what is this?

@Seth Some of the packages necessary to use the Ubuntu SDK

I'm going to attempt to create a Scope for the Scopes contest...

Dunno if that's gonna happen...

oh I see.

It's crazy

Oh wonderful. And I can't stop it...

12:55 AM

It is absurdly hard not to just build my desktop...

must. wait. for. ESD. BRACELET!

I just leave it plugged in and ground myself to the case chassis and make sure part of a forearm is touching the chassis. but don't do it if you don't trust it. i won't be held responsible for some astronomically improbable event.

@hbdgaf Yeah...but it's ~$5 and I'd rather be safe than sorry

If I fried my CPU/GPU...I would rage SO hard

That's fair. I've always done it that way and never fried anything, but as you say. It would be upsetting.

Yeah

That moment when you try to save a file in a text editor by pressing Ctrl+O

That moment when you press esc only to realize you remapped it to caps lock

1:05 AM

lol

I am actually really liking coding in C++

It's quite...mature feeling

And it's really not all that complicated.

Granted, it is more complicated than Python, but it's nowhere near as bad as ASM

wait until you try writing a Win32 app in it.

hehe...no thanks

Of course that's Win32's fault and not C++ but..

#Win32Fail

So I just wrote this line of code and it feels icky:

    if os.path.isdir(os.path.join(os.getenv("HOME"), "Desktop")):

1:08 AM

@Seth Oh yuck

split up your import from import os to from os import path, getenv. then it would read:
if path.isdir(path.join(getenv("HOME"), Desktop)):

I forgot a closing parenthesis and couldn't resist adding a comment "lisp alert" above that line xD

@hbdgaf ooh that's an idea. I might need other bits of os though. If I don't in the end I will definitely do that though.

@Seth it reads more nicely that way for sure.

indeed.

In other news, every time someone says we're too hard on bug questions here, I'm tempted to refer them to the KDE/Kwin/Wayland bug policy which reads as follows: I found a bug, what should I do?
Open your text editor, fix it and open a review request on Review Board.

No joke, that's actually on their website.

1:47 AM

THE RAGE IS REAL

ARGH. I get maybe halfway and the dang computer disconnects..ruining the 240MB+ download. I hate my internet SO FREAKING BAD

Just be glad you're not old enough to have experienced sub-56k limited hour usage dial-up plans. Kids these days...

The driver/launcher for my first modem was so flaky, I had to manually type:
atz
atdt 5551212
and the call waiting beep made my connection drop.

@hbdgaf heehee...well, but you weren't trying to stream video

Is it bad if my chroot gets broken?

Depends on what you mean. Something escapes it, yes bad. You can't get it to launch because you didn't link something in there properly - not nearly as bad.

@hbdgaf Because the stupid Ubuntu SDK download failed and started again, but I want to stop it, and it's giving me this when I try to close it...

That's not horrifying, but it's still going to make you upset.

1:57 AM

Wonderful.

What would it do?

The window is just stuck like this:

Exactly what it says... The scopes dev stuff builds a non-native arch chroot to build scopes for your phone - for example. You're talking about breaking that and having to wipe it out and set it up again.

@hbdgaf So...I would have to reinstall?

'cause it never actually got anywhere...

The packages. Yes.

@Seth No, of course not! We do some pretty aggressive edits on top/accepted answers to make them right if they're wrong though. But no, not copying. I had not realized that was what I was endorsing.

@hbdgaf So, I could just force-kill the app and run sudo apt-get purge PACKAGES and be fine?

2:00 AM

If I'm reading your situation right, yes.

kk

'cause it's totally stuck

eh...I'll let it do its thing...

I'm going to go to bed soon anyways

I wonder if anyone would have any interest in an appliance that dispenses apt-mirror archive ISOs at local coffee-shops. rimshot

That would be pretty sweet :)

Like, you just plug your PC in and it downloads apps?

You bring in your usb hd or pay for a pantload of DVDs. You get a current apt-mirror of the accepted repos and several ppas.

Ah

2:04 AM

Your next question would be "I just used this theoretical appliance, but now my HD is full"

That would definitely be useful :D

But the bandwidth required to keep it up to date...

Would be after closing and before opening said coffee shop. So, no increased cost to the coffee shop itself.

