@EriktheOutgolfer yeah that's three years ago
 
Q: Is there any question-banned (not suspended) users on PPCG?
 
Unless one of them speaks up, you won't get an answer.
 
So, "even mods can't know"?
 
Anonymous
Oh, we know
 
Anonymous
But we can't tell
 
1:31 PM
Mods can't tell you.
 
mods do know, but must not disclose
 
ninja'd
 
Anonymous
We are bound to secrecy by a blood oath
 
also, I don't think you should ask questions like that
 
@Mego does SE keep the erlenmeyer flask vial of blood or something
 
Anonymous
1:33 PM
@ASCII-only Yes
 
I've heard a myth that the legendary Joel Spolsky holds that (big) vial of mixed blood of all mods who have ever been, with the oath written on it...
 
Anonymous
@EriktheOutgolfer Nah, Shog holds it
 
ooh, that's even worse
 
Anonymous
He also has the weird ability to extract a single mod's blood from the mixed vial when needed
 
Yeah he probably has a really sensitive centrifuge
 
Anonymous
1:35 PM
And he uses that blood for the dreaded super-duper ping, which magically summons the person to SE HQ to answer for their actions
 
That sounds like a ritual you do with pentagrams drawn with blood and candles
 
If SE granted mod powers more freely, this could be a revolution in transportation.
 
Anonymous
@ASCII-only Freehand red circles and keyboards, actually
 
@ASCII-only lol we don't endorse or condone stuff like that, blood oaths are a completely different thing
 
@feersum yeah but not everyone needs to travel to SE HQ
 
1:37 PM
Where is it, anyway?
New York, right?
 
Anonymous
Yep
 
Well thousands of people fly to New York every day.
 
@EriktheOutgolfer I know. Shog probably uses a normal DNA-activated teleportation circle
 
So it may not be that revolutionary for those who don't heart NY, but it could still be bigger than the rest of SE's business combined.
 
@Mego what happens if shog accidentally spills the blood out of the vial?
 
Anonymous
1:41 PM
@EriktheOutgolfer Are you implying that Shog makes mistakes? Blasphemy!
 
every human makes mistakes, and if he's not human he shouldn't be on SE :P
and what if somebody else purposefully hides the vial from shog?
 
Morning o/
 
does anyone know how to use python subprocess and use both a PIPE stdin and a timeout argument?
Popen works for PIPE and check_output works for timeout but neither for both
o wat nvm there's an input kwarg lol
 
@EriktheOutgolfer Maybe I'm mistaken, but I thought Shog essentially keeps the vial under maximum security?
 
cough Jon Skeet taken over by an evil spirit cough
 
1:50 PM
@ASCII-only Well, someone can easily have Legendary+14 skill in theivery, and steal it anyways.
 
@moonheart08 Yeah no Legendary+14 doesn't help when it's behind a spinlock, the only one who can get past one of those easily is Jon Skeet
 
Jon Skeet somehow encrypted the blood so even if you could get it you wouldn't be able to do anything with it.
 
lies, then Shog wouldn't have had the power to extract a single entity's blood from the mix
 
No but if you decrypt it with the correct key for an individual mod, you will get decrypted blood in one section and the rest of it will be further scrambled.
Each mod's blood is encrypted separately and they're all mixed. That way if you need to add another mod, you just encrypt it an add it in. If you need to get a single mod's blood, you decrypt the whole sample and take the decrypted part. :P
 
That doesn't sound very scalable.
 
1:57 PM
TBH, I wouldn't want to get teleported to SEHQ while, say, taking a shit
 
@NieDzejkob Yeah of course Shog draws a scrying circle on the toilet mirror first
 
yeah, the blood should be DNA-testable so that one can see which people are part of the oath, if shog approves
 
(The toilets at SEHQ of course)
 
also, that would be easy proof
 
well you just decrypt with all of the keys and DNA check the whole thing. Encrypted blood will not show results but the encrypted parts will all show results
 
1:59 PM
since when was the main topic in here blood rituals? Have you all formed a cult or something?
13
 
Yes
The cult is called PPCG
 
All hail the great Shog.
 
@moonheart08 blood oaths aren't rituals...
 
