That would net you somewhere between 1-3k I think

bkul

My new language is coming along nicely! I'm able to start implementing it in itself.

Fatalize

@bkul Link?

bkul

@Fatalize Sure, one moment.

Fatalize

4:17 PM

@bkul zzzZZZ

bkul

sorry sorry

@Fatalize github.com/nazek42/fith

Fatalize

thanks

bkul

There's no documentation at the moment.

4:39 PM

My blog has one article, but 500 readers per month o.O

Cᴏɴᴏʀ O'Bʀɪᴇɴ

What is it about?

mınxomaτ

The article is about WSL

Has about ~45 readers per day since one day after publishing.

Cᴏɴᴏʀ O'Bʀɪᴇɴ

wait it's "oo-bun-too" not "you-bun-to"?

and did you make this graphic in powerpoint? o_o

or was that microsoft

mınxomaτ

MS

Cᴏɴᴏʀ O'Bʀɪᴇɴ

ಠ_ಠ they still have the spell checker red underline

mınxomaτ

4:45 PM

Yeah, that amused me, too.

Upgoat

@Quill Yeah, I'll take a look at your unit testing because I have no idea on how to chai :|

@Quill yeah

Cᴏɴᴏʀ O'Bʀɪᴇɴ

> More posts on WSL will come.

mınxomaτ

Didn't say when :P

Cᴏɴᴏʀ O'Bʀɪᴇɴ

"This seems good, but it will be bad. Eventually."

mınxomaτ

Actually Docker is now natively supported in Windows Hyper-V containers. So that's probably next.

Cᴏɴᴏʀ O'Bʀɪᴇɴ

4:51 PM

What is Docker?

Zgarb

@LeakyNun Not even that, just shifting each symbol one step to the left. Like abaabab... -> baabab...

Cᴏɴᴏʀ O'Bʀɪᴇɴ

@Quill ಠ_ಠ you forgot this

Upgoat

@Quill and this one which is just good in general

mınxomaτ

@CᴏɴᴏʀO'Bʀɪᴇɴ You really don't now?

docker.com

Cᴏɴᴏʀ O'Bʀɪᴇɴ

@mınxomaτ No, I don't.

huh

El'endia Starman

4:54 PM

I did not know about Docker either until just now.

Upgoat

what should be the syntax for constructing a class?

mınxomaτ

Better link: github.com/docker/docker

Upgoat

I don't like new foo() because that seems hard to parse

Zgarb

@Upgoat Do you mean defining a class, or constructing an instance of the class?

Fatalize

I don't see what would be simpler

Upgoat

4:57 PM

@Zgarb constructing an instance of a class

Zgarb

Just drop the new?

Alex A.

@TimmyD Cool. I didn't know how useful it would be, I just thought it was neat.

Upgoat

@Zgarb but then that would be function syntax

Fatalize

@Upgoat Constructors are function

Upgoat

that's true :/ but I don't like that syntax.

idk, I'll think of something

Fatalize

5:04 PM

@Upgoat variable <- Foo()

Zgarb

If you want to distinguish between functions and constructors, require one to start with an uppercase char and the other with lowercase.

Upgoat

no, that's too cheesy

Ba Dum Tss!

►

Fatalize

@Upgoat Foo(params) foo;

same as declaring a variable but with params after the class name

(or no params just the parenthesis if there are none)

no parentheses => just a declaration

Upgoat

llooks too much like C

Fatalize

wat

Zgarb

5:07 PM

@Upgoat foo((params)) :P

Upgoat

@Zgarb but (params) is a valid expression unfortunetly

Fatalize

C doesn't even have classes

Upgoat

yeah, but you see this pretty often in C where the var is at the end: typedef struct {} goat;

Zgarb

@Upgoat Oh right, and it probably can be semantically different from params

Fatalize

Foo foo = Foo{...}

Zgarb

5:09 PM

How about foo:(params) or :foo(params) or foo'(params)

Fatalize

Foo foo = ~Foo()

like C++ destructors, assuming you can't call destructors

Upgoat

@Zgarb Yeah, I was considering those but : is range operator

Cᴏɴᴏʀ O'Bʀɪᴇɴ

btw, for the switch thing, a possible snag would be 1, 2:3 : 4

Upgoat

I think I might just do new and have it do a check if it's a class and all

Zgarb

Well, use some other non-alphanum char that doesn't have another meaning yet. Assuming you have one, of course.