Phew. So I've got this exercise in the book I'm using to learn C++, and I have to have a computer play guess my number with a human. As in the computer has to guess the number.

This is freakin' AI programming right here!

It could be infinitely complicated.

Does it give back high-low?

I'd have to program that.

Or, I could just code:

2:11 AM

If it gives back high low, statistically the computer wins. You pick the middle number. If you're wrong you divide the distance to you last maximum high/low by two and guess that over and over again.

int main()
{
    CPUguess = toGuess;
    if(CPUguess == toGuess)
    {
        cout << "CPU Wins!" << endl;
    }

    return 0;
}

THERE WE GO

No, you use: if computer.first_turn: print(computer_wins) more or less.

True

Morning!

$ sudo hdparm -Tt /dev/sda

/dev/sda:
 Timing cached reads:   22542 MB in  2.00 seconds = 11281.40 MB/sec
 Timing buffered disk reads: 376 MB in  3.02 seconds = 124.64 MB/sec

What's the meaning of cached reads?

11GB/sec? Is that possible?

8:04 AM

cached means its partially stored in memory of some sort

Timing buffered disk reads means non-cached?

What change should I expect after switching on a SSD?

On my Ubuntu laptop, I have Windows inside VirtualBox. Problem: Windows has Internet access ONLY if Ubuntu is connected to my office's WiFi. Windows does not get Internet at home or when using any other WiFi network. Any idea? Should I ask as a new question?

Hi
How can I remove duplicate lines if first column with : delimiter is the same?
for example I want to delete second or more duplicate of A and add its value to previous line.
input:
A:5
A:1

8:50 AM

GitHub Rocks!

there pages generator also: EuroCMS by blade1989

Yaay

@blade19899 Actually, my contributions calendar app is more or less a hack. :D

It generates commits in the past.

I'm also working on something related: bloggify.org

Not based on GitHub pages, but it offers GitHub integration.

@IonicăBizău Nice! Yours looks more polished. My EuroCMS isn't even ready enough to be called an alpha!

My website runs Bloggify: ionicabizau.net

I run wordpress ;p

Uncool, but it mostly works

I love Wordpress and I still use it for creating websites for people, but for a blog like mine, it's too much. :-)

8:57 AM

@JourneymanGeek EuroCMS: Your free, easy to use, and customizable Content Management System. Soon a Wordpress alternative!

@blade19899: "soon" :p

@JourneymanGeek Probably a good month... or two, three, four, five.... six years...

6-8 weeks, SE style? ;p

Lots of distractions. Plus I'm the poster child of procrastination.

Of my Current roadmap, I'm at step 5. EuroEditor. An Editor that rich editing support and markdown. Trying to write every feature that LibreOffice writer has. I even used the icons for it.

pbuilder is failed.

how to do it?

@xiaodongjie Did u try: PbuilderHowto - Ubuntu Wiki?

sure, sir

I read it.

I tried to build virtualbox_4.2.10 in ubuntu12.04 with pbuilder

and virtualbox_4.1.12 that is ubuntu12.04 lts statnadrd version, too.

but pbuilder is failed with dependencies

I have a firewall file saved in /etc/firewall.conf. Everything is ok, I can use it for "iptables-restore /etc/firewall.conf" with success.

10:27 AM

Hi everyone. I am seeking for a bit of advice.

My advice? RUN RUN AWAAAAAYYY!

(more seriously, don't ever ask to ask. At worst, someone will point you elsewhere)

Days ago I posted a question at SuperUser regarding an issue I have with FreeCiv, I am unable to resume the games I started in Ubuntu on a Android system.

The folks there closed the thread almost immediately. I kept asking the reasons and they kept providing different reasons.

oh yeah, that one.

(I'm an SU mod)

@LuísdeSousa is that more appropriate for android.stackexchange.com ?

I think the issue we had was on the android side of things

10:30 AM

So the point is: can this issue be scaled up somehow?

@fossfreedom: its a bit of an edge case there too. He wants to export a savedgame from a pc-ish system to android.

Is there anythig like a meta-meta-SE ?

meta.se is probably alright if you want to complain about SU moderation, or not knowing where a question goes

do you have an url for that?

