The Nineteenth Byte

1:03 AM

This is better

You should still specify the centering on the texts

hi

i mean, how do i specify that

Well when the text is an even width you can't perfectly center anything

I have a quick little brain teaser on Ruby. Figure out why this returns 2047.

So you need to specify if it will default left or right

1:07 AM

@SimplyBeautifulArt without looking, is it exponentiation-xor confusion?

@DestructibleLemon No, it's completely syntax incorrect.

Just look at the parenthesis

and hardly any of the letters seem meaningful.

weird digraphs I would know if I did ruby?

@Whe

2

maybe its this thing that make left to right

@WheatWizard So default left?

1:09 AM

I don't know, you haven't said in your challenge

:-)

:^)

@SimplyBeautifulArt ok its a rtl thing which is why it happens. cheap trick yo

@DestructibleLemon :-)

Even then, I'd expect it to return more than 2047

Also middle of the screen is ambiguous because the screen is an even height, you should say 3 from the top.

1:12 AM

Hm, now only if I could save one byte...

done @WheatWizard

how do i delete it

I have a good idea for a programming language

It'd be called "GITHUB IS NOT A CDN"

It uses a JSON file hosted on GitHub as its 'scripts' in another programming language

Then they are called with an eval from that programming language or something

If there's an interpreter, then I can write it.

There is an interpreter

But a theoretical one is just as easy...

@HelkaHomba Use like a fake third/fourth-level modifier key that does macros (with AutoHotKey or something?)

@Mego just saw your random integer sequence challenge. that was actually my first idea for Random Golf #8 before I turned it into codegolf.stackexchange.com/q/120472/8478 :)

Anonymous

@MartinEnder And to complete the circle, RG8 is what inspired my challenge.

I figured :D

but yeah I ended up not doing it because I had trouble specifying the requirements on the randomness. with a string it seemed less weird to limit the possible movements of value to a finite range, so you can actually talk about positive probabilities.

As you can see, I'm having a bit of trouble too.

My probability and statistics knowledge mostly comes from one class in college that I didn't attend lecture for as much as I should have

@MartinEnder Did you see my question about your random challenge?

May 13 at 22:15, by feersum

@MartinEnder Would a program that takes two number j, k (from 0-19) as a seed, prints out the first j items unchanged, and after that reads in batches of 20, prints the last k items of the batch, and then prints the first 20-k be a valid answer? If not, why?

@feersum Ohhh, I completely forgot to respond to that. I was thinking about adding some specification about statistical independence, but that's tricky as well. I guess I'd just go with this randomness is not equivalent to something like a Mersenne Twister.

That's not a very clear definition... what makes an RNG "standard"?

Surely there are RNGs (or algorithms billed as such) at every point on the popularity spectrum.

6:33 AM

yeah, I'm not a huge fan of our "standard definition" of randomness either. but I'd say in your case there's really no randomness in any standard sense of the word.

do you have an idea how to specify it properly such that cases like this would be clearly disallowed?

Actually, I'm not sure my answer even fails that definition.

I only generate 1 random number with my RNG.

Thus it is equivalent to MT, or many other standard RNGs.

@MartinEnder Scratch that, your question doesn't actually say than anything should be "random" anywhere.

It only talks about probabilities.

Were I to write a random question, a random bit stream would be part of the input.

but isn't the fact that we're supplying a seed specifically the problem that allows your loophole?

without giving a seed, it's clear that you need some form of randomness because otherwise you can't satisfy the probability requirements

Not really.

You could still do something that generates only a single random number.

What seems to be missing is a requirement that the probablities be independent.

Actually, that may be too strong.

yeah that's why I didn't specify it. I mean it's virtually impossible with infinite sequences and finite-period RNGs

Well if we're going with the definition of an RNG as a magic box that's defined by cultural considerations rather than mathematical properties, then that requirement can be satisfied by assuming the RNG is magic.

6:45 AM

right, but then if people take a seed and implement their own RNG, how magic is magic enough. that's exactly the issue, isn't it?

Hmm, maybe a weaker (but bizarre) condition for your question could be that any number that the program has already consumed from the input stream must have a positive probability of being output.

Is it just me or did Chrome just start unloading inactive tabs and then just loading the page from the URL again when you switch back to it

man, haxe is a cool language, but it has some really stupid design decisions

I don't know why it is so but the preamble at the start about different words is really amusing

Doesn't every language have some really stupid design decisions?

Haxe's data streams have a function called readAll() which is literally unusable

because every function that reads from a data stream throws an Eof exception when it reaches the end of the stream. readAll() will always reach the end of the stream, and thus will always throw an Eof exception. If it throws an exception you can't get it's return value, so it's completely useless

11:31 AM

you can still use it to read - and discard - all of the stream :-D

@JanDvorak Almost. I don't think K has any.

@Mayube exception handling anybody?

@Adám I dispute K's design decision for an extremely spartan documentation

If your language documentation fits entirely on a single page in your browser ... something's not okay.

@JanDvorak That's not a language design decision.

@JanDvorak Have a look at github.com/JohnEarnest/ok/tree/gh-pages/docs

@EriktheOutgolfer if you handle the exception, you can't get the function's return value. A function doesn't return if it throws an exception

11:41 AM

I mean the function's definition should have exception handling inside

K is utterly unreadable to the uninitiated despite not being a golfing language. That is a design decision :-D

go one letter back

right, but it doesn't, because it follows what the docs say

@Mayube out parameters?

doesn't take any params

plus I'm not sure Haxe even has out params anyway
