Afternoon @lazyPower

Marco Ceppi

Hello World

Stefano Palazzo

A: Is it "safe" to try out Firefox 4?

If you Install Firefox 4, rather than upgrading to it, it's completely safe to try out. You can just download their Linux binary package, extract it and run Firefox from there*. With absolutely no risk to your existing Firefox installation. There are a bunch of methods of testing Firefox 4, for...

Any idea why I got a down-vote on this one

Marco Ceppi

@StefanoPalazzo Not sure

Stefano Palazzo

My assertion that it's completely safe is correct though isn't it?

lazyPower

@StefanoPalazzo I've only had one crash with FF4 and that was due to memory limits of my netbook not the browser code.

@StefanoPalazzo so I would say its fairly safe

@MarcoCeppi You're familiar with JQuery correct?

Marco Ceppi

16:30

@lazyPower Sadly, yes

Stefano Palazzo

Even if it does crash, it's still perfectly safe regarding the other components

lazyPower

if i pastebin something can you take a peek and tell me why its not working?

Marco Ceppi

Sure

@lazyPower Put it in Gist so you can see my changes (if any)

Oli

FF4 lags for me. Huge CPU spikes occasionally... And even without spikes, it can be really slow to change/close tabs Probably extension-caused because it was pretty nippy before I reinstalled them but I don't have that many extensions to be fair (firebug+webdeveloper+adblock)

lazyPower

Sending it as a DM on twitter

sent

@MarcoCeppi: Note the ID's have been altered to read ct100_ i'm not sure why but ASP is appending that to all the ID's.

Stefano Palazzo

16:33

@Oli maybe somebody misunderstood me, though I was saying that firefox 4 will run perfectly, when I was just saying that it won't be dangerous in any way. In any case, I'll clarify it

Marco Ceppi

@lazyPower Your problem is - I don't think you can capture click functions in the body. Code would have to be in the header

lazyPower

ah, so you cant display that inline?

Oli

@StefanoPalazzo I'm not commenting about your answer.. I'm just having a moan.

Marco Ceppi

Yeah, you can embed JS in the body - but not when it's capturing click events IIRC

let me do a quick check

Stefano Palazzo

I see

lazyPower

16:38

@MarcoCeppi: if thats the case its still not working :/

Marco Ceppi

@lazyPower I'm wrong, you can!

lazyPower

using the hash denotes using ID's, so i have zero idea why this isnt functioning :|

Marco Ceppi

Anything in the Javascript Error console?

TheX

what is this?

Stefano Palazzo

I just noticed someone voted all the answers and the question down, probably don't need to worry about it then

TheX

16:40

Stefano Palazzo

@TheX you can set a key to quickly switch layouts

lazyPower

Actually yes... in VS. When i include the official JQuery lib its throwing an error about .localScroll methods. :|

TheX

I never change layouts...

Stefano Palazzo

what packages are you installing?

TheX

I am doing updates

Stefano Palazzo

16:42

Is there any harmless selection available? (like None, or a key no never hit?)

TheX

Yeah I selected non I think

Stefano Palazzo

Don't worry about it then. Go to System → Preferences → Keyboard → Layouts to check if everything is in order

TheX

uh oh, i think synaptic died

Marco Ceppi

@lazyPower I didn't get the snippet number

I can't seem to push my changes back up

lazyPower

errr

/me is confused

TheX

16:45

what do I do now?

Marco Ceppi

It's an anonymous gist - I didn't realize that you didn't have a Github account

lazyPower

i do i just didnt login

:P

TheX

nothing, okay great...

Marco Ceppi

@lazyPower I forked it

I won't paste it here?

lazyPower

i saw, already looking at it

Marco Ceppi

16:46

Nice!

If that dosen't work I have one more idea

lazyPower

DIdnt work, it raised the event on page load

Marco Ceppi

Okay, one more idea

TheX

E: Could not get lock /var/lib/dpkg/lock - open (11: Resource temporarily unavailable)
E: Unable to lock the administration directory (/var/lib/dpkg/), is another process using it?

what is the fix?

Jorge Castro

don't run more than one package manager at a time

Marco Ceppi

@lazyPower pushed

TheX

16:51

@JorgeCastro I'm not

Jorge Castro

maybe the update manager is checking for updates?

