@LeakyNun does it say that input must always be fruitful ?

like there is no input without output ?

Leaky Nun

Just use all the testcases? I'm not sure what you mean

Maybe use an example to demonstrate what you mean?

@LeakyNun That's actually the word "suck"

@LeakyNun i think it is fine !

@Agawa001 then post it?

@LeakyNun i thought i missed some rules

What does 2**(-2**(-2**(-2**(.... converge to?

Leaky Nun

Let it converge to x

Then x = 2**(-x)

@LeakyNun Uh what

3:13 PM

....and then...?

From graphical method, x ~ 0.6412

(this equation has no closed form solution, unless you use the W function)

x = 2**-x
x*2**x = 1

Let x = y/ln2

(y/ln2)*e**y = 1
y*e**y = ln2
y = W(ln2)

zyabin101

Good! Now write a Brainfuck IDE in CJam!

Agawa001

@LeakyNun i dont see the point of making random rules like this

Leaky Nun

@Agawa001 Which rule are you referring to?

Agawa001

why does the function output nothing when two square-values occur of same weight ?

this is so random

Leaky Nun

3:20 PM

accept it

Agawa001

my function works fine until this point

Leaky Nun

doesn't your function have something like if length output > 2 output nothing?

Agawa001

my function generates ONE output

:)

this is the charm of maths

Leaky Nun

@LeakyNun I'm curious why it worked, my name definitely doesn't start with "bal"

And why wasn't bald banthana pinged instead of me

@LeakyNun done! take a look at my magic

@Agawa001 Why are there 4 initial spaces?

@LeakyNun I dont know what that means !

Idk, it's pretty simple. Which isn't necessarily a bad thing.

Bálint

@Quill index.js? Ughh...

Agawa001

@LeakyNun if u see deep in my code, there is no for loop, neither recursivity

@Jakube heb did ?

zyabin101

@Jakube Sp3000 won a T-Shirt?

Agawa001

google-jam ?

Jakube

Yep

Leaky Nun

4:35 PM

@Agawa001 I suppose b is the number square... other than that I don't know how it works at all

Sp3000

@Jakube Thanks :) I wish I could figure out how to calculate red tape's probability efficiently, but I gave up and bashed out the easy ones instead

Agawa001

@LeakyNun pure maths

@Sp3000 google_jam ?

Sp3000

Code Jam, yeah

aditsu

@Sp3000 congrats..

Jakube

Submitted a brute-force solution for C-small in the last minute.

Leaky Nun

4:37 PM

@Agawa001 Is there no a+=2?

Agawa001

@Sp3000 and now you will wear that tshirt 7/7 24/24

@LeakyNun what do u mean ?

aditsu

I epic-failed (T_T) ( ╯°□°)╯ ┻━━┻

Leaky Nun

@Agawa001 Does a+=2 do anything at all?

Upgoat

Is anyone here familiar with wordpress?

aditsu

I had a stupid bug for C, fixed it almost at the last minute, and it was still wrong

Agawa001

4:38 PM

@LeakyNun nah, not in matlab

Leaky Nun

oh, ok

Agawa001

there is things which must be golfed, conditions and repetitive rounding and modulating

i used mod and fix atleast 5 times for each

aditsu

@Lynn I wrote one too, I think yours is shorter

Sp3000

Just asked a friend about B large - he said he calculated product (px+(1-p)) for each probability, then found the coefficient of x^n

And here I was trying to get an explicit formula :/

Lynn

It would be fun to compare them, @aditsu

Agawa001

4:40 PM

but im still proud of myself, i did nothing such an array of combinations or recursivity

zyabin101

@Sp30000 congratulations on reaching a T-Shirt!

@Upgoat Ish.

Agawa001

if i had this tshirt i would wear it even when i sleep

aditsu

@zyabin101 can haz leaderboard?

Upgoat

@El'endiaStarman okay, well I have a subdomain at blog.vihan.org but for some reason wordpress seems to think it's at www.vihan.org so all urls are set to the wrong subdomain, hence, causing everything to be borked. Would you know how to fix this?

zyabin101

@aditsu I lost Firefox, and as such, the leaderboard bookmarklet.

