A: Sandbox for Proposed Challenges

PythonMasterComposite Factorization code-golf

 
How many bots are there here?
 
None at all.
In this chat rooms, machine users are forbidden (except ElectionBot on elections).
 
Then whose New Sandboxed Posts?
 
@PythonMaster If you're talking about the feed bots, there are five or so, I think.
 
That's an RSS feed, not really a bot.
 
4:03 PM
@PythonMaster A feed bot which is allowed, too.
 
User-written bots aren't allowed in here though; they have free reign in Beep Boop Maggot.
 
@El'endiaStarman Six.
 
Okay that makes more sense
 
Woot, accept day! 6 is a new personal record...
 
4:06 PM
Nice answer plus 1500 rep bounty: meta.stackexchange.com/a/273285/278543
 
@NewSandboxedPosts Uhm, why did you post this in the sandbox after posting it on the main site @PythonMaster?
 
Yes I am cheating since it's in a different site but it makes me feel better about my self-esteem when compared to the Jon Skeet of PPCG :)
@Doorknob I may have felt a little too confident about my questions and proceeded to post my question but then had a little trouble on the way then I posted in the Sandbox...
 
@Dennis how much rep did you get from me
 
90 points.
 
@Dennis I hope you enjoy those points
use them wisely
 
4:10 PM
Finally got Trendsetter!
 
@orlp Spams 500 rep bounties...
 
i always do. Every single one gets me one step closer to taking over the world Martin.
 
Oh we already knew how to get it :(
 
@Dennis I have solved this equation and found that Martin = the world
I'm #21 by all time rep
soon I will be top 20!
muhahahaa
@Dennis have you played TIS-100?
 
No, I haven't gamed in years.
 
4:16 PM
Just as a favor, can someone like give me some pointers on how to improve on my questions in general?
You can make your pointers for this question too: codegolf.stackexchange.com/questions/104925/…
 
@Dennis it's a 'game' in that you write programs inside a dedicated application :P
I can highly recommend it
 
That sounds interesting. Let's see if I can set up Steam.
 
I'm 75th by year rep. Nvm that I've been on PPCG since July.
 
@Dennis basically the 'game' is you have a bunch of parallel microprocessors
that communicate with eachother through ports side by side
and a very small instruction set
each microprocessor can hold like ~10 instructions that it will repeatly execute over and over
using those you must complete all kinds of challenges
 
I absolutely can't copy anything in GitHub Gist.
 
4:19 PM
@Dennis and once you've solved the problem the goal is to do it with minimal cycles, or minimal instructions
 
GitHub's clipboard handler is absolutely borked.
 
like code golf
 
function greet(greeting, name) {  return greeting + " from " +         name + " on " +         navigator.userAgent + " at " +         new Date().toISOString();}
 
That sounds like the perfect game for me. :)
 
@orlp I see what you're doing. Distracting Dennis for long enough to overtake him...
6
 
4:20 PM
This resembles nothing like a greeting function, more like crap.
 
@Dennis the reason I ask is because I kinda wanted to have a PPCG TIS-100 competition
where everyone spends <period of time> on the same challenge
and we compare solutions afterwards
 
Gimme money and I might buy the game ;_;
 
Maybe a nested-programs TIS-100 challenge? :3
You have n cycles to return the nested program.
Or m instructions.
 
@orlp That sounds fun. I'' check it out when I get home.
 
s/\'\'/\'ll/
@mınxomaτ XD
 
4:26 PM
@NewMainPosts how did this stay open for over an hour when it's an exact duplicate?
 
... don't know how to feel about this
 
I'm experiencing a blocker bug right now on GitHub, with IE 11.
Every newline is absolutely ignored.
Is anyone else experiencing this?
 
Lol I don't have IE but I'm not experiencing that on Chromium
 
2 hours ago, by flawr
user image
 
Yup, this one.
 
4:39 PM
@orlp Holy smokes, did you just convert Dennis to the dark side?
Wow, mad props. Just in time for the winter sale too.
 
Is it maybe the "\r" messing it up? Maybe they only tested on non-Windows systems
Idk why "\r" would do anything but I also dunno why it'd do that at all
 
@redstarcoder I suspect people would have noticed earlier...
 
How long has it been an issue?
 
It also doesn't happen on Chrome (at least, not for me).
 
Does it on Firefox?
 
