Because astronaut food sucks

Maltysen

@HelkaHomba are you secretly elon musk?

@Maltysen er, no

@Fatalize I'd go to space but I doubt I'd try bungee jumping

@HelkaHomba WHY NOT BOTH?

Fatalize

6:02 PM

well yeah cause space is infinitely cooler

Spacebungee!

@HelkaHomba mod abuse eleven

But really I do not know which is safer, bungee jumping or going to space.

The TF2 wiki is starting to golf their weapon demonstrations: youtube.com/watch?v=SnR748ENI4M&nohtml5=False

@flawr Presently surely it's bungee jumping.

6:05 PM

@HelkaHomba I'd imagine bungee jumping is pretty unsafe though.

At least if you don't know what you're doing

@quartata Same for flying spaceships :P

@HelkaHomba Are you sure? What kind of comparision, number of (fatal?) accidents per jump/launch ?

LADIES AND GENTLEMEN, AFTER HOURS OF TURMOIL, I HAVE FINALLY SOLVED D!

LegionMammal978

@CᴏɴᴏʀO'Bʀɪᴇɴ You have me stumped... There are three sequences meeting the constraints (a(5)=40, a(8)=128, offset 0) and can't figure out how to do any of them in 13 characters.

\o/\o/\o/\o/\o/\o/\o/\o/\o/

6:08 PM

@flawr I'm not sure. Here's some data. And some more

Cᴏɴᴏʀ O'Bʀɪᴇɴ

@LegionMammal978 \o/ good luck

LADIES AND GENTLEMEN, AFTER HOURS OF TURMOIL, SCIENTISTS FOUND NO LINK BETWEEN THE LETTER D AND MATH!

@MarsUltor @Sp3000 @xsot Rest assured, that even with what is probably far, far too much discussion, it still took some ingenuity and a lot of bashing my head against the keyboard to find a good solution. Thank you all!

@zyabin101 t(-_-t

Cᴏɴᴏʀ O'Bʀɪᴇɴ

@zyabin101 I will derive from that statements that derivatives are D.

@zyabin101 Code Jam, dangit XD I solved the D challenge, at last

Now I can finally get some sleep

6:12 PM

@Sherlock9 Darn, @ 19:41:32.

2007 Sherlock9 100 19:41:32

@flawr You could say that learning all the things needed for spaceflight is harder and therefore more dangerous for the average person who may not remember them.

I'll take the penalty, zyabin. I just wanted to solve the challenge

But congrats for the perfect score!

Thank you :D

Solver

Hello!

6:15 PM

@HelkaHomba Just takes some patience to learn.

@Solver o/

So according to wikipedia there have been 551 people to space. (I was unable to find the number of flights.)

And 32 space-travelers who died in space-accidents.

32/551 is slightly less than 6%. Considering many of those astronauts have been to space multiple times. The 'rate' deaths/fligh is significantly lower than 6%

El'endia Starman

@HelkaHomba That's insane. It's under 2 dollars here.

LegionMammal978

5.8%

@flawr 32 / 551 = 0.058076225045372050816696914700544

ninja'd

6:19 PM

of course we can discuss them and check everybody's code after it's over

@El'endiaStarman Are you signed up for Google Code Jam? I'd like to add all the PPCG people as friends on there

@aditsu Oh dear. I left in a lot of print statements for debugging o_o

If so, what is your username?

@Dennis That's scary

That code is going to look a little ugly :)

doesn't matter

El'endia Starman

6:20 PM

@Sherlock9 Not this year.

Regarding base jumping accidents I did only find the number 1 in 500000 so far. But all those sources probably copied eachother.

@Sherlock9 So, you'll get WA?

(Wrong Answer)

For what problem?

@quartata Close, though I'd still indent it differently to get rid of the dangling open paren in the first line.

I shouldn't, should I? The output file is different from the source code

There are prints in all of them, I think

I could submit D small, but the reminder is pretty wise

6:22 PM

@QPaysTaxes Why?

