Hey @Adám, I read that screwdriver story on TNB, that was funny hahahah

@J.Sallé :-D

@ngn How do I find the parity of an integer in K?

@Adám x!y is "residue"; x must be a positve int atom

@ngn That's what I tried, but I got type error in K. However, it works in oK.

@Adám it could be a recent change in the language

@Adám what expression did you try?

@ngn 2!3

@ngn Maybe. Mine is from Oct 11.

@Adám in this particular case you can convert to boolean and then back to int :)

@ngn huh?

i$b$3 / or something like that

  b$3
'b
  [0]  b$3
       ^

@Adám though I'm not sure if convertion to boolean would just take the last bit or do x!=0

@Adám argh

@Adám where are my backquotes?

@Adám this chat is eating them

@ngn double them

@Adám ``b$3

@Adám i$b$3

  i$b$3
'b
  [0]  i$b$3
         ^

  `i$`b$3
'type
  [0]  `i$`b$3
            ^

@Adám huh, now we have to guess...

@Adám perhaps "b"$3 ?

@ngn yup.

@ngn Whoa, lots of types:

  "bcdefhijmnt"$3
(1b;"\003";2000.01.04;3e;3f;3h;3i;3;2000.04m;0D00:00:00.000000003;00:00:00.003)
  "uvz"$3
(00:03;00:00:03;2000.01.04T00:00:00.000)

what you want is probably "j" - long int

@ngn It came up as I was solving:

@Adám if you're allowed to take a left and right argument, you can use + instead of +/

@ngn I realised that, but I doubt it, as it is really a single item; a position name.

@Adám actually, "left" and "right" probably don't make sense...

@Adám I meant: ( darklight 2!+ )[x;y]

@Adám (with backquotes before "dark" and "light", of course)

@ngn What is that, and how is that an improvement? My solution is much shorter, no?

@Adám your solution could be just the thing in parens

@ngn Right, ok, but for the reasons stated I refrained from that.

@Adám does Dyalog APL impose limits < 2¹²⁸ on recursion?

for example is this answer valid?

of course I can't test whether it can really count up to 340282366920938463463374607431768211456 or more, given enough time and memory

@EriktheOutgolfer No, tail recursion is free forever.

@Adám then my answer should be valid, yay my first APL outgolf :p

@EriktheOutgolfer Yes. Good job!

tw

@ngn tw?

@Adám "tw?"?

maybe "that works"?

@Adám huh, not intentional. One of my control keys is causing trouble.

@Adám sorry

oh well :p

@EriktheOutgolfer Turned out to be "that doesn't work" (the control key).

@Adám the human mind always looks for patterns and meaning, even in random noise :)

he probably wanted to open a new tab and had a shortcut for a site starting with w and wanted to visit that site ;p

@EriktheOutgolfer more likely ctrl+w to close this tab

@ngn thmalfpam, eirn? That doesn't make any sense!

@ngn no

ctrl+t = open new tab

w + enter = go to some "w..." site

@Adám have I said that?

unless the t was accidental too

@ngn you didn't get it

@EriktheOutgolfer scratching my head...

@ngn in ngn's intelligent text i assumed little secrets

@Adám what is "thmalfpam, eirn"?

it's actually very obvious

@EriktheOutgolfer Let him suffer ;-)

@Adám sure, let's see how much time it takes ;-P

@Adám I'm expecting a cut and paste to room "Unsolved Mysteries" any moment now :)

⍞←⎕TS

@Adám 2017 11 14 19 12 37 472

@Adám is that a clock for me to solve the mystery? :)

@ngn Yes. Well, your start time.

@ngn of course

@EriktheOutgolfer well, I can answer immediately

why not show off how fast you are at solving mysteries? ;-)

@EriktheOutgolfer thmalf flaghn rhorotorphle rhan, khopf?

@EriktheOutgolfer cthulhu fhtagn rlye!

?

this one is easily solvable: The Call of Cthulhu

@Adám ? :)

@Adám I saw random noise and I responded with (well, almost) random noise :)

@ngn What I wrote was by no means random, so you have not solved it yet.

@Adám you and Erik guarantee that?

yes I do guarantee that

@ngn Absolutely. I even gave you a tremendous hint.

@EriktheOutgolfer ok, starting to read carefully again...

@Adám and I gave another too

@EriktheOutgolfer initial letters?

⍞←⎕TS

@Adám 2017 11 14 19 22 23 255

@EriktheOutgolfer Where?

@ngn congratulations!

@Adám from my previous line

@EriktheOutgolfer I don't get it.

⍞←⎕ts

@ngn 2017 11 14 19 24 14 498

@Adám only thing I can say, it's actually very obvious :) (and ngn found out anyways)

@EriktheOutgolfer I most definitely did. The clock is now ticking for you, @Adám :)

@ngn for what

the random chars you posted above?

@EriktheOutgolfer he said "I don't get it" :)

oh for my clue

also it's a bit unfair since you added seconds unfairly to Adám ;)

@EriktheOutgolfer never mind... he's probably not paying attention right now anyway

@ngn @EriktheOutgolfer I am, but you've completely lost me. Did EtO provide a clue for ngn?

maybe it's too vague

@Adám if he did, I didn't get it. He only said it was "obvious".

@ngn I'm trying to find the clue that EtO provided. Maybe there isn't one?

I don't think it was for you @Adám

@Adám maybe it's the fact that he said it's obvious

Oh well, nothing for me to find. No wonder I can't find any. :-(

but anyways
