@AlexA. So I'm not the only one that carries brass knuckles, just hoping for something like that to happen?

Alex A.

Of course not

quartata

Have we had a challenge about calculating the permanent of a matrix?

Alex A.

No, or at least not by that name

El'endia Starman

I've never heard of a permanent of a matrix.

Alex A.

Permanent

In linear algebra, the permanent of a square matrix is a function of the matrix similar to the determinant. The permanent, as well as the determinant, is a polynomial in the entries of the matrix. Both permanent and determinant are special cases of a more general function of a matrix called the immanant. == Definition == The permanent of an n-by-n matrix A = (ai,j) is defined as perm ⁡ ( A ) = ∑ σ ∈ S n ...

@AlexA. /me tries to make a pun on "Immanuel"

Alex A.

:P

Good luck and godspeed

quartata

It comes up in the context of #P problems a lot

Alex A.

The immanant is something I'm not familiar with

@quartata I hear that trends on Twitter among mathematicians

quartata

@Alexa. Yeah I've never heard of the immanant until now

El'endia Starman

Oh, the permanent is just the determinant without sign changes.

@quartata that's your job

Alex A.

Oh jeez, GitHub set me up for automatic notifications on 31 repositories because I was given push access. :|

I'm going to have a billion emails

El'endia Starman

Oooh, TIL about the #P complexity class. en.wikipedia.org/wiki/Sharp-P

zʏᴀʙiɴ101

@AlexA. These repos are CROWDED? D:

Alex A.

Crowded?

zʏᴀʙiɴ101

People very frequently add issues/pull requests/comments/commits on them?

Alex A.

6:22 PM

Oh, yeah.

It's all of the official repos for statistics stuff in Julia

One of the several reasons I've been fairly absent lately is that I've been contributing to Julia and the Julia ecosystem

Oh Alex is back

o/

finished migrating?

Might have been hit by fireworks flak.

Alex A.

When I was about 18 I accidentally set my girlfriend's sister's dress on fire with a firework

Geobits

6:31 PM

> "accidentally"

Uh huh

Alex A.

>_>

Fatalize

important question is: did she drop the dress?

Alex A.

Yes, but I didn't look.

Fatalize

too busy taking pictures

( ͡° ͜ʖ ͡°)

Geobits

Wait, was this an older or younger sister? This matters. >_>

Alex A.

6:33 PM

Younger, by several years

Fatalize

Nevermind then

Alex A.

She must have been about 14

muddyfish

Im not saying anything about other's preference, only thats not for me :)

Alex A.

You mean you don't like setting young girls on fire?

Alex A.

@muddyfish Nor am I. Sometimes fireworks just... get out of hand.

@Optimizer Gross

muddyfish

@AlexA. I know the feeling

Optimizer

fishes don't have fur.

Rainbolt

You have worms too?

Optimizer

or back

Alex A.

6:35 PM

Do fishes not have backs?

Geobits

Fish have backs.

Optimizer

its tail

not back

muddyfish

better?

Alex A.

Nice!

Geobits

6:36 PM

@Optimizer No, not the tail. Where the dorsal fin is... along the spine.

Optimizer

so both sides is back?

Fatalize

Strangely on topic

Alex A.

o_O

Fatalize

Borrowing from German Backfisch ‎(“teenage girl”, literally “fish for frying”)

Geobits

How many dorsal fins do your fish have? The ones I've seen only have them on one side.

Fatalize

6:37 PM

Business Cat

Wait what

Optimizer

@Geobits oh. i have no idea.

zʏᴀʙiɴ101

@CᴏɴᴏʀO'Bʀɪᴇɴ Well, come what may.

Dr Green Eggs and Iron Man

While I was at fireworks last night, one of them went sideways and they set the ground on fire.

Business Cat

Cᴏɴᴏʀ O'Bʀɪᴇɴ

@zʏᴀʙiɴ101 I don't know what that's supposed to mean in reference to a PR.

Fatalize

back of a fish, and setting a teenage girl on fire

Dr Green Eggs and Iron Man

Delayed it all by like 15 minutes.

Geobits

@muddyfish Well that muddies things a bit.

muddyfish

@Geobits it sure does

It's surprisingly hard to talk in chat and play a game of civ 5

zʏᴀʙiɴ101

6:38 PM

@CᴏɴᴏʀO'Bʀɪᴇɴ The mandatory Travis build is ongoing.

Alex A.

@muddyfish :P In my defense, they were my girlfriend's dad's fireworks, and he thought it was pretty funny.

Cᴏɴᴏʀ O'Bʀɪᴇɴ

@zʏᴀʙiɴ101 I know that.

Alex A.

(It was not intentional)

Geobits

@muddyfish I find it hard to do that even without talking in chat. civ44life

zʏᴀʙiɴ101

> Hang tight, the log cannot be shown until the build has started.

Well, maybe not ongoing.

Optimizer

6:39 PM

All these etiquettes and rules that mods make for the chat .. along with chat freeze and what not. And then Alex returns on chat...

Alex A.

