@NewMainPosts ooo jolf will be killer at this
 
@somebody I don't know how to do a two-way wire crossing yet.
 
@Calvin'sHobbies I'd rather have a separate challenge for each person (and it's fine if you only do one of them... or none if you don't want to, of course).
 
What other popular catalog style challenges are there like codegolf.stackexchange.com/questions/55422/hello-world that allow languages made after the challenge?
 
@El'endiaStarman you could also use single-letter names, converting them to the regular names in the code, encode the grid as a series of symbols, such as <X><Y><RULE>, where <RULE> is a base-36 (say) number.
@Calvin'sHobbies "Greetings, <name>!"
 
@Calvin'sHobbies primes, cat, truth machine (at the very least)
 
7:08 PM
FizzBuzz
 
oh yeah, and 99bob
 
@MartinBüttner What did Elendia and Stewie win again?
 
Ell, not Elendia
 
thanks @Mar @Tim
 
@Calvin'sHobbies I didn't win anything. :(
 
7:09 PM
Ell won Labour of Love with Sprocket Science
 
I was third or fourth on Labor of Love.
 
You should've been first ._.
 
Stewie won Less is More with versatile integer printer
 
That took one heck of a lot of effort ^^^
 
@MartinBüttner Oh, no wonder I was confused
 
7:09 PM
@Mar@Tim = MarTim ~~ Martin
 
@CᴏɴᴏʀO'Bʀɪᴇɴ I'm happy I was nominated, and that I did as well as I did. :)
 
@mbomb007 nice job on the 19 bytes. what I had in mind was making them available for subsequent computation (so you couldn't print them individually), but I didn't specify that. regarding the bug, I think it's more likely that it was problem with TIO.
 
@El'endiaStarman \o/
 
Besides, I can't really complain too much when I have > 50 votes on the Spacewar! KotH. :P
 
@Sp3000 k, I'll sort something out
 
7:12 PM
I need to have a really good challenge idea :|
Speak of the devil.
 
@CᴏɴᴏʀO'Bʀɪᴇɴ ಠ_ಠ
 
@CᴏɴᴏʀO'Bʀɪᴇɴ Look for patterns that make you go "Hmm, that's funny."
 
@El'endiaStarman That's it? Huh boy I have so much material
half sarcasm
 
@CᴏɴᴏʀO'Bʀɪᴇɴ That's basically what my bouncing electrons challenge was.
 
7:13 PM
brace yourselves for the flood of lolcats challenges
 
@CᴏɴᴏʀO'Bʀɪᴇɴ Press "random page" in Wikipedia until it gives you something usable.
 
@El'endiaStarman Oh, I see.
 
@Zgarb or do the same on OEIS
 
@Zgarb Much better than doing math homework. I'll be gone for a while. :D

Salına Salına Sinsice, (English Meandered İnsidiously in Turkish) is the fourth single taken from Tarkan's 1997 album Ölürüm Sana. Lyrics and music were credited to Tarkan; although it was a much-loved song at the time of its release, there was some confusion as to who wrote it. The song rose up the Billboard Hot 100 in the singers' native land of Turkey. == Video clip == In addition, clip, Metin Arolat 's the song of Tarkan hairstyle and clothes, 2000, fashion, famous artists of the 1990s made specifically for the space used for decorations.

@MartinBüttner can we get some of those peanut butter pretzel nuggets as prizes?
 
Oh, and if you go back through the transcript, you'll see I posted it in here, and then when people had difficulty finding a pattern, and I kept getting sequential terms to provide more data, that's when I realized that it would be a good challenge.
 
@quartata what.
 
@quartata Peanut butter muenster sandwiches?
 
7:16 PM
@MartinBüttner for best of PPCG
 
@El'endiaStarman unfortunately, "interesting pattern" isn't the whole deal. remember that weirdly semi-chaotic/semi-regular sequence I found a few weeks ago? the plot was really interesting but I never turned it into a challenge, because the implementation is fairly boring.
 
@MartinBüttner The fractal-like one?
True, it's not the whole thing, but it's a good start!
 
@El'endiaStarman yeah that's true
 
Oh yeah, that one.
 
@MartinBüttner Sorry but I'm gonna pass on writing a challenge for either of them. I know it sounds weird but I don't feel like I know them enough to do it. (Also, I'm just not in the swing of writing challenges lately)
 
7:19 PM
Bingo!
In recreational mathematics, a Harshad number (or Niven number) in a given number base, is an integer that is divisible by the sum of its digits when written in that base. Harshad numbers in base n are also known as n-Harshad (or n-Niven) numbers. Harshad numbers were defined by D. R. Kaprekar, a mathematician from India. The word "Harshad" comes from the Sanskrit harṣa (joy) + da (give), meaning joy-giver. The term “Niven number” arose from a paper delivered by Ivan M. Niven at a conference on number theory in 1977. All integers between zero and n are n-Harshad numbers. == DefinitionEdit == Stated...
 
