4:00 PM

[^b]b+[^b] or [^b]b{m,n}[^b]?

Eᴀsᴛᴇʀʟʏ Iʀᴋ

Then bb => b+

Where m, n are integers.

Eᴀsᴛᴇʀʟʏ Iʀᴋ

That's more than one but any number of b

@TimmyD for any number of b but at least 1: [^b]b+[^b]

Yep, got all that, that works for the match portion. How about the replacement portion?

Eᴀsᴛᴇʀʟʏ Iʀᴋ

Replace with what?

Just remove the inner bit?

4:02 PM

I'm intending to turn, for example, bbbaabbab into bbbaaqqab.

Does your regex flavour have lookahead/lookbehind?

Eᴀsᴛᴇʀʟʏ Iʀᴋ

^

If not, it's impossible afaik

TùxCräftîñg

p=s=>((t=s.shift())=='<'||t=='>')?[t,p(s),p(s)]:t
f=a=>a[0]=='<'?a[1]:a[0]=='>'?a[2]:a[0]
s=>f(p([...s]))

@Lynn ES6, 105 bytes

Yeah, it's .NET

Eᴀsᴛᴇʀʟʏ Iʀᴋ

You'd need to find how many b are in the middle, idk how to do that.

Ask martin.

4:05 PM

Yeah. Regex is one of the areas I really struggle with.

TùxCräftîñg

oh nvm it's invalid

Eᴀsᴛᴇʀʟʏ Iʀᴋ

It's not hard except for lookaheads and lookbehinds.

Retina tells me this works: (?<=[^b].*?)b(?=.*?[^b]) => desired letter

TùxCräftîñg

valid, 111 bytes:

p=s=>((t=s.shift())=='<'||t=='>')?[t,p(s),p(s)]:t
f=a=>a[0]=='<'?f(a[1]):a[0]=='>'?f(a[2]):a[0]
s=>f(p([...s]))

@Lynn as one of the few other Vim-golfers, I'm curious: what do you think of V? I've been wondering if it's really cheap to throw a bunch of mappings on an already golfy language and call it a new language.

4:07 PM

CJam comes to mind

With convex?

Even shorter GolfScript

Oh. Isn't convex even shorter cjam?

I don't know anything about it

I suppose it is

Not a bad idea considering CJam has a bunch of 2-letter operators and has explicit input

@BusinessCat Awesome, I think that might do it. Let me play around with it a bit.

4:12 PM

And Convex has Regex?!

Why am I still using CJam

@DJMcMayhem I don’t think I would ever pick it over Vim

TùxCräftîñg

V need Neovim and Neovim dont work on windows :/

@TùxCräftîñg it sorta does, it's just a pain

TùxCräftîñg

what is divmod?

4:27 PM

You get the div and the mod

I think

Honestly, the only golf-y language I like to use anymore is Jelly, because it’s so ridiculously fun/novel/powerful. I otherwise prefer to use languages “most people” can appreciate

El'endia Starman

Yeah, the quick way to get the mod is to divide, and in the process of dividing, you often pretty much get the mod for free, so divmod is pretty efficient in most cases.

@Lynn You use Vim though...

Well, ~~I like to annoy Emacs users~~ a lot of people use Vim.

Who actually uses emacs

4:32 PM

@Lynn that's sad but I can't really blame you...

Who actually uses Vim

o/

Some people do, oddly enough

TùxCräftîñg

@Fatalize sane people

@TùxCräftîñg You forgot to type in

4:34 PM

People who don't own a mouse

@Fatalize Lynn, me, doorknob, Alex, downgoat, easterly, others

in my first job that put me on a linux machine, they also used Emacs, so I did as well

TùxCräftîñg

ಠ_ಠ_ಠ

And tux

who uses emacs?

4:36 PM

@muddyfish there are dozens of people who use emacs!

Probably

I think

There are dozens of us... DOZENS

3

Well I was going to make a poll but strawpoll kept saying I needed a title when I put one in

El'endia Starman

@Fatalize I see a lot more Vim usage in here than Emacs. :P

Haha, I just got mortarboard on meta. I didn't think that was possible.

4:39 PM

Who actually uses Vim or Emacs

should be the question

^

My point exactly

El'endia Starman

@Fatalize I do.

TùxCräftîñg

@Fatalize sane people

They are both terrible editors

El'endia Starman

DJ does, Doorknob does, Lynn does, etc...

