... learn a golfing language

Geobits

Just go for it! My first few answers (to golfs, at least) were downright terrible, but people helped me out in the comments and gave me tips, etc. It was very welcoming.

The same experience is less likely to happen if you post a bad question.

Yodle

@Geobits Same here, people seem really open to helping newcomers with formatting and whatnot.

Poke

can't a guy just be a lurker in peace

Alex A.

no

Poke

rudeeee

Geobits

20:01

@Poke Sure, but not if he wants rep for it :P

Poke

Well I thankfully now have all the rep I need

Yodle

I got 111, nobody ruin it

TùxCräftîñg

brb downvoting

Geobits

But... you can't get 1111 if nobody ruins 111.

TùxCräftîñg

wow my keyboard and my mouse went mad

Geobits

20:03

Rabies?

confusedandamused

@Geobits Do you use a golfing langauge?

Geobits

@confusedandamused Not unless Java counts. (it doesn't)

TùxCräftîñg

i generally use only the golfing languages i created becuz jelly links are weird

Geobits

I have a couple answers in a couple other languages, but I don't think any of them are "golfing" languages.

TùxCräftîñg

and adam outgolf me by 1e6 bytes when i post an APL answer ._.

Geobits

20:05

I have an APL answer, but only because I was cracking a cops/robbers entry that used it.

El'endia Starman

@NathanMerrill I saw them, actually. Interesting stuff.

What if you tried doing the analysis on data obtained solely from your own messages?

confusedandamused

@Geobits I only really use C# JS and Python at work (mostly C#)

Geobits

All of them are used here, so no worries. C# probably less than the others, but it's not rare or anything.

TùxCräftîñg

you can use any language here if the version used is older than the challenge

Geobits

I'd recommend using C# so I can beat you with Java from time to time, though. It's very rare that it beats python or js ;)

TùxCräftîñg

20:09

ಠ_ಠ

Alex A.

@TùxCräftîñg You can use a newer version, it just makes the answer ineligible for winning.

TùxCräftîñg

ye

DLosc

I typically golf in Pip (golfing language I created), Python, or QBasic. I pick whichever one seems like it will be most fun for the given challenge.

TùxCräftîñg

> QBasic

Geobits

I keep meaning to do some QBasic golfs, but somebody usually beats me to it.

Nathan Merrill

20:10

@MartinEnder can you CW and FAQ this ?

zyabin101

Boxes on top that pop up after load are annoying. I mistapped a few times.

confusedandamused

I just find code golf more interesting than "normal" (like project Euler) problems

DLosc

@Geobits I'm sure I don't know whom you mean. In the last two months, there have been 10 QBasic answers from 6 different users. ~_~

Alex A.

@NathanMerrill Done

Nathan Merrill

thanks!

Geobits

20:13

@DLosc Well, I didn't say I was particularly persistent about it :P

TùxCräftîñg

but CBM BASIC is better than QBasic.

Geobits

No BASIC is better than QBasic. Either that or it's the nostalgia speaking.

TùxCräftîñg

ಠ_ಠ CBM BASIC iz teh best BASIC

DLosc

@TùxCräftîñg I golf in QBasic for the nostalgia; I never learned CBM BASIC; ergo (for me) QBasic is better. ;)

zyabin101

@NathanMerrill Thanks for making that question a smattering and a dupe-like of many normal questions.

Alex A.

20:15

?

It's a FAQ

flawr

@AlexA. is here!

Alex A.

Indeed. Greetings!

El'endia Starman

flawr

welcome back!

zyabin101

@AlexA. It's not a faq without answers.

El'endia Starman

20:16

X axis is words, Y axis is chars. All the different pairings from the last 6 months.

flawr

@El'endiaStarman -1, not an OEIS

Alex A.

@zyabin101 It links to relevant answers in the question itself

Geobits

@TùxCräftîñg If ever there was a better BASIC than QBasic (there isn't), it would be GW-BASIC.

confusedandamused

@Geobits I found this useful meta.codegolf.stackexchange.com/questions/7261/…

Alex A.

@flawr Thanks :)

TùxCräftîñg

20:17

@Geobits from krosoft so itz bad

Nathan Merrill

@zyabin101 its conceptually similar to this

zyabin101

Also, I can't edit tags anymore just to ignore that question because Alex A. inserted the mod tag faq in it.

