Gabriel Benamy

Instead of ideone, you can use tio.run/nexus/perl

here's an observation as a long-time-lurker

DJMcMayhem

18:08

TIL I am the seventh user ranked by bronze and silver badges. XD

wyldstallyns

there's a lot more 'golf' than 'programming challenge'

Eᴀsᴛᴇʀʟʏ Iʀᴋ

@DJMcMayhem lol nice

@wyldstallyns yeah, that's to be expected

ETHproductions

@DJMcMayhem Where can you find that info?

DJMcMayhem

Yeah, now I just need to work on my golds, haha

@ETHproductions I just went to the users page, sorted by rep and counted

ETHproductions

Ah

TimmyD

18:10

@wyldstallyns That's pretty logical. Code golf is a) easier to code, b) easier to write challenges for, and c) easier to objectively score and compare than other forms of challenges on this site.

DJMcMayhem

I think you're 19th in bronze

zyabin101

I'm currently failing to install Ubuntu on a VMware Player virtual machine.

DJMcMayhem

I think I'm 23rd in bronze, there's Mego and Zgarb on the second page

wyldstallyns

would it be fun to write competing algorithms for Lemonade Stand and Oregon Trail?

zyabin101

It would. :3

TimmyD

@DJMcMayhem I don't think that's necessarily accurate.

TuxCopter

@zyabin101 Why on your conlang repo you listed l, m, n and r as 'sonorants'?

This category of sounds don't exist

They are voiced

DJMcMayhem

@TimmyD Well I can only see 6 users with more bronze/silver than me. How would you count it?

zyabin101

18:14

@TuxCopter In Lojban, lmnr are sonorant.

For simplicity, I put these in a separate category.

Kritixi Lithos

@ETHproductions BTW, solved your sandbox question in 12 bytes :)

Eᴀsᴛᴇʀʟʏ Iʀᴋ

> a sound produced with the vocal cords so positioned that spontaneous voicing is possible; a vowel, a glide, or a liquid or nasal consonant.

that's a thing

feersum

In Bash how can I get the PID of a process when I'm starting it?

zyabin101

@KritixiLithos Now publish this when the question comes. :)

(Yes, they are voiced.)

1) When I choose the Ubuntu ISO image in the Virtual Appliance Wizard, it triggers Easy Install (TM).

ETHproductions

@KritixiLithos Which one? I have like seven :P

Though I assume you're talking about the one I just posted

TimmyD

18:15

@DJMcMayhem You'd need to do it via API to get an accurate count.

zyabin101

I just need to enter the identity of the initial {us,sudo}er and it works.

Kritixi Lithos

@ETHproductions ASCII-bet

zyabin101

But that's where what supposed to be fun stopped being fun.

TuxCopter

@feersum $$?

feersum

Example?

ais523

18:17

that gets the PID of bash itself, I just checked

TuxCopter

nvm it's the PID of the shell

ninja'd

zyabin101

2) Easy Install (TM) systems can't be further changed!

DJMcMayhem

@TimmyD sure, but since badges are correlated with rep, I'm sure anyone in the top ten would be at least on the first few pages

zyabin101

I need to know what the golf system I'm using!

3) Easy Install (TM) can't be cancelled!

betseg

@EᴀsᴛᴇʀʟʏIʀᴋ just finished reading, this is hilarious

ais523

18:19

@KritixiLithos in Perl you can construct the ASCIIbet itself in seven bytes, everything from there is just printing it

zyabin101

I wanted to try it, because...

ais523

adding three for say is probably cheapest there

TimmyD

@DJMcMayhem Yeah. You'd be able to get close doing that.

zyabin101

4) Easy Install (TM) has a secret ingredient making your to-be VM do chum: The VMware Tools!

They enforce installing what everyone hates.

@zyabin101 ...but can't.

Kritixi Lithos

@ais523 I see you are also prepared with an answer

feersum

18:22

What I want to do is do head -n to a process and then kill it after N lines are printed.

ais523

well, printing the ASCIIbet is the sort of thing you can do in your head

where does it go from and to in the question? space to tilde?

hmm, I was hoping Jelly had it as a built-in, but it doesn't

zyabin101

Easy Install (TM) has now stole 1024 MB of my memory that I could spend normally, installing Ubuntu all by myself, with no VMware Tools at all.

ais523

I think this comes to five bytes in Jelly

no, four

zyabin101

@TuxCopter Also, you reminded me of getting to work on conlang project.

