2:00 PM

@Marco if you have any recommendations for that program/script, let me know. I do all my dev coding outside of the bzr... in github... in a private repo... :P

James Gifford

Morning @TheEvilPhoenix.

The Evil Phoenix

@JamesGifford mornin

James Gifford

@TheEvilPhoenix How're things?

Wait, don't answer that. just read back

The Evil Phoenix

:P

noticed the hyper rage mode level <crazynumber>? :P

its less right now, but its still hyper rage mode

James Gifford

I see.

The Evil Phoenix

2:06 PM

40 mins ago, by The Evil Phoenix

i'm amending it:

[ <standard rage level due to how much is on schedule> * (50000000 * <number of projects with an unfeasible due date>) * <Hours to work with MSoft software> * (6*<number of systems running Windows XP>) ] ^ <number of servers being evil> == hyper rage mode, level 500000000000000000000000000

pretty much sums it up

James Gifford

is scared of the burniator

Marco Ceppi

Maybe you shouldn't work with Windows machines then?

4

The Evil Phoenix

perhaps the State should stop working with Windows machines

its actually dependent on the number of servers at the server farm that are not working right

which is a big number

remove that, work with jsut this:

[ <standard rage level due to how much is on schedule> * (50000000 * <number of projects with an unfeasible due date>) * <Hours to work with MSoft software> * (6*<number of systems running Windows XP>) ]

and it ends up being rage mode 6

which isnt bad at all

because i'm usually around rage-2

:P

anyways, @Marco did you test 2.0 of that script? the PPAs were updated last night with the pushed changes

Marco Ceppi

Not yet

Writing long angry emails

The Evil Phoenix

heh

at whom and about what? :p

James Gifford

2:15 PM

I think I'm the subject of most of them. ;D

The Evil Phoenix

lol

James Gifford

We established this awhile ago - I founded the Cult Of Jorge, and therefore the Cult Of Marco hates me. lol.

The Evil Phoenix

lol

James Gifford

@Rinzwind Is the founding member of the cult of Jorge ;)

The Evil Phoenix

still lol

James Gifford

2:19 PM

Greg

@Takkat ping

The Evil Phoenix

darn i need more coffee COFFEE RUN!

Greg

I'm running through the steps at askubuntu.com/questions/16988/… and I'm stuck at the stage "Mount the USB drive to the installation environment". The USB disk is listed in the devices, but its menu item is disabled. Any help guys?

James Gifford

You need to enable virtual boxes access to the USB bus.

(How to do that, I don't know)

The Evil Phoenix

you need to manually define that

you need to know what the USB bus is on the host machine you've connected the device to

and specify that in the vbox config for that vm

but it sometimes fiails

James Gifford

2:26 PM

@Greg So yes, we know what we're doing, but we don't.

The Evil Phoenix

now...

if VBox actually wokred on this system

i'd start messing with it

but as it doesnt right now

meh

James Gifford

Likewise. I kinda bricked it with this thing called "Unity". (Made it slower than heck)

Oli

@Greg Quite simple - you need to add your user to a group (I forget it off the top of my head) to be allowed to hand off USB devices to vbox

Greg

@Oli ah makes sense... I'll Google

Oli

You want to add your user to the vboxusers group

The Evil Phoenix

2:28 PM

@JamesGifford HAH YOU NUKED YOUR SYSTEM WITH 11.04 FAILURE TO YOU!

htorque

hello chat!

The Evil Phoenix

@htorque go back to your nebula :P

James Gifford

@TheEvilPhoenix Uh-huh.

htorque

i'll give you a nebula

3

Oli

help.ubuntu.com/community/VirtualBox/USB

The Evil Phoenix

2:29 PM

@htorque i'm already in a nebula so :P

James Gifford

I love how the rest of us are too lazy to google it, and then @Oli does the hard work for us. :P

htorque

i don't think you got what kind of nebula i meant :P

The Evil Phoenix

@JamesGifford +1

@htorque i did. but i'm ignoring your intended statement :P

htorque

nobody can ignore that nebula :P

The Evil Phoenix

unless they dont exist in your space-time continuum :P

htorque

2:32 PM

you mean my space-i-got-no-time continuum

so, cya all :-)

The Evil Phoenix

now... i need someone to test this script on maverick... i tested on lucid and it works...

also tested on natty and it works...

