Q: Can't Launch Freemind in Ubuntu 15.10 - Please Advise

For a long while I've had difficulty launching the program Freemind in Ubuntu 15.10: sudo apt-get install freemind Please take a look at the bug I submitted: https://bugs.launchpad.net/ubuntu/+source/openjdk-7/+bug/1445598 I'm hoping that someone here can view the details linked above and sug...

Well, interesting day with coffee machines blowing up so I think I'll call it a night! Goodnight everyone! :)

Zacharee1

lol

goodnight @ParanoidPanda

Zacharee1

12:27 AM

112 rep to go

Going well to 3k

hbdgaf

Good job. Gaining rep was easier a few years ago.

Zacharee1

easier?

hbdgaf

Yes. Think about how many non-version specific questions are already answered. How many "duplicates" do we get a day that were valid question six months, a year, etc ago?

Zacharee1

ah

true

Serg

Eh, still plenty to choose from. And with 16.04 around the corner there should be new things to learn and answer

Zacharee1

12:38 AM

maybe

Serg

You could always pick up a new language and start answering questions that are possible to achieve through those. Since I'm gonna be doing Python i hope to do more questions with that. Diversity in knowledge is always a good investment of time and effort

Zacharee1

I don't have the time :(

I'm learning Arduino, but there aren't many questions about that

Serg

@seth @Fabby Hehe, off bu one letter in the name there. Ironically enough, Fedora 20 was the second distro I've ever tried.

@Zacharee1 there's a stackexchange site for that too. And you could go into electronics site , the microcontroller programming is on topic there

Zacharee1

I know, but this is where I've built my rep, and I like it here :)

hbdgaf

@Zacharee1 Not maybe, definitely. Look at anyone that has a massive rep spike. It happens around release dates for a reason.

Zacharee1

12:46 AM

Hmm

Well I'll hopefully be around

Seth

@Serg lol

Mateo

ooo, this looks like a fun command:

Seth

ooh haha

can you copy it here? :P

hbdgaf

@Mateo That your command-fu scope?

Mateo

can't wait till I can pipe that into the phone terminal ;)

while true; do printf "\e[38;5;$(($(od -d -N 2 -A n /dev/urandom)%$(tput colors)))m.\e[0m"; done

Seth

12:55 AM

> set to highest brightness and tape to ceiling

Mateo

@hbdgaf yep

Zacharee1

Rebooting into Ubuntu to try...

hbdgaf

Nice. It's even skinned to bring the feel of that website with it.

Seth

haha that's pretty cool

Mateo

ooo, colorful lights, that is coool

took a bit of cpu ;)

Zacharee1

12:58 AM

meh

hbdgaf

If you polled /dev/random I would guess it would take less CPU. I don't think you need cryptographically sound randomness for blinking lights.

Seth

@hbdgaf you have a point lol.

Mateo

other news I need to learn to encode something in base64

Seth

well you're in luck

Mateo

> matching/ssh/c3No - Search results for the query 'ssh' (note that the final segment is a base64-encoding of the search query) - commandlinefu.com/site/api

Zacharee1

1:01 AM

@Mateo why?

Seth

@Mateo man base64 ftw!

Mateo

the search takes the search query + the same query encoded

Zacharee1

@Mateo I'm whelmed :p

Mateo

guess it stops random searching - requires someone to program that in

hbdgaf

@Seth improves upon a post on command-line-fu with minimal effort. feels accomplished or not

Mateo

1:05 AM

@Seth hmmm, don't suppose you know that in c++ ? ;)

hbdgaf

@Mateo karanbalkar.com/2014/02/…

Serg

@Mateo ok can you explain to this slightly tired slavic dude what youre ttrying to do there ?

Mateo

@hbdgaf nice, looks like that might do it - just have to smash it into my code somehow ;)

@Serg so, I'm making a ubuntu phone scope - and their search requires the search be encoded

hbdgaf

the to and from both take QStrings, and it's cleanly separated into a forward declaration and a function. the hardest part will be includes and the .pro file mods

Seth

@Mateo Use QByteArray.toBase64();

Zacharee1

1:09 AM

@Seth QBertArray* :p

Seth

bert o_O

Zacharee1

Cubert?

