08:39

@bwDraco Sorry, went to bed and didn't see that

rahuldottech

09:20

Okay, I've decided. I'm going to seriously give moving to GNU/Linux a shot.

5

Ubuntu is a good choice for a newcomer to the ecosystem but someone who is likely to be a (semi-) power user?

@bertieb What do you use?

bertieb

@rahuldottech Nice one!

I use Arch but it takes some getting to grips with

The best feature is the documentation

rahuldottech

@bertieb Yeah I think @Ave uses that too. Why do you recommend it over other distros?

bertieb

Closely followed by the packaging- system repos are very good, user repos (AUR) integrate very well with system stuff

It does only what I tell it to do

I moved to Arch from Crunchbang

Crunchbang got me to appreciate simple, lightweight distros

Bob

@rahuldottech That site does a pretty good job of it, actually.

All you really need is click-to-expand.

bertieb

And I found I could replicate what I had with Crunchbang with Arch

Ave

09:24

@rahuldottech repos are great, AUR is great, wiki is great

everything is up to date or close to up to date

rahuldottech

Cool. I'll give arch a shot, then. Thanks @ber @ave

bertieb

no problem

Ave

keep in mind

bertieb

Hope it works out for you :)

Ave

it doesn't have an installer.

bertieb

09:25

Be aware though that the default install only gives you a very basic shell

rahuldottech

wait wha

Ave

If you don't have internet, cat install.txt

if you do, wiki.archlinux.org/index.php/Installation_guide

I usually just open installation guide on my phone

bertieb

Also, actually follow that guide carfully

As in, don't be tempted to miss out steps

rahuldottech

Ah okay cool

Ave

also when you're pacstrapping you might also want to install networkmanager and wpa supplicant.

or else when you restart wifi will be impossible (without wpa supplicant) or painful (without both)

bertieb

09:26

Actually actually

Ave

(you can always boot back into bootdisk and mount it and install those tho)

bertieb

Here's a thought

rahuldottech

@Ave I'll keep that in mind

bertieb

Maybe install Arch in a VM first

Ave

yeah! that's a good idea

bertieb

09:27

So you can see what the process is like and what it gives you

Ave

also decide on which DE/WM you want

bertieb

Yup

Ave

and if you have no GPU or an AMD one, if you'll use wayland or x11

with nvidia you're locked into x11 sadly

bertieb

Nice side effect is that it gives you a good base for building other VMs from (I have a VM snapshot which is a barebones-ish Arch post-install)

Ave

I recently moved to wayland and while it still needs a lot of work, it's usable for almost all my daily tasks.

rahuldottech

09:29

@Ave Yeah, nvidia, although I don't really use the GPU so I could probably make do with just integrated graphics?

Ave

just use x11

bertieb

X11 should be fine tbh?

Ave

yeah

wayland is more of a masochist thing

bertieb

Hehe

rahuldottech

Cool, okay. I gotta go pay my orthodontist a visit rn, but I'll be back later.

Thanks again.

bertieb

09:30

Hope it goes well 👍

And really we should be thanking you

Not often someone asks you to evangelise GNU/Linux and your fav distro :D

Ave

I'll just toss some articles your way

wiki.archlinux.org/index.php/Dm-crypt/… < my FDE setup

bertieb

Usually it's "oh god please stop, I thought an arch was a curved stone opening"

Ave

you'll definitely need this wiki.archlinux.org/index.php/GRUB

and yeah this wiki.archlinux.org/index.php/General_recommendations

during pacstrap you might also want to install intel-ucode

aaaaaaaand if you want to steal my setup here's my dotfiles: gitlab.com/a/dot

feel free to @ me if you need any help

Journeyman Geek

lol

bertieb

ditto re help

I've had some painful Arch installs, but they were broadly i) didn't follow wiki ii) legacy vs UEFI weirdness iii) my version of Xen crashed on a kernel later than <something>

and the latter two of those aren't really Arch's fault

Other than being very up to date and making it a bit trickier to find older kernels, I guess..?

Journeyman Geek

09:43

I've been leaning slightly towards debian lately

ubuntu's NIH stuff has been a bit annoying

bertieb

Debian's grand too

Used that for ages

And Crunchbang was Debian-based, IIRC?

Journeyman Geek

yup

You do end up having older packages

Ave

I use sid for my BGP machine

Journeyman Geek

I run debian lxqt on my core duo ;p

djsmiley2k

11:31

JIM Y U DO DIS.

'COME DO OUR SURVEY'

'ITFULLYOUNODO.

@bertieb is /temp using mktmp?

If so, I don't think it reports 'being full' the same way a normal file would

bertieb

I unno

Lemme check fstab

no /tmp in there so... maybe?

djsmiley2k

@rahuldottech The documentation for Arch is on par with, if not better than Gentoo's

And that's saying something concidernig how much of a fan boy I am

My issue is any distro, which doesn't easily allow me to setup packages they don't already have

So centos, debian, ubuntu can all diaf, even tho I do use them.

@bertieb ls -lah /tmp ~?

without ~

bertieb

@djsmiley2k Buncha temp files?

anything in particular I'm looking for?

Journeyman Geek

@djsmiley2k meh

Actually I run ubuntu cause its easy to find third party repos

bertieb

Also can't you compile debs for debian-likes?

