The Nineteenth Byte

ATaco

11:00

It's hard to decide which bot would be best, but the 10 to pick from are all round pretty smart.

Geobits

@ais523 I don't really want to write the implementation, but want to know if I'm reading this right: So if I took in an input Java program, for example, I could convert it all to /uxxxx codes for a character set of size 18?

ais523

@Geobits yes, I think that works (Java allows \uxxxx in any context, doesn't it?)

Geobits

Yeah, it gets converted before it compiles iirc.

ais523

of course, your score there will be limited by the fact that a) you're still using 18 characters, and b) you have to write the program in Java :-P

ATaco

I think this is a duplicate, sadly.

Geobits

11:03

Sure, just making sure I read it right, like I said. Of course the output will be huge, too, since it's 6 chars for every 1 input.

ATaco

A: Encode a program with the fewest distinct characters possible,

RProgN, 7 Distinct Characters, Noncompeting RProgN is newer than this question. ' do.Lc Convert the program to 'oooo...' L c 'ooooo...' L c 'oo...' L c . . . do, where each 'oo...' represents the character code in o's, surrounded by apostrifies to make a string out of them. L c then turns them...

Disregard particular answer.

I just grabbed it from my answers...

ais523

I checked for duplicates but didn't find that one

the new challenge is probably better though, the old one's very vague

ATaco

Better normally isn't allowed, but I'm no-one's boss.

ais523

not sure whether to close as duplicate, reverse close as duplicate, or leave both open

ATaco

I've vote to closed the new one.

ais523

11:05

bleh, Lenguage postdates the challenge :-(

but Unary doesn't

let me go exploit that

(actually, Unary is easier than Lenguage…)

ATaco

Some bots that were AUTOMATICALLY GENERATED!

ais523

but in a very vague way

or, hmm, it tried to ban Unary

Geobits

> TacoGeobots

ATaco

Are you judging my bots randomly generated names?

Geobits

Totally

I used to go by Geobot many years ago.

ATaco

11:09

Alright, It's now a 10vs10, This may take like, 10 minutes to load, but hopefully the bots will be hella smat.

Geobits

Maybe even wicked smat

ATaco

Now to just learn C++ so I can submit one of these bad boys.

Geobits

If all you need is a lookup table, you shouldn't need to learn much at all.

ATaco

I should mention, these bots have not been taught to play games any higher than 10 rounds.

As such, their brains cannot get more complex than "9:9"

Geobits

Push that to 20 and you'll probably cover most situations. 10 might be a bit short, but maybe not.

ATaco

11:14

Ooh, Brains are done cooking!

Some more bots, Very smart, Would recommend.

Geobits

I may try something similar, but tomorrow. I've put off sleep long enough.

ATaco

I admire 'RobotGeorge' for only shooting when he has the advantage.

And, good night friendo.

zyabin101

Team Red's ` ` is kinda good.

ais523

I have my own plans for the KotH but I think I'll wait for the hill to get populated first

also I'm not sure I really want to enter in C++

zyabin101

@ATaco Your bot name generator is kinda borked >_>

ATaco

11:18

Itsafeature.

t.name = ""
	for i=1, math.random(0,2) do
		t.name = t.name .. nameStarts[math.random(#nameStarts)]
	end
	for i=1, math.random(0,2) do

zyabin101

ATaco

I may change how the fitness works to give better thinking bots.

I will allow it, But I was keen for Mr but FASTER

ATaco

11:32

Bots now, instead of instantly receiving punish and reward calls after each game, total their wins across all opposing bots. If they win more on average then lose, they receive reward, otherwise, punish. As before there were 10 bots on each team, it was possible to have a 50/50 split, so botsperteam has been lowered to 9.

Of course, now each of the 100000 games these bots get to play for my amusement takes a little longer, but the reward is harder better faster stronger bots.

The new wave of robots has arrived.

zyabin101

Bot would be a nice name for a bot.

RobotRobot could be a good name for a bot.

ATaco

It's amazing these bots did as well as they did, noting their Fitness was broken and set to a permanent 9xGames

Holy cow, I got 50 rep in just 30 minutes in Puzzling

ais523

that's five answer upvotes, which isn't really a lot

rep is very easy to get on SE if you want it

especially if you're willing to use underhanded tactics to do so

(like submitting really easy questions to PPCG)

Kritixi Lithos

It's the fastest (and easiest) rep I ever got

At least I'm closer to Running Ragged now

Falcon

I got duplicate marked on my question, I edit it but the person who marked duplicate didn't remove duplicate tag... and I got downvoted for that... What to do? :(

Q: Tips for posting interesting challenges in ppcg

I'm looking for some interesting ideas which I can apply to code-golf problems which keep track of programmers interest as well as some what tricky to solve. It can be of any language (e.g Python, R etc). The task should rely on algorithm rather than languages. The purpose is to capture programme...

ais523

12:09

you edited an old closed answer into an entirely different question

you probably shouldn't be doing that? it makes it very hard to follow what's going on

(also that's a duplicate of a post on Meta)

Falcon

So, how can I change my question as that other person said its a complete duplicate. So, I have to change it.... I'm sorry I'm new to this so I don't know much...

