Do they? I mean...yes, all part of the plan.

TimmyD

Hah, nice.

Adnan

@quartata Either Ç or ç should work

arda

ok, c++ version working fine.

quartata

@Adnan Does it vectorize?

betseg

4:07 PM

NASA completed the James Webb space telescope. Woo!

TuxCopter

TIL this exists

Adnan

@quartata Yes

an array of characters also works

Geobits

Wow. Florida is saying they had 6.5M early votes cast. That's over 50% turnout from the entire state before election day even started. To put that into perspective, turnout for 2012 and 2008 were both 62% total.

TimmyD

Yeah - I read that Florida had more early votes this year than the entirety of their votes in 2000.

Geobits

Might have something to do with the 4-6 hour lines at some polling stations the last time around :/

quartata

4:26 PM

@Adnan Why doesn't this output anything in 2sable? "asdf"Çvy

Adnan

@quartata Oh, it doesn't work in 2sable

quartata

:/

Adnan

Ç was broken for a long time in both 05AB1E and 2sable

it only works in osabie

@quartata if it helps, the 05AB1E equivalent "asdf"ÇJ works :p

quartata

Yeah I know

But an extra byte :(

TimmyD

Quickly glancing at this ^^ conversation, I thought the posts were the same person.

Adnan

4:30 PM

for which challenge is this?

quartata

How does ë work by the way?

doesn't seem to work the way I thought it did

arda

uuugh its stuck here for like 30 mins

Shebang

Welcome to VS ;)

arda

I've been using it for 5 years and I hated installing it on every format and every upgrade

Adnan

@quartata Seems to work for me :)

4:32 PM

Someone has a Wordpress botnet. Here's a subset of the IPs used to attack: gist.github.com/turbo/56a42c3f99bde8c0df2bfb7b3d5009ef . You might want to block them if you have a public facing website. If you are under attack, redirect user-agents containing "wordpress/i" to 403.

Geobits

@ConorO'Brien Nifty indeed :D

quartata

@Adnan Oh I forgot to close it with }

TuxCopter

@mınxomaτ A Wordpres botnet o_O

Adnan

Ahh, okay :p

quartata

Huh still doesn't seem right

Does it work properly with strings?

arda

4:34 PM

@mınxomaτ would cloudflare take care of that for me or should I block them by hand anyways?

Sp3000

@mınxomaτ I don't have a Wordpress on a site of my own hosting (at least, not any more), but thanks for the heads up (really appreciate it!)

quartata

"I voted"vyÇÈi"blue"ë"red"}yJ

mınxomaτ

@TuxCopter isc.sans.edu/forums/diary/Wordpress+Pingback+DDoS+Attacks/17801

quartata

pretend red and blue are the appropriate ansi codes

arda

@Sp3000 I don't think that it is what the issue is

mınxomaτ

4:34 PM

@Sp3000 No, it doesn't matter if you have WP. It uses WP to attack.

Sp3000

Oh, I thought you meant it was trying Wordpress exploits. Right.

arda

I think that there is a botnet, that is tons of WP users, that probably DDOS sites

mınxomaτ

@arda You can add them to your CF firewall.

Adnan

@quartata Hmm, what output are you expecting then?

arda

@mınxomaτ all by hand? ouch

I could use CF api though

mınxomaτ

4:36 PM

If you are not usually under attack, it doesn't really matter for you.

quartata

@Adnan It should output blue followed by the character if the character's code point is even and red followed by the character if it's odd

mınxomaτ

But atm it has enough capacity to take down a pretty beefy nginx proxy.

Adnan

@quartata Ahh, okay I understand

When you perform Ç on a 1-length string, it still returns an array

quartata

Woops.

Also your string compressor seems not to preserve capitalization

“€íÃ¼“ gives lowercase i at the beginning

Adnan

@quartata You can use the sentence-case operator

But you can also use „IÃ¼ :)

arda

4:48 PM

ok I think I'm getting somewhere

quartata

And in the end it's still 28 bytes

Conor O'Brien

@Geobits I'm trying to start lo:ve, but I need something called hg. what on earth is that?

