iptables is arcane to me but I got it

be prepared to relearn it then ;p

IIRC they're in the process of replacing that with en.wikipedia.org/wiki/Nftables

@JourneymanGeek yes I knew that... what a nice thing to bear in mind

and fedora uses firewalld rather than iptables now, too

firewalld is a frontend I think

does make it a lot nicer

Anonymous

indeed but i haven't read its docs yet

Anonymous

@JourneymanGeek well fedora docs call it a "dynamic firewall" vs iptables "a static firewall"

@PatoSáinz: since you can apply rules based off location and stuff

to me its still a matter of how its organised over functionality

its a lot easier to manage IMO, which is nice ;p

@JourneymanGeek the command for nftables is nft right?

Does anyone know why this gets timerun error when I upload to UVA?

import java.math.*;
import java.util.*;
class uva11115 {
public static void main(String[] args) {
Scanner scan = new Scanner(System.in);
BigInteger a = new BigInteger("0");
BigInteger cero = new BigInteger("0");
int b;
a=scan.nextBigInteger();
b=scan.nextInt();
while(b!=0 || a.compareTo(cero)!=0){
a=a.pow(b);
System.out.println(a);
a=scan.nextBigInteger();
b=scan.nextInt();
}
}
}

It is my first java program and it runs fine on IDE but it wont work on UVA

hmm....

what is wrong with that line?

It is problem 11115

@dREaM Usually because it's too slow.

it says it is going to end with 0 0

Try more complete testcases.

Try any edge cases.

2:08 AM

but when it is too slow it usually says time limit exceeded

Thanks

I'll try using better testcases

@dREaM Wait, do you mean runtime error?

Because "timerun" really makes no sense.

oh yeah, my bad

@dREaM Check which JRE version the judge is running.

And I guess the source level too.

java 1.7.0 Java Sun SDK

Oh, I see where the problem is

nevermind

@dREaM Hm?

2:18 AM

I thought I had made a mistake which would make the program scan a number that might not exist

But that won't happen.

@dREaM btw, you can use BigInteger.ZERO instead of instantiating another instance

Thanks, I made that change. Although I think I'll still get RE

Hm.

shrug

Maybe .close() the scanner for kicks?

I don't think that's it, but nothing really looks wrong at a glance.

how do I close the scanner?

scan.close() at the end, or make the whole thing a try-with-resources

3:01 AM

@dREaM I was going to say something, but then realised that I was mistaken myself. :)

Well, UVA is down right now, so there's no hurry.

thanks for help everyone

@dREaM Yea, it's pretty easy to exhaustively test all cases.

Something else is wrong.

Maybe the uva judge broke? :P

well, the UVA judge is not working right now :(

@dREaM maybe they took it down to fix it?

some guy called Miguel Frade submitted a problem and everything stopped working :)

@Bob Hopefully :p

@Ramhound You here?

I don't want to carry on an argument in comments, but I have to point out:

1. As far as VirtualBox cares, *it doesn't matter* how many physical CPU packages are installed. Each logical CPU (e.g. core) is treated the same way.
2. VirtualBox doesn't even care about logical CPUs (cores)! Each virtual CPU is exactly equivalent to one *thread* running on the host. You can emulate an 8-CPU guest on a 1-CPU host (albeit slowly).
3. Even if VirtualBox cared about the difference, the fact is that each virtual CPU is presented to the guest as a core in a single CPU package. It does not even attempt to emulate multiple CPU packages (different from multiple logical CPUs as ex…

> The user is attempting to use visualize multiple CPUs in a system that has single CPU.

And? So? That's perfectly possible, completely supported, and completely standard as far as VBox (and, indeed, most other hypervisors) is concerned.

Going back to #1 above, the N2815 has two cores, so it has two CPUs - where a CPU is defined not as a package but rather as an execution core.

But even then you can emulate more than two virtual CPUs!

Heck, in the case of hyperthreading (and similar SMT techniques) you can represent a single execution core as more than one logical CPU, nevermind multiple execution cores.

You've changed the question since it was first posted, I don't know which to address so I'll consider the revision that is latest at the time of writing this. Is answering to a software recommendation request considered spam? No, it's not. Putting a bare link, however is considered as spam...

@allquixotic I've been toying with getting supervisord, or learning to do upstart or systemd scripts for stuff like that.

serversforhackers.com/monitoring-processes-with-supervisord

8:14 PM

@JourneymanGeek pretty sure Upstart can't do it, but the question of "Can systemd ..." always ends in "Yes"

@allquixotic: upstart probably can, but its not really worth learning upstart

supervisord is what we use at work for stuff that dies. A Lot. So... worth learning for me ;p

Don't you hate it when you find an article on a lazy Sunday about an .exe wrapper file for photo viewer on win 10 but don't recall the site or filename or the title of the article

Also, I LOVE those documentation

lol

so you can't FIND it later?

I have a thing for that.

driving me up the wall

check history? Put it into pocket or something?

9:05 PM

turns out I don't need it

does not appear in history

and I didn't dream it....i think

these websites have horrible search routines...

I am thinking the article must have been taken down or something because I simply cannot find it

@Ramhound Is that to replace that weird iconless thing that pops up when you open photos under Win10? :P

howtogeek.com/225844/…

Give that a crack

It is so you can use it to "open with" on imags.

Yeah, I know about that

Oh, then ^

I just hate not being able to find something

its like i never visted it

Ahhh, okay.
