Oh. You have gotten to plotting stuff, didnt you?

Christopher Peart

yeah the problem is scaling

If I add .1 to I instead of 1

I can't figure out how to scale it right

ideas?

Matthew Roh

Dynamic scaling?

What color do you see your pings highlighted in? When people ping you

strawpoll

DJMcMayhem

Dang, strawpoll updated

Riker

no

different wobsite

strawpoll.me vs strawpoll.com

for whatever reason the first one didn't pop up in my search bar so I accidentally used .com instead

didn't notice until after that it wasn't just an update, different wobsite

DJMcMayhem

01:03

Apparently no one is answering your poll

Riker

I noticed

Matthew Roh

I am

ATaco

Someone ping me.

DJMcMayhem

@ATaco OK

Q: An abundance of integers!

An Abundant number is any number where the sum of its divisors is greater than twice the original number. For example, the divisors of 12 are: 1, 2, 3, 4, 6, 12 And summing these results in 28. Since 28 is larger than (12 * 2), 12 is abundant. Note that this does not include "Perfect numbers",...

ATaco

@MatthewRoh proper way or the taco way?

Matthew Roh

Taco way

ATaco

We are at an inpass.

github.com/TehFlaminTaco/TacoBot/blob/master/TacoBot.js

That's TacoBot, he's literally a script ran in the Firefox Console.

Half of him is written in JS, the other half, Lua.

Matthew Roh

Wait

ATaco

01:24

@Riker Add green to your strawpoll please.

Matthew Roh

How come I forget there is a nodejs library for chat

ATaco

Pfft, Who needs node-JS when you have a Firefox console?

Me, probably.

Matthew Roh

Pfft

You can run it 24/7 on heroku

By using nodejs

And cancer

ATaco

TacoBot was written purely to see if I could.

Apparently, I could.

And I really need to learn how to name things.

Matthew Roh

Name it burrito

ATaco

01:36

Botrrito?

Matthew Roh

Uhh

Maybe ATaco + Bot = BoTaco

DJMcMayhem

Or "ABotO"

ATaco

AtaBot

ATA-Bot

ATaco's Awesome bot.

Matthew Roh

@Dennis o_O which comment?

Christopher Peart

Actually DJ ping me

Or anyone rly

Destructible Watermelon

@ChristopherPeart no

Christopher Peart

@DestructibleWatermelon so meen

Guys the graph bwoke

Destructible Watermelon

for my 2d lang, I need some ideas

It is going to be on a circle, where the IP circles around, and can go inward and outward

What kind of operators should I have?

ATaco

Only xor and %.

wat

wait was @noɥʇʎԀʎzɐɹƆ suspended?

Destructible Watermelon

02:22

@ATaco why

also I was thinking the language might be called (o)

because it looks like a disc

and () doesn't really work

Dennis

It's a shame you can't do range(n). That pesky modulus by zero — DJMcMayhem 42 mins ago

02:27

@wat maybe

yeah that looks nice

Dennis

@ChristopherPeart The colors in your pie chart appear to be backwards. Also, why would something trade soothing red for puke green? o_O

Destructible Watermelon

also I was gonna use non-euclidean space

Dennis

@ChristopherPeart For whatever reason, you can ping yourself. That's best done in the sandbox room though.

Destructible Watermelon

instead of C/D = pi, C/(D**2) = constant

that'd be fun

Dennis

@Dennis Unless you need to reply to yourself for context.

Destructible Watermelon

02:29

just to confuse everyone

@Dennis it tends to make you look like you are talking to yourself though

like a crazy person

Dennis

My father used to say "It's the only way to have an intelligent conversation".

@DestructibleWatermelon The best part about Lobachevskian geometry is the look on people's faces when you tell them the sum of the inner angles of a triangle isn't constant, but always strictly less than 180 degrees.

Maltysen

@DestructibleWatermelon Lobachevskian?

Matthew Roh

@Maltysen this.

Maltysen

oh, hyperbolic geometry

was lobachev(ski?) the guy who invented it?

Dennis

02:45

Did you mean to ping me?

Maltysen

._.

yes

Dennis

I'm destructible, but not a watermelon.

Hyperbolic and elliptic geometry are oftentimes referred to by their respwctive pioneers' names: Lobachevski and Riemann.