TheX

nope

should jockey-gtk be running?

I figured it out

lazyPower

@MarcoCeppi: i think i've discovered the issue. They are using a trimmed set of JQuery >.>

So instead of giving me the full framework I have a limited set of methods I can use

well wait, fadeout has been in since 1.0, and u'm using 1.3.2.min.js

@MarcoCeppi: yep they are using sizzlejs cssselector. this isnt pure jquery

fml

Jorge Castro

@MarcoCeppi woo! death to ubuntu-desktop tag!

Marco Ceppi

@JorgeCastro Yeah, Jeff picked up the message in the teacher's room

lazyPower

17:02

@MarcoCeppi: thanks for the code snippet audit anyway :)

Marco Ceppi

@lazyPower No problem, if you need me to look over anything else just put it in a Gist :D

TheX

first I tried to set the house on fire, and now I can't get my computer to work

lazyPower

Hurray for ASP Fail! worldcitiesdatabase.com

TheX

there is nothing wrong with the .net framework....

except everything....

lazyPower

it makes me want to punch babies

TheX

17:13

@lazyPower wow...

lazyPower

I was all about it until I had to develop with it.

TheX

let me guess you are never going to have kids

lazyPower

then i got a taste of what its really about

I'm actually dating a girl with two kids...

TheX

then she should either take the kids far away and never let you around them... or never let you around computers...

lazyPower

I'm getting interested in ruby. I just havent had time to really investigate it.

bbl lunch time

TheX

17:16

I can not install nvidia drivers for the life of me :(

lazyPower

17:53

mmm CHicago Style deep dish pizza om nom nom

TheX

@lazyPower are you from Chicago?

lazyPower

Origionally from KC MO, currently living in Pittsburgh PA

TheX

oh, you just like Chicago Style Pizza then?

lazyPower

yep

Windy City Pizza is amazing

TheX

I have been to chicago a few times... the pizza up there is great

lazyPower

17:57

Indeed it is

One of the Gems of the midwest

TheX

we live about 3.5 hours from Chicago, don't go there very often... can't afford it... lol

KC has some good food too though... plus the Negro League Baseball Hall of Fame...

or whatever they call it

lazyPower

i havent been home in a while. Last time I was back i was down south in the Springfield area visiting my parents

TheX

Pittsburgh has the Steelers puke

lazyPower

Dont hate because we are on our way to seven ;)

TheX

not because "you" are on your way to 7

but because my brother is obsessed with them and will not shut up if they win

lazyPower

18:04

/me smirks

Its a Steeler Nation baby.

TheX

he lives in Indiana

lazyPower

Exactly why i say its a steeler nation. Steeler fans are everywhere

TheX

ugh...

Jorge Castro

@TheX Please see meta: meta.askubuntu.com/questions/871/…

your last 2 questions are too localized

TheX

fine goes and cries in the corner

lazyPower

18:20

@TheX having issues installing nvidia drivers with the restricted driver manager?

TheX

@lazyPower no i fixed that... now it is chrome

lazyPower

ah ok

TheX

chrome is crazy!

lazyPower

18:33

Chrome pwnz your socks

Aviral Dasgupta

18:49

Hi.

Anyone there?

Marco Ceppi

Hi, yes @AviralDasgupta we are here

Aviral Dasgupta

After upgrading to a new Linux kernel version

@MarcoCeppi I have new entries in my grub boot screen (for the new versions and the old ones)

is it safe to remove the old kernel headers, files, etc. via synaptic/aptitude?

Marco Ceppi

@AviralDasgupta Yes it is. Typically they recommend you leave at least one other kernel version - but that's up to you.

I would simply run sudo apt-get autoremove it should be picked up in there

Aviral Dasgupta

@MarcoCeppi nmm... nothing there

Reading package lists... Done
Building dependency tree
Reading state information... Done
0 upgraded, 0 newly installed, 0 to remove and 0 not upgraded.

Marco Ceppi

In that case, yes you can remove by just sudo apt-get remove and the exact linux kernel

Aviral Dasgupta

18:54

Sure :)

Thanks

Marco Ceppi

What version of Ubuntu are you using?