Upgoat

5:12 PM

@CᴏɴᴏʀO'Bʀɪᴇɴ oh shit :| this : operator is causing lots of problems

@Zgarb maybe unary *

Cᴏɴᴏʀ O'Bʀɪᴇɴ

@Upgoat just re-assign it to something else :P

Upgoat

@CᴏɴᴏʀO'Bʀɪᴇɴ to what though? ._.

Fatalize

use @ or _, it's useless

Upgoat

@Fatalize _ is for properties

@Fatalize Probably gonna use @ for some special literals

Cᴏɴᴏʀ O'Bʀɪᴇɴ

maybe x $ y could be range

Upgoat

5:14 PM

ew no :P

Cᴏɴᴏʀ O'Bʀɪᴇɴ

Why not?

Fatalize

%? #? ~?

Upgoat

idk, it's just really odd. Like I've never seen it before

Zgarb

@Upgoat Do classes always have exactly one constructor?

Upgoat

I could try .../.. but that would require spaces around the numbers, so 1 .. 5 which some people may not like

@Zgarb yeah

at least they're resolved to one

zʏᴀʙiɴ101

5:15 PM

The poll has ended a few hours ago!

No result.

Upgoat

;_; cheddar without semicolons doesn't work

zʏᴀʙiɴ101

As such, I have to ask @Upgoat in the zyabinVI beta room for help on creating a new project.

(Upgoat, you will come there, won't you?)

Fatalize

project idea: finish Cheddar

zʏᴀʙiɴ101

@Fatalize This is not a zyabinVI project idea.

Upgoat

@zʏᴀʙiɴ101 I have to do some work finishing cheddar

zʏᴀʙiɴ101

5:17 PM

@Upgoat Okay, so I should expect you in the room in a few days, okay?

Upgoat

I'll try :)

CheddarPropertyToken {
  Code: 'foo::bar',
  Index: 3,
  _Tokens:
   [ CheddarVariableToken { Code: 'foo::bar', Index: 3, _Tokens: [Object] },
     '-1': 'undefined::' ],
  Type: Symbol(Property) }

I borked something bad :|

Cᴏɴᴏʀ O'Bʀɪᴇɴ

I get you. Parsing isn't fun

Fatalize

:: ????

and then you complain about my thing looking like C

Upgoat

that's casting operator

String::123 -> "123"

Fatalize

wat

Upgoat

5:19 PM

@Fatalize s/C/C++/

Zgarb

@CᴏɴᴏʀO'Bʀɪᴇɴ Unless you use parsec!

Upgoat

@Fatalize ._. type::variable

Fatalize

@Upgoat I know it's C++, but you complain about my thing looking like C

zʏᴀʙiɴ101

@Upgoat here's a report on the Cheddar REPL:

`print` is transparent: prints *and* returns the string.

Comments return `Symbol(KEY_NOT_FOUND)`.

String formatting does not work.

`1__2345` crashes the interpreter.

```

            throw err;

Fatalize

@Upgoat yeah I got it, but it looks... dubious

Upgoat

5:20 PM

@zʏᴀʙiɴ101 oh god

`[1, 2, 3, 4]` prints these tokens:

```
[ CheddarExpressionToken { Code: '[1, 2, 3, 4]', Index: 2, _Tokens: [ [Object] ] },
  CheddarExpressionToken { Code: '[1, 2, 3, 4]', Index: 5, _Tokens: [ [Object] ] },

  CheddarExpressionToken { Code: '[1, 2, 3, 4]', Index: 11, _Tokens: [ [Object] ] } ]

Cᴏɴᴏʀ O'Bʀɪᴇɴ

@Zgarb I don't even know what I just read ... o_o

Upgoat

i dunno what's wrong here, @zʏᴀʙiɴ101 post these on GH so I can plan on fixing them :3?

Cᴏɴᴏʀ O'Bʀɪᴇɴ

keep the code to the github issues page and link us

zʏᴀʙiɴ101

Here's the public C9 workspace where I test Cheddar: ide.c9.io/schas002/cheddar

Fatalize

"public" "Please sign in"

Cᴏɴᴏʀ O'Bʀɪᴇɴ

5:23 PM

as opposed to private, where you can't access it.

