The Nineteenth Byte

2:54 AM

@Sp3000 Great job on the docs! The page about the new operators was quite helpful.

By the way, do you have any idea why I sometimes "find a maze" when I try to access the tutorial?

Sp3000

Probably because I changed the docs from cjam-docs.readthedocs.org to cjam.readthedocs.org

If you're still accessing the old site

3:30 AM

@Sp3000: Yes, that's it. Kinda strange idea though to show a 404 two or three times and suddenly redirect you after the nth refresh...

@MartinBüttner Thanks for pinging me, I will look at i when I'll have some free time :)

Q: Find primitive semiperfect numbers

11:22 AM

1

Semiperfect numbers A semiperfect/pseudoperfect number is a number equal to the sum of a part or all of its divisor (excluding self). Numbers which are equals to all of their divisors are perfect. Divisors of 6 : 1,2,3 6 = 1+2+3 -> semiperfect (perfect) Divisors of 28 : 1,2,4,7,14 ...

12:20 PM

hi all

hi @MitchSchwartz

Hi @Lembik

@Lembik hi

how things?

the things are being very thing-like today

All the things?

12:34 PM

things are kinda thingsie here

sounds like a thing

Yeah, but I feel something is wrong with my thing

You should ask a thing doctor about that...

Thing doctors wants too much things for taking care of things :/

You should lobby for universal thing care then.

12:42 PM

It may be cheaper in the long run to just get a thingectomy

For a simple case of thingitis? Seems extremely thingy to me.

You have to weigh things up

No thingectomy for me, thanks. I'll just smurf along, and deal with the smurfing outcome later.

It's possible to take things too far.

things just need to stop being so things, you know?

12:47 PM

Didn't mean to sound pushy, I just have a thing about it

You guys are just thingist. Hard to believe thingism like this exists in 2015.

I wonder how many things you could substitute into this conversation and still have it make sense?

If you start smurfing thing with thing, it will smurf !

thing control!

that's what we need

@trichoplax "still" ? :)

Thing is...

12:48 PM

oh for the love of things, what the thing do you mean by that @Geobits?

@trichoplax Thing is everything

bog only knows

All you need is thing

But everything is "all things"

so thing = all things

@Doorknob Spoken like a true antithingite. Deny all the things...

12:49 PM

All things are equal

"one is all, all is one"

all things are equal to the sum of them

Things are getting out of hand

When did this things start?

Things have always been this way

I think things, so things are thinks.

12:51 PM

I don't thing so

I do things, so I am

Maybe there can be too much of a good thing

... you know, has anyone stopped to consider what a sane person would be thinking if one were in the room right now?

:D

@MartinBüttner right on cue...

@Doorknob That's not something to care about :)

12:52 PM

They would probably think all kind of things.

Hi. We're taking about things

@trichoplax huh?

There's no mean in talking if it's not for things !

He made the mistake of thinking you qualify as 'sane'.

@MartinBüttner See Doorknob's post immediately before mine - you appeared just as he said it

12:53 PM

Scroll up. :P

@Geobits common mistake.

well I'm going to go thing some things so... thing you later!

I didn't mean it too seriously. I doubt sanity is really a thing

have thing with that

Have to go to a thing with my thing, things are getting thing.

12:57 PM

How many things would a thingthinger thing if a thingthinger would thing things?

is it an african or a european thingthinger?

Apparently this isn't a new thing. This room goes through stable periods interspersed with thing references.

Much like locusts?

Yes, some sort of chaotic thing

Going to stop now. Things are getting to me

brb

looks like my thing is reported :x

1:35 PM

What is going on here?

Don't worry things have calmed down now

2:41 PM

@trichoplax More than you could say, it's calm as a dead...

It did go very quiet, especially after so much talking at once

The last movement of a dying chat

chat has to sleep sometime

at night?

it's always night somewhere...

2:47 PM

true

but it's always day somewhere too :)

I'll be back to solicit opinions on my canvas zoom once I get it working. I've got as far as making the mouse pointer vanish

also true :)

@trichoplax Wow, impressive ! Got some big conception errors on my controller, I'll have to redo it :'(

@trichoplax Hope it'll be over soon :)

Is that for the summoner war?