Anonymous
I started something and it got way out of hand :P
 
Shog-Niggurath, The Black Goat of the Woods with a Thousand Young
hang on wrong title
 
2:01 PM
A ritual is just what non-technical people call an algorithm.
16
 
why would they not call it a procedure instead? that's a more widely-used term
 
you mean a function, right?
 
no, not at all
 
I had a very relevant thread on bay12 for that technical joke, but i'm at school, so i can't grab it. It's a forum game where you are tech support, and, welll, things get a little eldritch. Praise purple
 
> Praise purple
 
2:04 PM
@feersum The Algorithm? :P
 
wat
 
@Dennis injoke. :P
if you go dig up the thread, and read through, you'll figure out what that is
 
for example, the procedure of waking up after an alarm is "shut the alarm off, put your clothes on, get up, make breakfast, go do basic needs, maybe a shower too"
 
> Praise in Purple-Alzheimer's Association, Huntsville, Alabama. 145 likes.
No, that's something else.
I hope.
 
it is
lol
bay12forums > all
 
2:06 PM
that's what basically every forum claims about itself...
 
well, bay12forums is actually amazing, as it's the home of dwarf fortress. :P
 
somebody else may think differently though, that's my point
 
Good point
 
I swear this "Create an H out of smaller Hs" challenge is a dupe, or I'm having some severe deja vu ...
 
sierpinski's carpet?
33
Q: Generate fractals from bit patterns in ASCII

samgakOverview Write a program that prints out simple fractal patterns given a bit pattern encoding the fractal, plus the per-generation scale factor of the fractal and number of generations. Explanation Here is an ASCII representation of the Sierpinski Carpet: Generation 0: # Generation 1: # ...

This challenge is a subset of that one actually
 
2:10 PM
No, I had thought it was something related to "I beams"
 
Still no new what if on xkcd ):
 
@AdmBorkBork I did have a similar idea CMC
 
How to I enter input to Esoteric IDE?
 
H of Hs with input k is basically Bit Patterns with input 381 k k
It seems like a dupe but I can't vote
though that one has to work for the general case so a competitive answer here would likely have to be better than just a port from there
also that one has a slightly different output format but that's not different enough
 
@NieDzejkob Debug > Input
 
2:15 PM
@EriktheOutgolfer oh, didn't see that here. Thanks!
 
@dzaima Nope, but that got me to this challenge, which is what I was thinking of, so thanks!
 
that doesn't seem like a dupe though
 
@NieDzejkob Remember that there are some menus to the right of the Help menu. Last time I constantly made this mistake.
 
hm, I'm completely unsure if this answer is valid, since flags now count as making separate languages
 
@moonheart08 TNB is hardly on-topic (about code-golf)
 
2:25 PM
no, debug is to the left
 
Of course that's different languages (unless it's somehow possible to combine both into a "bash+perl" language or something like that).
@EriktheOutgolfer I was talking about "Memory visualization" menu (Hexagony specific?)
 
each language has its own menus
 
@EriktheOutgolfer No, it's not a dupe, but in my remembering-part of my brain, it felt like a dupe.
 
@AdmBorkBork isn't it called the Hippocampus?
 
I don't remember ;-)
 
2:39 PM
that's only a part of the whole limbic system ;) (Google is your friend btw)
 
I wonder if someone has ever executed a Mornington Crescent program IRL...
 
@NieDzejkob (why not? What counts as IRL?)
 
@user202729 go to the station, buy a ticket and follow the instructions
 
No......
 
why not?
 
2:45 PM
normally people go from one station to another including the stations in-between, not going back-and-forth
 
@EriktheOutgolfer for each instruction, get on the train, wait until it stops at the desired station, and get off the train
 
yeah why would somebody want to do that irl
it's not like riding a train is any fun, is it?
 
@EriktheOutgolfer idk. Maybe it would make a good youtube video?
 
Consider that someone followed a Cook program... maybe.
Although... the dialog boxes don't really work. [Esoteric IDE]
 
3:03 PM
not Cook, but something similar has been done
 
... Chef.
 
@user202729 what dialog boxes?
 
When run on mono/Linux.
Although, as I can't compile RT.Util on Linux and have to pre-built DLL on Windows and then ..., (...)
 
lol there are ready-made binaries for Windows
no, it doesn't work on Linux
 
At least the RT.Util binary sort-of works.
 
3:10 PM
no, it should be a dll
 
... "dll binary"?
The one used with HexagonyColoere is Version: 1.0.9999.9999, which seems to be older (?) than the version used with EsotericIDE 1.0.1599.0, but the dialog boxes are better.
 