Seth

the example provided in the Qt docs looks like this:

  QByteArray text("Qt is great!");
  text.toBase64();        // returns "UXQgaXMgZ3JlYXQh"

Zacharee1

I haven't upgraded packages in Ubuntu for so long, I couldn't install Brackets :p

Mateo

oo, that might be even easier

hbdgaf

1:11 AM

Same thing. The extra lines are just the type conversion, because you probably already have the data as a QString

Serg

@Mateo and you're doing it in c++ exclusively ?

Nathan Osman

@Mateo What are you trying to do?

Mateo

Zacharee1

:)

86 packages to upgrade...

Mateo

well, they have qt stuff in there too, so that is cool

hbdgaf

1:12 AM

@Zacharee1 Feel lucky. I'm re-doing my upgrade from Win7 to Win10 for the 3rd time...

Mateo

oh my

Zacharee1

@hbdgaf sounds fun and why?

102 rep to go

hbdgaf

@Zacharee1 So I can give side by side comparisons of dual release games with frame rate/quality of gameplay on the exact same hardware.

Did I send the process to the background?

Nathan Osman

@Zacharee1 Yell, louder!

I knew I had sent it to BG, bug I had no idea how to get it back

@NathanOsman don't take credit, @Mateo saved me :p

Nathan Osman

Lol.

@Zacharee1 lol , you stopped the job. Fg brings it to foreground, aka resumes. Bg resumes in background

Zacharee1

Nathan Osman

Sends out rescue boat.

Rescue boat hits iceberg...

Zacharee1

@NathanOsman let's not take this where I think it's going

Nathan Osman

I guess we both die in this case.

Zacharee1

@hbdgaf and there it is...

Nathan Osman

Me in the boat, you because of my bad aim.

Serg

Hmmm, is there a signal to send a job to foreground ? Like kill -SIGSTOP

Zacharee1

How do I upgrade the headers?

Nathan Osman

Boats don't have headers.

I should just boot my laptop and see..... I'm so o o o lazy right now..... should be studying but . . . .lazy

@Mateo base64 can be done in Python too and seems like easily by tje way

Zacharee1

sudo apt-get dist-upgrade

thanks guys

Great. Now the chat's blocking me because I typed in caps

hbdgaf

Isn't linux-headers the metapackage that just maps to the currently installed kernel? Seems like it was at one time, so you just had to install it once and leave it alone.

Zacharee1

@hbdgaf it says those packages were held back from upgrade

so I did a dist-upgrade

hbdgaf

@Zacharee1 and it's not the caps it's the percentage of the ongoing conversation

Zacharee1

@hbdgaf Well then I guess I'll shut up for a while :p

Talk people, Talk

Mateo

1:24 AM

@Serg it's allways easier in python ;P

Serg

I might even Consider getting a pet snake now

Nathan Osman

@Mateo You had a Qt question?

Mateo

well, now I need to put a string into seth's code

Nathan Osman

Where is the code? Anything I can help with?

Zacharee1

@TheBrownOne how do you pronounce badinage? The vocab book puts the accent on the last syllable, but that makes no sense

Just did an autoremove, which almost never goes well

Mateo

1:27 AM

@NathanOsman sure

Zacharee1

Let's see what happens

Mateo

let me throw it into github

Nathan Osman

@Zacharee1 Those should in theory be harmless.

hbdgaf

Tell that to someone who went through the multiarch transition running wine and wine64 instances in different wine prefixes ;)

Zacharee1

Seems to have turned out fine

:D

Nathan Osman

1:30 AM

Faint explosion was heard.

Zacharee1

I really need that rolleyes emoji right now

Seth

no you don't :p

Serg

I am sooo about to pass out..... how do people have energy and stay focused and study and all that ?

Zacharee1

@Serg Wish I could tell you

Olumide

Can anyone please offer advise with this?
http://askubuntu.com/questions/726071/repairing-broken-installtion-from-live-usb-without-losing-data/726075

Zacharee1

1:35 AM

Is there really no way to install the GNOME Software Center in 15.10?

hbdgaf

@Olumide Just install without formatting, use a different username as the primary user, and your profile should stay in tact. Then you could probably (and I do mean probably) change the username in /etc/passwd and be fine for most things. Your group memberships will be wiped out though.

Seth

I highly suggest you make a backup first though.

hbdgaf

^^ that too -- I did say probably

Seth

yes you did. So the install leaves everything under /home though? I've heard that it does but never needed to test.

hbdgaf

Install without format should only overwrite, not purge. So, the different username should sort that bit. I'm operating on shoulds though - not known does.

