The Nineteenth Byte

@BrainSteel If you post a link text, the link isn't visible, and a # at the end doesn't break the link, so you can use #@username to make it ping without being visible unless they hover over it

Alex A.

7:06 PM

@BrainSteel Like [ this ] ( http:\\ @BrainSteel ), but with no spaces and // instead of \\

Do it on unprintable characters like Phi does or on small punctuation like I do

trichoplax

(but I think it's better if there's a real link in there so clicking on it takes you somewhere)

Alex A.

^ never thought about that, agreed

Hmm. No onebox ping...

Alex A.

But I love that jimmy23013 is just "Jimmy" XD

Hmm...

That's the idea.

This is magical.

7:10 PM

Isn't it though?

trichoplax

Nope. # breaks oneboxing

BrainSteel

Super secret ping conversations incoming?

Alex A.

Incoming? They're already here.

trichoplax

I pressed random on xkcd and got the emojic 8 ball. That seems meta

<a target="_blank"> is better than using JS to open the link.

PhiNotPi

No onebox ping?

Alex A.

What is this one box? Does it rule them all?

BrainSteel

One box to rule them all, one box to find them, one box to bring them all and in the darkness bind them...

trichoplax

Certain sites (important ones like wikipedia and xkcd) have a preview in chat when a link is posted

Alex A.

Important ones, like xkcd. :D

BrainSteel

7:14 PM

Also, image files.

BrainSteel

I'm on a list now!

Alex A.

@PhiNotPi I love it.

@BrainSteel Yes, and the NSA curates it.

BrainSteel

It's delightful. The suspense every time is immense. The wheel never lies.

PhiNotPi

I also randomized spinning times a little bit.

So you never know when it's going to stop.

BrainSteel

7:18 PM

Yet, we always know where...

PhiNotPi

Is it room-description-ready?

Alex A.

I would say so

BrainSteel

Room description?

Alex A.

The description of The Nineteenth Byte will feature the Wheel of Blame

trichoplax

Just below the room title, top right

PhiNotPi

7:20 PM

I could still add more people... sirpercival, LegionMammal, flawr, etc.

BrainSteel

Ooooh.

Alex A.

@PhiNotPi You could randomize each spin to a subset of the people.

PhiNotPi

I have no clue how to do that, though.

trichoplax

You could make it 2d, spinning horizontally and vertically

Alex A.

Well we have friends in high places, so if you ever figure it out, I'm sure the link could be updated.

@trichoplax Nausea city

I need their icon URLs, though.

NinjaBearMonkey

It has icon URLS

PhiNotPi

okay

@NinjaBearMonkey Your name gets truncated on the left to "NinjaBearMon." Makes me imagine someone saying it in a Jamaican accent.

@trichoplax Whats a onebox?

Alex A.

@Calvin'sHobbies I asked the same question and got a LotR quote

trichoplax

7:35 PM

One of these:

xkcd.com/1503/#

Alex A.

@PhiNotPi Nice. Can you randomize the order of the people in the list? As soon as you see Martin you know it's going to land on Geobits.

Calvin's Hobbies

So just an image or link...

trichoplax

Certain sites onebox, most don't

Alex A.

Not just an image or link: An image or link that takes up the whole chat window.

trichoplax

It works for tiny images too

PhiNotPi

7:38 PM

Here is the code that appends the entire list several times. How do I randomize it?

var li = $('ul li'),
    spinBtn = $('#spin');

for (var i = 0; i < 2; i++) {
    li.clone().appendTo('ul');
}

While also making sure Geobits is always the first on the list?

Alex A.

Math.random... (that's all I got)

Generate a random number for each person in the list, sort by the random number.

Calvin's Hobbies

@PhiNotPi This can shuffle

It's what I used in RvB to shuffle moves

NinjaBearMonkey

The best way is to have an array of user IDs, shuffle those, and use the SE API to get all the info dynamically.

Alex A.

Calvin's Hobbies

Well cgse.tk exists but doesn't work

Mini challenge: What's the shortest url you can make (via shortener or w/e) that redirects to http://codegolf.stackexchange.com

@PhiNotPi What was that challenge of your that was about matching as many of the 100 random numbers as possible. (I think it was yours)

Alex A.

@PhiNotPi Did you get edc?

Or maybe you're doing the API way

Calvin's Hobbies

And I remember someone (Martin?) had a greedy approach that got 50 maybe (n Cjam possibly?)

PhiNotPi

@Calvin'sHobbies Definitely not me.

I'm trying the API way, but I don't know what I'm doing.

