Ooo

user165474

alias doesn't seem to make it stick around; it is gone when I close the terminal.

Put it in your .bashrc

user165474

12:06 AM

...oh

user165474

thanks

user165474

Wait what is .bashrc

user165474

And where is it

~/.bashrc

user165474

Oh okay thanks.

12:08 AM

it's a shell script that's run every boot

I've used Linux for over a year now and I'm still a linux n00b :c

I've used linux for like a month, I'm still a noob, but I know how to customize it.

Riker

@totallyhuman *every time you open your terminal

... Right yeah >_>

I've been using Linux for a few months and I learnt what I needed and stopped there :P

Riker

lol

what distro?

12:15 AM

question: is there better way to create string in ASM than:

Oh and I forgot when bashrc is run because "I don't use Linux often, but when I do it's CLI"

    %val = alloca [2 x i8]

    %ptr1 = getelementptr [2 x i8], [2 x i8]* %val, i64 0, i64 0
    %ptr2 = getelementptr [2 x i8], [2 x i8]* %val, i64 0, i64 1

    store i8 <first char>, i8* %ptr1
    store i8 0, i8* %ptr2

Hmm

Really what I mean is I'm using Ubuntu on a Chromebook

It's kinda ridiculous :P

Trying to find the most pedantic solution to a diff + patch on binary files using Linux

Any suggestions?

12:18 AM

Fedora is easily my favourite distro across the ones I've tried.

user165474

How did I just get the mortarboard badge?

user165474

Unless it didn't count the 10 rep I lost earlier...

I don't believe it does.

user165474

Oh yay! :D

CMC: What is the slope of a line with an agle of pi/5 as a rise/run format

user165474

12:21 AM

tan(pi/5).

@HyperNeutrino Fixed cmc

user165474

well i'll be back in about 30 mins

user165474

to 1:30

@Christopher still tan(pi/5) = sqrt(5 - 2*sqrt(5))

@LegionMammal978 Or sin(pi/5)/cos(pi/5)

12:25 AM

But yeah, anyone know of any tool like the one I'm looking for?

@Christopher That's how I calculated it

0.587/0.809

;)

trying to graph a man shot out of a cannon 10 feet in the air at the angle pi/5 at 100fps

in a parametric

In that case, shouldn't it be a quadratic

Just use Kinematic Equations

@ATaco Not that smart

Nick Clifford

12:28 AM

does anyone else ever just suddenly lose interest in whatever you were doing?

@NickClifford Yes. This is boring

repl.it/Htul/7

It's slightly shorter now

@Christopher So like this?

@LegionMammal978 yes. equation?

12:43 AM

CMC: Draw a smiley face with equations :)

@HelkaHomba x=83

(-d cos(θ) + x - x_0)^2 + (-d sin(θ) + y - y_0)^2<=r^2 or (-d cos(θ) + x + x_0)^2 + (-d sin(θ) + y - y_0)^2<=r^2 or x^2 + y^2<=ρ^2 and (x - x_0)^2 + (y - y_0)^2>=R^2 and (x + x_0)^2 + (y - y_0)^2>=R^2 and (y - d_u)^2 + x^2>=u^2 or (y - d_l)^2 + x^2<=l^2

#Bingit

I don't see it ;)

@Phoenix I see it too much

Wolfram|Alpha FTW

I just typed "Smiley Face Curve"

12:49 AM

Reminds me of wolframalpha.com/input/?i=batman+curve

Anyone know how to get W|A to convert y=mx+b equations to parametrics?

repl.it/Htul/8

Wait

Is it possible to do random in brain fk?

user165474

Is someone trying this challenge in Jelly right now?

12:53 AM

@totallyhuman pseudorandomness is possible but would be very large and cumbersome

desmos.com/calculator/vwjdgh5txv

nice

Would anyone know how to include the current timestamp (in some format) as an argument to another command in Vim? I'm trying to do something like :w filename_<timestamp>.txt

DJ knows lots about things starting with v I believe

@Phoenix thats no curve

12:58 AM

@DJMcMayhem You know the answer to the question at ^^^?

1:15 AM

desmos.com/calculator/taxtdwbvs8

I can't figure out what i am doing wrong to graph it. Any ideas?

CMC: solve the problem in the image above

I think you need to graph the distance over time travelled not the arc of his flight.

wait

ETHproductions

@DJMcMayhem Aw, thanks :-) Looks like you'll get there yourself pretty soon!

I think you need to take into account where he lands on the ferris wheel or something

repl.it/Htul/8

doesn't desmos have an animation thing?

1:19 AM

Anyway to make this work?