Thanks.

El'endia Starman

@NathanMerrill: There may not be much of a linear correlation, but there's definitely some sort of correlation.

Geobits

@zyabin101 Is there anything that will please you here? You basically begged for the question to be posted, and now you are mad you can't ignore it?

zyabin101

I may want to quit Programming Puzzles & Code Golf Meta fully including writing in the Sandbox due to the junk.

Adnan

20:19

ლ(-__-ლ)

Nathan Merrill

@El'endiaStarman you can't do character vs words. You have to do average word length

zyabin101

help

how do I edit tags in a faq question

Alex A.

What are you trying to edit in?

El'endia Starman

@NathanMerrill But....it's so cool!

Nathan Merrill

you're right, but you're finding correlations that longer messages happen to have more words

surprise!

flawr

20:20

@El'endiaStarman The top part definitely has a snowman correlation

zyabin101

@AlexA. already did thx

El'endia Starman

@NathanMerrill It's still interesting how it's bunching up.

flawr

@NathanMerrill A friend of mine once found a quite good correlation between radius and diameters of circles.

Nathan Merrill

@El'endiaStarman I still think you'll see it. You're basically rotating the graph 45 degrees

El'endia Starman

@NathanMerrill So you're saying, x = words, y = chars/words?

Alex A.

20:21

@El'endiaStarman Could use a Box-Cox transformation, find the optimal λ such that the relationship of transformed variables is approximately linear

Nathan Merrill

yes

Rohan Jhunjhunwala

@Dennis thank you

zyabin101

Now, I added tags [scoring code-golf answers] to ignoreds and hid questions in these tags altogether.

Alex A.

Why?

zyabin101

Because of that junk, of course.

Also, I enabled adverts back.

Alex A.

20:24

What junk is that?

zyabin101

Does that do something?

Geobits

@zyabin101 So, what you're saying is the last couple hours of you asking for these to be grouped up was just a massive troll?

zyabin101

I chose the wrong user.

Geobits

Wow

zyabin101

To write the question, I chose the wrong user.

Geobits

20:26

Congratulations. You just insulted the one person who volunteered to help you out. Good luck on that happening next time.

16

zyabin101

Sorry.

I should be the one who should have written it.

Alex A.

Don't apologize to us, apologize to Nathan for effectively wasting his time. (Though I for one greatly appreciate the post he made.)

Q: How to count bytes FAQ

We've got a lot of questions asking how to count the bytes in different situations. This question is here to put them all in one spot. General questions How to count flags How to count "interactive" answers How to count REPLs How to count multiple files How to count lambdas How to count newlin...

Poke

@NewMetaPosts How appropriate

NewMetaPosts has a way with timing

it's uncanny

Rainbolt

Did you know that counting bites can help you lose weight?

TùxCräftîñg

20:30

langton ant rule RU*nL have a 2-number counter in base n+1 in near every pattern

Geobits

Counting bytes can cause weight loss too if you forget to eat.

Poke

@Rainbolt Haha. given to us by the same website that brings us "8 reasons you have an itchy butt"

TimmyD

If you're digitized like in Tron then counting bytes is the only way to lose weight.

Geobits

I've heard mounting bikes helps, too.

TimmyD

What about mounting mountain bikes?

El'endia Starman

20:33

Or bikers?

Poke

@flawr I almost stumbled on that once but I'm pretty sure it was just a rounding error

Geobits

I'm not sure if I should groan or give a round of applause.

PhiNotPi

@El'endiaStarman I'm wondering if the y-axis is slightly off on your diagram above. For example, there's a big horizontal line that's above 500 characters, but I expect it to be exactly 500 characters (because that's the normal chat character limit).

Nathan Merrill

@Poke lol, this took me a bit

Poke

:D

El'endia Starman

20:36

@PhiNotPi I have noticed tick marks being slightly off before for time, so that could possibly be the reason for that discrepancy too.

Geobits

@PhiNotPi IIRC the messages are stored as html, so things like markdown would put many just over the limit.

Poke

I saw my opportunity for a great pun

It shall not be squandered

El'endia Starman

@Geobits Not by that much though. The line seems to be around 550.

