wisemonkey

lol can we comment with "WTF" and similar?

jrg

You can, it's just not recommended. :)

wisemonkey

ohh

well I won't just the first think that came to my mind ;)

rlemon

wow... even his github is full of trolls.

github.com/prtk/random_codes/blob/master/password_grabber.js

jrg

@rlemon what is this?!

rlemon

00:06

the time machine user - i went to his blog (eww) and he has a link to his github account - full of trolls.

TROLLS!!!! TROLLS I TELL YOU TROLLS!

Thomas Ward

TROLLS?

jrg

TROLLS

Thomas Ward

Trolls who must be hunted down, placed under arrest, and then beamed out into space so that they cease to exist?

there would be a nice series in no time

rlemon

bwahahaha

wisemonkey

and who is the password grabber?? :-o

Thomas Ward

@rlemon no, Writing Perl is not a waste of time... COMPILING Perl is a waste of time :P

rlemon

the guy who asked about the time machines

Thomas Ward

since the compilation takes longer

rlemon

@ThomasWard Wow! late grabber

lol

no, writing perl is a waste of time.

Thomas Ward

00:13

my motto: If its in the starred list, its eligible to be responded to at any time :P

rlemon

so is ASP

Thomas Ward

so is Microsoft in general

WHAT NOW DUDE?!?

rlemon

ah.. didn't even notice it was starred

Thomas Ward

:P

wisemonkey

@rlemon: don't they clean github? :P

rlemon

00:14

i agree... MS is a waste of time.

@wisemonkey apparently not. surf around long enough and you feel like you're back in geocities.

Q: Can't download web photo albums to Picasa

Someone has shared a Picasa web album (Limited, anyone with the link), but I can't download it to Picasa. The following alert appears: Firefox doesn't know how to open this address, because the protocol (picasa) isn't associated with any program. I have Picasa 3.0.0 installed on Ubuntu 11...

can anyone answer?

George Edison

@MarcoCeppi: Are you around?

I've run into a design problem with my charm.

Marco Ceppi

Go for it

George Edison

The charm ships with a CLI installer (it's a PHP web app).

I need to figure out where to invoke the installer.

Marco Ceppi

I'm familiar with status.net

Where, or when?

George Edison

Ah, perfect.

@MarcoCeppi When I guess - the installer needs the config and DB data to be available.

Marco Ceppi

00:56

the config is always available via the default

George Edison

Right, but not the relation data.

(For the database.)

Marco Ceppi

the installer should run after you have all the database details in db-relation-changed

George Edison

Hmm... I suppose that would work.

Thanks. I'll try that and ping you if I run into trouble.

Marco Ceppi

that's how the phpMyAdmin charm works

user=`relation-get user`
password=`relation-get password`
host=`relation-get private-address`
database=`relation-get database`
if [ -z "$host" ] || [ -z "$user" ]; then
        juju-log "Waiting for complete setup"
        exit 0
fi

...


mysql -h $host -u $user --password=$password $database < /var/www/phpmyadmin/scripts/create_tables.sql

# Generate configuration file!
build_cfg

George Edison

@MarcoCeppi Oh wait... some of the config data doesn't have defaults.

Like the admin credentials.

Marco Ceppi

00:59

That's fine, do you need admin creds for install?

George Edison

Yes.

Marco Ceppi

Okay, you can do this. In db-relation-joined do a check for admin creds (config-get is available in all the hooks) if it's not simply touch db-available

Then in config-changed do a check for db-available, if it is have it call an install function that's available in both hooks

that way, in relation-joined, if those admin configs are available then you can just run the install then

does that make sense? then when the install is done just touch installed in the charm dir

WarriorIng64

Hey guys! Installing 12.04 on my desktop now! :D

Marco Ceppi

to prevent it from going nuts and trying to install multiple times

@GeorgeEdison does that make sense?

jrg

@WarriorIng64 I'm jealous. :P

WarriorIng64

01:04

@jrg You may not have to be (depending on how this goes)

jrg

@WarriorIng64 heh.

George Edison

@MarcoCeppi touch just creates a file right?

WarriorIng64

Right off the bat, the installer found both 11.10 and 11.04, but doesn't provide the option to upgrade one of them...could that be a bug?

Marco Ceppi

Yeah, so you can do if [ -f ] at that point for checks

George Edison

Right. I was already doing something like that for ThinkUp:

echo "" > db_created

But I guess touch is simpler?

Marco Ceppi

01:06

mm, touch is basically the same thing

yeah, cleaner

George Edison

@MarcoCeppi What happens when the config data is entered after the db relation hook runs?

Wouldn't the DB config data need to be stashed away somewhere?

Marco Ceppi

relation-get is always available, just like config-get

George Edison

It is? I didn't know that.

Marco Ceppi

Zookeeper just triggers hooks when there is a state change, but the data is always there

George Edison

How does it know which relation to pull data from?

Marco Ceppi

01:09

Uh, good question

Maybe relation-get isn't global like config-get

jrg

@WarriorIng64 what are you going to do with this one?

WarriorIng64

@jrg You mean the installation procedure, or what I'm doing with 12.04 overall?

Marco Ceppi

@GeorgeEdison scratch that, you can just write that data to a file :)

I do it in the phpmyadmin charm in order to rebuild config files over and over again

jrg

@WarriorIng64 installation.

George Edison

01:11

@MarcoCeppi Ah, okay.

wisemonkey

anyone? and sorry if u all saw the question already

WarriorIng64

@jrg I'm thinking I'm going to specify partitions manually and tell it to overwrite my 11.04 partition. I'm still keeping 11.10 for stability and sanity.

jrg

@WarriorIng64 Hm. sounds like a plan.

