Adám's new ad gave me idea for the mobile app. What do you think? codegolf.meta.stackexchange.com/a/13987/30525

Adám

@BetaDecay Yeah, the design is… Ugh!

J. Salle

IBM employees had a sense of humour back in the 70s, eh? Hahahahah

Beta Decay

@Adám Mm, I'm afraid that's the best I can do

Erik the Outgolfer

@Adám you were warned :p

(although a bit...late if I may say so)

J. Salle

Adám

BEWARE OF SEEMINGLY CORRECT OPERATION

REAL MOTHER TASK ..

Erik the Outgolfer

tfw you read "just 1 byte"

caird coinheringaahing

@EriktheOutgolfer What challenge?

Erik the Outgolfer

a comment

although that's not important

I can understand why they say so, it's just the feeling you initially get a little bit

caird coinheringaahing

Also, if a language had the commands: add the inputs, prime test the inputs and given a starting configuration, simulate GoL, does that make it a) Turing-complete and b) able to be used here?

Erik the Outgolfer

5:06 PM

what are the "inputs"?

J. Salle

@EriktheOutgolfer just wait. In a couple of weeks they'll be like OMFG I SAVED A FRIGGIN BYTE YEAH

Erik the Outgolfer

also a) implies b)

caird coinheringaahing

@EriktheOutgolfer CLA's for instance

Erik the Outgolfer

@J.Salle depends on situation

caird coinheringaahing

@EriktheOutgolfer Well, in case a) was "no", then I wanted to include b) as a follow-up question

Erik the Outgolfer

5:07 PM

and if the byte save is clever or trivial

@cairdcoinheringaahing just sayin'

the way you phrased it seems like you're asking if both are true

J. Salle

@EriktheOutgolfer fair enough

Erik the Outgolfer

;p

also @cairdcoinheringaahing I think gol is turing-complete so yes a) will most probably be true

caird coinheringaahing

@EriktheOutgolfer Thanks. Brb, making that language :P

Erik the Outgolfer

good luck simulating gol

btw you'd need arbitrary bounds

J. Salle

Yeah I'd love to see a language with a documentation like: Function X: Simulates GoL

caird coinheringaahing

5:09 PM

@EriktheOutgolfer I've done it on a non-infinite board size, which is the best that can be currently done

Erik the Outgolfer

@cairdcoinheringaahing making it theoretically infinite is what makes it tc

caird coinheringaahing

@J.Salle HQ9++ says that the command ++ makes it tc. Doesn't say how though :P

J. Salle

@cairdcoinheringaahing ~magic~

caird coinheringaahing

@J.Salle s/magic/Jelly Oh, wait. They're the same thing :P

J. Salle

caird coinheringaahing

5:12 PM

> ++: Increment the accumulator twice, and instantiate an object of a new sub class of the generic super class. Due to the best principles of object hiding, this object cannot be accessed in any way.

Really, HQ9++? That's more useless than + in the original

Erik the Outgolfer

tl;dr: nothing

it's really just HQ9 but + doesn't cause syntax error

caird coinheringaahing

Does a page on esolangs.org about esolangs count as a quine?

:P

J. Salle

Depends on whether you consider quines only for programming languages or for anything, I guess?

Erik the Outgolfer

what if "Text" was considered a programming language

it's only capable of producing quines

and it's output only, finite output

caird coinheringaahing

@EriktheOutgolfer That's a subset of Charcoal

J. Salle

5:16 PM

Willing to bet that someone would manage to use it to solve a challenge.

Erik the Outgolfer

@cairdcoinheringaahing but some chars do different things in charcoal

it's neither a subset nor a superset imo

Poke

@EriktheOutgolfer it's not turing complete so i don't think it could compete on ppcg

caird coinheringaahing

@EriktheOutgolfer Yeah, but all ascii characters are outputted in charcoal, so literal quines are very easy, just like in "Text"

@Poke Languages don't have to be tc, just be able to add numbers and perform a prime test

Erik the Outgolfer

on top of that I don't think that rule is effective anymore

(although some still do consider it to be)

DJMcMayhem

@EriktheOutgolfer Some people have done that.

IMO, such answers are only worthy of downvotes.

