@Phoenix node.js

@ASCII-only You could probably have started a node.js process from python and piped things into it so you don't have to port anything.

@Phoenix 2 interpreted languages = so much overhead

Someone sent me a bunch of suggestions on how to make my code shorter, and I no longer know what it does: tio.run/##KypNqvz/XyXeNr24NElDX0/…

@Phoenix Why does that output alot of semicolons?

Are ruby flags +3 or +1 bytes?

> I no longer know what it does

4:06 PM

Oh.

Depends if you normally need a flag to run Ruby

Iirc there's a -e or something that lets you run code from a command line argument?

So if you can use that it's only +1 for another flag

@programmer5000 Although I think that it's because they just aren't ever removed from the input.

user165474

@programmer5000 Note how long ago I posted that message, and how long ago the first answer was. I was 15 seconds earlier than the first answer btw because it probably won't show up :P

user165474

I like how my net rep change today is positive somehow

You haven't been serially downvoted enough today

4:14 PM

lol

user165474

I have been -100'd though for bounty

I basically understand how it works, but I have no idea how gsub is being used on its own like that.

Just noticed that the redesign userscript adds a cool underhanded 404 page

I've found myself spending all day at work thinking of cool trivial challenges to post :P

the scrolling on this webpage makes me angry: hhs.gov/ohrp/regulations-and-policy/belmont-report/index.html

That's weird, was chat just down for you?

It was for me

Yep

user165474

Chat went down earlier for me as well.

Woah, PPCG has 3 4(!) questions in the HNQ

user165474

:D Yay

user165474

4:33 PM

...i see none

I see 6 on stackexchange.com

PPCG is probably the best community for HNQ for its size

Worldbuilding is comparable but is alot bigger

user165474

Oh you're looking there

user165474

Hey Mayube is on TNA (edit: Top Network Askers)

TNA?

user165474

4:37 PM

Top Network Askers

So are you

user165474

ooo actually?

user165474

ehh i'm far down lol

Yeah, a few PPCG peeps are

user165474

Why is "TNA?" starred? Please unstar

user165474

4:38 PM

22 hours ago, by Hyper Neutrino

Whoever is starring all these messages, please stop. You're going to run out soon because you only get 20 stars per room per day

Maybe if I get around to asking a question I can be on there

user165474

lol you have 0 questions wow

I can't think of any good ideas :|

@HyperNeutrino Okay Dokay

user165474

wait ro can unstar

user165474

4:40 PM

ooo

Yup. I've done it several dozen times in the last two days

user165474

right :I

I abused stars once I laughed to myself, then unstared

user165474

kek

CMC: Alternate the case of the input

user165474

4:42 PM

s/stared/starred

wait wat

For example, the input "Hello world" should give either "hElLo wOrLd", or "HeLlO WoRlD"

user165474

@DJMcMayhem Jelly, 2 bytes: Œs (misinterpreted)

user165474

sorry i lied

Does that not work?

4:43 PM

@TuxCopter WHAT. That makes no sense. Choose your own WEBSITE packages!? I would die. No PPCG.

user165474

No, it swaps the case of everything

V, 5 bytes: Vuòl~

@TuxCopter ...bing is in the lowest package instead of google... What fresh hell is that?

Q: Validate 2Col syntax!

As a couple of people may have noticed lately, I've largely abandoned development of Braingolf because it's boring and uninspired, and moved on to 2Col which is a little more interesting, and not designed to be a golfing language. The defining feature of 2Col is that every line of code must be e...

code-golf string

@BetaDecay Hey I like bing. I mean I get paid to use bing :D

Erik the Outgolfer

4:45 PM

@HyperNeutrino then what do you suppose "alternate the case of the input" to mean?

xD

@BetaDecay The problem is more that this thing is breaking net neutrality

@Christopher If I got paid to use a shitty search engine, I would like it too. :P

^

user165474

@EriktheOutgolfer Every character has opposite case of the characters on either side of it

4:45 PM

@EriktheOutgolfer It should alternate irrespective of the case of the input.

@TuxCopter Meh, net neutrality, schmet neutrality, it's actually usability that's troubling me

Erik the Outgolfer

oh then Hyper's solution indeed doesn't work

But I assume Jelly can lowercase the input in one byte, right?

