Sherlock9

The min_by part keeps returning Fixnums for no good reason

Or at least none that I can see

@AlexA. Look at the gist again. Look who uploaded it.

Doorknob

@Sherlock9 Well it ends in size, so I would be surprised if it didn't

@Mego BRO I DONT HAVE TIME 2 READ ALL THE THINGS YOU GUYS POST

Sherlock9

6:06 AM

I was trying to write x.min_by{|m|*foo*.size}

Doorknob

Right, and size returns a fixnum

Sherlock9

Fantastic

Wonderful

Help

Doorknob

haha

What do you expect it to return?

Sherlock9

The smallest array

Doorknob

oh, yeah, it's min_by, not map; I'm an idiot

Sherlock9

6:08 AM

I figured it would be like, map everything in x then return the smallest array

@Calvin'sHobbies I don't know if you're the downvote on my Meta answer, but the OP stated that the goal would in fact just be "Recreate the mona lisa" which is too broad. Either way your answer's better (at least for an alternative other than not doing the challenge)

Doorknob

@Sherlock9 That's what it should be doing

Sherlock9

Well, I'm the one running into walls, so

YEAH it really should be doing that! ಠ_ಠ

Hmm. Okay, first I'm trying to comprehend what exactly the code is supposed to be doing

@Sherlock9 What is the a variable in your code supposed to mean? It's only referenced twice, and both times before it's defined O_o

Dennis

6:15 AM

Unless I take the GS2 approach and implement a 2spooky4me built-in, I don't see how that could be beatable.

Sherlock9

@Doorknob Oh horf I didn't post the whole code

a=->n{n<1?[]:a[~-n/3]+[-n%3]}
f=->x,y{x.is_a?(Array)?(x==y[0...x.size]?y[x.size..-1].map{|m|["SE","SW",?N][m]}:x.min_by{|m|[["NW","NE",?S][m],*f[x[0...x.rindex(m)],y]].size}):f[a[x],a[y]]}

Doorknob

oh, ok

Sp3000

@Dennis Hmm when you said you had a three-byte "spooky" that wasn't what I had in mind :/ I thought you had <get-word-from-dict> <index in base 256 in two bytes>

Assuming 65k most common words are in the dict

Dennis

Yeah, it's a bit more complicated that that. There are 248,298 words in the dictionary.

Doorknob

@Sherlock9 I still don't really understand what either the Python or the Ruby means, but I think I can figure out why the min_by portion is returning fixnums

Sp3000

6:17 AM

Well, basically I mean I didn't expect delimiters :P

Doorknob

First, you call f with two fixnums (initial input)

Then those both get passed to a

Sp3000

(also where does the "me" come from?)

Doorknob

a returns an array of fixnums

Then these arrays of fixnums get passed to f

And then you call min_by on the array of fixnums

Therefore, min_by returns a fixnum

Dennis

@Sp3000 Ooh, now I get it. That's a brilliant idea!

Sherlock9

@Doorknob But I'm calling min_by on the size of each array of fixnums

I think

Dennis

6:21 AM

@Sp3000 “×¥X“ŀ`» yields the array ['spooky, 'me']. ×¥X encodes spooky, ŀ encodes me.

Sp3000

Yeah... my general reasoning is that get-word-from-dict should be useful if you only need a single word or two, e.g. adding "meters" to the end or something.

Doorknob

@Sherlock9 You're calling x.min_by; therefore, some element of x will always be returned

It's basically x.min with a custom predicate for defining min-ness

Sherlock9

Well, hell

Sp3000

me is 1 byte? Hmm nice

Sherlock9

That's a good point

Doorknob

6:22 AM

What are you trying to get it to return?

Sherlock9

Zach Gates

Sherlock9

I'm going to literally run into a wall now ಠ_ಠ ಠ_ಠ ಠ_ಠ ಠ_ಠ

Doorknob

Are you trying to do something like x.map{|m|...}.min?

Sherlock9

@Doorknob The [["NW","NE",?S][m],*f[x[0...x.rindex(m)],y]] I was trying to create

Which I now flipping realize. That if I wanted to create it. I . REAAALLY should have placed it better

Doorknob

6:24 AM

Oh, so you're trying to find the [[...]] with the minimum size?

Sherlock9

yep

Doorknob

x.map{|m|...}.min_by(&:size)

Dennis

@Sp3000 Not quite. (Stupid mini markdown.) It's ŀ`.

Sp3000

Ah.

Sherlock9

@Doorknob Ooh that &:size is a cool trick

Doorknob

6:25 AM

@Sherlock9 Yeah, prefixing a Symbol with & calls to_proc on it, so foo.min_by(&:size) is basically foo.min_by{|x|x.size}

Sp3000

@Dennis Any ordering of commonality of words? Trying a few random two-bytes and I don't know most of these words o_O

xxx becomes -T aarrghh

Dennis

@Sp3000 Words are ordered alphabetically and split into dictionaries of short (5 letters or less) and long words. For example, doorknob is at index 56926 in long, so we can encode it as 6 × 56926 + 1, convert to bijective base 250 and look up the corresponding chars of Jelly's code page. For Doorknob, we need to change case, so it's 18 × 56926 + 2.

Relativity of simultaneity

In physics, the relativity of simultaneity is the concept that distant simultaneity – whether two spatially separated events occur at the same time – is not absolute, but depends on the observer's reference frame. == ExplanationEdit == According to the special theory of relativity, it is impossible to say in an absolute sense that two distinct events occur at the same time if those events are separated in space. For example, a car crash in London and another in New York, which appear to happen at the same time to an observer on the earth, will appear to have occurred at slightly different times...

@Mego No, I've been looking at it. If the iterable,n,fillvalue=[1, 2, 3],5,0 then you end up with [(1, 2, 3, 0, 0)]
