@TheX George Edison, Marco Ceppi and Stuart Langridge did launchpad.net/chromify-osd

TheX

@StefanoPalazzo thanks

Totty

now it works!

finally

with both off

TheX

@Totty good job at figuring it out :D

Stefano Palazzo

@Totty I made it an answer, so that others can benefit from it. You can accept it by clicking the green check mark next to it, so they know it worked for you.

Totty

now i got another problem

Stefano Palazzo

00:09

You should delete your first question, It's unanswerable now

Marco Ceppi

@RebeccaChernoff Ecstatic!

Totty

yes, i will do it;
anyway, I partitioned this hd of 320GB in 3 parts, 75GB 75GB and the rest. I would like to install the linux on the first one but i got this error: "no root file system please correct this from the partitioning menu"

TheX

@Totty are you sure you are not the problem??? I mean after all when it comes to me and computers. I am usually always the problem\

@Totty

what is on the first partition?

Totty

here look like: device: dev&sdb1, type: ext4

74999MB

TheX

why so many paritions, why not let UBUNTU handle the partitioning?

Totty

00:12

i would like to install linux on 75GB, win xp on the other 75GB and share files in the rest, no installation

TheX

you have to install xp first

or it won't work

but this is that I would do...

make your HD all one hard drive again

install xp

shrink it to 75

Totty

then leave xp, that i dont have it right now..

TheX

then format the remainder to ntfs

Totty

if i would install only the ubuntu how would i do?

TheX

let ubuntu install side-by-side, on the remaining HD space

and that will give you an option of drive space

if you want to only install ubuntu then you would select the option that says "use entire disk"

or something likie that

Totty

00:15

but i cant use partitions and still install ubuntu?

TheX

you can...

but you can only have 4 partitions...

you already have 3

and ubuntu needs at least 2

so that would put you at 5

got to go good luck

Totty

how ubuntu needs 2? it doesnt install on 1 partition?

Stefano Palazzo

Ubuntu doesn't need two, strictly speaking :)

@Totty how much ram do you have?

Totty

i dont understande nothing about this. 4GB

Stefano Palazzo

4 gigabytes is plenty, if you go to the manual paritioning thing, create a new one, select "ext4" as the file system and "/" as the mount point, you should be fine

If you had less memory, it would make sense to create something called a "swap parition", where applications can store data if you run out of memory

Totty

00:20

ok, perfect. with the "/" i will not get the error anymore?

Stefano Palazzo

what error?

sorry I was gone just now, just came back from making coffee (at night...)

Totty

no root file system please correct this from the partitioning menu

Stefano Palazzo

Oh, yeah. What ever is mounted at "/" is called the root file system

Totty

ok, thanks ;) now the laptop is hot, I have to wait to install. xDD

Totty

00:37

now i have to go, have a good night and thanks ;) see you!

Stefano Palazzo

you're welcome, bye

Rebecca Chernoff

02:04

@StefanoPalazzo, email just went out, sorry for the delay.

Stefano Palazzo

@Rebecca, never mind, I think it's a brilliant idea. plus your email didn't go to spam, and why would it ;-)

Rebecca Chernoff

shrugs happened to a few of the candidates in the first couple THCs

Shazzner

02:27

hey guys I need some help

I think I borked my install

ubuntu freezes when it loads up

doesn't even dump me to a console

windows boots fine though :/

I think it happened because I was messing around with drivers

*graphics drivers

if I can get to a console I think I can reinstall them

Stefano Palazzo

@Shazzner what exactly did you do? (warning in advance, I don't know all that much about graphics drivers)

Shazzner

I installed a ppa for the latest nvidia drivers

but I was having some weird glitches, so I manually installed them

*uninstalled

then I reboot and bam locked out

it just freezed at the 'ubuntu' screen (doesn't make it to the login) and I have to hard reset

I think, I could just reinstall ubuntu but I cannot lose my /home folder

but I have no clue on how to do that without formatting

anyway sorry for all this just a little p-o'ed

Stefano Palazzo

Can you boot into recovery mode?

Shazzner

...

you know I don't think I tried that!

Stefano Palazzo

While booting, hold the Shift key to see the Grub boot menu, then select what is probably the second entry, something like "Ubuntu bla bla (Recovery Mode)"

Shazzner

02:32

let me try that and I'll report back

yeah my grub works fine

ok brb

Stefano Palazzo

don't you want to know what to do when you're booted into recovery mode before you do it? (:

Shazzner

02:44

ok back

failed though unfortunately, for some reason my keyboard doesn't work in recovery mode

tried another one, same problem

Stefano Palazzo

huh

No idea how to diagnose that, you may want to ask a question about it

Shazzner

hrm

ok if I boot from a recovery cd, how do I unencrpyt my home folder?