@DJMcMayhem Look up Microsoft rewards :P

Erik the Outgolfer

no

4:46 PM

That's what V does, just slightly more verbose

I have made ~15 bucks

Lowercase all, swap every other

Erik the Outgolfer

it has a 2-byte builtin Œl

should it start with lower or upper case?

user165474

either is fine

Either one is fine

4:47 PM

@BetaDecay seriously, an ISP having a data plan like just for facebook isn't a problem?

Ninja'd

user165474

lol

Erik the Outgolfer

@DJMcMayhem dilemma :/

The V answer can be trivially modified to start with either one: Just swap the l and the ~

Erik the Outgolfer

Jelly starting with lower, 8 bytes: ŒlŒuJḤ$¦

4:48 PM

I thought my dad stole my burrito. I almost attacked him but noticed he didn't take my burrito.

Erik the Outgolfer

Jelly starting with upper, 8 bytes: ŒuŒlJḤ$¦

@TuxCopter That's where the usability fails

Erik the Outgolfer

@DJMcMayhem can I assume the input will only contain letters?

Hmmm...

user165474

CMC: Swap the case of a number :D

4:50 PM

I want to say no so that my V answer is more competitive :P

How about just letters and spaces

Actually, that gives me an idea for a different (harder) CMC

Given a string, alternate the case of the letters but ignore all the non-letters

Erik the Outgolfer

@DJMcMayhem then it would make my Jelly solution longer :(

So "Hello world" --> "HeLlO wOrLd"

user165474

might it include weird non-alphanumeric and non-whitespace

For the new CMC, it can contain any printable ASCII

user165474

:I

4:52 PM

Another test case: "#include <iostream>" --> "#InClUdE <iOsTrEaM>"

This one can start with upper or lower

So there's no restriction on starting case?

Yes

CMC: a-z <-> A-Z, ! <-> ¡, ? <-> ¿

user165474

:o

user165474

@BetaDecay can we assume that input will not contain null bytes

user165474

4:57 PM

Also I am emitted by you.

Erik the Outgolfer

@HyperNeutrino you're emitted to him too

user165474

?

Antineutrinos travel backwards in time

7

wait what

user165474

ooo

4:59 PM

So they get emitted to something

how?

false

Dunno, ask Feynman, it's his theory

Erik the Outgolfer

@BetaDecay I meant emitted from something to something else

user165474

s/its/it's/g

user165474

5:00 PM

Also can we assume that the input will not contain null bytes

Erik the Outgolfer

@HyperNeutrino = very common typo it's worthless to fix

user165474

:(

@HyperNeutrino Yes

Erik the Outgolfer

damn caret reply

user165474

yay

user165474

5:00 PM

@EriktheOutgolfer lol heh

user165474

I find it convenient

user165474

welp rip got to go now

it appears crappy on the starboard

Yeah, just starred than unstarred

5:08 PM

is it ok if i place a bounty on my own question?

Of course

im adding it to URL wardialer then

Erik the Outgolfer

@KuanHulio you will lose most of your rep that way...

yeah

not worth it

only have 84 rep

Hey, does anyone know what the SE app for Android is like now? I always used to prefer the mobile site

5:09 PM

I'm thinking about posting that CMC to main. Should I say First letter can be upper or lower or should I make it start with one or the other?

And should it have to be consistent?

@BetaDecay Still garbage. I only have it for push notifications.

Good to know

Hey @Dennis, someone mass downvoted me overnight on my quine submissions, all of the quines from RosettaCode and three of my own...

It would be great if someone produced a PPCG-specific app... Something along the lines of the userscript... Anyone here know how to build an Android app?

Erik the Outgolfer

there's somebody called roomowners here...

@BetaDecay I am a noob at making Android apps

5:13 PM

Probably so they get pinged when someone puts @roomowners

@KritixiLithos Better than nothing :D

@EriktheOutgolfer programmer5000's chatbot

Erik the Outgolfer

well chatbots don't go in TNB normally...or should I say at all

@EriktheOutgolfer What about New Main Posts?

Erik the Outgolfer

that's actually SE chat feeds masqueraded as a bot

@MDXF Those votes, assuming they were indeed cast by the same user, would probably get reversed automatically.

5:17 PM

@Dennis Even if I deleted most of them?

