It's the final sprint... and half your team is off ill. You're working late, just making your last commit for the day, looking forward to... why have the lights turned off?

The actual issue is that I accidentally de-referneced JDK-8, meaning that there were -no- libraries.

Григорий Перельман

But why do you have a variable of type String named stdin

Destructible Lemon

feersum

OK guys, who has the google fu

I'm trying and failing to find a reference for a strange "globbing"-like feature in windows cmd

Some commands seem to accept "<" as a pattern for a string that does not include a period

Mistah Figgins

@feersum "globbing"?

feersum

E.g. dir "<o" will list files that end in o.

And don't have a period in them.

I mean like in Unix there are "glob patterns" which have . or * as wildcards.

I don't mean really like Unix shell globbing where a list of files is expanded in the command.

Another example cd "f<" will change the directory to some directory that begins with F, if there is one.

I wonder what possessed me to type dir "<<" in the first place...

ASCII-only

Weird, dir "<" doesn't appear to show files, only directories

Jan Dvorak

4:20 AM

I'm going to attribute that to suicidal dendencies

feersum

@ASCII-only All of your files ust have extensions then.

< doesn't match strings with . in them.

ASCII-only

But << does?

Plus <f matches f.f.f

ATaco

The "Sum STDIN" challenge can now be solved with:

#import math
\r?\n/+/
(?#input)

feersum

It seems my theory of what < does was not very accurate

The challenge to find a reference on this behavior remains...

Григорий Перельман

@ATaco Why is there a \r?? It's golfier to remove it.

ATaco

4:24 AM

(Well you don't need the \r, but I'm testing on a Windows system)

feersum

You can also use > in a pattern, but it seems rather useless so far.

dir ">" only matches . and ..

ASCII-only

@feersum Found it

feersum

@ASCII-only Nice

They miss cd in their list of commands that can use this.

ATaco

Likewise, the following gets the product of STDIN

#import math
\n/*/#input

Григорий Перельман

Actually, why not just bypass unix/windows confusion entirely and use \s+?

Not in the golfed version

ATaco

ASCII-only

@ATaco under-the-hood?

ATaco

4:47 AM

mult<a,b> and similar are usually used to just get the result, where as the actual function call itself is a*b, not that mult<a,b> wont work just as well for a function call. a+b is the only one that doesn't actually need one.

Can anyone explain (or a link) How PPCG works?

Okx

@SagarV Thanks for asking in chat before posting an answer! PPCG is a site where you can post challenges (generally code-golf) and get solutions for that challenge. The most common type of challenge is code-golf, which means users try to make a solution to the challenge in as few bytes as possible. Any language is allowed.

Thanks @Okx for the quick response.
So, what are all the things I have to care before posting Q/A?

Destructible Lemon

I actually was able to chat with someone on omegle and I invited them to the site

betseg

11:28 AM

Wow

Destructible Lemon

They live in the america place so I can't actually interact with them that much though so :/

@betseg you discuss questions and then ignore the questions

which are mostly just sleazy crap anyway about rating and crap

betseg

@DestructibleLemon ?

Destructible Lemon

When you use omegle, don't go straight to text chat

click the button below it and discuss questions

betseg

Actually I've never used Omegle

Jan Dvorak

ome-what? That troll farm still exists?

@DestructibleLemon wow thats interesting could you tell me more

Erik the Outgolfer

@JanDvorak I tried to talk on Omegle. I failed. I have only found predators so far...

SIGSEGV

@EriktheOutgolfer Predators? like what?

Jan Dvorak

@SIGSEGV pedophilia and such, I'd guess

Erik the Outgolfer

@SIGSEGV People wanting to talk in other places with me.

I guess they don't want me to be anonymous.

SIGSEGV

ohh

Erik the Outgolfer

11:37 AM

Yeah, I'm not easily lured.

Basically I think I am constantly finding bots.

See here for an example.

SIGSEGV

Hmm

Should we make an omegle bot which will catch bad dudes and bots on omegle

Erik the Outgolfer

Is Omegle even a real thing? (I haven't tried video)

SIGSEGV

maybe

Erik the Outgolfer

Tried discussing a question, and viewing discussion, but a stranger is always getting disconnected. Omegle is borked.

