@hexafraction Did you get my message in the MSO Tavern

A: Upcoming site design changes

2:14 AM

Oops. Forgot the question mark.

@Lucio After Discourse stopped working because of an old chromium. People got things moving after that. They were also waiting for some team to catch up.. I forget which one.

@hexafraction There was a bug report on that...

1

Way too big for buttons...

2:43 AM

Yay, time to put saucy on the other laptop!

2:59 AM

@jrg Any blazing new features yet?

idk, the iso seems to be corrupt

Uh oh.

Lemme restart into Ubuntu and see for myself.

K

It's working so far..

3:18 AM

@jrg Hm. Mine froze shutting down..

3:46 AM

hi, i just gave four year old an old laptop. it is runnign 12.04

any way to provision users to quickly block them from destroying their innocence?

if you google "i just gave a your old a laptop" you find nothing but people with old laptops. :)

sorry typo "I just gave my four year old a laptop"

Q: How do I restrict my kids' computing time?

I don't understand..

Are you looking for this?

24

Access to our computer (not only to the internet) needs to be restricted for the accounts of my kids (7, 8) until they are old enough to manage this by themselves. Until then we need to be able to define the following: the hours of the day when computing is o.k. (e.g. 5 - 9 pm) the days of the ...

nope

that is the other thing you find

i mean, parental controls

i have screen time desinated

this was super cool by the way.

This?

during screen time, the four year old taught the two year old linux

Q: Parental controls with different settings for different users

16

Does anyone know of a good way to set up some sort of parental controls so that one user account is subject to them, but not another? A couple of friends of mine use Ubuntu and have kids (7 to 10 years old) who use the family computer. They'd like to have some blocking of adult sites. They're no...

3:52 AM

they aren't doing bash yet, since they can't read

but they dig pictures of animals

What are you trying to do?

make it easy to use.

and safe

and hopefully get them into linux early. :)

that is certainly part of the question

Q: Is it true that Canonical shares some user's information with Amazon without asking for permission to Ubuntu's user?

Hasn't this been gone over before anyone?

0

I heard Richard Stallman saying it... He says Ubuntu violates the privacy of the user by giving information to Amazon without permission.

canonical privacy amazon

@WillKop I'm not sure I understand the question...

user interface changes for people who can't read

i have a bunch of old laptops, this happened by accident, i peeled off the eff stickers and gave it to my daughter

Ah..

3:56 AM

it was awesome!

screen time is already limited

internet can be filtered

this kids can't read

they can navigate an ipad. but that is too portable and they get hooked

and expensive if dropped

lol

There isn't any real way to alter the GUI, except by using a separate DE.

Unity is sorta simple..

but kid friendly?

We have this question:

i was looking at edubuntu

Q: What desktop environment is best suited for small children?

12

I've donated my old laptop to my 3 year old kid. Are there any desktop environments designed especially for this age group?

3:59 AM

but i wanted to just add another account, not rebuild the box

i have some stuff on there i need to backup first and can't really be bothered

Well sorry. That's all we have ATM.

no worries!

:)

thought i would check.

Okay :)

A: Which GNU/Linux distribution for a 12-year old system?

Here is another similar question:

11

Puppy Linux: Wary is great for older hardware.

4:05 AM

thanks seth, i am just going to make some links to pbs kids and stand there watching if things hang to help before it is frustrating

Okie dokie.

This could be a cool little project.

to add to the enormous list you must have of cool projects.

i'm happy to share my resuts

results

for free. lol.

Of course :)

Xfce is amazingly customizable. As well as KDE, though I'm not sure it would run on an older machine. Just my 2 cents.

Anyway, I'm off!

take care

thanks

4:33 AM

How do I get "make" without Internet on a new Ubuntu Server installation?

9:45 AM

anyone here?

@Jonas download the debs and transfer on server and install?

11:15 AM

@Mahesh what debs do I need?

I guess there are other build tools I would need for compiling drivers after a new installation

erm, make and its dependencies that you don't have.

try this hack.

I probably need gcc and such tools to

you need the entire development toolchain?

I think so

I have a dirty idea.

11:18 AM

@Jonas That didn't work for you?

do you have another ubuntu machine?

need to compile a driver..

@Mitch the driver you linked to need to be compiled, it´s just source code

no, no other ubuntu machine

I did it without Internet access per the readme.txt included in the archive.

he needs the dev toolchain.

gnu make, gcc, and stuff.

was this server ever apt-get updated?

A: No network interfaces detected when installing Ubuntu Server on Mac Mini

@Mahesh Can you please take a look at the answer, and the link?

0

I have been trying to install Ubuntu on my Mac Mini, and been having all sorts of problems, one of which is Network. So here is what I did. I updated the firmware Then I installed Ubuntu without network, and when the installation was done, I downloaded and installed the driver, and it all work...