Sp3000

Sounds like Mercurial

quartata

@ConorO'Brien Mercurial

Geobits

I just apt-getted it, so I'm not sure what the install process is elsewhere.

Conor O'Brien

4:51 PM

alright, so it seems to be mercurial

Geobits

I thought they had a self-contained installer for any OS though.

Conor O'Brien

thanks y'all

@Geobits installer, yes. compiler, no

Geobits

That's odd.

TimmyD

apt-get, apt-install, apt-makesandwich

Geobits

Oh, did you grab the source from bitbucket or something?

Conor O'Brien

4:52 PM

I used the windows installer

quartata

@Adnan This has a lowercase v I just noticed

Geobits

Huh. They must've changed it in the last couple years. I used to use it on win and never needed mercurial for anything.

quartata

So it's going to be 29 bytes throwing in titlecase

Conor O'Brien

why can't everyone just use git -.-

Adnan

@quartata Oh, that's unfortunate

quartata

4:54 PM

0000000: 8449 c3bc c776 79c8 6922 1b5b 3334 6d22  .I...vy.i".[34m"
0000010: eb22 1b5b 3331 6d22 7d79 e74a            .".[31m"}y.J

Adnan

Maybe you can shave some bytes of by doing something like ["red", "blue"][Ç%2]

quartata

What I had in the end

@Adnan I'll try that

TimmyD

@ConorO'Brien apt-git

TuxCopter

hg-git

Adnan

@quartata Actually, you don't need the mod 2

Conor O'Brien

4:57 PM

what are these hyphen gits

quartata

@Adnan Oh, do you have modular indexing?

Adnan

since it uses modular indexing

TuxCopter

@ConorO'Brien hyphen-git

TimmyD

curl weights;
make protein-shake;
git good;

Conor O'Brien

thank you I read the chat without a ping

TuxCopter

4:58 PM

@TimmyD ._______________________.

yuo spleled git gud wrong

TimmyD

@TuxCopter I also didn't spell it "curl w8s" because I use English.

2

TuxCopter

watiz english

betseg

But git gud is a meme

Sp3000

(I'm starting to really hate the word "meme"...)

TuxCopter

In French même mean same

Conor O'Brien

5:01 PM

but meme and même aren't le même

TuxCopter

@ConorO'Brien Accents are most of the time ommited

The word time is most of the ommited also >_>

mbomb007

@TuxCopter omitted

arda

:33385394 I got into trouble for that in the past :/

betseg

Lol (removed message: meme means breast in Turkish)

TuxCopter

@mbomb007 It's a valid word

arda

5:03 PM

(was checking memes on 9gag, someone saw it (that it was saying "loading memes"), and stuff didn't really go well)

TuxCopter

one day I will ommiting wors and ltters

Conor O'Brien

not anyday soon

:P

mbomb007

@TuxCopter omitted is, but not ommited.

TuxCopter

ah

typo ¯\_(ツ)_/¯

Sp3000

@arda @betseg Personally I think once or twice is fine, e.g. if you realise something you said was wrong and nobody's replied to it yet. Just as long as it doesn't become a habit.

quartata

5:06 PM

He was referring to the content of the message

Not deleting it

TuxCopter

TFW your YTB comment is the most liked of a video

arda

@Sp3000 I wasn't talking about his message; I was talking about the fact that the meaning of memes in turkish got me into trouble when viewing memes, as in advice animals and stuff, not private parts of body.

Sp3000

Oh right, nvm.

Adnan

@quartata btw, I got this now: ”IÃ¼”v"blue""red"‚yÇèyJ

arda

@Sp3000 nw, my message could be pretty easily misunderstood

mbomb007

5:09 PM

FTW: For the win
WTF: What the f---
TFW: That feel when
TWF: ??? (That was funny?)
FWT: ???
WFT: ???

betseg

FWD: forward

mbomb007

this is FWT, not FWD

quartata

@Adnan Oh wow. You can post that yourself if you want: just substitute blue for <esc>[34m and red for <esc>[31m

TimmyD

I've seen "WFT" as "Well, f--- that."

