@Quill I have a question aobut websockets: what port should I use for websocket

if I use 80 it'll interfere with HTTP

idk what to use then

Quill

just use a port that isn't reserved

I usually use 9999 or 8090

Eᴀsᴛᴇʀʟʏ Iʀᴋ

Can a mod unfreeze a room for me?

Upgoat

Dr Green Eggs and Ham DJ

3:32 AM

@EᴀsᴛᴇʀʟʏIʀᴋ Oh Bai. Sorry it didn't work out, I'm busier than I thought. Maybe some other time though.

Upgoat

@DrGreenEggsandHamDJ wai is bai capitalized?

Quill

It's a proper noun. @EᴀsᴛᴇʀʟʏIʀᴋ's real name is Bai

Upgoat

or maybe he was referring to his Bai

@DrGreenEggsandHamDJ are you east coast, or west coast, or middle-coast, or not-even-in-the-us?

Dennis

TIL that other countries don't have coasts.

Upgoat

3:48 AM

@Dennis O_o you just learned that? :P

Dennis

Also, LOL @ middle-coast.

Quill

Upgoat's been hanging upside down too long... he can't think straight

@Upgoat I am a teacher. Not sure if great.

@Quill Or Goat West.

Upgoat

@Dennis huh, didn't expect that to be true :| but I'm sure you're a great teacher! What subject do you teach?

Real Analysis

Upgoat

@Quill is a nooblet like some sort of chicken ._.

@Dennis brb, trying to apply outgolfing dennis meme with real analysis.

TypeError: Cannot read property '7' of undefined

what does this even mean ._.

Dennis

> undefined[7] = '7?'
x VM3124:2 Uncaught TypeError: Cannot set property '7' of undefined(…)

The fix I was going to propose isn't working.

Upgoat

@Dennis make sure you're not in strict mode. then do: undefined = []; undefined[7] = '7?'

Quill

3:59 AM

var a = {}; a['cat'][7] = 'dog'

Dennis

Neither is working for me. Is Chrome's console strict?

Quill

not by default

Dr Green Eggs and Ham DJ

@Upgoat Middle-coast.

Quill

oh, I read it as set.... | var a = {}; a['cat'][7]

Upgoat

This looks sound right?:

if  -> "if" expr codeblock if'
if' -> elif
       else

elif -> "else" "if" expr codeblock if'
else -> "else" expr codeblock

@Quill a classic.

Upgoat

4:28 AM

wow, the node debugger was actually useful for once

Should Cheddar allow the syntax: if foo bar() which is equal to: if (foo) { bar() }

Quill

depends whether A) no braces on if condition is okay and B) whether inline conditions are acceptable

Upgoat

@Quill if foo { bar } is okay atm

Quill

nakedsecurity.sophos.com/2014/02/24/…

missing braces cause problems

Upgoat

ah yeah, I read about that

Bálint

5:47 AM

@Upgoat Java: spend 3 days writing, spend 1 week debugging, and you get a 200 line long code

Leaky Nun

6:01 AM

javascript eval infinite loop, anyone interested?

write some code that will call eval with the same code

@Bálint

Mars Ultor

@Bálint But that's nothing

Mars Ultor

6:23 AM

@LeakyNun eval(`${($=_=>eval('eval(`${(console.log($+"")||$)()}`)'))()}`)

Too lazy to golf

Without showing function as string: eval(`${($=_=>eval('eval(`${$()}`)'))()}`)

@LeakyNun Or if implicit eval counts, then molarmanful's Bling Quine will work: $=_=>`$=${$};$()`;$()

levanth

Is there a max character count per Line in MySQL? Or am I just blind and dont see the error in my sql statement? `JOIN queue, ticket_state
ON queue.id = ticket.queue_id and ticket.ticket_state_id = ticket_state.id`

Mars Ultor

@levanth Yeah, it's 65536

@levanth Where do you declare (?) ticket?

@levanth Per line of the query? No

@Quill But I don't use braces on single line statements

@Quill It's like forgetting a semicolon, just the compiler doesn't warn about it, but wouldn't it be solved by running it through a linter?

Leaky Nun

6:42 AM

@MarsUltor How does it work?

Mars Ultor

@LeakyNun Implicit function toString (which gives its source code)

@LeakyNun The bling quine makes it a lot clearer

levanth

@MarsUltor I just sent the corresponding lines where I got an error code but I was blind ^^ I tried: JOIN queue, ticket_state but without the () for the table references

Leaky Nun

@MarsUltor Which version are you using?

levanth

the correct statement would be JOIN (queue, ticket_state)

Mars Ultor

@levanth Uh, what error code?

