Sometimes I google for valid URLs

quartata

Yeah like adfly

CalvT

@M.A.R. you probably want to remove this comment apple.stackexchange.com/questions/282165/…

quartata

I flagged it as not constructive and it hasn't been resolved yet surprisingly

I thought the Apple mods were usually pretty fast

Thomas Ward

slackers they are :P

NobodyNada

20:19

\o @QPaysTaxes

nice!

quartata

PPCG mods are the worst. There's this bird, a guy in a scarf, an neo-cubist doorknob and that kid who keeps harassing Mr. Wilson

Thomas Ward

@QPaysTaxes drops a massive fifty-ton tower of obsolete Linux disks on your head

Kaz Wolfe

@ThomasWard he's talking about... that one, I think.

NobodyNada

@QPaysTaxes especially the ones who are mods on both

Kaz Wolfe

but there definitely are worse ones across SE. I know a couple.

Thomas Ward

20:21

i'm still dropping the obsolete disks on him lol

CalvT

@ThomasWard only fifty tons? Surely there's more obsolete linux disks than that :P

Thomas Ward

@CalvT yeah we turned them all into a neutron star though

so if he WANTS a neutron-star-density set of obsolete disks on his head...

@QPaysTaxes what about fifty neutron stars

Kaz Wolfe

as a wolf, i just sit here and bark at spam until it goes away.

Thomas Ward

or ten billion

@KazWolfe or end up stuck in the spam traps and can't get out without bothering me for help.

:P

NobodyNada

lol, we had a cat who would do that

Kaz Wolfe

20:23

hey, it's not my fault spam tastes good.

CalvT

Careful @QPaysTaxes this is what Thomas looks like atm :D

Byte Commander

NobodyNada

He'd walk into anything that was open

He once got stuck in our little shed thing and we could't find him for several days

And the only thing we ever caught in skunk traps was him

Kaz Wolfe

it's also not my fault i don't have a diamond to help myself out of things yet

i'm curious as to what would happen if @ThomasWard were to try absinthe.

Byte Commander

@QPaysTaxes me neither, but it is about things on heads

Thomas Ward

20:26

@KazWolfe do you want the universe to end?

Kaz Wolfe

actually, yes.

Thomas Ward

there's a spike pit over there you can jump into if you want to end that. But I mean all the things in all the universes to end.

it's like ripping apart space-time, giving me absinthe.,

Kaz Wolfe

Yeah, I mean all things. Across existence.

Thomas Ward

I would know - i've tried it before :P

Or was I?

Kaz Wolfe

wut

NobodyNada

20:29

...?

Nope

Kaz Wolfe

no?

CalvT

Only Macklemore I know is the moped one

Downtown I think?

... ~~what~~ nvm, I thought it said "people are the best security you can have"

CalvT

Oh wow - of all the companies it could have been

Kaz Wolfe

20:33

cybersecurity 101: now being taught in 3rd grade

NobodyNada

Sure, they're necessarily a part of the best security you can have, but they're also the worst part

Kaz Wolfe

yeah, that works.

DavidPostill

@QPaysTaxes Ninja'd :)

Byte Commander

probably you should replace the leading space with a \b

NobodyNada

afk for lunch

Byte Commander

20:38

I think it was -R for sed...

for grep it's -E for extended or -P for PCRE, but I am also never sure about sed

       -r, --regexp-extended

              use extended regular expressions in the script.

lowercase -r then

Byte Commander

can sed recurse at all?

man sed does not say anything about recursion, so I guess no

first the script/pattern. file is last

NobodyNada

-back

...how did I get a dash in there?

@QPaysTaxes Is that the same as strongly or statically typed, or different from both?

@QPaysTaxes Sure

@QPaysTaxes Not AFAIK

latest dev?

@QPaysTaxes seriously? nice!

demo.ctn?

quartata

@QPaysTaxes Statically means verified at compile time; strong means no coercion

They're different

quartata

So it's dynamic

It is

NobodyNada

BTW i get a warning:

quartata

Dynamic, strong

NobodyNada

20:58

> warning: optimization level '-O5' is not supported; using '-O3' instead

quartata

That's what most interpreted languages are

NobodyNada

Not Python or Ruby

quartata

That's not what that means

Dynamic means it's verified at runtime

It says nothing about how types are enforced, just when

It's one part of an overall typing discipline

NobodyNada

> Static type checking is the process of verifying the type safety of a program based on analysis of a program's text (source code). If a program passes a static type checker, then the program is guaranteed to satisfy some set of type safety properties for all possible inputs

quartata

Fun fact: C is technically static but weakly typed

NobodyNada

21:02

This is interesting

ArtOfCode

#impostorsyndrome

that's not a spec, it's documentation

NobodyNada

Would someone with an Ubuntu server mind hosting FireAlarm for a bit?

The copy on the Raspberry Pi is having some problems, and I'm working on updating Swift to fix them, but I don't know how long it'll be before it's stable

quartata

21:18

I could probably put it on Heroku

There's a buildpack for Swift I think

Does it have a Package.swift?

NobodyNada

@quartata Yes, but if you're talking about this library, I don't think that one would work

because I can't just run swift build to compile it. It uses the C library libwebsockets, so the build command includes some compiler and linker flags

CalvT

@NobodyNada if it's not too technical I could set up an EC2 for it

NobodyNada

@quartata @CalvT both of those options would be awesome!

