The Nineteenth Byte

ooh, I see ES2018 is getting .NET-style lookbehind assertions

Deadcode

@Neil Has gotten.

Neil

well, it's not widely available

Deadcode

@Neil Really? It's in the latest versions of Firefox and Chrome.

@Neil Did you see what I did with your 36 byte suggestion?

Neil

well it doesn't even seem to have reached developer edition yet, I just get invalid group if I try

Deadcode

@Neil Of what? Firefox or Chrome?

Neil

00:42

firefox

ah, I thought there must be a way to avoid that duplication - an atomic group does the trick, very nice

Yay I did a lot of golfing today

@Neil Wow, ECMAScript is about as bad as C++ with year versioning :P

ASCII-only

@MilkyWay90 what's with that code

just a bunch of moves?

@MilkyWay90 tio the bruteforcer pls

Deadcode

@MilkyWay90 I noticed you were talking about brute forcing to come up with this code. Would you be able to perfectly optimize it if you calculated an inverse for the PRNG function? I've done that with a few PRNGs.

ASCII-only

02:22

@Deadcode well iirc python's prng has a massive state which you can set the entirety/most of with a seed

which is how the Seed answers were made

Quintec

@MilkyWay90 Did golfing, or brute-forcing with larger numbers? :P

ASCII-only

@Quintec well. the programs are shorter

MilkyWay90

02:37

@Deadcode guess so

pastebin.com/Z5z0Ai7Y

for the tio link

Deadcode

Is that preferred to using URL-shorteners?

MilkyWay90

oh i dunno

The code is here

In case the TIO link is too long

It is probably highly ineffecient

Please improve it when you have the chance, if you want to

Quintec

@Deadcode Not really, but there's this

Deadcode

Well I mean for chat. There's no reason to use shorteners in questions/posts.

Quintec

> are often used to obscure spam or malicious links.

Still applicable somewhat

Personally in chat/comments I always just put it into bit.ly

Deadcode

02:42

You can edit the URL of most shorteners to preview the link.

MilkyWay90

@Quintec's correct

Deadcode

Example use of bit.ly: I just found out that unsafe code in C# can actually be much faster. safe version / unsafe version (those are both shortened TIO URLs)

noɥʇʎԀʎzɐɹƆ

The canonical PPCG complexity of a particular computational problem is the number of bytes PPCG can solve the problem with plus one, given the language used to solve the problem is one of the top 256 most popular on PPCG.

MilkyWay90

@Deadcode Oh nice

I wish bit.ly added a feature where it tells you where you are going and you have the option to cancel going to the link

Deadcode

@noɥʇʎԀʎzɐɹƆ You'd also need a time index, because the list of 256 most popular probably changes over time.

@MilkyWay90 It does. Just add a + at the end of the link.

MilkyWay90

02:50

oh

I made another bruteforcer It takes really long, but it results in less bytecount at the end

Jo King

@noɥʇʎԀʎzɐɹƆ Popular isn't an objective winning criterion :P

Quintec

@Deadcode The problem is that takes me 3-4 extra clicks, right-click + copy link + paste link... I'm lazy. :P

Deadcode

@Quintec There's probably a browser plugin to automate adding the +

Quintec

True, and if not it wouldn't take long to code... but how much time am I really saving doing this? Lemme waste another 5 minutes calculating it. :P

@Deadcode It would be funny if the link you sent us was a shortened url

Deadcode

:P

@MilkyWay90 how to stop it

@Adám because the question is community wiki. why that is, idk

For some years now, the number of students in my school has been growing steadily.

14:31

@Adám eh, it's kind of boring to give rep just because one knows APL

Adám

@dzaima I don't understand. Did you mean "get" rather than "give"?

dzaima

@Adám I meant as in you giving rep, but replacing with get also works ¯\_(ツ)_/¯

Adám

@dzaima Lots of bounties are for specific language answers only.

dzaima

@Adám but most have a difficulty factor other than just the language (or the language is the difficulty factor, but I don't think that's what you've intended)

Dennis

Yesterday, I found out that I was misinformed: in contrast to my next door-neighbor, fiber-optic internet is available in my house. They installed it an hour ago; it achieves 60 / 10 Mbps down/up, with 12 ms latency. That my not be much by today's standards, but I was using a 6 / 0.5 Mbps down/up, high-latency ADSL connection, that randomly stopped working well—or at all, like right now—sometimes for months at a time.

I had never even tried internet this fast before. Now I have it in my house. I am literally crying out of happiness.

If you never typed into your SSH terminal and had to wait for seconds for the characters to appear on the screen, you may not understand, but working on TIO was considerably less fun that way...

