@ASCII-only the challenge was inspired by this :P

@flawr Then how do you determine order of execution?

Ah right, I didn't notice that the spaces were still providing that!

Does anyone have time to review a KotH controller I wrote for a challenge?

flawr

What language?

wizzwizz4

flawr

Then no, sorry =/

wizzwizz4

Ok.

Could you review the actual challenge proposal?

Except if you think that understanding Java is enough

@flawr Probably.

Q: Texplode KotH controller

I am creating a KotH (King of the Hill) challenge for Programming Puzzles and Code Golf. Other site users will write programs that play Texplode (a version of this game on a square grid). The program works, but I don't think it's anywhere near perfect; I don't often publish C programs so I rarely...

TheLethalCoder

Can you read C#, Java and C++? They'd help you with understanding it

@wizzwizz4 If you've posted it to code review I think you're probably best waiting for one of them to answer. They'll probably give you a better review than someone who doesn't know the language could.

wizzwizz4

@TheLethalCoder It doesn't necessarily need to be Code Review standard, but it does need to be understandable by the average (skilled) PPCG user.

flawr

@wizzwizz4 Is there something I should look out for in particular?

wizzwizz4

@flawr That it's readable ~~and works.~~

TheLethalCoder

@wizzwizz4 Do we need to be able to read the controller for the KotH?

wizzwizz4

3:17 PM

@TheLethalCoder ... Not really.

flawr

First of all the link to the game is dead

wizzwizz4

It would probably have been a better idea to ask you to review the sandboxed challenge instead.

@flawr I know. :-(

I haven't found an implementation as good anywhere else yet.

trichoplax

I almost posted my latest KotH controller to code review too, but settled for just asking PPCG to test it

flawr

@wizzwizz4 ok I don't think I can help, as I don't know the game, and don't understand a few of the functions you use.

Oh look, there is even a comment in your code :D

TheLethalCoder

Is the reverse Fibonacci challenge just a dupe of the normal one?

wizzwizz4

3:21 PM

@flawr atoi is string to int.

@TheLethalCoder Do you mean the one that alternates + and -?

TheLethalCoder

@wizzwizz4 No the latest one Literally called Reverse Fibonnaci

wizzwizz4

Bleh. Now I remember why I put it on Code Review.

flawr

@wizzwizz4 I read that in french=P

@wizzwizz4 what is memset?

wizzwizz4

@flawr Erm...

Oh. It sets the value of a block of memory to the same number.

Found the prototype: void *memset( void *dest, int ch, size_t count );

flawr

ah, thanks!

My only experience with languages that let you access the hardware was C++, but I think I forgot all of it.

We've stopped updating at work because of it.

mınxomaτ

I can't kill any task without Task Manager crashing. I can't open my start menu.

wizzwizz4

I'm currently in a routine of patching and modifying the system frequently enough to counter the updates.

@mınxomaτ Open cmd with the "Administrator" box ticked from Task Manager.

For what now?

wizzwizz4

Then use the commands to task manage from the command line.

@TheLethalCoder How? I didn't know that was possible any more.

@StepHen I'm just letting you know the accepted standard meaning for use of carets so that confusion doesn't occur in less simple circumstances.

I also think your name looks out of place in the transcript and in the chatroom so I'd still recommend changing the entire name back to normal. Besides, you'll attract imitators and neither Dennis nor I are looking forward to that.

@Christopher And I appreciate it.

Downgoat

creating new one seems like bad idea because then it will set false precedent that all old challenges can be rewritten

Christopher

@Christopher About me saying I keep my name normal for him

trichoplax

4:51 PM

@StepHen Well, I've written 2 or 3 programs. Not an expert. But I'd guess because any string that doesn't cast to another number casts to zero

John Dvorak

@StepHen String.prototype.valueOf() === ""

Step Hen

@JohnDvorak oh, mkay

John Dvorak

It is the prototypical string object

Downgoat

@StepHen hahaha, this is hard to explain. Due to the way prototypical inheritance works String.prototype is kinda sorta an empty string (length = 0) while methods are unenumerable so you don't get an object so it's .toString() is actually "".toString() meaning when you do that it's actually "" == 0 which both are falsey

Step Hen

There are so many weird things in JS that are truthy but == false

John Dvorak

4:52 PM

The trick is to avoid ==. Then javascript becomes a fine language.