4:42 PM
If it is a CRLF issue knowing Google they probably convert to Unix line endings when pasting
 
That's what I was thinking
 
It works fine on Firefox but I'm on Linux
 
Same
 
So that's probably a good guess actually
 
Who created the database of TNB posts, again?
 
4:44 PM
@LegionMammal978 @El'endiaStarman
 
@El'endiaStarman Could I use the database for some personal experiments?
 
@LegionMammal978 Hmm. I haven't yet figured out how to make the database downloadable.
What sort of experiments did you want to try?
 
@El'endiaStarman Have a certain chatbot idea, only need post IDs and content (markup)
 
@LegionMammal978 Hmm. My database doesn't have the user-typed content.
 
@El'endiaStarman HTML should also work
 
4:48 PM
@El'endiaStarman That's easy to get:
oh wait, nevermind
That gets HTML
@LegionMammal978 There are some modules for converting HTML to Markdown you could use
 
@quartata See ^^^^^
 
I actually did discover how to get user-typed content, and minxomat downloaded the entire TNB transcript that way. His piece-of-junk computer lost the data though.
 
I was thinking /message/<id>
But that's HTML.
 
@El'endiaStarman Oh well, I just need the HTML and ID
 
I swear, I remember it being Markdown....
 
4:51 PM
I do want that stuff in my database though, and I also want to figure out a way to maintain stuff like stars.
 
It's stored somewhere since editing
 
Ta-da. (Wait, no, you're right.)
 
@El'endiaStarman But yeah, would it be possible to just download the database file?
 
@LegionMammal978 That's the thing though; I haven't figured out how to do that yet.
 
@El'endiaStarman Is it hosted on the cloud or something?
 
4:54 PM
@LegionMammal978 Nope. It's stored on a shared hosting server.
 
But it's a giant PostgreSQL instance
You can parse the transcript yourself pretty easily. @LegionMammal978
 
Fine...
 
Do you want code?
 
I'll write it up myself
 
Yeah, the actual transcript parsing doesn't take as long as the database transactions.
 
4:56 PM
@LegionMammal978 What are you actually trying to do, anyways?
 
So transcript requests aren't rate-limited?
@quartata Genetic algorithm for TNB-like chatbot
 
9 mins ago, by LegionMammal978
@El'endiaStarman Have a certain chatbot idea, only need post IDs and content (markup)
 
@KritixiLithos yeah, didn't have that
 
Ah, ninja'd more specifically. :P
@LegionMammal978 Not that I could tell.
 
Need actual TNB data for training data
 
4:57 PM
@LegionMammal978 Kind of vague... what would the genes be parameters for?
If you need reply data I don't recommend searching for all replies. I tried that myself and it takes way too long.
 
@quartata Certain string operations
 
Sep 25 at 0:10, by El'endia Starman
TIL that there's actually a web page where you can get the raw content of messages as the user typed them. Only works per message though, so far as I know. Example.
 
@quartata Just going to look at the following message
 
I do the message directly after, pings within an hour, and replies within 10 days. The message after is rarely relevant though, surprisingly.
Usually it's rare for there to be only one conversation
 
@quartata ik, but it will still be an interesting experiment
So the link for each day is http://chat.stackexchange.com/transcript/240/YYYY/MM/DD/0-24?
 
5:00 PM
Yep.
 
Yeah.
 
2161 days to go through...
 
The first three years have almost nothing.
 
Yeah, there's like an 8 month gap in 2012 too
Or was it 2011? Can't remember.
 
imagine this room going silent for a full day now
honestly I'd go nuts at work because this chat room keeps me alive
 
5:04 PM
I remember that. Fun times.
 
@Doorknob Yeah, there are some days I wish it were so....
 
@LegionMammal978: You can take a look at this (click the Run button) to see how many messages there were each day.
 
Nothing from Nov 10, 2011 till August 05, 2012
 
5:10 PM
@ETHproductions Yeah, that's what I was thinking of
 
Yeah, almost three years of total silence. Then happened, and then later, StackEgg happened.
 
5:29 PM
We need to figure out what major event should happen next to draw more traffic.
 
the purge
 
Can we preemptively assign five more room owners and three more mods?
 
a 24 hour period where all questions are open
 
@PhiNotPi The fallout?
When everything in chat dies due to the chattiquette.
(And that is happening now, even if so slowly.)
 
