Doesn't everyone love FTL?

Mr. Xcoder

FTL: Faster Than Light

FTL: Faster Than Light is a top-down roguelike space ship simulator created by indie developer Subset Games, which was first released for Microsoft Windows, OS X and Linux in September 2012. In the game, the player controls the crew of a single spacecraft, holding critical information to be delivered to an allied fleet eight sectors away, while being pursued by a large rebel fleet. The player must guide the spacecraft over eight sectors, each with planetary systems and events procedurally generated in a roguelike fashion, while facing rebel and other hostile forces, recruiting new crew, and...

Q: When do moderator elections take place?

I'm really confused on this. I have no idea on several things: When do elections begin? Is there a set time each year? Do elections actually take place each year? Can I vote? Where do I vote? Etc. Can someone please help me?

Thanks anyway, googled

Adám

@MartinEnder OK, I've removed "regex" since PCRE is the grandfather of all the advanced regexes.

I still think .NET is missing. No C# derivs?

Martin Ender

@Adám well, if anything then Perl is...

@MartinEnder Perl is the parent of PCRE on the chart.

Mendeleev

@Jim IMO FTL has the best soundtrack of all the games I've played

Anonymous

@Mendeleev But Bastion and Transistor

Mendeleev

@Mego Have not played those

Anonymous

I highly recommend both. Great storytelling, gameplay, and soundtracks.

Martin Ender

@Adám right, the point is that Perl's regex syntax inspired most modern regex flavours (including PCRE), not PCRE (obviously)

@Mego this. although their narration is even more impressive than their soundtracks.

still need to revisit and finish Transistor though

Anonymous

09:42

@MartinEnder I like the narration, but I'm very much a music guy, so personally I think the soundtracks are their best quality.

Okx

wait, you're not a penguin?

Martin Ender

well, I guess I'd also consider myself "a music guy" at least in terms of enjoying and appreciating it (not so much in terms of making music myself). I was just really impressed by how well the narration flows even if it responds to player choices.

Jim

@Mendeleev I agree

Mendeleev

@Jim yay

Anonymous

@MartinEnder The last level of Bastion had really good narration

Martin Ender

09:45

that ending was phenomenal. best game ending I can think of.

Anonymous

Also I didn't realize at first that the same guy narrated Bastion as Rucks also narrated Transistor. Completely different styles.

Mithrandir

@MartinEnder I ran out of YouTube links. Got any suggestions that I can drop into the Practice Room? :P

Mendeleev

All I know about Transistor is that it's about a sentient sword

Martin Ender

suggestions for?

@Mego oh, just noticed that the release of Pyre is only a month away... maybe that'll motivate me to get Transistor done by then

Mithrandir

Good music. To add some variety to what I listen to.

@Mendeleev It has very different gameplay mechanics compared to Bastion, but it's fantastic

@Mego What's the genre?

Martin Ender

@Mithrandir I mostly listen to post-rock (i.e. mostly instrumental rock), and some math rock and hardcore. some post rock gems that come to mind: youtube.com/watch?v=MAEJ6pX8-W0 youtube.com/watch?v=dne11-PA3JQ youtube.com/watch?v=SBOVkptjJhE

flawr

@MartinEnder do you know year of no light?

Mayube

@MartinEnder hardcore like hardcore rock? Or the genre hardcore?

Martin Ender

09:53

@flawr I do, but I've only ever really gotten into Ausserwelt

Mayube

Xcoder and Mego are the only people on the starboard...

feersum

I clicked the middle one. How is it supposed tob e related to rock?

Martin Ender

@Mayube the genre hardcore/post-hardcore.

Mr. Xcoder

@Mayube And feersum as well

Martin Ender

@feersum how is it not?

Mayube

09:54

interesting, quite a contrast to the other styles you listed

@Mr.Xcoder oh yeah missed that one, nevermind then

feersum

Ah well the first 2 minutes just sounded like an air conditioner.

Mr. Xcoder

@feersum True ^

Martin Ender

@Mayube yeah I guess, although I've found that there's a surprising amount of overlap both in terms of bands and of fan bases. the biggest post-rock oriented festival I know (in the UK) also has equal amounts of bands from those three genres

Adám

I need a .NET collection for an example, what would be a simple (shortest?) way to get one?