Conor O'Brien

Wft-> well f--- that?

Wft ninja

TuxCopter

5:12 PM

y u ninja me

mbomb007

Google suggests FWT: Flying With Turban

TimmyD

I can dig it.

mbomb007

I think we can come up with better.

Conor O'Brien

TuxCopter

github.com/npm/npm-expansions

betseg

4 stars left until abusing thing reaches 100!

Yay my first time 200 rep in one day!

TuxCopter

npm-expansions have exactly 444 contributors

arda

5:22 PM

holy crap I think I'm finding the number wow

btw @betseg do you think they'd let me reach the maths guy if I called the ogretmenevi he's staying at?

Sp3000

What do you mean by "I think I'm finding the number now"?

Kritixi Lithos

How are you finding the number?

betseg

@arda probably

mbomb007

My site rep is a palindrome

arda

I think I managed to find a mathematically good and fast way to brute force the number, but we'll see that in a few hours I guess.

betseg

5:25 PM

"computers can't solve" he said

Sp3000

"brute force"... uh...

You probably still need a computer for the first part though, right? Or at least that's what I was doing

mbomb007

@Sp3000 What challenge?

Sp3000

Definitely not for the factors of 2^b-1 part though

6 hours ago, by betseg

@ASCII-only http://i.hurimg.com/i/hurriyet/98/770x0/581ef49e18c77313b0e83760 a=*huge number*; n=*an integer*; Bn=*n 1s* ((10^n-1)/9); Bn%a=0; b=2^n-1. Questions: n=? What are b's factors?

TuxCopter

Computers can solve everything...

Sp3000

Only with the right algorithms - you sure ain't going to be able to brute force this though

Shebang

5:28 PM

Definitely not the factors

TuxCopter

And if silicon-based computers can't solve it, wait some decades to have quantum computers ¯\_(ツ)_/¯

Sp3000

Yeah, bit stuck what to do there, apart from the initial factors of the form 2^d-1

arda

ok, I'm slowly progressing, and I think this approach might work

I'll need more ram at this rate though :/

Derp, that was kilobytes, ignore that.

betseg

downloadmoreram.com is the solution

Sp3000

... would it work if n was 74 digits though?

arda

5:32 PM

my screen looks like matrix lmao

self note: don't ever enable visual output on brute forcers

betseg

It actually slows the process down

arda

IT does, severely

feersum

Did you guys already find n?

Kritixi Lithos

Bn=*n 1s* ((10^n-1)/9); What is s and what is B?

Sp3000

I think I have n

(hence my comments about 74 digits)

betseg

5:35 PM

B<sub>n</sub> = (10^n-1)/9

Bn % a == 0

@KritixiLithos ^ and ^^

Kritixi Lithos

And we have to find B's factors, right?

Sp3000

According to betseg, little b's (2^n-1), which is the hard part :/

betseg

2^n-1's factors damn ninja'd

Sp3000

Also @feersum darn you for posting the Seed cop during exam period for me :/

feersum

awwh

arda

5:37 PM

@betseg wait, what exactly is that? Can you explain what I exactly need to find in turkish?

feersum

Dennis ought to be able to get it

Now he's practiced inverting some PRNGs.

betseg

@arda first 93 factors of 2^n-1

That's it

arda

n being?

betseg

((10^n-1)/9)%a==0

arda

a being 97388839913164773144180653700430045648016870068507697797313816794125988183817453‌6316361975757?

betseg

5:39 PM

Yup

arda

oh, gotcha

Kritixi Lithos

What is the value of n that you got?

arda

ok, fun fact, the brute forcing algorithm I was testing (I'm mildly high so it's probably wrong but still) got stuck on 93 character difference

Kritixi Lithos

Post this as a challenge on PPCG :P

arda

Happy 93th year of turkish govt :P

betseg

5:42 PM

@KritixiLithos then steal the answer any get ₺100,000 lel

Sp3000

@KritixiLithos Starts with 7250379854

(is what I had)

arda

@betseg then spend it all on steam, yay!