Geobits

Oh, I didn't know it was that high :/

Nathan Merrill

oh, a real mini chat challenge: get as many characters into the html as you can

El'endia Starman

20:39

@NathanMerrill Alas, no, not really.

Geobits

The character limit for multi-line messages would be quite spammy :P

El'endia Starman

@Geobits TNBDE actually doesn't store huge messages accurately since the transcript shows a "load more text" option, which the transcript scraper doesn't click.

Nathan Merrill

@El'endiaStarman there's an interesting "second line"

Geobits

Oh, I meant that in relation to Nathan's [cmc-proposed]

Nathan Merrill

on larger messsages

TimmyD

20:41

@Fatalize Dang, then I guess I'm out. Fastest I can get input 204 to run on PowerShell is ~3 minutes, even after trying several different algorithms (including Fisher-Yates to come up with permutations rather than trial division).

PhiNotPi

Yeah, I wonder what's up with gap in 600-800 character messages.

Fatalize

@TimmyD Really? Is Powershell that slow?

TimmyD

There aren't any built-ins for primality checking, factorization, or array permutations, so everything is interpreted at runtime.

Nathan Merrill

reminder: don't code your next cracker in Powershell

Fatalize

So the problem is that you can't implement a decently efficient prime factorization algorithm in not-too-many bytes?

TùxCräftîñg

20:44

solution: dont use powershell

Geobits

That's like telling someone with a penguin avatar not to use linux.

Nathan Merrill

lol

TimmyD

Fun fact: TuxCrafting uses Windows.

TùxCräftîñg

but i have a linux machine so

Rainbolt

I don't play Minecraft

zyabin101

Did anyone ever check if their computer is stable?

DLosc

Odd fact of the day: three of my top five answers are on questions that have since been closed. :^\

El'endia Starman

@feersum Their subsequent "*actually" didn't help. :P

TùxCräftîñg

you know when a CA have too many states when arriving at a basic structure take 10 mn in speed 8^6 ._.

@zyabin101 I did just now. After tilting the box slightly, it returned to an upright position.

Nathan Merrill

@zyabin101 the power port is messed on my laptop, so many times, I end up putting the cord beneath my laptop (to get it in the right position), making it unstable. Funny enough, its stable right now

zyabin101

Not case tilt stability, full PC stability.

My computer holds a horse, so yes

zyabin101

CMC for users with smartphones: run Memtest86. (One test pass is enough.) :P

TùxCräftîñg

20:49

ಠ_ಠ never itz propietary

TimmyD

@Fatalize No, that's pretty easy. The problem is I either need to iterate through every possible number up to (divisors sorted and joined together) or create permutations of the divisors.

Geobits

Marky is my stability test. He can runs all cores at >90% for days on end, with well over 8GB of RAM used just for him. Nothing's exploded yet.

Fatalize

halp I still have 26 days of vacation to take before the end of the year, this is too many

TùxCräftîñg

zyabin101

20:51

@Geobits He tests the CPU.

Geobits

He tests everything I actually need to test for. My computer runs fine, and I don't see a need to torture it for no reason except the lulz.

zyabin101

@TùxCräftîñg Then find an Ubuntu Server ISO, and boot from it and choose the Test memory option in the prompt.

Rainbolt

@Fatalize How many of those 26 roll over to next year?

zyabin101

But you have to have a smartphone for the CMC tho, so...

TùxCräftîñg

wikipedia say it's proprieatary and it also say it's GPL licensed

total mindfuck

Fatalize

20:54

@Rainbolt 10 at most I think, but then I would have even more days to take next year ._.

TùxCräftîñg

'nniiigggghhhhhtttttt

TimmyD

@Fatalize Solution -- take off the entire month of November.

zyabin101

@TùxCräftîñg Say in the talk page: "The infobox says it's proprietary, but the text of the article says it's GPL licensed."

Fatalize

@TimmyD at this points I'm probably gonna take 3 weeks in December, so you're not too far off

Poke

@Fatalize take off thanksgiving week and christmas-new years

that's like 8 days or something

Fatalize

20:56

@Poke I mean, I don't know if you know that but... we don't give a damn about thanksgiving outside the US

Poke

Did not remember that you were outside the US

noice

find some holidays and take those weeks off

that's what i do

Fatalize

I said I have 26 days remaining of paid vacation, so you could have easily guessed that I'm not :p

Geobits

sick burn

Poke

Why is that? based on the number of days?

