So what should I change in this? I don't see what's bad about it.
 
Just wait and see. Also, I strongly recommend to leave your challenge at least 48-72 hours in the sandbox ;)
 
I didn't think of getting out of here without modifications though xD It's not here for nothing at least. I hope.
 
@V.Courtois I should say my challenges are utterly awesome and no one steals them :)

2:04 PM
I recommend spending the 48 to 72 hours answering challenges on PPCG :)

Q: Increasing Goldbach partitions

Olm manThe Goldbach conjecture states: that every number that is greater than 2 is the sum of two primes. We will consider a Goldbach partition of a number n to be a pair of two primes adding to n. A number is of increasing Goldbach partition, if the smallest prime used in one of its partitions i...

 
@Mayube Exactly!
 
@LegionMammal978 should we include summer time?
 
@Mendeleev :o such horror. must fix
 
2:14 PM
> (not including DST)
 
oh for a moment I thought dst was a timezone or something
that is, why discrimination?
 
D aylight S avings T ime
 
@trichoplax Wait, as in, ROs can do that? Or do you need an RO from the other side / a mod?
 
Isn't +8:45 a thing, or am I wrong?
 
@ZacharyT There's quite a few wonky timezones
 
2:15 PM
hmm, lotta CEST folk around here
and by "lotta" I mean 2
 
@ZacharyT Apparently it's unofficial
Government-wise, anyway
 
AFAIK all of China uses Beijing time
 
How did you get China out of that?
 
@ZacharyT I didn't, just a random tidbit that I happen to know
 
Then why reply to me?
 
2:19 PM
I'll probably re-ask this throughout the day (every 3 hrs or so) to prevent bias
 
about bias: strawpoll.me/12492628 was 2 left and 1 right when i asked first, then i asked 12 hours later and it's now 13 right 2 left
 
Jim
@LegionMammal978 +1
 
@Jim Then respond with it in the poll
 
Jim
@LegionMammal978 Oh that's actually a link! I was wondering why nobody answered…
 
@LegionMammal978 UTC -7
 
2:23 PM
@DJMcRamen See ^^^
 
I did
 
upload.wikimedia.org/wikipedia/commons/a/af/… 30° is UTC+2 and 45° is UTC+3. We were using UTC+2 with DST, now it's UTC+3 all year. wtf
 
Turkey
 
Timezones are screwed up.
like, really screwed up.
 
2:38 PM
we should all use UTC
and go to work at 22 and return home at 6
 
There's that ... or the option which would be correct (although more confusing) an infinite number of time zones.
 
But then I'd have to stay up till 4:30 in the morning every day
 
i agree with the infinite number of time zones; the sole problem is that we should develop way better watches (that update IRT).
 
Another, more logical system:
(end timezones would be ±12:00 depending on the side of the antimeridian they're on)
 
we tried ^^, but failed horribly
 
2:45 PM
Hey, does anyone even inhabit the +12:00 timezone?\
@betseg Stupid politics!
 
@ZacharyT northern new zealand island?
 
But yeah, Turkey would be split between UTC+02 and UTC+03
 
@LegionMammal978 I actually like this the least. You really want cities to be in the same time zone
 
-6
Q: Anaconda ınstall problem

Ozanwhen ı tried ınstall the Amazon 2 and 3 for Windows 10 64 bit my computer gives those warning: failed to create anaconda menus failed to initialize anaconda menus what is the reason and how can ı fix this.

 
> ı
the guy's turkish
 
2:46 PM
And yet ... he uses i as well
 
¯\_(ツ)_/¯
 
@NathanMerrill I was thinking of generally keeping them along these lines, but rounding them to the nearest "major" political boundaries (countries/provinces/coastlines/whatever)
 
isn't that pretty much what we did?
 
What I meant to say: does anyone inhabit the -12:00 zones?
 
Just look at the IDL
 
2:48 PM
@ZacharyT some islands in the pacific
 
@ZacharyT No, just uninhabited U.S. islands
 
right, but there are real, political reasons we did it that way :)
 
@LegionMammal978 That's not logical, because you're cutting a sphere up like a rectangle
 
@StepHen It's more logical than our current system
 
@StepHen Not even a sphere ...
 
