what version are you using?

Oh i only see this"

sudo apt-cache search libweston
libweston-1-0 - reference implementation of a wayland compositor (shared libs)
libweston-1-dev - reference implementation of a wayland compositor (shared libs)

@user1770201 only in Bionic ... you aint using 18.04 it seems ;-)

So I have to build this package from source?

How do I see which version of Ubuntu I'm running?

well i would not run bionic yet on bare metal

@user1770201 lsb_release -a

I'm running 16.04

@user1770201 I would start with trying the DEB from bionic or from debian

if you REALLLLLLLLLLY need it

6:04 PM

yep thats when you do a packet search then xenial

I do need it

do it in a vbox install 1st

test it 1st before you install it in your OS

I know what I'm getting myself into :)

How can I install this on my OS?

@Rinzwind coughs packages.ubuntu.com/bionic/libweston-3-0 have you seen all the dependencies?

this surely will be an adventure

@Videonauth yeah I saw that >:-D

and debian is sid unstable

6:06 PM

not sure if this will work only by downloading the deb file

@user1770201 I soooo would not want to need it if I was you :-D

@user1770201 well you can start by downloading all the deb files, means the weston.deb file plus all its dependencies, plus their dependencies and then you start with dpkg -i weston.deb and see if it fails to install, if yes dpkg -r weston.deb and dpkg -i dependenciy.deb and rinse and repeat

But thats quite a change you do on your system and its quite unstable and may break everything

rinz and repeat :=)

@Videonauth I would install vbox, Ubuntu in it and then start messing around with that.

@user1770201 ^this

..... and since you can backup a vbox instance and just put it back to continue from where it all worked

Q: There are active mods here?

6:18 PM

thats how I try to recreate the OPs bugs when trying to answer questions ;) no way I'm messing around with my actual installation.

just checked about half of the dependencies, on 17.10 you might be able to install it with gdebi

but that might be because 17.10 is actual not very different from 18.04 were only a few days after feature definition freeze

and alpha1 is still 29 days in the future

I've requested my profile deletion a couple of months ago and I didn't receive any response from staff. I've tried through "other topic" and no response. Is there any reason to don't let me delete my profile here?

support

to be honest i rather would go and grab the upstream source and build it

@terdon ^^

@dessert EEEEKS your pointing at me :P

6:42 PM

@Videonauth one ^ is pointing on the last post, two ^^ on the next-to-last I'd say – or not?

Kaz Wolfe

^^ will always be an emoticon to me

@dessert Well you havn't seen me in real life, there you would need at least ^^^^^^^^ to point at something behind me

:P

@Videonauth lol!

@dessert Yes?

@terdon Wanted to point you to meta.askubuntu.com/questions/17505/there-are-active-mods-here/…, but now I answered it myself… have a look

6:51 PM

@dessert Mods are notified of all meta posts. There's no need to ping us in chat, thanks.

Don't really know what to tell that user anyway. It's an SE thing. We don't handle thee requests.

@terdon Wow, and you're a multimod – don't you drown in this flood of pings and messages?

@Videonauth Sorry, I was away visiting mum in the hospital...

CC @Terdon...

@dessert Why do you think I've often asked people not to ping me when they're just referring to me or just to say hi etc? :)

Yo Fabby!

@Fabby Hope she will be well soon :)

@Fabby Oh, wow. Serious?

6:53 PM

We don't know what's wrong, that's the problem...

Ouch.

My Dad went through something like that a few years ago. It's no fun.

I'm sorry to read that - I hope they determine what's going on quickly

Yeah, well, I hope it's not dementia...

Anyway, I have to go back to work: meeting in 6 minutes. TTYL8R

7:27 PM

@ThomasWard I asked if you'ld used or were familiar at all with an nginx+sanic/japronto+asyncpg stack

@NathanOsman nice, you should definetively look more into PBR materials for rendering

7:42 PM

@dessert Several weeks.

@Videonauth That's pretty.

want to have the blend file?

Sure!

@NathanOsman videonauth.dyndns.org/download/render/cloth-showcase.tar.xz

Thanks.

7:56 PM

no problem, youre welcome

just got Blender today

@ThomasWard Don't worry, already got it. (stackoverflow.com/questions/5506110/…)

@NathanOsman take a look at the setting which are saved with the file they might interest you

not sure if i had there already the higher dynamic lighting routine setup or not

@TheWanderer let it run several weeks and it will be super smooth

9:06 PM

wow, only a few minutes having a link to a file in this chat and soon the robots for scraping sited already have downloaded it despite having forbidden that directory for robots -.-

deleted the file now

sorry for everyone else later on reading this and wanted the file, ping me if that is the case

Nope.