3:28 PM
Q: Why does this show version 1.0.1599, while Assembly.cs shows 1.0.9999.9999?

A: Sandbox for Proposed Challenges

Dom HastingsSelf-Validating Triangular Program code-golf source-layout restricted-source Your task is to build a program that validates that the given input adheres to the following criteria: each line is one character longer than the previous, including the last line. the parity of every non-newline...

 
@feersum were we trying to quote dr strange
The sorcerers of antiquity called
the use of this language "spells".
But if that word offends
your modern sensibilities,
you can call it "program".
 
Why is mathoverflow the only .net site?
 
@recursive Stax has really impressed me lately. And it's one of the few languages written in .NET!
 
@Oliver QUARK's interpreter is written in Rust. Does that count? :p
 
@moonheart08 why would it?
 
4:03 PM
@user202729 Because it isn't really part of the Stack Exchange network
 
@cairdcoinheringaahing what?
yes it is?
 
11
A: Mathoverflow - why so different

Mad ScientistMath Overflow has more independence than sites that went through the A51 process. They have the right to leave the network if they choose to, and a few other minor things. They were a successful site outside the Stackexchange network, based on the SE 1.0 software. The old software wasn't supporte...

 
@Oliver But its packed system is not really intuitive.
 
who cares about intuition when you're golfing though :P
 
But then you must remember to use the lower valued characters as that may help saving bytes.
CMP: Do you prefer int or size_t? (or language equivalent) (in other words, do you want to have a separate unsigned type for size?)
 
4:11 PM
@cairdcoinheringaahing it's still part of the SE network; it's just not owned by SE
it's interesting that MO has a jump ship clause in their contract
because i'm not sure how the users would be transferred
they'd probably lose their userbase
> Subject to Section 8, should MathOverflow wish to migrate its data outside of the Stack Exchange network, Stack Exchange shall, within thirty (30) days of receipt of a written request from MathOverflow, provide MathOverflow with a complete and current database that contains all the data necessary to recreate MathOverflow on MathOverflow's own servers and software. Following such transfer, Stack Exchange will cease all use of the MathOverflow database.
i can't see that applying to user data
 
Q: Regarding matrices in mathematics, rather than CS, can an element of a matrix be another matrix? Like so?
 
I think yes.
 
in fact section 8 explicitly prohibits that information being transferred
so MO never can realistically leave
haha
 
I think it could be similar to PPCGv2. Only the most dedicated would actually move
 
yeah
 
4:24 PM
@user202729 int, it's golfier :p
 
@cairdcoinheringaahing en.wikipedia.org/wiki/Block_matrix [no onebox]
 
@user202729 Hmm, that's interesting
 
@cairdcoinheringaahing I think I remember reading something where they used vectors and matrices as elements of matrices. IIRC, it dealt with multivariate polynomial interpolation
 
Need to check if my calculator will allow me to enter a matrix as a value in another matrix now :P
 
@cairdcoinheringaahing That, probably no
 
4:26 PM
You never know. It allowed me to enter a string at one point, which confused me massively :P
 
Which calculator? ...
 
ಠ_ಠ I had a C++ class and I actually enjoyed it
 
(is using C++ bad? It's faster than Python at least)
 
@user202729 Casio graphing calculator. Can't remember what model
 
I doubt it can.
 
4:28 PM
@cairdcoinheringaahing Into a matrix? WTF
 
@Zacharý My reaction exactly :P
You couldn't actually do anything with the string though. All operations (+, * etc.) just errored out
 
Since we're on the topic of calculators ... rref is the best thing to exist.
 
@cairdcoinheringaahing But can + and * be applied on normal strings?
 
reduced row echolon form.
 
4:30 PM
Reduced row echelon form
Niinja'd
 
@Zacharý No (which is why I suspect they failed)
 
(before knowing about it, I thought it was related to reference)
 
^ Same
Anyone know where I can find formulas for multiple linear regression? I've been searching, and all I've found is a bunch of estimates and stuff of that nature. I've found one formula with (x_1,x_2,y) interpolation, but I can't seem to find a general formula
 
I spend waay too much time in exams on my calculator :P I taught myself the basics of matrices in my biology and chemistry mocks :P
 
Damn, I wish I could run C code in PyCharm...
 
ಠ_ಠ It's SO... of course it's weird.
 