Step Hen

@JohnDvorak I know but this is for the CnR thing :P

John Dvorak

oh. Have fun then.

Step Hen

and the other really, really weird thing: NaN ** 0 === 1

as in, "Stephen" ** 0 === 1

trichoplax

JS thinks 0**0 === 1

Downgoat

@StepHen I mean 99.99% of thing to the power of 0 is 1 so not that weird

Step Hen

4:55 PM

@trichoplax It does in IEEE I think

trichoplax

So it makes sense since any non-numeric string casts to zero

Step Hen

@trichoplax they cast to NaN, I think

Downgoat

@StepHen only in non-+ arithmetic expressions.

they are replaced with the unused single char ones

wizzwizz4

@NoahCristino It may well evolve from that.

Like pyth.

now I can take all the jelly answers

and remove bytes

then conquer the world hahahaha

wizzwizz4

@NoahCristino Careful that you cite the originals.

Noah Cristino

wizzwizz4

5:29 PM

And that seems rather boring.

Noah Cristino

it took a long time

and I kinda ran out of characters

So it's not finished

wizzwizz4

@NoahCristino What do you mean?

No, I mean cite the original answers.

Noah Cristino

ik

I mean there were only 50 unused 1 byte chars

and there are more 2 byte chars then 50

wizzwizz4

@NoahCristino Work out which are the most common by programmatically analysing all Jelly answers.

Noah Cristino

or I can just add in more characters

wizzwizz4

5:32 PM

@NoahCristino Then the representation of each character will be more than a byte.

Noah Cristino

why?

what if I take something like

wizzwizz4

Because there are only 256 possible characters representable by a byte.

2^8 = 256

00000000 to 11111111

Noah Cristino

⥊

that's one byte

wizzwizz4

@NoahCristino No. 3 in UTF-8.

It's one character.

Noah Cristino

wow

so I ran out?

wizzwizz4

5:35 PM

@NoahCristino Yes.

Noah Cristino

that sucks

wizzwizz4

@NoahCristino It's the reason that we need hard drives.

MetaEd

It's the reason you need quadragesimal notation.

wizzwizz4

If we could fit an arbitrary number of symbols into a byte, we could store everything in a single byte.

Noah Cristino

MetaEd

Using quadragesimal notation, simple texts can be stored as 3 characters per 2 bytes.

Poke

@Christopher I wasn't planning on doing anything with it. I was just pointing out that not many people openly discuss that sort of thing. I suppose theoretically that type of information could be used when social engineering. /me shrugs

trichoplax

@MetaEd Do you mean "quadradecimal" (base 14) rather than "quadragesimal" (lasting 40 days)?

(I learned 2 new words today...)

John Dvorak

5:43 PM

I think he meant base-40

that doesn't fit either, though

40^2 < 26^3

trichoplax

Maybe some letters don't get included

John Dvorak

cbrt 40^2 = 11.7

Noah Cristino

I'm too lazy to under stand what you guys are saying

John Dvorak

sqrt 27^3 = 140.3

trichoplax

If "bytes" still means 8 bits, then 2 bytes is 16 bits so 3 characters would mean 5 bits each (32 possibilities) so you could get almost all the letters and numbers if you use I for 1 and O for 0 and drop two others

John Dvorak

5:50 PM

QX

l -> I

trichoplax

You could even use the left over bit to indicate whether the 3 characters are letters or numbers, you just wouldn't be able to have both 1 and I in a 3 character block

@Christopher No, I like everyone.