HOWEVER, I'd warn that SO users sometimes are clueless about other sites.

10:32 AM

@JourneymanGeek doubtful its appropriate for superuser - if you word it carefully android stackexchange should accept it. No harm in trying.

In your shoes I'd mention it was closed on SU. Or ask if its on topic on meta-android. Possibly the android chat room

Rinzwind

10:53 AM

@JourneymanGeek as opposed to us on AskUbuntu that just know about them but do not care about? >:-D

@Rinzwind: I prefer that ;p

oops

I'm pretty platform agnostic anyway

I might be switching back to linux soon, have a tech support position I'm interviewing for next week

12:54 PM

@JourneymanGeek Yay! Come back into the fold!

1:08 PM

@terdon oh. I have a secondary Linux system. Scho

School was windows so most of my boxen are windows

1:26 PM

@JourneymanGeek I know you do, and I know you know your way around it. I also know you have been lured away from the path by promises of... umm.. something or other.

1:43 PM

@terdon: games ;p

Also laziness

Yeah, games is a point. Granted :)

Also, word is awesome for proper stupid simple citations

(granted I use the son of the citation machine when I'm too lazy to spin up an instance of windows to run office trial on)

@JourneymanGeek Ah, no, sorry. There we disagree. But then, I've actually taken the time to learn LaTeX.

@terdon: they insist on word docs ;p

@JourneymanGeek Who does?

Your school? A technical school!?

1:48 PM

Don't forget, I also did a major in management.

@terdon: Oddly enough, yeah

@JourneymanGeek Ah, OK. Imposing an inferior, more expensive product over one that's better and free. Yup, sounds like typical management :)

;p

guys, can someone cite some good points on how to persuade a windows user to switch over to ubuntu. I have never been able to do that. their strongest argument being windows is free too (free as in pirated), and topped with a pirated antivirus, they present a very strong case for me to fight against. :P. any help would be great.

2:07 PM

@astrob0t I have faced the same problem. You could try telling them what most pirated software give as a bonus(hardcoded malwares and NSA property maybe). this helped me make others at least think of switching to linux.

@astrob0t you need to be fairly open to use another operating system. If they are saying "windows is free - antivirus is free - my games are free" ... then perhaps they have a rather closed outlook on life - they probably will never 'convert'

@astrob0t: One does not convert a user

One makes a value judgement

(also, refuse to support windows systems ;p)

@RegisteredUser , the fear of NSA won't work out where i live. But @fossfreedom and @JourneymanGeek present fair points.

I switched to linux cause I realised I was mostly using a web browser and some linux tools anyway

I semi switched back to windows cause of gaming, and school stuff

i can say whatever i like to them , maybe slip in a few lies , but unless they really want to change their outlook, all my tries would be futile. maybe i would give up?

2:18 PM

if its a fairly good friend - invite them around - set up a demo and show them some great tricks. Compiz Cube etc etc.

@astrob0t 1) faster, more stable 2) safer 3) no large corporation involved and your data is not being shared with anyone (well, on non-Ubuntu Linux anyway) 4) infinitely configurable 5) prettier

@terdon It maybe a bit misleading to say that no large corp is involved in Linux, when large part of the code comes from Google.

Q: Creating users with groups in Ubuntu Server?

0

Typically when I create a new user in CentOS / Redhat with the command: useradd user The permissions that it is assigned to the user typically works fine. I believe everything is restricted to its home directory. I would like to accomplish a similar thing with Ubuntu Server. I am using the fo...

ubuntu centos permissions users cgroups

6) Cooler if that's relevant 7) if you work with text files, it is much, much easier but that depends on what you do 8) Believe it or not, easier and faster to install

@RegisteredUser WHAT?

Whatever gave you that idea?

You're confusing Linux with Android.

And corporations are involved. Canonical, RedHat, even HP and IBM have contributed a lot of code to the kernel but none of them own it.

I've converted a few people but always by installing it myself and offering them free tech support :)

I should have said Linaro instead of Google.

And google does put in some code.

2:25 PM

ok . ok. just noting them down.

nice points

@RegisteredUser That's fine by me. What I dislike is a corporation that tries to lock the system down and only allow users to do what they think we should (see Microsoft and Apple). Canonical, RedHat and even Novell may have their own distributions but at least they don't try and tell me what I can and cannot do.

