The "love" easter egg...

Digi

yah i saw it in the code list and wanted to try it out

Terrance

Great, now I have that song stuck in my head. :P

A.B.

17:27

@ByteCommander Not this question? askubuntu.com/q/677072/367165

@ByteCommander all this commands are available via dbus

Is that understandable terms?

0

A: Is there a way to make sure my system will boot before I reboot? I just ran bleachbit

You can not check whether a restart will be successful. If that would work, then you could also prevent a restart to avoid that a system can not be restarted. ;)

Nathan Osman

Anyone else see the similarity between Opera's new logo and MyWOT's "danger" icon?

Byte Commander

@A.B. No, I passed that one on to Jacob "The Script" Vlijm. ;)

Nathan Osman

It was the first thing to come to my mind.

Byte Commander

I never used Opera, so no, not really. It reminds me more of a Google-"o".

@A.B. How would I use dbus for that, do you know? (or link)

Nathan Osman

I have almost never used Opera either.

Terrance

17:41

I use Opera in Windows when I am working remotely, but no local.

Nathan Osman

I was quite disappointed when they switched from Presto to Blink for their rendering engine.

Presto was way ahead of its time IMHO.

Byte Commander

@A.B. +1 for "Normally, however, each system can be repaired. This is Linux and not Windows."

However, the Grammar N@z! in me thinks you would have to use "every" instead of "each"... Not sure though.

A.B.

@ByteCommander I'm also not sure. :\ @Fabby yyyy

Byte Commander

He isn't a native either...

A.B.

@Terrance is a native

=)

Nathan Osman

17:51

I am as well.

"every" would probably fit better there.

A.B.

@Terrance @NathanOsman is this understandable? askubuntu.com/a/677164/367165

@NathanOsman sorry =)

Nathan Osman

Yes, it's understandable.

Though "to avoid that a system can not be restarted" would probably be written "to prevent a system from being restarted".

But what you wrote is still easy to understand. You're doing fine.

A.B.

@ByteCommander Not without me to make before wise. =)

Seth

@NathanOsman wait, Opera got a new logo?

Nathan Osman

Indeed.

Seth

17:57

It does look the the WOT danger symbol xD

Byte Commander

@A.B. Then better let it be. It's not that important. I'll look it up myself when I have time and feel like answering a few questions.

user136984

18:34

Does anybody know by the way when Shumway will be signed by Mozilla?

Byte Commander

Or the Ubuntu Unity add-ons (xul-ext-ubufox)

Fabby

@A.B. I would say "every"

A.B.

@NathanOsman Thank you =)

He @Fabby =)

Fabby

@A.B. Reviewing...

(and then going to sleep: knackered!)

A.B.

@Fabby =)

I had only two accepted answers today. :\

user136984

Will Linux Mint ever become an official Ubuntu derivative?

RPi Awesomeness

Nope

user136984

Why?

RPi Awesomeness

It's based off Ubuntu, but it's not Ubuntu.

Like Ubuntu is based off Debian, but it's not an official Debian thingy

user136984

Ah...

user136984

18:50

Then VTC this Minty question as off-topic! >:)

Alexander Solonik

Hey Guys

@NathanOsman you online ? :P

RPi Awesomeness

@ParanoidPanda Really, the only reason that official *-buntu releases exist is because it's essentially the exact same OS, just with the desktop environment changed out and Ubuntu is okay with the changes that specific version makes.

Nathan Osman

@AlexanderSolonik Yup.

What can I do for you?

user136984

By the way, when the DE became by default Unity and not GNOME any more at which version was GNOME? 3 or 2?

Nathan Osman

@ParanoidPanda It was Gnome 2.

user136984

18:58

Why did they move away from it? Was it just the design or was there a specific reason why Unity was better?

Nathan Osman

Unity became the default in Ubuntu 11.04.

Alexander Solonik

Hey :)

have a look at this Dockerfile

Nathan Osman

@ParanoidPanda pcworld.com/article/208708/article.html

Alexander Solonik

chopapp.com/#hfzbga9c

now 1st ubuntu will be installed right ?

Fabby

@NathanOsman Reading that too!

@RPiAwesomeness Starred!

Nathan Osman

19:00

@AlexanderSolonik Your container will be based on the Ubuntu 14.04 image.

Oh - you're talking about line 8.

