You need to have matplotlib already installed to do any graphing.

Yeah, I have it.

Although I might not have it for Python 3.. lemme see

@El'endiaStarman Which day had the most one box messages?

parseConvos is the main function you want to use, and it returns a dictionary with three elements. The most relevant one is the one associated with 'messages', which is a dictionary where message ids are the keys and the values are yet another dictionary, with three attributes: content, user id (uid), and user name (name).

@Poke That's pretty dang cool.

6:05 PM

@zyabin101 Can't tell you that yet - I haven't yet created a database with most or all of the chat transcript.

I can get data and calculate statistics for specific days.

@Poke the hardest part with Knuth-Pratt algorithm is when the character appears multiple times in the searching string

for example, if my search string was "aaaaaaa", and I found an "a", I'd be testing 7 different possible ending points

Who here likes an idea of a time zone census of PPCG users?

I'd be okay with it

@NathanMerrill I'm still confused by your comment on my Sandbox post. Given that the hole is larger than the end of the line, should I just keep the hole rectangular, so that line gets extended? Or should the hole have an indent in it? I suppose I could also adjust the hole definition so that it's allowed at the very edges of the text and that would eliminate the issue.

Seems like a Wikipedia search for all currently used timezones and a strawpoll would do the trick

6:14 PM

@DrGreenEggsandIronMan Answered your question.

@LeakyNun change what?

@quartata Full breakdown of oneboxes on July 27, 2016: 39 total, 25 posts (Meta/Main), 9 images, 4 YouTube links, 1 tweet.

@quartata Well, I tried to install the 3.4 version with 3.5 and the installer yelled at me. I haven't found the GitHub yet

Palindrome-inize a number Inspired by this code-review question. A palindrome is a number that reads the same backwards. 12321 is a palindrome but 81 isn't. Given an integer, while it isn't a palindrome, reverse it and add the two numbers together. 9 : 9 10 : 11 11 : 11 12 : 33 47 : 121 48 : ...

Ack. I completely forgot to check Christoph Gohlke's page. He has a 3.5 version too

@Sherlock9 That guy is amazing.

Time Zone Census of PPCG Users

Isn't he just, though? :D

6:20 PM

Ping me here to add yours.

I check his page for Python libraries and Simon Tatham's page for neat little puzzles

@zyabin101 UTC+7

$hexafraction$

@zyabin101: How does daylight savings time work for your census?

@zyabin101 @zyabin101 Central European Time Zone

@mınxomaτ UTC offset?

$hexafraction$

I'm in US Eastern Time so GMT-4 in summer, GMT-5 in winter.

6:21 PM

@zyabin101 CET is UTC+1.

@hexafraction That doesn't change your timezone.

Just the local perception of time :D

Back

$hexafraction$

I meant for conversion to a UTC+/-n value.

@muddyfish I only know it's a dupe that fast because I saw that Q on CR and thought it'd be a neat challenge as well.

@TimmyD lol Ok

@Sherlock9 @mınxomaτ Added!

6:23 PM

@hexafraction The offset to UTC is always constant. Only locally that changes. E.g. CET is always UTC+1 (but it might be +2 some time during the year in Germany).

Leaky Nun is UTC+8, I think. You may want to confirm with him though

$hexafraction$

Ah, OK. I was not aware of that. Thanks!

@LeakyNun Your time zone is UTC+8?

@zyabin101 EST, e.g.UTC-500

@hexafraction The daylight saving time in Europe has an extra time zone. So all CET becomes CEST in the Summer.

$hexafraction$

6:25 PM

Ah

> As of 2011, all member states of the European Union observe summer time; those that use CET during the winter use Central European Summer Time (CEST) (or: UTC+02:00, daylight saving time) in summer (from last Sunday of March to last Sunday of October). The exceptions to this are only to Algeria and Tunisia, which use Central European Time all year round.

@CᴏɴᴏʀO'Bʀɪᴇɴ Added!

@mınxomaτ web.de xD

@zyabin101 UTC+2

@MartinEnder It's my trash address.

6:27 PM

@El'endiaStarman care to talk about syntax?

that makes sense

@NathanMerrill Sure. What's up?

@TùxCräftîñg Added!

I'm trying to figure out the syntax for indicating traits for a class.

For example, indicating that an Int is bigger than 0

or in the range 0 to 4

halp meh

i need halp

6:29 PM

@DmitryKudriavtsev oxforddictionaries.com

@DmitryKudriavtsev Just pull up a chair and stand on it to reach the top shelf.

