The Nineteenth Byte

@AshwinGupta On a scale of 1 to 10, I'd say it's a 2. Maybe a 3, depending on the language.

Darn

this is just embarassing. I spent like 1/2 hour on an answer then just gave up.

I couldn't figure it out.

Don't be embarassed!

Just the logic part of it.

Not even the code part, I just couldn't get the logic. Couldn't wrap my head around it.

@AlexA. thanks. Its just that I feel like I should be able to do that.

> Essentially, what this code does is keep a running total with +1 for each [ and -1 for each ], keeping track of the maximum value reached, outputting that maximum at the end.

6:08 AM

Oh well, its late, I'll try again tomorrow. Maybe I'll have better luck then.

^^ explanation for my Minkolang answer to the question.

@AshwinGupta That happens to the best of us. There are some challenges that I don't even attempt because I just can't comprehend it.

@El'endiaStarman intresting, I actually was doing exactly that but I wasn't decrementing for each ], I was resetting to 0

@AlexA. yeah but the ones that you don't comprehend are probably like super-complex.

Anyway I think I know what I did wrong now thanks to Starman

Nah.

If you're comfortable with recursion, I thought my original approach to the problem was fairly easy to understand as well

Well you know what they say: to learn recurssion, you must first understand recursion.

6:11 AM

XD

or something to that effect. IDK I saw it on the internet once.

I am fine with recurssion. Ill check out your answers.

Normally I attempt the challenge myself before looking at the really good answers because otherwise I feel like I cheated. This time though I'm lost so I'll give yours a look.

Okay goodnight everyone

I don't consider it cheating. Often there are lots of good ways to approach a problem.

G'night!

Good night!

@El'endiaStarman thanks for explaining the logic I think I get it

@Katenkyo standard library functions totally count!

@Katenkyo which is to say, for arrays of integers in the range 0<x<256, you can find its length with strlen()!

@quintopia I didn't know about that Oo

is it because it assumes that integers can be used to encode some string on more than one byte/char?

@Katenkyo basically it starts at the given char * pointer and goes byte by byte looking for a 0, and returns its index.

@quintopia Wait, wouldn't it stop at the second byte then?

so just make sure your array ends with a zero and you're good

2:27 PM

If your first integer is 20, the next three bytes will be 0, right?

Assuming LSB >_>

...it needs to be a byte array man

11 mins ago, by quintopia

@Katenkyo which is to say, for arrays of integers in the range 0<x<256, you can find its length with strlen()!

integers in the mathematical sense. not int_t

I took that as int_t, sorry ^_^'

Then yeah, that'll work =)

Right, strlen won't work with an array of int >_<

@Roujo I assumed it was int_t too

2:31 PM

Or maybe it will. It's been a while.

it won't

I knew for the byte array, because the difference with a char is only semantic

anyway, i think there are libraries out there that implement arrays which track their own length. right?

@quintopia technically, as Lua can be pretty much used as a c library, of course

but I think there's thing dedicated to do it, yes

@Katenkyo so lightweight!

2:35 PM

@quintopia It has a very small compiler :p

you can do it easily yourself with a handful of macros and a struct

it sure is shorter than importing 23k lines of code ^^

Q: Convert English to a number (but all by your own)

hell, if you make the array the first element of the struct, you can even use normal array indexing on it

@VoteToClose I don't know if it's just the timing. I can't figure out what the "fun/interesting" part of the challenge is supposed to be, tbh. If it's fetching and parsing html, then it's been done. If it's shuffling without builtins, it's been done. If it's formatting the links in the output, it's been done. It just feels like a task to me, with too many disparate steps to be fun.

Not trying to speak for everyone, obviously. Just figured I'd give some feedback.

@MartinBüttner an empty from pattern in Retina (e.g. T``abc`.) is a NOP? it might be useful to include all chars in that case. Alsohow would you define any char ([\s\S]) in the from or to part of the transliterate mode?

I'm used to the SEGMENTATION FAULT in C... From the moment I started using pointers, each time I tried to use array the "normal" way, it was printing "SEG_FAULT"...

So I kept using pointers like int*** in the end...

@Geobits we could make a webcomics with these transcripts x)

But, why does it always start by "I'm not sure ..."? Did you feed him only sentences of this type?

3:28 PM

It's interesting to me that when it's confused, it chooses something that clearly indicates confusion. Not sure what that means, if anything.

@Katenkyo No, it has the full chat transcript (~500k messages), minus anything with links.

I like that it carroted my trolling comment though. Nice touch :D

@Geobits so it evolved to not be sure of anything until it will be able to understand it? Oo

And gave you a smily face when you said you were leaving him alone ^^

Dunno. It could be a big, really stable coincidence. I have no idea why it says that so often.

@Geobits Thanks for keeping us updated. Is this part way through processing still?

@trichoplax Yes, it's at step 19400, perplexity 31.

The original dataset/program I stole the idea from used 22M phrases and 340k steps (to get single-digit perplexity), so it's interesting seeing incremental progress.

@Geobits Maybe when it will have termintated the process, we will be able to understand how it decided to keep that

3:36 PM

Oh, it won't "terminate" really. It saves a checkpoint every 50 steps. So to see where it's at, you just run it with the latest checkpoint data. It will keep going until you terminate it yourself.

I don't know the format of the data, though, so I'd have to reverse engineer the checkpoints to get anything useful.

Oh, so 40k is just what you're aiming to let it run for, not a final goal?

I wonder if it will get to a point where you can run it against itself...

Yea, I can let it run for a week or two if I want to. My computer isn't usually heavily tasked, so it runs quite fine in the background.

