I have never submitted anyone :(

When I found one, I tell to @Seth

Nathan Osman

Submit it here: gemsfromstackexchange.tumblr.com

Lucio

Do I need a tumblr account?

Nathan Osman

@Lucio: Nope.

Lucio

I see

A caption needed

I'm not good at this

Braiam

@Lucio where was that?

Lucio

SO

@Braiam Have you ever submitted something?

I don't want to use my real mail

Braiam

mm... no... I always use @Seth for that... he so too much spam that he don't care anymore...

Lucio

00:32

Me too :D

@Seth Give me your email!

:P

user320

hi how much space do i need for the root partitions on an install. and i i do too much can i change it later?

Lucio

like ~4G is enough

user320

what are you basing this off

do programms get installed into the root folder?

or do they go in the home folder?

Lucio

In previous docs that I've read

Braiam

@Lucio found where... and found Oli too :S

Lucio

00:35

There is a directory structure in every GNU/Linux system

@Braiam @Oli answer is the best

Braiam

@user320 why you want to know?

Lucio

see you later!

user320

hi

i am trying to install ubunut on my ssd

its only 120gb

Braiam

if you don't know use your entire drive for / so you don't have to change it latter...

Lucio

@user320 That is great!

user320

00:36

120gb for root? that can't be right

Lucio

If you want to install only Ubuntu, though

For the whole Ubuntu syst

user320

thanks lucio

but I am far from getting it installed right

Lucio

I have less than 40Gb used and more than 1 year using it

Cya!

user320

I need 3 partitions for linux right?

Braiam

why you think so?

user320

00:37

root, home , swap

Braiam

why you think you need root and home appart?

user320

i can have them in one?

Braiam

of course...

user320

cool

sorry i am new

Lucio

> Your submission has been received and is awaiting moderator approval.

user320

00:38

I use ext4 for that right?

Braiam

@user320 why don't just let installer decide, there is a option that reads "use all my hard drive" or something like that no?

user320

nope

its confused becuase i have win 7 on the other hdd

I want my ssd to have root&home, swap and then i made space on my hdd for files for ubuntu

Q: Installing ubuntu to a specific disk drive alongside Windows 7 on separate disk

I have deleted an entire disk drive (120 GB ssd) for ubuntu to be installed on. However, when I install ubuntu 13.04 from DVD, it never prompts me as to which disk drive to install on. Unfortunately, something is failing at the very end, so I have no idea where ubuntu is trying to install, but ...

user320

That thread was of little help to me

Seth

@Braiam Emm.. what? I don't care about what anymore?

user320

00:46

swap is harddrive ram right?

incase i run out of regular ram

Seth

@Lucio @Braiam I just get @FEichinger to post them to the gems... I don't like giving my email out and such. And he has a tumblr account.

@user320 Yes

Braiam

if you have +4GB of ram and you don't use too many applications at the same time, and or don't need hibernation swap is meaningless

user320

i got 12 gb of system ram

i have a lot of apps open though

in windows many times i hit the limit and it stated to dump to swap

Seth

Wow. Hitting 12 GB of RAM is hard.

I've never used more than 4 or 5, except once.

Braiam

I have 1.5 GB of ram right now and most of it is used for write/read cache...

user320

00:51

i use a lot of 3d apps

thats i want to switch to linux

win took 3gb of ram always no matter if i had nothing open

Seth

@user320 I have that issue too.

Windows apps ♥ RAM

Braiam

@user320 bottom line, if you don't know, just use a single partition for all, I wouldn't recommend using swap on the ssd disk, thats all

user320

so swap on an hdd is better,?

do i even need swap. what happens if i hit 12 gb?

Braiam

linux start OOM killer and start killing the most hungry apps, just that...

Seth

I would get some swap.

user320

00:59

but on the hdd right

Seth

Maybe 6GB. Depending if you want to hibernate.

user320

i never hibernate

Seth

@user320 yes

user320

so let me get this straight i can have home and root all on my ssd

swap on my hhd

and then more home on my hdd

home is just genreic files righ, like videos, etc.