@Upgoat you deleted your blog??

Upgoat

@CᴏɴᴏʀO'Bʀɪᴇɴ no I moved it to blog.vihan.org

Cᴏɴᴏʀ O'Bʀɪᴇɴ

oh, okay

LegionMammal978

Question: Why does 10^(log(2)*n)=2^n?

It looks like it should be 2*10^n

(log is base 10 in this instance)

quartata

x^(y*z) != x^y * x^z

Zgarb

Because it's the same as (10^log(2))^n, and 10^log(a) == a when the logarithm is in base 10.

LegionMammal978

5:33 PM

Oh, facepalm

Question 2: log(10^a+10^b) is effectively max(a,b), right?

Cᴏɴᴏʀ O'Bʀɪᴇɴ

if it is, then I'm happy

LegionMammal978

I mean, the 10^max should dominate

Zgarb

If a == b, you get log(2)*a

LegionMammal978

I know that

But say when a != b

Cᴏɴᴏʀ O'Bʀɪᴇɴ

@LegionMammal978 Roughly, yes

(I use natural log, base there)

LegionMammal978

5:39 PM

(is there a closed form expression for the exact value which doesn't calculate the exponents themselves? a and b are large in my scenario)

Cᴏɴᴏʀ O'Bʀɪᴇɴ

the exact value of max?

LegionMammal978

The exact value of log(10^a+10^b)

quartata

Why are you doing this instead of just using max? It won't be faster I don't think

I mean it's just one branch

LegionMammal978

For extra accuracy, not writing a program here ;) (although it probably doesn't matter)

Cᴏɴᴏʀ O'Bʀɪᴇɴ

Here's base 10

Or this, without cheating

Zgarb

5:49 PM

@LegionMammal978 a + log(1 + 10^(b-a)) has a smaller exponent, if a and b are close.

LegionMammal978

Oh well

(For the record, the final result was ~10^10^10^3.29)

TimmyD

That is not a small number.

That is a big number.

zʏᴀʙiɴ101

@Upgoat You now have one more bug to fix! :D

Upgoat

;-;

Cᴏɴᴏʀ O'Bʀɪᴇɴ

why :D ???

@LegionMammal978 0.5*a*sgn(a-b)+0.5*b*sgn(b-a)+a/2+b/2

Upgoat

5:54 PM

\o/ casting parsng worked fisrt try

Cᴏɴᴏʀ O'Bʀɪᴇɴ

@LegionMammal978 or 0.5*(a+b+sqrt(a^2+b^2))

Helka Homba

Can someone confirm that 1080p60 and 720p60 are the only quality settings available for youtu.be/KyBJhwJG1jQ

quartata

confirmed it's probably still processing the other qualities

Cᴏɴᴏʀ O'Bʀɪᴇɴ

that and auto

quartata

also holy shit your computer is good enough to record in 1080p 60 fps

Upgoat

5:56 PM

@HelkaHomba yes

quartata

please give me your computer

Upgoat

@HelkaHomba does minecraft have goats yet

zʏᴀʙiɴ101

@HelkaHomba I confirm.

Helka Homba

@quartata I guess but it's been 8+ hours :s

but thanks guys

@Upgoat No. But maybe I'll name a sheep Vihan and pretend

Upgoat

:D good enough 10/10

you can flip stuff upsidedown right?

quartata

5:58 PM

Pretty sure Project Zulu and Mo Creatures both have goats

@Upgoat yes with a name tag named Dinnerbone

Upgoat

name this sheep Downgoat :D

Helka Homba

We'll see :P

quartata

Can't, has to be named Dinnerbone to be rendered upside down

Helka Homba

oh yeah

El'endia Starman

@HelkaHomba That's why I didn't watch it more than a minute and a half earlier - was too slow to load. That does seem odd to me, so I expect it should be resolved sooner or later.

Upgoat

5:59 PM

@quartata -1 0/10 writing angry letter to mineecarft ;-;

quartata

I mean, I could write a plugin to make it work for the name Downgoat if you really wanted

But since it's not a goat anyways why settle for less

Helka Homba

@El'endiaStarman Sorry :/ I did upload in 4k (upsampled for reason in description) but I would have thought the lower res ones would be there by now.

