So calming.

Nathan Osman

That is really cool.

I could listen to that for hours.

Seth

@NathanOsman Same. I could go to sleep listening to that.

Nathan Osman

I might even try that.

Heck, I could stare at it for hours.

Does the music get faster during more busy times?

I mean - I'm not expecting too many commits late Friday night :P

Seth

Now I'm curious!!

It's so. calming.

so... got unifi equipment finally for real :D

i now have wifi a third of a mile from my house

Nathan Osman

Niiice.

Kaz Wolfe

also their DPI is scary

Nathan Osman

I have six antennas on my router and I can get WiFi outside.

Which may not sound all that impressive.

Until you realize I'm in an apartment with 30+ other APs.

good morning

we have currently a snowy winter landscape out there

sadly it might not be enough to make the snow stay

Seth

@NathanOsman listen.hatnote.com/…

Nathan Osman

I should check the temperature here.

@Seth That's a bit less... melodic to me. But certainly faster.

Seth

@NathanOsman Indeed. I think the speed is what ruins the melody. That and they're using slightly different sounds

Nathan Osman

It's dipping below zero just before sunrise.

As you can see, it's kinda cool indoors too :P

@TheWanderer Of course another German, what did you think? Who cares for Poland nowadays…

dessert

9:47 AM

Is it really true AU doesn't have a question “How to treat filenames with spaces?” or am I missing something here?

Videonauth

how do you search?

dessert

@Videonauth askubuntu.com/search?q=file+space+is%3Aquestion

Videonauth

use this google.de/… it is quite more accurate and complete

@dessert ^...

dessert

@Videonauth I'll stick to startpage, but that's the same thing – you're right, it gives better results. A shame… startpage.com/rvd/…

Seems true that we don't have a canonical question about it, I think I'll add one explaining the most important things. This one gets near it, but misses single quotes and the explanation what they do differently – and probably won't get found by somebody searching how to treat filenames…

dessert

10:20 AM

Hahaha, ls doesn't even display a newline in a filename properly:

$ touch "$(printf "newline\nfile")"
$ ls
newline?file  space file

cl-netbox

1:57 PM

Hello :)

Thomas Ward

2:16 PM

@dessert it's not supposed to. No filename should have a new line in it. Ever. Regardless of the environment.

not in Windows, not in Linux, not in Mac, not in ObscureOddballOSFromTheDarkAges, not anything.

any filename with such an escape character in them is invalid, and needs to have its filename sanitized before use

because it causes non-standard behavior to keep it in there.

I ran into this with a particularly nasty piece of home-grown code to handle emails and filenames got mangled because of the chaotic piece of crap that Exchange is.

so i've had to sanitize filenames ever since in my code. Which is now second nature to me, mind you, but...

same point.

gansub

I am using 16.04 LTS. But why is my linux version 4.10-0-42?

can i upgrade to a higher version?

Thomas Ward

@gansub Mind doing an apt-cache policy linux-image-generic for me?

and including the output here?

gansub

linux-image-generic:
Installed: (none)
Candidate: 4.4.0.103.108
Version table:
4.4.0.103.108 500
500 http://in.archive.ubuntu.com/ubuntu xenial-updates/main amd64 Packages

4.4.0.21.22 500
500 http://in.archive.ubuntu.com/ubuntu xenial/main amd64 Packages

Thomas Ward

right...

gansub

so ?

Thomas Ward

2:30 PM

@gansub in theory you can install up to 4.13.0-19 but I have no proof that it'll work proper - that's just what I see in the repositories

gansub

i see

if and when i upgrade to 18.04 will it sync ?

Thomas Ward

you can get that with sudo apt-get install linux-image-generic-hwe-16.04-edge if you want it now

gansub

why am i so behind ?

Thomas Ward

@gansub not sure. It should put you on the standard kernel for 18.04, but I'm not sure what that is off-hand at the moment

@gansub you aren't.

not really.

gansub

well may i know yours ?

Thomas Ward

2:32 PM

except that...

Q: Why don't the Ubuntu repositories have the latest versions of software?

Why are packages in the official Ubuntu repositories older than the latest (upstream) versions from Debian Sid, PPAs, the authors, etc.?

^ this is relevant (kernel too)

Videonauth

@ThomasWard 4.14.0-17

Thomas Ward

@gansub i'm not on the edge packages, standard 4.4.0-101-generic

gansub

so you are ahead of me ?

Thomas Ward

@Videonauth could change if there's an evil

@gansub no, i'm actually behind you. I don't upgrade my kernel to have latest HWE usually, or at least, not the edge HWE kernels

Videonauth

well thats the kernel it upgraded today to

Thomas Ward

2:33 PM

because older hardware.

gansub

who here is using 18.04 ?

Videonauth

/me in a VM

Thomas Ward

@gansub nobody if they want to get support from askubuntu.com

otherwise just us people testing it in VMs or containers.

gansub

i see

so on that version of Ubuntu what is the version of linux

Thomas Ward

askubuntu.com does very limited support for the 'in development' release, at least until it is released, then we provide standard support.