Braiam

are you planning downloading the world in your home? Just store stuff in windows partition and left your home empty

Seth

01:01

@user320 yes

user320

thanks seth

setting up swap i easy i got that how do i create home and root both on my ssd what are the settings like ext4, etc.

do you guys like the unity look?

Braiam

do we really need this tag? askubuntu.com/questions/tagged/hardware-enablement-stack

I see that this question answers what it is askubuntu.com/q/248914/169736 but we really need questions to have a tag like that?

Seth

@user320 It depends. Are you doing a fresh install?

user320

my ssd is new my hdd has windows 7 on it, i want to keep it

i want my ubuntu to work technically without the hdd

Seth

You would arrange the partitions during the install then.

user320

01:16

yeah its quite hard though

Seth

I recommend launching a live session and then install from there.

user320

I tired that I get confused with the partitions

Seth

@user320 No, not really. I've never used a separate /home before, but root and swap are easy.

user320

root os for boot right and home is for files where do programm like chrome get installe on?

Seth

@user320 No.

Home is just for personal files

The Chrome binary would be located on / (root)

user320

01:19

swap is not necassary right?

if i take my hdd out one day and my ssd no longer has acces to it it alls good right?

Seth

It should be.

Unless the OS gets confused because the swap drive is gone.

user320

shouldn't happend anyway

but root is where programms get installed right?

Seth

Yes

Usually in /usr/bin I think.

But it depends.

user320

okay and do you know what the settings might be for the partition?

Seth

What kind of settings?

And which partition?

user320

01:31

i gtg will you be on tmrrw morning(10 hours from now?)

Seth

@user320 Emm... I don't think so.

1 hour ago, by Braiam

do we really need this tag? http://askubuntu.com/questions/tagged/hardware-enablement-stack

Seth

Well "too minor" was the wrong reason then.

Braiam

Nope, too minor if I don't believe that the edit is worth of being done whenever the post could be further improved or that the improvement is too small that it is of no worth.

Seth

If it's an improvement how can it be of no worth?

You leave the editor going "what did I miss here??"

Braiam

Because is too minor, it won't improve anything of importance. (and yeah I like recursion puns)

you won't ask what something means and add a tag that explain what it means... for that you read the tag

Seth

Emmm.

Braiam

Q: how to install Kali Linux without cd and flash drive

i was download kali linux. but size is too large for my flashdrive, my flash drive is 1.8gb and the kali linux iso is 2.3gb. i used asus eeepc 1215p where ther is no cd/dvd room. my machine was installed with ubuntu 12.04.3, and i have empty partition. i want to install kali linux into that parti...

ubuntu kali-linux

Alaa

@Takkat, sorry, this is in bash =D.

Basically, this is what I want to do:

if grep -q '/var/log/audit/audit.log' "$RSYSCONF"; then
continue
else
echo "[ERROR] Something went wrong with adding the configuration to $RSYSCONF. Quiting script."
exit
fi

But it doesn't work, because "continue" is for loops.

Is there a way to "skip" the true condition?

Achu

Sketched my report using wireframesketcher and hit save.

`This copy of WireframeSketcher is unlicensed, so you cannot save your work.` WHAT???

Takkat

07:21

@Alaa if ! grep -q '/var/log/audit/audit.log' "$RSYSCONF"; then echo $ERROR

Alaa

@Takkat yeah I want to do that, but according to the comments to this answer, I shouldn't.

Oh wait, but it's okay to run it without [ ]?

Takkat

@Alaa hmm - I did not get what they mean with flip... :/

Alaa

Because the if statement does something if it's true, and does something if it's false.

So instead of using a !, just flip the actions.

Takkat

Yeah, so it's if conditions; then run code; else error

Alaa

Yeah, the answer is if ! conditions; then error; else run code.

So they're telling him you don't need to use !, and just flip error with run code instead.

Anyways, let me try this out!