Can you stop about that already?
4
 
5:35 PM
On fallouts: I want to make a "fallout shelter room" from the Woods of Lurking. :3
 
I want this room thawed. :3
Can someone please thaw the woods? :3
 
in The Woods of Lurking, 16 secs ago, by Stack Exchange
El'endia Starman has unfrozen this room.
 
Thanks! :D

A: Sandbox for Proposed Challenges

Andrew LiClose your tags! code-golf string This is based off a previous deleted challenge of mine with the same name Introduction You are tasked with writing a program that returns a truthy or falsey value based on if the input has all its XML-like tags appropriately opened and closed. Consider the fol...

 
5:55 PM
when will scientists finally get their shit together and do a proper randomized double-blind trial on whether parachute use prevents death when jumping out of airplanes?
 
How would you run a double blind trial like that? It's pretty easy to tell if you've been given a parachute.
 
Is it? Could one just be a weighted bag?
 
@orlp hmm. I'm not sure if I could trust the results of a study like that. I'm pretty sure the parachute lobbyists would have their hands in it somehow
 
There, whole transcript's been parsed
> -rw-rw-r-- 1 lm978 lm978 108204727 Dec 28 12:48 out.txt
108MB, not bad
 
@LegionMammal978 Sounds about right.
 
6:10 PM
@orlp: you would need a large sample of subjects, both ones with a parachute, and ones without, to be sure... Or ask on physics.se if they can provide a reasonnable assumption (saving you a lot of lawsuits and headaches)
 
the problem
the latex source doesn't show what replies to what, right?
 
it just says @orlp
it doesn't include the reference arrow
 
@orlp I think they parsed the transcript, not individual message contents.
 
6:13 PM
@orlp Also, how is your username supposed to be pronounced? I internally pronounce it "or-lip"
 
@LegionMammal978 it's my initials
how do you pronounce initials?
I don't know
 
@orlp I knew that
 
I say orlp
 
I thought "orl - pee"
 
can you say earl gray?
now make that
orl gray
and then put a p at the end
orlp
 
6:14 PM
orl-puh?
 
@orlp "or-el-puh"?
 
@LegionMammal978 no
it's a single syllable
not sure where you guys keep getting these extra syllables from
 
o_O
 
like oglethorpe but minus the g and ethor?
 
I personally just say it like 'welp' but with the 'we' changed to an 'or'.
 
6:16 PM
@El'endiaStarman ye
 
so like oglethorpe - g_ethor
 
you see
if you can say earl
as in earl grey
 
@orlp That's what I meant by "or-lip"
Just make it one syllable
 
@LegionMammal978 - is a syllable boundary
 
I think the hard part is the 'lp'.
 
6:17 PM
@Pavel well
 
@orlp It's kinda hard to notate a phoneme boundary
^^^
 
the rl is a tongue motion
the p is a lip motion
@Pavel can you say help?
 
this is starting to get confusing
 
Yeah. It's not hard to pronounce orlp the way you say it, but it feels weird.
 
I pronounce it like el'endia but now people are getting confusing
 
6:19 PM
 
@GabrielBenamy ok
 
yo
 
o \/
  /
well that sorta looks like yo backwards even though that's not what I meant
 
Yo
 
6:23 PM
@EᴀsᴛᴇʀʟʏIʀᴋ oˋ/
 
@EᴀsᴛᴇʀʟʏIʀᴋ you can use the union and intersection math symbols to make a double height O.
 
oˋ/
yay
 
Hooray!
 
Was closing this challenge as a duplicate of this one the correct thing to do?
 
@Joey I accidentally spilled some coffee over my quantum computer, and my friend is using his to "hack into the US Government" or something unimportant, so, no. :( — Mateen Ulhaq May 3 '11 at 5:59
lol
 
6:28 PM
The former challenge is 5 years old and doesn't really meet our current spec
 
@ETHproductions Uh, the older was closed as a dupe of the newer, better one. Isn't that the way it should work? (In this specific situation, that is.)
 
I think so. I just got a comment from the OP complaining about that though
Why do you mark my question as a duplicate of yours when your question is clearly the duplicate as it has been posted later? Please rectify this decision. — FUZxxl 4 mins ago
 
Maybe you can point to my Huffman coding question as precedent.
 