James Gifford

@TheEvilPhoenix Give me an hour and I'll have my maverick VM booted.

Greg

Ah, just realised that when a group policy changes, the user has to log out then back in again to see the changes.

James Gifford

(give or take two hours)

The Evil Phoenix

@JamesGifford hehe OK

James Gifford

2:37 PM

In the meantime, send me a link to this script and tell me what it might (or might not) do!

The Evil Phoenix

pretty straightforward... streamlines manually grabbing a key from a keyserver and adding it to the apt keyring (so that PPAs, packages, etc. that are signed would work)

launchpad.net/~addgpg-apt-developers/+archive/ppa

that's the PPA

James Gifford

So is there any particular way to test it?

The Evil Phoenix

code is located in the bzr for the project: launchpad.net/addgpg-apt/2.0.0

yeah actually

the issue was it wouldnt access the keyring

Greg

@Oli where abouts in the UK are you from?

The Evil Phoenix

it would EOF out

so using either of my launchpad keys, you can test it. because i made its packages with my launchpad keys xD

@JamesGifford i just need to see if the EOF bug in this was fixed:

EOF error when adding gpg key to apt

[kahless]% addgpg-apt 5509C82E gpg: requesting key 5509C82E from hkp server keyserver.ubuntu.com gpg: key 5509C82E: "Thomas Ward (2nd Launchpad PGP Key) <email address hidden>" not changed gpg: Total number processed: 1 gpg: unchanged: 1 gpg: no writable keyring found: eof gpg: error reading `-': general error gpg: import from `-' failed: general error Above is error code. The error is triggered on a PGP key that is not utilized, but is a new key. Source of error: unknown.

addgpg-apt

Critical / Fix Released

@Marco was testing yesterday and confirmed the bug

James Gifford

2:41 PM

Ah. gotcha.

The Evil Phoenix

and late last night i finished fixing it

tested on lucid and natty

James Gifford

So I can use any PGP key?

The Evil Phoenix

but not maverick

yep

any PGP key

James Gifford

Yay!

The Evil Phoenix

because my vm for it imploded

on any keyserver... use addgpg-apt --keyserver <server> <PGP key id>

yes, i coded in the --keyserver part

James Gifford

2:42 PM

Crap. my 10.10 ISO is corrupt. downloads another one

The Evil Phoenix

LOL

Marco Ceppi

@TheEvilPhoenix Got a PGP key I can pull in?

James Gifford

Hey, it's not like they aren't there anymore!

The Evil Phoenix

by default it uses the ubuntu keyservers

@MarcoCeppi one sec

Marco Ceppi

Actually I have one to test with

The Evil Phoenix

2:44 PM

:P
@MarcoCeppi 4E279753

yet another one of mine

or you could pull the example keys from my keyserver...

if you absolutely want to... :P

i just need to make sure it doesnt EOF

Marco Ceppi

gpg: requesting key F909CE43 from hkp server keyserver.ubuntu.com
gpg: key F909CE43: public key "Marco Ceppi (Personal Marco Ceppi key) <marco.ceppi@seacrow.org>" imported
gpg: Total number processed: 1
gpg:               imported: 1  (RSA: 1)

worked

The Evil Phoenix

did it say OK at the end?

James Gifford

Does this mean I don't need to fire up my VM anymore? :'-(

Marco Ceppi

yes

just forgot to type in my password. Shouldn't it instead just run in sudo?

The Evil Phoenix

ah good

then it works

yeah, the apt-key part needs sudo

although it can be run as sudo

@Marco i ran into issues with that, strangely enough

it was having an issue saving the key as sudo... since its two separate commands that are needed to run for getting the key ready to import

onen to download, one to export as ascii armored. then that ascii armored pipes into sudo apt-key add -

Marco Ceppi

2:47 PM

Why not just have it fail out if $USER != 0 say "Need to run as sudo"

The Evil Phoenix

because it wasnt allowing the keys to be downloaded right when i tested

in the 1.0 series i ran into that

but i'm going to test later...

and fix that if possible

i try to avoid running my scripts as sudo :P

but i did ask how to find superuser or not before on stackoverflow for bash scripting

Oli

@Greg Born in Essex (but really, that's all), lived most of my life in Cambridgeshire, have been in Southampton for the past 3 years but am in the process of moving to Norfolk (I've made it as far as north-west-Suffolk so far, will make it all the way some time this month.

