Are the 100 rounds in a game always between the same 2 players? Who will judge the competition? Will you be running the scorer for every submission on your own pc?

Juan

Apr 28, 2011 22:19

What I found unclear is the competition itself

Juan

Apr 28, 2011 22:18

@dmckee It looks interesting. The rules, text and interface look good.

Juan

Mar 9, 2011 05:25

@dmckee I thought of doing a PRNG question a few days ago, and I thought it was a bit limited. It won't have many takers.

Juan

Mar 1, 2011 02:36

@Joey Yeah, I fear people might give up on the problem too soon, so it'd be better if the information was handy

Juan

Mar 1, 2011 02:23

Please let me know what you think about it

Q: Implement Shamir's Secret Sharing reconstruction

Shamir's secret sharing scheme is a simple way of protecting a secret by splitting it into several parts needed to reconstruct it. Your task is to implement Shamir's Secret Sharing reconstruction over the Finite Field defined by the prime 1928049029. If you have any doubts about what this means,...

Juan

Mar 1, 2011 02:23

And there it goes

Juan

Feb 28, 2011 23:53

I can't quite figure out the operations on the finite field.

Juan

Feb 28, 2011 23:52

Well, it appears implementing Shamir's Secret sharing is not simple at all

Juan

Feb 27, 2011 08:04

Well, I guess I need to investigate further before writing up a problem. Thanks @ChrisJesterYoung and @Nabb :)

Juan

Feb 27, 2011 07:56

@Nabb that's true. The field would have to be defined, and the input constrained to said field.

Juan

Feb 27, 2011 07:42

@ChrisJesterYoung Maybe I can get two problems out of that, one for creating the parts, and an other for recovering the secret.

Juan

Feb 27, 2011 07:35

@ChrisJesterYoung Well, that gives what I wanted to do a name :P

Juan

Feb 27, 2011 07:22

Maybe, given a set of points, calculate the value of that polynomial for a given x.

Juan

Feb 27, 2011 07:21

Polynomial interpolation

In numerical analysis, polynomial interpolation is the interpolation of a given data set by a polynomial: given some points, find a polynomial which goes exactly through these points. Applications Polynomials can be used to approximate more complicated curves, for example, the shapes of letters in typography, given a few points. A relevant application is the evaluation of the natural logarithm and trigonometric functions: pick a few known data points, create a lookup table, and interpolate between those data points. This results in significantly faster computations. Polynomial interpola...

Juan

Feb 27, 2011 07:21

I'm thinking of posting a question related to polynomial interpolations.

Yours still in the 1000+?

Juan

Apr 28, 2011 01:43

I haven't read that one yet. I wanted to start without any influence. Once I have mine down to ~400 I'll post it and check the other one out.

Juan

Apr 28, 2011 01:34

well, I have 450 chars for the nested boxes

Juan

Apr 28, 2011 01:29

I just looked up what Piet is, and I agree, he's sick. You need help.

Juan

Apr 28, 2011 00:35

congratz on passing the tests btw

Juan

Apr 28, 2011 00:35

wow

Juan

Apr 27, 2011 23:58

@Casey sadly, python. I'm hoping that after crafting the first solution, I'll gain some insight to work out something crazy like those 200

Juan

Apr 27, 2011 23:47

@Casey yeah, 200 chars is way too little compared to what I'm getting

Juan

Apr 27, 2011 21:22

I was hoping something like this popped up

Juan

Apr 27, 2011 21:22

@Joey you really took your time to write that question! And it looks like an interesting problem too

Juan

Q: Uptime Bash Penis

Write a bash expression which parses uptime and generates a penis with a length of the number of days: $ uptime 23:01 up 34 days, 7:30, 5 users, load averages: 0.23 0.27 0.24 $ uptime|<command> 8==================================D (34 days = 34 equal signs) Shortest answer wins.

Mar 12, 2011 22:17

I'm not sure how I feel about this question, I mean, it doesn't bother me, but it feels sort of out of place.

Juan

Mar 12, 2011 00:44

@Joey on the abbacus one? Nice! I'm gonna try that one tomorrow, it seems fun

Juan

Mar 11, 2011 23:49

@JB lol, I remember seeing his answers in the early days. Nothing recent though

Juan

Mar 11, 2011 23:45

Or maybe, we don't understand what you meant by that :P

Juan

Mar 11, 2011 23:25

@Joey but who would moderate that? It's unreasonable to ask of the mods to check every question before hand. They'd be expected to help improve the question until it's approved

Juan

Mar 9, 2011 22:36

@JB it got tweeted by jeff atwood

Juan

Mar 2, 2011 01:48

So then the number is definitly is smaller

Juan

Mar 2, 2011 01:34

Not many new problems the last few days, it's quite boring :P

Juan

Feb 28, 2011 22:37

@Dogbert I was planning on giving it a shot in a few days.

Juan

Feb 27, 2011 23:16

@eBusiness Well, for some entries is really hard to validate. Perl, golfscript and J make it a nightmare.

Juan

Feb 25, 2011 04:37

@ChrisJesterYoung user id 3? You got here fast :P

Juan

Feb 25, 2011 04:36

@ChrisJesterYoung how many more days on code golf to get it for you?

Juan

Feb 25, 2011 04:34

Almost there! :P I gave up on that one when I was half way through and forgot for a day

Juan

Feb 25, 2011 04:32

@ChrisJesterYoung Ah, well, couldn't be happier then! lol

Juan

Feb 25, 2011 04:31

@ChrisJesterYoung Well it's a reward for being incredily additcted to the site

Juan

Feb 25, 2011 04:30

I just got it, feels kinda.... wrong?

Juan

Feb 22, 2011 05:20

@GeorgeEdison that and the namespace separator. Otherwise a pretty ok language :P

Juan

Feb 18, 2011 02:10

@Nemo157 huh, I'd like to see how it handles self-modifying code (If it does support that)

Juan

Feb 18, 2011 02:04

@Nemo157 is there an interpreter for that?

Juan

Feb 18, 2011 02:02

Wow, the MD5 pseudocode is really long. I can see how my sunday afternoon is gonna be.

Juan

Feb 18, 2011 01:58

I think he's the only one that kept the same rep-gain momentum after the site went public beta.

Juan

Feb 18, 2011 01:55

@Nemo157 that sucks! I just checked and I'm about to drift to the third column, really gotta work on my rep