Normally I dislike hard IO formats but the older challenge's IO format actually cut down on a lot of the boring built-in answers which I like
 
6:36 PM
public object LoadOrg(int cmpKey, object DO_NOT_USE_AT_ALL_EVER);
me as a lead programmer
 
It's a standard loophole at least because it's empty
 
@redstarcoder but it existed before the question (by 9 months)
 
"Cheating" or not, it's tempting to downvoters ;)
 
@Geobits sure it is. It's really just bait for this comment
 
6:41 PM
@muddyfish Yes. It doesn't fit the requirements of a language.
 
@GabrielBenamy I'm not sure if it matters or not though or is that for KC challenges only?
 
It's not possible to write programs in "factorlang".
 
@redstarcoder Empty programs are only a loophole for quines.
 
My new language is called "SquareRootButtonOnMyCalculatorLang". Now where's that sqrt challenge...?
 
It doesn't even fit a pseudo-language. There is no way to write any code, you just supply input. Otherwise, you could just create a bunch of Python / Perl / etc. programs and call them "languages".
 
6:43 PM
@GabrielBenamy That almost sounds like bash >_>
ducks
 
@Dennis ah I misinterpreted this answer.
 
@Geobits Bash is turing-complete.
 
I know. Was a joke about it also being "a bunch of etc programs" thrown together, since coreutils and such are usually counted as "part of the language" here.
 
The Incompleteness Theorem proves that FactorLang is not turing-complete.
 
6:46 PM
meaning "there is no way to reasonably encode any program into an integer, execute it in FactorLang, and interpret the output integers as your results"
 
It doesn't even produce the right output :D
 
Hahaha, wow. Spectacular failure there :P
 
@ETHproductions I know I don't post here very often any more so my opinion won't count for much, but closing a 5 and a half year old question as a duplicate of a 2 day old one seems akin to accusing an author of a 100 year old book of plagiarism because someone wrote something very similar last week. I can see why the author of the original challenge might feel slightly aggrieved.
 
Then again, languages such as Bubblegum are just as powerful as Python
 
@Gareth When it comes to duplicates we tend to keep open the better worded question (please correct me if I'm wrong)
 
6:48 PM
You just have to crack cryptographic hashes
 
@LegionMammal978 That one time when you write a bubblegum answer and it end's up executing as Python

Q: Closing old question as duplicate of a new one

Martin EnderWhat is our policy regarding closing an old challenge as a duplicate of a new one? I know this happens on other sites (at least SO), if the newer question is generally better or usually if it gathers better answers (such that the old one acts as a "redirect" to the canonical answer). Now this do...

 
@muddyfish As I said, I don't visit here as often as I used to so I'm not up to speed with what the convention is. It just looks ... odd.
 
C M C: Find a Bubblegum solution to "Hello, World!" Implement a Truth-Machine

Using the reference implementation, the code can be tested like so: $ xxd -ps -r <<< 15274d5062a99a296b6de2 > hello.bg $ python3...

6:52 PM
@Geobits as a math major, I find the mathematics of a thing to often be more interesting than the thing itself.
 
@ETHproductions Edited
 
As a not-math-major, I sometimes do. This isn't really one of those times, if only because it's not the first time "languages" like it have been tried here.
 
@LegionMammal978 Can bubblegum take input?
 
6:54 PM
It seems that you could dig through the old questions and "rewrite" them to gain reputation without really working to earn it. But, meh, it's not really any of my business. :-)
 
@ETHproductions Yes.
For example, this program takes input:
from math import factorial as F#
try:n=int(i)-1;o=n*(F(n)%-~n==n)
except:o=sum(map(int,i.split()))
 
@Gareth Long time no see, by the way :D
 
who can figure out what this function is?
 
I just read the esolangs page for bubblegum... 10/10 lang
 
f=lambda n:(4<<n*(3+n))//((4<<2*n)-(2<<n)-1)&~-(2<<n)
 
6:57 PM

@LegionMammal978 yep!
and it's not recursive
and it's not binoit's formula
 
@FlipTack No, <function <lambda> at 0x7fcc392ec9d8>
 
nor is it matrix multiplication
so what's going on here? :P
 
@orlp Dark magic?

@LegionMammal978 that's racist
 
That's lightist...?
 
it's african-american magic

Perhaps the old factorization challenge shouldn't be closed anyway... It has a different output format, after all (2^4 as opposed to 2,2,2,2)
 
You can't use big ints to index into lists