Takkat

07:30

Which should be the same, but you may have several else conditions to make things more mature in the sense of debugging woes.

<-- thinks that code should run, not look beautiful but that's a spare time coder's view ;)

Alaa

Yeah it's the same, I guess the comment is trying to say that it's just a bit more confusing if you're using if ! conditions when you can just use if conditions.

LOL yeah.

Awesome. It works. Danke!

Takkat

Code that works is better than code that runs but does not do what it should.

<-- did not start his new project because of lack of time for debugging nights

Alaa

Actually, the worst kind of code is the one that runs but does not do what it should.

I'd rather it spits out an error than go mess something up.

Takkat

It generally spits out an error after it messed up things :D

Alaa

Haha yup.

Takkat

07:40

I so much look forward to never ending long winter nights when people sit in front of their fireplace and I sit in front of my buggy code.

Once I get it all sorted out they will change the API I was using.

Alaa

For some reason, that reminded me of Breaking Bad's last aired episode.

Hey is there some kind of awesome program that "goes through" your code to check if something is wrong?

Like, missing parenthesis, wrong variable names

Takkat

it's me manually testing all possible variants of usage. I always forget the most obvious.

Alaa

Like, if it finds you typed $MYVR when there's no variable declared that's called that.

Yeah variants of usage is okay, but syntax could be done using a program =/, it would definitely save some time.

Takkat

I code in Python because the interpreter always tells me what I missed.

Alaa

Oh okay. I wish nano in gnome-terminal did the same thing =D.

Anyways, I need to get back to my rookie, first ever bash script.

See ya around.

Takkat

07:44

Some ~~years~~ decades ago I tried with C but had to give up because my apps always made my computer crash.

Then booting took ages.

Mahesh

08:28

@Alaa use vim.

Mine does syntax highlighting, error highlighting as you type for most cases, and suggestions on best practices and messed up logic.

with plugins, of course, but its the best IDE I have.

also has attribute and variable name completions and a documentation in a split window while tabbing through suggestions.

user320

12:13

hi

anyone able to help me with an install?

fossfreedom

12:27

@user320 sure - fire away.

user320

i have on hhd for windows 7 with about 300 free space i made for linux. I also have a new ssd i want to install the home and root on

basically hdd get swap and extra home and ssd get root and promary home

fossfreedom

ok - so the issue you have is?

user320

what is is?

I am not sure how to set up the partitions right

fossfreedom

so the ssd is plugged in and currently windows 7 sees it as a second drive - correct?

user320

becuase in the nd i will have 3 total: --1-root&home(ssd)--2-swap(hdd)--3-more home(hdd)

*end

my hdd is 1.5tb 1200GB for windows nd 300 for the swap and extra home

fossfreedom

12:37

@user320 root and boot should be on the SSD - swap can be either. Home should be on the hdd.

Braiam

@user320 why didn't you did what Seth and I said?

fossfreedom

? so this is an ongoing saga @Braiam ?

user320

aren't root and boot the same thing?

Braiam

@fossfreedom from here onwards

user320

Braiam not sure how to set up the settings, like i said

Braiam

12:41

if you are not sure, then don't do it... just install it using the big bearded wizard and you will be good.

user320

can anyone tell me how many partitions i need, in my case

the wizard ony gives me the option to install on the hdd

Braiam

unplug the hdd and you will see the ssd

fossfreedom

@user320 to get the best performance/size compromise - root should be on the ssd. /home should be on the hdd. /swap like I said could be either - personally I would put /swap on the hdd - reduces the read-write cycles.

user320

okay. are boot and root the same thing or are the y different partitions

fossfreedom

/boot can be a separate partition if you want it to be. Keep it simple, just have / (root) and boot will be automatically created under it on the SSD.

... but before you start ... you do have a full system image backup of your PC?

user320

12:46

somewhere

yes

home is for files like videos right?

fossfreedom

all user accounts will be in /home - /home/yourname/Music etc etc.