*unencrypt

Stefano Palazzo

I think you have to create a new user, move your files over while being logged in as the original user, and delete the old one

there may be an easier way, but I haven't found it

again, ask a question on the site, that'll make it much easier (and also help out others with the same problem)

Shazzner

@StefanoPalazzo yeah

TheX

03:42

hello gang

George Edison

03:55

@TheX: Hello.

TheX

@GeorgeEdison hey just the guy i want to see...

George Edison

Oh?

TheX

can you tell me how to install chromify-osd again?

or not...

George Edison

I can.

First make sure you have my APT repository added.

TheX

which i don't, I just reinstalled ubuntu

because my other one broke

George Edison

04:04

Oh, I see.

Open the Ubuntu Software Center.

TheX

ok

George Edison

...then go to Edit->Software Sources.

TheX

ok

George Edison

Other Software tab.

Add...

deb http://apt.quickmediasolutions.com maverick main

^--- put that in the box

TheX

okay

George Edison

04:06

Now click OK to all of that and open a terminal.

sudo apt-get update

sudo apt-get install chromifyosd-plugin

TheX

ok

George Edison

I have to find the link for the Chrome extension here...

Okay... bazaar.launchpad.net/~chromify-osd-team/chromify-osd/trunk/…

Download each of the 3 files on that page.

TheX

ok

George Edison

When you're done, put 'chrome://extensions' in the URL bar.

...and hit Developer mode.

TheX

okay

George Edison

04:10

Then hit "Load unpacked extension..."

...and browse to the folder with the 3 files you downloaded.

TheX

ok

George Edison

Then hit Open and close ALL Chrome windows.

TheX

ok

George Edison

Then try it out by going to this page.

(Be sure to use an actual URL for image.)

It work?

TheX

not sure...

not done yet

I am waiting for some updates to install, I am putting your directions in a text file

George Edison

04:13

Oh, okay.

TheX

hmm I have to work tomorrow...

George Edison

I should put the instructions online :)

TheX

I will send you the text file

then you won't have to type them all again, just modify it to look like you want

if you would like...

no more ip4 addresses as of this morning...

George Edison

Where did you hear that?

TheX

news.yahoo.com/s/afp/20110203/ts_alt_afp/…

Stefano Palazzo

04:20

finally!

TheX

they will have to make the transition... maybe I will finally get a new modem... I have only had this one for 4 years now...

George Edison

> 'World IPv6 Day will start at 0001 GMT on June 8.'

TheX

i can't wait, we should have a virtual "World IPv6 Day Party"

Stefano Palazzo

It's not often you get to hear a supposed doomsday scenario come true and watch the consequences

TheX

@StefanoPalazzo it is not a doomsday...

because ISP still have banks of ipv4 addresses... they just can't get new ones...

Stefano Palazzo

04:23

No, you've misunderstood

TheX

so once they run out they have to transition to ipv6

Stefano Palazzo

IP addresses are the fabric of space, so the whole universe will turn into a massive black hole if there aren't any left

TheX

now if Ipv6 fails at some huge scale... then we could be doomed

Stefano Palazzo

If people turn out not to be ready for ipv6, they could just take back the massive blocks of addresses they gave to big companies in the early days

TheX

@StefanoPalazzo it isn't up to people being ready it is up to the ISP's being ready

Stefano Palazzo

04:25

yes, I know (people as in "the people whom it concerns")

TheX

oh got ya...

i thought you meant at a larger scale... people like you and i

Stefano Palazzo

doesn't PARC have a whole /8 or something like that?

and CERN too

I thought I'd read something like that

TheX

who?

Stefano Palazzo

parc is Xerox' palo alto research centre (the people who've invented the mouse and the gui), and cern is the place where the www was invented, they now host the large hadron collider

TheX

oh... yeah i have heard of both, just didn't know what they where called off the top of my head

Stefano Palazzo

04:30

Yeah, I sometimes forget how much of a nerd I am (:

TheX

you ever watch silicon valley?

good movie... not sure how factual it is though...

Stefano Palazzo

No, I haven't- never heard of it

TheX

oh sorry

I told you the wrong name

it is actually pirates of silicon valley

Stefano Palazzo

oh

TheX

Pirates of Silicon Valley

Pirates of Silicon Valley is a 1999 film based on the book Fire in the Valley: The Making of The Personal Computer by Paul Freiberger and Michael Swaine. It is a made-for-television docudrama written and directed by Martyn Burke which documents the rise of the home computer (personal computer) through the rivalry between Apple Computer and Microsoft. The film stars Anthony Michael Hall as Bill Gates and Noah Wyle as Steve Jobs. Plot In 1984, Steve Jobs (Noah Wyle) speaking to director Ridley Scott (J. G. Hertzler), who is in the process of creating the 1984 commercial for Apple Comput...