Funky Computer Man

5:19 PM

@Poke You don't need to be a language to compete

Poke

@cairdcoinheringaahing k well "Text" can't take input so this still doesn't work

caird coinheringaahing

@DJMcMayhem Not unless the solution is genuinely clever. But 99% of the time, downvote into oblivion

Poke

@FunkyComputerMan Most challenges ask for programs or functions. How do you answer without a language

J. Salle

It could take input if we build an interpreter I guess?

DJMcMayhem

@cairdcoinheringaahing If you can show me an answer written in "text" that is actually genuinely clever, I'll eat my hat.

caird coinheringaahing

@Poke Check his latest challenge :P

@cairdcoinheringaahing That would be why I said "most"

caird coinheringaahing

Erik the Outgolfer

@Adám Mm that's nice. I'll add it now

Erik the Outgolfer

@Adám umm...citation please? how can you be sure? :p

J. Salle

@cairdcoinheringaahing mathematically 99.9999999... = 100

Thomas Ward

@J.Salle I challenge you to prove this. :P

Adám

@EriktheOutgolfer special features as found in the graduation design userscript I read that as meaning the design too. Even if not, the app has a relationship to the userscript, and will look good with it turned on.

J. Salle

@ThomasWard if you transform it into a fraction you get 999-99/9 = 900/9 = 100

DJMcMayhem

5:27 PM

@ThomasWard It's easy if you acknowledge that the notation ... means the previous digit or sequence of digits repeated an infinite number of times

caird coinheringaahing

@J.Salle 99.9 recurring != 100

J. Salle

Well (999-99)/9*

DJMcMayhem

@cairdcoinheringaahing That is completely false.

Erik the Outgolfer

$99.\overline9=100$ wat

J. Salle

@DJMcMayhem that's how I learned it hahah

Erik the Outgolfer

5:29 PM

so is $0.\overline3=0.4$ true in the same sense as $99.\overline9=100$???

Beta Decay

@ThomasWard x=99.9999..., 10x = 999.9999...., 10x = 900 + x, 9x = 900 => x = 100

caird coinheringaahing

ಠ_ಠ Why does C need a separate void to interpret Deadfish?

DJMcMayhem

@EriktheOutgolfer No because 0.3¯¯¯ == 1/3 and 1/3 < 0.4

Thomas Ward

i think i started hell...

Erik the Outgolfer

Erik the Outgolfer

also honestly how do you prove $99.\overline9=100$?

Thomas Ward

@cairdcoinheringaahing perhaps you should :P

DJMcMayhem

@EriktheOutgolfer 0.9999... equals 9(1/10)^1 + 9(1/10)^2 + 9(1/10)^3 ... 9(1/10)^N as N approaches infinity. The limit of that sum is 1.

varsitytutors.com/hotmath/hotmath_help/topics/…

wikimedia.org/api/rest_v1/media/math/render/svg/…

caird coinheringaahing

@ThomasWard I would, but you ninja'd me :P

Also, I hate OO based languages. C# needs a class to interpret a language with 4 commands

Erik the Outgolfer

5:33 PM

@DJMcMayhem you could also argue that $0.\overline01=0$ so $99.\overline9=100-0.\overline01=100-0=100$...?

Thomas Ward

@cairdcoinheringaahing :P

DJMcMayhem

Also, a more intuitive rather than algebraic proof is that if 0.999... < 1, then there exists an n such that 0.999... + n == 1. What is that n? Because it's going to be 0.000...1, but that 1 will only happen after an infinite number of 0's. You can't have something after an infinite sequence.

@EriktheOutgolfer Ha, ninja'd sort of

caird coinheringaahing

@ThomasWard Although... now you have to deal with them rather than me, so thanks :P

Thomas Ward

@cairdcoinheringaahing unless my internet dies

which is 100% likely

caird coinheringaahing

@ThomasWard RIP Lasereyes' internet.

Thomas Ward

5:34 PM

no, RIP Penn State Library internet connection due to maintenance

Erik the Outgolfer

@DJMcMayhem hmm...it's just kinda unbelievable how $99.\overline9=100$ actually holds true isn't it

Poke

@cairdcoinheringaahing i think they're supernovas

not lasers

DJMcMayhem

It's because your intuition of numbers breaks down once you start dealing with infinity.

