A: Cover up zeroes in a list

Pyth, 8 bytes t.u|YNQ0 Uses .u (cumulative reduce) by | (Python's or), with base case 0.

So yeah.

A: Summation from a to b

Jelly, 2 bytes rS Try it online. Takes two numbers as command-line arguments. This is non-competing since Jelly was created after this challenge.

A: Summation from a to b

Pyth, 6 4 bytes + 3 = 7 5 bytes s}vzQ Avoids the 3-byte penalty imposed by the new input requirements via an extra byte. Takes input separated from stdin separated by newlines. Live demo.

@Sp3000 (Good.)

J Atkin

I just added some debugging tools for you to use.

I don't think comparing to Pyth is a fair comparison yet, since Jelly's power currently seems to be limited within a certain scope so far

12:43 AM

@Sp3000 Emphasis on so far

It's gonna get better.

Give Dennis a few more months I reckon

Product over a range Your task is simple: given two integers a and b, output ∏[a,b); that is, the product of the range between a inclusive and b exclusive. You may take a and b in any reasonable format, whether that be arguments to a function, a list input, STDIN, et cetera. You may output in an...

There you happy

Don't depend on it.

:P

It always works for @ThomasKwa :P

12:45 AM

Wait, b exclusive?

Why did you just add a byte ;_;

Because :3

It reduces a byte in Jolf X3

That's just rude

12:58 AM

Ah

@quartata Wait... how does the rightquote only do decrement of the first argument?

I think I misunderstand Jelly.

@ThomasKwa It's decrement.

And it does the first argument, which is b in this case

So x ’rP y is ((x’) r y)P?

@ThomasKwa Yes.

In dyadic chains, monads operate only on the return value, which starts as the left argument.

Q: Minimum number of numbers to sum to exactly n

@ThomasKwa Yeah, took me a bit to figure it out.

I believe you can use @ to flip the arguments in a chain though if you need to.

This popped up on Meta SE. While the Nineteenth Byte doesn't suffer from these problems as much, I think everyone on SE should at least read this or contribute because I have seen these issues in other chats on SE

And it should be fixed

@quartata Oh no! We communicate in chat how humans do in real life and not in stiff Q&A! How horrible, it must be stopped!.

Did a newbie seriously just post integer knapsack as a golfing challenge?

This is wonderful

1:12 AM

@quintopia Er... yes..

Well I guess minimum instead of maximum....

Might be a dupe

@mınxomaτ That's not what it's saying at all

@quartata I'm overstating.

@NewMainPosts Hmm, can I do this in Jelly

I don't think its array manipulation is good enough yet.

@quartata The "issues" stated usually get resolved in the matter of minutes to hours and while they're logged permanently, communication moves on, as it always does. You don't have to create problems artificially. The problems specificially mentioned in the meta post are problems of everyday communication, nothing that can ever be resolved or improved by "editing the FAQ". (Nor will there ever be consensus among all mods in all SE chats over what is OK and what not).

1:18 AM

Let's solve a few easier problems first, @CandiedMango: if we can agree on a universal language, a universal culture, and a universal religion, then we can start talking about a universal set of vulgarities. — Shog9 ♦ 29 mins ago

I think it's already up

@Dennis I "upgraded" my browser. After toying with Chromium for OS X, I'm currently trying out Chrome. (cc @Doorknob)

It's actually much faster than Safari.

@AlexA. Jee I wonder why

\o/

1:45 AM

cough

V8 (JavaScript engine)

The V8 JavaScript Engine is an open source JavaScript engine developed by The Chromium Project for the Google Chrome web browser. It has since seen use in many other projects, such as Node.js and MongoDB that are used server side. As of 2012, the head programmer is Lars Bak. The first version of the V8 engine was released at the same time as the first version of Chrome, September 2, 2008. V8 compiles JavaScript to native machine code (IA-32, x86-64, ARM, or MIPS ISAs; has also been ported to PowerPC and IBM s390 for use in servers) before executing it, instead of more traditional techniques such...

You sure can get out a lot of words between coughs.

Did you actually base your decision on the poll?

Not really, but I do think it was helpful.

I was already leaning toward Chrome but if Firefox had more support I probably would have given it a shot.

Three of the Chrome votes may have been mine.

2

...ಠ_ಠ

1:47 AM

ha

@AlexA. Why the scare quotes?

It's the truth. :P

@Doorknob I'm scared.

I don't consider it an upgrade so much as an alternative.

Safari is still set as my default browser. I'm in skeptic mode.

@Doorknob Why do you use Chromium rather than Chrome?

open source

no Flash

bluer

in the Debian repos

Lack of Flash support is a plus for you? :P

absolutely

1:52 AM

@AlexA. For some, yes.

Flash sucks.

I don't disagree with that at all

If I didn't have to use it I wouldn't. It's a CPU hog

Piece of trash

But isn't it better to have support for it should you come across a site that uses Flash?

HTML5 will supplant it pretty soon.

@AlexA. Yeah.

@AlexA. No. If a site uses Flash, it is not worth using. :P

1:53 AM

But, it's already starting to disappear from sites.

