Q: Why is the no deadline bounties post not featured?

List of bounties with no deadline That post is not featured for some reason and I am wondering why? It is a very useful and important community post. I think it should be perm featured like sandbox. (I know that in sandbox people keep going back to retexture it). But still. Shouldn't it be featu...

@DJMcMayhem pull pls

DJMcMayhem

@Riker Huh?

Destructible Watermelon

has @Riker made new language called pls?

Downgoat

@DJMcMayhem I think maybe he mean to ping Dennis and accientally you because both username start with D

DJMcMayhem

Well, he did just fork one of my repos, but I don't see any PRs

Riker

00:19

@DJMcMayhem I made PR?

github.com/DJMcMayhem/ThePeoplesPython/pull/5

@Downgoat no I meant to ping DJ but good guess

@flawr amen

lol @Downgoat thanks for the responses/comments

Pavel

How to match a literal backslash with regex in Java: \\\\

Destructible Watermelon

ok um

I left dwarf fortress running in the background and now my dining room/tavern is filling with water O.o

Riker

lol

Downgoat

okay @Riker @KritixiLithos (anyone else?) who can beta test my github app I think I got working online install link here: link

Destructible Watermelon

I probably should have seen this coming too

I think subconsciously I wanted this to happen

DJMcMayhem

00:22

@Riker Oh, huh it didn't show up in my notifications

Riker

hm

@Downgoat woot

I'll try to test in a minute 1 sec

Downgoat

(sorry for all pings)

Riker

lel idc

Downgoat

very little done but making progress quick

Destructible Watermelon

ok how do I try to save my dorfs? anybody got any ideas?

Downgoat

00:23

also, I'd like to request to try not to exhaust API quota :P

oh no that version crashes D:

Riker

@DestructibleWatermelon ya dont

@Downgoat D:

Downgoat

Riker

@DestructibleWatermelon yeah they're dumb like that

Destructible Watermelon

00:27

actually I've unforbidden it just for the lols

Riker

@DJMcMayhem ... can you merge :P

giving me write access would also be nice if you could

Downgoat

user165474

Anyone know how to get Linux Mint KDE to set the JVM back to 1.8? I updated the system earlier and now it's at 1.9, but I don't have 1.9 installed.

Pavel

00:41

Install 1.9

It'll be fun

user165474

Riker

@Downgoat chedr?

Downgoat

@Riker No swift

okay fixed bug... reuploading

DJMcMayhem

@Riker Not at computer >_<

Riker

ah k

@Downgoat install app now?

ATaco

00:47

I'm very pleased with how RProgN2 is coming together.

Downgoat

@Riker I'll have to get new link lemme uploda

Riker

kk

Downgoat

@Riker also, basically only repo and your profile listing work. Mostly what needs to be tested is A) error handling and B) login

Riker

ah okay

Downgoat

@Riker @KritixiLithos sorry for broken link, here is fixed one: i.diawi.com/m1WSCM

lemme know if it works

user165474

00:52

great now my java 8 doesn't work either ;_;

Riker

"gitgoat cannot be installed at this time"

@Downgoat

user165474

darn it, I put the two arguments for ln in the wrong way

user165474

Now I just deleted my Java 8 JRE.

Downgoat

okay, try going to Settings > general and to bottom, do you see a "developer" or "profiles" or "device management" section

Riker

checking

@Downgoat @ConorO'Brien

sorry ckb didn't mean to ping you

oh wait don't have xcode on this mac

Conor O'Brien

00:56

@Riker same

Riker

@Downgoat sorry, something came up, will test later

Downgoat

that's okay, will take me some time to wrestle with weird apple distribution system

Riker

ah ok

Pavel

@AlexL. No you weren't actually supposed to get Java 9

Matthew Roh

I'm working on a new programming language in GH, anyone wants to do it with me?

Pavel

00:58

It's the sketchy early alpha to end all sketchy early alphas

Matthew Roh

(Probs helka, he pinged me about it)

Pavel

No large project will run on it normally.

user165474

@Pavel I know, it's not stable yet, but my system updater decided it would be a good idea to try to get it, so now I need to manually set it back.

Pavel

It's fun to mess around with, I suppose.

user165474

I suppose, yes.

user165474

01:02

But it's now my default JRE, which means I can't run Minecraft :P

Pavel

I got Minecraft to work on Java 9

It was slow and crashed often

user165474

oh

user165474

Well, my Java 9 JRE isn't installed properly, so it can't even create the VM.

orlp

did really no one even like this? youtube.com/watch?v=NMKOY9hZEd8&feature=youtu.be I think it's insanely impressive

Pavel

sudo apt install openjdk-8-jdk

@orlp It's cool, liked it.