AdmBorkBork

Nice! Congrats and welcome to the future!

Quintec

15:23

@Adám Why "posted before 2019" rather than "posted before this date"?

J. Sallé

@Dennis happens a lot here. Both my next-door neighbours had fiber optic internet for years before we managed to put it in our house, where the same company said it was unavailable.

Adám

@Quintec Then I'd have to reward every single APL answer going forward.

Dennis

15:40

@J.Sallé They would have refused to put the router in my kitchen. Too far away from the technician referred to as aparato (device).

He also called the router aparato. It may be the same or a different kind of aparato.

J. Sallé

@Dennis ROFL aparato is a great word to describe basically anything IT related

PhiNotPi

PPCG should make its own internet.

J. Sallé

It means the same in Portuguese, but it's very underused IMO

@PhiNotPi only if the source code is in Jelly

Adám

@J.Sallé Danish has the cognate apparat which means device or "thingy".

J. Sallé

@Adám same as in German, iirc

Erik the Outgolfer

16:22

@NewBountiesWithNoDeadlines wait a second... yeah, I don't think that should be a CW...

Riker

it's CW because the question is CW?

Erik the Outgolfer

yes, the question shouldn't be CW anymore ;)

Riker

any reason why not?

Erik the Outgolfer

the question post itself isn't so much of a W that a bigger part of the C (with at least 100 rep, that is) needs to be able to edit it :P

Adám

16:40

@Riker Is CWfying undoable?

Dennis

@Adám Yes, that's a mod power. Should I un-wiki the bounty thread?

Adám

@Dennis I think so. It was probably an oversight when the ToC was removed.

Arnauld

@Dennis Is that with a Wifi connection or wired? I have 35Mb down / 35Mb up / 3ms latency in Wifi (which I'm using most of the time), but 600Mb down / 300Mb up / 3ms latency when wired. (This is a FTTH connection.)

J. Sallé

@Arnauld this is what I want in my life.

want/need

Dennis

16:57

@Adám It should probably be re-added (not all bounties from the question were in the answer list), but a CW answer would suite that purpose better.

I've removed the wiki. I'll add the answer later, if nobody beats me to it.

Dennis

@Arnauld Wired. I haven't measured the WiFi yet.

Arnauld

@J.Sallé I think that Internet in France is rather efficient and cheap, compared to other countries. (I pay 40 EUR/month for the fiber connection, which comes with unlimited phone calls and tons of TV channels.)

Erik the Outgolfer

@Dennis getting rid of the LBWND directory...

Adám

@NewMainPosts Maybe if we get a goofy design featuring something very sport-themed, that will discourage general programming ~~questions~~ support calls.

@Arnauld Similar here in the UK.

Dennis

17:04

@Dennis Roughly the same over WiFi.

Arnauld

17:21

@Dennis 60 Mbps down in WiFi is pretty good. (Fun fact: on the same connection, my phone uploads faster than it downloads.)

Dennis

Yeah, the WiFi is much better than with my old router, for local networking as well.

AdmBorkBork

17:57

Wow, I'm jealous. I pay about 100USD for 150 down / 50 up, and that's a pretty good bargain.

Erik the Outgolfer

I pay a little bit over 25EUR per month for (non-fiber) 12 down / 2 up (IIRC)... they haven't installed fiber here yet

Dennis

I'm paying USD 32 per month, which is USD 3 less than I was paying for the ADSL connection.

PhiNotPi

18:12

Speedtest says 50 down, 20 up for my apartment. Internet is included in my rent so I don't know how much I'm paying for it, but I know I am.

Erik the Outgolfer

who provides you the Internet?

also, I think you have the right to know what you're paying for

PhiNotPi

Elauwit, AKA Spectrum

Erik the Outgolfer

but is it the apartment's owner who directly provides the service to you?

PhiNotPi

yeah, it's all wired together I assume

Erik the Outgolfer

because, in our apartment, it's us who pay the ISP directly

CMP Best online regex tool for testing/learning. I've been using RegExr, and it's been working pretty well, just wondering if there's something better out there.

Quintec

In addition to ^, any good online regex lessons with examples, exercises, etc.?

Deadcode

@AdmBorkBork Regex101 is another excellent one. Is there anything RegExr has that it doesn't?

@Quintec Regex101 has a quiz.

I learned a lot about PCRE doing that quiz.

AdmBorkBork

Oh nice. I'll have to look that up later.

The cheatsheet on Regex101 looks more in-depth than the one on RegExr

regex101 also has site themes

because they care :]

my only problem with regex101 is that it colors special chars by background rather than foreground, and i absolutely hate anything that does that