@AlexanderSolonik line 8 can be removed - you don't need to invoke a shell in the container.

Alexander Solonik

yess

Nathan Osman

And even if you did, that's not the correct syntax.

Alexander Solonik

ohh ok

it should run fine without that command

would the command on line 10 execute , without a bash shell ?

Nathan Osman

Yes.

Note however, that you don't have a CMD or ENTRYPOINT directive anywhere.

You may want to include one if you want to specify the default command to run when the container is launched.

Alexander Solonik

Thanks for the advice

btw , how to install 'postgressql' inside the dockerfile , i mean whats the correct command ?

the line at 10 throws an error

E: Unable to locate package postgresql-9.3-pgrouting
E: Couldn't find any package by regex 'postgresql-9.3-pgrouting'

Nathan Osman

19:07

apt-get install postgresql

Alexander Solonik

seems to work

now my Dockerfile looks like below

A.B.

@AlexanderSolonik Vivid or Trusty?

Alexander Solonik

@A.B. huh ? whats that .

Fabby

@AlexanderSolonik What's your Ubuntu version?

Alexander Solonik

sorry new to the nead world :)

chopapp.com/#fd71jw11

Fabby

19:10

(is what A.B. is asking you)

Alexander Solonik

14.04

Fabby

Trusty.

14.04 = Trusty Tahr...

A.B.

@AlexanderSolonik There are no packages *pgrouting in Trusty

But, Why? o_O

Fabby

@A.B. OOV (C tox)

Alexander Solonik

help.ubuntu.com/community/PostgreSQL

sudo apt-get install postgresql-client ?

correct command

?

A.B.

19:12

@AlexanderSolonik Yes

It's a valid package name =)

Alexander Solonik

Do you want to continue? [Y/n] Abort.
The command '/bin/sh -c apt-get install postgresql-client' returned a non-zero code: 1

i get the above error :(

@A.B. TY .

A.B.

@AlexanderSolonik The full message please =)

Alexander Solonik

After this operation, 12.3 MB of additional disk space will be used.
Do you want to continue? [Y/n] Abort.
The command '/bin/sh -c apt-get install postgresql-client' returned a non-zero code: 1

Byte Commander

Did you hit "n" or something to cancel the installation?

Alexander Solonik

noo :(

Byte Commander

19:20

You can add the -y parameter after apt-get to say yes to all questions. But use with care.

@Fabby Btw did you know http.cat?

Nathan Osman

^--- as @ByteCommander stated, use the -y flag to accept the installation without having the command hang waiting for STDIN.

You can also add -q for less verbose output.

Byte Commander

@NathanOsman Btw what do you think of adding a "Http-Status-Code to Cat-image" translation command for George using http.cat?

Like "@GeorgetheDev What is 404?" will post:

Nathan Osman

Possibly.

Byte Commander

It's just https://http.cat/404.jpg, replacing 404 with any 3 digit number. If it does not exist, it will return the 404 image.

Nathan Osman

I was hoping they'd have this one: http.cat/418

Byte Commander

19:29

WUT?

When the heck is that one used? xD

Oh, that's a cute one: http.cat/425

Nathan Osman

@ByteCommander Why... for the Hyper Text Coffee Pot Control Protocol, of course.

Seth

http.cat/301 hahaha

Byte Commander

Aaaahh, I see! ;)

Seth

this site is epic.

Fabby

@ByteCommander No I didn't...

Is there a dog version?

;-)

Nathan Osman

We have our own 404 page.

Byte Commander

@Fabby Did not find one yet. But would be cool!

@NathanOsman From how many images do you pick one?

@blade19899 Different repository structure again?

blade19899

@ByteCommander askubuntu.com/posts/423717/revisions

Nathan Osman

@ByteCommander No idea - we use a third party to serve them up.

Byte Commander

19:37

Ah.

@blade19899 I would add to your question that there's still the normal qtox as well for non-unity DEs, right?

@MuditKapil Did you go bananas again? o.O

blade19899

@ByteCommander Yeah definitely

Byte Commander

And maybe that both packages can't live next to each other.

Anyway guys, it's time for me to go...

See ya all!

Fabby

@ByteCommander Good night!

RPi Awesomeness

@MuditKapil o_O

Nathan Osman

@RPiAwesomeness I had an interesting experience on Twitter last night.

I've never had people make fun of my face before or ask for body parts.