Yeah

There's a big conflict between how the controller use movements and the implementation of them

resulting in demon poping from nowhere on the arena... but only for the tests, there's no demon on it....

Fixed it, and everything else falled down :'(

So will rework it

How annoying... :(

2:57 PM

Yeah, the main complexity come from the actions of merging and cloning, which makes me having some big structure to handle them

So now I can learn what was wrong, and redo it !

(by the way, 60kB to the trash >_<)

Ouch

Have to say, not eveything is going the the trash bin, it's already that :)

things like the abstract Summoner, class Demon, enum Direction will not have to change

That's something...

Haha, anyway, my internship end soon, will have more time :)

Why do you explicitly forbid loopholes that are forbidden by default? Isn't that kind of redundant?

I.. don't know

@Rainbolt I've seen a lot of newcomers' answers downvoted into oblivion because they violated a standard loophole. Not all users of this site know about them.

Many of these users never came back.

@Dennis That makes sense

Well, your first statement made sense anyway

The second one is loaded. You are implying that they never came back because they were downvoted into oblivion. That may be the case, but you don't really know that.

I know, I know. Correlation does not imply causation.

If you want to pick nits, the first one is only anecdotal evidence anyway :P

@Vioz- I can't speak for the downvoter, but I'm biased against layered golfs with more than one winning criterion (extra bonuses that change the score). I like to be able to compare like for like

Fair enough

4:57 PM

I think it would be a good challenge with or without nesting, I'd just prefer either to both

@Vioz- I'm not a big fan of multiple bonuses myself. Having two means I have to try to golf 4 different programs and see which one scores best.

The message I got out of that is that I should make a challenge with twenty bonuses and the winner is the one who comes up with a better method than "Try it and see how it scores."

How about "You may remove 20% from your score for each level of nesting you support"

@Rainbolt That would be awesome.

Couldn't you recurse to any level of nesting?

5:00 PM

Exactly

(Not a serious suggestion ;) )

Sorry, my detection circuit broke down earlier today.

Excellent - I'll bear that in mind...

@Vioz- not a good or bad, just a question: Should the 5 strings be distinct (where possible)?

@Vioz- if you stick with the number of combinations bonus/incorporate it into the main challenge, should this just be the product of the numbers of options in each list, or should it count duplicated options as the same, or will the list be guaranteed to be free of duplicates?

@trichoplax Each string doesn't need to be distinct, as long as the code behind is selecting options randomly

@trichoplax It should just be the product of the number of options in each list

I'd recommend making these points explicit in the question (especially that second point)

Alright, I've edited it to make this more clear

5:13 PM

@Vioz- Randomly doesn't mean what you think it means. Selecting always the first option is a form of random selection.

I guess you had a uniform distribution in mind, where each possible sentence has the same probability.

Yeah, that's what I'm trying to say

Do you want to require a uniform distribution, or simply that every combination has a non-zero probability of occurring?

(the later may allow for more imaginative golfs)

I would say the latter.

Have you seen the series of random golfs of the day? Those might have considerations I haven't thought of

I haven't

5:24 PM

Between this and this, we shouldn't really have to explicitly outline every point about randomness any more, should we? Otherwise, what's the point of having them there?

Q: 5318008 - Fun with Calculators

In schools across the world, children type a number into their LCD calculator, turn it upside down and erupt into laughter after creating the word 'Boobies'. Of course, this is the most popular word, but there are many other words which can be produced. All words must be less than 10 letters long...

code-golf

Hope you can forgive me for using your Straight Shooter as a template, Geo. I haven't used Java for so long.

Go for it :D

If anything in it doesn't make sense, that's probably because my KotH entries are always pretty sloppy ;)

Haha, I keep improving the accuracy of the probability distribution and it kept getting worse. Then I realized I had implemented such that the chance of success should have been calculated as 1 - dist, rather than diet.

Brilliance

Hey, I'm just glad you waited until after the bounty ended to beat me :P

5:34 PM

Yeah, I think the overly aggressive bots give it an unfair advantage.

I think it starts playing the bully when it has a decent die advantage over the previous bidder.