CMC: Return a .NET collection.

flawr

@MartinEnder I just ordered that album, the other one I really like is tocsin

Mendeleev

09:56

@Adám Ruby: ->{'a .NET collection'}

Martin Ender

@flawr I don't think I've heard that one. I think I'd listened to Vampyr, but I only just found out that it's a live album.

Mr. Xcoder

@Mendeleev Loophole.

Martin Ender

I might have listened to Nord as well at some point

Mendeleev

@Mr.Xcoder is joke

Mr. Xcoder

@feersum You've summed up hardcore very well

@MartinEnder @Mithrandir I'm a big fan of all things progressive. Dream Theater is by far my favorite band.

Anonymous

09:59

Pink Floyd is up there for me, too

Mr. Xcoder

Progressive like from smooth to hard?

Mithrandir

Looks like I'm definitely talking to people with very different tastes :P

Anonymous

@Mr.Xcoder Progressive as in "who needs consistent, normal time signatures?"

Martin Ender

I guess the only band I listen to that is primarily labelled as prog is Karnivool, but math rock and some hardcore also have a lot of overlap with prog rock/metal

messed up time signatures are the best

Mithrandir

@Mego oooh. Those are awesome.

Mr. Xcoder

The Dance Of Eternity being very prog is practically a meme at this point

But even more strange is when you have more than the standard notes in an octave.

Kritixi Lithos

Do we have a challenge for printing A\nBC\nDEF\nGHIJ\n...?

Mayube

I'm more of an EDM guy myself, been into liquid DnB and japanese EDM lately

Okx

CMC: Do that ^

@KritixiLithos yes we do now

Martin Ender

@KritixiLithos should that last one be GHIJ?

feersum

10:07

26 is non-triangular, so this challenge cannot exist.

Kritixi Lithos

yes... I messed up there

Adám

@KritixiLithos Something like ↑⎕A⊂⍨26↑∊1↑⍨¨+\⍳6?

Kritixi Lithos

@feersum okay then, how about the pattern repeat for 3 alphabets concatenated together? (26 × 3 = 78 which is triangular)

Martin Ender

@Mego you might like scale-the-summit.bandcamp.com/album/the-migration if you're into prog

feersum

Surely some language has a triangularly-sized alphabet.

Adám

10:10

@feersum Hebrew.

Anonymous

@MartinEnder I've heard of them, but I haven't listened to them yet

Kritixi Lithos

@Adám no, the lengths of each run is only one more than the previous

throughout the pattern

Mithrandir

@feersum עברית?

Mayube

what's the smallest triangular number you can add to 26 to make a triangular number?

ah, 10

feersum

Which version of Hebrew alphabet has a triangualr number?

Mayube

10:13

so if you start the alphabet triangle with ABCDE and go up from there, it'll work fine

ABCDE\nFGHIJK\nLMNOPQR\nSTUVWXYZ

@Mayube Alternatively, English alphabet + digits

@MartinEnder 2 is not a triangular number

@Adám Oh, I missed your question. What kind of Collection are you looking for?

Adám

@Mego Anything. code-golf

Martin Ender

is the type of the collection's elements irrelevant as well?

Adám

@MartinEnder Pretty much, yeah.

Anonymous

A (C#) List<int> would probably be easiest: List<int> lst = new List<int>({1, 2, 3, 4, 5});

Adám

10:23

@Mego I'd assume such a simple thing does not require the very latest .NET, right?

Martin Ender

how about "".ToList()?

Uriel

@Mego can you skip the first List<int> for var?

Martin Ender

yes

Anonymous

@Adám Of course not. 2.0 introduced generics.

Anonymous

@Uriel Yes, but I don't like to.

Martin Ender

10:24

why not? o_O

it's visual bloat that adds no additional information

Adám

@MartinEnder Strange. My .NET string does not have a ToList method ⍨

Mayube

ToList() is provided by Linq

Anonymous

@MartinEnder I prefer having the types as part of the definition in strongly-typed langs

@Mego Something off here.I'm on 4.0 and can't create a list.

My inner C programmer won't let me use var :P

@Uriel I was/am trying a solution using the partition function provided by ⊂ with ⎕ML←3

@Mayube Also that

Uriel

@Mego well, c++ has auto

Anonymous

@Uriel Not when I first learned it :P

feersum

10:26

It also has writing the type only once, period.

As in vector<int> lst{1,2,3,4,5};.

