Luis Mendo

@Doorknob Thanks for deleting the comments here to avoid confusion

@PhiNotPi Sounds good :-) But, what do you mean by "sample P"? Isn't that what the Markov chain does by itself? Or is it a factory (transform P into f(P) for specified f?

Why does TNB not notify me?? I saw your message by chance

PhiNotPi

@LuisMendo well... normally a Markov chain gets asymptotically closer to P as you perform more trials... this is a perfect sampling method.

Luis Mendo

@PhiNotPi Ah, I see. What's the average required number of tosses per output?

PhiNotPi

I'm gonna try to figure that out... I'm trying to increase its efficiency right now.

Luis Mendo

01:11

@PhiNotPi Do you think the method could be extended to the Bernoulli factory problem? Generate f(p) from p, for some specified f belonging to a suitable family

PhiNotPi

Okay, I just polished up the algorithm.

  public int sampleSD() {
    while (state == 1) {
      next();
    }
    int count = 0;
    while (state == 0) {
      count++;
      next();
    }
    while (state == 1) {
      count--;
      next();
      if (count == 0) {
        if (state == 1) {
          return 1;
        }
        return 1 - sampleSD();
      }
    }
    return 0;
  }

for a regular, fair coin, this takes about 6 flips for each output bit.

  public int sampleSD() {
    while (state == 1) {
      next();
    }
    int count = 0;
    while (state == 0) {
      count++;
      next();
    }
    while (count > 0) {
      if (state == 0) {
        return 0;
      }
      next();
      count--;
    }
    if (state == 1) {
      return 1;
    }
    return 1 - sampleSD();
  }

^ slightly nicer version

Consider a coin that has a 0.3 chance of being heads if the previous flip was tails, and a 0.4 chance of being heads if the previous flip was also heads.

In this case, the coin will be heads 1/3 of the time in the long run... but the flips are not independent, and the distribution of any particular flip isn't perfect.

This algorithm is able to use that coin to generate a perfectly independent 1/3 probability, using 6.667 flips of the coin on average for each output bit.

Wikipedia:User access levels

A contributor's ability to perform certain actions in Wikipedia depends on their user access level. This is determined by whether the editor is logged into an account, whether the account has a sufficient age and number of edits, and what additional rights ("user groups", also called "flags" or "bits") have been assigned manually to the account. Everyone is able to read Wikipedia. Unless they are blocked, they may freely edit most pages without the need to be logged in. Being logged in gives users a number of advantages, such as the ability to create new pages and the ability to track one's...

Semi-random question: If you go to my chat profile, how many rooms does it say I own?

DrMcMoylex

Hahaha, I can self-star (not pin) messages in rooms I own

El'endia Starman

03:35

I'm not sure this is entirely clear, but my message about kicking people for posting faces was largely reactionary. Two chains of faces in 10 minutes, and I wanted to be sure there wouldn't be any more immediately. That it's now got 10 stars surprises me, and tells me that I was unaware of the feelings of other people on the matter.

Downgoat

I just realized I read the emoji faces message wrong :|

I read as "I will kick for posting faces"

Hm, I guess it's up to interpretation

do you interpret it as if you post nothing but faces, or if your message was posted with nothing but faces

Calvin's Hobbies

@DrMcMoylex The "gaotspek" stuff annoys me a lot more than any face stuff.

DrMcMoylex

I would definitely agree with that. (Sorry Downgoat)

Downgoat

I am guilty of setting a bad example with all these "gaotspek", but my typos are honest mistakes.

wat

@Calvin'sHobbies am i the only one who doesn't mind gaotspek?

Downgoat

03:38

"y u do dis ;_;"s are obvious exceptions but those are jokes

Dennis

@wat Yes.

El'endia Starman

Yeah, I don't want to just kick people willy-nilly for posting a face or two, even if they're the sole content of messages, because they can be a valid way of expressing one's reaction or emotion. That said, I do also want to keep the noise level low, and ASCII faces can easily be accompanied by words that clarify the intent behind the face.

DrMcMoylex

@Downgoat No offense, but I'm calling bull on that

Downgoat

hey that was long time ago :P

Dennis

@wat Floating IPs may be an option, if your provider has them. I'm not sure what protocol Minecraft uses. If there are no redirects, the only remaining option would be tunneling, which means that all data from and to the Minecraft server would have to pass through the webserver.

El'endia Starman

03:40

There's another issue I've identified: there's no body language to pick up on here. I don't think this has really been explicitly pointed out yet, but people chatting can't tell how spectators feel. How many people don't chat because the content, particularly the noise level, of this room at times is irritating and aggravating?

wat

@Dennis Oh yeah, floating IPs! I completely forgot about those

OMG thanks!!!!!

Downgoat

though tbh i'm not talking in "gaotspek", that one message's typos promote the connotation of confusion within it, which is why

@ETHproductions that is true

though I did modify my avatar after to fit the -1

@wat I don't know much Ruby, but is it either self or this?