2:50 PM
@LegionMammal978 No way Jose, not if you live on the edges of that map, you need to change your projection first :P
@ZacharyT an almost-sphere
 
and the planet is tilted
 
@StepHen Which projection do you want me to render it in?
 
@HyperNeutrino Oh good point - they would either need to be a room owner of both rooms, or a mod
 
Relevant XKCD: xkcd.com/977
 
2:54 PM
umm...same xkcd
 
No...?
 
They are not the same XKCD ... whatsoever.
 
Does this projection make you happier, @StepHen?
 
@LegionMammal978 Yes
 
3:00 PM
> The preferred form is "xkcd", all lower-case. In formal contexts where a lowercase word shouldn't start a sentence, "XKCD" is an okay alternative. "Xkcd" is frowned upon.
 
> It's not actually an acronym. It's just a word with no phonetic pronunciation -- a treasured and carefully-guarded point in the space of four-character strings.
So, yeah, xkcd it is!
 
Great - less shouting :)
 
Wait, no, I found an even better and more clear projection:
 
Are Asia and North America really that much bigger than Africa and South America? That's an eye opening projection if so
 
$100% totally
After all, Africa does completely fit into the U.S.
 
3:07 PM
(Cylindrical) equal area map for reference: en.wikipedia.org/wiki/…
@LegionMammal978 Might as well do this every hour or so ... to further prevent bias.
 
@ZacharyT Nah, then I'd be 11'd for noise
 
11'd ?
 
Slang for mod action
 
Where does that slang come from??
 
Apr 12 '16 at 6:31, by Dennis
@Sherlock9 mod abuse -> mod abuse!!! -> mod abuse !!11!1!! -> mod abuse !!eleven!1!! -> mod abuse eleven -> eleven
 
3:11 PM
Fascinating.
(w/o DST)
 
WTF is that?
Link?
 
I thought the point of UTC was so that we wouldn't have to all use different timezones?
 
The Craig retroazimuthal map projection was created by James Ireland Craig in 1909. It is a modified cylindrical projection. As a retroazimuthal projection, it preserves directions from everywhere to one location of interest that is configured during construction of the projection. The projection is sometimes known as the Mecca projection because Craig, who had worked in Egypt as a cartographer, created it to help Muslims find their qibla. In such maps, Mecca is the configurable location of interest. Given latitude φ to plot, latitude φ0 of the fixed location of interest, longitude λ to plot, and...
@trichoplax More so that they were all standardized
But yeah, apparently this projection preserves direction to the centerpoint
 
Is someone just trying to trick us, or does someone here actually live in UTC+14:00 ?
 
3:21 PM
it doesn't exist
 
It exists all right.
 
UTC+14:00 is an identifier for a +14 hour time offset from UTC. This is the earliest time zone on earth, meaning that areas in this zone are the first to see a new day, and therefore the first to celebrate a New Year. This is also the latest time zone on earth, meaning that clocks show the latest time of all zones. UTC+14 stretches as far as 30° east of the 180° longitude line and creates a large fold in the International Date Line. == As standard time (all year round) == === Oceania === Kiribati Line Islands - including Kiritimati (Christmas Island) The IANA time zone database zone identifier is...
 
Timezones are really screwed up.
 
But yeah, they're used for the Southern Line Islands year round, which are uninhabited
Part of the big notch on the IDL
 
3:24 PM
Does Christmas Island (Kiribati) use UTC+14?
 
@ZacharyT Ugh:
UTC−00:25:21 is an identifier for a time offset from UTC of −00:25:21. == Usage == UTC−00:25:21 was used in Ireland as Dublin Mean Time. Dublin Mean Time was introduced by the Statutes (Definition of Time) Act, 1880, which also defined Greenwich Mean Time (GMT) as legal time in Great Britain. This Act replaced local mean time, which had been held to be the legal time since Curtis v. March in 1858, throughout the United Kingdom of Great Britain and Ireland. From 2:00 am Dublin Summer Time on Sunday 1 October 1916, the Time (Ireland) Act, 1916 changed the time used in Ireland to be the same as that...
 
was
 
I used to think that there were only timezones from UTC-12:00 to UTC+12:00
 
@KritixiLithos Well ... you were wrong ... so wrong
 
In today's internationalized age, everyone using UTC all year round, and sleeping/working at different hours is the only thing that makes sense.
 