The Evil Phoenix

so maybe i'll incorporate that into the code...

Greg

@Oli I've stuck firmly in the Midlands all my life

The Evil Phoenix

@Marco given that my bandwidth is sort of limited here... i dont have access to my git repo nor do i have access to bzr to push test code

and i pushed README file updates from a different system yesterday so i need to update the local git stuff

Stefano Palazzo

2:52 PM

do you guys want to play with pythonfu.com?

The Evil Phoenix

whats pythonfu.com

Stefano Palazzo

well you need to find out :-D

88.130.94.244 ← pythonfu preview

I'm going to leave this running for some time, go nuts :-)

The Evil Phoenix

i do not trust IPs :P

Greg

OMG VIRUS

The Evil Phoenix

^ that

:P

lazyPower

2:54 PM

Nice @StefanoPalazzo

Stefano Palazzo

you can mess up the site if you want, try to break it :-)

and some feedback on the functionality and usability would be very much appreciated

The Evil Phoenix

@Stefano exec('rm -rf ./*') :P

Stefano Palazzo

@lazyPower thanks :-)

The Evil Phoenix

i actually did that...

in PHP

they said "Try and break my PHP install!"

so i broke their site :P

because they allowed exec() access

Greg

tut

Stefano Palazzo

2:57 PM

lol :)

The Evil Phoenix

but they asked me to so :P

Stefano Palazzo

by the way, I don't store any passwords like dropbox ;-) just hashes - sha1(sha512(password))

Greg

rainbow the hashtable!

Stefano Palazzo

When the site goes live, I will use something like 2^14 rounds of salted sha512, because I can

Greg

ask Chuck Norris to salt your sha512s, then if someone breaks them... etc.

The Evil Phoenix

2:59 PM

@StefanoPalazzo but what happens if the location the server is at gets bombarded by explosions? then you wont have anywhere to run the site :P

Stefano Palazzo

indeed :)

The Evil Phoenix

so at that point, you can't use 2^14 rounds of salted sha512

because there's no system to do it :p

Marco Ceppi

@StefanoPalazzo Looks great

James Gifford

@StefanoPalazzo Your passwords are salted, right?

Stefano Palazzo

thanks!

@JamesGifford not at the moment, no

James Gifford

3:04 PM

@StefanoPalazzo OK. glad he used a old password

Stefano Palazzo

@JamesGifford take a look at the hash snippet, it's just copied from the code of the site

James Gifford

@StefanoPalazzo 404 on user pages.

@StefanoPalazzo OK.

Stefano Palazzo

but it's easy enough to implement, and I'll do it before the site goes live

The Evil Phoenix

lol

Stefano Palazzo

@JamesGifford yep, much of the site just isn't implemented yet.

The Evil Phoenix

3:07 PM

@MarcoCeppi I originally had code for that... its amazing i forgot about it... and the question regarding it was my second asked question here:

23

Q: How can I determine whether a shellscript runs as root or not?

This is something I've been curious about. I make a lot of small bash scripts (.sh files) to do tasks that I routinely do. Some of those tasks require everything to be ran as superuser. I've been curious: Is it possible to, within the BASH script prior to everything being run, check if the sc...

that's where i got a majority of my rep :P

James Gifford

88.130.94.244/snippet/b48e75aa9edcceb22957ddf81b0186bc/…

Marco Ceppi

@StefanoPalazzo I think your snippet urls are too long. Maybe use a tiny URL engine to compute a smaller hash?

James Gifford

OOOHHHH.... Gravatar. nice.

Stefano Palazzo

@MarcoCeppi I was thinking I should give them sequential ids instead, like I do for users

couchdb doesn't have an "autoincrement" thing built in, so it's at the bottom of the todo-list ;-)

but tinyurls would be cool too, like s.pythonfu.com/32fa or something

Marco Ceppi

yeah

Kim

Stefano Palazzo

oh, that's not good

Kim

So, this group is for software engineer who write code for ubuntu?