@Calvin'sHobbies that's fine
 
@CᴏɴᴏʀO'Bʀɪᴇɴ Already have that one typed up ready to sandbox :P
 
@CᴏɴᴏʀO'Bʀɪᴇɴ Also codegolf.stackexchange.com/q/6488/42963
 
perfect totient number might make a decent challenge
 
7:20 PM
@CᴏɴᴏʀO'Bʀɪᴇɴ well, there's also the question whether it's really interesting to golf...
 
Mine was something along the lines of "given a base-10 integer n output all the bases between 2 and 36 where n is a Harshad number" or something like that
would have to dig it back up
 
@CᴏɴᴏʀO'Bʀɪᴇɴ You can use this idea if you want. I wouldn't make it an optimization problem though, just implementing the raking. Like "given the data for the leaf points and rake strokes, output the resulting leaf points".
 
@Calvin'sHobbies You should make a team-based challenge in honor of the teamwork winners... oh wait. :)
 
@Mego Out of curiosity, do you ever see my avatar leave/enter the room?
 
7:22 PM
@quartata still... it's loop/filter + base convert + sum + modulo. it's nothing we haven't done a hundred times and also I don't see any interesting shortcuts.
 
I know, which is why I hadn't sandboxed it yet
 
@MartinBüttner this is the obvious trivial solution for 27. The best I could come up with is this for 25, as long as you are prepared to accept a trailing space
 
(IDK if anyone thought the joke I was trying to make was funny)
 
@PhiNotPi You and Sp will just win again ;)
 
The joke was that you made Red vs. Blue.
 
7:24 PM
Making challenges is getting more and more difficult because that sweet spot of challenge difficulty is getting smaller and smaller because of the influx of newer more active users
 
@Calvin'sHobbies Thanks, but I want to try and make one first :)
^^
 
@quartata Is it that, or is it more that you've run out of your stock of easy good ideas? :P
 
@PhiNotPi My brother is an animator for the company that made Red vs Blue (Roosterteeth)
 
@El'endiaStarman No, I haven't. But easy good ideas are just not interesting enough.
 
@Rainbolt Really? Sweet.
 
7:25 PM
And hard good ideas are too hard.
 
This is promising, but seems already done:
A strobogrammatic number is a number that, given a base and given a set of glyphs, appears the same whether viewed normally or upside down by rotation of 180 degrees. In base 10, a legible set of glyphs can be developed where 0, 1 and 8 are symmetrical around the horizontal axis, and 6 and 9 are the same as each other when rotated 180 degrees (such as the digit characters in ASCII using the font Stylus BT). In such a system, the first few strobogrammatic numbers are: 0, 1, 8, 11, 69, 88, 96, 101, 111, 181, 609, 619, 689, 808, 818, 888, 906, 916, 986, 1001, 1111, 1691, 1881, 1961, 6009, 6119, 6699...
If not, dibs.
 
He works on RWBY
Which I believe is pronounced "Ruby"
 
I've not watched that yet, but I've heard good things.
 
@Rainbolt I actually saw the first season of it.
DAE not get the connection of Red vs Blue challenge with Red vs Blue show?
 
I haven't seen it.
 
7:27 PM
@DigitalTrauma I had 24 without a space: retina.tryitonline.net/…
mbomb found 19, but it's not reusable, because it prints the characters individually instead of creating a string that contains them.
 
Do we have a challenge about Happy Numbers?

Q: Find whether a number is happy or not?

fR0DDYA happy number is defined by the following process. Starting with any positive integer, replace the number by the sum of the squares of its digits, and repeat the process until the number equals 1 (where it will stay), or it loops endlessly in a cycle which does not include 1.

He died
 
Ah, okay.
That's sad but it also means my brother can do some battle scenes. He literally just moved from camera guy to animator.
The credits show the same either way I think
But some of the team animates and some gets the output of the animators and controls the camera while making tiny fixes (clipping issues, etc.).

Monty did Haloid, the animation in RvB seasons 7-11, created RWBY, and did a lot of the battle animation for RWBY

My brother was like "I wanna be an architect." Then I decided to be an architect in high school and he said "I wanna be a computer science major." Then I decided to go for comp sci and he said "Fine I'll be an artist. John will never do that." You think I'm kidding but he actually said he switched because he didn't wanna do what I was doing.
So you can thank me for your next episode or RWBY.