4:39 PM

@Fatalize you might as well just ask "who actually uses vim"

TùxCräftîñg

@BusinessCat ಠ_ಠ

<grabs popcorn>

I use Vim and it’s pretty terrible

I bet Emacs is also terrible!

Both are powerful though

TùxCräftîñg

^

@NathanMerrill Do you have time to test something (and download ~300MB)?

TùxCräftîñg

4:41 PM

Emacs is even more golfy sometimes

Do you like "difficult" editors?

But I'm seriously wondering because I have never heard anybody actually say they use emacs

Uhh... why

TùxCräftîñg

2G<C-a>

When you combine the two sides, you get something that everyone hates

4:43 PM

I wish I could vote “meh” on this poll

Dangit, ninja'd

Probably the text editor I’m most excited about right now is Kakoune!

@Lynn Do you actually use it?

Which is just modal Sublime Text, kinda? And does away with most of Vim’s really weird crap

I started using it a couple of days ago :>

Best editor was GW-BASIC interpreter style. Everything since has been a letdown.

4:45 PM

Sublime is just SciTe with more bells and whistles. Not as bloated as Atom though.

IDEs that can actually reason about your code are also nice. I probably couldn’t program Java without IntelliJ

Google tells me to just deal with it :(

Well, IDEs that run on static analysis platforms, like JetBrain's Rider.

The problem IMO is that Vim and friends try to save time in naïve text “micro-management”. If you have smart IDE features, basically the rest of your text editor can be Notepad and it will still kick ass.

Releasing Helium Nuclei

@Lynn vim has GREAT plugins

4:47 PM

@HelkaHomba That looks like a regular albeit active forum user. No indication that the reply is from Google.

True; I’ve never looked into those much. I got a Python plugin one and it annoyed me. ;-;

@Lynn that's why my favorite ide is vsvim. All the benefits of Vim mixed the features of an ide

Yeah, VsVim looks neat

*mixed with

It's not perfect though. Normal mode is great but the ex side is seriously lacking

@mınxomaτ sure

Releasing Helium Nuclei

4:54 PM

how's your desktop

^ huh?

Releasing Helium Nuclei

^ what you use on your desktop/laptop

@ReleasingHeliumNuclei I don't understand the options

ok, but the answers don't make any sense (ninja'd..)

Releasing Helium Nuclei

Are you using a Window Manager, a Desktop Environment or standard Windows desktop?

4:57 PM

@ReleasingHeliumNuclei You can use a WM and a DE at the same time

Releasing Helium Nuclei

@DJMcMayhem ;_;

s/can//

And some people can use neither

Releasing Helium Nuclei

;_ ;_;

@ReleasingHeliumNuclei that's what I thought it might mean, but it's still confusing as hell

Right now I'm a MS peasant

And what do mac users answer?

Releasing Helium Nuclei

4:59 PM

@DJMcMayhem if they don't, they can't be here. i can't log in on cli browsers

@DJMcMayhem mac haz a de and a wm can be installed

No choice is applicable to me since I'm not a peasant

All three apply to me, I guess. I’m on Windows, which has a perfectly fine window manager (dwm.exe), and a perfectly fine desktop environment (Aero).

let me try to make my first poll :p

Why not just do a poll that's Windows, Linux, or Mac

Or something

OS POLL!

Releasing Helium Nuclei

5:02 PM

@BusinessCat BSD!eleven

@DJMcMayhem isn't OS X macOS now

bah, too much work

@NathanMerrill You can try out alwsl. Clone the dev branch (or just download alwsl.bat). Running without arguments (from a console) will print usage infos. alwsl install will install (backup any files from your current WSL if you have to, because it'll be reset.)

Idk idc

Don’t you mean GNU/Linux—okay, okay, I can’t keep a straight face and say that.

@DJMcMayhem I duel boot

5:03 PM

@mınxomaτ I'm assuming I don't clone from within my WLS filesystem

I use Windows since it's far less annoying to emulate Linux for the things I use it for than the other way around

@NathanMerrill haha, no.

@BusinessCat I’m in the same boat

Releasing Helium Nuclei

@Lynn I'd just like to intercept for a moment.

Aww, being on a boat sounds good right now. Nice day out.

5:04 PM

@NathanMerrill I tried it in a clean Win10 VM and it installed fine. That's the best testing I can do.

Who said OS X ಠ_ಠ

the most recent commit is dev 2 days ago?

Yep, that's ok.

I just didn't have time to test it on a clean system until now.

If you want to be on the safe side, run alwsl remove before alwsl install.