It'll take time for recover.

Leaky Nun

@Agawa001 I just found the gem of your solution....

Agawa001

@LeakyNun i am writing an explanation right now, maybe you can golf it further using ur language

aditsu

4:43 PM

oh

Leaky Nun

I don't think it would be shorter using a closed form solution

brute force always is the shortest

Agawa001

not always

aditsu

@Lynn one version is:

Q: Alternating Sign Sequence

Introduction The sign of a number is either a +, or a - for every non-zero integer. Zero itself is signless (+0 is the same as -0). In the following sequence, we are going to alternate between the positive sign, the zero and the negative sign. The sequence starts with 1, so we write 1 with a pos...

now

keep an eye with me

See you on the code jam next year or so :'(

Agawa001

the amount stored in (a,d) is maximal

aditsu

@zyabin101 there's GDCJ tomorrow

Agawa001

4:47 PM

and if we subtract values from (ad) , they must be multiples of 11

are u with me @LeakyNun

Leaky Nun

@Agawa001 yes, please continue

Agawa001

since they are multiples of 11

zyabin101

@aditsu Good! Who's participating?

Agawa001

the weigh is 4+1 = 5

zyabin101

@Sp3000, @Jakube, @TheNumberOne and you, right?

aditsu

4:48 PM

@zyabin101 I think everybody from round 2 can participate

Agawa001

while the weight of (b,c) is 2+3=5

zyabin101

@aditsu Yes, they can.

aditsu

I'll do it

first I have to find out how it works :p

Agawa001

but rather then adding the weight to both b, and c, we just add it two times to the value with lower weight

it means b

adding even value to b until it reaches 9 or 8 then we must stop

we dont want a weight of 3

Leaky Nun

@Agawa001 Why don't you just post your explanation there?

Agawa001

4:50 PM

im lazy iv done hard work matching my equation to all test cases

i will add it tomorrow

Shit! There was one wrong number in my solution for C-small.

nah, they have docs too. check the "develop" tab

Lynn

@RenderSettings: This Urbit server seems really slow and irresponsive. >.>

Lots of little loading icons.

zyabin101

@Lynn -._(._.)_.-

@Lynn In creation, yes.

Lots of the time especially go to talking with %ames in an unknown language and downloading files over Urbit itself. Oh, and 2GB of memory, either physical or swap, is required.

It won't be used fully, however, just that it has to be available at the time.

Are you going to create a new urbit?

I wish to, but I don't have enough resources available.

At home, there's only one gigabyte of memory, which isn't enough for an Ubuntu virtual machine.

At Dad's home, there's a PC with four gigs, just that it isn't always available, and two gigs for an Ubuntu VM is already half of the memory.

And swap is really inefficient.

I could have an Urbit instance on C9, but that's not fair, as we know. ;)

-._(._.)_.-

Currently having my own urbit is only a dream in my head.

@Lynn I'm interested, are you going to create your own Urbit?

Lynn

Ahh, well, I’m more interested in Hoon/Nock than in Urbit itself.

@Upgoat *Relatively

mınxomaτ

@Upgoat No, not really. You need to understand how datacenters work ;-)

These servers are sold when a larger contractor de-allocates a few servers. So now they have 1-5 servers at a time that can't be sold, because on their own, they are not powerful enough for relevant clients.

Upgoat

@mınxomaτ ._. well I'm stuck with digitalocean for a month... idk if it'll be a pain in the but to transfer everything to OVH if I switch

mınxomaτ

@Upgoat Install whatever OS -> do whatever you want. How painful that is depends entirely on you :P

El'endia Starman

@EᴀsᴛᴇʀʟʏIʀᴋ 512 MB is, surprisingly, more than enough for hosting web sites that don't get huge amounts of traffic. Mainly that's because users aren't running typical software that needs plenty of RAM.

Heck, for my websites, the disk usage and bandwidth usage can both be measured in megabytes.