More than fine, really. It's great that large, for-profit organizations are contributing to FOSS.

As long as they keep it FOSS.

@terdon That is the exact point. We should tell people that Large corps are involved, but don't own it and don't directly control it.

They contribute. There's a huge difference.

Again, with the exceptions of RHEL, Ubuntu and SuSe.

Which FOSS software are used to provide a cloud agent(which would provide PaaS and SaaS services) on a Ubuntu server?

2:41 PM

@RegisteredUser so so there are a bunch of different things with cloud...

you can do openstack, but that'll require multiple servers.

I used dokku at a prior job.

dokku is a PaaS implementation, like Heroku.

@jrg So if I am to do so on a small network, say a single college lab for example, which will have 1 server and about 20-30 computer.

And are dokku and heroku OSS?

@RegisteredUser So you have 20-30 machines that you can have be part of this cloud?

No, I have nothing.

I;m just speculating :P

Q: Should we add the hackintosh tag as synonym for mac?

dokku is OSS. it's a similar workflow to heroku, which is not open source at all.

@RegisteredUser ah.

Let me sketch my home setup

eh, sketch doesn't work too well.

so i have 4 boxes at home:
- Intel NUC (small server)
- Mac Mini (Similar specs to NUC)
- Homebuilt server
- Raspberry Pi (soon to be again)

The Pi is the control node for all of them.

it runs all the time, and i monitor the rest of the hosts.

the mac mini hosts the timemachine backup for my laptop, so it's mostly irrelevant.

the NUC and the homebuilt server are the fun parts

homebuilt server runs Dokku and postgresql - it's my PaaS

the PaaS runs all sorts of stuff - some of my personal, homegrown apps, as well as some open source ones.

While reviewing I need to remount Hackintosh Disk r/w I was wondering whether we should create a hackintosh as synonym for mac. There are quite a number of questions with "hackintosh" in their title or text. Since I don't have enough points yet to have the privilege of creating a synonym myself I...

discussion

2:50 PM

I punched holes in the firewall for it, so I could ssh into it, and then tunnel individual apps back.

the NUC does a bunch of stuff - backups for the homebuilt server (database dumps every hour).

most of the software is homegrown.

but the backbone is Dokku.

not sure how i would scale that to be 20-30 machines...

Q: Java appletviewer on arm ubuntu

I have a ubuntu on arm cpu, where i would like to run a java applet standalone (i.e. not in the browser) I have the iced tea plugin installed and it works in firefox. But when i type appletviewer applet.jar it immediately exits without any message or window being opened. How can i debug this?

3:27 PM

How can I touch multiple files with multiple extension? I want to create for example 5 files but with this command it creates 25 files.

touch File{001..005}.{01..05}

@terdon @fossfreedom i have been doing this for some of my good friends and my family and they are quite happy (though they were a lot confused at first.) but the problem lies with convincing acquaintances.

@KasiyA Tricky, actually. Might be worth a question.

I can imagine a solution involving arrays but it ain't simple. There must be a clever hack for this.

I can not find about that on my googling ;)

If this is useful for future, can I ask it on ask ubuntu?

You want to create 5 files with 5 different extensions or 5 sets of 5 files with different extensions?

@KasiyA Yes, yes you can.

for example my desired files will be like follow:

file001.001

file002.002

file003.003

file004.004

file005.005

or extension with

alphabetical, like

file001.A
file002.B
file003.C
file004.D
file005.E

3:42 PM

so each file with a different extension?

yes I think ;)

it is just for a fast test/create files for some questions that needs to work on some files with multiple extension

names=( File{001..005} )
ext=( {01..05} )
for((i=0;i<"${#names[@]}";i++)); do touch ${names[$i]}.${ext[$i]}; done

That will work but is not very elegant. I can't think of a simpler way though.

not worked

no files create

@KasiyA Try again, I had a typo. The first line should have had names not name.

uh

worked

but there is no easy way

It's also harder than copy pasted and renamed. and also hard to remember

:)

Thank you

3:47 PM

I know... It's not good. I'm trying to think of a better way but I think it deserves being asked as a question.

