A: Sandbox for Proposed Challenges

Everything about PI code-golf Pi is the most popular transcedental number. As a result, pi have thoroughly studied. This challenge is in spirit of 9-Hole challenge. 1. Digits of PI Given n and k, output n'th digit before point on base-k representation. 5 10 9 10 2 0 6 16 10 If the base is ...

Great timing @NewSandboxedPosts!

@wizzwizz4 both jobs are running... I'll check my mailbox... waiting for the SD card for the 2nd cubietruck...

wizzwizz4

@yeti If we ditch the header file and rename the extra .c file to a .h file, it will compile more doesn't for future compilations as it won't save more time than has been spent running the code so far.

yeti

I won't interrupt 'em now

no no no...

:-)

mybe some milliseconds can be gained by loop-unrolling...

but just waiting 2% longer is the cheaper operation

;-)

wizzwizz4

Yes.

But, if there was a system failure, it would be more efficient to use the .c file as a header instead of the header that refers to the .c file, because then the compiler can use inlining.

yeti

or jus make an all-in-one c file with some fat comments about where to split if preferring separate files...

wizzwizz4

12:49

Yeah, but then some would be mine and some would be somebody else's...

yeti

ok... that's a reason...

the "edit" feature has vanished.... i cannot correct my typos any more... straaaanage

wizzwizz4

So I don't have a massive urge to ask whether it is finished all the time, could you @ping me when it's done?

The edit feature isn't gone, it's just you can only edit for a certain amount of time unless you're a mod.

yeti

@wizzwizz4 ping test!

wizzwizz4

@yeti pong test!

yeti

;-)

ok

wizzwizz4

12:52

Say something

yeti

something

wizzwizz4

@wizzwizz4 ping-pong test!

Too many people chatting. Impossible to do a self-reply w/o edits! :-(

yeti

/me is sloooow today... probably migraine-weahther

being able to edit is brutal... in irc I just live with my typos...

wizzwizz4

How long has it been running? Edit: edited this post

yeti

and it is ok that way

the 2nd one has 73min according to top

it was started arount about 10 minutes after the 1st

CPU states: 12.5% user, 0.0% nice, 0.0% system, 0.0% interrupt, 87.5% idle

...on the 8-core box

1 cpu at 99.x% is ~12.5&

wizzwizz4

12:57

8 cores?!? You can run 8 different processes on that box. If you offset the starting seed by 2^29 each time...

yeti

but that'll be unfair on a multi user box

it is not exclusively mine

wizzwizz4

Ok. 4 processes? ;p jk

yeti

I have a 4core-PI

;-)

or 2

wizzwizz4

I have a Raspberry Pi too.

But it's no good for this sort of thing.

yeti

atm only 1 PI and one cubie3 are running... 'm short on big SD cards...

migraine weather ==> more typos ;-(

wizzwizz4

13:01

Typos ==> more typos

yeti

/me wants a way to convert typos into power... a typo power plant!

I invented an alzheimer power plant

wizzwizz4

S***. The nice people on Code Review just pointed out to me that I made a typo.

In the source code.

yeti

what? where?

why? how?

;-)

so I should stop both jobs?

wizzwizz4

I think so. I'll update the GitHub gist.

yeti

ok

wizzwizz4

13:07

Ok. I've updated the GitHub gist. Now it should actually spit out a value.

My previous version worked, but a computer glitch overwrote it with null bytes. :-( I forgot to test this version.

Actually, there is a 1 / 2^(86) chance of actually generating a seed.

Maybe we shouldn't do this. It could just be a waste of time.

yeti

no more header?

wizzwizz4

mt19937ar is meant to end in .h

Just rename it to fix the problem.

yeti

ok..

wizzwizz4

The only thing this program will prove now is whether or not a Hello, World program actually exists in Seed.

yeti

then m*.h includes itself

wizzwizz4

13:16

It probably won't find one.

yeti

mooooment...

wizzwizz4

m*.h shouldn't include itself anymore. Take out that line. I really haven't been doing this properly...

The chances of a seed program existing are just over 0.00000000000000000000000002

yeti

both running

wizzwizz4

Do you know when overflows occur?

yeti

no

which ones?

wizzwizz4

13:22

Or the approximate speed of calculation?