That and the theorems regarding the sums of triangles' inner angles are pretty much the only thing I remember from my non-Euclidean geometry course.

hmm, I have a feeling that a really good answer to the "minimal character set" could take weeks of work in many languages

for example, is let = Turing-complete in Haskell? It's close, but some experimentation has failed to reveal whether parentheses are necessary

most of the subsets I'm looking at are basically small esolangs of their own

what about answers which depend on unproven mathematical hypotheses?

ATaco

the mov assembly command is turing complete.

ais523

on some processors, yes

ATaco

As is xor.

ais523

but it needs a lot more than three characters as it relies on weird addressing modes

printf is also Turing complete (if you use pointers that point at the format string, allowing it to overwrite its internal state as it runs)

ATaco

Many strange things are strangely TC.

Pavel

03:31

FerNANDo, anyone?

BTW, is the C preprocessor TC? I've wondered.

ATaco

Yep.

But I'm not sure why you would use it.

github.com/orangeduck/CPP_COMPLETE

This is BF written in C's pre-processor.

@ATaco Reduce the code size of e.g. compile-time LUTs. You can use order/choas to achieve sane metaprogramming in cpp: chaos-pp.cvs.sourceforge.net/viewvc/chaos-pp/order-pp/example/…

P99 is based on that: gustedt.wordpress.com/2012/02/21/…

ais523

03:51

@EriktheOutgolfer: Jelly is fairly easy to prove Turing complete if you have an unrestricted character set; the easiest proof is to implement the while language using ¿ for while loops (obviously), a list to store the variables, ¦ together with integer literals and + to manipulate the variables, and ị together with integer literals to write the loop tests

this probably isn't the way to go to minimize the character set though

@HelkaHomba is that intended as a puzzle, or is it something you're stuck on?

It's helka, of course it's a puzzle :P

I'd rather not

Downgoat

@wat my god

I am flagging as obscene :P

wat

@Downgoat yeah it's pretty neat

Downgoat

Idea: iOS app for SE chat

wat

@Downgoat I am already making a desktop app, I cannot figure out the api

Downgoat

> cannto ffigure pit that api

i think you jeoufdj a word :P

wat

05:08

I was typing with my eyes closed\

Downgoat

@wat for auth or chat WS?

wat

both

I don't even think there IS a ruby api

Downgoat

@wat auth is easy enough I can use my current OAuth solution that I use in GH

hard part is cracking WS API but I think @Quill has done that

wat

Who is @Quill

Downgoat

O_O

he helped make parts of cheddar

he used to be an active here but he dissapeared for a while, I guess school

I found really nice websocket API for swift too

wat

05:12

> an active

Downgoat

?

wat

Why not just use phonegap?

Downgoat

is this joke

wat

no

It is electron for phones basically

Downgoat

I thought you hated electron

Well if you're using HTML/CSS on app you might as well do a website

wat

05:14

well, I mean that it might make deveopment of the SE chat app easier because then you can just use the websocket API that SE provides

Downgoat

we can already use with Starscream?

Safari actually has a specific tab to monitor sockets

wat

no need to swift. also afaik you love js

Downgoat

@wat yes for website

you'll end up with a facebook like-app

wat

also apparently someone at my school plugged a usb killer into my computer and that is why i can't use usb devices

i hate my life

Downgoat

you won't be able to use cool native API (or any API) and your app will be slow, look like crap, and be buggy as crap

@wat D: that sucks

05:17

parents dont want to take me to the surplus sale where I got it to get a new one because "I broke it as an excuse to get a new one"

No idea who it was

Downgoat

@wat same happened with my iPad :/

Matthew Roh

I just soldered my first pcb

I am very proud of myself

Downgoat

:D cool, what does it do?

Matthew Roh

05:21

I just soldered a header on an RFID module XD

Stack Exchange App Test

Hello

I actually just soldered a thing to a pcb

Matthew Roh

But I learnt a nice skill of soldering a header not perpendicular but 15 degrees

Stack Exchange App Test

was half of a usb cable soldered to power headers on an orange pi zero

Matthew Roh

lmao

Stack Exchange App Test

@MatthewRoh why?

Matthew Roh

05:23

I had nothing to hold the headers

Stack Exchange App Test

oic it was accidental

Matthew Roh

when I realised it was tilted, I couldnt fix

Stack Exchange App Test

How does one desolder a header

Matthew Roh

My skills are getting better tho

Helka Homba

@Downgoat Correct!

Stack Exchange App Test

05:23

do you have a desoldering pump?

