The Nineteenth Byte

Stata and SAS answers bug me a bit (though I've posted the latter at least once) because there are no free or easily accessible interpreters. Well I guess SAS has University Edition now, but it didn't when I posted my first SAS answer here.

@quartata lol rekt

SAS University Edition requires massive setup though. It has to run in a VM so it requires VMWare or VirtualBox.

quartata

Mathematica answers kinda make me mad too even though they have a demo simply because in order to get the demo you have to put in your address your real name and whole bunch of other stuff

Alex A.

Yeah :/

I will admit part of the reason why I'm confident my answer will stay safe is that it does require deep knowledge of how PBASIC works.

Mini challenge: Print from 1 to input n, arranging the numbers in vertical columns. e.g. n = 15:

         111111
123456789012345

quartata

I don't think just looking it up would be enough. SO it's not like I'm just using an obscure language. It is a tough problem.

El'endia Starman

@Calvin'sHobbies Does this have to work for 3 digits too?

quartata

@Calvin'sHobbies Ooh

Calvin's Hobbies

@El'endiaStarman Yes

El'endia Starman

Ugh why do I have to put in my address and zip code for mathematica

DankMemes

I feel like there's going to be some sort of magic regex for that challenge

Calvin's Hobbies

12:17 AM

@Sp3000 It's so easy visually :P

Sp3000

The best way i can think of currently involves 1) flood fill and 2) BFS, neither of which sound fun :P

GamrCorps

@Calvin'sHobbies Do standard loopholes apply?

Calvin's Hobbies

@GamrCorps Yes (they always do unless stated otherwise)

GamrCorps

darn....

ok time to seriously golf java code...

quartata

@GamrCorps If I ever finish Downdraft you'll be able to golf Java faster than conventional means

Calvin's Hobbies

12:18 AM

@Sp3000 I was thinking move one of the shapes in each of the 4 directions. If one direction causes no overlaps then it's truthy.

Alex A.

@CᴏɴᴏʀO'Bʀɪᴇɴ I don't know if you have Mathematica to test, but FYI the Mathematica code from the other answer to your challenge doesn't work for me.

DankMemes

@Calvin'sHobbies ah clever

I'm thinking test all 4 directions for a BA+B or AB+A but does that always work?

Calvin's Hobbies

I guess you still need to know the sections, sections, hence flood fill or something.

GamrCorps

@quartata I tried to make a challenge to remove whitespace from code. Had to end up closing it. Looking forward to Downdraft though.

Calvin's Hobbies

@DankMemes Those aren't simply-connected, therefore not valid input

Sp3000

12:20 AM

Is just checking 4 directions enough?

DankMemes

no no, for example

BBBB
BAAB
BABB

B

DankMemes

haha late to the party

Calvin's Hobbies

@DankMemes I mean moving the entire A chunk will cause overlaps

@Sp3000 I think so. There's no empty space so the shapes have to slide apart in one motion in a cardinal direction (if they can)

Questions like this one make me realise how much Slip is missing. I have an anchor for edges, but no way of going "I want to start from one edge and match all the way to the opposite edge" :/

Alex A.

@Sparr "Golfing," at least on this site, is used as a verb to describe the process of reducing the number of bytes in a program. :)

So I assume you mean "golfing" the sport.

Nathan Merrill

2:03 AM

who are you to define what a sport is?

Alex A.

"Golfing" the sport in which one smacks a little white ball with a stick and has to go find it in the grass because it's nowhere near the little hole in the ground where it's supposed to be.

@NathanMerrill Better? ^

Nathan Merrill

They make a mouse for desktop use that's a trackpad. (It's kind of weird IMO.)

Do you just use an external mouse then?

when I'm at home I do (always forget to take it with me)

no I actually have the El Capitan beta

DankMemes

why does apple love just blatantly ignoring standards?

Alex A.

@DankMemes You can probably configure it to do that, but once you're used to using Cmd, things are actually a lot nicer. You can copy/paste in places where the control key does other things.

thats as far as they will go

DankMemes

like "there's a USB mass storage protocol? Screw you all, iphones need itunes to be able to copy files"

"right click? disabled by default"

Alex A.

Why would you want an iPhone without iTunes? It's a convenient means of managing what's on the device.

DankMemes

"bluetooth file transfer? lol nope, we have airdrop that literally only works with apple devices"

Alex A.

And I don't think right click is disabled by default. If I plug in a mouse I can right click no problem.

DankMemes

all the apple mice I've used for desktop imacs have no right click

my default file manager is an even more convenient for managing files on my android phone

no need to get more bloatware

Alex A.

2:31 AM

@DankMemes If it's all white and is shaped like a mouse with no buttons, just click the right side of it. It's a right click.

DankMemes

I've tried but it doesn't work

Alex A.

Then try two finger click.

I can never remember because I rarely use a mouse.

GamrCorps

CTRL-click will work too

DankMemes

yes, that's what I use ^

I'm just saying, why make it so complicated?

Alex A.

Ctrl click? Cmd click, you mean?

DankMemes

2:32 AM

no

GamrCorps

no CTRL-click

DankMemes

ctrl click

just make mice with a hardware right click

cmon

not that hard

Alex A.

You can use a non-Apple mouse and right click will work as expected.

DankMemes

no 2 finger click or ctrl-click shenanigans

GamrCorps

@AlexA. thats what I do

Alex A.

2:33 AM

You don't have to use their mouse. Just any regular bluetooth or USB mouse will work.

DankMemes

computers at my school tend not to let you use your own mouse :P

Alex A.

Oh you're right re ctrl+click. I was thinking cmd+click because it opens things in a new tab in Safari, which I do all the time.

DankMemes

also I'm pretty sure my school could have gotten windows PCs instead of imacs and saved like 50% of the cost

Alex A.

@DankMemes You have iMacs at your school and they all have the Apple mice? That sounds like a well funded school.

the school I used to go to bought ipads for every student

I kind of preferred that one

Alex A.

@DankMemes I'd probably be better off teaching math than CS unless it's programming. I don't really know any actual CS.

DankMemes

and I guess ipads were the best choice even if expensive because if they were android tabs, everyone would have them rooted in like 2 days

No, it's actually redefining the + function in your workspace. Inside the function it's using the base primitive function.