I think a lot of people were at work when you posted that, so youtube might not have been possible what with the whole audio thing.

user165474

01:07

hahaha I fixed it by using the hackiest solution ever

user165474

(probably not the hackiest)

Matthew Roh

Anyone recommend me of the name of my new stack-based 3D rendering programming language?

Pavel

@AlexL. Eh, what'd you do?

@MatthewRoh 3D rendering? Wut.

orlp

@MatthewRoh 3d rendering as in minecraft or as in unrestricted real vectors?

Matthew Roh

Hmm

user165474

01:09

Download the RPM, use alien to turn it into a .deb, run the package installer, and then use sudo ln to link wherever which java is to the file in etc/alternatives and then link that to the new file.

Matthew Roh

@orlp Unrestricted real vectors

Pavel

@AlexL. You symlinked Java 9 to Java 8?

user165474

@Pavel No, I just symlinked the thing to point to Java 8 instead of Java 9.

Pavel

Ok. See, I already came up with a hackier solution than yours ^^

Matthew Roh

are you talking about JVM

Pavel

01:15

JRE

Matthew Roh

Okay then

user165474

@Pavel Sure, I could also symlink Java 9 to 8

Great, that helps me a lot

Pavel

Your code chicken core appears to be broken

It isn't fixable.

You have to reinstall it

Maybe I haven't been to Iceland because I'm busy dealing with YOUR crummy code.

LegionMammal978

I... I... I did it

I constructed a regular heptadecagon in a circle:

Matthew Roh

LegionMammal978

01:57

With labels removed for clarity:

@MatthewRoh ?

Matthew Roh

that looks very very hard

LegionMammal978

@MatthewRoh It took about an hour total

Matthew Roh

oh really

ATaco

You used circles to make an almost circle.

I'm legitimately impressed.

LegionMammal978

And I had to look at this GIF many, many times:

It's over a minute long, so I had 2 open

Staggered timewise

@ATaco Overall, the construction used 39 circles, 12 lines, the 2 points specifying the original circle, 46 intersection points, and 17 line segments

Wheat Wizard

02:09

@Okx Hey I just noticed that whatever script you used to update the indefinite bounties page flagged a link to user changed 1000000000's name to 4. I fixed the problem I just thought you might want to know.

LegionMammal978

@WheatWizard Wait, a script was written to update it automatically?

Wheat Wizard

@LegionMammal978 I don't think so. I think he just ran a script across the entire thing to clean up the markdown. Then again I don't know.

Maltysen

@wat why is there even code for that...

to format it as "from"

wat

don't know, it's likely just a part of a general time formatting library

ATaco

02:22

Github actually uses the local system time for commit times, which means you can make a new commit 30 years in the future or past by changing your computer's settings and Github wont question it.

Question: In my GitHub iOS app, I need to show two important pieces of info about a given user. One is their name, what should other be?

Matthew Roh

username?

Downgoat

03:20

yeah, it shows name/username together

ATaco

Show their name, again, but in a different colour.

AKA, I have no idea.

Matthew Roh

I have an idea what it is

the user's email address

Downgoat

what if the user has not supplies email

Matthew Roh

oh right

ATaco

In which context is this? Is there some information you can specify about the context?

Downgoat

03:23

lemme get a screenshot

Matthew Roh

He said "GitHub iOS app"

ATaco

EG. if it's comments, the time the comment was posted might be a good idea.

Downgoat

if you notice you'll see "Label" below their username

I have 0 idea on what should go there

Matthew Roh

As I said, If the user has email, email. else, blank.

Downgoat

Unfortunetly I don't have info about email

and to retrieve it could be around 100 API reqs

Matthew Roh

oh

yey

now pls dont make it ios 10 only

please set sdk versoion to ios 8.0+

I am honestly quite proud of UI

it looks pretty nice

goat test it now

also what do you think of my ui

dk0.us:8082/transactions/check/in

Downgoat

I have no idea what it does but it looks nice

ATaco

Oh no, Floating Point Arithmatic

Downgoat

05:37

is it inspired by google's material design?

ATaco

4.000000000000007

Matthew Roh

@Downgoat It is definitely material design

mınxomaτ

@MatthewRoh It would have to have floating labels in the inputs to be full material.