Matthew Roh

nah

Stack Exchange App Test

oh

Matthew Roh

no desoldering stuff yet

Downgoat

@HelkaHomba :D

Matthew Roh

but I'm planning on buying a wick

wat

05:24

@Downgoat I have the file "se-chatty.rb" from somewhere but it goves me errir

gives me error

Downgoat

@wat wait so you are familiar with SE's WS?

can you tell me what weird base-64 is in "wss://chat.sockets.stackexchange.com/events/1/ea95d48070594fa4b228a9c73d7a5d18?‌l=68583996"

wat

@Downgoat not really

also that looks like hex

Downgoat

shit same thing

Helka Homba

@Downgoat How did you figure it out?

Downgoat

@HelkaHomba well I noticed it looks familiar like the vertical series of the powers of 5

can someone come into a sandbox and post some messages (and edit some)?:

@DJMcMayhem read each column downwards, you'll notice that they recur

Helka Homba

starting at the right all 5's, then 2's, then 161616..

Downgoat

that is really interesting series though

you should make challenge out of it

Helka Homba

I might

I thought it was 5, 12, not 5, 2 <_<

I get it now, that's cool

Random Question: do you use iphone or android

DJMcMayhem

Android (Google pixel)

Downgoat

@StackExchangeAppTest for OAuth you need an oauth server, just spin one up and give ChatExchange that token

@StackExchangeAppTest D: then iOS app will not work

No idea how to authenticate with OAuth so I am using this account. When I figure it out I will instantly switch to main account

heyyy you just removed legitimate messages

DJMcMayhem

If they're legitimate messages, why not use your real account?

Downgoat

@StackExchangeAppTest ... or just open up your browser

please use sandbox for testing your bot

Stack Exchange App Test

05:44

Because I am testing the Stack Exchange App

DJMcMayhem

@KritixiLithos It's awesome, but I'm not sure how much of an improvement it is over recent OS's since my last phone was on 4

Stack Exchange App Test

Not trying to create a bot. I am writing a desktop app for SE chat

DJMcMayhem

@StackExchangeAppTest The keyword here being testing

Downgoat

I thought KitKat was newest version ._.

@StackExchangeAppTest you realize you can test in sandbox

Stack Exchange App Test

ugh whatever I'll try another way

wat

05:45

I just stopped the client

DJMcMayhem

Thankyou

@KritixiLithos Is google assistant the "OK Google, please XYZ..."? Like the google equivalent of Siri?

Kritixi Lithos

Yes, but Google Assistant > Siri

DJMcMayhem

If that's what you mean, I love it. (I'm just not entirely sure about the terminology)

Kritixi Lithos

That's what they called it in the October 4 madebygoogle event

DJMcMayhem

There's a lot of things I really like about it that stand out more because my last phone was so old.

Downgoat

05:47

@KritixiLithos ಠ_ಠ Google Assistant does not give you funny answer when you say "will you marry me" like Siri

DJMcMayhem

For example, fingerprint scanner, android >4, Google assistant, a decent processor

Kritixi Lithos

@Downgoat But Google Assistant makes great puns

Downgoat

you should actually be able to do swift for android because android is based on linux and swift does linux

> The Swift stdlib can be compiled for Android armv7 targets, which makes it possible to execute Swift code on a mobile device running Android

:O

Kritixi Lithos

@DJMcMayhem You mean android version 4 (kitkat/jellybean)? That's old

DJMcMayhem

Yeah, Samsung likes keeping their users in the stone ages

Downgoat

05:48

@DJMcMayhem stones usually don't spontaneously combust

DJMcMayhem

Battery's also quite a bit better. My last phone would never last the full day until I bought a big ugly third party batter that lasted like 3 days. My current battery very rarely runs out in the evening

Kritixi Lithos

@Downgoat You can also do C/C++ on Android (using NDK)

DJMcMayhem

For example, I haven't charged my phone since this morning, and it's at 37% right now (10:50 PM here)

Kritixi Lithos

But also the Pixel charges quickly

DJMcMayhem

Oh yeah, the fast charge? It's very nice

Overall, I'm most impressed with the attention to detail, and the minor UI things

Downgoat

Goddammit, I just spent like two months getting the hang of iOS dev

now everyone is Android :(

Mistah Figgins

@Downgoat Sure. How?

Downgoat

05:53

do you have xcode?

Mistah Figgins

Dunno what that is... so probably no

ATaco

RProgN 2 is now actually Turing Complete.

Yay.

Downgoat

@MistahFiggins oh, do you have a mac?