J. Salle

@EriktheOutgolfer Calculus is ~magic~ I guess?

DJMcMayhem

TBH, it's really the same thing as 1/2 + 1/4 + 1/8... == 1

caird coinheringaahing

5:36 PM

@Poke Sacrilegious! They are widely known to be universe-destroying lasers!

DJMcMayhem

Because as long as you actually do that and actually add them together, you'll never technically reach 1, but if you do it to infinity, the limit is 1, so for all intents and purposes, the infinite sum is 1.

And in binary, that's like saying 0.1111111 == 1, which is pretty equivalent to 0.99999 == 1 in decimal

@cairdcoinheringaahing so tempted to unstar...

:P

Thomas Ward

@DJMcMayhem You really should join us...

DJMcMayhem

@EriktheOutgolfer Have you studied any calculus?

caird coinheringaahing

Given that you have to add some number, x to 0.9999..., in order to make 1, 0.999... cannot equal 1

@DJMcMayhem Freedom of speech :P

DJMcMayhem

@cairdcoinheringaahing So what is the value of x?

5 mins ago, by DJMcMayhem

Also, a more intuitive rather than algebraic proof is that if 0.999... < 1, then there exists an n such that 0.999... + n == 1. What is that n? Because it's going to be 0.000...1, but that 1 will only happen after an infinite number of 0's. You can't have something after an infinite sequence.

Erik the Outgolfer

5:39 PM

@DJMcMayhem well, kinda although not that much yet I have school requirements and stuff and no time :(

caird coinheringaahing

@DJMcMayhem 0.000...1

J. Salle

I actually can't stand Calculus

But I like number theory so there's that

DJMcMayhem

@cairdcoinheringaahing That value is by definition infinitely small.

The 1 does not exist

caird coinheringaahing

@DJMcMayhem But it is still a value. Ergo, there is a value between 0.999... and 1

Thomas Ward

@DJMcMayhem this should be argued over in the math room IMO xD

DJMcMayhem

5:40 PM

@cairdcoinheringaahing No, it's not. Because if it comes after an infinite number of 0's, that implies that the infinite number of 0's ends. Otherwise nothing can come after it.

lim x->+inf 100-1/10**x = 100. It's wrong to say that 99.999... = 100, because it doesn't. You need to talk about it in the realm of limits for it to make any sense.

caird coinheringaahing

@DJMcMayhem ^^ What Adam said. Also, this is starting to get into discussions regarding infinity, which tend to break my brain :P

99.999... is infinitely close to 100. The difference is infinitesimal. But infinitesimal is not zero. Welcome to calculus :)

@Adám Unfortunately, that would probably count as voting fraud, but you could just give him a bounty when TIO reaches a landmark (400 languages for instance)

Others could answer with other sites too, and get upvotes for that.

@cairdcoinheringaahing Puh-lease! Tetris GoL was solved so easily not

@Mego CIA penguin!

Anonymous

@J.Salle Well, we knew how to solve it. Actually building the pieces and putting them together was the hard part. Really hard challenges are the ones where you sit there and stare at them, not knowing how to begin.

caird coinheringaahing

@Mego Hell yeah! You changed it! We officially have the coolest RO of all rooms :P

Actually, I took a double take when you said "we", because you no longer look like Mego at the first glance :P

I don't know how long I'll keep it like this, because I prefer the transparent background. I suppose it would be easy to add transparency but meh.

DJMcMayhem

@Mego Weird... It should have had transparency since the original one did, and I didn't bother to change it

Just a sec

caird coinheringaahing

@Mego If (when) you do change it back, please add the current one to your profile :P

Leaky Nun

I can write detailedly the motivation behind, or I can completely skip it and write down with results... which should I choose

Anonymous

@DJMcMayhem I think the upload to my profile picture messed up the transparency

Leaky Nun

I've already written half a page worth of background

caird coinheringaahing

6:41 PM

@LeakyNun For what?

Leaky Nun

@cairdcoinheringaahing for my next challenge

DJMcMayhem

@Mego Ah, yes. You uploaded it to imgur rather than using gravatar like your last one.