Should I remove my question?

ais523

yes, better to delete it and post a new one

you should be able to delete your own question

although, with duplicates, sometimes the duplicate question can help people searching for the question

Falcon

but doesn't the duplicate gets downvoted?

ais523

if it gets downvoted, that's normally a sign that people think it's worth deleting

Falcon

Doesn't a duplicate eventually gets deleted by people who got more badges then non-bagers

Isn't this something wrong btw, its actually use of power (kind of)

ais523

12:15

deletions aren't really related to badges, but to reputation

and actually, most deletions are done by Community (which is a bot) on posts that are downvoted, closed, and have no answers

Falcon

Its' written that code golf users with badges can single handedly close questions as duplicates and re-open them

this is not some bot closing or deleting it... right?

ATaco

I do not love C++

No sir

ais523

@Falcon that's possible but it's not the normal reason; the vast majority of closures on PPCG happen as a result of five close votes

and most of the rest happen as the result of moderators "shortcutting" a vote that's inevitably going to go one way or the other

Falcon

Ahaaa.... thanks @ais523.... :)

ATaco

zyabin101

@Qwerp-Derp Not much.

@KritixiLithos Yes! Something did say "Processing"! :D

Qwerp-Derp

Kritixi Lithos

Qwerp-Derp

It's just that I don't know how to put points around a circle

Kritixi Lithos

You can look at this Processing answer of mine to see how I put points around a circle: codegolf.stackexchange.com/a/101902/41805

I used the formula for the Rotation Matrix on wikipedia: m=x*cos(a)-y*sin(a);n=x*sin(a)+y*cos(a);x=m;y=n;

Qwerp-Derp

13:53

oh wait i have to specify an array size?

Kritixi Lithos

float[]array_name = {12,12,45,6,8,...}

Qwerp-Derp

I want to generate an array of factors of a number

So do I just set the default array size to the number?

Kritixi Lithos

What do you mean by that?

Qwerp-Derp

I want to make a function factors(int n) that generates an array of prime factors of that number

How do I initialise the array

Kritixi Lithos

You can use ArrayList. First do the import java.util.ArrayList;

ArrayList a= new ArrayList();a.add(4);println(a.get(0));//4

Qwerp-Derp

14:01

So is the arraylist arbitrary length

Kritixi Lithos

Yes, you can also remove elements

But the contents will be Objects

Qwerp-Derp

Is there any way to turn the arraylist to an int list

I am a complete noob to both Java and Processing

Kritixi Lithos

ArrayList<Integer>a= new ArrayList();

Brb

Qwerp-Derp

So is that now an int list?

Kritixi Lithos

Yes

zyabin101

14:10

I added a. Now there are somewhere over 50 glyphs, including compilations of other glyphs (composite glyphs and duplicate glyphs).

Qwerp-Derp

How can I get the length of an arraylist

Kritixi Lithos

.size()

zyabin101

The font normalisator tried to close the latter as duplicate, but did not know about one specific checkbox... ;)

Kritixi Lithos

This website gives a list of ArrayList functions: tutorialspoint.com/java/java_arraylist_class.htm

@KritixiLithos Or he could just read the Javadocs. docs.oracle.com/javase/8/docs/api/java/util/ArrayList.html

@ais523 Users with gold code-golf badges can also insta-close code-golf challenges as duplicates (i.e. they have a supervote in that one situation).

Gabriel Benamy

my boss changed the password to the server so now I can't sync my local copy of the source code with the server, so I've been waiting for him to come into my office (all of 30 feet) for the past 10 minutes. I'm gonna be as blatant about not doing any work in the meantime as I can until he gets his ass in here and types in the new password for me.

Qwerp-Derp

I think I have most of the code done

Gtg now

Gabriel Benamy

well I got my boss to come in here

and then he walked out without entering the password holy shit

I have no chill today

zyabin101

Pro tip: never use a proprietary company server. :P

Does your company have a GitHub?

