The Nineteenth Byte

Another dumb question that I would know if I spent more time here: Is it preferable for me to put a date after which I will accept an answer, or should I just plan to come back every so often and change the accepted answer

Martin Büttner

found a way for fizzjazzbuzz... not perfect but it works:

0

A: The Smart Person's Mirage

Mathematica In Mathematica you can define and overload functions for very specific parameters (not only by type, but also by arbitrary logical conditions). Let's define a few functions: Fizz[n_, s___] := {n, s} Jazz[n_, s___] := {n, s} Buzz[n_, s___] := {n, s} Fizz[n_ /; Divisible[n, 3], s___] ...

@durron597 the latter

Geobits

I like open-ended personally, but it's not a huge deal either way IMO. Explicitly closing it on a certain date seems like it would discourage answering it after that, though.

Martin Büttner

3:29 PM

just accept after a week or so

and then when you get new answers, check if they beat the currently accepted answer

if someone edits their answer to beat the winner, they'll usually notify you if they care about the checkmark

durron597

Is there a meta question about the subject? I seem to be bad at meta searching today

/me wants to add lots of proposed-faq in meta

Geobits

There are a couple old related ones, but I don't see anything faq-definitive. Searching "accept" gives a few examples.

I thought this would be easy in CJam...

Runer112

it's somewhat simple in cjam

Martin Büttner

@Sp3000 Optimizer has 16

(I had 17)

Runer112

but I'm having trouble with the 0 case

Martin Büttner

it's actually quite tricky though, mainly because of 0

Runer112

yeah

looks like I've got 16

nevermind, 0 is broken agian

if 1 was [[0]], things would be so much easier...

Martin Büttner

4:13 PM

yep

Runer112

I'd be interested to see Optimizer's answer

I think I'm fresh out of ideas

Martin Büttner

do you have 17?

durron597

@MartinBüttner I just copied the style of other deleted answers (don't know if that link will work as it's to a deleted answer)

Martin Büttner

ah right, that's quite old

durron597

Ah. There were several answers like the one I just linked

Martin Büttner

4:21 PM

yeah, if you sort by activity, you'll see that the recent ones are (hopefully) all shortened

durron597

@MartinBüttner I was sorting by votes :-P

Yeah, yeah..

What other sports have the lowest scorer win? I'm sick of using "golf" as a verb.

Martin Büttner

Well darts I guess. Minigolf is a subset of golf though...

What makes you believe that it is +7/-2?

Oh, wrong link lol

Perhaps someone found "@crayzeedude yes, that's sort of the point" to be somewhat rude.

durron597

@Rainbolt shrug

Calvin's Hobbies

@durron597 The downvotes are probably because, besides the scoring, it's not much different than a dozen other Kolmogrov complexity challenges. Just compressing a given string.

Rainbolt

Aww man I had a huge paragraph typed out and Calvin beat me

durron597

I don't care about downvotes, I care about no-comment downvotes

Rainbolt

5:54 PM

@durron597 If someone said your challenge was very similar to this one, would that move you to take some sort of action?

Runer112

it makes an important distinction in that size still matters

Rainbolt

I understand that they are different. I'm asking if a comment would be useful here.

Pretend that I downvoted because Foo. Ok, so what? Is he going to do something about it?

I don't see the point of leaving a comment if we are already past the point where the OP could do something about it.

Calvin's Hobbies

^ Good point

Rainbolt

The OP already knows about the sandbox and chooses not to use it

Someone would have surely mentioned how similar it is

Oh, it was sandboxed

For users who can see deleted: meta.codegolf.stackexchange.com/a/2407/18487

Looks to me like durron already knew some users thought it was awfully similar. So the mixed votes should come as no surprise.

Here was Peter Taylor's warning to him: chat.stackexchange.com/transcript/message/18364760#18364760

You're like +29 on reputation gains for the question. That seems ok to me.

Geobits

@Rainbolt I commented about that when it was posted (I missed it in the sandbox, too). I ended up deleting the comment because it didn't seem productive after that was pointed out.

@durron597 If I don't comment on a downvote, it's because it's either obvious why or it's just not worth the hassle of defending it when people inevitably disagree. They're anonymous for a reason.

