Ask Ubuntu General Room

Oli

00:11

Well that was less painful than I had feared it might be.

George Edison

Oh, good.

Oli

00:39

And I'm finally done. Chrome is a paranoid POS when it comes to userscripts.

George Edison

00:54

We're ready to begin?

Oli

Yeah just testing my Chrome edits haven't broken Firefox.

George Edison

01:10

Don't forget that a lot of Ubuntu users use Opera :)

...but if it works in Chrome and FF, it probably works in Opera.

Oli

I'm not spending another hour catering to another browser. Not at this stage. Opera can burn in a fire. I've no idea why people choose a closed source browser when the open alternatives are as good as they are.

George Edison

Well... a lot of people use IE and that's far more worthy of a fire-burning.

That's closed-source at its worst.

Oli

Yeah but they don't go out of their way to choose that. Most just stick with what they're given.

Oli

01:29

Right, email sent @GeorgeEdison

George Edison

K. Test in progress!

@Oli I sent a suggestion... kind of minor though.

@Oli cheers to that!

Q: Recover files in Ubuntu from USB stick

I have Ubuntu 11.04 running from a USB stick. I think I ran some updates in terminal and now it has a kernel panic during boot up. Is there a way I can get hold of files I saved when Ubuntu was working? I just managed to watch the booot screen and it looks as if there are some errors saying ther...

can I get another upvote on users solution plz?

George Edison

@Oli: I found a much more serious bug and sent another email :)

Oli

@GeorgeEdison Yeah that's Chrome's fault for making me import another copy of Jquery. Working on it now.

lazyPower

@BrunoPereira i'd like to see more data in the post rather than a link thats probably going to 404 at some point in the future.

George Edison

@Oli You don't need jQuery at all on Chrome.

The site always has jQuery loaded by time your UserScript is injected.

Bruno Pereira

@Oli oh wow, this is fun!

Oli

@GeorgeEdison But how does it communicate with it? unsafeWindow doesn't exist and window seems to block it (based on my earlier hackings)

That's what I was originally doing for Firefox - just pulling in the SE copy of Ask Ubuntu by reference to $

It's weird that it only affects flag. Perhaps I should target that rather than trying to rewrite it all over again

Q: My laptop freezes after enabling extra visual effects

lazyPower

@GeorgeEdison what version of qtcreator are you using in Ubuntu 11.10?

Oli

02:15

@GeorgeEdison almost fixed it (flagging etc work but the textarea is chucking out an error, probably something to do with me loading another jQ)

Bruno Pereira

02:34

@Oli scores should be updated every 30 mins right? Is that part not functional yet?

Oli

@BrunoPereira They should be updating unless there's a horrible bug in the code. I'll run a manual update now and see what happens.

Bruno Pereira

@oli let me know when done

Oli

It's running now.

Bruno Pereira

did not do it automatic, did the work now

this is solved, can we get a upvote on any of the answers to see it gone for ever? askubuntu.com/questions/62086/…

@lazyPower I'm using Qt Creator on Windows these days :) I forget the version.

@Oli Why do you need jQuery?

The Ask Ubuntu pages already embed jQuery.

Bruno Pereira

You've earned the "Revival" badge for Recover files in Ubuntu from USB stick. See your profile. More badges! Thx @Oli :)

Oli

Mainly because I'm lazy and don't fancy coding my own JSONP decoder.
Yeah, as I said, I can't talk to the page's copy of jQ from a userscript in Chrome. You can in Firefox - that worked great.

George Edison

JSONP isn't 'decoded'... it's actual JavaScript source.

lazyPower

right, JSON is an actual javascript object by definition

Oli

@GeorgeEdison Yeah I really just mean writing the garb around it. I guess it wouldn't be too hard but I think I'm almost there fixing things. Firefox is the only problem now so I'm just going to add a shortcut back in to just use the direct copy of jQ

lazyPower

02:58

haha, hack on top of a hack. hi5 Oli. i do that too then regret it five months down the road when i re-visit the source.