Geobits

Though I had 88 days at one point ;)

Poke

20:57

I suppose I only get like ~15/year

but that should grow over time so we'll see

Fatalize

that's like... nothing

Poke

3 weeks is a lot of time

Fatalize

one week for christmas two in the summer

that's really not much

Poke

i will sometimes take a monday or friday off when we have a friday or monday off to get a nice 4 day weekend

other than that i don't really take days off

i also get like 5 sick days which is explicitly separated

Fatalize

lol

sick days should be infinite

Poke

21:00

i mean if i'm really sick i can talk to my manager or whatever

and we'll figure it out

but if you start missing too many working days i can understand people getting upset

especially if you stop meeting your deadlines because of it

(no longer speaking directly about my job)

confusedandamused

So when using c# is it better to check for nulls on your own when calling .toString() or would it be better practice (but maybe slower?) to use Convert.ToString()?

Geobits

What does Convert.toString() give if you feed it a null?

Poke

@confusedandamused I think I need a little more context here but in general if it's something you can prevent yourself I'd prefer that over using exception handling

although for codegolf pick whatever is shorter

Nathan Merrill

oh, that's reminds me. I recently found Objects.equals() in java

which does null checks on both objects

confusedandamused

@Geobits An empty string where as .toString would return a NullReferenceException

Nathan Merrill

21:03

quite convenient

feersum

@NathanMerrill Really, on the first object?

Nathan Merrill

its a static method

Poke

@NathanMerrill java8?

Nathan Merrill

not the generic one you find on all classes

feersum

Oh, there are two Object.equals()?

Geobits

21:05

Objects.equals(a,b), not Object.equals(a), right?

Maltysen

@NathanMerrill there's another one?

Nathan Merrill

my bad. Its Objects

Poke

ah

Rainbolt

@Geobits I would avoid having to know the answer to that question and just use myObj?.ToString() ?? string.Empty

Or making the reader of my code know the answer

Geobits

@Rainbolt Personally, I usually check myself. I was curious if it would return a null string rather than empty, which would make using it to avoid null-checking silly.

I was just thinking:
Many governments in general are controlled by public pressure.
Public pressure is mostly controlled by the media.
I'd be thoroughly surprised if the media wasn't controlled (indirectly) by politicians.
So...

confusedandamused

@Poke I was just reading about dealing with strings and sometimes it's nice to have a better error message when working with writing XML or something rather than getting "Object reference not set to an instance of an object"

Poke

You can set whatever message you want if you do the check yourself ;)

i gotta go. ta ta for now

Nathan Merrill

@ΛεγίωνΜάμμαλϠΟΗʹ I don't think the media is "controlled" as much as "filtered" by politicians. Media still needs to sell

zyabin101

Ohh, a few mins ago, in Space Trader, I was assigned a quest to deliver disease recover thingies to Japori.

Geobits

This part?

ΛεγίωνΜάμμαλϠΟΗʹ

The politicians certainly aren't controlled by the governments

Geobits

Without that one, the whole "triangle" thing you're going for doesn't make much sense imo.

ΛεγίωνΜάμμαλϠΟΗʹ

It's not really a triangle

Geobits

Oh, so you're saying politicians control government? I thought that was clear.

Since they effectively are the government.

ΛεγίωνΜάμμαλϠΟΗʹ

21:11

@Geobits Not if they're U.S. politicians

Geobits

Which politicians aren't (or were not, or trying to be) part of the government?

ΛεγίωνΜάμμαλϠΟΗʹ

Geobits

Oh, I see what you're saying.

PhiNotPi

@NathanMerrill I think I'm going to revisit your Topping the Charts KOTH.

Nathan Merrill

that said, politicians absolutely try to show a particular story in a particular way. That said, it backfires when the "presented version" is less interesting than the real one

@NathanMerrill I don't think the "How to count flags" post is relevant. the de facto standard is part of the "How to count 'interactive' answers" post.