Because if you know the speed of calculation then you know about when it has overflowed.

And when it is seeding with values it has already checked.

yeti

64bit xeon @2.3ghz

thats all I know about the single cores of the 8-core one

wizzwizz4

Because if the program doesn't find anything, and the chances of it finding anything are slim, it will never stop running.

yeti

the other one seems to be single core

/proc is not mounted

:-(

no idea how fast

wizzwizz4

There's probably no point running the code.

yeti

make a super interesting website and embed the search in parts as JS...

mwhuaahahaahahahaa

advertise superkittenporn and millions of visitors give you CPU time

dorothy

13:29

eek! downvotes for codegolf.stackexchange.com/q/68176/21585

anyone know why?

yeti

because it is boring?

maybe I just didnt see the fun in it

dorothy

@yeti really???

is that a reason to downvote these days?

(and it's not boring!)

yeti

but i didnt vote at all

dorothy

unless you think math is boring of course

yeti

I dont like calculating

wizzwizz4

13:33

@yeti Actually, I am planning to create a website... I've had this idea hundreds of times before, but never actually when I'm creating a website. I think I'll build some calculation code into the core JS framework so that when the framework gets complicated, it will be impossible to extract and remove the calculation code. Mwahahaha.

yeti

but jumping arround the numbers to construct divisors or primes is fun

or thinking about integers as multidimensional tuples where each "dimension" is a prime and the coordinate is how often that factor is in that number...

or unrolling euratosthenes...

no... definitely I do like maths... but maybe just other parts of her

dorothy

@yeti fair enough.. as a simple coding exercise I also think it has possibility for golfing

you basically have to make a histogram of all the possible values of Mx

HEy um here

@wizzwizz4 hi

dorothy

I am shocked by the downvotes :(

@BlockCoder1392 Hi. You've got a mask, I have a beard. But they're both hats. (?!?)

/me thinks downvotes should be done visibly and need a comment

dorothy

me too

yeti

anonymous downvotes are a design flaw

@BlockCoder1392 That website had an invalid certificate.

Doorknob 冰

that wasn't an https link

wizzwizz4

Oh. I was temporarily intercepted then.

dorothy

my main problem is how to paste in the math from the wiki page

BlockCoder1392

@wizzwizz4 Fixed; it was HTTP instead of HTTPS

wizzwizz4

13:48

It's not meant to be HTTPS I don't think.

Whenever I've used it before it's been HTTP.

BlockCoder1392

[the website] was http not https

wizzwizz4

Yes.

Q: Cracking the Enigma?

Introduction The Enigma was one of the first electro-mechanical rotor cipher machines used in World War II. That means that after a single letter is coded, it would change the key for the next letter. This was considered unbreakable by the Germans, due to the enormous key space. Even brute-forci...

Well, I just beat java.

Optimizer

you should be proud

SuperJedi224

I beat java at something non-trivial using BotEngine.

Probably the most d instructions I've ever used in one BotEngine program.

(Actually, after some further revisions, it scores a full eighteen orders of magnitude better than java- and only five orders of magnitude worse than C++)

Of course, the winning answer still outperforms it by sixty-four orders of magnitude.

Should we use the fancy chat event scheduling tool to schedule a (UTC) New Year's party? :P

@Doorknob冰 am I invited? :3

Suddenly I don't feel like a no-life hue hue

@NewMainPosts You know what bothers me about this?

The person has an account on SO with 480 rep

And they still posted it here

...

trichoplax

16:56

I'm guessing in this case they simply posted to the wrong site accidentally, rather than thinking this was an appropriate place. Most people will realise they are on a different SE site after following HNQ links, but every so often we'll get someone who doesn't, with no ill intention.

quartata

I suppose.

Maybe we need a blinking red marquee that says THIS ISN'T STACKOVERFLOW on the top of the ask question page

trichoplax

I don't think we need to make anything any clearer - it happens rarely enough that the current presentation seems sufficient

@quartata lol - annoy 999 people in the hope that the 1 mistaken user will be dissuaded from posting ;)