Of course, anyone here with a stack of GPUs lying around could do it much faster. I didn't think my integrated graphics chip would help much, so I built it without GPU support at all. Gotta work those cores somehow.

@Geobits Some answers will choose to use the YouTube API, which we haven't done before.

I just spent a half hour trying to figure out how to return the name of a variable and put it in a printf statement before I looked on S/O and saw that you can't do that

^ Done that.

@Eridan What language? =)

@Roujo Java

4:12 PM

Specifically for Java, because I didn't want to declare a .getName() method and a name string.

@Eridan A couple of days ago, someone asked how to do this in Python.

@Eridan Ah, okay. Been there too. ^^

@Zgarb Consensus was "what are you doing"

@Eridan I think Java 8 has some libs for this. Lemme look up where I can fill in the required [citation-needed].

I think it was a legit use case in the end, though

@Roujo But there was a partial answer eventually.

Something horrible with globals.

4:13 PM

Come to think of it, I'm not sure when you'd not know the name of the variable you're using.

@Roujo Print it to the command line. ;P

String foo = "";
String fooName = "foo";
problem solved.

@VoteToClose Can you give me a snippet example? I'm just seeing this in my head:

It's either duplication of code or reflection, and I choose duplication of code

var foo = 2;
Console.WriteLine("Value of {0}: {1}", foo.Name, foo);

At which point you pretty much know that the name of the variable is "foo"

4:15 PM

I'm trying to write a class with no tester that returns the name of the object, which isn't working

So why not just inline it.

I'm probably missing something =P

Why wouldn't you just write Console.WriteLine("Value of foo: {0}", foo);?

Exactly

Because it can be any object passed to this class

he's trying to do a generic method I think

Who cares? As soon as you pass a variable, it changes names

4:16 PM

@Katenkyo Can you do it the other way around? Can you get the object from the string name?

Is it possible to search for an object of a specific type by passing the name of the object as a parameter to a method?

@trichoplax in Java, yes

So you'd want to know the name of the variable before it was passed into your method?

@Roujo Don't you usually know that? print(x) <- I know my variable is called x

using reflection, you can even use strings to do everything (even running a method in a class you created during run time)

4:17 PM

@Roujo No just brute force all possible names until it matches the variable you passed in.

This is for a golf, right??

@Calvin'sHobbies if I iterate over lots of variables, the name it isn't relevent

This sounds like a classic XY problem. There's surely a better way to get to the ultimate goal.

2

Here's the method I have:

System.out.printf("Information about the robot XXX \nLocation: (%d, %d) \nFacing: %s \nBeepers: %d", xCoordinate, yCoordinate, currentDirection, beeperCount);

and I'm trying to replace XXX with the name of the robot, which would be defined in the constructor Robot foo = new Robot( \* *\ );

anyway, Have to leave, good luck :)

@Calvin'sHobbies Well yes, that's my point.

4:19 PM

Then give your robot a name string and use that.

^

^

^

It'll be faster than using reflection, too.

Most probably

Could just be a random string or its mem address

4:19 PM

So an example would be Robot foo = new Robot("foo", /* */);?

Robot foo = new Robot("Foo", /* */);

Who names their Robot anything other than rob?

Then you can call foo.Name, and you'll get the robot's name! =)

Any old id string would work. If you have a bunch of robots, some sort of integer id would work well as well.

If Java had macros (maybe it has nowadays?) you could define makeRobot(foo, ...) to expand to Robot foo = new Robot("foo", ...)

4:21 PM

@Zgarb You could just put a static method in Robot to do that.

So I'll just write a getRobotName method. ok, thanks

@Geobits Even the variable declaration?

@Geobits I don't think so -- you'd run into "foo isn't a valid identifier"

@Eridan ...you are using the karel2 package.

Do I know you?

Oh right, I see what you're saying.

I read it as makeRobot("foo", ...)

4:22 PM

Yeah, that'd work ^^

^^

Twin Carrot: Best Carrot ^^

Doesn't that mean "two lines up"?

@VoteToClose Yeah I'm using karel

Of course, you'd need to name it Robot.robotFactoryBuilderFromANamedString("foo", ...) ;)

4:24 PM

@Roujo But you can never tell whether it's a reference or an emoticon.

What do you mean "Do I know you"?

:D I made an extension for karel2 that made it interactive once.

@Eridan I never expected to see that package again. :D I used it last year in my Java Programming course, and jokingly wondered if you were in my high school.

@Zgarb I never use ^^ for references, although I can see why someone would.

@VoteToClose inb4 he's your neighbor

You can always do ^.^ or ^-^ to avoid confusion.

Lol, I'm trying to write a golfing language that will be visualized with Karel. Putting beepers on spaces on the plane can easily substitute for stacks

4:25 PM

PhiNotPi

4:54 PM

@Geobits I'm not sure how much you've read about perplexity, but it is basically defined as 2^entropy.

I've read roughly that much.

Machine learning makes my brain hurt in several areas.

So you can get down to negative entropy without the perplexity going zero

> negative entropy

That sounds nice

Hmm. So single digits would be pretty damn good, really. Entropy < 4 can't be all that bad.

PhiNotPi

So, having a model with 30 perplexity (IDK what you've managed to get yours down to) is similar to a model that makes a uniformly random choice from 30 options.

4:56 PM

It's at 30.08 right now, fluctuating +- .25 per 50 steps. It's slowed down a lot, as you'd expect.

As the entropy drops, is your computer giving off more and more heat?

Huh. @Eridan's karel seems different from the one I used. Like somebody decompiled the source, edited bits, and repackaged everything.