11:22 AM

oh. crap.

okay. try this.

apt-get install synaptic --print-uris

does that give any links?

or does it say you need to run update?

I presume yours is 12.04?

I have a 12.04 machine in the cloud that can prolly help.

@Mitch I only find instructions for installing from RPM package or building from source in that archive....? so I´m going "build from source"-way and need make and other build tools?

@Mitch are you on raring?

here is a workaround.

@Jonas inside the archived file there is a file called tg3-3.129d.tar.gz file. Inside that you will find the readme on how to get it. Look at what I've added in my answer.

If you have the debs for the stuff you need, the problem is solved.

@Mahesh yes on raring

11:27 AM

@Mitch you have the toolchain installed?

@Mahesh No, fresh install

brb

great!

do a apt-get install make --print-uris and give the output to jonas.

he can download those debs from any machine he has access to.

copy them over somehow onto the mac,

and run dpkg -i *.deb in that folder.

he will get the toolchain installed, and can happily compile the drivers.

but mitch's answer says that make is already present in that tar file.

@Jonas

@Mitch I look at the same folder, but there is no Make or GCC binaries in the archive... only C source files and a Makefile

@Mahesh no, I can´t find Make or the build toolchain in the tar file, only source files

okay. wait for mitch to return. he will either show you where the make and gcc are, or he can provide you the urls of the debs youneed to install.

either way, you will have whatever you need to compile that driver.

but a apt-get install make --print-uris would not be enough, since it doesn´t include gcc, and who knows if I need other tools?

is the build chain tools included in the installation media?

11:39 AM

@Jonas I know that, but jut do as I added in the answer, and try :)

I'm going to add an image of what was done.

@Mitch when I typ make I only get a message "The progam ´make´ is currently not installed. You can install it by typing: sudo apt-get install make"

because I don´t have the build tool chain installed...

can I get it from the installation media in any way?

@Jonas I swear to god, I didn't install anything. Ran the server setup from ISO, and then downloaded the file, and ran it, and it worked :)

@Mitch good for you, but it doesn´t work for me :(

@Jonas Let me see if I can find a different file.

is the build tools an option when you install Ubuntu Server?

11:48 AM

@Seth fantastic.

@Jonas as i recall, no.

ok, :(

Q: Rsnapshot destination full - how to safely rerun?

I´m trying with a new fresh install and try to install build tools during installation

@Jonas If you wanted to the package name is build-essential to pull in all the useful bits (even if it's not on the menu, I would hope it's on the disk so a quick respin gets it in there)

$hexafraction$

@Seth You've already told me a bout that proposal :-)

And yes, I'm back from a very long break, just to take another in a few days.

Refer to my starred post complaining about chlorinated water/

@CallmeV do you know in what section "build-essential" is, when selecting manual packages?

$hexafraction$

@Jonas devel

12:21 PM

^that.

@Jonas I will upload a .deb file for you to try in a minute, and I'll give you the link

$hexafraction$

@Mitch It's a giant metapackage.

You'd be better off grabbing as many dependencies as you find necessary, and work from the leaves of the dependency tree, not the root.

@hexafraction found it, thanks! but how do I "add" it? if I press enter I get five RED "depends": dpkg, g++, gcc, libc6-dec and make

they don't have g++ on the server install media? that's odd...

its the .rpm file included in the drive archive converted to .deb. will that work?\

12:26 PM

@CallmeV I can find g++ in the same directory... but how do I add the packages that I want to install?

last time i chose things to install it was space bar to toggle the selected package and it resolved the dependencies for me

@Jonas Give This a try.

@CallmeV I can´t see the beginning of each line, it seems, so I can´t see what I have selected :(

@Jonas I need to leave for a while, but I'll be back in a couple of hours. Let me know. Thanks :)

ok

1:29 PM

@CallmeV I think + was the right key to hit, for selecting a package... I´ll give it a try now!

java scripts

Is that JavaScript or a Java script? @_@

$hexafraction$

I don't know. I just answered in terms of both.

> its a normal java script like if i enter user name and pswd in my login.php page on click of submit button the java script has to perform the an validation script to correct user was logged or no but this script is not getting called only and is there any thing that i need to install for java script to work in my linux system ? because the same script works in my windows system , this is happening to all my java scripts where ever i call not specific to this login page

@hexafraction that was an answer from her on the same question

$hexafraction$

Ah. (by the way, this is obsessivefoss with a username change. I'm back)

@hexafraction I can tell :)

$hexafraction$

Yes ,the gravatar and the fact that my dynamic IP is more or less static.

4:32 PM

I can see your previous username.

$hexafraction$

Ah.

now tell me if it is javascript or just java?