3:26 PM
@ZacharyT Wait, you're right
@Adám And getting rid of DST
 
@LegionMammal978 Edited. Thanks.
 
"Mauri" then if they do live there ...
Otherwise <insert look of disappointment>
 
@V.Courtois Actually, that's how they used to do it. Of course, back then nobody had autocorrecting watches. Or radios.
 
I thought back then they had even more time-zoney-region-things.
 
Infinite (I think)
 
would Is the cube of the sum of my digits divisible by me? be considered a dupe of the existing Am I divisible by double the sum of my digits??
 
@Mayube Probably not
But maybe
 
@Mayube try to be original
 
@LeakyNun this is the internet, originality is dead
5
Everything's an iteration on a theme
 
3:48 PM
we measure originality, not be if elements have been reused, but how similar two things are

A: Sandbox for Proposed Challenges

Colonel PanicIntroduction Ten years ago, a secret encryption key used by DVD players was published online. When the industry tried to censor it, the internet reacted by republishing it widely—creatively incorporating the key onto shirts, a flag and even in song. If this code golf community had existed, I'm ...

 
Hey, can someone tell this user why their answer is invalid?

JohnPython 2 or 3 (62 61 bytes) "oks" in __import__('requests').get("http://isup.me/"+u).text where u is defined as the website to test. Original answer by Score_Under, improved & fixed by me.

I gotta go
 
I'm not sure if I know why it's Invalid
 
I am not sure about anything anymore

Question: is there anyway to 'bundle' a python module with the program?
I have like foo/main.py but I want to not require the user to have to manually find and install the module, is there like an equivilent of node_modules?
 
I don't know.

Q: Simulate Alpha Decay

caird coinheringaahingAlpha Decay is a kind of radiation decay where every time the atom "decays", it loses a helium nucleus (an alpha particle). This means that an atom loses 2 protons and 2 neutrons each time. Your task is to simulate this. Given two integers as input, m and p, where 1 < p < m, count down in steps ...

 
@Okx I can see you deleted your 05AB1E answer...where did it fail?
 
5:14 PM
This is driving me crazy. Who did Olm man used to be?
 
wheat wizard
 
@cairdcoinheringaahing wheat wizard
 
aka einkorn enchanter
ninja'd
 
aka millet mage
 
So ... many name changes.
 
5:17 PM
Quinoa Quack
 
...did you just change again
 
Maize master
 
Which timezone are you in (minus DST):
https://strawpoll.com/1xcgg2e
 
@ZacharyT check my profile
list of all my old usernames
 
@EinkornEnchanter Oat Occultist
 
5:18 PM
Someday I'll find a username I like
I like that one, I was looking for one with Oat
 
Cereal clairvoyant
 
rep cap :-(
 
Straw Shaman
@EinkornEnchanter Ooh, new favorite: Papyrus Palmist
 
@Adám I wish
 
I prefer the grains, but to each their own
 
5:21 PM
Is there anything that could go with Barley?
 
Thats one I have been thinking about
Buckwheat is another B as well
Rye and Rice are two Rs
 
How about Farro Fortune-teller?
 
pretty good
 
Great ... and this won't get trashed.
 
why would it?
 
5:26 PM
It's a long discussion of potential usernames related to grains.
 
Isn't that what TNB is for?
 
<insert look of disapproval>
 
CMC: Output the square root of a non-negative integer, if it is a perfect square, else output its square.
 
@ZacharyT ಠ_ಠ
 
dude you need to install the userscript or "<insert look of diapproval>" is gonna make up 90% of your contributions :P
 
5:28 PM
4 -> 2
5 -> 25
9 -> 3
0 -> 0
 
Nah, I actually like using <insert look of disapproval>, for some reason.
 
@ZacharyT <insert look of disapproval>
 
@totallyhuman what userscript is this? There are 2 many to count
 
ಠ_ಠ
@cairdcoinheringaahing i think it's chat commands
 
TacoScript ?
 
5:29 PM
one of them, yes
 
@totallyhuman do you have a link?
 
@ZacharyT Dunno ಠ_ಠ
 
Let's stop the ಠ_ಠ's
 
we've used 3 :P
 
5:31 PM

@ZacharyT <insert look of disapproval> to your last comment
Anyone?

CMC: Output the square root of a non-negative integer, if it is a perfect square, else output its square.
Can this actually become a challenge on Main, if one needs to handle any integer?
 
