Q: Change permissions for files created by docker daemon service

I'm trying to change the default permissions assigned to files when created by the docker daemon by changing the default umask. The docker daemon service runs as root and creates the files with umask of root. I tried changing the umask by adding a command to /etc/init.d/docker and also passed the...

Q: Using Grep Command Without Directory

Can you use the grep command without specifying a directory path afterwards? Example: $ sudo grep "filename" / I have also tried this: sudo find / -type grep -l "filename" Still no luck. Basically I am searching for where the LoadModule is specified in the Apache2 Config file. I thought ...

ubuntu grep apache

@jokerdino hhhmmm I don't :/

In Firefox or Chrome. I even did a hard refresh

Not a person... a theremin. :P

Theremin is a person.

@Rinzwind Radio 538. Nice. Me too

user136984

Because my JS course seems to be somewhat outdated...

@ParanoidPanda WHAT!!!

JS!

user136984

What?

Looks good so far @HenryWHHack keep up the good job

YOUR KIDDING OMG JS what's next C

10:26 AM

Hey ! C is an awesome language !

@Serg Still in dev mode

I do despise javascript but C is awesome

@ParanoidPanda @Serg : Good morning my friends ! :) How are you today ? What about your health ... better ?

@cl-netbox still the same - coughing

a lot

user136984

@HenryWHHack: I'm only learning JS to help fix a bug in gnome-shell...

Can I learn c online

@HenryWHHack yes, like any other language

10:30 AM

oh

@Serg nice to hear ! ... maybe a little bit more a lot better now ? :)

@cl-netbox nah, nothing better. Coughing less frequently, but still painfully. Cannot breath properly

If anyone here is a computer geek or nerd when I say computer you say code!

computer

CODEZ !

:p

I like this better: When I say "drink all the booze", you say hack all the things

@Serg hmmm ... I thought it had worked ... :)

10:37 AM

@cl-netbox heh . . . sure makes it a little better

@cl-netbox Why is your profile photo so EVIL?

How can a I guy on youtube say he can teach you a whole PL fake you can't learn c python or any PL in one video fake!

user136984

How exactly do you 'ping' somebody on IRC?

ugh . . . i cannot stop being pissed . . . . I am not going to microcontrollers class today . . . let those idiots f@ck with the code by themselves, because all the last 2-3 labs my partners didn't do jack-sh!t, while i'm the "coding" guy . . .

11:22 AM

@Takkat I am not a scammer!

@HenryWHHack you should not use these tablets then!

user136984

Now, I would be incredibly pleased if someone could tell me what the isGreeter variable indicates in gnome-shell.

@Takkat In the correct dose, nitroglycerin is actually used as heart medicament.

And I still need to raise 46 more flags to get the Marshal badge, so they could keep spamming for another few days... ;)

@ByteCommander it is but our tablets are made by real men. They have a much higher dose and a much more immediate effect. They are guaranteed to work. Money back if not satisfied.

<rant> why on earth OpenOffice and LibreOffice start with page style as Default Style ? Like duh, every beginng of the document is FIRST PAGE ! wouldn't it make sense to actually make default format a FIRST PAGE FORMAT ? </rant>

@ParanoidPanda You have experience uploading .sh scripts to a ppa?

user136984

@blade19899: I did it a long time ago and have no real memory of it, but you need to turn it into a deb file and then you should be able to upload it.

user136984

What is exactly is meant by the "gdm greeter"?

11:35 AM

@ParanoidPanda you know what greeter is , right ?

thanks! lunch time!

the login screen

Prior to version 9 , Ubuntu was using gdm login screen. Now they use lightdm. gdm is still available though

user136984

@Serg: Ah, right, so the isGreeter variable would probably indicate that we are on the login screen right?

probably

user136984

@Serg: Could you just have a quick read through this bug and tell me if you think that's what the variable is for because I want to be sure...

user136984

11:39 AM

Would the locked screen count as a greeter too?

Making. Bosom. Tissue. Swell.

I don't know, Spam. When you have to run every word through the thesaurus, you have the question the point of posting your rubbish in the first place. Nobody is searching for how to swell their bosoms.

Maybe they plan on editing it later if the thinking is filtering initial posts instead of searching the db?