Stefano Palazzo

04:33

I saw that one

quite some time ago

I remember knowing that a bunch of stuff wasn't quite correct

TheX

right but it makes for a good movie :-P

Stefano Palazzo

Well I though it wasn't that good a movie either, but I know what you mean (:

TheX

you know... the original www had good intentions... it was to be free for everyone...

Stefano Palazzo

I'm just about to switch ISPs, and I imagine it's going to be an absolute nightmare

but free it ain't (:

TheX

@StefanoPalazzo good luck...

fortunately there is only one ISP here... so even if I wanted to switch, which I do, I can't

Stefano Palazzo

04:39

You can barely get anyone to sell you just an internet connection here. They'd all rather you bought a landline, a mobile and some television service as well. And they make you jump through hoops if you don't want to. I could rant about it for hours :P

Of course, no IPv6 either

DoR

I love Woz. He prints his own 2 dollar bills and spends them.

TheX

yeah we have that problem here too...

Kaustubh P

06:52

what does md5 /dev/urandom do?

George Edison

It takes a random value and computes the MD5 hash of it.

Kaustubh P

oops, lost my shell.

Stefano Palazzo

but only after an infinite amount of time

:)

/dev/urandom keeps on spewing out random bytes until the end of the universe, so, md5sum never finishes

George Edison

@Stefano: Actually, it will terminate - because md5 is not a command :P

Stefano Palazzo

Ah right!

Kaustubh P

06:56

I read that it doesnt terminate. It has to be killed. ON some systems, it stops.

Stefano Palazzo

@KaustubhP (assuming you meant "md5sum") it will only stop if something goes terribly wrong, like an out-of-memory condition or a stack overflow

try "man md5sum" (same for sha1sum, sha224sum, sha256sum, sha384sum, ...)

Kaustubh P

ahh, thats correct.

how to check system-wide resource limits?

in mac you would mayb do launctl limit

Kaustubh P

07:37

never mind, its ulimit.

htorque

good morning, everyone! why do i have a big red icon showing a "1" and linking to askubuntu.com/review/suggested-edits at the top of the page?

Kaustubh P

I have too.

jgbelacqua

@StefanoPalazzo optimist.

@htorque Have you guys acccepted edits before?

Just wondering if it is related to 2K+ or whatever users seeing edit requests. (I may be making the rep number up)

Kaustubh P

@jgbelacqua I cant accept edits, because they are not in my control. THey are just "edited" I am at 1100 rep.

jgbelacqua

Hrm. Well, there goes my theory.

htorque

07:46

maybe it's some 10k+ feature popping up for everyone?

Kaustubh P

My theory is that there is some maintenance going on.

jgbelacqua

I'm not seeing it.... So, not sure.

someone should upvote the first guy, so this goes out of the 'no answers' pool : askubuntu.com/questions/21059/how-do-you-install-packetfence

Stefano Palazzo

@jgbelacqua I just accepted a couple of yours

jgbelacqua

cool, thanks. Hope they are generally helpful.

Ah! Now I'm seeing the big red/orange circle.

Stefano Palazzo

yours are really good!

@jgbelacqua can you approver others' edits?

jgbelacqua

07:49

@stefano Cool -- thanks.

Kaustubh P

going to askubuntu.com/review shows a list of quesion that were maybe edite

jgbelacqua

No, I don't think I even see them.

Kaustubh P

maybe @jgbelacqua and @htorque had some answers or questions edited :?

Stefano Palazzo

Oh okay, i misunderstood you

this is what approving an edit looks like, I think you get +2 rep for it, no?

htorque

seems to be a 10k+ user feature

jgbelacqua

07:51

@stefano yeah, I wasn't sure what would happen with that, since I made an edit, then noticed I left an extra word in.

htorque

i couldn't access that page

jgbelacqua

and had to edit that, too

Stefano Palazzo

maybe (but I only saw very few since this feature was announced)

jgbelacqua

yeah, +2 rep. The interface is nice.

(I mean, that you posted -- I can't see it.)

Wow -- is it 10K?

Do we have 4 10K users yet?

Stefano Palazzo

It certainly doesn't say anything about suggested edits on the 10k page at /privileges

@jgbelacqua we have 3 right now, I estimate @DoR will be one in two weeks

htorque

07:54

well, askubuntu.com/review/suggested-edits directs me to page not found and there's only one feature for me to unlock - 10k mod tools

jgbelacqua

OK -- I remember someone was close.

Stefano Palazzo

he's at just under 9k, and gaining around 500 rep per week

jgbelacqua

Nice momentum.

Ok, my circle with the (1) disappeared again.

Maybe there was some accidental maintenance.

Stefano Palazzo

the reason for it has probably just disappeared

jgbelacqua

well, it was fun while it lasted.