APL, 18 bytes {⍵=⌊⍵*.5:⍵*.5⋄×⍨⍵}.
 
@Mr.Xcoder Jelly, 5 bytes: ½²Æ²?
 
Nice.
 
@EriktheOutgolfer Oh wow. That's way shorter than what I tried: Try it online!
 
5:34 PM
Question: Why are there always only 2 mods in here at once? I've never seen more or less at the same time.
 
not always
 
There's 0 right now
 
alex is inactive usually
@DJMcMayhem aren't martin and dennis here?
 
@DJMcMayhem I think @cairdcoinheringaahing means including the greyed ones.
 
all mods are ghost right now so there are essentially none...
 
5:35 PM
There in the user list, but greyed out, so they're not really here
 
and i haven't seen doorknob often
 
including greyed they're 3
except if you only include site mods
 
I've got martin and dennis greyed out
 
@EriktheOutgolfer There are only Martin and Dennis.
 
that's only the site mods
 
5:36 PM
I don't see Doorknob or AlexA
 
@EriktheOutgolfer Does the ternary always take exactly one atom for each clause?
 
@EriktheOutgolfer whos the third?
 
@EriktheOutgolfer What were you talking about then?

@cairdcoinheringaahing Trichoplax
 
5:37 PM
@DJMcMayhem one link
 
@totallyhuman What is the purpose of %1?

Well there's where my knowledge of jelly ends. I can't tell exactly what makes up a link or how the arguments pass through
 
@EriktheOutgolfer Thx, I see now.

Isn't a number 0<n<=1 truthy in pything?
 
@EriktheOutgolfer Even though your approach is waaaay shorter, can you see anyway to do this without resorting to two links?
 
@Downgoat Clarify
 
@Downgoat unclear
 
@Downgoat No clue what you're saying
 
confoosed
 
5:39 PM
@DJMcMayhem Ʋ¬‘²H*@
 
@ZacharyT Any number except 0 is truthy in Python. Were you talikg about another language pything?
 
@ZacharyT whta part did confuse
 
or Ʋ¬‘²H⁸*
 
Wait, wouldn't that be Ʋ¬‘²H*⁸ instead?
 
@totallyhuman It was in reply to this message.
 
5:41 PM
@DJMcMayhem * isn't commutative
 
Oh, never mind.
I'm stupid.
 
Is the link's left argument the result of passing a through Ʋ¬‘²H or just plain a?
 
former
but the second alternative I mentioned isn't quite obvious like that
 
That seems backwards... That should give (2 or .5) ** a, not a ** (2 or .5)
 
5:42 PM
Stephen S
 
14 ninjas moved to Trash
 
welp
 
@DJMcMayhem ah thank you
 
hmm is it possible to move the trashing message to trash?
 
@DJMcMayhem it doesn't exactly work like that
the ⁸* part is a nilad-dyad pair which would have the nilad () as the first argument of the dyad (*) and the current value as the right argument
 
5:46 PM
I still don't quite understand. Ʋ¬‘²H is a chain of monads, so it's effectively a monad itself. So <monad><left-arg><dyad> seems like it would compute monad(a)<dyad>a not a<dyad>monad(a)

@EriktheOutgolfer Oooh.
 
@DJMcMayhem chain of monads isn't one monad
 
It isn't?
 
5:46 PM
they just contribute to the current value
 
Clearly I understand even less jelly than I thought
 
@EinkornEnchanter stop changing your name.
 
@DJMcMayhem I think even Dennis feels the same (p.s. he created jelly) afaict
but it shouldn't be much of a problem
 
@EinkornEnchanter (to others) It's not polite to ignore a Stawpoll.
 
@totallyhuman No. If I try it, it silently fails
You also can't move timeout messages
 
5:49 PM
aren't those called audit messages?
 
I think so
 
@EinkornEnchanter Jenga
 
lambda n:n**(n**.5%1and 2or.5)
 
Ok, GTG, sya tomorrow when I will be able to post some more stuff.
 
5:50 PM
it's a term to avoid move, timeout, description change, owner change, freeze, delete, etc.
 
@totallyhuman Better now
 
@StepHen Perhaps, in Jenga balance is generally good.
 