(let*-values ([(side1 side2) (partition (lambda (x)
                                          (zero? (bitwise-and x 2)))
                                        (shuffle (range 16)))]
              [(chunks) (append-map list side1 side2)]
              [(rooms) (random 6 11)])
  (for ([chunk chunks] [room rooms])
    (displayln chunk)))

@ChrisJester-Young OK, I was wondering about the open paren

(let*-values
    ([(side1 side2) (partition (lambda (x) (zero? (bitwise-and x 2)))
                               (shuffle (range 16)))]
     [(chunks) (append-map list side1 side2)]
     [(rooms) (random 6 11)])
  (for ([chunk chunks] [room rooms])
    (displayln chunk)))

^ two different ways to reindent to remove the dangling open paren.

I think I'll just move the paren to the next line yeah

@QPaysTaxes you need to figure out exactly how many students you need

6:23 PM

(and reindent the let clauses)

@quartata Cool. I use DrRacket's auto-indenter to help with stuff too.

@HelkaHomba Where's the option "No - that guy looks overconfident and I don't like the fact that he took Tesla's name for his company"

@zyabin101 There are prints in the source code for C-large, D-small and D-large

@LuisMendo He didn't actually start the company, I think he was an angel investor

@Sherlock9 Make a habit of printing debug stuff to stderr instead of stdout.

6:24 PM

So I don't think he picked the name

That way they won't accidentally end up in the output.

@Sherlock9 Oh noes.

Three WAs. O_O

Dennis

@LuisMendo hahahaha

@ChrisJester-Young The way I wrote the output is the following:

with open("A-large.out", 'w') as file:
    for string in cases:
        file.write(string)

@LuisMendo you're back!

6:25 PM

@flawr I guess I figured bungee is safer because it's so much more common. A competent bungee company probably almost never has accidents. But even giant state governments can't be sure about space flight.

@QPaysTaxes oh, you can't read the problems?

@QPaysTaxes Oh sorry, I was talking about bungee jumping.

@Sherlock9 Cool. Then you wouldn't even be writing debug stuff to file. ;-)

@QPaysTaxes Yes, anybody can read them.

@QPaysTaxes go to the code jam page and see if you can get in and watch

@ChrisJester-Young Nope, print is for running code (I don't know how to read stderr, unfortunately) and the correct output is for the output file

6:27 PM

@HelkaHomba Well we are still only talking about fatalities. While reading about bungee jumping I read that eye damages are quite frequent (due to the sudden shift of blood)

@quartata TIL :-)

@zyabin101 See above discussion. I believe I'm fine

@zyabin101 for a while :-)

Well I think I'd still do both=)

@LuisMendo Although I agree that I don't like that they use Tesla's name for it

6:28 PM

If I had the chance/the money.

@quartata Too pretentious for my taste

Yeah

Maltysen

\o/ fractiles-small correct

@LuisMendo Hi!

@flawr Hello!

6:28 PM

@LuisMendo What would you have preferred? Would you rather be driving around a Faraday? (far-a-day, geddit? :P)

@HelkaHomba Hahaha

Good that you explained

That's hard for non-natives

Maltysen

@QPaysTaxes they're just smaller, except for problem D which is actually different

> Reston VA fastfood worker Eric Barcia assembles a bungee cord reaching nearly 70 feet in length and jumps from a 70 foot railroad trestle. Barcia did not take into account the fact that a bungee stretches on use, therefore his head impacted the pavement at the full force of gravity.

I'm expecting a Matlab answer from you in the robbers channege :-) @flawr

What challenge?

Dennis

6:31 PM

@LuisMendo Would have to be Octave.

@HelkaHomba Where's the option for: "Yes, when Teslas and charging stations are available in my country and especially on my mountainous, overcrowded-with-little-space-for-those-charging-stations-without-displacing-som‌e-inhabitants island" :D

@Sherlock9 stderr is for writing to, not reading from. ;-) In Ruby (I don't know Python, sorry), you use puts for writing to stdout and warn for writing to stderr. That way contest output is separated from debug messages.

You wanna say there is something on this site other than the chat?

Q: Find the program that prints this integer sequence (Cops' thread)

@flawr Sorry, I meant the cops'

This is the cops' thread. The robbers' thread goes here. The last cops-and-robbers thread was already 4 months ago. The cop's task The cop's task is to write a program/function that takes a positive (or non-negative) integer and outputs/returns another integer. The cop must state it if the pr...

cops-and-robbers

@QPaysTaxes I did not star!

@LuisMendo Oh , let me see=)

6:32 PM

@Dennis Good point

@ChrisJester-Young I just mean, how can I read those messages while the code is running?