Oli

@lazyPower It's actually not quite as bad as it sounds. It also speeds things up for FF users so that's nice.

No clue.

@AmithKK Everyone must still be sleeping off all that tryptophan from the Thanksgiving turkey...

Amith KK

Hey @GeorgeEdison

I wonder how Turkey tastes

Ah, now I have to get 7 euros for just a ubuntu pen?

No Fair

WarriorIng64

@AmithKK You haven't had turkey? I'd say it's like chicken, but drier.

Amith KK

@WarriorIng64 Is Thanksgiving a Religion or state based festival?

I'm Hindu and I live in India

WarriorIng64

04:06

Ah, okay...well, Wikipedia seems to have a general guide to Thanksgiving (I'm from the USA).

It's not really a religious holiday, but more national...something having to do with the pilgrims landing at Plymouth Rock and surviving in the New World with the help of the Native Americans or something like that

Wow...I just realized how much I've forgotten from primary school 0.o

Actually, this is more specific to the USA's version of Thanksgiving: http://en.wikipedia.org/wiki/Thanksgiving_(United_States))

George Edison

Yes, Thanksgiving is a religious holiday.

Amith KK

How do i change the time zone after installation of ubuntu server

@GeorgeEdison Cool

George Edison

Amith KK

@GeorgeEdison You know C++?

WarriorIng64

@GeorgeEdison Is it? Aside from the pilgrims, I didn't see any connection to a particular religion

George Edison

04:10

@AmithKK Yes.

@WarriorIng64 The pilgrims instituted it.

Amith KK

@GeorgeEdison There is no India

George Edison

@AmithKK There isn't?

It was on the map last time I checked :P

WarriorIng64

Amith KK

@GeorgeEdison On the time zone list

George Edison

No clue.

Amith KK

04:12

@GeorgeEdison Do you know Embedded C?

(You do own an arduino.. so you would)

George Edison

@AmithKK Not necessarily... the Arduino executes machine code so it doesn't matter what language I write "sketches" in as long as the output is binary machine code.

Amith KK

heh

George Edison

...and the compiler that Arduino encourages everyone to use is extremely similar to C++.

Not C.

Amith KK

Did you see my LCDCAM

@GeorgeEdison Noted!

@GeorgeEdison amith.dyndns-ip.com and amith.dyndns-ip.com/image.jpeg

are you there?

I tried something.

Amith KK

no, unicode wont work fully

Amith KK

@Oli LOL :) Im mounting it

George Edison

It isn't working.

I'm entering text, but it won't display.

Amith KK

mount complete... script resumed

George Edison

Aha!

Now it works. Neat!

Amith KK

04:41

Both @GeorgeEdison and @MarcoCeppi can replicate this

George Edison

What happens when more text than can be displayed is received?

Amith KK

It gets cut

I could make it autoscroll

ut that would be complicated

Considering the somewhat small memory on the atmega

Python would have to query the memory and send the text b2b

George Edison

It didn't like my carriage return and linefeed :)

Amith KK

It autowraps

George Edison

Lol.. that didn't work.

Amith KK

04:45

and the good part is, you can write another client side program using the var ?textToShow=<input>

@GeorgeEdison You use the dollar system?

George Edison

The "dollar" system?

Are you asking what currency we use?

We use the Canadian dollar.

Okay.

Amith KK

How can I make all user's have a /var/www/<username> dir(automatically)

Oli

@GeorgeEdison Well you were right. Rather than doing real work as I'm supposed to I've been refactoring and refactoring my userscript code and now it's shorter than the original, doesn't need an extra copy of jquery, doesn't need hacks or special GM garbage... and seems to just work.

Amith KK

Hi @MarcoCeppi

How can I make all user's have a /var/www/<username> dir(automatically)

Marco Ceppi

@AmithKK You'll need to edit the adduser/useradd function

Amith KK

@MarcoCeppi And can I make it do so that other users cant access another users dir?

Oli

05:13

I suppose you could write a FUSE filesystem that knows where to look.

Amith KK

@Oli I can write a what?