Geobits

That's a lot of steam. Water is cheap.

arda

(my steam account is worth around 14.5k turkish lira, double lel (yes, I'm disappointed with my life))

steamdb.info/calculator/76561198034299068/?cc=tr

(I spent less than 1k usd on it, but well, I get most stuff on sales and from bundles)

betseg

?cc=us => about $9000

TuxCopter

5:45 PM

7957€ o_______O

arda

In my defense, I've had this account for 6 years

Nathan Merrill

it says that my account is worth $698 (at the lowest sale), but that's certainly not true

arda

well, 6 years in 17 days: steamcommunity.com/id/ardaozkal/badges/1

@NathanMerrill yeah, it doesn't count sales or bundles.

Nathan Merrill

I think a lot of that comes from humble bundles

Kritixi Lithos

It says that I don't have steam

arda

5:47 PM

@KritixiLithos that's for the best

Steam is hell. Can I get a refund, please?

Kritixi Lithos

;)

arda

remembers that he has to put games on steam greenlight I-I'm joking steam is the best woo

TuxCopter

Mine is only 166€

Nathan Merrill

my price per hour on CivIV is 0.03 cents :)

oooh, found a better one: Terraria at 0.02 cents

arda

I have 2000 hours on diablo 3 (I used to be addicted to that). The game costs 40usd. 0.02 cents per hour.

TuxCopter

5:50 PM

I have 105 hours on Robocraft o_O

Geobits

No idea how many I put into D3, but I play on PS4, so...

Nathan Merrill

yeah, I'm no where close to that. My top game is 600 hours on Dota 2, which is 0.00 cents per hour

betseg

40 dollars per hour on Kerbal Space Program. In my defense, I play games that require less brain in school time.

arda

@betseg any recommendations of games that don't require too much brain power?

@TuxCopter robocraft used to be pretty fun, then they made it a moba, then they changed it again

daHugLenny

I have 595.3h on Geometry Dash, 0.01 cents per hour

TuxCopter

5:53 PM

I stopped playing Robocraft after the stupid overhaul adding some superop weapons

I couldn't play a game anymore without being nuked (literally) by 5 people :/

arda

@TuxCopter same :/

Shebang

I have a $4200 problem...

Nathan Merrill

@TuxCopter is that because of power creep, or PTW mechanics?

TuxCopter

Lock-on missile launcher

feersum

Anyone have any phone screen interviews tips?

Kritixi Lithos

5:54 PM

Use a PC

Geobits

@feersum Have a computer with a fairly quiet keyboard nearby :P

Nathan Merrill

aka, does everybody have access to nukes in Robocraft?

arda

@NathanMerrill ptw, ish

Nathan Merrill

and they simply didn't balance them right?

Sp3000

Set yourself up properly beforehand in a nice, quiet place because wasting 2 minutes trying to find headphones is not a good idea

TuxCopter

5:55 PM

The game is badly balanced

Nathan Merrill

@arda what's "ish"?

TuxCopter

I am very high level, but since the big update money is really hard to gain

result: I have low-level weapons

arda

@NathanMerrill you need to win to earn ig money, and you can't win easily without putting rl money in game.

Nathan Merrill

so, its basically a PTW mechanic

:/

arda

well you get money if you lose too, but much much much less

TuxCopter

5:57 PM

If you win, you ear a big bonus and the gains are multiplied by 2 if you are vip

arda

vip players get 2x money and xp too

TuxCopter

And if you lose, to gain things you need to make kill

Nathan Merrill

right, but the need to grind to get good items doesn't remove the ptw

TuxCopter

To make kills you need to have stupidly powerful weapons

Or have 1e6 SMGs

Nathan Merrill

@arda oh! looking at my game list, one of my favorite brain-not-needed games is Burnout Paradise

arda

5:58 PM

@NathanMerrill oh! I have that, that's amazing.

Shebang

Is it on Steam or Origin?

Nathan Merrill

yeah, its on steam

Shebang

I remember playing it years ago

Ooh, maybe once I pay off this month's bill.. ;)