Downgoat

03:55

not sure why i didn't try to resize the -1

ETHproductions

@wat Actually, I think it's probably not possible to do that. It's definitely not in JavaScript

You'd have to do str="hello world";str.rjust(str.length*2)

Downgoat

Btw, anyone have some feedback on this cheddar feature idea:

func head(array, endIndex
    where #end -> array.len - 1
    where #mid -> floor array.len / 2) {
    return array.slice(0, endIndex);
}

lets you do:

head([1,2,3,4], #mid) which outputs [1, 2]

ETHproductions

That's a pretty new idea to me... I'm gonna have to think about that before I can really provide feedback (after all, TC39 doesn't approve features at a glance ;P)

Downgoat

TC39? This is cheddar not JS :P

or was that a joke idk

ETHproductions

Downgoat

04:00

something irks me about that

I can't concentrate on the actual feature

I'm distracted by the fact that head should be of type [a] -> a, but here it's [a] -> [a]

ETHproductions

The "chained" where statements bug me, personally

They're not chained, obviously, but they look like they are.

Zwei

something feels very ruby about this to me, but I don't know why because I've personally never used ruby

ETHproductions

@Downgoat So is #end sort of like Ruby's :end (i.e. a symbol)?

Zwei

that's it

Downgoat

04:09

@ETHproductions yeah, but it's defined in the function

meaning you can pass a number or #end

it also works with strict typing unlike symbols

ETHproductions

Now that I've thought about it, I like that idea very much. The one thing that irks me is the where syntax, as mentioned above

it seems like it'd be amazing if I learned how to use it though

Dennis

@wat Curious, why can't you just run webserver and Minecraft server on the same VPS?

wat

@Dennis my webserver is already slightly overloaded. also, it only has 512MB RAM and my MC server is modded

ETHproductions

A month ago, I spent a while thinking about what "novel" language features I would have in my ideal all-purpose language... and looking through the Ruby showcase, I just noticed that Ruby already contains at least half of these, and a ton more I hadn't thought of :P

Maybe I should learn how to use Ruby

Dennis

04:17

@wat Not sure what modded refers to. Temporarily resizing the VPS while MC is running should add more RAM, assuming your provider allows this.

@Dennis I have many mods installed on both the client and the server, which both add more RAM use and CPU usage. Improves the game a lot though.

Well, there's that one, but I thought there was already one before that... maybe I'm just remembering wrong

Sesos does way more than mapping characters to 3 bits though. Long chains of + or - are compressed quite effectively.

And Jelly does way more than that

Not exactly related to brainfuck though.

ETHproductions

Every language is derived from BF.

ETHproductions

Yes, they're all just BF travelling into the past/future with new instructions/syntax.

Even ignoring dates, functional programming langs are so fundamentally different from bf that they can't really be compared

ETHproductions

Gosh, sometimes I wonder if an esolang was created just so it can be posted in the showcase...

poi830

Is an answer valid if you can't prove whether or not it terminates?

For example, if it terminates if and only if there is an inconsistency in ZFC

Zwei

for what challenge?

poi830

in general

obviously i dont have an answer like that

Zwei

hm

ETHproductions

It really depends on the challenge, but I'd say generally not

Zwei

04:47

well, let's assume that there is a challenge in which you have to count the number of times the collatz cycle is applied to a number until it hits 1

the trivial way to approach the problem would me to make a loop, and count as you keep applying the function to the number

ETHproductions

In that case, no known algorithm will terminate for every input

So the problem lies in the challenge, not the answer.

Zwei

however, as it is unproven whether or not it always lands on 1, it is as of right now unproven if the algorithm will terminate

in this case, I'd say that a program with indeterminate halting status is acceptable

because it's required

ETHproductions

Yes, exactly.

However, for most challenges that translate input (or nothing) to output, it would be stupid for an answer to possibly not terminate on a valid input

Zwei

valid input

poi830

It seems possible you could have a problem where there is an algorithm that is known to terminate. If you had a different algorithm that you could not prove terminated, but for which there was not a a known case where it did not terminate, would it be acceptable?

It seems like it wouldn't be acceptable, but I'm not entirely sure.

ETHproductions

04:51

Hmm...

Zwei

I lean towards not acceptable there, but perhaps this warrants a meta post?

ETHproductions

That's right on the fine line between acceptable and unacceptable... a meta post might be necessary

There may already be one

There's this: meta.codegolf.stackexchange.com/q/4782/42545

poi830

That's where I got the inspiration for this question.

ETHproductions

Oh, haha

Geobits

I think it would be better to have an example. If it's never come up on the site before, it's harder to answer than if there's something concrete to look at.

And if nobody can come up with an example, it doesn't matter so much ;)

poi830

04:55

I'm not sure there's an existing example, as this is a pretty esoteric situation, but now I'm slightly tempted to try to make one.

Zwei

this question is asking about printing the answer and then entering an infinite loop with no output afterwards

however, the question being asked here is if an algorithm with unknown halting status is allowed

Doorknob

@Zwei well, the meta post is about submissions that demonstrably do not terminate. The "print and then loop" is just a contrived example

poi830

This seems analogous to an answer that seems to always produce the correct output but is not proven to. Is there a meta post about that?

ETHproductions

Obviously answers to this challenge would be exempt, whatever the ruling

Zwei

should I start writing up a meta post, or should I let someone else do it?

I'll probably let someone else do it, as it's 11 pm here so I'm bound to make a few miskates
