyway, all I have left is for loops and cheddar can have it's first release

you should allow no braces and then print to stdout instantly "GO BACK TO PYTHON"

@MᴀʀsUʟᴛᴏʀ no, it's too unreadable

Mᴀʀs Uʟᴛᴏʀ

@Upgoat But golfing

Also python

If you add support to ignore colons in the wrong places, maybe a lot of valid Cheddar code could also be valid Python code

@Quill I will never print such blasphemy

@MᴀʀsUʟᴛᴏʀ oh god why no

i will never let my beautiful cheese look like that snake

Mᴀʀs Uʟᴛᴏʀ

6:07 AM

@Upgoat can you have an IIFE in the if condition?

@MᴀʀsUʟᴛᴏʀ uh?

like the JS IIFE?

Mᴀʀs Uʟᴛᴏʀ

@Upgoat Yeah

idk what you're saying

Mᴀʀs Uʟᴛᴏʀ

As in if (function(){return foo;})() { print 1; }

@MᴀʀsUʟᴛᴏʀ something wrong with if foo { print 1 }

Mᴀʀs Uʟᴛᴏʀ

6:10 AM

Actually, nvm

seems redundant

Mᴀʀs Uʟᴛᴏʀ

looks for source grammar

@Upgoat where is the source

@MᴀʀsUʟᴛᴏʀ for the if?

Mᴀʀs Uʟᴛᴏʀ

Yeah

tokenizer/states/if

Mᴀʀs Uʟᴛᴏʀ

6:14 AM

Wait how does ifs in if conditions work then

@Upgoat ^

@MᴀʀsUʟᴛᴏʀ wadda ya mean?

@Quill I was wondering, what do you think of my blog so far? (I know it's only been a single subject)

I like it

Mᴀʀs Uʟᴛᴏʀ

18 mins ago, by Quill

@Upgoat can you do an if statement inside an if condition

@MᴀʀsUʟᴛᴏʀ yeah

it calls the tokenizer again

Mᴀʀs Uʟᴛᴏʀ

6:18 AM

does if if 1 == 1 { print true } { print false } work?

@MᴀʀsUʟᴛᴏʀ no

idk what you're doing there even

Mᴀʀs Uʟᴛᴏʀ

IDK

But ^^^^^^

if statement inside if condition means if (<if statement here>) {doSomething();}

@Upgoat Use typeof foo !== 'undefined', it won't error for undeclared variables