Computer scientists, man

Martin Ender

@NathanMerrill will do

Nathan Merrill

you can totally make proofs about your code. They are just prone to the same problems with proofs in real life

aka, human error

Martin Ender

looks good for now but this list definitely tells me we need newer, more comprehensive and more to-the-point posts for some of these

e.g. the way the flag counting rules are buried has been annoying me for a while

Nathan Merrill

21:33

yeah

uoɥʇʎPʎzɐɹC

I'm making a list of reasons why it won't work

Nathan Merrill

maybe the answer just needs an uplift?

uoɥʇʎPʎzɐɹC

If we can hack-proof code, we can bug-proof code!

Hacking is just unwanted behavior defined by arbitrary human criteria

Bugs are unwanted behavior.

El'endia Starman

@uoɥʇʎPʎzɐɹC ....yes, of course.

uoɥʇʎPʎzɐɹC

@El'endiaStarman no more unit tests!

and a whloe ton of math!

Nathan Merrill

21:36

this is why hack-proof code is under the same umbrella as proofs

uoɥʇʎPʎzɐɹC

Who wants that?

Nathan Merrill

if you can write a proof without making a mistake, then you can write bug-free code

El'endia Starman

That's how formal verification was envisioned a couple decades ago. Bugs just weren't a big enough problem to go to the effort of formally verifying your code.

@uoɥʇʎPʎzɐɹC: I think you need to read more about formal verification.

uoɥʇʎPʎzɐɹC

@El'endiaStarman if we use the langauge of math because it is precise and exact...

..programming languages are unambiguous

no translation needed!

So then HACMS should just be a really good linter.

El'endia Starman

@uoɥʇʎPʎzɐɹC ....yeah, pretty much.

uoɥʇʎPʎzɐɹC

21:42

@El'endiaStarman so now apparently we have a perfect linter for hacking

(to logic errors)

nohacks main.js
uglifyjs main.js > build/main.min.js

Nathan Merrill

this is why I hate PHP. The amount of standard "interpretedness" is really hard to do any verification about

uoɥʇʎPʎzɐɹC

this might be in my build script soon

Nathan Merrill

$a = "someProp";

@Sherlock9 Happy birthday!

It's probably already tomorrow over there, so i'm a little late

Luis Mendo

@JonathanAllan No need to do that, really :-P

Nathan Merrill

@mınxomaτ you mentioned that scanning the internet makes ISPs mad. is there a story there?

mınxomaτ

Many. Maybe I'll make a post some time about that.

Jonathan Allan

@LuisMendo huh?

Q: Is this string prime?

A string is called a "prime string" if it can't be written as a concatenation of more than one of the same string. Your task is to write a program that, given a sequence of letters of length N (5 < N < 100), determines if it is prime or not. Examples Input: AAA Output: not prime Input: FD...

@JonathanAllan No need to golf down your answer below 67 bytes ;-)

@LuisMendo oh I see :D

@LuisMendo as I was making it I was sure it would be, and then it got all messy fitting in all the last bits

...probably cos I'm no golfing genius

Luis Mendo

It seems to me you are learning fast!

Jonathan Allan

thanks

@NathanMerrill That totally HAD to get a regex answer. I didn't even TRY anything else :-)

@TonHospel so you are going to start learning Retina then?

Ton Hospel

Who knows. I usually look at the retina answers and wish perl had some of these features

e.g. /^(.+)+$/ with forced backtracking would be great for the recent partition a number question, except that perl has no sane way to extract how the () matched

Martin Ender

@TonHospel I'm flattered :D

Ton Hospel

@MartinEnder Mainly for golfing to be sure. For actual work it seems a bit...esotoric :-)

Martin Ender

That's true. Although I do occasionally use it for nontrivial string transformations outside of golfing.

Although I think if Retina ever reaches a state where I'm happy with its feature-set I'd like to make a more usable and readable sister language.

@MartinEnder this will never happen

Since there are very few perl opponents here I often look at other languages as a measure to gauge my solution, something like : I should get 20% below python, 10% below ruby and about equal on retina, except for the cases where retina totally blows me out of the water

Nathan Merrill

@TonHospel do you perl for work?

Ton Hospel

@NathanMerrill Yes. Mostly around networking

@flawr A lord peg

Ton Hospel

Mmm, the decanting problem also has a nice pure regex solution of about 50 bytes in perl

Should be a good fit for Retina

Mm, no, it needs some extra logic. Bummer
