@Phoenix Jelly, 4 bytes: DSDS

it means get digits -> sum -> get digits -> sum

Mr. Xcoder

15:06

@EriktheOutgolfer That's the most "normal" Jelly code I have ever seen.

Phoenix

@EriktheOutgolfer Wouldn't that only perform two iterations?

Erik the Outgolfer

yes isn't it supposed to?

Phoenix

> e.g. 5689 -> 28 -> 10 -> 1

Adám

@BusinessCat Can you explain it?

Phoenix

It's supposed to do it recursively

Erik the Outgolfer

15:07

you mean digital root?

Phoenix

IDK what digital root is

Erik the Outgolfer

sum digits until you end up with one digit

Leaky Nun

No, you just have to mod it by 9

and replace 0 with 9

Erik the Outgolfer

@LeakyNun that's %9ȯ9 in Jelly

Phoenix

Right, or use Business Cat's fancy formula.

Adám

15:08

@Mayube Hm. I can abuse this.

Business Cat

@Adám ^^^ and ^^^^^

@Phoenix That is my formula

Leaky Nun

I thought the formula would be famous.

Business Cat

Phoenix

oic, x-1 == ~-x

Erik the Outgolfer

Business Cat's is ’%9‘ in Jelly...

@HelkaHomba that url tho

Phoenix

Why does mod 9 work though

I confuse

DJMcMayhem

@BusinessCat Why do you decrement then increment? Why not just take mod 9?

Adám

@Phoenix J: 9&|&.<:

totallyhuman

15:16

44 -> 4 + 4 = 8
44 -> 44 % 9 = 8

Adám

@DJMcMayhem To avoid 0 when divisible

totallyhuman

45 -> 4 + 5 = 9
45 -> 45 % 9 = 0

DJMcMayhem

Ahhh, I see

Q: Can I assume that the input will always be within the printable ASCII range (0x20-0x7E)?

Many challenges don't specify what characters the input consists of, so I often assume the input will only consist of printable ASCII chars. Is my assumption correct? Note that this mostly concerns string-related challenges.

Adám

From the PPCG user languages genealogy:

Looks like a rail yard.

As long as it's more readable than the languages themselves, it's fine.

Why is java not pointing at javascript

It was very clearly inspired by java

JavaScript

JavaScript (/ˈdʒɑːvəˌskrɪpt/), often abbreviated as "JS", is a high-level, dynamic, untyped, interpreted run-time language. It has been standardized in the ECMAScript language specification. Alongside HTML and CSS, JavaScript is one of the three core technologies of World Wide Web content production; the majority of websites employ it, and all modern Web browsers support it without the need for plug-ins. JavaScript is a multi-paradigm language, since it supports prototype-based with first-class functions, imperative, and functional programming paradigms. It has an API for working with text, arrays...

It was called JavaScript to match the name of Java. Java being the chosen compiled language, while JavaScript was the otherwise unrelated chosen scripting language.

Downgoat

@Phoenix well it's not why, but it is influence by Java a lot

Phoenix

15:26

> JavaScript was designed with Java's syntax and standard library in mind.

If wikipedia says it, it must be true.

it is worth noting that Oracle own the trademarks to both names

Business Cat

Why does my CMC answer have 4 stars

Downgoat

@BusinessCat nature.com/nature/journal/v438/n7070/full/438900a.html

Mayube

which is why common JavaScript is officially called ECMAScript, because "JavaScript" is a proprietary trademark

Downgoat

15:28

nature is like top journal so good citation

Phoenix

@BusinessCat There is a citation

totallyhuman

@BusinessCat because it's clever ಠ_ಠ

Phoenix

@BusinessCat 5, and because it's really coool.

Erik the Outgolfer

why does just referencing stars get you stars these days? I just don't get it...

Mayube

Because stars are a meaningless resource that give nothing to the receiver and cost nothing from the giver

2

Erik the Outgolfer

15:32

they actually cost something from the giver...you can only star 20 messages per room per day

Mayube

that means they're a finite resource, not that they cost the giver

Adám

Should C# go back into the chart? Or maybe .NET should be added as a non-lang?

Erik the Outgolfer

think of it as the giver being given 20 stars for each room to give per day...

Mayube

@EriktheOutgolfer stars which have no other purpose, logically speaking if you don't star 20 messages per day, you're wasting stars

Erik the Outgolfer

so why waste them on just star references then?

Mayube

15:35

Because there's not much else to spend them on

Downgoat

sorry was cleaning keyboard

totallyhuman

ok that's enough

ಠ_ಠ

Mayube

The only reason people even care about star spam is because there happens to be a "star board" that shows recently starred messages

Erik the Outgolfer

please stop that abuse can't we even have a conversation without abuse

Mayube

@Downgoat it's not me

Business Cat

15:36

@DJMcMayhem Pls clean stars

Downgoat

oh, sorry >_<

@BusinessCat also pls do a suspend of abusing person

Erik the Outgolfer

ROs can't suspend

Downgoat

tru, ok well they can kick ban at least

Adám

@Downgoat But can they see who starred?

Erik the Outgolfer

nope

not even mods can see that

Downgoat

there is a script tho

you cannot match repeated letters

Kritixi Lithos

@Downgoat matches only permutations upto length 2

@Downgoat what kind of system?

@Uriel You have to pass a test to get credit for the class, but they require you to do the course

which is dumb because course is easy