Aviral Dasgupta

10.10

@MarcoCeppi ?

Marco Ceppi

That's fine - I was just curious :)

Aviral Dasgupta

Oh

Anyway, it's on a netbook, so I'm trying to:

1. Fix up those extra entries (which you helped me with)

Jorge Castro

if you remove the packages it'll autofix the entries

I remove everyone except like the last 2 newest ones

Aviral Dasgupta

19:01

2. Reduce boot time (mucking about with ureadahead and bootchart), will post results later

(I mean isn't Ubuntu supposed to take substantially less time than Windows to boot up?)

Marco Ceppi

@AviralDasgupta Good luck!

@JorgeCastro Yeah, that's what we ended up doing

Aviral Dasgupta

3. (I need some help with this)

Marco Ceppi

Some of your questions you might want to place on the main site so all can benefit from it.

Aviral Dasgupta

The netbook in question is a Lenovo S10-3S

Marco Ceppi

Typically people will ask the question on the main site then come here to discuss it out

Aviral Dasgupta

19:03

@MarcoCeppi sure, but this one's too specific

Marco Ceppi

@AviralDasgupta Whatchya got?

Aviral Dasgupta

anyway, Lenovo has this thing called Quick Start which lets you boot up a quick and dirty linux based OS, splashtop (boots in <5s)

as and when Google Chrome OS is released, I want to try replacing that with Google Chromium OS or Jolicloud

Now, the only "problem" I have ... is that

you can boot into "Quick Start" mode using a special button on the display

and I want (whichever OS I pick) to boot when that's pressed (like splashtop)

@MarcoCeppi That's not very Ubuntu related, is it?

Marco Ceppi

@AviralDasgupta No, it's an interesting question though. I don't have a Quick Start enabled netbook (Because I don't have a netbook) but I would be interested to see if that was possible

Aviral Dasgupta

@MarcoCeppi I poked around a bit, and it looks like there's no external (separate partition) installation, so I guess it's installed in a manner similar to wubi... also, I have no idea how booting using that button "changes things". Would be good if I did...

Marco Ceppi

@AviralDasgupta It might actually be in or around the bios or on it's own SSD

Aviral Dasgupta

19:11

@MarcoCeppi Then, it wouldn't be possible to swap, right? (btw. I'm pretty sure that it doesn't have an SSD)

@MarcoCeppi Also, it's offered as a separate download (installer) from their website.

lazyPower

@MarcoCeppi your smart book hasnt arrived yet?

Marco Ceppi

@lazyPower No, back-ordered

lazyPower

Bogus... Thanks CES.... :|

@MarcoCeppi i was wrong yet again, they have the 1.4.x JQuery lib included as well.. i'm lost on why this isnt working... and my project lead isnt answering :|

Marco Ceppi

Sorry I'm a little upset because I accidentally destroyed my slinky

lazyPower

I hate it when that happens.

TheX

19:21

@MarcoCeppi video or it didn't happen

Marco Ceppi

TheX

so how did it happen?

Marco Ceppi

It got tangled

and I kept trying to get it untangled

and destroyed it in the process

TheX

Yeah yeah, that sucks

lazyPower

19:43

@MarcoCeppi: 4ea9723e951e90d6fcf

Marco Ceppi

:)

lazyPower

if you can puzzle it out, i'll give you a cookie man. I'm banging my head off the desk left and right now

Marco Ceppi

I get a 404

lazyPower

add a 0 on the end

had to let you play with the 3d 404 page :P

Marco Ceppi

@lazyPower HTML5 fun :)

What's not working? Same issue?

lazyPower

19:47

yeah its just not doing jack.

I can include the libs if you want

Marco Ceppi

ehhhhhh, maybe. Let me take a peak first

Is the code in JQuery block inside of LeadHandler?

lazyPower

yeah, thats what i'm trying to accomplish

just hiding the div elements

declaring them as classes, ID's is not working

Marco Ceppi

So is that in the LeadHandler.js file?

lazyPower

si

i have the LeadHandler.js posted as well as the MasterPage

Marco Ceppi

Okay, two problems

You going to use ID, or Class?

lazyPower

19:51

ID

Marco Ceppi

Try that

lazyPower

uhh all you did was add a nbsp?

