@undergroundmonorail making hacks for sonic battle, which no one has seem to done before.
There's a palette editor for the Japanese version, but nothing for the American version.

undergroundmonorail

neat

I'm also working on a sprite editor:

Though the only sprites in the game that aren't LZ77 compressed are the battle sprites, which is harder to work with.

Devil Sonic Ornament, complete with hook to hang him on the tree.

Why isn't there a way to close vote an Area51 proposal?

Retrocomputing

Proposed Q&A site for enthusiast users of vintage computers.

Currently in definition.

Retrocomputing, for example

Martin Büttner

@BetaDecay does it affect you negatively that this proposal is open?

Beta Decay

No, just that there was previously a proposal called Retrocomputing which was closed by Robert Cartaino

Chris Jester-Young

@BetaDecay And?

Beta Decay

Oh wait, never mind the previous one overran its 1 year

Chris Jester-Young

Exactly. :-P

Do fictional computers which are supposed to be from the 1970s, but actually are created in 2015 count?

@Geobits is it 73?

@MartinBüttner How have you never joined our Minecraft server? :P (We always need more users - the smallfolk follow their lord.)

Geobits

Probably not. If you have an answer, go for it :P

Optimizer

if its not 73, then i dont

but "probably" - are you also unaware?

More seriously, I answered some questions here with the language TECO, which was definitely an exercise in retrocomputing.

Beta Decay

I guess Sinclair BASIC and BBC BASIC are also acceptable on there

Martin Büttner

@Calvin'sHobbies Because I need that time to play Infinifactory ;)

Optimizer

and numerous other indie games

Beta Decay

Strange...

@BetaDecay I just don't think that optional arguments really are in the spirit of code-golf. I don't really know why, I just think that it shouldn't be allowed. Now that they are both the same length, I removed the optional-arguments version. — Loovjo 3 mins ago

@Optimizer Nah, I know the answer, just don't want to give too many clues in chat :P

Q: We love our weird puzzles, us Brits

In a few British newspapers there is a game known as Hidato. It is somewhat similar to Sudoku, albeit instead of matching into an unchanging format, it's about matching numbers in that one may connect all numbers diagonally, vertically or horizontally (i.e. they must be touching blocks). Here's t...

@Geobits cool

Today is a good day

With a little work I could have posted the task I am working on on main

Martin Büttner

@Rainbolt somehow, this reminded me of an interesting algorithmic problem I encountered in my BSc project, which might make a nice challenge :)

Rainbolt

Mission accomplished

I can't actually say what task I am working on. It would violate my Oath of Silence

Optimizer

won't be the first time

Rainbolt

I've never violated my OoS

Optimizer

dunno :D

seemed like a nice line

Martin Büttner

basically... you're getting a ton of events, each with a timestamp... you want to keep track of how many events happened in the last X minutes. to do so, you count the events in bins (where each bin corresponds to Y seconds, say), which are arranged in a ring buffer of the required size.

Beta Decay

@Rainbolt Who did you pledge this oath to? It's not much of an oath if you do it to yourself ;)

Rainbolt

My employer. I signed my name in fake blood (also known as "ink").

Optimizer

@MartinBüttner challenge is time complexity?

Martin Büttner

for golfing it would probably be more interesting if you required that each event takes at most O(bins) time, so that you can't clear all bins several times if the time since the last bin was several times X minutes.

Beta Decay

@Rainbolt Is your boss Nicholas Cage?

Optimizer

21:02

@MartinBüttner are you enforcing the bin - ring buffer based algorithm?

Martin Büttner

well yes... the challenge would be to produce the most recent set of bins after all events are done.

so it's up to you how you implement the ring buffer, but some sort of binned ring buffer would be necessary (because that's the point of the challenge)

Optimizer

I mean, if its a code-golf, I could have simply used a different simpler algorithm and provided the same output

Martin Büttner

yeah sure

if you can think of one

Optimizer

21:37

ohhhh. you underestimate the brain of llamas.

we have successfully deceived the people of Earth for centuries. Ring buffer is nothing.

Beta Decay

21:52

I guess it's similar to the mice?

Doorknob

@BetaDecay Only the second most intelligent being on Earth.

Beta Decay

You mean third

Optimizer

22:06

yes yes. first llama, second mice and third dolphins. Please don't let a stupid fiction movie fool you otherwise

Martin Büttner

@BetaDecay Fourth.

Doorknob

@BetaDecay No. Humans are third.

Optimizer

@Doorknob Humans are not in top 10.

Doorknob

Well, we're talking about only on Earth.

(Putting aside the fact that Earth is now simply a chain of sausages.)

Optimizer

yes. Only Earth