@LeakyNun ???

Leaky Nun

6:44 AM

@MarsUltor of javascript

Mars Ultor

@LeakyNun ES6

levanth

@MarsUltor just a general syntax error on line XYZ

Mars Ultor

but only because lambdas are a lot shorter

Leaky Nun

@MarsUltor and how may I confirm it works?

Mars Ultor

@LeakyNun Use the one with the console.log, or use the bling quine: $=_=>`$=${console.log($+"")||$};$()`;$()

or use alert if you don't want it lagging

Leaky Nun

6:48 AM

@MarsUltor I mean, I don't have es6 javascript

Mars Ultor

@LeakyNun This should be correct: eval('($=_=>eval(\'eval(\\\'${\\\'+$()+\\\'}\\\')\'))()')

Leaky Nun

@MarsUltor Wouldn't it be shorter if you peel of the first eval? It gets executed anyway

Mars Ultor

55 mins ago, by Leaky Nun

write some code that will call eval with the same code

Leaky Nun

Wouldn't ($=_=>eval(\'eval(\\\'${\\\'+$()+\\\'}\\\')\'))() call eval?

Mars Ultor

Oh yeah

Then you don't need the inner eval

also whoops no template string

Leaky Nun

7:02 AM

($=_=>eval('\'${\'+$()+\'}\'))()

Mars Ultor

@LeakyNun ES5 has no lambdas

Leaky Nun

($=_=>eval('\'${\'+$()+\'}\''))()

Mars Ultor

@LeakyNun ($=function(){console.log('($='+$+')()')||eval('($='+$+')()')})()

^Infinite quine

Leaky Nun

nice

Mars Ultor

Without the console.log: ($=function(){eval('($='+$+')()')})()

Whoops, keep forgetting you have only ES5

Leaky Nun

7:07 AM

well

no

I use firefox console

and I've no idea what version that is

Mars Ultor

Firefox/Chrome are always the latest

Leaky Nun

but lambdas do work

Mars Ultor

Chrome is slightly ahead

They've supported most of ES6 for ages

Leaky Nun

I see

Mars Ultor

($=_=>eval(`($=${$})()`))() and ($=_=>console.log(`($=${$})()`)||eval(`($=${$})()`))() then

@wizzwizz4 How did you manage to get here if you only saw it a few minutes ago? At the very least, your journey should have been as long as the time it took for you to see the signal.

@Mego I was heading here anyway.

And that would require traveling at the speed of light, in which case I have more questions.

It's a mix of different smells. Most of it is just stale air: some computers stay days on a shelf, even if it's a new model. If you have ever stepped into an old room or sat in a car which hasn't been opened for days, you'll know what that smells like. Other than the air, there's a lot of plast...

Answering it didn't required any knowledge of RC-s

wizzwizz4

@Bálint It's not, but I can't discuss what to do with it with @Chenmunka because, as far as chat is concerned, they're not a mod.

D'ya think I should change the parent site on @Chenmunka's chat profile?

Bálint

You're a mod, I think you can auto-close it

If I understand it correctly

@Bálint I need to discuss it.

@wizzwizz4 couldn't @Katenkyo remove his own message? If it had happened?

wizzwizz4

@levanth I, as a moderator, would have to BURN the message.

Burn it in fire.

levanth

Then move it to its own chatroom, then burn the chatroom...

Then pipe it to /dev/null then burn /dev/null

Q: How did debugging software run without memory?

Katenkyo

@wizzwizz4 First time it nearly happened to me, will serve as a lesson : always check were your alt+tab leads you

@levanth Even if I deleted it, I would have to change the sudo password instantly

levanth

@Katenkyo well of course but just to be sure that you can delete messages after you posted them here.... Otherwise @wizzwizz4 would have burned the whole room down

Anonymous

Knowing a password without knowing what it's the password for doesn't really do much

wizzwizz4

@wizzwizz4 That's an assumption that will more than likely be false

All I would know is that Katenkyo uses insert password here for one of their passwords (assuming also that they wouldn't say "oh shit I just pasted my server's sudo password", which is reasonable)

@wizzwizz4 A moderator abusing that power to hack people's accounts would get noticed quickly and banned so hard that the reverberations from the banhammer could be felt across the blogosphere.

In fact, the impact from the banhammer upon the internet would be so strong that some of the weakly-attached portions would fall off. Like MySpace, or those internet-connected refrigerators.