@Geobits Wow, they sure have made a lot of Civilizations games.

@AlexA. and no degree

only a back of worms

Geobits

@Bálint Needs better font before anything else imo.

Alex A.

@Bálint I like the idea, though the tour won't actually be useful until we get site specific text.

Bálint

@AlexA. You know, this is why it's called promotion ad

Alex A.

6:44 PM

? I don't understand

Optimizer

you are promoting a generic tour page?

Geobits

@Optimizer I'm pretty sure you can get medicine for that instead of relying on birds.

Bálint

@AlexA. It's going to change if ppcg promotes, isn't it?

Optimizer

@Geobits we don't have any doctors in the farm here

zʏᴀʙiɴ101

@Bálint Maybe not?

Geobits

6:45 PM

@Bálint Not necessarily

Bálint

codegolf.stackexchange.com/tour

zʏᴀʙiɴ101

The tour is only benefit to those new to this site.

Bálint

@zʏᴀʙiɴ101 Yeah

Alex A.

@Bálint As Geobits said, not necessarily. Our site-specific text is "under review"; there's no guarantee that any of it will be implemented.

Geobits

@zʏᴀʙiɴ101 I don't know that it's actually a benefit to those new to this site.

Bálint

6:46 PM

@Geobits Yeah, this was the first free font I remembered

PhiNotPi

@Bálint Good concept. To make it look better, have the path travel somewhere through the middle of the ad instead of just around the edge. Also, consider adding a compass rose and a textured background.

Geobits

@Optimizer You should see about fixing that. It would be much less traumatic than having Alex burn the worms off with fireworks.

Optimizer

@Geobits llamas really dont get enrolled into medical colleges..

Geobits

Why not? Do they not study hard enough?

Bálint

@PhiNotPi I originally wanted to add a texture to the background, but I think it's better if it's simpler

Geobits

6:48 PM

Or is it a lack of extracurriculars?

Optimizer

they cant write entrance tests well with those hooves

Geobits

Oh, good point. I've seen how goats type too, so I imagine it's hard for any hooved animal.

Bálint

What do you think about the font?

Optimizer

wow, one bad font after another

Bálint

@Optimizer Yeah, that's what I thought

Geobits

6:50 PM

If you're going to make it a pirate map, use some sort of handwritten, piratey font

Ya know, like Comic Sans

<_<

Bálint

@Geobits ...

Huh, I don't really like this one

Optimizer

he was joking.

Bálint

@Optimizer It's not comic sans

It's "Lindsey" I think

Optimizer

how about a monotype font since the site is mainly coding based

Alex A.

Everyone knows pirates love to golf

zʏᴀʙiɴ101

6:54 PM

@Optimizer @Bálint Inconsolata!

PhiNotPi

@Bálint Other images for your consideration: previews.123rf.com/images/casaltamoiola/casaltamoiola1205/… or thumbs.dreamstime.com/x/cartoon-treasure-map-15028828.jpg or s-media-cache-ak0.pinimg.com/736x/ec/85/81/…. My point is you can add a textured border with the inside of the map still being a solid color for readable text.

Bálint

@PhiNotPi The problem isn't with the readability

If you design a banner, you need to look at the page it will be at

SE's design is very simple

I'll add a slight gradient to it

Anyone knows a good typeface for this? I'm out of ideas

Take out the "you" in the second line

Also, "out our tour" looks awkward

Eᴀsᴛᴇʀʟʏ Iʀᴋ

@Downgoat y u no merge PR or even comment on it

Cᴏɴᴏʀ O'Bʀɪᴇɴ

@Bálint there are hundreds of free, superior fonts

Martin Ender

@Geobits s/\bour\b/the/ would probably fix that. That said, this ad would only make sense if we finally get a useful tour page.

Bálint

@MartinEnder Yeah, I only post it after that

Geobits

Yeah, that would be an easy fix. But agreed on the tour thing not being helpful atm.

@AlexA. gg. I set the lawn on fire yesterday. :/

we have a pool though, so water put it out.

Bálint

I made it simpler

Geobits

I think it could also use some texture in the background. Just something light to make it look more like parchment or something.

Maybe some rips, creases, that sort of thing, too.

I read that before. I just disagree :P

If you're going for "pirate map", make it look like a pirate map.

Not something that came out of an inkjet printer.

muddyfish

why not post and delete it so high rep people know about it?

@Geobits Because this

looks like a real sandbox

muddyfish

how doesn't it?
its got sand right?

not custard or anything?

It's clearly not supposed to though. It looks cartoony. The map looks like it's supposed to be a map, but doesn't.

I agree with the others, This was a surprisingly difficult challenge. Partially due to the requirement to have adjacently connected pixels of the same region type, but also due to the aesthetic challenge to make the regions look like a map of countries.

Wow. Converting a DateTime to a string and back in C# causes loss of precision. That makes no sense whatsoever.

myDate != DateTime.Parse(myDate.ToString())

Business Cat

Where is the precision lost?

Rainbolt

Conversion from DateTime to string

i.e. in DateTime.ToString()