$hexafraction$

Then again, I'm going to be away again this week for a few days, and not in a 3G-enabled area.

@jokerdino I answered both, I'm assuming the former

okay. will edit the post after dinner. brb

Good Night

6:25 PM

hey? any Php Programmers in here? :)

I'm in need of some help

I used to be one.

What's up?

@NathanOsman I need to generate random usernames and passwords for users

The usernames are generated from their names and passwords from numbers

So basically you want to take their real name and generate a username using a certain set of "allowed" characters from the name?

@mojo706 php.net/manual/en/function.uniqid.php ?

is that not easier? :-P

or this is easlily alterd:

function random_password($len = 7, $mixed_case = false)
{
$a = "abcdefghjkmnpqrstuvwxyzABCDEFGHJKMNPQRSTUVWXYZ23456789";
if(!$mixed_case) $a = strtolower($a)
$out = "";
for($i = 0; $i < $len; $i++)
$out .= $a[rand(0, strlen($a))];
return $out;
}

(creates a random password; change the $a to the user name and volia >:) )

6:43 PM

@NathanOsman yes

@Rinzwind thanks

@NathanOsman I hadn't even thought of that

I would suggest not to mangle the name. It is too obvious and if the name is short....

plus it probably annoys the users since they need to remember a login they them self did not get to choose.

@mojo706 That would be easy to implement using a regular expression.

@Rinzwind It wasn't my suggestion its part of a project

for the user name you should use NAME+ID

like : artuer1324

@mojo706 aha :)

6:51 PM

@NathanOsman how

@Lucio I agree. Or at least suggest it.

@Lucio great suggestion
Now I am going to code the script I'll put it on Paste bin for you to see

you will get "feedback" if you mess up >:D
LOL

@mojo706: This is a good place to start.

Use that to eliminate the characters you don't want.

@Rinzwind Your answer is great, but that is a duplicated question :)

7:02 PM

@Lucio grrr >:)

anyway I upvoted it

I mention this because the post should be merged

deleted it >:)

@Rinzwind NO!

fine

undeleted it :-P

Your answer is absolutely valid, if the question is merged, your answer should be moved to the duplicated

7:03 PM

tsk >:)

tsk ??

I don't speack Russian yet..

@Lucio since when is tsk russian? >:D tsk :=)

jk

But I don't know what does it mean :P

lol

en.wikipedia.org/wiki/Tsk ;-)

even wikipedia knows it >:D

@Rinzwind Him knows everything

Oh, TSL= The Turkish Armed Forces, (Turkish: Türk Silahlı Kuvvetleri)

7:12 PM

@NathanOsman very complicated

@mojo706 you can not say that PHP is complicated dude

@Lucio the method @NathanOsman suggested is complicated and yes sometimes PHP can be daunting

Don't worry, I'm just saying :)

@mojo706 naaa... I rarely use PHP myself but I found it rather easy to use. At work we mainly use JS and perl :D Perl is annoying ;-)

Not really. Let's suppose you want to only allow usernames with letters:

$pwd = "Bob Smith";
$pwd = preg_replace('/[!A-Za-z]/', '', $pwd);

It's pretty simple once you get the hang of it.

7:18 PM

@NathanOsman now with that example its easier. Plus I was reading through the whole page and I only just understood the example :).

@Rinzwind I've never tried Perl probably never will now

Okay, is a mod around?

@jrg ?

hi

Personally, I would tend to steer people away from PHP.

It's a very poorly organized language and makes it really easy to create serious security errors.

7:21 PM

I'm really lost...

But I prefer it @NathanOsman

@NathanOsman hmm so true :-)

easier to understand and best if well understood

is gksu installed on newer systems?

@mojo706 the problem is those parts you think you know but don't ;)

@jrg pkexec

7:22 PM

so i'm confused.

@Rinzwind true

@mojo706 Why?

@jrg pkexec is the new gksudo ;)

@jrg no.

@Seth then we shouldn't use gksudo

just pkexec.

7:23 PM

Once you understand how Python works you will look at PHP and feel sick to your stomach at how awful it was.

@jrg yes. I believe there is a topic on meta about this (???)

Yes, there is, but that question is messed up.

@NathanOsman I am actually studying both. Advice from the lecturer

@NathanOsman can you tell that to my boss please? :D

@jrg Could you just migrate it to main?

I don't think he meant to post that specific question on meta..

7:25 PM

@Seth migrate to main and reopen?

Q: PSA: gksu is no longer installed by default

Yes.

Also, meta discussion:

Turns out gksu is no longer installed by default. Some things still depend on it so it might be installed on your system - but on a clean install, it seems it's no longer required. As for why, see: Why is gksu no longer installed by default in 13.04? Historically we have used gksu a lot here but...
