custom server motherboards from a manufacturer, $491 for what i've got in mind (dual 8-core Xeons, 128GB Hynix PC-12800R server RAM (16x8GB)), the rest of the components are second hand or I already have around

has the power supply, and drives for data storage around, which saves about $150 - $250

Given that my current i5-6200U/Geforce 940M/12GB RAM/128GB SSD/1TB HDD laptop costed 777€, I'm even more envious now.

Most stupid comment ever:

@ByteCommander laptop vs. server/workstation machine.

@Alcuin Arundel Why is it so hard to create my own screen saver in ubuntu. In windows I can write in win32 but ubuntu just sucks. — LuckyAli 4 mins ago

Arne N.

He has to be a complete idiot right? posting this on a ubuntubased forum with full of ubuntu fans lol

Thomas Ward

laptops always run pricier

@ArneN. Lets not call names

We get a lot of these.

Byte Commander

yeah, but still.

Arne N.

12:09 AM

Thomas Ward

They usually all get closed. or they're far more angry and get offensive flagged

and sniped.

Arne N.

Yeh

Android Dev

@ThomasWard - Is all software in the repos FOSS?

Serg

Instead of politely asking "How to write screensaver in Ubuntu" , he goes into rant . . . . that tells something about OPs character . . . and intellect

Android Dev

@ThomasWard And get you less performance.

Thomas Ward

12:11 AM

@AndroidDev Indeed. Hence moving all the stuff to hypervisors and VMs. Makes things go WHEEEEEEEEEEEEEEEEEEEEEEEEEEEEE!

@AndroidDev does this answer the question?

Android Dev

@ThomasWard You could load the entire Vdisk in RAM! Ubuntu would boot in .00000001 seconds!

Thomas Ward

in theory, yes. in reality, not really for what I need.

Serg

@AndroidDev Short answer: no

Thomas Ward

@AndroidDev Long answer: No, and there's multiple pockets for different types of 'restricted' software licenses, etc.

Arne N.

Just a quick question does someone have a SSD with ubuntu?

Byte Commander

12:15 AM

Uhm... I still don't get what he actually wants

@Byte Commander I know it's not a programming language. It's an API. But, I can use that API to create screen saver but ubuntu sucks no way to create screen saver from scratch. No bit-by-bit screen saver generation. — LuckyAli 4 mins ago

Android Dev

@ThomasWard But if I apt-get install a program on a vanilla install, is it FOSS?

@ByteCommander To annoy us with his rant.

Byte Commander

requests a resupply of downvotes

Thomas Ward

@AndroidDev It depends on the software you're installing.

Android Dev

@ArneN. I'll be helping a friend install to a 950 Pro next week :)

@ThomasWard <sigh>

Byte Commander

@AndroidDev Only if it's from the main or universe repo IIRC.

Thomas Ward

12:17 AM

@AndroidDev Not the answer you're expecting, I know. But answer me this: if I run sudo apt-get install nvidia-graphics-drivers-352 is it open source?

Byte Commander

@ArneN. Yes. Why?

Arne N.

@AndroidDev Im curious how fast ubuntu boots on that :p bcuase i just have a default HDD and it boots in like 20seconds. With a SSD i'll probally be amazin XD

How fast does it boot up? @ByteCommander

Byte Commander

Let me test... :)

Arne N.

hahahha :p

Thomas Ward

@AndroidDev Versus, if I install apt-get install nginx is it open source?

Byte Commander

12:17 AM

Wait, no.

Thomas Ward

The nVidia binary drivers are not.

Android Dev

@ThomasWard - So what prevents someone from writing a malicious Linux application that first infects your machine, and then encrypts your /home DIR three months later?

Byte Commander

systemd-analyze logs that anyway

Thomas Ward

@AndroidDev You're asking the wrong guy the question.

Byte Commander

$ systemd-analyze
Startup finished in 4.244s (firmware) + 3.090s (loader) + 2.746s (kernel) + 8.295s (userspace) = 18.377s

meh...

Thomas Ward

12:19 AM

@AndroidDev I can write an obfuscated Python code and give you only the compiled code to run and execute. It can be coded to do something nice but then torpedo your firmware by writing bogus data to it. YOu'd never know until you dug into the software and decompiled it.

You also state 'writing a malicious application'

you don't say "add a malicious application to the repository'

we have a question on this you know

Byte Commander

$ systemd-analyze blame | head
          9.057s snapd.refresh.service

Android Dev

@ByteCommander @ArneN. I'll report the times from my friend's machine after I help him install it. That 2.2GB/sec read speed is pretty sweet!

Byte Commander

Why does snapd take 10 seconds although I never ever installed any snap?

Arne N.

Sure :p

Byte Commander

Can I get rid of that one?

Arne N.

12:20 AM

wait

Android Dev

@ThomasWard Could you link me to it?