Marco Ceppi

Nope, all I did was remove the <script> tags

lazyPower

No dice

in IE or Chrome

htorque

which revision control software should i use for simple text documents? svn, git, bazaar?

lazyPower

19:55

@htorque i'm a fan of Git

Marco Ceppi

Post the library and the rendered HTML output please :)

@htorque +1 on @lazyPower Git FTW

But it's really up to whatever you are most comfortable with

htorque

it's really just writing a text document, so no fancy features needed

Marco Ceppi

So, whatever is easiest and you're most familiar with :D

kzh

@htorque use mercurial

dv3500ea

@htorque what are you using to write the document?

LyX has version control built in

htorque

19:59

definitely not lyx

dv3500ea

although you have to install an extra package

htorque

:D

i'm not sure yet, probably kile

lazyPower

e60f911b98ab0b51b469

Jorge Castro

dropbox. :)

lazyPower

dropbox is a great solution as well

kzh

20:01

Dropbox is nice.

dv3500ea

I'd probably use bzr then. Definitely not svn.

badp

dropbox only if you're working solo

Marco Ceppi

CVS?

lazyPower

@dv3500ea personal vendetta against svn?

Jorge Castro

oh, I assumed solo when he said simple text files

htorque

20:02

nah, i'd don't like to put it somewhere online

yeah, solo

badp

No, I meant "only one person writes it"

Dropbox has no conflict management

htorque

the only conflict's i'm going to have are the ones with myself :D

badp

then dropbox is fine.

dv3500ea

@lazyPower no but as far as I know, you need to commit to some kind of server

htorque

cvs/svn is server-client

kzh

20:03

You can collaborate with a dropbox folder.

lazyPower

some svn clients support local repositories.

kzh

dropbox.com/share

lazyPower

eg: tortoiseSVN

kzh

or TortoiseHg

dv3500ea

bzr and git you just keep everything local then push to a server if necessary

lazyPower

20:04

i repeat: i'm a fan of git ;)

kzh

same with mercurial.

htorque

yeah, distributed would be fine

kzh

I'm a fan of mercurial.

Mercurial is distributed.

htorque

guess i'll toss a coin for git/bzr

dv3500ea

I have no clue about git vs bzr vs hg

kzh

20:05

gitvsmercurial.com

htorque

i never used mercurial before :-(

Marco Ceppi

@kzh +1

htorque

well, what's wrong with getting input from experienced users?

Marco Ceppi

@htorque because it's a squabble fest

kzh

I love that site, almost as awesome as howfuckedismydatabase.com .

htorque

20:08

i'm not asking, if emacs or vim is better :D

kzh

VIM!!!

Marco Ceppi

Nano, Pico

lazyPower

@MarcoCeppi you see'ing what i'm seeing?

htorque

lol, nice

kzh

Can I flag that as offensive?

Marco Ceppi

20:10

@lazyPower No?

lazyPower

@MarcoCeppi it keeps appending ct*_$id to the elements....

Marco Ceppi

Not everything though. Which is interesting

lazyPower

1

Q: .Net Changes the element IDs

Hi, .Net is kindly changing the element ids on my pages by appending a ct100_ to them. As much as I appreciate microsoft trying to help me keep from duplicating ids on my site, I think I can manage it on my own. Can anyone tell me how to prevent this? Thanks in advance.

asp.net

known issue. nice.

dv3500ea

What just happened? A number 2 just appeared over my avatar and asked me if something was spam when I clicked on it.

It has now disappeared.

Jorge Castro

cool

4

A: How can I make sure one Upstart job starts before other Upstart jobs?

The solution is to approach the problem from the other direction: to satisfy the start criteria for Centrify, it is not necessary to make existing services depend on the new Centrify service, rather make the new Centrify service depend on existing services. For example, an Upstart configuration ...

the new upstart guy is already answering questions!

lazyPower

20:17

@dv3500ea on chat?

dv3500ea

@lazyPower yes. The number was blue not red like normal when someone @pings you.

lazyPower

interesting....

Marco Ceppi

@dv3500ea Yeah, it happened to me. You're a 10k chat user

You get those blue mod messages too

dv3500ea

Oh I see.

so was that something someone flagged as spam in chat?

