@NathanMerrill Lol, just finished it myself.
Giant chat challenge: given a contiguous set of cubes like Minecraft's terrain, generate a surface that "smooths it out", so to speak. Alternatively, "de-alias it" (which is not the same thing as anti-aliasing).
some of the later levels had a bit too much lotion IMO
It's surprisingly good for 3 days, though
@DrGreenEggsandHamDJ Lol, I'd be at 6.5k now if I hadn't been giving so many bounties. ಠ_ಠ
8:02 PM
@El'endiaStarman Smooth it out like marching cubes or like make the slopes less random?
@El'endiaStarman Should we take the smoothness factor as input?
@mbomb007 Hey!
@Bálint "De-aliasing" is probably a better term. When you try to display an ideal triangle on a grid of square pixels naively, you include only the pixels inside the triangle, which gives it a jagged look. Anti-aliasing mitigates this problem by making the pixels that are partially outside the triangle partially transparent. What I want is to go from the pure aliased look to the original triangle. I realize that perfection is basically impossible, but a good approximation should be possible.
@Bálint [...Array(s)].map(_=>Array(s).fill(0)), does this make it shorter? It's not reference based
@BassdropCumberwubwubwub, yes, with at leats 3 bytes, thanks very much
8:12 PM
Yay ~(^_^~)
I'm finally getting somewhere
Note: Imagine it as hills
tfw you are waiting for all your work to go through reviews and you don't want to do more work because that will just create this huge backlog of unfinished stuff
@El'endiaStarman is it called "sharpening"?
Unsharp masking (USM) is an image sharpening technique, often available in digital image processing software. The "unsharp" of the name derives from the fact that the technique uses a blurred, or "unsharp", negative image to create a mask of the original image. The unsharped mask is then combined with the positive (original) image, creating an image that is less blurry than the original. The resulting image, although clearer, may be a less accurate representation of the image's subject. In the context of signal processing, an unsharp mask is generally a linear or nonlinear filter that amplifies...
I dunno. Another way to put it is conversion from raster to vector graphics, though not in the general case.
@NathanMerrill No, that's not what I'm thinking of.
Better image, darker is higher

A: Sandbox for Proposed Challenges

Sherlock9This isn't really a challenge yet; more of an idea. Relevant discussion here. Things I'm not yet sure about include: I have two potential objectives here: find the length of any Collatz path, and given that the sequence of Collatz paths runs c(1,2), c(1,3), c(2,3), c(1,4), c(2,4), c(3,4) and ...

@El'endiaStarman I want to take something like this and make all these pieces into surfaces.
Voxel -> Mesh?
Yeah, something like that.
8:27 PM
@El'endiaStarman I mentioned marching cubes some time ago, I implemented it in java, but it's not a very small algorithm (obviously because of the huge huge lookup table)
@Poke Oooh, checking that out now.
Something seems wrong with chat search
I'm sure I've said the word "Minecraft" in here
Search seems dead indeed
@EᴀsᴛᴇʀʟʏIʀᴋ it's not a problem. ^_^
A: Sandbox for Proposed Challenges

Sherlock9Walk across a Ulam spiral Given a Ulam spiral, a spiral of integers on a rectangular grid starting from 1 at the origin, 2 at (0,1), 3 at (1,1), and so on, write a function that returns one of the shortest possible paths between two numbers on this grid where you can make orthogonal and diagonal...

8:43 PM
Can someone else confirm chat search not working - chat.stackexchange.com/search?q=this&room=240
It doesn't
Confirmed not working
When will i reach 1k :(
@CᴏɴᴏʀO'Bʀɪᴇɴ :D
@HelkaHomba yes, it's been dead.
8:49 PM
Q: Chat Search is Currently Broken

Helka HombaSearching any Stack Exchange chatroom doesn't seem to work at the moment. For example the word "this" certainly appears in The Nineteenth Byte but https://chat.stackexchange.com/search?q=this&room=240 results in 0 messages found for me. Even with the user specified there are no results: http...

@HelkaHomba It doesn't for me, too.
it doesn't work for anybody
@Poke This is tantalizingly close to what I want, but I'm not sure how to apply to to the specific generation method I have. The picture posted above was generated from a biased 3D majority rule.
@MartinBüttner Finally remembered to put those challenges we discussed last month in the Sandbox; here's Collatz paths, traversing a Ulam spiral, and traversing Apollonian gaskets
If anyone else would like to look at my Sandbox posts, I'd be happy to read suggestions for them. They're rough drafts right now and written very early in the morning for me.
We're aware and it's currently being investigated. — bluefeet ♦ 1 min ago
8:57 PM
Any help with being clear, not taking thing for granted and forgetting to explain them and other such suggestions are most appreciated :)
Yeah, it happens once in a while, think it's at least the third time in the last year or so. — Shadow Wizard 2 mins ago
A: Sandbox for Proposed Challenges

Sherlock9Inspired by this discussion on challenge ideas. See the message linked and some of the messages below it. Pictures to follow as soon as I figure out how to generate them. Traversing Apollonian Gaskets: Walking Around in Circles path-finding Inspired by Martin Büttner`s challenge Help, I'm tra...