ATaco

How do I delete rounding errors?

Matthew Roh

but you should have used polymer for that, right?

wat

05:41

@Downgoat yes

@MatthewRoh Polymer does not work with rails.

I used materialize

Matthew Roh

huh

Rails? Do you mean Ruby on Rails?

wat

yup

Is this nice logo for GitGoat

DJMcMayhem

05:54

I'm just disappointed that it isn't GoatHub

Downgoat

@DJMcMayhem that would imply an app which shows lots of videos and memes of goats. Which is a different app I'm making

my god who needs 6400x6400 size png

wat

call it "GoatHub for GitHub"

and then just brand it as GoatHub everywhere else

mınxomaτ

Yes. Gotta satisfy the redundant department for redundancy.

Pavel

@Downgoat That's actually really good.

ATaco

GoatHub, the place for goats of all shapes and directions to meet and bleet.

Pavel

05:57

It fits with the actual GitHub logo.

Downgoat

Okay so like 83% done with GitGoat app now :D

Poll: GitGoat or GoatHub

ATaco

The most polarizing vote of the decade.

@Downgoat Blocked for me, but put in a vote from me for GoatHub

Destructible Watermelon

@Downgoat downgit!

ATaco

06:08

I vote Downgit.

Pavel

Scratch that, Destructible's suggestion is infinitely better.

It also won't confuse the heck out of people who are looking at the name

How do I load string objects as data-processing-target in Processing.js

Kritixi Lithos

@Downgoat 10/10

@MatthewRoh Did you already add Processing to the webpage?

Matthew Roh

I did

also I'm gonna use bitballoon until I find a proper hosting site

Kritixi Lithos

What about GH pages?

Matthew Roh

06:15

:\

GH would be nice too

but for custom URL, I need to make yet another organization

Kritixi Lithos

You can create a repo and have ghpages for that repo

Matthew Roh

Oh really?

I'm just gonna use BitBalloon tho

Q: Bitflip-resistant composite numbers

Sometimes, when writing a program, you need to use a prime number for some reason or other (e.g. cryptography). I assume that sometimes, you need to use a composite number, too. Sometimes, at least here on PPCG, your program has to be able to deal with arbitrary changes. And in circumstances conv...

I just disassembled an Active Speaker System made by Sony.

I think it was unnecessarily hard. Sony was being a total ASS

You could also say it was a pain in the ASS to take apart

Matthew Roh

06:32

can I use eval in processing.js

Pavel

06:42

All them newbies with their Processings and such. Back in my day, we learned programming with Python.

Jan Dvorak

Python? We used C. Not even C++. C.

Pavel

That was a joke, since I'm fifteen.

Matthew Roh

Once upon a time people used FORTRAN

and TI-BASIC

DJMcMayhem

@Pavel oh, you poor thing :P

Pavel

I actually skipped intro to CS, so I never ended up learning python particularly well.

Now I'm a Java person.

Jan Dvorak

06:45

Of yourse, you wouldn't write the FORTRAN in a fancy text editor with autocomplete features and live debugging. You punched holes in predefined positions, sent the stack to someone with a computer, and if you got the program wrong, you'd have to buy a new stack of punch cards.

Pavel

And also pay for all the cards you wasted after it dumped core.

DJMcMayhem

@JanDvorak I have no idea how old you are, so I can't tell if you're serious or joking :P

Pavel

Wait, FORTRAN came after punch cards, by like a lot.

Jan Dvorak

Only if you could afford it, of course. The poorer were lucky if they got the line number back.

ATaco

RProgN 2 has made good progress

8{8`**}*C

Prints an 8 by 8 of asterisks

Now can anyone in the audience work out why

Jan Dvorak

06:50

it's stack based, int * block is iteration, backtick quotes a character, and C ... prints?

I mean ... int block *

ATaco

You kind of had it

C calls, int block * makes a new block which is n times that block

Jan Dvorak

oh.

Ew.

ATaco

; iterates.

Print is implicit

Qwerp-Derp

I need French help

How do you say the sentence "On weekdays, I wake up at 7 o'clock" in French?

Pavel

TuxCopter is asleep

Kritixi Lithos

06:55

@Downgoat My iPad is iOS 8 and not 10

ATaco

@JanDvorak what part of that is unappealing, is like to see if I can make it better

DLosc

@Qwerp-Derp Je ne sais pas. (And that's about all the French I know.)