Oli

A FUSE filesystem. It's a quick way to make a fake filesystem that behaves in a custom way on top of an existing, standard one, using whatever language you like.

For... an Apache setup?

Amith KK

Yes

How can i find out the IP?

George Edison

Is this a virtual machine?

Amith KK

yes

George Edison

Then it doesn't have an external IP address.

The only way to access services on it is to map guest ports to host ports.

Amith KK

05:44

Done

so, this would work: ssh amith@localhost -p 7070

George Edison

Where are you entering that?

In the host or guest?

Amith KK

On the host

and seems that the vm cannot access the outside network

George Edison

Can the host ping any external IP addresses?

Amith KK

@GeorgeEdison yes

George Edison

Then what's the problem?

Amith KK

05:47

the guest cannot access any external ip's

George Edison

Example port configuration -----^

Amith KK

@GeorgeEdison Did that

George Edison

What that does is map the guest port 22 (ssh) to the host port 8022.

Is the guest's network interface up?

Amith KK

I already binded 22 to 7070

@GeorgeEdison Huh?

George Edison

@AmithKK Is the guest connected to VirtualBox's network adapter?

Amith KK

05:50

@GeorgeEdison Yep, its NAT

(Soory I'm n00bish, Im very new to getting a server working on a VM)

George Edison

So can you ping your host machine's external IP address?

Amith KK

No connect:Network is unreachable

George Edison

Ah, so your guest can't see the network.

Amith KK

yes

George Edison

Well that's the problem then.

Amith KK

05:53

@GeorgeEdison Fix??

George Edison

Try the ifconfig command.

Amith KK

Oh yeah, I remember, I did not do a DHCP config during install

@GeorgeEdison there is lo

George Edison

Is there eth0?

Amith KK

no

George Edison

I believe lo is the loopback interface.

@AmithKK Then that's the problem.

Does your VM have the X server packages installed?

Amith KK

05:56

@GeorgeEdison I installed from the Server Disc

Interesting! Thanks for the update @GeorgeEdison (regarding the MinGW vs MS C++ headers)

George Edison

@lazyPower No problem.

It's interesting to know.

lazyPower

well its always bugged me that certain headers are cool cross platform where as some are not. Posix systems seem to be very strict on what they include and where.

George Edison

Yeah, so I guess the ideal scenario is that you're developing on a POSIX-compliant system and then just testing on others later.

...but 'ideal' != 'reality' :)

lazyPower

haha :) well i was using code supplied by the book vendor since my lab is to modify the simple hash table into a behemoth of added bells and whistles

it did not compute that the supplied source was not compiling, however since it was written in VS 2005, it makes sense that g++ hated it.

Q: I can't enable extra effects in Ubuntu 10.10. Please help?

I installed Ubuntu 10.10 alongside Ubuntu 11.10 to use an older version of Compiz. On Ubuntu 11.10, Compiz was enabled by default and I didn't need to use any graphics driver to enjoy the effects. All I had to do was install CompizConfig Settings Manager and enable those extra effects. That was C...

lazyPower

@jasoncruz98 did the restricted drivers manager not find the card?

user26781

@lazyPower all I got from the additional drivers was the same driver I installed on Ubuntu 11.10

lazyPower

sounds to me like it defaulted to the intel integrated gfx driver, which is a 'failsafe' type display module. You need to get whatever the restricted-drivers-manager detects your card as. That will add OpenGL support and allow you to enable desktop effects.

Interesting. Not sure whats going on then, unless there are some patches that were made to 11.10 that have not been backported to 10.10

user26781

I didn't want to download it because I am scared it would go to 2D, which I am already using now.

user26781

09:13

@lazyPower should I install the driver anyway?

lazyPower

if 10.10 is using 2d only, you havent lost anything by swapping the display module...

worst case scenario, the video fails to work and you spend a few hours scouring resources and curse my name for suggesting you try it

user26781

I didn't install the driver yet.

user26781

In Ubuntu 11.10 it went to 2D after installing the driver.