ArtOfCode

I prolly could, but I don't have any Swift binaries or tools on mine at the moment

NobodyNada

thanks!

It's not hard to set up -- download Swift, unpack the tar, add it to your PATH, download libwebsockets, run cmake . && make && sudo make install && sudo ldconfig, then you're good to go

ArtOfCode

21:24

links? if nobody gets to it before me I can have a look when I've finished this mountain of chips

NobodyNada

Here's the Swift download link: swift.org/download (unpack the tarball and add <unpacked directory name>/usr/bin to your PATH)

Here's the libwebsockets download link: github.com/warmcat/libwebsockets (run cmake . && make && sudo make install && sudo ldconfig)

Here's the FireAlarm link: github.com/SOBotics/FireAlarm (run build.sh)

quartata

I've almost got it one second

NobodyNada

thanks!

quartata

Creating ⬢ firealarm... !
 ▸    Name is already taken

:/

NobodyNada

I actually have to go now; sorry about that

CalvT

21:28

If Heroku doesn't work out I've got a EC2 initializing

NobodyNada

I'll see you either tonight or tomorrow

ArtOfCode

it's a race to the fire alarm

CalvT

Lol :D

ArtOfCode

BANG and they're off! quartata is going for the straight Heroku strategy; solid strategy that, all his attention on one server. CalvT has opted for Heroku with an EC2 backup - we've seen that work before but it can fall down if he divides his attention too much.

quartata

dafuq

NobodyNada

21:31

I may have a few minutes, but I cannot promise it, and I may disappear without warning

quartata

What version of Swift do you need?

ArtOfCode

299.7.81.5

quartata

somehow I doubt that

ArtOfCode

good luck

NobodyNada

@quartata 3.1 or newer

ArtOfCode

21:32

okay I might be exaggerating. 299.x will work.

quartata

I'll need to modify the building so that I don't need sudo

How do I execute the resulting binary?

ArtOfCode

Minor setback there for quartata - we see this every year, Heroku's lack of sudo availability always catches someone out. What do you reckon quartata's chances of getting this modification done quickly enough are, Brian?

quartata

silence

NobodyNada

@quartata just run it, although you'll probably want to set the ChatBotEmail and ChatBotPass environment variables to the email and password

Send me an email at <my username>@sobotics.org and I'll give you the creds

(although, maybe with proof that it's actually you emailing me :)

quartata

Same capitalization?

NobodyNada

21:39

No, all lowercase

ArtOfCode

it's an email, it shouldn't matter

NobodyNada

NobodyNada

quartata

21:40

@NobodyNada That is mostly definitely not me

NobodyNada

considering the email came from [email protected], that makes sense ;)

ArtOfCode

@quartata with a From header of [email protected]? No shit :P

quartata

@ArtOfCode I'm your sock I thought

ArtOfCode

the term is exobrain

NobodyNada

...is it this one?

ArtOfCode

21:41

bonus SE-geek points if you get that reference

NobodyNada

quartata

No I'm jmac's exobrain

@NobodyNada yes

I was too lazy to put in a proper body

NobodyNada

Ironically, I'm about to go to a Beavers baseball game

ArtOfCode

@quartata no you're not, you're not labelled properly :P

jmac labels his exobrains to keep track of them

(the rival colleges in Oregon are the Beavers and the Ducks)

@ArtOfCode Dead pixel?˙ Having a dead pixel would just suck so˙very much.

ArtOfCode

@KazWolfe I already have one, but the one in your message is moving and is therefore an impostor

quartata

@NobodyNada Hmmm

I'm not sure what technically the home directory is

I'll test

ArtOfCode

and you can also tell by screenshotting them, and it's only dead if it doesn't show up in the screenshot

quartata

@NobodyNada I can pass flags to the buildpack compile via SWIFT_BUILD_FLAGS btw

so it should work

CalvT

@ArtOfCode 192 is a wonderful resource but I cba to pay for it so ur safe :P

ArtOfCode

@CalvT they don't have me :P

CalvT

@CalvT there's probably more than one of me in the UK :P

@Andy bonus SE-geek points for you

DavidPostill

@ArtOfCode Age and location narrow it down a bit :)

CalvT

@ArtOfCode Yeah 192 has 156 of you :D

NobodyNada

@quartata Great! BTW, you'll also probably want to make a file called location.txt containing quartata heroku or something. And if you could sign up for Redunda, I'll add you as a collaborator. Then you can make an instance and put its key in redunda_key.txt

Thanks!

quartata

22:01

One thing at a time: the buildpack is having trouble

ArtOfCode

@DavidPostill aye, you'd get it down to a handful

CalvT

Well I've places to be. Chau all

DavidPostill

@ArtOfCode Are you a company director?

quartata

ah there we go

heroku doesn't have cmake are you freaking kidding me

ArtOfCode

@DavidPostill hey if it serves as misdirection, yes ;)

DavidPostill

22:11

@ArtOfCode lol. Cabbage :)

ArtOfCode

@DavidPostill cabbage?

ArtOfCode

@DavidPostill making dog noises up the wrong leafy thing there

DavidPostill

@ArtOfCode Hmm

quartata

@NobodyNada cmake doesn't appear to be installed on Heroku and the process for getting it on there appears to be fairly involved so I wouldn't hold your breath that I can get it up today

Once I can do that though everything else should be in place. I wrote pre_compile and post_compile hooks to manage libwebsockets and set up the build flags hopefully correctly