Anonymous

@feersum Yeah, C# could do with initializer lists

Mayube

@Adám Works in Mono

auto was introduced in C++11. I learned C++ in 2009, and didn't know anything about C++11's planned features, or the beta implementations (like C++0x).

Adám

@Mayube Yeah, turn out it is the type specification that made troubles.

@Mego It is in APL.

Anonymous

And that's not touching on auto's previous use as a storage class :P

Anonymous

10:35

@Adám Then I can't help you :P I haven't found time to learn APL yet

Anyway, now I have a way to create an array. Thank you all anyway.

Glad to help

Q: Triangular Dependencies

A triangular number is a number that is the sum of n natural numbers from 1 to n. For example 1 + 2 + 3 + 4 = 10 so 10 is a triangular number. Given a positive integer (0 < n <= 10000) as input (can be taken as an integer, or as a string), return the smallest possible triangular number that can ...

@Downgoat wouldn't work in all languages, wouldn't necessarily work if byte limit was 5, also I think you can get smaller than that

Downgoat

Actually i think CGFloat might have smallest number built in brb

CGFloat.leastNormalMagnitude

Doesn't work with such small byte limit though

Wait DBL_MIN works for 7 byte

Dungeon Master was one of the first ever real-time role-playing games, originally released in 1987 on the Atari ST. Among other exciting things for the time, it offered a rather sophisticated spell system based on runes. Your task today is to write a program or function that evaluates the number...

hi @MartinEnder

Martin Ender

hi

Lembik

11:41

do you think it's plausible for code to only extract code from PPCG answers? That is to be able to tell what is code and what is not?

I really want to ask a challenge about this :)

dzaima

@Lembik I did that yesterday with all my SOGL answers

Martin Ender

not 100% reliably. but just taking the first code block should work in >99% of the cases

Lembik

@dzaima Oh! I am not sure what SOGL means though

dzaima

@Lembik it's my golfing language

Mr. Xcoder

@Lembik SOGL is a programming language

dzaima

11:42

ninja'd

Lembik

@dzaima so you wrote code in SOGL to tell whether an input text was code or not?

dzaima

no

I extracted all of the codeblocks with its code

Lembik

@MartinEnder I think I may give it a go as a challenge. Although another challenge that just tries to work out what language something is in might be good too.

@dzaima why did you do that? Was that part of a challenge?

dzaima

no, just wanted to see what are some commonly used function combinations to add 1-byters for :p

Lembik

ok :)

my challenge would need a language that can extract ppcg answers from the web

so may exclude the very esoteric ones

dzaima

11:46

I was thinking about a challenge to find the most used character from a language

Mr. Xcoder

@Lembik So Python, JS, 05AB1E, Ruby and Powershell should compete

Lembik

@Mr.Xcoder cool.

dzaima

Jelly had internet access AFAIK

Lembik

and obviously Java/C etc.

Mr. Xcoder

Also Bash and PHP

Lembik

11:47

and perl!

no one mentions perl any more :)

Mr. Xcoder

Wait, isn't Perl dead ? :P

Lembik

well... more dead than 05AB1E?

What about Assembly :(

Lembik

@Okx that sounds tricky!

Mr. Xcoder

@Okx You golf a web answer in Assembly and I'll give you 200 rep if you get it below 200 bytes.

11:49

sorry no way

200 bytes?

Mr. Xcoder

Yep.

Joke :P

Okx

i will give you a 500 rep bounty if you get below 200 bytes :P

dzaima

SOGLOnline SOGL technically has internet access

Lembik

hang on.. is this assembly just to get a url?

as in wget in assembly?

Mr. Xcoder

@Okx Ok, I will steal JonSkee's rep from SO and will give you 500k if you get it below 200 bytes

Okx

11:50

i will hack SE and give you 10 mil if you get it below 200 bytes

Mr. Xcoder

Should start learning assembly :)

Lembik

hmm.. so how hard is it to fetch a url in assembly?

A: download file from url in assembly language in osx

Download from where? If assume you want to download from a WWW, it is pretty simple task: Using sys_socketcall (eax=102) create a socket, then connect to the desired URL, then send a HTTP command: http_request db "GET /file_url HTTP/1.1", 13, 10, 13, 10 Read the socket by lines until you re...

just call curl or wget from your assembly code :)

Mr. Xcoder

@Lembik So about 2k bytes :)... Sounds easy

Lembik

hmm.. it's an interesting question

maybe actually a nice code-golf question in the end

but is there an assembly hello world?