That's the good news...

Wonderful example of "How to handle your question the worst possible way" --> askubuntu.com/q/983208/522934

90... :D

Me one or so...

:) well but i would gladly swap with you hehehe, a job and income seems far better than reputation ;)

Which job do you want? I'll ping you next time there is an opening in EMEA...

EMEA?

9:53 PM

Network? (IOS) Compute? (VMWare) Storage? (EMC) Pre-Sales System Architect?

Europe, Middle East, Africa.

We ave people from Dubai to Hamburg.

well talk bout that next weekend, i have no clue what i could apply for (in home office)

and from UK to 30 Km from the Czech republic.

All of the above. (except System Architect: he has to drive to customers)

@Fabby that would be a propblem since i have ni drivers license

Good night! I've had it for today!!!!

sleep well

9:55 PM

@Videonauth :D ;) :D

OH MY GOD UBUNTU

17.10 IS SO UNSTABLE

We also need DCOps, but they're in the UK only and they don't have Home Office jobs.

@TheWanderer woot ?

how ? its running very stable on my machine

I can't open ANY system monitors

my AVD just froze and I can't close it

ps freezes the terminal

top freezes the tetminal

killall freezes the terminal

[Ctrl][Alt][F1] kill -9

9:57 PM

Chrome freezes for about 2 minutes when I first open it

I can't reboot or shut down

or sleep

@Fabby would send him to the login screen :P

Jesus Christ

ctrl+alt+f3 if

@TheWanderer [Alt][SysReq][Alt]REISUB

F7 is the GUI

9:57 PM

/shrug

@Fabby I've rebooted many times

@TheWanderer wanna make a bet on it?

;)

It's what I'm in right now

A: How do I switch between console mode and GUI in 17.10?

48

The actual used tty consoles have changed around with the introduction of Wayland and 17.10. Now tty1 always contains the login screen, and tty2 contains your actual loaded session. So use Ctrl+Alt+F3 up to Ctrl+Alt+F7 for getting to an actual unused tty and use Ctrl+Alt+F2 to go back to GUI. F...

2

And now my GUI is frozen

I can't even switch TTYs without everything freezing

9:59 PM

Wayland or Xorg?

Whatever kde uses

thats really weird i have for sure the oldest pc of all people in this room and on my machine it works flawlessly

by default they all use Wayland

however REISUB always works

So does holding down the power button

10:01 PM

that is hard wired behavior

yepp but holding down power is not the way to go if you use a journaled file system

@Videonauth Starred! I didn;t know!!!

py.checkio.org really is a great example of gamification, and a fun way to learn python :>

@Fabby that is at least for ubuntu-vanilla-gnome and ubuntu

/shrug

Good night! shuting down NOW!

10:23 PM

Back on my Ubuntu machine.

@SergiyKolodyazhnyy Hey, your askubuntu.com/q/739654/295286 script doesn't seem to work...

How do I debug it?

(running on 16.04)

what does not work on it?

does it simply have no effect or does it throw an error?

it doesn't save the brightness.

if I run it in a terminal,

it doesn't work neither...

Lemme turn on debugging first.

(why didn't I think of that???)

(too tired)

:)

Q: System halts after Apache crash

ah as a user it doesn't work.

Lemme try root

ah!

Lemme change ownership of the save file!

You're not a sheep, you're a wolf!

Thought you were sleeping

he is, its his superficial AI using his computer right now ;)

@TheWanderer Nah, I'm now on my private machine running Ubuntu...

@Fabby Hey, there. Looks like you got it resolved already, right?

10:43 PM

@SergiyKolodyazhnyy how are you ?

@Videonauth I'm alright, but could use a bath. :)

Nope...

Doesn't seem to store stuff. now running it with bash -x

I've chmod ed the file so that everyone has RW access...

didn't make a difference

root@fab-ux-predator:/usr/local/bin
# bash -x keep-brightness restore
+ ARGV0=keep-brightness
+ ARGC=1
+ main restore
+ local DATAFILE=/usr/local/bin/.last_brightness

+ restore /usr/local/bin/.last_brightness
+ MAX=11
+ LIMIT=1
+ VAL=5
+ '[' 5 -lt 1 ']'
+ echo 5

@Fabby alright. I'll debug it later tonight. Are you using lightdm btw ? Because it's meant to be used with that

I'm on Unity 16.04, so AFAIK, yes...