@Mr.Xcoder There's nothing wrong with C++ (other than the obtuse errors, ridiculous verbosity, and horrible pain using templates or libraries)
I just think it's a terrible first language to learn. If you already know how to code, C++ is worth learning
 
@DJMcMayhem "obtuse"? "angles > 90⁰"?
@DJMcMayhem Is it better than Pascal?
 
@user202729 Obviously it is better than Pascal. But still
 
> Obtuse: annoyingly insensitive or slow to understand.
 
4:37 PM
In that last post "(x_1,x_2,y) interpolation" should be "(x_1,x_2,y) regression"
 
@user202729 Never used it. No idea
 
CMP: Is your student in your country have to learn one of those ^ as first programming language?
@user202729 Yes.
 
@user202729 Yes... One of the following 3: C, C++ or Pascal.
 
(this is not the first time I talked about that, but last time it was in JHT and only Mr.Xcoder replied)
 
@user202729 Totally depends on the school and when you learn it. The community college I went to teachers C++ for beginners. But the popular uni teaches Java. And highschools teach Python
 
4:38 PM
@user202729 We learnt Python for 3 years, then the exam board removed the programming part of our exams, now we have to learn a bunch of theory in 3 months :/
 
So it depends
 
@user202729 I learned Pascal on my first semester in college, then C and then Java.
 
I just taught myself though
 
Nowadays the first and second semesters are Python, I believe
 
@DJMcMayhem "taught"?
 
4:40 PM
Hahahaha
 
Pascal ... ugh. I remember looking at it from examples in a book on solutions to polynomials.
 
Although it's possible to make C++ shorter (with using namespace std; and a lot of defines (overall longer?),
then it's no longer C++.
 
#define is your friend in golfing C/C++
 
4:55 PM
Just enabled the goatvoting options in theme settings... this is amazing! :P
 
@labela--gotoa gaots > ships
 
@labela--gotoa that question is the ultimate proof that Mathematica has every conceivable builtin ever.
 
shouldn't this be closed?
 
@Oliver Thanks! There's a javascript implementation also, but I do like C# as a language.
 
5:02 PM
@totallyhuman Why exactly?
I think this is not a serious contender btw.
 
nevermind
waaht
wait
 
TFW SageMath is winning a :/
 
We need some reposts...
Pro tip: Never force quit a decompressor while it decompresses an IDE xip.
 
(will it work now?)
yes
I just had to XD
I should revert it
 
@Mr.Xcoder Reposts of old questions? Or am I just being confused?
 
5:08 PM
What exactly are you talking about?
@Zacharý Yup, reposts of old questions.
 
@Mr.Xcoder WHich question, former or latter>
 
I made my name even worse now ._.
god dammit, TNB! Why you didn't change it :E
 
It changed it for me.
 
nevermind
 
@Zacharý It should be No original name here
 
5:10 PM
@baotofgaots Why? It's not a good username
 
@Mr.Xcoder Is that sarcasm?
 
You didn't see me, ok?
 
@Dennis do you know which function julia uses for repl output?
i.e. using primes, try to factor smth with factor
it will print a nice output
but when I use show or println to do so, it returns a function call type thing
 
5:13 PM
I used to know this, but I don't remember.
 
@baotofgaots Take it from someone who spent ages trying to find a good username and still ended up with this monstrosity, Soaku is a good username
8
 
@Dennis hm, ok. reading help pages seems to say display, but that formats my other string weird
@cairdcoinheringaahing yeah and boat of goats isn't
sincerely, the guy who is partially responsible for this cancer
 
yay I just got the badge for reading the tour page :D
 
grats
 
ಠ_ಠ you... haven't had it till now... and you have over 17k
:'-( The life is like a ride in a boat is gone
 
5:19 PM
@Mr.Xcoder account deletion probably took it away, idk
 
Account deletion?
 
holy crap this user posted a single question and capped day 1 of being PPCG user lol
 
Dennis is 11 answers away from getting the gold badge :O
 
@Mr.Xcoder ...yeah........?
 
also cc @Dennis
 
5:20 PM
idk maybe I just never bothered to read the tour page
 
@HyperNeutrino When have you been deleted?
 
@cairdcoinheringaahing Why is that grounds for ಠ_ಠ?
 
^
 
@Mr.Xcoder last june
 
dennis is cool who cares if he gets another shiny thing
 
5:20 PM
you made a post about me getting my deleted content merged back... ಠ_ಠ
^^
 
@HyperNeutrino ... What does that have to do with your About me?
 