Martin Büttner

6:08 PM

@Rainbolt it's not like the OP couldn't learn from constructive criticism for future challenges

Wow. Another downvote

@Rainbolt Well I actually wasn't planning to post the question until @MartinBüttner referred me to the 15 upvotes in the sandbox

ikegami is also the second most annoying user on Board and Card Games

I do not enjoy the experience of asking questions on SO.

Conclusion: PhiNotPi has been trying to figure out what a single function in Perl does for three entire years.

Rainbolt

TeethBones

The date has nothing to do with 10 minute train. I found it on a different site.

I just got an upvote from Physics.SE, are you guys responsible?

@Rainbolt umm... not sure. Probably not too many.

Martin Büttner

1

PhiNotPi

@TeethBones I guess that's interesting.

I can't find anything that says my birthdate anywhere.

Martin Büttner

@Optimizer I think you should go up to N^2 not just 4N

Optimizer

can be done in 29 bytes if 0 based index ..

@MartinBüttner no

Martin Büttner

do you have a proof of that? :P

Optimizer

8:21 PM

yes

in fact, n^2 will fail for N < 4

try it out

(changing the code)

PhiNotPi

Is it ethical to use a lint roller directly on my cat?

Bigtoes

It's only unethical if you don't record it and upload somewhere, right?

Martin Büttner

@Optimizer it only fails for N = 1

Optimizer

luck maybe

Martin Büttner

why luck?

4 == 2^2, 8 < 3^2

that being said, I'd still like to see a proof that a linear upper bound is sufficient

the naive bound is definitely N^2 (or more like N(N+1)/2)

btw, I think you are the first one who actually uses arrays ^^

without arrays, 30 is definitely possible

Optimizer

8:33 PM

Do you have an N which gives wrong result ?

Martin Büttner

do you have a proof that 4N is enough? :P

Optimizer

yes

now . do you have an N ?

:P

Martin Büttner

it'll take some time... I'll need to test pretty large N

so what's the proof?

and why do you even ask for an N if you have a proof that it can't exist?

Optimizer

by your point, if N^2 was the bare minimum, my numbers would have been incorrect starting 4

Martin Büttner

I said it's the maximum

not the minimum

Optimizer

8:35 PM

maximum of what ?

Martin Büttner

you can show very easily that N^2 is the upper bound

there might be a lower upper bound, but I don't have a proof for it

Optimizer

upper bound of what ?

Martin Büttner

of shotgun(N)

well I can show that the upper bound is N(N+1)/2+N-1

but that's still on the order of N^2

Rainbolt

Some guy mispelled "rogue" as in "rouge process" and now everyone internally is misspelling it. That was great until some guy who didn't catch the joke sends it externally to our customer. And here's the kicker... the customer is now spelling it that way too. "I don't see any rouge process"

Bigtoes

Maybe he literally meant a rouge process; the process of applying makeup.

Rainbolt

If I have to apply makeup we're screwed.

Bigtoes

Pun intentional?

No, and I still don't see it

Optimizer

you should rather call makeup, not apply it.

Rainbolt

"Hello, makeup? Yes, I'd like to order a pizza for delivery." Like that?

Martin Büttner

Like spelling 'dammit' correctly -- with two m's -- it's a troll that works best on the most literate.

@MartinBüttner what is the 1524 th number ?

Martin Büttner

3172

Optimizer

correct.

Martin Büttner

it seems like most numbers are less than 3N, but I can't test large enough ranges of large N, because larger numbers would of course be outliers

I'm not saying you're wrong

I'm saying, add a justification for it if you're using a nontrivial bound

Bigtoes

8:47 PM

If sp3000's answer is right, then the 10395th shotgun number is 44405.

that's the first pair outside the 4N bound

Bigtoes

It looks like every multiple of 3465 is.

Martin Büttner

yeah

interestingly, the shotgun numbers aren't multiples of each other though

this is definitely an interesting sequence

Binary lambda calculus

Binary lambda calculus (BLC) is a technique for using the lambda calculus to study Kolmogorov complexity, by working with a standard binary encoding of lambda terms, and a designated universal machine. Binary lambda calculus is a new idea introduced by John Tromp in 2004. == Background == BLC is designed to provide a very simple and elegant concrete definition of descriptional complexity (Kolmogorov complexity). Roughly speaking, the complexity of an object is the length of its shortest description. To make this precise, we take descriptions to be bitstrings, and identify a description method with...