Ah, very well, same as what I use. OK, I'll figure out what's going on

10:49 PM

the only thing I did was copy it in /usr/local/bin instead of the local user's bin and it worked on my old machine...

# ls /sys/class/backlight/acpi_video0/
actual_brightness brightness max_brightness subsystem uevent
bl_power device power type

And I have nvidia driver...

/shrug.

Oop, found one bug

:D

if [ "$1" = restore ]

restore is a function

Should be using "$(restore)", I think

$ python -c "print(abs(-2.2-10.2))"
12.4
$ python3 -c "print(abs(-2.2-10.2))"
12.399999999999999

can anybody explain this weird behaviour?

Floating point error.

10:52 PM

rounding and no rounding and the usual float error

Means Python3 is more precise.

what he said ----^

Typical.

Always round when using floating point.

but round() doesn't help!

>>> print(round(abs(-2.2-10.2)))
12

@dessert docs.python.org/3.6/library/decimal.html

print(round(abs(-2.2-10.2),1))

or decimal type...

Q: Limiting floats to two decimal points

913

I want a to be rounded to 13.95. >>> a 13.949999999999999 >>> round(a, 2) 13.949999999999999 The round function does not work the way I expected.

python floating-point rounding precision

10:57 PM

Djeez, python sounds like Microsoft basic!!!

nah its actually fine if you get the hang of it

those examples given in this answer are for python2 i guess

ok, thank you guys

@Fabby Except Python is still used and more readable

:p

print(f'{round(a,2)}')

^ @dessert for python 3.6

or down to one digit after the floating point

@SergiyKolodyazhnyy basic must still be used today.... Lemme get some stats...

11:01 PM

the only thing i cant yet so really get the hang of are the lidt etc initalizers

I'm sure it's still used somewhere. There's plenty of legacy systems around. Just poking fun

I had to take Visual Basic once as part of my engineering program. I know, go figure

Nov 2017 Nov 2016 Change Programming Language Ratings Change
1 1 Java 13.231% -5.52%
2 2 C 9.293% +0.09%
3 3 C++ 5.343% -0.07%
4 5 change Python 4.482% +0.91%
5 4 change C# 3.012% -0.65%
6 8 change JavaScript 2.972% +0.27%
7 6 change Visual Basic .NET 2.909% -0.26%

>>> data = [1 for x in range(8)]
>>> print(data)
[1, 1, 1, 1, 1, 1, 1, 1]

Python only 1.5 percentage points more popular than BASIC!

i wonder where the rest of the 100 percent is in that ratings table :)

11:06 PM

COBOL, ADA, SMALLTALK, ...

Tons of languages out there taking very little

i wonder why c and c++ are not leading tho

tiobe.com/tiobe-index

but again with all that android crap java gets pushed

@Videonauth because they're specialized languages. C is now mostly used for OS and MCU stuff. Besides, it's easy to shoot yourself in the foot with those.

@SergiyKolodyazhnyy so they are like linux ;)

11:09 PM

Well, Linux kernel is all C, so yes

There's a lot of assembly in there too.

Also assembly, yes

But I'll stay away from that. I had enough assembly in my MCU class

Maybe this winter break I'll go back to refresh my C knowledge. I am going to need it for next semester.

I'm outta here: in <8h alarm goes off!

G'night y'all! Unlike Fabby I actually am leaving. Enough python for one day. ,)

11:16 PM

@SergiyKolodyazhnyy did you see that i rolled back this question? askubuntu.com/q/982302/522934

Oh

bad timing

happens :)

Sleep well, Fabby. Don't let the Vorlon bed bugs bite

Ah another douglas adams fan ;)

@Videonauth I saw that but deleted the comment only now. Thanks for the rollback

11:18 PM

i hope this answer stay like it is now

@Videonauth Fabby is. I'm not much of science fiction aficionado

Well it was my first Sci-fi book I have read in my life :)

To be fair, whoever is OP's teacher, they asked a kinda unreasonable thing to implement

yep, unless they actually teached all the knowledge before giving that assignment, but even then it is hard

Exactly

@SergiyKolodyazhnyy yep and it downloads all sorts of file, but well their webpage does not disclose for whom they scrape and its not following rules, so new server rule: if this ip shows up drop connection ;)

Probably a good idea

yep, they not even get a 403 served
