can I run a script in a tty and still have it interact with my GUI (F7)

hbdgaf

as long as you set $DISPLAY, sure

I was just looking at this script, it seems to be a persistent running one, and was wondering if I could put it in the back without using the regular terminal emulator

A: Script doesn't run via crontab but works fine standalone

One thing at a time: First let's give you a user based bin folder: cd ~/ && mkdir bin You want to use crontab. Let's start with something really simple: * * * * * touch /tmp/testing.txt Okay, so that works Now let's try running a script that does the same * * * * * /home/username/bin/to...

@hbdgaf improved

btw, try to avoid "problem" in titles

hbdgaf

The point was that the previous edit bumped mergelist off the side of a scrollbar to try and hide it, so I made it blatantly obvious.

John Baber

I don't think this question is a duplicate, but a bunch of people say so. Am I missing something? askubuntu.com/questions/506582/…

Braiam

> Can you tell how to upgrade Ubuntu 12.10 to Ubuntu 14.04 LTS or any other version

John Baber

The question asks "How do I upgrade from 12.10 to something modern since it's end of life do-release-upgrade doesn't work" and the duplicate is "I want to stay with this end of life version of ubuntu, how do I install software from an exotic repository"

hbdgaf

@JohnBaber the uestion might be a little different, but the answer is identical. in that case we usually -> canonical

Braiam

1:14 AM

@JohnBaber err... no

John Baber

The answer to the "duplicate" doesn't help with the original question at all. Ashish seems to be asking a legitimate (and difficult to answer) question.

hbdgaf

no. you've got two people saying it. i'll go find more if you need it.

Braiam

@JohnBaber in 10 words tell me what OP is asking

John Baber

"How do I upgrade from 12.10 to something supported?"

Braiam

What you need to do in order to do so?

hbdgaf

1:17 AM

"or upgrade from old unsupported release? "

John Baber

Yes, upgrade from an old unsupported release.

hbdgaf

see the dupe

Braiam

@hbdgaf I don't remember that scene... is House MD alright?

hbdgaf

he'll be alright, just needs a little pain medication

John Baber

What's recommended there doesn't work for me in the same situation.

The accepted answer and others seem to be saying what it takes to see old packages.

hbdgaf

1:24 AM

then figure it out and improve the answer... what are you trying to do and how is it failing... be specific.

Mateo

@JohnBaber what dosn't work where?

hbdgaf

^^ what are you trying to do and how is it failing... be specific.

John Baber

Replacing urls in source.list with old-release doesn't make `do-release-upgrade` work.

Braiam

did you do sudo apt-get update?

John Baber

Yes.

hbdgaf

1:26 AM

then purge the ppas you have installed, unpin everything you have pinned, and upgrade

and what machine?

I have a small arm box, that didn't have a trusty image, and didn't properly upgrade, I just changed the sources to say "trusty" and did dist-upgrade, there are certain situations, but we need details

John Baber

In trying to mess figure out the answer to the problem in the first place, I kept replacing things in sources.list

Eventually I had `pangolin` everywhere when I'm really quetzal.

I think I've fixed the source.list and am apt-get update-ing again.

Braiam

1:31 AM

@JohnBaber lets do this. Ask a question with the exact error everything is throwing, the contents of your sources.list and the output of apt-cache policy libc6

Mateo

basically did this to it:

John Baber

Yeah if what I'm doing now doesn't magically work, I'll make a proper question.

Mateo

John Baber

I'd love it if some strong-arming like Mateo is describing would just work.

Mateo

@JohnBaber isn't that more a downgrade?

hbdgaf

1:32 AM

It sounds like you're trying to do something against what you're supposed to do. Pull out any non-mainline stuff. Increment your release and dist-upgrade one at a time until you hit LTS. Then you can leapfrog. Going backwards is bad. You're bound to paint yourself in to a corner and build a worse problem than you started with...

Mateo

well, it dosn't work very well...

Braiam

@JohnBaber if everything fails: backup and reinstall

John Baber

The one at a time was the plan, but I was trying to deal with the fact that dist-upgrade wasn't working.

@Braiam: Nooooooooo

It's my fault for installing a non-LTS.

hbdgaf

It only doesn't work because you pinned something or have a ppa activated.

Braiam

John Baber

1:34 AM

Woohoo, do-release-upgrade is trying to work.

Mateo

way too much to mess with, but if there is a perfectly fine image to start from scratch with, you should do it

John Baber

This is a remarkably specific problem (the fake 'pangolin' being in there.)

Yeah, this seems to be working. Thanks for being rubber ducks!

hbdgaf

So, it's not a dupe because you created a corner case impossible to arrive at by using things the way you're supposed to and now you want it not to be a dupe? or it's solved now?

John Baber

Oh yeah, my case is too weird and specific.

It would just be noise to have it as a question.

hbdgaf

>.>

John Baber

1:36 AM

No, that question's a dupe.

I thought it wasn't working because the answer wasn't correct, not because I had a weird problem.

Mateo

doesn't matter if a package is installed. if you install blarg_i_want_to_waste_time.deb and don't purge the package despite someone saying purge your ppas, you built your problem.

John Baber

I'm not denying that the problem was created by my meddling.

I didn't understand "purge your ppas".

A bit late to the party but I found this question when looking for an answer and now I have my own answer to share. I believe you can do this via the mysterious world of apt_preferences. Try making a file called /tmp/a_p (or whatever) like so... Package: * Pin: release a=*-backports Pin-Priori...

CSS... >:(

Mateo

@NathanOsman what did it do this time?

Nathan Osman

Spent at least two hours today trying to tell a <div> to fill the remaining space of its parent.

Braiam

@JohnBaber if you continue to meddling you could cripple your system or have some weird cruft out the upgrade process that can cause problems later, and everything could be avoided if you just backup/reinstall

hbdgaf

@NathanOsman css is a pita that way

Nathan Osman

Even with JavaScript, it was nearly impossible to achieve the desired output.

@hbdgaf It's just not cut out for vertical positioning.

I might have been able to accomplish my goal with tables... but I was too exhausted to try.

I finally gave up and let the <div> just be as large as its contents.

I'm tempted to start writing something in JavaScript that abstracts CSS's box model and presents something simpler.

Mateo

three div's with percentages

Nathan Osman

// Something like this
var box = new Box();
var layout = new Layout();
layout.add(
    box,
    250,      // horizontal
    'stretch' // vertical
);

Q: Outer Div will not stretch to fit inner div (using clear)

I've been reading about how elements with the float attribute do not have their height accounted for. Therefore, I should use clear:both right before the end of the parent div so that it will stretch over the entire inner div. You can see on This Page that the div with the id full-height-templat...

has anyone ever had the problem of your computer (according to htop) not swapping?

right now.. I am running high memory usage (close to 75-90%) at all times and it doesn't appear to be running anything through swap files

I had default swappiness of 60, and did a temporary swappiness of 80 to see if that would do anything, but wonder if that is why I have been locking up a lot lately

@NoTime Do you have a swap partition set up?

yes.. I am looking at free -m and it is showing 1933 available 0 used

it's showing -1 priority (not sure what that means or how to change it)

looking online for this..
