Well holy crap. Delta's unaccompanied minor fee jumped from $50 to$150 in the last year.

Is Delta a travel service?

An airline.

Ah OK.

I've used them before because they had decent fares and the UA fee was low.
Kid's coming back on the 10th :D

I didn't realise such fees existed - I thought it was just either allowed or not.

12:02 AM
There's a fee for everything ;)
To be fair, this fee actually makes sense in a way, since it directly increases the workload of the flight attendants.

Happy reunion! That'll be $150 I just didn't expect it to triple in a year's time. Yeah that makes sense. Adults are always so much better behaved. @MartinBüttner 2 bytes shorter but a lot slower: ^(1+)!.*\1{90000}! instead of ^(1+)\W+\1{90000}1+! Well, it's more that they have to actually accompany him to/from the gate, sit with them if they get scared (not a worry with mine, he loves it), and if anything happens to the flight (delay, etc), they handle the rebooking, hotel, etc as part of the service. 12:05 AM That actually sounds reasonable then. Yea, I don't really object to the existence of a fee. But damn :P @Geobits That sounds exciting! How old is your kid? He's eight, and done it a few times now. He loves flying :) @Maltysen I got it mostly working, but it encodes spaces as pluses, which screws up and programs that have spaces in them. @phase why is it being encoded? you used$.post()

12:15 AM
when I encoded it to the URI, and back again the the code

Man, I would be terrified of flying alone at 8! It's good that he likes it. How often does he fly?

@phase yeah your server needs to decode it
are you using a framework?

Twice a year, at the beginning and end of summer.

if not urllib should have function for this kind of stuff

@Maltysen I'm encoding it with jQuery and decoding it with jQuery

12:18 AM
Some kind of summer camp?

Nah, goes out to stay with his mom over the summer.

@phase wait what?
are you using js for the server

The first time I flew I was 22

@Maltysen No, but I'm transferring the data through the URL
I encode it with var code = $.param({code:$('#code').val(), input: $('#input').val()}); then window.location.pathname = "/link/" + code; great 12:20 AM Ah, I understand. Whatever works works! now, your server has to have a handler /link/ get("/link/:code", (req, res) -> {return readFile("res/link.html");}); whatttt no thats not the point of a permalink your permalink is just to fill in the textboxes it does that after it goes to the link page your js should not be invloved in retrieving you server should fill it in like on the /link/ handler return fill_in(index.html, query params) yup OH WAIT DUHHH ohhh one sec.... you don't need /link/ just do doc.loc='?'+parms in js and your java code u have now should work no wait no move that code into get it sohuldn't be post 12:41 AM > Sites are defined much more by their membership than by their stated topic; I dare anyone reading this to compose a one-sentence summary of Server Fault's scope that doesn't boil down to, "stuff sysadmins aren't bored with yet". Interesting wording, but I can't deny it's pretty much true. 2 @MartinBüttner actually you would need ^(1+)!.*\1{90000}1! because of the D=300 case, so you would only save 1 byte 0 This is a CG based on the previous code-challenge Holy Hole In A Donut, Batman!, which attributes scores to each character in a string, including whitespace and newlines.

Two thumbs up. Hmm... How hard is it to describe a problem in English with fewer characters than it takes to solve in CJam? @BrainSteel "Print the Gettysburg Address." Ah, good point. I did not consider proper nouns :P I suppose "Solve the halting problem" is sufficient, too.

you know if all you want is to get Hi then you are in trouble

@Lembik umm.. why ?

@Optimizer :) Hi == High == ....

7:38 AM

and general weak word play

@trichoplax stop it
why you do this to me ?
every single time it changes, my eyes automatically point there.

@Optimizer it was my first word here in weeks too - does that count for anything?

@grc makes it even worse that you broke your silence and first thing you say is Hi to me :P
It should totally have been to Lembik!

and it's too late to edit :(

@Optimizer Changes? Are you talking about my avatar? I gave up on an animated one because other browsers don't display the glitch, so this is just a normal image (I see it glitch slightly, but not in the shouty way my previous one did).

7:41 AM
I can totally see it

so how has PPCG been going? I haven't golfed in ages...

You should totally try out our new tag

@Optimizer Dull to bright? I just see a very subtle shift in the positions of the points of light in Firefox. Which browser are you using?

Firefox only
I meant the dots in there go dull to bright.

Ah I see. I'll see if I can decide on a better image.

@isaacg nice question, I like these
there can be multiple cycles of the same length, right?

Yep
Yeah, it's a good style of question, with the unique sum one

that happened to be less interesting than I expected, but that happens sometimes
on the other hand the similar generate-a-pair-of-integers-from-a-non-negative-one turned out great

finding proof or statement that there is no proof for my solution idea is harder than I thought... (for Every Possible Cycle Length)

@randomra thanks for sorting out the squares. I had thought about summing 1 to n, but that needs too much tweaking afterwards. thanks :)

4:18 PM
@Maltysen just added a byte counter o-lang.herokuapp.com

@phase it counts UTF encoded bytes.
Those are not really the real bytes

@Optimizer then what are the real bytes?

I think the smallest encoding in which the code could fit

1 byte = 8 bits (technicallly). So if all characters of your code belong to extended ASCII set, then each one of them is 1 byte
@phase that very clearly says UTF-8 encoding, no ?
I am not saying that UTF-8 bytes are incorrect. They are mostly inefficient when scoring challenges by bytes.

4:28 PM
I generally make sure that all my characters are in extended ASCII range, which makes 1 char = 1 byte then.
this is very easy to code in JS though in order to integrate with your site

what about o-lang.herokuapp.com/link/code='%C4%ABuo&input= ? how many bytes would that be?

iterate over all characters, check their ASCII code, divide by 255, floor, sum
@phase 5

how do you check the ASCII code of ī?

"ī".charCodeAt(0)

does every even positive integer occur as a gap between two consecutive primes? I can't find any data on this
(a related OEIS entry: oeis.org/A001223)

4:41 PM
Ooh, that's interesting

UTF-8: 3

I have no idea what you are doing. Do you have prior JS experience ?

The nth prime gap is defined as $p_{n+1} - p_n$, [sequence A001223 in OEIX] (http://oeis.org/A001223). What values can occur as a prime gap? Clearly with the exception of $1 = 3 - 2$, all the prime gaps must be even. We also know that this sequence must contain infinitely large numbers, since t...

it's almost assuredly not optimal

var s = "╚";
var count = 0;
for(var i = 0; i < s.length; i++) {
count += Math.ceil(Math.log2(s.charCodeAt(0))/8);

so real answer would be 2

5:12 PM
@isaacg may we assume there are no leading zeroes in the input?

@phase you can explicitly mention it as "ISO 8859" encoding byte count.

@isaacg then there's a fairly trivial solution
map any number containing 0 to itself