Upgoat

@quartata you can use texture pack though, right to make it goat?

quartata

@Upgoat Sure but they'll still drop mutton and wool

Upgoat

;-;

quartata

6:01 PM

I suppose resource packs can rename things now

hmm lemme see

zʏᴀʙiɴ101

@Upgoat you should make a kanban.

quartata

Yeah, the item names are just in a regular Java resource bundle

zʏᴀʙiɴ101

(for Cheddar)

Upgoat

@zʏᴀʙiɴ101 a wat

quartata

@zʏᴀʙiɴ101 what is it with you and exotic project management anyways :P

I don't think Downgoat has to worry about his little Cheddar factory workers not knowing what to do

Upgoat

6:03 PM

^

my factory workers are goats so it's hard enough as-is

zʏᴀʙiɴ101

@Upgoat a kan-ban.

Kanban (development)

Kanban is a method for managing knowledge work with an emphasis on just-in-time delivery while not overloading the team members. This approach presents all participants with a full view of the process from task definition to delivery to a customer. Team members pull work from a queue. Kanban in the context of software development can mean a visual process-management system that tells what to produce, when to produce it, and how much to produce - inspired by the Toyota Production System and by Lean manufacturing. == Overview == David Anderson was among the first to formulate the Kanban Method for...

Upgoat

how does this apply to programming

zʏᴀʙiɴ101

> Kanban in the context of software development can mean a visual process-management system that tells what to produce, when to produce it, and how much to produce - inspired by the Toyota Production System and by Lean manufacturing.

quartata

That's for when you have thousands of people you know

Upgoat

I'm ok with download script

cheese takes time to age so its not really possible

Dennis

6:05 PM

@LeakyNun Well congrats, I don't think I can match (let alone beat) that.

@Upgoat I think you're doing it wrong

Upgoat

6:17 PM

um wat

quartata

I suspect it's sending me a 404

Upgoat

what command are you doing to install

quartata

The one on the Github

Upgoat

make sure you're doing: sh <(curl -fsSL cheddar.vihan.org/i/nix/cheddar)

(that's the one on the website)

quartata

you should update the readme

Upgoat

6:18 PM

yeah, I'll do that in the next merge

quartata

oh god your website is way too web 2.0

Upgoat

quartata

well at least I wouldn't have been able to tell this was made by a goat

>_> it just worked on ubuntu and centos @quartata what OS are you on?

quartata

I'll just install it by hand screw this

@Upgoat Oh wait, it's not that

It's the grunt

Oh, I know why.

You should really make it not require sudo; make them authenticate as root themselves

Upgoat

how?

quartata

Just remove every instance of sudo

Upgoat

6:24 PM

nah, people then think imma hack their computer

too much inconvinence

quartata

I'm one of those people who thinks sudo is the spawn of the devil and refuses to use it

Upgoat

:| okay... will remove in next release

quartata

As a result I ran this as root and sudoing messes up my path meaning it can't find npm

Upgoat

this commit must be nightmare then :|

TimmyD

I'm not sure you need to worry about "inconvenience" in an install for an experimental esoteric programming language.

quartata

Ooh, gets better and better

quartata

you know I could just run this directly

you really don't need this exotic install process, it's just a js file

Error: Cannot find module '/home/quartata/cdrtmp-1466101146/src/cli/repl.js'

it's clearly named as repl.es6

Upgoat

wat

that's not..

quartata

Oh shit, you gotta Babel it first. That's why you have Grunt

Upgoat

imvery confused

quartata

6:27 PM

@Upgoat I just ran node cheddar.es6 directly

Upgoat

i dont think you can do that

you'll have to run cheddar.js in the dist/ dir

quartata

Guess I'll feed these to Babel by hand and rename the files

Upgoat

@quartata what OS are you on?

quartata

@Upgoat Right, but Grunt is the worst build tool I've ever seen

Upgoat

nvm i take this statement back

quartata

6:28 PM

@Upgoat ubuntu

Upgoat

wat, works fine on c9 ubuntu

maybe manually install node (LCS) & npm

quartata

Eh, forget this. Just time the thing locally and tell me the time so I can make fun of you

@Upgoat I did

I'm using my own build of node

Upgoat

oh okay

quartata

v5.0.0

little out of date

Anyways the problem is most likely in Grunt

Upgoat

oh you're not on node LCS i think

quartata

6:30 PM

@Upgoat This isn't really a stock Ubuntu per se

Upgoat

if you have realpath or GNU readlink then it should work fine

what's node -v and npm -v?