Maybe on U&L instead of here though, there are more hardcore command line people there.

Owkey I will ask a question

is this question readable? not sure whether I am not making it too complex:

But my bad english cause to late post ;)

Q: Should one call this an inversed differential backup and how does one achieve it?

0

I make a lot of backups. I do so on different disks, which are stored on different places. I am looking for a type of backup, but I can't find its name (which I need in order to figure out whether rsync or another ubuntu tool can help me with it). Here is what I am trying to achieve. Always k...

backup deja-dup rsync

@KasiyA Don't worry about that. Just do your best and someone will edit it. PIng me if you like and I'll do it.

3:49 PM

Ok

Ah, here's a simpler way:

printf "%s\n" {01..05} > ext
printf "%s\n" File{001..005} > names
touch $(paste -d ". " names ext)

Ha! You can condense that to a one liner:

touch $(paste -d '.' <(printf "%s\n" File{001..005}) <(printf "%s\n" File{001..005}))

That's probably the best you can do though.

Here's a python implementation:

import this

   files = range(1,6)
   extensions = range(1,6)
   for file, extension in zip(files, extensions):
     filename = "file00" + str(file) + "." + str(extension)
     print filename

that has its own problems of course.

You could create the files with:

open(filename, 'a').close()

in place of the print.

@Seth But that's the same as using bash arrays. Just in more lines and an external script :)

I don't get you python people with your long scripts :P

3:55 PM

@terdon yep, but easy to remember ;)

@Seth For you maybe. Not for me.

Don't you need to import anything? I though python always needs something or other imported.

Well to each his own. I didn't really expect Kasiya to use python anyway.

@terdon readability, readability

@terdon Nope.

@don.joey Again, depends on what you're used to.

I must say that the for foo,bar in (array1, array2) is pretty cool.

3:57 PM

@terdon Indeed, for python people Seth's example is readable

Do you need the filename =? Can't you just print without an intermediate variable?

@don.joey Do you really find this hard to read? touch $(paste -d '.' <(printf "%s\n" File{001..005}) <(printf "%s\n" File{001..005}))

you could, but messy..

btw, this site is pretty cool: repl.it/languages

(I'm on a friends Windows PC so didn't have a python interpreter lying around ;P)

What is it with you youngsters and python? Why no Perl? cries

@terdon It would take me a little bit, but I could figure it out.

Fair enough, I must admit that I understood the python thing without actually knowing any python. Or next to none anyway. What's zip?

Rinzwind

4:02 PM

It starts with a W! And it starts NOW!

@Rinzwind Huh?

@terdon zip is the function that does the two array magic.

it iterates through both arrays evenly.

Oh and @don.joey yes, I could understand your question. I have no idea what that would be called but I think it will take a script to do it.

@Seth Ah, OK. Neat.

Q: How to create multiple files with different names and different extensions?

I did

0

I'm trying to create some files that has different names and with different extensions. Let say I want to create for example 3 files with following name and extension: File001.000 File002.001 File003.002 Or with alphabetical extension: File001.A File002.B File003.C Also it would be better i...

command-line files touch

@terdon

@Seth

@KasiyA Would a python script count as an answer or do you want one compact command like bash?

4:11 PM

if it's possible I want in bash and command line not in script

yeah I figured.

@KasiyA random file name sis much simpler. Just use mktemp.

How?

@terdon tbh I find it a bit daunting for a bash noob like me, but I like your three line version

Yeah, joining things up like that takes some practice. I would never have thought of it and probably wouldn't have been capable of it before hanging out on U&L for a while.

4:20 PM

@JourneymanGeek I believe your fav. backup program does something similar to this, no?

I realize it's Windows software but..

@terdon I want random with random extension but when I use mktemp XXX.XXX it creates XXX names with different extensions ;(

Pandya

@KasiyA Yeah, that gets more complicated. Working on it.

Ok

@KasiyA:

for i in {1..5}; do
mktemp $(head -c 100 /dev/urandom | tr -dc 'a-z' | fold -w 5 | head -n 1).XXX
done

It is generally easier to just use mktemp though.

Let it put the files in /tmp/tmp.XXX

4:33 PM

Thank you. I think it's easy to use just random ext into for loop. ;) fine