HTML5 ʜᴀs ᴀ ʟᴏɴɢ ᴡᴀʏ ᴛᴏ ɢᴏ .-.

Most important sites use HTML5 now.

It still doesn't have the best support for games

@CᴏɴᴏʀO'Bʀɪᴇɴ No it doesn't. Chrome is very close to supporting everything in the HTML 5 standard.

@CᴏɴᴏʀO'Bʀɪᴇɴ You don't play Nethack in-browser anyway

1:54 AM

@CᴏɴᴏʀO'Bʀɪᴇɴ Canvas is actually very powerful. IIRC GameMaker Studio can export to HTML5 now.

ಠ_ಠ

@Doorknob You can, with a Java Applet at NAO

But you don't

shouldn't

Right, but it works.

Anyway, I can't run Java applets either

because they're also horrible

1:55 AM

@Doorknob Me neither :P They never fixed IcedTea

@quartata I know it's powerful

@Doorknob I actually really, really dislike the Chrome logo. I find the Chromium logo much more pleasant.

But a decent 3d shooter is so laga

@AlexA. haha, #1 reason to use Chromium

openSUSE has Pepperflash and Chrome's PDF viewer for Chromium in its repos. Without those, I'd be using Chrome.

1:55 AM

@CᴏɴᴏʀO'Bʀɪᴇɴ That's because no one has bothered to make a good WebGL engine yet.

It's doable, for sure.

@Dennis I remember Ubuntu having Pepper Flash player; not sure about Debian. But I wouldn't want it anyway :P

media.tojicode.com/q3bsp

@Dennis So you're on Chromium, not Chrome, as well?

@quartata ¯\_(ツ)_/¯ I'm still waiting for one.

Yes.

1:56 AM

If this doesn't scream potential at you, I don't know what will.

And this was made like years ago too.

@AlexA. You have to get Chrome from Google's repo instead of the distro's. That has been... suboptimal for me.

@Doorknob Apparently the only closed-source parts of Chrome are things that make little bits faster or whatever. Idk I didn't read it that closely. :P

@AlexA. The closed-source parts are the built in Pepperflash, PDF viewer and something I can't remember

OK Google?

@Dennis Google.com -> Download Chrome. It autoupdates. ¯\_(ツ)_/¯

Idk. I'll probably keep using Safari.

2:00 AM

@AlexA. No, it doesn't. Chrome updates are still handled by the package manager. That wasn't the problem though. Chrome's renderer was unstable on my system. I've never had the same problem with Chromium.

@AlexA. incorrect

@Doorknob alex-is-wrong

@AlexA. How dare you disrespect the poll's consensus? :P

@Doorknob It's not like I enable it by default. I've set all my plugins to click-to-run.

I rarely use Flash. The PDF reader is a nice addition though.

@CᴏɴᴏʀO'Bʀɪᴇɴ It does annoy me somewhat that you chose to make b exclusive because it's shorter in Jolf. Range in Minkolang includes b. How about you allow b to be either exclusive or inclusive?

@El'endiaStarman I was joking :P

2:09 AM

(Python excludes b as well.)

I thought most languages would implement an exclusive, but yeah.

Inclusive ranges are objectively the better choice.

And not just because it's a byte shorter in Jelly or anything

Please see revisions ^_^

^_^

2:12 AM

Make it exclusive so that it is sweeter when Jelly wins anyways

:P

Just kidding.

=_=

Anyway...

I'll give a +0 byte bonus if you do an exclusive, Okay?

I feel like any candidate that promised to eliminate taxes very well might win the Presidency...

2:13 AM

I think you should incorporate your answer to my comment.

Assuming there aren't enough people who realize what a horrible idea that is. :P

Paraguay just got an income tax. Can't say I'm happy.

@Dennis :/

Woah! Chrome moved the Console tab in the Inspector tool!

@Dennis What were you taxed on before? Property?

I could see a successful elimination of income tax. Just raise sales tax and give people buying credits (EBT cards) to offset the difference, inversely proportional to income.

2:18 AM

@El'endiaStarman I hear they taxed you based on the combined length of all your code-golf solutions

2

Dennis almost got arrested for tax fraud.

@El'endiaStarman Nothing, really. I mean, there were taxes (VAT, land tax), but none that resemble an income tax.

Then wouldn't you avoid taxation by not playing code golf?

@quintopia code-golf is mandatory

I shouldn't have to elaborate the joke why did you do this

Go to worldbuilding SE

It took me a long time before I understood sales taxes. That's a pretty weird idea IMHO.

@Dennis Do they not have sale tax in Paraguay?

2:20 AM

I like to beat horses til they're dead and keep beating them. But I like the idea of code golf being mandatory in Paraguay. Is half of PPCG Paraguayan?

@quartata Paraguay (and all other countries I lived in or visited) have VAT, which is a similar idea, but actually makes sense.

For example, you can't avoid VAT by buying stuff in a state from another state by mail.

@quintopia Most people here don't even have a computer, so you'll have to keep wishing.