(if you get a checksum mismatch, just accept to force the install, that's a non-critical error)

I've been trying to pull the branch develop

till I double checked, and realized its called dev

-.-

Well, I said "dev" :-)

5:14 PM

I know. At work we use develop exclusively, so I'm used to that

El'endia Starman

I just did a query with TNBDE and it seems like Tux is the only one that uses emacs (exhibit A, exhibit B, query).

TNBDE > strawpoll

@El'endiaStarman I was wondering, has anyone written a query yet to get all the vandalised feed bot posts?

Hm, I usually use "unstable" as the dev branch. Dunno why I did "dev" here.

They're near impossible to search for with built-in chat search, but I'm sure I missed some good ones.

El'endia Starman

5:20 PM

@MartinEnder That's easy, actually.

@muddyfish you fight with your OS? Haha

El'endia Starman

@MartinEnder Posts by New Main Posts, New Meta Posts, or New Sandboxed Posts that aren't oneboxes.

@El'endiaStarman neat :)

@El'endiaStarman Could you sort those most starred first...?

> I am slow and I feel bad about myself

5:24 PM

Actually reading them in posted order is interesting...

El'endia Starman

@trichoplax Sorted by stars.

Turns out my "Help I'm trapped" joke wasn't all that original...

(as far as feed bot post messages go...)

@El'endiaStarman Even better! :)

El'endia Starman

Might as well include the date.

@mınxomaτ I ran the command without elevation, and I only knew something went wrong at the very end when it checked to see if Ubuntu was still installed

perhaps an elevation check?

5:26 PM

It should run without any elevation.

hmmm

Can you post the log?

Releasing Helium Nuclei

what are the most started posts, can you make a query for that?

you mean starred?

Releasing Helium Nuclei

5:27 PM

Ye

SE already provides that I think

@NathanMerrill Run alwsl install again. "0x80070091" means Microsoft fucked up.

Releasing Helium Nuclei

Stupid autocorrect ;_;

El'endia Starman

@ReleasingHeliumNuclei Top 25 most starred TNB messages.

Unfortunately, there's no way to really check for these pesky 0x800 "errors" yet.

5:28 PM

that's fine

Releasing Helium Nuclei

@El'endiaStarman most starred one is so meta

El'endia Starman

@NathanMerrill They do provide a list of starred messages, but I don't see a way to sort them.

@ReleasingHeliumNuclei It's actually the most starred message in the SE chat network.

Releasing Helium Nuclei

@El'endiaStarman just...wow

It's at 90 stars now too I think

it keeps going up

Releasing Helium Nuclei

@BusinessCat 92

5:31 PM

Even better

Why is it still going up??

El'endia Starman

....aww crap, I just realized that my transcript parser didn't note the messages with one star as they don't have a "1" in the HTML.

@El'endiaStarman idea: disable the uid and mid tables from being queried. When name or content are queried, automatically include them, then hide them from the output (and link the name/content)

@mınxomaτ I made it further...currently unsquashing rootfs

El'endia Starman

@NathanMerrill Auto-linking name doesn't work since there are six pairs of users that have had the same name in the past.

@NathanMerrill yay

Releasing Helium Nuclei

5:39 PM

brb

@El'endiaStarman it does work if you include the uid in the query

I'll try to come up with some way of checking the MS error things.

El'endia Starman

I don't even know that I can disable querying of uid and mid.

Rohan Jhunjhunwala

5:39 PM

</self-promotion>

basically, if you see SELECT name, you automatically put , uid in the query

Rohan Jhunjhunwala

(In all seriousness I am interested in seeing a discussion about that above linked topic, because I have seen it in multiple places (besides the sandbox)

El'endia Starman

@NathanMerrill I feel like that's fraught with danger though.

A fully correct solution would have to parse SQL.

you don't ?

Q: Legal to use Pokemon, etc as Themes for Challenges?

In the Golf/Puzzle Lab, I came up with an idea to create a Pokemon Emerald Battle Factory KotH. However, I had some concerns on the legality. The closest thing I could find from Nintendo is the IP Requests and Game Submission Ideas: We appreciate the interest in Nintendo and in all our video...

Worth a read

5:41 PM

I thought you prevented SQL abuses?

El'endia Starman

@NathanMerrill No, I just run it with a user that has only read-only access.

ah.

and since you don't have sensitive data, you don't need to parse selects

yeah, you'd need a SQL parser

Rohan Jhunjhunwala

@Geobits should I close my question as a dupe? It seems like that is similar, but it seems to be a much tighter question. Are they different enough? I think they are, but what is your opinion?