Byte Commander

@AndroidDev 2.2GB/s O.O

$ sudo hdparm -t /dev/sdb

/dev/sdb:

Q: At 10k rep, can you flag still?

Once you reach 10k rep, which I think is where you can review flags, can you flag or not? Because it seems pretty silly if you can...

Android Dev

@NathanOsman Of course, compare that to L1 CPU cache, and 5GB/sec will seem like nothing.

Q: Apt-get update/update manager downloading slow

I am running Linux Mint 18 and my sudo apt-get update/update manager speeds were fine until today. Now they can't even get past 60 kiBs, I have tried changing servers but it was in vain, as all of the main mint servers are the same slow speed or with the base ubuntu servers just unreachable. When...

ubuntu networking linux-mint apt software-updates

Nathan Osman

Three servers spread across North America in a CoreOS cluster... booting time...

@UbuntuQuestionsonU&L I instinctively went to flag that and then realized it was on U&L.SE.

Thomas Ward

heh

@NathanOsman you know that it needs edited to remove the Ubuntu tag then

Android Dev

@NathanOsman OwnCloud?

Nathan Osman

12:41 AM

@AndroidDev Nope, these are CoreOS servers. They'll be running Docker containers.

The neat thing is that the containers are distributed across the servers and if a server disappears (hardware or network partition) the service is started on one of the remaining servers.

That's the theory anyway.

Android Dev

@NathanOsman I really do need to look into Docker.

@NathanOsman Like AWS EC2?

Nathan Osman

Digital Ocean - but AWS would work the same way.

CoreOS works on both.

Android Dev

Hmmm.

Nathan Osman

And I've used it on both.

Digital Ocean is just a bit cheaper.

Nathan Osman

I think this is Digital Ocean's problem.

The other two datacenters work.

Serg

I should do some serious tuning to my laptop . . . .

Nathan Osman

@Serg CoreOS doesn't have nano :(

So I'm stuck with vim.

And no clue how to use it.

Arne N.

can you not compile it then?

Serg

@NathanOsman I'm at your assistance if you need :D

ƎpᴉʇʎXD

1:27 AM

O-O

Arne N.

vim is not that hard when you get used to it

Nathan Osman

@ArneN. CoreOS is Gentoo based.

Arne N.

ooh

Nathan Osman

@Serg So I opened the file. Now how do I edit a line? :D

Serg

vim is like paint brush. If you click "Insert" or "i" , you start inserting stuff

It's like you put brush on canvas

ƎpᴉʇʎXD

1:28 AM

:D

Arne N.

and then you press escape to enter command mode

ƎpᴉʇʎXD

or pencil lines

Nathan Osman

@Serg And if I remember correctly, ESC exits line edit mode?

Arne N.

where you can do :wq (write quit) and so on

ƎpᴉʇʎXD

where the serious stuff happens >:D

Nathan Osman

1:29 AM

@ArneN. Ah, okay.

Serg

YEs, If you press escape - you take off the brush from canvas . In that mode you can press ":" and add letters for particular commands

:ｗ for writing ( save file)

:wq write and quit

Nathan Osman

Okay, thanks.

Serg

:d delete (whole ) line

Nathan Osman

That should be enough for basic editing.

It beats using cat to stuff input into a file :P

Arne N.

its a bit weird to get used to :p

Serg

1:31 AM

If you ever get stuck , ping me

Nathan Osman

Cool, thanks.

@ArneN. You can say that again :D

@ArneN. wat O_O

Is it a Moto or something

Nathan Osman

I didn't know that was possible.

Serg

so i have my 5 port switch. i can use laptop as gateway, and connect up to 4 other compooters to it. Time to get Kali and start nuking stuff ?

Zacharee1

@Serg yes

shouldn't you get a router though, if your laptop is the internet connection?

Arne N.

@Zacharee1 wait we are talking about phones right?

Serg

em . . . . probably

Zacharee1

1:39 AM

yeah

Arne N.

I have a Samsung galaxy core prime (480 x 800 pixels (~207 ppi pixel density)) xD

Nathan Osman

I wonder how expensive it would be to get a magnifying lens for my smartphone. At least 25x would be nice. Maybe even 100x.

Serg

among other things, i should throw away bunch of stuff in my room

Zacharee1

@ArneN. ew :p

ƎpᴉʇʎXD

i have a samsung s3 mini

Zacharee1

1:41 AM

@NathanOsman you mean for the camera? I'm actually curious how well those things work

Nathan Osman

Samsung is a two-tier company. Their cheap phones are junk but their pricier ones are pretty decent (minus TouchWiz, of course).

@Zacharee1 Yeah.

Serg

like, i have all sorts of boxes and bags and books. but reall i only need a fraction of it all

Nathan Osman

@Serg Welcome to my world :)