Aaaaand the Shadow Wizard retitles the post, just as with most posts on the Meta. :P
Q: Include a JavaScript script with JavaScript

AdiTo dynamically include a JavaScript file in a web page, you'd normally insert a <script> tag pointing to your script. For example: var js_file= document.createElement("script"); js_file.src='http://example.com/js.js'; document.body.appendChild(js_file); Write JavaScript code will load an exter...

@Sherlock9 Just an idea that the minimum-sum path might be neat for the Ulam one. Harder though of course
9:07 PM
@HelkaHomba Peter Taylor told me it's not a Ulam spiral. That contains only primes. I meant a regular spiral. More to the point, a minimum-sum path could work
Right, I just mean the plain spiral
I edited the challenge
@Bálint Too many spam cloud pics.... like 4 in an hour wow
@HelkaHomba Apologies for having mushy brains tonight with my definitions and explanations. It's 4 in the morning here
Can someone help me with how to do a list comprehension in pyth?
Say I have list [2, 3, 5] how can I add 1 to each to get [3, 4, 6]
in raw python it would be ` [x+1 for x in someList]`
9:15 PM
@HelkaHomba Should I stick to the easier version or try the minimum sum? I don't want it to be too hard.
@BaldBantha 4 in an hour is not bad at all. I've seen 4 in a minute. :P
@Keatinge hM is increment-map.
In general, you can use m to map. mhd (d is the implicit lambda) would work as well.
No answer...
lol I got a downvote on a question that was purely salt
Not working..
9:24 PM
@Dennis Thanks but could you give me an example of how to implement it for a list like {P How could I do it to add 999 to each item in list. m{P+999 is creating a bunch of random lists. I want to add 999 to each number in the list
@Keatinge That would be m+d999{P.
@Dennis Thanks that works great
askseriously.tk disagrees O_O
s/<insert question here>/I said zyabinVI before/
A: Chat search is returning no results

AdamI don't know where the analyzer config went for that specific index, but it was missing. We're rebuilding the chat-stackexchange index, which will take some time to complete (probably under an hour or so?). Once that's done, searches should be fine again.

Heh, still going up. Index is still rebuilding.
9:43 PM
0:43 here.
I played Nethack for the first time last night
@Quill Care to share how is it?
At first I was like "WTF" and then after a little while I was still like "WTF" (but a good kind of WTF)
How's your progress? Screens, dumps, ttyrecs?
9:46 PM
@Quill yep, sounds about right
@zyabin101 I just hit no for those
I got surrounded by a gnome army and their king or something killed me after like the ninth gnome
@Quill Even DYWYPI?? D:
@zyabin101 Don't you want your potato infection??
Get out while you can still speak in full words!
@Quill Do you want your possesions identified? >_>
9:52 PM
@zyabin101 Developing youths win your picking interests?
@CᴏɴᴏʀO'Bʀɪᴇɴ ^^
Don't yell words your parents invented
I don't because Mom didn't invent any words. :P
You like it?
10:00 PM
I think so
you should play dNethack, a fun variant of nethack.
Is normal Nethack not fun?
you can try it online ( sorry dennis ) here
@Quill yeah, but that doesn't mean it is the funnest it can be. :P
@EᴀsᴛᴇʀʟʏIʀᴋ that URL
Like CR is fun, but it could be funner with more .
@Quill ikr
@Quill go to dank.ninja
^ for starring purposes
10:03 PM
@EᴀsᴛᴇʀʟʏIʀᴋ that's on-topic, we just don't have many reviewers who specialise in that <_<
> We are anonymouse, we forgive and forget, and steal cheese
@Quill yeah
damnit people, really star that?
10:15 PM
@Sherlock9 Are you still around?
@Quill Let me know next time you get a question on that.

@PhiNotPi what is a bodily awareness meme?
10:54 PM
I'm torn on whether to forbid such built ins:
Maybe ban base-conversion built-ins (including toString() functions)? — Peter Taylor 9 hours ago
Any suggestions/thoughts?
not in favour of it
The ban or the built in?
Part of me feels that trivial challenges should be trivial - if you don't want trivial built in solutions then don't write a trivial challenge
11:06 PM
there are some way to get around it and to have almost the same bytecount
Q: var_dump all defined variables except superglobals in PHP

VarunAgwThis task is to create shortest code to var_dump the output of get_defined_vars() excluding all the superglobals Whitespace, new lines, everything counts.

11:24 PM
A friend asked me to speed her computer up. Installed CCleaner and ran it. It found TEN GIGABYTES to remove on the first run through.
Wait, scratch that, 13.
I know, it's horrifying.
It's got a shitty dual core 2 GHZ amd cpu.
what the ಠ_ಠ was she doing to that poor computer
hey, that works pretty well as a cuss
what the ಠ_ಠ
@DrGreenEggsandHamDJ are you starring the O_O? If so, star ^ instead please.
11:29 PM
I starred neither.

11:45 PM
@Fatalize I have a Prolog question
11:56 PM
Q: How much TnT do you need to destroy the Asian continent

HajharExactly how much Tnt do you need to destroy the asian continent

Can anyone who is better at Prolog than me tell me why this doesn't work? The goal immediately fails regardless of what the first character is:
X \== end_of_file,
(X == 'a'; X == 'b'),
Y \== end_of_file,
Y == 'c'.
I feel like this is something super obvious and I'm just being dumb...
