"then completely screw everything up in v2" <--- first sign of guerilla language design

Alex A.

@El'endiaStarman If it makes you feel any better, the company I work for doesn't use version control and all development and testing is done in production.

El'endia Starman

GAH.

Alex A.

@AlexA. Note to self: When the interviewer asks "Any questions?", instead of saying no say "Do you use version control?" and stop the interview if they answer to the negative

@Calvin'sHobbies Do you like my tacos?

Oh, by the way @Sp3000, have you see my PyAcidic Musings gist?

Alex A.

@Sp3000 Yeah... :|

@El'endiaStarman Yes, I did

Alex A.

Interviewer: "Any questions?"
Me: "Do you use version control?"
Interviewer: "Of course! We use Subversion."
Me: ಠ_ಠ "Alright, goodbye."

Yeah it's actually pretty nice

Alex A.

Right. The applications development group at my company uses that but the statistics group, where I work, uses no version control because "people don't want to have to learn new systems."

@Ale you say the first ingredient gets 6 chars on the top line, isn't it 4? Is the CREAMS correct in the example?

Alex A.

@Calvin'sHobbies The first ingredient is at the bottom of the taco. Ingredients go bottom to top.

So the one at the bottom is 6 chars then 4, the one at the top is 4 then 6.

CREAMS is the end SOURCREAM wrapped

Since the top like is 4 chars (SOUR) and the bottom is only 5 (CREAM) we add 1 because the bottom has to be 6, so it makes SOURCREAMS

Q: (0,1)-vector XOR problem

this is a rewrite of another recent question of mine [1] that wasnt stated well (it had a semi obvious simplification, mea culpa) but I think theres still a nontrivial question at the heart of it. have seen similar problems in the literature but not this one in particular. will write it in terms...

second answer

it's NP-complete though, not NP-hard

xnor

ah nice

NP complete problems are exactly the problems that are both NP hard and in NP

orlp

well

so much for my nice general solution :(

this doesn't mean that the safe problem is NP-complete, but it does mean that my matrix approach sucks

(for optimal answers - for getting working answers it's great)

ev3commander

heyyy

orlp

=/

that makes me sad

I thought I was doing something useful with matrices but nope

NP comes to stomp on the party again

Sp3000

00:59

@orlp On the bright side it gives an easy way to check solvability

Woop nvm you said that

orlp

on the positive hand

I did write a solver, which is general for any these kind of problems

Okay, anyone who knows Unix and Python...halp.

import resource
import os
import signal

def timeRanOut(n, stack):
    raise SystemExit('ran out of time!')
signal.signal(signal.SIGXCPU, timeRanOut)


soft,hard = resource.getrlimit(resource.RLIMIT_CPU)
print(soft,hard)
resource.setrlimit(resource.RLIMIT_CPU, (10, 100))

y = 10**(10**10)

So, here, I set the CPU time limit for this process to 10 seconds, then I attempt to calculate some huge number.

I have a signal handler that is run when the CPU time limit is exceeded.

However, I only see it when I Ctrl+C after 10 seconds.

Also strange: I don't see the -1 -1 from print(soft,hard) until after I hit Ctrl+C.

PhiNotPi

That last thing may have to do with flushing, although I'm not pythoner.

maybe this: stackoverflow.com/questions/230751/…

El'endia Starman

Yeah, lemme add that.

Nope, that didn't work.

print(soft,hard,flush=True) didn't work either.

PhiNotPi

what happens if you replace the large number calculation with a sleep()? Although, the time spent sleeping may not count towards the time limit.

El'endia Starman

I tried putting time.sleep(2) in between the print and the large number, and that didn't seem to make a difference.

Replaced y=10**(10**10) with y=10**10, and the print and sleep lines work as expected.

PhiNotPi

01:41

So, if the calculation is small, it prints before sleeping, but if it is large, it doesn't?

El'endia Starman

Apparently so.

Well, it's really hard to tell where it is in the code since printing doesn't work.

PhiNotPi

This feels like it could be the result of Python trying to act "smart" by "optimizing" where the constant is computed, but then backfiring.

El'endia Starman

That's my guess too.

PhiNotPi

But I'm don't know enough about Python to know whether or not that's the kind of stuff Python does.

Thomas Kwa

Can someone delete codegolf.stackexchange.com/a/41849/39328 ? It's wrong, because TI-BASIC's substring indexing doesn't wrap. I left a comment 6 months ago, but the answerer never responded, and my recent flag was disputed.

El'endia Starman

01:45

Perhaps Python split off a separate process or something for the calculation of that number?

Q: Python "preemptively" hangs when trying to calculate a very large number?

I've asked this question before about killing a process that uses too much memory, and I've got most of a solution worked out. However, there is one problem: calculating massive numbers seems to be untouched by the method I'm trying to use. This code below is intended to put a 10 second CPU time ...

Most of the code is correct. Only the bottom part below the large comment is giving the error
Again here is the text file: pastebin.com/NEPk7eME and here is the code: pastebin.com/1sUfMPvm