I made a Python abomination

def add_state(init=None):
    if init is None: init = {}
    state = type("State", (object,), init)()
    def decorator(f):
        def wrap(*args, **kwargs):
            return f(state, *args, **kwargs)
        return wrap
    return decorator

@add_state({"n": 0})
def f(s):
    s.n += 1
    return s.n

print(f()) # 1
print(f()) # 2

yet strangely I kind of like it

Hi

@KritixiLithos Like this: sort key={|a|[#a]}. It's similar to Python.

SIGSEGV

Would making a programming language which consists of a sound file where the abscissa value of each peak makes the source code, a good idea

Jan Dvorak

12:34 PM

it would still likely be easier to code in than Malebolge

SIGSEGV

Did you mean: Malbolge?

Jan Dvorak

Either would work :-)

fəˈnɛtɪk

@SIGSEGV you appear to have lost the word "be" from your sentence.

SIGSEGV

Umm.. what?

fəˈnɛtɪk

The sentence should end with "be a good idea?"

SIGSEGV

12:41 PM

Ohh I see

system("stty cooked echo"); ...How did cooked echo taste like?

I mean, considering unix commands as edibles, then cooking them, is obviously not a good idea

Okx

I do it all the time

Q: Division and remainder

This challenge, while probably trivial in most "standard" languages, is addressed to those languages wich are so esoteric, low-level, and/or difficult to use that are very rarely seen on this site. It should provide an interesting problem to solve, so this is your occasion to try that weird langu...

code-golf arithmetic division

AdmBorkBork

@ГригорийПерельман I'm not familiar with dart, so I don't know what that's meaning. In actual PowerShell, it would bankers-round the 0.5 to 0, so you'd get 11 again. I'm not sure what dart is doing.

@NewMainPosts I can't believe that challenge has never been asked

@Fatalize I'm surprised it isn't quite as trivial as it sounds

Q: Queueing With Friends

You're with your best bud, Jim, at the amusement park and as your favorite ride comes into view, you and Jim exchange glances. Naturally you race to get in line. Unfortunately he wins because you're a golfer and he plays a real sport (sorry friends). In fact, you're so far behind that you and Jim...

Big News: Google is starting to distrust certificates issued by Symantec (Thawte, VeriSign, etc.) due to security concerns.

ELI5 why?

> Summary
Since January 19, the Google Chrome team has been investigating a series of failures by Symantec Corporation to properly validate certificates. Over the course of this investigation, the explanations provided by Symantec have revealed a continually increasing scope of misissuance with each set of questions from members of the Google Chrome team; an initial set of reportedly 127 certificates has expanded to include at least 30,000 certificates, issued over a period spanning several years. This is also coupled with a series of failures following the previous set of misissued certifi…

TL;DR: symantec didn't vet their certs good

and many many certs they gave were bad

i reloaded chat, userscript gone ;_;

@betseg wait PPCG userscript?

betseg

yes

Cole

@KritixiLithos go for it; i'm going to update the spec to reflect what appears to be community consensus

@KritixiLithos I'm going to delete my comment and just add a comment reflecting the update. Thank you for your patience.

@DJMcMayhem showerthought: hitting "need healing" as genji should instakill you

Григорий Перельман

@Riker I can get behind this initiative.

Riker

and the "more support" is a pita also

iirc that one only shows up for support classes anyway sooo

SIGSEGV

When has this community become Arqade

Григорий Перельман

I'm fine with healing Genji as long as he is not halfway across the map and jumping around like an idiot. Genjis and tracers are the only people I can't reliably hit with Ana shots.

Riker

2:25 PM

there's your problem /s

@SIGSEGV it hasn't

90% of the time it's not about games

@ГригорийПерельман zenyatta homing missile OP

Григорий Перельман

My friend is a hard-code Zenyatta main, and I never solo queue, so I end up never playing zen.

Riker

ah

he's really fun

Григорий Перельман

Like, 150 hours Zen 10 hours rest combined.

Riker

lol

tha'ts a bit excessive

Григорий Перельман

I don't have a main, though I tend to play supports I have pretty even times with almost everyone.

Except Zen and Sombra

Screw Sombra

Anyway, I gtg I have class.

Q: How do we know that our question can graduate from the sandbox?

I have a couple of sandbox posts that have been there for a while. I have not posted them yet, though, because I don't know if they are ready... How does one know if their ideas are ready to graduate from the sandbox?