WarriorIng64

So now I'm now in Ubiquity's manual partitioner, and trying to figure out which partition's which...

jrg

I've learned to write those down before I start partitioning, after i deleted /home and windows on accident... :P

WarriorIng64

01:16

jrg

(two separate occasions)

WarriorIng64

sda7 and sda5 look like swap to me (not sure why I have two...)

Not sure on the others

Er, wait

The drop-down list at the bottom says sda1 is 11.04, and sda6 is 11.10

jrg

wait, the dropdown list tells you that stuff?!

WarriorIng64

So can I just pick sda1 and go?

@jrg Yep...it shouldn't?

jrg

i never knew it told you that stuff.

WarriorIng64

01:19

lol...I just don't know if that's where I actually install the OS to, or if that's only for the bootloader

Doesn't say anything about sda5 or 7 though...probably just swap

Does 11.10 need to know if sda5 or sda7 is its swap partition? I'm currently thinking I should format sda1 and one of those two, then specify sda1 as / and one of those two as swap after formatting

jrg

not sure....

i haven't tried stuff like that.

WarriorIng64

The question is just which one...lol, it's one heck of a coin flip

jrg

Heh, yeah it is.

WarriorIng64

Guess I better do some reading

Argh, all I keep getting while searching while searching Google is people asking about manual partitioning for a first-time dual-boot between Ubuntu and Windows. Am I really the only one who dual-boots Ubuntu with itself?

jrg

I used to quad boot Ubuntu

U+1 (at the time, 11.10), LTS, 10.10, 11.04

WarriorIng64

01:34

Maybe I should just tell it to format 11.04, set that up as root, and let it figure the rest out on its own

jrg

Hm.

i should sell redis as a service.

WarriorIng64

Or not...just got my first crash, yay :D

jrg

get a little VPS in the cloud, and charge $5 to use it. james haz ideas

@WarriorIng64 report the bug!

WarriorIng64

This image is at least a few days out of date...should I?

jrg

yes.

if it's a duplicate,

it'll tell you as much.

WarriorIng64

01:37

lol, I didn't even install it yet! ...easily duplicatable enough, reporting. :)

...or not...?

Golden rule of testing bugs: you can always duplicate it except when you want to

Let me restart the installer and try again...

Hmm...the mount point in the partition settings comes up as an empty drop-down menu

And now it's just a blank window

Something tells me I should reboot and start over

Unless...

This is really crazy: I'm going to delete my /dev/sda1 partition in GParted, then restart Ubiquity and hope it sees the change

Ah, yes, it sees it. So here's what I noticed: if you have 11.04 and 11.10 both installed, it won't give you an upgrade option. But, if you only have 11.10 installed, then it offers that choice

jrg

hmmm... interesting.

WarriorIng64

01:52

At any rate, it's letting me install 12.04 alongside 11.10 now without further partitioning work apparently, so onwards

Haha, the "Choose a picture" screen in 11.10's installer was one of the biggest lies..."This picture will identify you in the account settings, login screen, and lock screen." Except it didn't. I wonder if 12.04's any different...

"Welcome to Ubuntu 11.10" I know that's not actually a big issue, but it's still a little funny.

jrg

@WarriorIng64 odd....

worked here. well, except in the login screen.

WarriorIng64

It'd be nice if the login screen pictures made it back in at some point. I miss them...

wisemonkey

hmm I've login screen picture

WarriorIng64

@wisemonkey In LightDM?

wisemonkey

background right? or u meant user pics?

yes

WarriorIng64

02:02

I meant user picture

wisemonkey

ohh then nope

just looked in this tab and only saw pictures on login screen :P

WarriorIng64

Wow, installation finished fast...scary fast!

I'm going to restart now and see what havoc I've wrought

wisemonkey

missed something?

WarriorIng64

Possibly...I got lazy at the partitioning step, and Ubiquity wasn't in the mood to help :P

brb

Marco Ceppi

Ugh, left like 12 juju servers deployed for the last two days

jrg

02:06

how much ram did it end up using? :P

wisemonkey

@WarriorIng64: u may already have tried it, crowd-greeter?

WarriorIng64

Well, I survived :D

Running 12.04 now...I lost my GRUB menu again due to a certain bug, but that should still be easy enough to work around. I can now update the status on that

Haha, Additional Drivers came up...I just look through and say "Nope, Nouveau's good enough". The blank-windows bug in 11.04 was the last straw for me, and I've never looked back

Wait forever for Software Center to start up, so I can load this thing up with the usual junk...

So from what I understand, 12.04 right now is basically 11.10 with updated packages, right?

anyone porting stackapps.com/questions/912/… to *nix?

George Edison

It's a .Net app (that uses the XNA framework), so it will never make it to Linux.

However, I started something similar: launchpad.net/stack3d

wisemonkey

damn looked pretty neat (not sure about functionality)

George Edison

It never got anywhere though.

lets hope somebody come along or hope that one day I can code :P

George Edison

You can try what I have written though.

It comes with a Makefile so compiling it should be simple.

wisemonkey

ohh yea I can compile will give it a try

so just download the tar.gz of trunk and give it a try?

George Edison

@wisemonkey Yeah, but you will also need:

sudo apt-get install libirrlicht-dev

(It uses the Irrlicht 3D library).

wisemonkey

ok

George Edison

Please let me know how it works.

Oh, come to think of it...

I think you also need my SE API C++ library too.

wisemonkey

07:37

I'll see if I hit any errors will keep on adding packages

George Edison

launchpad.net/sopp

wisemonkey

and yes will let u know

George Edison

^--- You'll need to make and sudo make install that project too.

wisemonkey

o.O and I was thinking to sleep after trying it

I guess I'll keep this for tomorrow :P adding it to - todo and have tabs open :)

I'll give u feedback