Fabby

19:52

@NathanOsman :D

Mudit Kapil

@NathanOsman pls remove my comments as they are classified

Fabby

@NathanOsman My opinion is: both the father and the mother must agree unless it jeopardises the mother's life: then no agreement is needed.

Nathan Osman

@MuditKapil I've removed one of them.

Fabby

And I would have answered: "I don't need a uterus to have an opinion, just a brain" >:-)

Nathan Osman

Let me know if there are others.

Seth

19:55

@Fabby That wouldn't get you anywhere..

Mudit Kapil

no thanks

Nathan Osman

@Fabby I considered replying with something like that but I can't stoop to their level.

Fabby

@Seth It would get me into a flame war!

:D

Nathan Osman

Unlike them apparently, I am capable of civil discourse.

Fabby

It's a funny read...

Nathan Osman

19:56

<sarcasm>
They are so open-minded and tolerant like they claim.
</sarcasm>

Fabby

Nathan Osman

Google has developed another compression algorithm.

I'll be comparing it to LZMA and bzip2 shortly.

Fabby

Brotli?

Ah... LZH: I programmed that 20 years ago...

You do a Huffman first and then Lempel-Ziff it...

@MuditKapil Change user name...

Mudit Kapil

i changed that but is not working

Fabby

@MuditKapil Have you logged out and in again?

(also: allow 24h for the change to be replicated across all accounts)

I can see intex already...

Mudit Kapil

20:06

yes

but still same user name

Fabby

Have you logged out and back in yet?

Mudit Kapil

yes

Fabby

I didn't see you leave the room...

@MuditKapil log out, close browser, open browser, log back in

@NathanOsman Interesting read though...

Mudit Kapil

no

no change

Seth

Q: ftp user for root directories?

I am setting up my ubuntu 14.04 server. I want to have an FTP (I use vsftpd) access, mainly for my apache2 server, so I added a new user to user www-data group. I also set up the settings for the vsftpd.conf, that I only allow local users, and chroot_local_user=YES. I changed the home director...

Nathan Osman

LZMA still gets better compression. The archive contained images, source code, a Python script, and a WAV file.

And Brotli's compressor is quite slow.

Seth

did you not test tar.gz?

Brandin

I used to be fascinated by different compression algorithms and programs and how well they compress. But now I just always use tar with gzip for everything. It's good enough.

Nathan Osman

20:22

@Seth No, but I've never seen gzip beat LZMA or bzip2. Still, I'll try it for fun.

1,352,785 bytes

Brandin

What about compression speed and memory usage. bzip2 is terribly slow compared to gzip last time I checked.

Nathan Osman

No idea. I was only testing filesize.

Fabby

@NathanOsman But the decompressor should be very fast...

Nathan Osman

Hmm... maybe I should write a benchmark and an article about this.

Terrance

@A.B. Sorry I missed your earlier question. Yes, it is understandable. I was the second +1 for you on that one. =)

A.B.

Actually...I probably don't

Nathan Osman

I'd rather not see where it comes from...

Alexander Solonik

Hey guys

I was running a dockerfile

and i get an error

chopapp.com/#9sjuln4h

.

now one of my colleagues give me the following advice

Fabby

20:47

@AlexanderSolonik You need to change your host OS to Ubuntu if you're serious about running docker seriously...

;-)

Nathan Osman

You need the -y flag.

Alexander Solonik

@NathanOsman yes that was the error ;)

but

Fabby

Ubuntu is the default OS for Docker and you cannot expect us to provide 24/7 support for every minor problem you run into...

(my 0.02$)

Nathan Osman

@Fabby The default OS? The Docker daemon only runs on Linux, yes - but it will run on other Linux distributions.

Alexander Solonik

@Fabby sure ! I'll ask a question , you can choose to answer or not :)

my colleague told me "The non-zero code means that there was an error running this task. To test exactly what's wrong, you can run and login the container, and run this command manually inside the container."

Hi guys, can I ask your opinion on the closure of this one? askubuntu.com/questions/676046/… I hate to see it closed, and I think it differs significally, as it is now.

@NathanOsman :D :D :D

I could have told you that 20 years ago! (though the memory footprint of my compression algorithm using a combination of LZ and H,

had a code segment of 64K

(not sure about data segment any more: I threw away the source about 10 years ago)

Actually, it must have been 25 years ago!!! (I'm getting old)