Alaa

Hey, sorry to jump in, but I'm writing a script that first checks the Linux version: "if this version, do this, and if this version, do this".

The "do this" part is pretty big, like 40 lines of code. What's the best way to do this?

Do a huge if statement at the top?

Braiam

@Alaa use a function

fossfreedom

make it a function that you call in the if then else part.

Alaa

Cool. I'll look into functions. I already have the code written though, will it be as easy as just putting "function ()" at the top and that's it?

Or would I have to change some stuff in the code?

Braiam

12:51

@Alaa bash?

Alaa

Yup.

Braiam

@Alaa tldp.org/HOWTO/Bash-Prog-Intro-HOWTO-8.html

function nameoffunction {
    AWESOMENESS HERE
}

Alaa

Awesome. I'll do that. Thanks!

Braiam

if you function require parameters just use $1 $2 $3 $4 etc

Alaa

I actually still have to understand these parameters, "$"-then-something-after-it.

Braiam

12:55

btw, Luis Alvarado took all the close votes from you @Alaa :P

Alaa

I like to call them "automatic variables".

Braiam

lol

Alaa

No, I got them back =P. These votes stack up pretty quickly man.

Braiam

do your function reads some arbitrary data you need to provide?

Alaa

And yeah, you got your 20 before he came in =P.

Can I just declare variables inside the function?

Like, I'll have this inside a function:

SYSCONF=/etc/syslog.conf

And this in the other function:

AUDISP=/etc/audisp/plugins.d/syslog.conf
RSYSCONF=/etc/rsyslog.conf

What you're saying is that I can declare those at the very beginning, then pass them to the function?

Braiam

12:57

dunno... never has done a bash script :P

Alaa

Haha. Well, it's okay. I don't want it to be a "super duper awesome script".

I just want it to get things done.

Thanks. Going back to it.

@Mahesh thanks, I'll definitely look into vim.

it worked as a live CD - but crashes during the installation? Where does it crash?

"it worked fine on my laptop" ... you are installing on this laptop or is this another PC you are installing on?

i am starting to get frustrated with this

user320

17:32

why is ubuntu 13.04 so borken

i see so many threads for 13.04 not installing easy

Rinzwind

17:54

@user320 don't blame Ubuntu. Blame Microsoft with their UEFI.

75%-ish of the problems stem from that :-P

Takkat

Only users who have an issue post here. My 13.04 installed in less than 15 minutes. No issues. All runs out of the box.

So what should I post then?

Rinzwind

@Takkat same! 15 minutes is all it takes for an install. And in the mean time I use firefox to browse the web :D

Takkat

lol yeah \o/

Major mistake you could make is trying to tweak the system, or install it to weird locations or convince a hostile operating system to play nice.

Rinzwind

I do not even think I had any problems installing except for the 1st Ubuntu release :P

and 1 release had a buggy network manager so I used wicd till that got fixed

Takkat

My issue came with 9.04 dual boot when something partly overwrote the Windows XP boot with a Vista boot. This was almost unfixable as Windows kept complaining.

Rinzwind

18:06

That is -all- I can remember that I had problems with. Even the beta's have been kind to me :D (and the NM thingy was from a beta too so does not really count)

Yeah well that is just it: do not dual boot >:-D

Takkat

Dont, yeah.

Mahesh

mine crashes if I use u+1, hence I made it a point to keep the current stable around for emergencies.

and for any important works. :P

Rinzwind

I use Ubuntu on my notebook and game on my PS3. Only for Guild Wars I have a system that has windows on it

Takkat

I have an emergency Windows on the old box in case something needs a new firmware.

Rinzwind

And that windows is XP :D

@Takkat I normally do that from linux with a usb stick

Braiam

Our favourite narutard is here *hugs @Rinzwind*

Rinzwind

@Braiam I am not a narutard >:) I am death noter :D

If the firmware needs a proprietary Windows soft I conside the hardware as crap.

Rinzwind

so be careful with what you say or else...