I didn't really expect mine to win for very long. It was truly the first thing that popped into my head, and is very simple. There's no changing strategies, etc. I'm glad to see it beaten, if for no other reason that it validates the game more.

When the obvious, simple strategy wins, it's a lot less fun overall.

Yeah, I think the problem was the lack of a smart aggressor to punish the overly conservative bots.

Took me a long while to remember why you did return Attack.ROCK; // faker!

Then I read Doorknob's comment

I doubt that's the only one, just the most obvious :D

If nothing else, I like to post something "feasible" just to get the game rolling.

What a good Samaritan you are.

I posted "Outposts" to Block Building Bot Flocks as a basic strategy to give people something to beat. Beat it they did, but oddly it's still the highest voted

@Rainbolt That implies (to me at least) that there's no secondary agenda.

Well, I guess the following comment cleared that up ;)

Have you ever known me to be subtle? ;)

Yes. For instance, sometimes you have to edit a winky face in after the original post.

Q: Demand for touch support

For interactive questions, how much demand is there to be able to use a purely touchscreen device (no mouse, no physical keyboard). I'm asking thinking of Stack Snippets in questions. Are there any other places where being touch-enabled would make a difference? I'm assuming tick boxes, radio but...

discussion

@Geobits I guessed very few people would want to use their phone for a KotH, but I wonder about tablets. I'm going to go ahead without touch support for now and add it later if people rant.

In my experience, the people who use tablets as their only/main device usually have a keyboard they can use with it.

I was thinking more of people who want to casually watch a KotH run without having to walk across the room to their desktop

Wow this guy with his code reviews... "Code review 63667: Spelling Error Live by the Template die by the Template"

6:38 PM

@trichoplax I frequently post answers to code golf challenges from my phone (one of the advantages of using a concise language), but I don't think KotH would require touch support.

73 files changed. This is giving me a headache

Solution: Leave comments on every single file and reject changes that have nothing to do with the task being solved.

He will get tired of being rejected after a while

@Dennis This is a relief to hear :)

What are some funny ways to ask for a code review?

I am getting really tired of spamming team chat with "CR?" "CR?" "CR?" "CR?" "CR?" "CR?" "CR?"

I don't have Visual Studio Ultimate any longer so I can't send code reviews out like some of my team can

7:23 PM

@Vioz- You can write [0,2][e in c] as 2*(e in c)

in generally, list selection for one of two numbers is shorter done arithmetically

Here's my cheat sheet

Jakube

@Dennis does the output for the no-solution have to be consistent?
For instance can I simply print nothing if there is no integer solution at all and print a integer solution, if there is no natural integer solution.

@xnor for the isomorphs question, would \x00 be an allowed separator ?

@MitchSchwartz yes

ok thanks

any byte that's not a capital letter would be fine

7:40 PM

@Jakube That's OK.

Consistency is not required.

Jakube

Great. I think I have a neat algorithm.

Thanks @xnor :) I got it about as short as it can get without being your exact method (75 bytes)

7:54 PM

sure!

i think there might still be some chars to save though

Oh, there very well might be

just none that are apparent to me right now :P

'#0469@ADOPQRabdegopq$%&8B'.find(x)/20+1 gives the count 0, 1, or 2

Thats clever, saves 3 bytes :)

@Vioz- Also, does the output have to be exactly as in the test cases, i.e., one sentence per line?

Specifically, a trigraph for |

@Dennis Yes.

Huh. I did not know that.

C has a bunch of them

I feel like this is something I should have known before now. It's not particularly useful to me, but I'll keep it in mind.

I'm not quite sure why anyone would find them useful

8:38 PM

I imagine, if you don't have a certain punctuation mark on your keyboard layout, they have a purpose.

I mean, I guess. I don't know what keyboards don't have #^\[]|{}~ these days though.

I wonder if they have some arcane usage in a quine/polyglot.

hi @feersum

Quines/polygots might be the only reasonable usage of them, since C also has digraphs that behave better

So yeah, the whole reason for trigraphs was because of the ISO 646 standard, which isn't really used on modern keyboards.

well, one of the reasons, not the whole reason