About Jelly, I recently had posted my first jelly answer which I am still unsure how it works, I went to the atoms page and then selected few atoms and played around the combination to make it work somehow.. :D
 
@Mr.Xcoder mm, abusing python's whitespace requirements to the fullest
 
Isn't that how most people answer in Jelly?
 
5:51 PM
there's also jelly hypertraining
 
@totallyhuman Pfff, Python should be called non-whitespace
 
@totallyhuman you must enroll yourself to that...
and it's preferable that you want to learn jelly to completion and you're not that busy
 
How DO YOU ALL learn golfing languages? And how do you type the strange characters? Do yo copy-paste from the codepage?
 
@EriktheOutgolfer Thanks for helping explain, I just have one more question. How does your first version work? Is it like <monad><dyad> is effectively a<dyad>monad(a), so <monad><dyad>@ is monad(a)<dyad>a?
 
@Mr.Xcoder sometimes copy-paste sometimes compose key
@DJMcMayhem oh that's simpler
 
5:53 PM
@EriktheOutgolfer Like ALT+sth?
 
Ah, I had thought jelly hypertraining was for advanced jelly thing only.
 
@EriktheOutgolfer What do you mean?
 
@officialaimm advanced? no, it's intended for beginners
 
@EriktheOutgolfer Wrong ping
 
@Mr.Xcoder jelly was designed to be able to be typed from the US international keyboard layout
 
5:54 PM
@DJMcMayhem Ʋ¬‘²H*@ behaves as you would expect a normal chain to
 
I think I'm better off golfing in Python :)
 
@totallyhuman Yet, not all US international keyboards allow you to type all of the commands.
 
BYE!
 
Ʋ¬‘²H is just normal quickless stuff, *@ means * with arguments reversed (the difference is changing the flow of implicit arguments)
 
5:55 PM
bye
 
Well, bye then.
 
Btw I couldnt make jelly work on my pc(numpy dll load error on windows). So, I have to completely rely on tio. How consistent is TIO with the regular jelly interpreter?
 
@ZacharyT wut? isn't there only one?
 
@officialaimm install numpy
 
Nope.
 
5:56 PM
@officialaimm since dennis maintains both jelly and tio, it's updated quite often
 
For example, some US international keyboards don't let you type all the superscripts.
 
@DJMcMayhem write access granted
 
Thanks guys.
 
How long does it take for a display name to change?
 
@ZacharyT instantly
o_o
why didn't it work?!
 
6:01 PM
Unless you're talking about chat. It takes a while in chat.
 
Hey Dennis is here! Now I have to go again
 
Thanks Dennis!
 
@cairdcoinheringaahing Um, I'm not sure how I feel about that.
 
lol
Yay! It changed.
 
6:02 PM
@Dennis Unless a mod clicks refresh profile from parent site. Then it picks it up rather quickly.
 
Can't you do that yourself?
 
You tell me.
 
Has it changed? I just refreshed
 
It has.
 
Stop. It. Wheat/EinkornEnchanter/OlmMan/...
 
6:04 PM
@EinkornEnchanter But you don't have a button. You just switched between parent sites. Right?
 
@Zacharý I was just demonstrating I'm back.
@Dennis yes, but if I switch to the same site it will refresh, at least I think it will, I've done it before
 
6:19 PM
@Dennis what do you mean? (I really can't leave this place, can I?)
 
6:45 PM
chirp
 
I KNEW EINKORN ENCHANTER WAS WHEAT WIZARD
 
Um ... okay ...
 
@Mr.Xcoder I have my keyboard layout:
 
o0 how do you do anything on that
 
@totallyhuman WHat do you mean? I type.
 
6:53 PM
i just meant that it's so complicated
even the space key has extra characters
 
@totallyhuman It is all very mnemonic. AltGr+Space is non-breaking, and AltGr+Shift+Space is M-space.
@totallyhuman The APL characters are in their standard (mnemonic) positions, and the dead (i.e. prefix) keys are basically overstrikes.
 
Imagine trying to squeeze Jelly into that mess ... :|
Anyone said APL uses too much symbols?
http://www.ccs.neu.edu/home/samth/fortress-spec.pdf
 
@Zacharý I wouldn't. I'd have one keyboard for each language. I currently use the above for APL, ASCII, and all Western European languages, but switch to Hebrew layout for Yiddish and Hebrew.