Jan Dvorak

I would prefer int block * to evaluate the block int times.

Kritixi Lithos

@Qwerp-Derp My try: Les jours de la semaine, je me reveille à 7 heures

ATaco

Why an implicit evaluate? I could make it implicit and keep an explicit operator as well.

Jan Dvorak

06:58

Golfscript uses ~ to evaluate strings/blocks

ATaco

I'm quite explicitly not writing a golfscript clone

Qwerp-Derp

Is it "De lundi à vendredi, je me lève à sept heures."?

Basically "From Monday to Friday, I wake up at 7."

ATaco

RProgN is trying more to be "Golfy RPL"

Kritixi Lithos

lève is "get up", reveille is "wake up"

Pavel

RPL?

ATaco

07:00

en.m.wikipedia.org/wiki/RPL_(programming_language)

Jan Dvorak

@Qwerp-Derp Looks good to me, but that doesn't say much.

@ATaco mobile wiki? Yuck.

Qwerp-Derp

@KritixiLithos "reveille" is also reflexive, right?

ATaco

I was on my phone, don't judge me

Kritixi Lithos

@Pavel That or he's in school

Pavel

@JanDvorak I use wikiwand: wikiwand.com/en/RPL_(programming_language)

Kritixi Lithos

07:02

@Qwerp-Derp Oui

Jan Dvorak

Why?

Pavel

It looks nicer and is easier to read.

And I can search by double-tapping control.

ATaco

The flow of control used to closely match RPL's, but it became a pain to golf, so I switched to blocks and functions that work on blocks

Jan Dvorak

I like the floating X mouse pointer they have.

DLosc

@flawr Re: Iceland president article--how does that guy have a 97% approval rating? Must be nice to live in a country where (nearly) everybody likes their president...

Pavel

07:05

@JanDvorak That's the cursor for when clicking closes something

Jan Dvorak

which is why I like it.

Pavel

I thought you were being sarcastic

I use an extension which automatically redirects wikipedia to wikiwand.

wat

I used to use wikiwand. my school blocks it for some stupid reason

Pavel

>_>

DJMcMayhem

07:23

@DLosc I'm pretty sure that's a parody site, like "The Onion"

Qwerp-Derp

Can I say "Je preparé pour quinze minutes pour l'école"?

Pavel

Putin has an 87% approval.

Qwerp-Derp

@KritixiLithos I need halp

DLosc

@DJMcMayhem Ha! Well, if Wikipedia is reliable... they have the same figure. I would have checked out the source cited, but of course it's in Icelandic.

DJMcMayhem

Oh, wait actually I googled it and apparently the pineapple thing is real

DLosc

07:28

Interestingly enough, it appears he was elected on only 39% of the vote.

Matthew Roh

Fun fact: Kim jong un has an 100% approval

Pavel

The actual approval rate is 67%

DLosc

The difference being that as far as I can tell, Guðni Jóhannesson has not been threatening/arresting/poisoning anybody to boost his numbers. :P

Matthew Roh

@DLosc Well kim jong un did tho

I think we are getting off-topic

Pavel

The 67% would appear to be actual approval data, it comes from a combination of people who have escaped NK being asked whether they thought that people they knew approve of KJU, private UN surveys, etc.

Though the error bars on that 67% are probably huge.

Matthew Roh

07:35

oh really

Pavel

Yes

Matthew Roh

Would making people output RED ZONE in audio too much for a challenge

For people who doesnt know it:

Red Zone Full version MP3

►

Pavel

Do they have internet access?

Matthew Roh

sure

Pavel

Otherwise, the challenge is equivalent to 'Inflate an arbitrary deflate stream'

With internet access, sure seems intresting.

You have to specify exactly which sites can be accessed, how it should be played, etc.

Matthew Roh

07:39

:P

1. Play the vid
2. type awesome
3. click loop
4. profit

Pavel

Nah, that's silly.

Why randomly add bytes for no reason?

Playing the audio should be fine.

No need for anything else.

Matthew Roh

Sure

Pavel

Might be a dupe, but I don't think so.

Post in the sandbox.

Matthew Roh

hmm

theres not much questions on audio

Pavel

Still, you want to sandbox it.

Matthew Roh

07:44

Yeah

I'll sandbox it later

Like tomorrow or so

Qwerp-Derp

How do I say "I leave the house at around 10:30am"?

I know how to say it exactly, "Je quitte la maison à dix heures et demie", but I don't know how to add the "around" bit in