@ParanoidPanda So basically there's issue with accessibility menu, that's what i understand. But what exactly is the issue ? My brain isn't quite braining right now, can you explain ?

user136984

@Serg: I think it's because people see it and start fiddling around with the settings in it because the "person" icon makes them think it's to personalize their account, when actually it's more likely to increase zoom and give them a big cursor... :D

user136984

@Serg: I'm fixing a different bug, but I need to understand for it what the isGreeter variable exactly indicates.

user136984

11:47 AM

@Serg: I need to also understand why it has different values here:

user136984

    'gdm': {
        hasNotifications: true,
        isGreeter: true,
        isPrimary: true,
        unlockDialog: imports.gdm.loginDialog.LoginDialog,
        components: ['polkitAgent'],
        panel: {
            left: [],
            center: ['dateMenu'],
            right: ['a11yGreeter', 'keyboard', 'aggregateMenu'],
        },
        panelStyle: 'login-screen'
    },

    'lock-screen': {
        isLocked: true,
        isGreeter: undefined,
        unlockDialog: undefined,
        components: ['polkitAgent', 'telepathyClient'],

user136984

Why is it true when we have gdm, and undefined when we have locked-screen?

@ParanoidPanda well, gdm is obviously is greeter so it's set to true, just like i lightdm would be set to true

lock-screen is different

@Serg: Right, this is all in Ubuntu GNOME by the way, in fact that code comes from sessionMode.js in the gnome-shell project... And what exactly is a sessionMode? I assume that those things are different sorts of it...

@ParanoidPanda right now i am somewhat more concerned with my lab report than with Gnome, so i probably cannot help you that much

Now that he is studying javascript , i am sure we're doomed. He'll be taking control of all the browsers and playing rickroll

Is c hard?

@HenryWHHack mostly not. Hardest part is the pointers and memory management. Otherwise , it's an ok language

It is low level more on the machine code side.

Yeah. You can actually directly work with memory addresses. That's why it's used with microcontrollers so much. It's very low level language

1:04 PM

asembly is lower than c

yeah . . . and it is pure pain

@Serg imagine writing in full binary :p

i've no idea how people were writing OSes in assembly back in the day

There was no other option

I think windows run assembly code

1:05 PM

@Zacharee1 <.< imagine flopping butterfly wings to alter ripples in atmosphere so that a single bit on hard drive flips

(xkcd reference )

And things weren't complex enough to require the use of full-on languages

@Serg yes

@HenryWHHack Everything on a computer has to at some point, but programs are in some C variant

and Java if you have it

@Zacharee1 Do you know assembly?

Oh God no

I barely know C++ :p

all I know is html,css and batch.

I used to know assembly for PIC18 microcontroller

1:08 PM

@Serg you would know what it's like then

yeah, i do . . .writing while loop to count up to 20 or something took us like 20 minutes

in C ? that would be less than a minute

C:

#include <stdio.h>
#include <stdlib.h>

int main(void)
{
	puts("Hello World!"); /* prints Hello World! */
	return EXIT_SUCCESS;
}

Assembly:

             	.Ltext0:
             		.section	.rodata
             	.LC0:

0004 BF000000 		movl	$.LC0, %edi
     00

Batch is worth less!

To do the same

XD OMG . . . .@Zacharee1 yes . . .

this should be a meme

1:11 PM

holly crap assembly uses more lines of color than c

yeah . . . .

color..?

assembly is much more colorful language XD

in fact, each CPU has its own assembly

so yeah, it's very colorful

It does not make sense python is just print ("Hello, world!")

Haha, throw up exception, omg, i am crying

I don't do that even for titles.

1:26 PM

@kos Do you add the parameter -enable kvm in qemu ?

@cl-netbox Yep. Without it was just painfully slow.

Anybody got experience with SNMP? - installing it in CentOS7?

@kos example : qemu-system-x86_64 -hda /media/cl/virtual/v-disk/fedora.qcow2 -cpu host -enable-kvm -full-screen -m 8192 -soundhw hda -vga qxl

@kos with this config it runs as fast as on bare metal

#define TRUE FALSE
    //Happy debugging suckers

oh lord

that's evil

@cl-netbox Hmmm ok, I miss -cpu host(and -soundhw and -vga, but I suppose that's not too relevant since I'm not using sound / 3D acceleration).

1:29 PM

@Serg Pure Evil xD

@kos just try it cpu is relevant gpu as well - for instance when you take std instead of qxl it is way slower

@cl-netbox Yeah I'll try -cpu for sure (now it's installing, I have to wait a bit). -gpu is relevant even without 3D acceleration?

//This code sucks, you know it and I know it.
//Move on and call me an idiot later.

@kos I think so ... performance wise ... I am really happy with kvm / qemu

@blade19899 letter 'e'