Unsure. I haven't voted on it either way yet.

@RohanJhunjhunwala the core "rules" to a game cannot be copyrighted.

Rohan Jhunjhunwala

5:44 PM

@NathanMerrill but can the name be copyrighted?

Like Stratego?

@RohanJhunjhunwala Yours is about playing the game rather than using the characters/themes, so although similar I'd be interested to see what people say about it.

Oh sure, the name is almost always protected.

aka, you could make a "monopoly" KoTH, but your property names had better be different, and possibly the property values as well

ideas cannot be copyrighted, but expressions of those ideas can

Rohan Jhunjhunwala

@NathanMerrill ok, thanks, that is what I would believe too. I feel like an Ai study of a game isn't violating copyright

Of course, that assumes that Company Y is going to care at all. They probably won't, or ever even hear of it. But if you want to be safe, then you should rename things at minimum.

Rohan Jhunjhunwala

5:45 PM

But it would be interestign t osee a policy of how to deal with it (i.e changing the name)

Q: How closely can a game legally resemble another?

Most games build on other games' successes and many are downright clones. Where is the limit of imitation before legal issues come into play? Is it down to literary or graphic work like characters and storyline that cause legal problems, or can someone actually claim to own gameplay mechanics? T...

@Geobits yeah, that was one of my side questions.

\o/

@NathanMerrill Might be worth linking to that in a comment on the meta post

5:48 PM

@RohanJhunjhunwala I'm pretty sure most leagues/clubs use "disc golf" in the first place for that reason.

Or frolf

ls: cannot access 'hiberfil.sys': Permission denied
ls: cannot access 'pagefile.sys': Permission denied
ls: cannot access 'swapfile.sys': Permission denied

@BusinessCat Just wanted to thank you again for that regex assist. You saved me ~67 bytes.

@BusinessCat Please tell me nobody actually uses that :/

Rohan Jhunjhunwala

wtf is frolf?

5:49 PM

Frisbee golf

FRisbee gOLF

@TimmyD No problem :)

Oh I love frisbee golf

its quite fun

Hello from Mom's phone ;^;

@NathanMerrill Next step: Create a unix user, add them to sudoers. Then use alwsl user default USERNAME to set them as the bash user. Update the system using yaourt / pacman. And try out the backup features (alwsl snapshot).

5:49 PM

@Geobits Very common term where I live.

Huh, never heard it. Do you live near a bunch of hippies? :P

Ya know, near Alex.

@NathanMerrill Uhm, what directory did you run alwsl from? You didn't run it as admin, did you?

@Geobits No, but I live right next to several frolf fields

Frolf just seems terribly awkward to pronounce.

Maybe it's just me.

@mınxomaτ I did run it as admin

5:51 PM

What the frolf??

4

and I ran the bat file from /c/alwsl

@NathanMerrill Don't do that. It isn't required and exposes you to security risks (because running a bat as admin executes it in the systemroot.

Dammit, I take five seconds to answer a text and miss the deleted message :(

right, I got that, but I was already mid-install when you said it wasn't necessary

@NathanMerrill It shouldn't cause any problems, but that's where the ls error comes from.

@Geobits I can't tell you what you missed, but I can tell you you didn't miss anything you'd mind missing...

@mınxomaτ why would that cause permission denied errors?

@NathanMerrill Because bash itself wasn't elevated to SYSTEM. Only SYSTEM can access such high priority files as e.g. the hibernation state driver.

Even for reads.

ok, reinstalling then

@trichoplax Thanks, the tension was unbearable. My mind is at ease now.

5:55 PM

@NathanMerrill Technically, there's nothing wrong with your installation.

The deleted bits are not always the best bits

@mınxomaτ I don't want warnings every time I ls

totally worth the time to reinstall

@trichoplax True, but sometimes you find a diamond in the rough ;)

@NathanMerrill That's what you get anyway, in any WSL system. You are currently in your system folder. cd somewhere else, like ~

5:56 PM

@Geobits Oh yes - it's always worth looking just in case...

:/

wait, why was my system folder in /c/alwsl?

Or just click the "archlinux" shortcut in the start menu.

is that where everything goes?

That's your home dir.

5:58 PM

oh, I think I understand. "executes it in the systemroot" means literally in the systemroot folder

But yeah, it would probably be a good idea to alwsl remove and then save alwsl somewhere safe, like in your Documents folder, or the User folder and run it again as a normal user.

I'm going to add that as an important note to the documentation to prevent confusion.