(Don't just ask for help, say what you need help with.)

I figured it was orthography.

do you like Int@min=0@max=4 or Int[min=0,min=4]?

@NathanMerrill Stop pinging me.

@NathanMerrill The latter by far.

@mınxomaτ Wait, you get pinged by stuff in code blocks?

6:32 PM

@El'endiaStarman what if I told you that not all traits have a value?

Int[unsigned,max=10]

@El'endiaStarman Yes. The @min

Golly is for android \o

@NathanMerrill I certainly prefer that syntax to putting @ in between traits.

@TimmyD codegolf.stackexchange.com/a/86826/32686, my answer

@mınxomaτ Hmm, I wonder if I should stop using \ for functions in Pytek and use @ instead...then I can randomly ping people all the time! :P

6:34 PM

Isn't that technically a stealth ping.

@El'endiaStarman and what about Int[unsigned,max(10)]?

@mınxomaτ No, a stealth ping is one you can't see. Actually, did the code get highlighted?

the bonus is that I can pass multiple parameters to a Trait

@NathanMerrill Less preferable, but better than infixing @s.

Business Cat

@zyabin101 North American Eastern Time here

Which I believe is UTC -6

6:35 PM

@NathanMerrill Hmm, that would be nice to have.

so, you'd like Int[range=(4,5)] over Int[range(4,5)]

I guess its not that much more complicated

@NathanMerrill Hmm. Yeah, I suppose, but marginally so.

It might help you to write more pseudocode to see what style you prefer.

I bounced back and forth when writing my pseudocode

Golly crash when i fhange the state on my phone (strange char)_(idk how to fopy)

use Collections.*
use Optional.*

fun binarySearch(target: T)
        on (Ordered<T>,Indexed<Int,T>):
        Optional<Int[min=0,max=this.size]> {
    low = 0
    high = this.size - 1
    while (low <= high){
        mid = (low + high) / 2
        comparison = this.orderer(this[mid], target)
        if (comparison < 0){
            low = mid + 1
        } elif (comparison > 0){
            high = mid -1
        } else {
            return Some(mid)
        }
    }
    return None
}

6:40 PM

@BusinessCat Added!

the other part I'm unsure about is the on statement. (Its indicating that its an extension method for any object that implements both Ordered<T> and Indexed<Int,T>)

I'm not a huge fan of where its at

Also, Business Cat, do you want to work on MtG cards?

@NathanMerrill Maybe use for instead? Oh wait, no, that probably wouldn't be a good idea...

that was actually iteration 2

iteration 1 was ExtensionClass.funcName

but I didn't like that because the function name is more important than the class name

help me please, I need an idea for something to submit.

6:43 PM

I mean, I could do for. A for loop at that location makes no sense, so it wouldn't be ambiguous

I say ditch the "this" and have the container by a regular parameter.

@NathanMerrill Yeah, I did eventually realize that.

Also your return type seems to have a bug.

@feersum like python?

so, the first parameter is self?

@NathanMerrill No not like that.

Just a free-standing function.

6:45 PM

oh, right, it could totally be a free-standing function. I definitely want extension methods, so I need a syntax to support it

What would you do for an algorithm that uses two containers?

It wouldn't naturally belong to one of them.

any sorted List<> would implement the two interfaces

@feersum what do you mean by this?

oh wait, I realized a bug in my syntax

Wait, does max 10 mean the highest is 10 or the highest is 9?

9

9

6:49 PM

Never mind then.

Ordered is a trait, not an interface.

In general ranges are [x..y)

so, it should be on (Indexed<Int,T>[ordered])

hmmm

that doesn't make sense

@TùxCräftîñg Well, that's Pytek syntax for ranges, yes.

I haven't seen it much elsewhere.

@El'endiaStarman neoscript use a variation of it x:(step=1]:y

The step is opyional

6:54 PM

@TùxCräftîñg That's so different you can't call it a "variation".

:/

bah, I need someway to collect parameters on traits

Its easy to parse

Hrb

my first thought was to do on (Indexed<Int,T>[orderedby=U]), and then use U.orderer, but that doesn't make sense because U isn't a type

@NathanMerrill Do you know C++? The things you are getting at are very much like the STL.

6:58 PM

@feersum oh, I know

and I understand the basics of templating

The C++ binary search algorithms also support searching for an object that is a different type from the list elements, which is often useful.

@fe

I'm not really familiar with C++'s advanced features.

How do you write a lambda function and assign it to a function pointer?

Also, are there map literals?

@feersum we're talking searching in an int array for a double?