Marco Ceppi

@Kim No, this is just a chat room for anyone/everyone that uses Ubuntu or Ask Ubuntu

Though we do have some people in here who write code.

Stefano Palazzo

@MarcoCeppi yikes! how embarrassing. I'll re-write the session code this evening :-(

I bet I forgot to copy a dictionary somewhere

Marco Ceppi

3:27 PM

Runs amock as James

Kim

@MarcoCeppi That means some of you work in the same company here?

Marco Ceppi

@Kim No, most of us have never met in real life.

Greg

following this tutorial askubuntu.com/questions/16988/… on installing ubuntu to a usb hdd, it almost completed, then complained that an error occurred when trying to install the boot loader, and I had to then choose dev/sda dev/sda1 dev/sda2 or dev/sda3, or skip installing a boot loader.

I skipped loading the boot loader, then the installer crashed

:\

Kim

@MacroCeppi How to get the authority to commit code to the ubuntu code base?

Marco Ceppi

@Kim Well. First you need to join launchpad then you need to sign the CoC, then you need to find a project, find a bug/feature request, write code, submit the patch to the team, they'll review and reject/approve it.

Then your code is in the project. If you want direct commit access to certain projects you'll need to apply at each individual project. Typically they only accept people who have been actively fixing bugs/building features

There is no "one Ubuntu code base" it's comprised of a large number of smaller projects.

The majority of those projects are hosted on LaunchPad

Kim

3:35 PM

@MacroCeppi what is CoC ?

Marco Ceppi

Amith kk

Hello all

@MarcoCeppi Im officially part of the arduino world :D

Kim

@MacroCeppi cool.

Marco Ceppi

It's pretty easy to get started. If you have no idea where to start this wiki page offers vast options

Kim

@MacroCeppi are all the projects on lunchpad open to any people to submit patches?

@MarcoCeppi Does kernel project open to people either?

Marco Ceppi

3:40 PM

@Kim Yes! Open Source projects thrive on people sending in patches. LaunchPad makes it easy for you to submit a patch to most bug reports

@Kim The Ubuntu Kernel is open source as well. I'm not sure how they do their patching since they use Git and not Bazaar for source control.

Kim

@MarcoCeppi like patches to customize linux kernel?

@MarcoCeppi Thanks really

@MacroCeppi very helpful

Marco Ceppi

@Kim Well, is currently patching the Ubuntu Linux kernel for customization, they typically won't incorporate customization that don't provide a benefit to the larger community. However, you're free to patch the kernel and compile it as much as you want.

The best way to get involved with Kernel hacking is to view the bug and security issues for the kernel and to join the Ubuntu-Kernel IRC room on freenode.net

hihi

The Evil Phoenix

i despise the internet today

ANYWAYS

lets see if i cant update my code...

@MarcoCeppi got a github account? I'd like to temporarily include you in the dev repo for that script

Kim

I have signed the CoC on launchpad, how can i submit code to the team of a project

and get my code reviewed by the team?

@MacroCeppi I have signed the CoC on launchpad, how can i submit code to the team of a project and get my code reviewed by the team?

The Evil Phoenix

@KIm what are ya trying to do

get code reviewed by a team?

Kim

5:26 PM

I'm trying to join a team

The Evil Phoenix

i'd start by creating your own lp branch: lp:~lpusername/projectname/branch

then point them to the code in that branch

that way its not in the project's branch, but they can review the code if they wish to import it

subsequently, contact the team's leader/driver

so they can review the code

because they'd be controlling acceptance

i've done this for teams i manage, so... :P

Kim

if accepted, they will let me join in the team?

The Evil Phoenix

or

@Kim up to the team leader

Kim

ok

The Evil Phoenix

as i said

talk to the team leader... they could take your code and use it, but not give you team membership.

granted they'd attribute that code modification to you in some form

but they are in no way obligated to give you access to their team

for instance

if @Marco wanted to be a member of the addgpg-apt developers team

i'd let them join

because @Marco helped confirm a bug, test the fix, and has recommended code changes.

but that's my team. LP policy states that i am not obligated to have anyone join my team

for any reason

Kim

5:30 PM

ok , thank you for your suggestion anyway.

The Evil Phoenix

its a strong suggestion. because only the team leader/manager knows the obligations needed to join a team

and out of my curiosity... what team are ya trying to join?