@Dennis Corrected :P
 
@Riker Hadn't seen a link inside a ping before. Confused me for a second.
 
@Mr.Xcoder it doesn't. follow the reply chain.
 
@HyperNeutrino I know that
ಠ_ಠ yeah...
Sorry
 
5:21 PM
lol :P dw
I usually reply first-to-last instead of most-recent-to-least-recent
 
@Dennis heh
"oh hey dennis, here's a link to your profile in case you lost it"
 
also you actually noticed the boat thing? :o
 
Yup, and actually read it all
 
ooh cool :D wasn't sure people actually looked at my profile page :P
 
@HyperNeutrino Why is your About me just a ~?
 
5:23 PM
@cairdcoinheringaahing idk, i didn't have anything in particular i wanted to put in there but i wanted to avoid the (air of mystery) message
also today is the highest daily rep gain I've had since Nov 15 last year... ಠ_ಠ
 
nice
 
@HyperNeutrino And mine's the second lowest :/
 
CMC: what will happen in roughly 237 days?
 
o rip :/
 
(and no, not jst the date, what happens then :p)
 
5:25 PM
@Mr.Xcoder I'm glad I even got a rep change today :/
 
also I just realized that this is basically the derivative of my rep chart
 
@cairdcoinheringaahing Same here :|
CMC: Find a function that resembles my rep chart well
 
@Riker we will get our site design :D
 
exactly :p
 
5:26 PM
Holy crap, APL outgolfed Jelly: codegolf.stackexchange.com/questions/157664/…
 
@Zacharý well jelly is pretty bad at string stuff compared to other things
 
@Riker Wait, for real? Without checking a calendar, that's Nov 1st, isn't it?
 
^
and it's not like its' a huge amount
@cairdcoinheringaahing yes >_>
 
@HyperNeutrino The APL solution does not use strings
 
oh wait the challenge doesn't require string stuff. nvm i'm dumb
 
5:27 PM
and neither the Jelly one does
 
And it was Dennis of all people who got outgolfed (meme here)
 
no (as in pls no meme)
 
memes are dead for a reason
 
To be fair it seems to be an algorithmic advantage more than anything else
 
I won't insert a meme.
 
5:45 PM
How can I make an if in Mornington Crescent? AFAICS, you can only jump backwards
 
can I have some final feedback? codegolf.meta.stackexchange.com/a/14558/68942
(~2 months in Sandbox should be good :D)
 
It's a shame that Cards Against Humanity is so subjective. It would make for a hilarious KOTH :P
 
CMC: What will happen in <8 days?
 
Spring Forward
 
Closed as too localized.
 
5:47 PM
lol
 
@HyperNeutrino My spring break ends... :(
 
o :(
hm yeah same
 
@HyperNeutrino My mocks end :D
 
wat r those D:
 
Mock exams, prep for our final exams
 
5:49 PM
my spring break begins lol
 
@cairdcoinheringaahing oh okay i see
 
or wait no
 
I don't even know when my Easter holiday starts :/
 
oh man my break starts late this month D:
 
my spring break has nothing to do with easter :P idak why march break exists
(nobody has given the answer I was thinking of o_O all correct but still)
 
5:50 PM
What were you thinking of?
 
march 17th will happen
 
(waiting for more responses o_O I thought at least one person would get it but apparently it's too not well-known or something)
(and no it's not St. Patrick's Day, I don't really care about that)
 
Spring Break \o/
 
@HyperNeutrino It'll be a Saturday! :P
> The short form for this date used in the United States is 3/17/2018, and almost everywhere else in the world it's 17/3/2018.
 
(facepalm yes and it will also be the day before a sunday :D)
 
5:52 PM
Haha

Q: Scheduling Meetings

Dr Xorile[I am cross posting this from the puzzling SE.] I came across this problem in real life and thought it could be made into an interesting puzzle. I will enjoy seeing how my eventual solution could be improved! Here's the situation. There are 290 themes that need to be discussed. Eac...

 
why does ^ have upvotes and not closed
 
It's an interesting challenge. Maybe people upvoted it before reading all 200 lines :P
 
@HyperNeutrino PI DAY
 
@NieDzejkob 3/17 is not pi
 
5:55 PM
@HyperNeutrino <8 is 0, 1, 2, 3, 4, 5, 6, 7
