A new addition to the Dyalog Duck Collection ... thank you @mkromberg for bringing this little duck all the way from India

@Adám why does (⊢×*)⍣¯1⊢1 domain errors?

@Uriel Because you're using 14.0?

⍞←(⊢×*)⍣¯1⊢1

@Adám 0.5671432904

Hmm, yeah I did use tryapl

@Adám yet it gives only one solution of 2 for ¯0.1

@Uriel Can you show me what you mean with ⍞← ?

@Adám nevermind, I didn't read fully the specs

Or did I? I'm regarding codegolf.stackexchange.com/questions/148865/…

⍞←(⊢×*)⍣¯1⊢¯0.1

11:14 AM

@Uriel ¯0.1118325592

There is one another solution

⍞←(⊢×*) ¯3.57715

@Uriel ¯0.1000001487

@Uriel So? It can only give you one:

⍞←×⍨⍣¯1⊢25

@Adám 5

⍞←×⍨¯5

11:16 AM

@Adám 25

11:31 AM

@Uriel Wonder if the secondary solution can be calculated from the primary.

@Adám that's very outdated, don't count on it atm

I'm slowly making a new one behind the scenes

@EriktheOutgolfer Btw, I've finished the first version of my new programming language, Stencil.

> van Neumann neighbourhood

:-D

@EriktheOutgolfer Thanks, fixed.

btw @Adám how does Stencil work? how does it get the dimensions of the neighborhood?

J. Sallé

G'morning people o/

12:56 PM

@EriktheOutgolfer If no size is given, size 3 will be used in every dimension.

@Adám but how do you give a size?

the readme.md is kinda unclear

@EriktheOutgolfer As right operand, which is "Arguments" on TIO.

hmm

so I guess if I want a 4×5 neighborhood I'll have to count space+4+space+5?

also

tio.run/#stencil

@Adám yeah no TIO yet

@EriktheOutgolfer You mean score count? No, you add two arguments; 4 and 5. That's only two bytes ;-)

in talk.tryitonline.net, 2 hours ago, by Adám

@Dennis Can you add Stencil?

@Adám huh? I thought you count the spaces...like stencil program 4 5

@Adám I'm talking about the present rn ;-)

1:03 PM

@EriktheOutgolfer But you never write Stencil program 4 5. Using the operator in APL, you'd write 'program'Stencil 4 5 but I think consensus is to not count spaces (or dashes) for various options and flags in TIO.

@Adám oh so you don't invoke it like dyalog stencil.dyalog program 4 5?

J. Sallé

Hey @Adám, do you have/know of a reference implementation for SHA256 or AES256 in APL? I'm curious how would hashing/encryption be done in it :p

@EriktheOutgolfer No, have a look at the TIO wrapper.

@Adám wow, looks like it makes some dangerous assumptions

then again I don't know how to solve

@EriktheOutgolfer Like what?

@EriktheOutgolfer Solve?

1:09 PM

export DYALOG=$(ls -d /opt/mdyalog/*/64/unicode | tail -1)

@Adám this

@EriktheOutgolfer That's TIO specific. No way around that.

@noidd @kaepora We do love a challenge - yes we can do it in 123 characters: KSA←{S⊣⍵∘{S[⌽p]←S[p←⍵,j←256|j+S[⍵]+⍺[⍵|⍨≢⍺]]}¨S←⍳256⊣j←0} PRGA←{(S i j)(S[256|+/S[j i]←S[i,j←256|j+S[i←256|i+1⊣S i j←⍵]]])} Try it online: https://tio.run/#%23SyzI0U2pTMzJT///qG@qp/@jtgkG/72DHYF0dfCjrsWPerc@6phRHRz9qGdvQSxQNDi6AEgChXWygLSRqVlNljZQtndrrPaj3l0gRs2j3hWPOhcBebGxtYdWBIOVbwaqBBoH0mNQyxUQ5A62QSNYIVMhS1MjOBpkkLZ@cHSWQibElkwU8zOh7ExtQ6ApYF0QV8TGxmrW/v9fXFKUmpgLFAI6XQHokVDnYAV1v8SUzFwF7/yk1Mzi4sxHDf3qXBB1XBrFmXnZYKu9gXpArlGAyCgYKBhwAcUVvPGoAYpRVw0A