Slightly more painful than the beautifully-automated AUR

But at least those would integrate with apt

Journeyman Geek

11:40

Actually for one offs?

wiki.debian.org/CheckInstall

djsmiley2k

11:53

:D

@bertieb hmmm not sure, one mo

bertieb

@djsmiley2k It's not critical, this is purely for curiosity as to why bus error

I can live without knowing the answer :D

djsmiley2k

12:09

yeah but I MUST KNOW

MUUUUUUUUUST

If only there was a site...

Q: numpy.memmap: bogus memory allocation

I have a python3 script that operates with numpy.memmap arrays. It writes an array to newly generated temporary file that is located in /tmp: import numpy, tempfile size = 2 ** 37 * 10 tmp = tempfile.NamedTemporaryFile('w+') array = numpy.memmap(tmp.name, dtype = 'i8', mode = 'w+', shape = size...

A very quick overview tells me ffmpeg tried to create a sparse file of size X, where X exceeded your physical storage

it only errors once you tried to write more data than can be allocated...

> Indeed, if I introduce the following in my code:

for i in range(size):
array[i] = i
I get the error after a while:

Bus error (core dumped)

or you told ffmpeg to use a mktmp file you'd created

or a loopback device

Which is why you get the bus error, technicall the device your writing to has space.

bertieb

12:33

@djsmiley2k Why did VLC error out?

ffmpeg-concat wrote a bunch of raw pixel data frames to /tmp, filling it

then it errored out with a bus error

launching VLC caused a bus error too

(I didn't try other programs)

removing the temporary frames caused things to work again

shrug

@ave where should I text you?

Ave

@rahuldottech telegram works.

I wanna learn perl

I don't know why

But I really do, for some reason

Journeyman Geek

make it so

rahuldottech

I will, as soon as I'm finished with the current projects that I'm working on

bertieb

I used to use perl

I thought I enjoyed it

Then I discovered python

Pretty sure there's an XKCD for that exact scenario

Eh, alt text for 353

s/alt/title/

> I wrote 20 short programs in Python yesterday. It was wonderful. Perl, I'm leaving you.

Journeyman Geek

14:59

@bertieb then you took an arrow to the knee?

bertieb

@JourneymanGeek if by "arrow to the knee" you mean "motorbike chain to the fingers" then... yes

Burgi

To generate #1 albums, 'jay --help' recommends the -z flag.

bertieb

something something, "run jay with the -z flag"?

Oh, that includes the title text

I was close

Burgi

i've reread all the xkcds about 4 times over

djsmiley2k

@bertieb bad ending to a file causes everything reading it to derp?

file says 'I'm 1Tb!' you only have 200mb on disk

bertieb

15:08

@djsmiley2k VLC wasn't reading the files- it was just dumping core after/on loading

So still dunno

Could probably replicate by filling up /tmp again

And doin' a heckin' gdb trace

But, eh, #effort

djsmiley2k

15:36

@bertieb no longer true

print("Hello World")

iirc

I don't foo enough

Where foo is any number of programming languages I've touched.

bertieb

15:50

@djsmiley2k Aye, on python 3

My bad. UV400 120gb is same price as A400 240gb

bertieb

Holy (removed)'s, Batman!

rahuldottech

So I really want this for my new laptop: amazon.in/Samsung-500GB-Internal-Solid-MZ-76E500BW/dp/…

But it'll set me back two month's pocket money

hard. decision.

bertieb

(other Rahul to Rahul: buy the 2TB version)

Did I just get 1903? I was sure I was up to date already

But the Windows background is a much brighter shade of blue

Windows folks, where do I see wupdate history?

"View your update history", you say

That sounds complicated

I'm sure I had some of these "new features"

like the emoji one using Win + . (Rahul's favourite feature, natch)

"Make your pointer easier to see"

0o

Oh, mouse cursor

Pretty sure that's been in there since at least '95, if not earlier

All I can be sure that's new in this update was a change to wallpaper

Anyone here uses Xen Orchestra? What could be causing the discrepancy in this image?

djsmiley2k

real vs sys cache

notice the bar is 2 green bits full? then blue then orange/yellow?

That Brazilian Guy

@djsmiley2k Thought so, but free -h returns this:

              total        used        free      shared  buff/cache   available
Mem:          7,8Gi       262Mi       5,9Gi        24Mi       1,6Gi       7,3Gi
Swap:         3,8Gi          0B       3,8Gi

djsmiley2k

hmmm that shared

281MB Free?

That Brazilian Guy

And the Xen Orchestra mouseover says 2.06 GiB(notice the "GiB")

djsmiley2k

huh weird

That Brazilian Guy

19:50

@djsmiley2k Ops. Misaligned. Fixed.

djsmiley2k

ah ok

That Brazilian Guy

So, 1.61 Gi + 262 Mi != 2.06 GiB. Something's amiss.

Although your observation makes sense.

djsmiley2k

262 + 24 + 1600 == 2.06Gib ?

+ 'overhead' ?

1896 hmmmm

That Brazilian Guy

Anyways I need to have the "used" info on a chart. There's a zabbix server somewhere. Maybe I can install a Zabbix agent to collect this data and request a user account on that server.