People that cry that their ~/ was wiped probably installed with the same username...

Zacharee1

1:38 AM

/home is preserved, at least in the times I have had to reinstall

even with the same username

Problem is, it doesn't always fix boot problems

hbdgaf

Really? ?How did it handle the duplicate UIDs/name pairings?

Zacharee1

I don't know. You can just do some weird in-place upgrade

It's also handy if you aren't on the latest version of Ubuntu, since you can just do an actual upgrade

Serg

I usually wipe everything, nothing preserved. Didn't even get the option in installer

hbdgaf

On the linux side I always wipe or leapfrog LTS.

Nathan Osman

@Mateo ping me when you have it. Supper time now.

hbdgaf

1:42 AM

Wait, if windows were linux, would XP and 10 be the LTSes? rimshot

Seth

@Zacharee1 but is that a working install upgrade or a bad install overwrite?

Zacharee1

@hbdgaf XP and 7

Seth

the former should work fine since it shouldn't actually be re-installing the entire system, just updating system files.

Zacharee1

@Seth I have only gotten it to repair boot once or twice. I usually have to resort to backing up and reinstalling completely

Why?

Q: Renamed home folder, now I can't log in

I'm new to Ubuntu, and this is my first post on this site. I'm using Ubuntu 15.04. I was trying to change the name of my home folder. I right clicked the folder but the "Rename" option was grayed out. So I selected "Log in as administrator" (or something along those lines). Then I was able to r...

Serious misinformation there

Seth

@Zacharee1 you said it preserved your home when you upgraded. We're talking about a reinstall here and I think they operate differently. That's all.

Zacharee1

1:46 AM

@Seth If you choose to replace Ubuntu, yes, but if you choose Something Else... and choose the drive Ubuntu is on, I don't remember it overwriting /home then

I honestly wouldn't suggest doing it though, since it doesn't end up helping anything

@Mateo @ParanoidPanda will be mad when he sees the non-Imgur link :p

I was not aware of that app's existence

Seth

we don't talk about that app.

Zacharee1

Is it the IE of Ubuntu?

Seth

what happened to don't talk about it? :p

I guess you could call it the Edge of Ubuntu.

lol that sounds catchy now.

it's some leftover piece of unity 8 convergence that got pushed early, but doesn't exactly work.

Zacharee1

@Seth but Edge is good...

Seth

what language are you speaking?!

You can go up to 1.1billion colors on NVIDIA in Ubuntu...

@Zacharee1 yes.

because that's obviously how you restore your .bashrc to default.

@hbdgaf It really is fast, though

Nathan Osman

I'm going to try doing something for Drive.

Installing Unity 8 now...

Nathan Osman

Although... the emulator doesn't work properly on my system for some reason.

@Olumide "Try"

Zacharee1

2:25 AM

@NathanOsman Ubuntu scrub :p

The Aero Snap arrow keys work on GNOME? Wow

Mateo

worded something like "try ubuntu" or something like that

Or 15.10

the other option will say something like "install"

Long install

My answer had lots of probablies, so it's not an answer. It's how I think it should logically work. Listen to them, ^^ my mind is on something else.

Zacharee1

@hbdgaf I somehow read "probabilities" as "questions"

I need sleep

Mateo

just don't click on the install icon on the desktop after that ;)

Ok, I have a class mainWindow (based on Gtk.Window) containing an instance-scoped button named button (based on Gtk.Button), which on click triggers a method defined in mainWindow called create_update_window; create_update_window initialize an instance-scoped instance of a class updateWindow (based on Gtk.Window) and then calls (in this order) its methods 1)show_all() 2)update() (which in turn runs pkexec).

For the life of me, I can't figure out why the the instance-scoped updateWindow is shown only after update() is run:

#!/usr/bin/python3
from gi.repository import Gtk
import subprocess

class updateWindow(Gtk.Window):

	def __init__(self):
		Gtk.Window.__init__(self, title = "Updating...")

		self.label = Gtk.Label()
		self.label.set_text("Idling...")
		self.add(self.label)

	def update(self):
		self.label.set_text("Updating... Please wait.")
		subprocess.call(["/usr/bin/pkexec", "/usr/bin/apt-get", "update"])
		self.label.set_text("Updated.")