@mınxomaτ what would this entail?

@NathanMerrill Yep.

7:02 PM

@CᴏɴᴏʀO'Bʀɪᴇɴ git.io/podprop

@DmitryKudriavtsev Two letters isn't enough.

OK.

@fee

B

void(*f)() = []{};

umm wat

How do you call this function?

7:03 PM

f()

*f(1,2)

**

???

You don't need to dereference it?

No.

That is very strange.

@feersum functions arr pointrr

You can only assign directly to function pointer if the lambda has no captures though.

7:04 PM

Huh wrong ping

When were lambda functions introduced?

@mınxomaτ cool, thanks. I'd love to join my internet is unpredictable & microphone sucks. Look forward to listening to it though!

Cxx11

What was introduced in C++14?

but, in comparison to C++'s type system, traits are going to be a bit different, because they can be implied, and don't need to be declared. For example, performing a test a > 0 implies that a has the Unsigned trait inside the true condition

7:06 PM

@CᴏɴᴏʀO'Bʀɪᴇɴ The internet connection is not relevant for the recording and there are hardly any really bad microphones.

@mınxomaτ Tell that to my POS microphone

@mınxomaτ "A stable enough internet connection so that while the conversation is running, you can be understood"--my internet drops randomly.

@CᴏɴᴏʀO'Bʀɪᴇɴ Join per phone then :D

oooo not a bad idea

I'll think on that

I can even set up a tollfree number.

7:08 PM

@CᴏɴᴏʀO'Bʀɪᴇɴ @mınxomaτ what are you talking about?

4 hours ago, by mınxomaτ

@Everyone: Drop me a short mail at squarecode@web.de if you'd be interested in being a part of a PCCG/Coding podcast. Also include any topics or other ideas you might have.

@DmitryKudriavtsev git.io/podprop

ok

the only thing I could talk sensibly about is language design :P

I'd really like to have that link the in the starred message, but can't edit it anymore.

@CᴏɴᴏʀO'Bʀɪᴇɴ Who said anything about sensible :D

7:09 PM

@mınxomaτ ask a mod to eleven it in

@mınxomaτ :D

@mınxomaτ (real ping :D) I prefer listening to 2 guys talk instead of 5. I find its harder to keep track of more than 2 or 3 people. I'd be totally ok if the 5 rotated though.

but, that's just a personal opinion

@CᴏɴᴏʀO'Bʀɪᴇɴ Eleen it in?

eleven*

@mınxomaτ Want me to edit this into the starred message?

@El'endiaStarman Yeah, maybe to this: "Please visit git.io/podprop if you're interested in being a port of a PPCG/coding related podcast."

@zyabin101 When @BusinessCat said North American Eastern Time, I think they meant Eastern Standard Time, which is UTC-5

7:15 PM

@mınxomaτ Done. And I fixed your typo while I was at it. :P

@DmitryKudriavtsev sorry, kind of a meme. "Mod abuse 11" is when a moderator edits a message to say something else. Abuse here is more sarcastic than anything else. To "eleven" a message is for a moderator to commit "mod abuse 11"

@El'endiaStarman You missed the http

Shoot.

I'm new to StackOverflow and have been told by my colleagues that the users of this site are "mean" and "jerks", especially to new users. Since I would like to properly integrate myself into this community, what are some good practices to correctly be a jerk on StackOverflow?

@Dennis Could you pull Grime again, please?

@CᴏɴᴏʀO'Bʀɪᴇɴ Oh, it's because my last chat activity was hours in the past.

hai

oh, that makes sense

that's quite humourous

7:19 PM

With this update, I can finally do path-finding in Grime!

@mınxomaτ I posted in the 2nd Monitor. They seemed busy though chat.stackexchange.com/transcript/message/31352169#31352169

@Sherlock9 Edited.

@Zgarb sweet, what did you change? :)

@Phrancis hallo

@MartinEnder I added context brackets, which allow you to look outside a rectangle to determine whether it matches.

7:28 PM

@Phrancis Can someone with enough SO rep post a screenshot?

^

@Zgarb interesting :) ... are you going to answer the Mario challenge to showcase it?

@MartinEnder I might do that tomorrow, it doesn't look too difficult.

ping me when you do :)

Will do!

7:29 PM

I was looking through our 2D pattern matching languages when I did Snails and Slip, but decided I couldn't be bothered to formulate this as a problem on rectangles :D

@mınxomaτ Besides Code Review, in what other parts of SE could I search for possible contributors or listeners? Programmers.SE?