Kim

BHC

The Evil Phoenix

has no clue what BHC stands for

Kim

launchpad.net/bhc

actually, I want to join a small team.

The Evil Phoenix

yeah you'd have to talk to the team leader: Rudy

well... i'm not looking for team members

but i'm going to add marco-ceppi anyways

Kim

5:33 PM

:)

The Evil Phoenix

@Marco FYI, you're being added to the dev team for addgpg-apt for recognition of your assistance

:P

Marco Ceppi

@TheEvilPhoenix yeah, it's marcoceppi - ever since I made my own private git repo I rarely use the hub

The Evil Phoenix

:P

@Marco want to know what i found with trying to use sudo to run it?

addgpg-apt --keyserver keyserver.ubuntu.com 4E279753
You must be root to do this.
teward@kahless:~/addgpg-apt_dev_stuff/git/addgpg-apt-development-code$ sudo ./addgpg-apt --keyserver keyserver.ubuntu.com 4E279753
gpg: WARNING: unsafe ownership on configuration file `/home/teward/.gnupg/gpg.conf'

gpg: WARNING: unsafe ownership on configuration file `/home/teward/.gnupg/gpg.conf'

Marco Ceppi

Yeah, what happens?

The Evil Phoenix

that

Marco Ceppi

5:45 PM

interesting.

The Evil Phoenix

it wont run because its trying to pull from the executing user's gpg stuff

hence why apt-key should be run as sudo

and that's all

i ran into that in 1.0.3

which i never uploaded to lp

Marco Ceppi

I wonder if you could have it wrapped in sudo, but then drop to a user shell from inside of the script

The Evil Phoenix

not sure. that's a bash question :P

for now, 2.0 works and requires sudo for adding the apt-key

Marco Ceppi

sure, so it just prompts for the user password

easy enough

The Evil Phoenix

i might have it download the key...

but add in an echo before the apt-key stuff

saying "This script requires sudo privileges in order to add the key to the APT keyring. If you do not have sudo access, please press Ctrl + C now."

then they know why they see the sudo passcode

Marco Ceppi

5:48 PM

yeah, that would be best for the time being

The Evil Phoenix

i'll release that as 2.0.1

Alvar

hi all :P

paste.ubuntu.com/658073

@TheEvilPhoenix the codes in here will they be use in your script/program?

Kim

Is this enough to use bazzar ? "sudo apt-get install bzr"

Alvar

no one should work with windows machines!

@Kim why not sudo apt-get install bazzar?

The Evil Phoenix

@Alvar my script can get the keys for you, yes. use addgpg-apt <key> for the launchpad.net ppa ones

same for the ubuntu.com ones

for the playonlinux ones...

you'll need to know where they put their keys

it might not be a standard keyserver

Kim

5:51 PM

I work with windows at work

The Evil Phoenix

@Alvar in which case you'd have to specify that keyserver: addgpg-apt --keyserver <keyserver> <key>

Kim

and telnet to a unix server

Alvar

@Kim then I feel for you...

@TheEvilPhoenix too much work...

I rather just reinstall linux, it's easier :P

Or I just w8 for 11.10! :P

Marco Ceppi

@Alvar Install @TheEvilPhoenix script and use this:

Alvar

@MarcoCeppi use what? :)

Marco Ceppi

5:53 PM

sudo apt-get update | grep "NO_PUBKEY" | awk '{ system("addgpg-apt "$21) }'

That will fix most of those errors

The Evil Phoenix

@Marco FYI the script isnt made to run on every key

it'd have to go sequentially

it doesnt yet handle more than one key

Marco Ceppi

That's what my one liner does :)

The Evil Phoenix

:P

nice.

Marco Ceppi

Could use xargs but since we're already using awk - might as well just envoke it from system

Alvar

alvar@alvar:~$ sudo apt-get update | grep "NO_PUBKEY" | awk '{ system("addgpg-apt "$21) }

Marco Ceppi

5:55 PM

That might not work because of the sudo thing, but if it doesn't then I have an alternative

You missed a '

Try this instead:

5:56 PM

but make a note that the script wont check which keyservers to use

the keys must b e on the ubuntu.com keyservers

in order for addgpg-apt to get them without specifying keyservers

Marco Ceppi