Anonymous

The transparency probably would've worked if I had uploaded it to Gravatar instead of SE

DJMcMayhem

The one I have sitting on my desktop is transparent

caird coinheringaahing

@LeakyNun Write a brief motivation paragraph

DJMcMayhem

6:41 PM

Ninja'd ;P

Leaky Nun

@cairdcoinheringaahing it can't be brief

Anonymous

There, it should work now, after it refreshes

caird coinheringaahing

@LeakyNun Then don't have a motivation part. That isn't really part of the challenge, and shouldn't take up a lot of space

DJMcMayhem

Weird, they have the same URL, but the one in your profile has ?s=328&g=1 appended

Anonymous

I think it's because I uploaded it by URL instead of by image data

OK, now I just need one more codegolf challenge for the APL tournament. Anyone have a good idea for something really array oriented?

Anonymous

@Adám What do you have so far?

DJMcMayhem

@Adám I just posted an array oriented challenge yesterday. No APL answers yet

Anonymous

Feel free to use any of my challenges (with attribution, of course)

DJMcMayhem

Technically today actually (silly UTC)

I'm sorry, I take it back

UTC isn't stupid.

Adám

@Mego Generate a bar chart with ten bars. Model disease spread. Chess knight moves. See if there are only two of each unique. GoL. Group elements by value. Find which interval things fall into. Isomorph subarray.

hi all

J. Salle

UTC = GMT?

Neil

@Adám GETS IT'S? Apostrophitis has reached APL\360?

Adám

@J.Salle Mostly.

caird coinheringaahing

@J.Salle 1 hour after IIRC

Adám

@Neil Not the only typo I've seen.

caird coinheringaahing

6:52 PM

20:00 GMT = 19:00 UTC (I think)

Anonymous

@Adám Ooh, modeling disease spread is one of my favorite problems. I should write a challenge about that :P

Anonymous

@J.Salle Depends on DST/BST/whatever iirc

J. Salle

@Neil It's been an issue since the 70s apparently

caird coinheringaahing

@Adám Wait, GoL? How long is a vanilla Life in APL?

Also, how do you make images smaller in posts?

Anonymous

@cairdcoinheringaahing Use HTML instead of Markdown

J. Salle

6:54 PM

I never learned UTC. The standard time here is GMT-2/3/4/5 depending on where on the country you are, so I think they never bothered teaching other time zones in school.

Adám

@cairdcoinheringaahing The classic one is 34.

Anonymous

@Adám Try running Tetris on it :P

caird coinheringaahing

@Mego I don't know HTML, what tag is used for images? waits for all the ninja's

Adám

@cairdcoinheringaahing img

Anonymous

@cairdcoinheringaahing <img src="whatever.png" width="x" height="y">

flawr

6:55 PM

@Mego Please use ... /> instead of ... >

J. Salle

or ...></img> but I don't know why would anyone do that

Adám

@cairdcoinheringaahing So far I've been able to golf that by over 40%

Anonymous

@flawr That's only necessary for XHTML, and so it adds no benefit in HTML

Adám

@J.Salle I think that's invalid HTML.

DJMcMayhem

@Mego Why hasn't your profile updated yet?

Anonymous

6:57 PM

@DJMcMayhem Caching

J. Salle

@Adám is it? I don't think I've ever used it that way, I just assumed it would work

Anonymous

@Adám It's valid, but unnecessary for HTML.

Adám

@J.Salle Of course it will. The browsers swallow pretty much anything. They'll be happy with <img src=whatever.png width=x height=y too!

J. Salle

@Adám html is weird hahahahah

Neil

@J.Salle For most intents and purposes, yes. Note that UK is currently on BST before it goes back to UTC ~a month from now

Anonymous

6:58 PM

Actually I misspoke earlier - ... /> isn't valid XHTML. It does absolutely nothing in HTML except make it ever so slightly clearer. But omitting the slash is golfier.

Adám

@J.Salle No, the browsers are.

J. Salle

@Adám that too

Anonymous

At least we don't have to deal with IE7 compat anymore :P

J. Salle

@Neil yeah, we'll enter DST in ~a month from now here

Neil

@Mego: it's needed for embedded SVG and MathML