Marco Ceppi

@JorgeCastro You should tell him to register his account

@dv3500ea Yeah it was in another room - someone said "to hell" and someone got offended by it

lazyPower

20:21

@MarcoCeppi i suppose thats not hte issue though, as its not prepending to the <div's> i'm trying to modify with JQuery

Marco Ceppi

@lazyPower yeah. Is it live that I can test in my browser and run firebug against it?

lazyPower

no, just on my ASP dev server run off localhost

Marco Ceppi

Ah, gotchya

lazyPower

hang on let me portforward it

Marco Ceppi

Sweet

lazyPower

20:26

nevermind its denying all connections that dont origionate from localhost

htorque

alias kamikaze='sudo apt-get update && sudo apt-get dist-upgrade -y' - at least now i know why banshee is gone :P

lazyPower

haha nice @htorque

htorque

E: Broken packages => broken heart :..(

:D

the power of diversity: banshee uninstallable? so what, i'll start rhythmbox.

lazyPower

@MarcoCeppi i know why it didnt work now

@MarcoCeppi the div elements were not rendered yet so it couldnt hide something that did not exist. D'OH!

moving that script into an inline <script> tag below those elements worked.

Marco Ceppi

@lazyPower Weird, I guess there is some other tom-folery going on that is causing the script in the head to be executed prior to the loading of the dom

lazyPower

20:33

You saw the source, so you KNOW thats a fact.

sifting through this hodge-podge mashup of .Net, JQuery, and VB has given me googley eyes

Marco Ceppi

I noticed that there is a "span" HTML tag that's being rendered inside of the <head> for the Google Analytics which might be what's casuing that

that span tag should be injected at the bottom of the DOM in order to gather proper statistics, PS

lazyPower

I'm not seeing it

hold on

found it, thanks.

Theres several of them

egads

TheX

any web page experts?

Marco Ceppi

21:01

@TheX Sure, I'm pretty knowledgeable

TheX

@MarcoCeppi cool just curious

Election Markup Language

Election Markup Language (EML) is an XML-based standard to support end to end management of election processes. History of EML The OASIS Election and Voter Services Technical Committee, which met for the first time in May 2001, was chartered "To develop a standard for the structured interchange of data among hardware, software, and service providers who engage in any aspect of providing election or voter services to public or private organizations. The services performed for such elections include but are not limited to voter role/membership maintenance (new voter registration, membership...

We should get stackexchange to make launchpad links get expanded like e.g. wikipedia (see the faq)

Jorge Castro

@nealmcb paste in a bug report. :)

@GrizzLy yes, absolutely, the more the merrier!

GrizzLy

@jor

@JorgeCastro ok tnx :)

nealmcb

@GrizzLy you can edit a previous post for 120 seconds - see the faq

Jorge Castro

scifi.stackexchange.com

can you guys see that one?

I think it went public today

nealmcb

22:39

@JorgeCastro Yup. Are you one of the founders?

Jorge Castro

I signed up and committed, so I was in the private beta

area51.stackexchange.com/proposals/22748/…

this is the one I hope to found ^^^

nealmcb

I just missed the private beta for security.stackexchange.com

But I've been having a good time there anyway

Marco Ceppi

@nealmcb I'm not quite sure. I've heard about the project on and off and just now found out it's mostly open source with Git feeding their VCS

nealmcb

@JorgeCastro which project?

Marco Ceppi

Cool, SciFi is in public beta

nealmcb

22:45

@MarcoCeppi Oops - I replied to Jorge by mistake. Now I get it.... Yeah, OLPC is great, even with some wobbles along the way. Fantastic hardware price/performance.

Jorge Castro

YOU SHOULD UPBOAT ME! scifi.stackexchange.com/questions/743/…

nealmcb

@JorgeCastro still 80 seconds to edit this to give us more clue

:)

Jorge Castro

what a brilliant question, I must say. giggles

@nealmcb I'm on guitars.se too

but I am there only to learn, so really I do is vote a bunch

Marco Ceppi

@nealmcb Yeah, I'm just now discovering their reach. So I'm going to see what I can possibly contribute to them
