A: Sandbox for Proposed Challenges

Remove duplicated & switched case code-golf string Goal The goal is, having taken a string as input, remove the following duplicate of each latin letter with a following "triggered" case (i.e. uppercase becames lowercase and vice-versa). Example inputs & outputs: Output: Input: bBaA...

aloisdg

I submitted a challenge in the sandbox which is a reverse of a challenge made by @nicael. It is allowed?

Downgoat

@aloisdg sure, lots of challenges are made that way, just make sure the original and reverse's solutions wouldn't be too similar

In windows, can I make everything else except the cursor 200% bigger?

aloisdg

@Downgoat I implemented both and my algorithms are very differents :)

quartata

@Downgoat Yes use magnify

Although I'm not sure why you'd want to

Do goats need glasses?

Downgoat

@quartata I'm on HiDPI so my resolution is 2880x1400 but it should appear as 1440x900 so in order to do that I've set the resolution to 2880x1400 but am magnifying everything by 200%

I've magnified it in display settings

question: what's the difference between visual studio community and regular visual studio?

(besides the fact that VS community is free)

aloisdg

9:31 PM

@Downgoat not so much

SEJPM

@Downgoat enterprise has some advanced bonus features

pro not so much

license is different of course

Downgoat

ok. So i can still make MSI installers with VS community?

SEJPM

MS comparison

@Downgoat yes, this is an add-on

and you can install add-ons into VS CE

Downgoat

ah ok

aloisdg

@Downgoat visualstudio.com/en-us/products/…

@SEJPM faster than me :)

SEJPM

9:35 PM

@aloisdg :)

Downgoat

> Refactoring

TIL you can buy refactoring

quartata

@Downgoat It's things like rename a class, format/indent code, etc

Downgoat

ok, seems useful.

SEJPM

this is actually quite difficult with C++ so it's a feature

VS didn't have C++ refactoring up until VS2013 where it was an add-on IIRC that came late in the life cycle

Downgoat

what do you use for coding

quartata

9:38 PM

@Downgoat Netbeans for Java, vim for everything else

SEJPM

VS (+ Notepad++ when doing Prolog sometimes)

El'endia Starman

@Downgoat I can't believe you forgot Notepad++.

Also, I usually use IDLE for Python coding.

Downgoat

but why would you use notepad++ when you can use ((n)v)im

aloisdg

visual studio code is more atom than visual studio

SEJPM

@aloisdg still more VS than Notepad++ and other stuff (+ better multi-lang support)

9:42 PM

How can I scale a div (not resize)? Like browser zooming, but for a single div.

Downgoat

@mınxomaτ transform: scale(<scale size>) IIRC

where <scale size> is like 0.5 for 50% 2 for 200%

cheddar> [1,2,3].each((item) -> print item)

i made a thing :D :D :D :D :D :D \o/ \o/ \o/ \o/

Dr Green Eggs and Iron Man

@Downgoat Why can't I select two or more? I use vim, visual studio, and like 3 others.

Downgoat

well what do you use most or for just general coding

Dr Green Eggs and Iron Man

It completely depends on the project.

Downgoat

Hello @HelkaHomba!

Dr Green Eggs and Iron Man

9:51 PM

Oh, general? then vim.

Downgoat

:D

i thought you use nvim?

Dr Green Eggs and Iron Man

Which probably doesn't come as a shock.

Windows, remember?

Neovim only sorta runs on windows.

Downgoat

question: which is better? "Foo".lower or "Foo".lower()

the former would be faster

Dr Green Eggs and Iron Man

Does it modify the string itself?

Downgoat

@DrGreenEggsandIronMan D:

Dr Green Eggs and Iron Man

9:53 PM

Or return a modified copy?

Downgoat

@DrGreenEggsandIronMan no, it returns a new string

Dr Green Eggs and Iron Man

Then either one.

Downgoat

._.

ill go with former then because speed

Real programmers set the universal constants at the start such that the universe evolves to contain the disk with the data they want.

@Doorknob wait, since you're a doorknob, how do your hands work?

o_o

\o/

to check if an array has an item, should it be has, includes, contains, or something else?

aloisdg

Contains is used by .net

Downgoat

9:59 PM

JavaScript uses both includes and contains

aloisdg

javascript...

kidding

why the use both?

they

Downgoat

idk

Helka Homba

@Downgoat He

llo

orlp

s,*P;main(q,c){char*p=P=1[P=c],*o=p;for(;c=*p++;c^=32,s+=c^9?c==8:-1,*o=s|c?c^32:10,o+=s|c||q,q=c);*o=0;puts(P);}

ArtOfCode

@Downgoat contains makes most grammatical sense

aloisdg

10:14 PM

someone know how to use regex to keep a letter only if the following letter is the same with a different case?

El'endia Starman

@Downgoat A.contains(x), x in A.

quartata

Hey, can anyone who knows MATLAB tell me how to plot a piecewise polynomial?

I could use ppval maybe but it seems like there should be a built-in

dorukayhan

@aloisdg you can use

aA|Aa|bB|Bb|cC|Cc|dD|Dd|eE|Ee|fF|Ff|gG|Gg|hH|Hh|iI|Ii|jJ|Jj|kK|Kk|lL|Ll|mM|Mm|n‌N|Nn|oO|Oo|pP|Pp|qQ|Qq|rR|Rr|sS|Ss|tT|Tt|uU|Uu|vV|Vv|wW|Ww|xX|Xx|yY|Yy|zZ|Zz

to find such letter pairs

quartata

Ah oops nevermind

Forgot how to use plot( for a second :P

dorukayhan

is it normal to run out of flags just by taking care of review queues on stack overflow?

El'endia Starman

10:20 PM

Stack Overflow? Doesn't surprise me. Anywhere else? Probably not normal. :P

flawr

@quartata unfortnately there is no builtin

quartata

Yeah I'll just use plot(0:foo, ppval(p, 0:foo))

Little annoying but eh

aloisdg

@dorukayhan not really what I had in mind x)

flawr

@quartata I didn't know ppval, what version are you using?

quartata

Octave 4

flawr

10:31 PM

oh

It's official now!

A: What programming languages have been created by PPCG users?

V V, short for vim and pronounced "vee" is a golfing language designed by me. V operates by performing transformations on a giant 2D array of strings. Although all of the builtins are fairly simple and trivial operations, such as dw, (d)elete a (w)ord, or fn, (f)ind the next occurrence of the ch...

aloisdg

10:46 PM

nice :)

Dr Green Eggs and Iron Man

@aloisdg I can't test this right now, but couldn't your do something like (\u)\U\1|(\l)\L\2

Wait, nvmd that's backwards.