Erik the Outgolfer

you shouldn't delete just because of serial downvoting

Antineutrinos travel backwards in time

please don't star link to message star original message, because it doesn't appear correctly on the starboard (also don't abuse...)

@MDXF No clue.

Erik the Outgolfer

well, if antineutrinos go back in time, does that mean time traveling is possible???

at least going backwards only

@EriktheOutgolfer

Special relativity

In physics, special relativity (SR, also known as the special theory of relativity or STR) is the generally accepted and experimentally well-confirmed physical theory regarding the relationship between space and time. In Albert Einstein's original pedagogical treatment, it is based on two postulates: The laws of physics are invariant (i.e. identical) in all inertial systems (non-accelerating frames of reference). The speed of light in a vacuum is the same for all observers, regardless of the motion of the light source. It was originally proposed in 1905 by Albert Einstein in the paper "On t...

Is that what you are looking for?

Nope: when I say antineutrinos go backwards in time, what I really mean is that an antineutrino is the normal neutrino going backwards. If normal matter goes backwards, it becomes antimatter

Q: PPCG-specific Android App

This is probably off-topic, but it would be very handy, so I'll just put this here. Basically, I was wondering if anyone could develop an Android app which would serve as a browser for PPCG. Maybe something along the lines of the pre-existing SE for Android app. However, this would be specific t...

Causality cannot be violated

@EriktheOutgolfer I'm making some (1, 2) chatbots, ignore them.

@programmer5000 What's with those names?

@NewMetaPosts kotlin!

kotlin?

5:22 PM

I mean... We can make it in kotlin

The language

Erik the Outgolfer

@BetaDecay well then we could have ourselves go back in time by creating a couple converters converting us to anti-matter, put ourselves into the smaller one, put the smaller one into the bigger one, then use the bigger one to convert the smaller one (and thus ourselves) to anti-matter...wait that doesn't work

Ohhh

It's quite nice actually

@EriktheOutgolfer FYI I'm not in the intellectual position to have an extended discussion about this... You'll have to wait until I've finished reading my book on relativity

Erik the Outgolfer

@DJMcMayhem btw can you please clear the stars from my onebox?

they certainly don't belong there

thanks :)

5:26 PM

:shurg: sure.

I also starred the original

Erik the Outgolfer

what is a shurg?

lol

a typo

:shrug: ?

It's a shurg

Erik the Outgolfer

@DJMcMayhem albeit a very subtle one

5:27 PM

What else could it be :P

wait nvm neutrino oscillation is with different flavors

Q: AlTeRnAtE tHe CaSe

For today's challenge, you must write a program or function that alternates the case of a string. However, you must ignore non-alphabetic characters. This means that every alphabetic character must have a different case than the preceding and following alphabetic character. This is slightly more ...

code-golf string

(removed)

@NewMainPosts Why did that get starred?

Somebody liked the challenge?

5:35 PM

They could've upvoted, though

Or the bot is just getting general appreciation

It hasn't been getting a lot of it the past few days

tfw you have an entire page of answers dedicated to -1's :(

serial downvoting

rip

@KuanHulio Yep

Waiting for the system to reverse it

Now I'm afraid to post more quines (of my own)

Hm, those quines doesn't looks very golfed

5:41 PM

Some of them are satirical, some are as golfed as the language allows

Some are in languages where it's pretty impossible to write 'golfed' code, such as the two assembly quines

Meh, someone made a mandelbrot in a x86 binary in 50 bytes IIRC

@TuxCopter That's incredibly impressive, you should link so I can upvote

idk the question

Assembly is extremely hard to golf in...

But it's fun to see what's possible

64 bytes, close enouh

5:45 PM

@MDXF you have 14 answers on that quine challenge... wow

@MistahFiggins I love quines, but some of them are from the RosettaCode quine page (and they're marked as being so)

yeah

it's just that they make up 20% of your answers

20.290%

@MistahFiggins :shrug:

Erik the Outgolfer

@MDXF reversed?

only the three others are -1 now

@EriktheOutgolfer Nope, someone upvoted four of them

Erik the Outgolfer

5:52 PM

there's the sandbox if you wanna test

@EriktheOutgolfer There's a Sandbox room?!?

Erik the Outgolfer

yeah and you post whatever nonsense you like there

@EriktheOutgolfer So it could be renamed Ninja and nothing would change? :P