TuxCopter

:)

DJMcMayhem

18:24

Oh sweet, I recently added something to V that should make that pretty easy

betseg

26

A: Check whether letters of word are in alphabetical order

CJam, 8 bytes lel_$_&= Here is a test harness for all examples in the challenge. This returns 0 or 1 (which are falsy and truthy, respectively, in CJam). And here is a script to filter the word list in the question (takes a few seconds to run). You'll have to copy the word list into the input...

zyabin101

Will continue it right away.

betseg

> lel

ais523

so, the question is, how can you make sure to be first to post an obvious answer?

oh, haha, Jelly's range is broken and only works on integers

this is a common problem with Jelly (random type errors)

betseg

@ais523 reload newest questions every minute?

zyabin101

18:25

@ais523 Would be a good time to call Dennis, but I can't because of the hate inflicted on me by him.

DJMcMayhem

Oh shoot, it should be three bytes but it's four because of a bug

Kritixi Lithos

@DJMcMayhem What's the addition?

zyabin101

Can someone make an Issue/Pull Request for me?

Pretty please? No? Aww.

TuxCopter

@zyabin101 On what?

betseg

Sep 23 at 14:04, by DJMcMayhem

@zyabin101 Nobody said that. Don't create drama for no reason

TuxCopter

18:26

@zyabin101 Do not create drama for no reason

The suspension was looong ago

ais523

actually doing this in Jelly is really quite interesting now, and it's probably going to end up more verbose than some of the other languages

DJMcMayhem

@KritixiLithos a range operator. It inserts every ASCII character between two other characters

betseg

@TuxCopter ninja'd :p

feersum

If no one is gonna tell me how to print the first N lines of output from a process and then kill it maybe I'll ask on Unix & Linux!

Kritixi Lithos

@DJMcMayhem There is no GH push yet

TuxCopter

18:27

@feersum head -n

feersum

But nah, surely the question will be invalid for some reason.

zyabin101

@TuxCopter Jelly

ais523

because I don't think you can express 126 in Jelly in fewer than three bytes

TuxCopter

It autokills the process IIRC

DJMcMayhem

@betseg if you dislike drama, the simple solution is to block those that create it

zyabin101

18:27

Jelly's range is working only on ints

TuxCopter

@zyabin101 You can make one, y'know

You have a GH account

betseg

@DJMcMayhem nah m8 it's entertaining

ais523

@TuxCopter it sends SIGPIPE; that doesn't necessarily kill a process but it does by default

zyabin101

Okai :3

ais523

processes can choose to handle it though

TuxCopter

18:28

@ais523 It kills most processes though

ais523

(although half the processes that handle it just print an error message and exit anyway)

TuxCopter

So I think it's ok

DJMcMayhem

@KritixiLithos it was a while ago

feersum

This SIGPIPE thing isn't working for me since it's a program I wrote and also it's Windows.

Kritixi Lithos

But it's not in the V wiki

DJMcMayhem

18:29

Oh, yeah you're right. I rarely update that. >_<

Right now every insert mode mapping is undocumented

feersum

@ais523 See, I knew it!

MSYS doesn't ship with yes apparently so I can't try that.

ETHproductions

Does anyone think this challenge is too close to the sandboxed ASCII-bet challenge?

ais523

18:31

hmm, would "implement yes" be an interesting code golf challenge?

seequ

Is there actually any use for yes? :P

TuxCopter

brb sandboxing

@seequ Pipe y in programs

seequ

Ooooooh.

ais523

@seequ nowadays many interactive programs have an option (typically -f) to answer yes to all questions they ask by default (there's also often an option to answer no by default, often -q)

but it used to be that if you wanted to use an interactive program for batch updates

you had to set up an automatic yes-answerer to say yes to all its prompts manually

that's where yes comes in

DJMcMayhem

@ETHproductions I think it's fine

ais523

18:33

pipe yes into a program and it'll answer yes to every question it asks

(this is why it outputs an infinite stream of y by default, and where the name comes from)

seequ

Yeah, TuxCopter's answer was enough.

@ais523 Your explanation of polynomial time seems to exclude things like n^2. Am I reading it wrong?

ais523

@Geobits yes; O(n²) means that doubling the size of the problem quadruples the running time

that's a constant factor of 4

Dennis

It's still polynomial though, just not linear.

Ok, so "constant factor" in terms only of doubling, etc. I don't usually see n referred to as a constant factor, that's all.

@Geobits That's because it's constant, not nonstant

ais523

"constant" here means "a number that doesn't depend on n", like 4