7:03 PM

Protecting questions rarely makes sense on PPCG. However, common problems on SO and SU tend to attract Thanks, your answer helped me. or I'm having the same problem. "answers", so protecting it shields it from new users.

@LeakyNun It's rather hopeless with my current approach, but I'll take a look later.

@Dennis but sometimes very popular questions get lots lf answers by new users who don't read the rules etc.

In word processing and digital typesetting, a non-breaking space (" ") (also called no-break space, non-breakable space (NBSP), hard space, or fixed space) is a space character that prevents an automatic line break at its position. In some formats, including HTML, it also prevents consecutive whitespace characters from collapsing into a single space. In HTML, the common non-breaking space, which is the same width as the ordinary space character, is encoded as   or  . In Unicode, it is encoded as U+00A0. Non-breaking space characters with other widths also exist. == Uses and variations... ==

@LeakyNun One that uses CP437 (e.g., asciitable.com)

Leaky Nun

@LegionMammal978 CP437 is not unicdoe

PhiNotPi

@El'endiaStarman Pretty sure it's grey for America, gray for England.

@LeakyNun Was saying that a site stating that it is NBSP is using CP437

Leaky Nun

@Poke nobody's saying it's wrong

A new windows build is here (XX366). It takes a long time to install, so keep an eye on your active hours to prevent unexpected restarting.

@LeakyNun just adding my 2 cents.

LegionMammal978

@Bálint Well, CP437 was used by DOS...

Leaky Nun

@LegionMammal978 Alright.

Q: Adjust notification settings per chat room

At the top right of a chat room, just above the room title, there is a speaker icon. Clicking on this icon brings up the settings for "Sound notifications": Currently, a change to this setting affects all chat rooms. Selecting "visible room" means that an audio notification is given for any ac...

Can someone create me a RegEx, withc matches a single comma, but not multiple?

Leaky Nun

@Bálint (?<!,),(?!,)

Bálint

It can't use look before

That's my problem with it

Leaky Nun

@Bálint ^,$|^,[^,]|[^,],$|[^,],[^,]

Bálint

@LeakyNun Thank you

LegionMammal978

7:47 PM

@Bálint Note that it will also match the surrounding characters

Bálint

That's a problem

I hate how javascript doesn't support lookbefore

Leaky Nun

@Bálint ^(,)$|^(,)[^,]|[^,](,)$|[^,](,)[^,] capture groups 1 to 4 (or 0 to 3 if you suck)

Upgoat

@Bálint solution: don't use regex

Bálint

I need to split a string at every comma, but if you have 2 commas, it needs to match the second one

Upgoat

@Bálint (^|[^,]),(?!,)

@trichoplax My first reflex was to close the popup in the image=)

Bálint

So pretty much every comma, wich doesn't have a comma after it

Wait, that can be done with a negative lookahead

trichoplax

@flawr I almost did that myself, even though I posted it... Especially as the mouse pointer changes when hovering over the image

Upgoat

@Bálint what exactly is the task you're trying to accomplish?

Bálint

,(?!,)

trichoplax

7:52 PM

@Bálint Are relevant commas always followed by a space?

Upgoat

@Bálint blog.codinghorror.com/…

Bálint

@Upgoat That's not that complicated

Leaky Nun

@Bálint This works with your last description but not your first

Bálint

Yeah, I didn't express myself well enough

Leaky Nun

alright

A: Convert UTF-8 string with only 8 bits per character

You can get the ASCII value of a character with .charCodeAt(position). You can split a character into multiple characters using this. First, get the char code for every character, by looping trough the string. Create a temporary empty string, and while the char code is higher than 255 of the cur...

This is why I needed it

trichoplax

@TimmyD I know - it was a joke because of the argument that was going on over what ASCII 255 is :)

TimmyD

ASCII doesn't have 255

It's 0-127

extended ASCII does, but then it's dependent upon implementation

Oh, I see you guys have already covered that.

nvm

@TimmyD Yes they did specify extended, but it just amused me that it's still called "Standard"