Stefano Palazzo

08:00

You're going to get 2000 soon enough

(can't wait for it, personally; all your edits are excellent, and I'm looking forward to seeing more of them)

jgbelacqua

Thanks....

need more softball questions.

the boot/hardware stuff I'll leave to you :)

Stefano Palazzo

An easy way to get lots of rep is to ask great questions

well, it's not that easy :)

htorque

or do it like @JorgeCastro: ask great question and answer them yourself with great answers :D

Kaustubh P

@StefanoPalazzo because the great question have already been asked before :D

jgbelacqua

Ha -- yeah, I need a stockpile of those.

Kaustubh P

Stefano Palazzo

even better!

i totally did it the wrong way here:

Q: btrfs default file system for Natty?

Will btrfs be the default file system in Natty Narwhal?

Stefano Palazzo

When ever you find something cool, Ask a question about it and answer it yourself (if it hasn't been asked before). You even get the chance of finding a better way to do it

htorque

i should have cashed the 15 rep and THEN vote to close :D

Stefano Palazzo

hehe, that's devious (:

jgbelacqua

htorque

and your favorite places are the kitchen and the toilette? :D

oh noes, the (1) is there again

jgbelacqua

@htorque aaaaah! for some reason, this is really amusing me.

yep, still goes nowhere.

(or goes nowhere again)

Stefano Palazzo

Should be gone now

is it?

jgbelacqua

Yep, it's gone.

Seems the editing system is not kinkless.

Maybe make a post on meta about it

htorque

still love this one:

Stefano Palazzo

ha awesome!

jgbelacqua

@htorque ha

Stefano Palazzo

I don't even understand the notation :)

I know it's probably geometry, that's it. I'm not ashamed to admit (:

Kaustubh P

08:44

@StefanoPalazzo Thats Differential Calculus :D Geometry is related to shapes and algebra with equations.

The function when solved will give slope of a tangent at the point x=2pi

Stefano Palazzo

I see

I only knew that theta was used for angles, thats why I guessed geometry (and the notation sort of looked like a derivation)

Kaustubh P

wikipedia will do a better job of explaining. I am scratchy on Math now :P

Stefano Palazzo

If that's the slope of a tangent, wouldn't that be a really weird way of writing it down?

htorque

hm, i've never seen it written that way - ϑ/ϑx f(x)

Stefano Palazzo

It's probably testament to the fact that this was generated by a computer. It may be correct, but it's not right (:

htorque

08:52

my main problem with that thing: why is it 'ϑ' and not 'd' - there's only x

Kaustubh P

@StefanoPalazzo I dont knowwhat to say :/ I am sorry :( Oh, it might be incorrect, but we are jusdt discussing diff calculus :)

@htorque the ϑ stands for partial differentiation..

htorque

i know, but why?

Kaustubh P

Its not a theta, its a ∂

htorque

oh, what did i use?

stupid blurry small font

i need to get rid of my CRT monitor

Kaustubh P

ϑ in this case is (5.x - pi/2)

htorque

08:54

it's dark and blurry

i don't understand why it's used - i mean, it's f(x) with only one variable

Kaustubh P

The function represents partial diffrentiatio of x, keeping y constant.

htorque

which y :D

Kaustubh P

we do not know, because we do not have the complete function, i think.

my head hurts. I guess my head doesnt store 5 year old archives.

Stefano Palazzo

:)

htorque

well, i have to do partial differentiation from time to time, but i never need to actually calculate anything :D

Kaustubh P

09:00

Math was never my thang! I love Chemistry!

htorque

go away with chem! :D

Kaustubh P

Give me valency and Normality anytime in college!

htorque

you can produce good drugs and bombs with chem. knowledge :D

it's "breaking bad" vs. "macgyver" :D

Kaustubh P

ha!

09:05

Yesterday I performed an automatic security update suggested by the update manager on my virtualized (with VirtualBox on a Windows 7 host) Ubuntu 10.10 installation.

The update somehow failed and left me with an unbootable system. When I try to boot, I am told that various folders, files, and what not are missing. Then the system drops into a busybox and leaves me with an (initramfs) prompt.

This happens with all kernels I get offered by GRUB, although the error messages are quite different from kernel to kernel.

htorque

no, that's not unheard of in Windows-land

so, you do get grub showing the menu?

chessweb

yes, a grub menu with three kernels.

htorque

@chessweb at that (initramfs) prompt, can you mount your root partition? mount /dev/sda1 /

@chessweb here you go: help.ubuntu.com/community/Grub2#Reinstalling%20GRUB%202 - follow method 3, points 1. - 7. then run the two commands from above

@chessweb i forgot, you can omit the 'sudo' in the commands as you will be logged in as root