ATaco

And the compiler isn't terrible, too.

It's basically a miracle.

Downgoat

what language did you code RProgN in?

06:00

How to login to stack exchange with google openid programmatically?

ATaco

RProgN, The First Verson is Lua.

RProgN 2 is Java.

ATaco

Basically I only write languages in languages that make people cry.

mınxomaτ

I like Lua.

ATaco

Darn

Downgoat

06:01

@wat I think best way is to just use SE OAuth

ATaco

RProgN 2 actually features a sort of Compiler, instead of just trying to interpret chunks of string.

wat

But hten how would people who only have googel oauth on their accounts (like me) log in?

Downgoat

@wat it would likely bring you to the SE login page where it would just give you the client ID regardless of the user's login option

wat

@Downgoat ...what

Where do I POST the data?

ATaco

Someone write a BF interpreter in Magic the Gathering.

Downgoat

06:04

you get a client ID and you post that to SE's OAuth endpoint to get your auth key

wat

@Downgoat where do I cliient ID?

Downgoat

you get a client ID from the oauth auth page

the user interacts with that page

wat

I don't have a webview or anything

Downgoat

you are making command line app right?

because SE Oauth uses google OAuth so if you don't want to add GUI you have to do double OAuth

kinda like windows' UAC

wat

no, I am making a GTK app

Mistah Figgins

@Downgoat nope.

Downgoat

@MistahFiggins are you OK if I ping you later this week asking if you'd like to be beta tester of GH app?

@Downgoat can you please make me beta tester?

Downgoat

you have full access to repo already ._.

you can just clone and plugin phone

actually lemme push latest version. I added cool things such as finishing user profile screen and sorting

Model-View system is also really cool

wat

Remember, usb killer

cannot plugin phone

Downgoat

oh no D:

so is entire computer broken or just USB port

wat

06:37

i might just get a usb express card

just usb ports

amazon.com//dp/B0046XUMDW

That would even give me usb3 (laptop only has usb2 rn)

Downgoat

ok well first I have to buy $100 apple developer license, and then I can do OTA

mınxomaτ

@wat Can confirm works great. Did the same thing to a 2009 laptop.

that would have pcmcia, no?

mınxomaτ

Yeah.

wat

06:39

different things. this is just pcie in a card

mınxomaτ

Uh no.

PCMCIA is Express Card. I used this one: amazon.de/CSL-PCMCIA-Express-Windows-Notebook/dp/B008BHN6MI

Downgoat

btw @wat your chat profile says you're a guy but your profile picture shows you as giant duck, which one do I believe

mınxomaτ

Which is the same thing with a different label.

wat

Um, no

ExpressCard

ExpressCard, initially called NEWCARD, is an interface to connect peripheral devices to a computer, usually a laptop computer. The ExpressCard technical standard specifies the design of slots built into the computer and of expansion cards to insert in the slots. The cards contain electronic circuits and sometimes connectors for external devices. The ExpressCard standard replaces the PC Card (also known as PCMCIA) standards. ExpressCards can connect a variety of devices to a computer including mobile broadband modems (sometimes called connect cards), IEEE 1394 (FireWire) connectors, USB connectors...

PC Card

In computing, PC Card is a configuration for computer parallel communication peripheral interface, designed for laptop computers. Originally introduced as PCMCIA, the PC Card standard as well as its successors like CardBus were defined and developed by the Personal Computer Memory Card International Association (PCMCIA). It was originally designed as a standard for memory-expansion cards for computer storage. The existence of a usable general standard for notebook peripherals led to many kinds of devices being made available based on its configurability, including network cards, modems, and hard...

@mınxomaτ was talking about pcmcia vs express card

mınxomaτ

ExpressCard

> Year created 2003

Yep, then it was ExpressCard. Still, the product page says PCMCIA.

wat

ok

afaik pc card uses ISA and PCI bus and then ExpressCard uses PCIe bus and USB

Oh yeah! @mınxomaτ

> ExpressCard is a later specification from the PCMCIA, intended as a replacement for PC Card, built around the PCI Express and USB 2.0 standards. The PC Card standard is closed to further development and PCMCIA strongly encourages future product designs to utilize the ExpressCard interface.

mınxomaτ

Huh

> This acronym was difficult to say and remember, and was sometimes jokingly referred to as "People Can't Memorize Computer Industry Acronyms"

Pavel

06:51

To be fair, that's mostly the computer industry's fault. Even the companies themselves are named things like IBM and AT&T.