Gabriel Benamy

yes but neither my boss nor I has any idea how to use github

and since we're the only developers, that kinda leaves us nowhere

orlp

14:36

@Qwerp-Derp yep

redstarcoder

@GabrielBenamy how do you guys handle merges and history and such? o.o

quartata

Github is not the only Git remote in existence :P

They probably run their own Git or SVN server

Gabriel Benamy

@redstarcoder "handle"

@quartata I wish

we both download local copies of the files to netbeans and upload them as we modify them. since we're both in the same office, we can just yell back and forth when we edit files to make sure we don't override files the other is working on.

redstarcoder

I honstly couldn't even imagine working like that anymore :p

quartata

You could at minimum use co

zyabin101

@redstarcoder no

zyabin101

@quartata Revision Control System? D:

It's too old!

quartata

It's actually not that bad

redstarcoder

Is it better than SVN?

Gabriel Benamy

honestly I don't mind the means for coding -- it makes testing very simple, just upload and test -- but I just wish my boss had included me in the development of the new system before it was almost finished. He has some good ideas but a LOT of this is more complicated than it needs to be. He could have done all of this so much easier rather than hard-coding literally everything.

MetaEd

Then there's this great thing called CVS which layers on top of RCS

zyabin101

zyabin101

@ASCIIThenANSI The caveman war is kinda done, being that an answer is accepted and the last leaderboard update was long ago..

redstarcoder

@GabrielBenamy on Github you can configure it to run the tests for you!

LegionMammal978

@orlp Your username makes much more sense now :P

Gabriel Benamy

@redstarcoder How am I gonna configure github to test if uploading a file visually displays the way we want it to in the system, when the file upload software is licensed for only one IP address?

redstarcoder

I figured you were talking about unit tests lol

quartata

14:53

@MetaEd Unfortunately I'm pretty sure people still use CVS

redstarcoder

Licensed for one IP address though? That sounds rough ..

Gabriel Benamy

@redstarcoder I have a degree in mathematics, not CS, so I'm not even 100% sure what that means

quartata

Unit tests are one of those things professional software engineers use as excuses for artificially extending compile times

2

El'endia Starman

@GabrielBenamy Unit tests test how the system as a whole functions. You use them when you have two separate components that interact, so you want to be sure that the interaction works and that both components interact as expected.

MetaEd

@quartata I was thinking of using a photocopier and optical character recognition. Creates just the right amount of trepidation about actually going back to a previous version.

quartata

14:55

@MetaEd ahahahahahaha

redstarcoder

@GabrielBenamy Usually refers to the standard run of tests to ensure all the code is working. Usually you want your tests to run over all the code, so you don't worry about one minor bug breaking your new function, or your new code introducing said minor bug.

quartata

@El'endiaStarman That sounds more like integration tests

for any kind of automatic test

El'endia Starman

My workplace separates tests into unit and functional, where the latter is for testing specific functions.

quartata

Maybe we have different definitions because the latter is what I would call unit haha

redstarcoder

Wikipedia says In computer programming, unit testing is a software testing method by which individual units of source code, sets of one or more computer program modules together with associated control data, usage procedures, and operating procedures, are tested to determine whether they are fit for use.

So we're all right?

Gabriel Benamy

Well people have been demanding the feature be optional for so long it's surprising that there's still just nothing at all you can do

orlp

@flawr for codegolf it's somewhat ridiculous yes

but consider the wider stackexchange network

if suddenly a bunch of useful information disappeared because someone decided they wanted it gone that'd be a bad thing

and once you post information on stackexchange it's not really 'yours' anymore, it's the community's

flawr

@orlp But it is content they have written themselves

orlp

@flawr and subsequently released under CC-BY-SA by posting on stackexchange

redstarcoder

I actually like that people can't take their content away. There was a whole repo I lost once because a developer dissappeared and I just assumed it'd always be on the net.

flawr

15:38

That means if someone else wants to copy it they can, but it doesn't prevent you from deleting stuff

orlp

@flawr from the point of the community there is no difference between someone vandalizing other people's posts or their own

so the community doesn't accept it when someone vandalizes their own posts

really, once you post an answer for a question that is knowledge kept by the community

El'endia Starman

The way I see it, Stack Exchange is all about collecting and preserving useful information. Self-vandalization runs counter to that, so measures are taken to prevent that.

orlp

the fact that your name is on the bottom right of the post is attribution

not ownership

@flawr if you specifically ask stackexchange staff to delete your account they still keep your posts, but just put it under 'community' or some anonymous thing, I don't exactly know

your account will be deleted, but your content will still be there for the community

that being said, all these rules aren't exactly the best for codegolf as they don't really apply

but they're stackexchange wide