@Christopher ok, so try try graphing it like this: using the arc already shown add a dot that goes across the line (should be somewhat simple), add a wheel, that rotates based on the slider that you use to make the point go across the line, and then add another slider that rotates the wheel a bit to make the delay at the start

@SimplyBeautifulArt what's it supposed to do

@ASCII-only I'm trying to do lots of inline conditions nested in each other

Updated TeamSpirit, Now usernames should disappear less.

@SimplyBeautifulArt wut

1:22 AM

@LegionMammal978 hmmm you could use exec to build up the filename, but I'm not sure how to get the timestamp from vimscript

@SimplyBeautifulArt How exactly is it not working right now

@LegionMammal978 Code supposed to make large number

@DJMcMayhem Could use external commands

@ASCII-only I can't figure out how to nest inline conditions and for loops in Ruby I think

Hmmm

@LegionMammal978 Which command would you use?

1:25 AM

@DJMcMayhem date +%s%3N probably to get the timestamp

Does :let time = !date +%s%3N work?

def f(a,b,c,d=a*a)b<0?c<0?d:f(d,d,c-1):(0..d).each{a=f(a,b-1,c)}&&a end

@DJMcMayhem looking for a oneliner, putting this all in an :au

@SimplyBeautifulArt ^^

Vim can execute arbitrary python, right?

1:29 AM

@LegionMammal978 You can put multiline commands in an autocommand

@ASCII-only Thanks!

@DJMcMayhem How so? Could you just give me teh codez for how I'd write it? Not too good with vim

@Phoenix Yeah

@LegionMammal978 I'm not sure how I'd write it either, but for writing I'd use exec to build up the filename, and for multiline autocommands, use the backslash to escape Newlines (I think)

@DJMcMayhem lol, why is it so hard to keep a continuous log of every revision to a document :P

Just trying to create a copy every keystroke (here with :au TextChangedI)

Good Lord

1:34 AM

It's only a kb or so on an SSD

@LegionMammal978 I take it back, here's what I'd do (rough outline)

function! WriteTimestamp()
  "Do stuff
endfunction

au TextChangedI * call WriteTimestamp()

@DJMcMayhem So save it into a file and run that how?

import datetime
print datetime.datetime.now()

That function would be in your .vimrc

And I guess I can replace * with my filename

1:37 AM

I think?

So how would I input this variable from let time into w?

Just a sec

@LegionMammal978 What is the base filename (without the timestamp)?

@DJMcMayhem Just assume it's filename

:exec "w filename_".time

So . is string concatenation?

1:42 AM

Yep

Thanks for the help, that should be it!

Wait, should I just create it as ~/.vimrc?

function! WriteTimestamp()
  let l:time = strftime("%T")
  exec "write filename_".l:time
endfunction


au TextChangedI * call WriteTimestamp()

@LegionMammal978 Yeah

Except you'd have to change the * to whatever filename you want this autocommand to apply to

Thanks! I guess I's use "%+%s%3N" here as well

@TuxCopter It's been fixed, You'll just need to update.

@DJMcMayhem Weird, modified the code to use system, now it's bork

user165474

@NewMainPosts For this challenge, my potential answer is slightly off on the large test cases due to floating point issues; is that generally acceptable?

2:56 AM

@DJMcMayhem golfing long overdue :P

Lol, I don't think I can

@DJMcMayhem explanation long overdue

@ConorO'Brien do you happen to be familiar with haskell

@Downgoat not especially. I never did like it much. why?

I was wondering if you know how to functional operator in haskell

3:08 AM

a la cheddar?

you forgot the grave accent :P

but (+) doesn't work unforunetly

wait what

Are you trying to code in Haskell or implement better functional programming in Cheddar?

code in haskell

I know I wasted 2 years on cheddar but it is honestly too slow and buggy to ever be remotely useful so I'm probably not going to work on it anymore

VSL is going to be like Cheddar++

@Downgoat yes it does actually

remember functions are called like f x y, so it's (+) 3 4

hm :/

I am trying to curry

(+) 1 gives error

3:12 AM

like this?

:| GHCI not letting me do it

try copying the exact code and see if it works?

*** Exception: Prelude.read: no parse

ok this is new error

try it with runhaskell?

@Downgoat VSL?

ide.c9.io/somebody1234/node-vsl

3:14 AM

@Phoenix :O you don't know about VSL? D:

VSL

you are very welcome to help make

here is spec: hackmd.io/KwZgnALAJsCmUFoJlgNiQBlAgRsAjAIYIAcJhJUGATMNScIUA===

originally a lot of people were in project, but then when it came time to actually code VSL everyone went away

Thanks

VSL is coded in like every language so if you want to help you probably can

Does "every language" allow C#?