Hi eveyone

Hello

7:30 PM

@MartinEnder I think the Mario challenge was actually impossible in Grime before this update.

Oh, good thing I didn't try then :D

Too bad the Mario challenge spec is still broken.

Alright, time to sleep now. I have an early wake-up tomorrow. G'night!

night! good luck on whatever it is tomorrow!

@Sherlock9 I think we should start with participants from this site first. Give it a day or two so we can hit all time zones.

7:36 PM

Fair enough. I would like to make that summarized message though. Just so we get the basics across quickly

I'm just checking in cuz I'm in india, first time I've got a computer in forever, (and I'm on dial up atm) anything exciting been happening round here lately?

If that's okay with you

@Maltysen we got our design, it looks exactly identical to the beta design except if you stare at it for ten minutes the title font changes

It's a bug apparently

@zyabin101 @Maltysen is in India. I believe that's UTC+5.30

@Maltysen well, we each got a free million dollars, but only while you were gone

7:37 PM

@Sherlock9 Sure, still link it though.

@mınxomaτ got my email?

@Sherlock9 I think he's implying he's travelling

@Sherlock9 I'm not sure that's where they live. Could just be a visit.

@muddyfish Yeah. If you have a github acc, can you comment or star the Gist so I can keep track?

@mınxomaτ done

7:39 PM

yay

@quartata wow ours must be the first se design to use webcams and facial recognition :P

Right. @zyabin101 Never mind that last post

Ah double check with Maltysen

@Maltysen Your time zone is UTC+5:30?

@quartata I am traveling, but gonna be here for a while

7:40 PM

@quartata ahh, did they not tell us when they removed the beta sticker?

@Maltysen I'm amazed that you're keeping the se chat websocket alive over dialup

That sounds fun

Would ppcg people be talking in it?

@Sherlock9 I'd be totally up for that if that didn't mean I had to talk and expose everyone to my bad mic quality and noisy computer fans

@quartata Well, if you can get a decent place to record from (your phone, perhaps), let minxomat know

@Doorknob where did you get this stunningly gorgeous "skin" for Stack Overflow?

@Phrancis I wrote it! It's fairly comprehensive; it covers all SE sites, chat (i.imgur.com/AAMzzYV.png), and some other stuff. I'm working on polishing it up and then I'll probably post it on meta or something, but for now it's in my dotfiles repo

@CᴏɴᴏʀO'Bʀɪᴇɴ thanks :)

@Doorknob Post it for a code review at some point :D

Oh noes, it's all CSS D:

How do you make it work? That needs a README pretty badly:)

@Phrancis Oh, there's a tiny JS userscript that you have to use as well (so that site-specific themes are removed)

@Phrancis Psh, I'm not documenting my own dotfiles. :P It'll all make much more sense once it's done

There's no better way to do it though

It did strip all theming, so that's that

@Sherlock9 Thanks!

@muddyfish Thanks!

Well, I have a list of about 30 webcomics that I can recommend now or narrow down first. Comics that I check regularly

Would you prefer the whole list or should I condense it first, @flawr?

@Sherlock9 Well my problem is that when I open my list, it already touches almost the bottom of my screen =/

@quartata ikr

So I'll probably need a bigger screen.

Hm, that's a problem

8:17 PM

Didn't we already exchange our lists at some point?

Let me post it for anyone interested, and we'll see if there's overlap

Comics that I check regularly: Gunnerkrigg Court, Girl Genius, Dumbing of Age, Schlock Mercenary, Archipelago, PVP, Table Titans, Paranatural, Octopus Pie, Questionable Content, Woodson, Widdershins, El Goonish Shive, It Never Rains, Skin Deep, Something Positive, Star Power, Freefall, Grrl Power, Kiwi Blitz, Leftover Soup, Between Failures, Blood Spattered Socks, Monster Pulse, Monsterkind, xkcd, Cucumber Quest, Pin Porter Girl Detective, How to Be a Werewolf, and Panthera

A few months ago or so?

@flawr I thought so, but I don't see it in the transcript

@Sherlock9 You should add SMBC to that list :D

Queen of Wands comic is best comic.

8:17 PM

Let me look again

@Doorknob I should, but it has been a while since I could binge read, and that list is only the comics that I have read most or all of the archives and read regularly

SMBC is at, what, 3000 comics now?

@Sherlock9 do you have some sort of aggregator?

I check them one at a time like a pleb :D

so you have a huge list of links oO

@Sherlock9 Want mine too?

@flawr Well, it's not in the transcript. Did we share lists in Discord chat perhaps?