Liar's Dice is a fairly simple dice game. I've seen a few different variations of the rules, but here is the version I'm most familiar with: Each player starts with 5d6 Except when tallying the dice at the end of a round, each player may see their own dice, but not those of any opponent At the ...

@PhiNotPi Use get with jQuery and handle the data in the callback, like this

PhiNotPi

Seems nifty.

@MartinBüttner No. I'm sure this was a real and decently voted question. I might have the people all wrong though

PhiNotPi

slowly working on it...

@Calvin'sHobbies I'm having problems with getting the animation to scroll.

Calvin's Hobbies

Can I see the code?

PhiNotPi

It was li.first().animate( but obviously that's not going to work now.

@Calvin'sHobbies ^

Calvin's Hobbies

9:01 PM

You should add the users to the ul when the page loads, not on every spin(). Something like:

$(function() { //runs when interface is fully loaded
    $.get('https://api.stackexchange.com/2.2/users/' + encodeURIComponent(ids.join(';')) + '?pagesize=100&order=desc&sort=reputation&site=codegolf&filter=!qGS3sF0JLgspZPzdn__u', function (data) {
        var ul = $('ul')
        data.items.forEach(function(user) {
           ul.append('<li><img src="' + user.profile_image + '" alt="" />It\'s ' + user.display_name + '\'s fault!</li>')
         })
    })
})

(I'm trying that here: jsfiddle.net/CalvinsHobbies/9sm9qfz5/#base)

PhiNotPi

Well, the problem that I was running into (when I didn't use API) was that the random shuffle would be the same every spin.

Calvin's Hobbies

I guess you'd need to clear the ul and add back in the reshuffled users before every spin

PhiNotPi

Any luck getting it to animate?

Calvin's Hobbies

Yes

Not sure why it ends up empty

PhiNotPi

Because the spinning goes beyond the length of the list.

Calvin's Hobbies

9:24 PM

I think that shuffle function is wrong :O jsfiddle.net/CalvinsHobbies/9sm9qfz5/3 kinda works but the first person is never shuffled

PhiNotPi

That is intentional, so that Geobits would always be in the same spot.

Calvin's Hobbies

Oh :P

I'm good at making short code for more or less trivial problems.

The fact that CJam is the language I'm most fluent in shows how much of a coder I am...

randomra

anyway, I'm glad you enjoyed it (or maybe you still do)

Dennis

@randomra I'm still thinking about it, but I've more or less hit a wall.

I'm trying to find a case where my code gives a non-optimal result.

But I don't know how since this is the only approach I can think of...

Added a verifier to the boggle compression challenge.

trichoplax

10:42 PM

I can imagine the boggle compression challenge receiving incremental improvements on answers for a long time. I can't think of a good approach but I'm intrigued to see what will arrive

Martin Büttner

I guess first it needs any answer ;)

(I thought the same about Counting Diamond Tilings, but no luck so far)

trichoplax

Well your examples show it's trivially easy to find a grid that works, it just won't be very competitive...

Whereas for Counting Diamond Tilings it needs to be a fully working solution - I expect you'll get answers on Boggle Compression first

Martin Büttner

likely

although a constructive solution for diamond tilings is probably not too hard if it's based on young diagrams

and once you've got that you can start omitting diagrams which you know will only yield duplicates anyway

or maybe, looking at the full list of diagrams for larger N will give more insight into the problem for a new approach

maybe it's even easier if it's based on aditsu's and Matty's approach to the random diamond tilings challenge

trichoplax

I've added a basic JavaScript (Stack Snippet) solution for my Manhattan Exclusion sandbox post and it is horribly slow. I'm wondering whether to optimise it before using it as a time limit for the contest. It's golf so I don't want super fast answers, but I want them to finish in a "reasonable time" for small inputs

@MartinBüttner Are you hoping there might be a formula for the diamond tilings one? Or have you ruled that out?

Martin Büttner

There might be. But it's definitely beyond my number theory/group theory/combinatorics fu to be able to tell.

trichoplax

10:56 PM

foo seems appropriate... :)

Martin Büttner

foo? I thought it's a word play on kung fu or something like that.

trichoplax

But since it's found its way into a programming environment the typo seemed apt

Martin Büttner

oh right

trichoplax

If I optimise my example solution and then say answers must be at least as fast for, say, 12 by 10 with radius 5, is that going to put people off who would rather golf a slow solution?

I don't have the golfing mindset and I'm guessing one way or the other would appeal to some but not others.

By optimise I mean use an approach which is slightly less brute force