C9 requires a credit card ;-;

Yeah, can't you use Gitlab instead?

Also, is the longer type a BigInt or an int128

3:19 AM

it is free, but it requires a confirmation of age/identity, thus a debit/credit card.

But I don't have a credit card ;-;

@Phoenix GitLab isn't an IDE

You can use a parent's as well, if they trust it.

@Downgoat yes, also they stopped providing feedback

@ASCII-only I can't tell what C9 is, due to the aforementioned credit card requirement.

3:21 AM

@ATaco you can remove credit card after entering

@Phoenix it's online code editor

I'm not going to; I'm a trusting lad.

where we can code together realtime

I've signed up with my Debit Card.

It has a github though

so you can still contribute

I have noticed that there is problem and that is I have to make libvsl, i.e. libc for VSL

Even if C9 was easily accessible, I would use a Jetbrains IDE instead.

3:22 AM

does jetbrains support floobits

There's a plugin for floobits that I used back when coup was a thing that we thought might have a future.

can C# compile to windows dlls?

@TuxCopter can you come back to VSL :3 we have to write C code and you do C right

@Downgoat It can compile to .NET DLL

can you specify alignment in C?

@Downgoat alignment?

3:26 AM

bit alignment

What's VSL's typing?

Strict.

It seems.

static and implicit

Javascript's ducktyping is evil.

yeah

3:28 AM

Can I put in a vote for C#? int foo = 5 if you want, var foo = 5 if you want.

@Phoenix wait @ASCII-only is also C# person, you should talk to him

If we're using C# we may as well use Java for compatibility.

@ATaco hahahahahaha

I'm looking at the function syntax rn and I'm salty that JavaScript is winning over Java.

It's almost the same, but in a statically typed language it makes more sense to include the return type

@Phoenix On the spec? You can do it yourself, just sign in with GitHub and edit it (if you mess up the votes I can always roll it back)

3:30 AM

@Phoenix no JS?

@Phoenix We will, just after the method declaration fn foo() -> Int { 1 }

wait what

oh no

sorry functions look like:

VSL..?

public func greet(person: Person, with message: String?) -> Void {
    ...
}

@ATaco is question mark about what abreviation stands for

3:33 AM

Know, I was questioning the syntax.

question: can someone please explain significance of number 94.1337

What is with?

you would call withL

Example?

greet(person: bob, with: "hello, I am downgoat")

Arjun

3:34 AM

Hey!

however inside the function, you would access the with argument as message

Arjun

question: Are Mario games turing-complete?

@Downgoat is message: valid as well

@Downgoat Can you pass me write access..?

@ASCII-only no

3:35 AM

@ATaco yeah its bs

@Arjun See MarioLANG

@Downgoat :(

@ATaco ask @ASCII-only, but pls don't mess up, have not commited code

@DestructibleLemon wait I have my own c9 instance

@Downgoat Can the part where you explicitly give parameter name be optional?

@Arjun Yes, Very much so.

So if it's not overloaded you can still just do foo(bar)

3:36 AM

@Phoenix yeah, except the function should specify that

@Arjun hmmm, through some glitches you can get the game to run machine code, but that's the consoles lang

so not really

it's not like python named parameter which is weird

I've been powerleveling my NodeJS knowledge over the past couple of months.

a-ta.co is almost entirely written in NodeJS.

however coolest part is you can have same function with different named parameter. e.g.:

func modify(goat: Animal) and modify(dog: Animal) can both be in function

@ATaco what is stack?

public func a(with m: String?) -> Void{}
public func b(with m2: String?) -> Void{}

3:38 AM

Idea: Create C-like preprocessor for VSL?

@Downgoat Stack..?

@ATaco like, Express + React?

Oh, nope, mostly stack-free.

@ATaco that won't work because m/m2 is private to the function

@ATaco so like how are you serving stuffs

I also want to point out that I disapprove of Void being upercase.

3:40 AM

@ATaco that's debatable; the code is actually being altered, so that just shows that the console processor is tc (disregarding memory)

I wrote a thing myself which servers the contents of /www/ similar to apache.

@Phoenix oh you don't even have to specify that part

I just added that to show return type syntax

@DestructibleLemon The game was used to write that code, it's at the very least a TC compiler.

Ok

@ATaco imagine this: I have a program that writes to the boot sector of my computer: I can make the boot sector do anything. that doesn't make the writer TC

3:42 AM

I'd like to imagine it's still TC, it's more fun that way.

nooooooooo
not the can we really have TC debate
It's boring

ok. what should the data model for my disk lang gyre be?

The amount of times I've rehashed debating TC here... It makes me want to do it again!
