Does anyone know who wrote this? The user got destroyed apparently; I forget who wrote this

ASCII-only

@HyperNeutrino SIGSEGV maybe?

Dennis

.oO(I do.)

Nitpick: the user got deleted. When a user is destroyed, their posts are deleted as well.

ASCII-only

@Dennis D: Why are speaking your thoughts out loud

This is like the first sign of villainy or something

Before you know it you'll be monologuing out loud

Dennis

@ASCII-only Odd, I thought the first sign was writing your name in blue.

user165474

@Dennis Sorry, I meant deleted :P I forgot which was which.

user165474

3:13 AM

Wait... @Dennis If someone has a higher user ID than me, they are a newer user than me, right?

Leaky Nun

@HyperNeutrino yes

Dennis

Yes.

user165474

It couldn't have been the old SIGSEGV then because SIGSEGV (64499) is an older user than user69783

user165474

actually

user165474

user##### means that the id is ##### right

Leaky Nun

3:14 AM

@HyperNeutrino somehow you're older than me.

How come I don't recall you.

user165474

I lurked around a LOT

user165474

I'm an older user than Mego as well

Dennis

@LeakyNun If I had to guess, for the same reason someone might not remember you, but would remember Kenny Lau.

user165474

I became active around the same time you became inactive.

user165474

OH RIGHT

user165474

3:16 AM

I used to be called Alex L.

Leaky Nun

@Dennis I changed my name to Leaky Nun long before my hiatus

Dennis

Yes, I know.

user165474

how did this get an upvote

Leaky Nun

@HyperNeutrino you never pinged me before I left

user165474

Hm. Ok.

user165474

3:18 AM

Wait my first ping to you was less than 2 months ago...

Dennis

@LeakyNun False.

user165474

@LeakyNun Was your name changed because of memes?

user165474

@Dennis Those were during the short period when SE got confused by Leaky Nun having different names on different sites IIRC

Dennis

No, wait.

Right.

See? Even SE is confused by the constant name changes. >_>

user165474

but you're a mod and mod=god

Dennis

3:21 AM

More like mod = glorified janitor.

user165474

lol that's one way to think about it

user165474

or as SE puts it, "human exception handler"

Leaky Nun

@HyperNeutrino ya

user165474

Oh right there's a star

Leaky Nun

I changed it long after the meme was inactive though

user165474

3:23 AM

Ah ok, I see.

What are a and n?

Leaky Nun

a(0) = 1, a(1) = 6, etc.

MD XF

Oh

Leaky Nun

a(n)/6**2n is the probability of getting the most probable sum on a dice roll of 2n dice

Q: How many dice can you roll without rolling the most probable number

Problem Starting from n=2 dice: Roll n dice, with each number 1 to 6 equally likely on each die. Check if their sum equals the most probable sum for n dice, that is 3.5*n. If they're equal, terminate. Otherwise, print n, and repeat from the start with n+2 dice Your code doesn't have to...

of course there is a shorter formula

The probability of getting the most probable number with 2n dice is A063419(n)/(6^(2n)). — Leaky Nun 13 secs ago

That is a huge formula

MD XF

ASCII-only

@MDXF But the resulting executable will be insanely slow

Leaky Nun

ASCII-only

... Hyper is actually better than Cmder though

Same reason why I use Vivaldi

MD XF

But cmder is 100% native Windows

so it's guaranteed to be faster

ASCII-only

@MDXF It's 100% native MinGW

ATaco

4:37 AM

Why not just Putty into your own computer?

MD XF

@ASCII-only Ehh I don't think cmder is as based off of MinGW as you think

ASCII-only

@MDXF Well yeah but I only installed MinGW recently, I usially don't need it

I have WSL and Cygwin for that

MD XF

Yeah... and even MinGW is native Windows, they take the source code and compile it natively

Oh Cygwin is the worst

I mean it's good for testing Linux applications when you don't want to reboot but they have the most terrible methods of getting POSIX on Windows

ASCII-only

@MDXF How, its support for commands is like 100x better than MinGW

MD XF

True, it has more Linux utils, but it's slow and crappy

Destructible Lemon

is it bad practice to use exceptions to pass information when under specific circumstances

(as in, when a bot does the wrong thing, I will raise an exception, and then in the game layer catch the exception)

ASCII-only

5:48 AM

@DestructibleLemon In Python, no :P

Destructible Lemon

@ASCII-only explain

wait I think I figured out a better way to do it than just passing info

is it bad to throw and use try and catch blocks?

ASCII-only

@DestructibleLemon No because that's part of the recommended Python style IIRC

Destructible Lemon

ok then

Should I make a new type of exception then?

ASCII-only

Yes (but realistically you should try not to use exceptions, they're probably slower than conditionals)

Destructible Lemon

practically if the error code ever gets used it will actually speed up the match because it kills the bot

anyway how to define exceptions?

I guess I'll just look that up

the symbol is really small

@Fatalize Just like monadic , flattens the array into a simple list, ⍪ "flattens it into a simple matrix. If it is a list, it becomes a column matrix.

Adám

@Mayube That's strange. Mine is still half a pixel lower. Probably a grand sum of video card+screen properties+browser+cleartype settings.

Mayube

@ASCII-only Well that version number is too similar to be something completely different, so you're probably running Chromium, Brave or another chromium fork

ASCII-only

@Mayube Yeah, Vivaldi

Mayube

I'm weird with browsers

I used to use Firefox Dev Edition, but it started being really unstable, and using way too much CPU, so I switched back to chrome, despite the ram issues. Then I switched to Brave, but Brave's builtin adblocker makes no attempt to hide itself, so some sites I use that lock themselves up when they detect an adblocker I have to use chrome for, because uBlock origin is better

and at work I use chrome because our platform only supports chrome

ASCII-only

@Mayube Why Dev edition

Adám

8:17 AM

I keep trying other fonts for APL, but always come back to APL385 Unicode:

Mayube

@ASCII-only because I can't stand the Aurora skin, and I like Dev Editions' skin

plus I'm a web dev, so it makes sense

Also @Adám does APL really run right-to-left?

Adám

@Mayube Kind of. It runs right-to-left in the same sense that - in mathematics runs right-to-left, i.e. for -3 you first look at the 3, and then negate it.

Mayube

huh, interesting

Adám

@Mayube You may counter that the - is part of the number, but then consider -a

Mayube

yeah I would argue that - is more a "modifier" of sorts to the number

and you can't modify a number if you don't know what number to modify

ASCII-only

8:26 AM

@Mayube It's a prefix operator

Adám

@Mayube Basically, APL is a generalized mathematics, with as few parsing rules as possible. So just like - is used in math for both negation (when prefix) and subtraction (when infix), so has (almost) all APL primitives two meanings; one as prefix and one as infix. And just as all the prefix functions take whatever is on their right as their right argument, so do all primitive functions in APL.

@ASCII-only In APL, what mathematicians (and most programmers) call operators are instead called functions, as they served the same role as named things, like f(x).

Mayube

@Adám So -3 isn't the literal -3, it's the function - being passed the literal 3?

Adám

@Mayube Correct. The number "negative three" in APL (and TI-BASIC) is ¯3.

@Mayube So APL is very easy to parse (let's ignore APL "operators" – higher order functions – for now): Every function's right argument is whatever is from its right-hand side to the end of the statement. E.g. in 2×3+4-5 the right argument of + is 4-5, and the right argument of × is 3+4-5, so the entire statement is parsed as 2×(3+(4-5)).