@gansub 18.04? should be 4.14.0-17

at least, rightnow.

gansub

2:34 PM

so that is ahead of mine ?

Videonauth

Ubuntu 17.10 on proposed branch: Linux NEXUS-ONE 4.13.0-19-generic #22-Ubuntu SMP Mon Dec 4 11:58:07 UTC 2017 x86_64 x86_64 x86_64 GNU/Linux

not sure but i think the normal branch is at 4.13.0-16

gansub

last time i upgraded from one LTS to the next i lost my data

i had to do a reinstall from scratch hopefully the 16.04 LTS to 18.04 LTS will be smoother

i think i had a lot of PPAs

this time no PPA at all

plus no Intel compiler all gcc or gfortran

Videonauth

there is a reason backup programs exist :)

gansub

but i do not like PPAs

cl-netbox

@ThomasWard why edge Thomas ?

gansub

2:41 PM

they mess up

Thomas Ward

@cl-netbox latest package version in the repos.

that's all.

i'm not using it :p

cl-netbox

@ThomasWard sudo apt install --install-recommends linux-generic-hwe-16.04 xserver-xorg-hwe-16.04

Thomas Ward

i know how to upgrade my kernel thanks :p

i'm not the one who was asking how to get a newer one

that was @gansub

cl-netbox

@gansub sudo apt install --install-recommends linux-generic-hwe-16.04 xserver-xorg-hwe-16.04

gansub

do you agree PPAs mess up upgrades @ThomasWard

cl-netbox

2:44 PM

@ThomasWard I know ... just mentioned it because you suggested to install the edge (beta/dev) version to @gansub :)

Thomas Ward

@gansub considering I maintain 15 separate PPAs for separate types of software that replace standard-repository versions with updated versions that I've personally made sure work?

the answer to your question is "it depends on the ppa"

@cl-netbox let's not berate me today, i'm still waking up nor did I directly say they should use it. They asked what the newest available kernel was, I told them what's in the repos. I never explicitly said "This is going to work" :P

gansub

i think a PPA is a non standard way to change the repository

Thomas Ward

@gansub you're entitled to your opinion, but given the rules around how releases get pretty version-locked after release, it's the only way other than compiling thingsi from source to get newer versions of a given piece of software

cse in point the nginx repos

but i maintain those PPAs and the nginx package in ubuntu so...

cl-netbox

@ThomasWard good morning Thomas ! :) have a huge mug of coffee ... sending it over the ocean :D

gansub

so i do not use QGIS which is the most popular open source GIS software because it requires a PPA

Thomas Ward

2:47 PM

@gansub that's your choice. Others might use the PPA.

yawns

gansub

i remember on 12.04 i had to use PPA for installing google-earth

and then when i upgraded to 14.04 LTS lost everything and reinstalled from disk

cl-netbox

@Videonauth that is in stable -> 4.13.19 ... good afternoon to you ! :)

gansub

there was a guy here i forget his name but he remote trouble shooted for 3 hrs

Videonauth

ah ok, i never know exactly which kernel is now in stable, like i said im always on proposed

gansub

to remove that PPA.w e finally gave up

Thomas Ward

2:51 PM

@gansub because one ppa broke your system doens't mean that all PPAs are bad. That's all I'mma say on the matter, because if I want to have a nonstandard package version in my system, I usually am backporting it myself :P

gansub

@ThomasWard are you a kernel developer ?

Thomas Ward

i don't mess with the kernels. That's the one thing I leave alone.

because I usually don't need the newest Linux kernel for things

gansub

but you are a systems developer ?

i am an application developer

Thomas Ward

define 'systems developer'

i'm a professional linux systems administrator and IT Security professional/specialist.

cl-netbox

@gansub he is the master of chaos, evil and disaster (recovery) ... :D :D :D

gansub

2:53 PM

one who makes a lot of kernel calls

Thomas Ward

@gansub i'm nto a software developer. And if I'm making kernel calls I'm not making them directly, I'm using well-developed libraries which do that for me. :P

that wasn't my initial point

gansub

right. i do that as well i.e use well developed tested libraries

Thomas Ward

my point was that messing with the kernel has its own inherent risks

this is why if I'm going to go fussing with the kernel I'm not doing it on my main system

i'mi doing it in a dedicated system so I dont' fubar things

or in VMs which won't impact the primary machine

the same goes for testing programs and such in sandboxes.

or analyzing a particularly nasty piece of malware in a sandboxed, isolated lab environment

gansub

i recently installed a heavy duty software from source one that uses a lot of external libaries including Qt

vapor.ucar.edu/internal/downloads/source-distributions is probably the toughest and hardest install from source i ever did

that Qt compile was something

Thomas Ward

you've basically just described Arch.

this is why i'm not a fan of building from source code.

at least, if I can avoid it.

gansub

2:57 PM

you probably use binaries ?

that is what Support told me - we do not support compiing from source code. use the binaries

Videonauth

@ThomasWard dint you want to say gentoo ?

Thomas Ward

@gansub depends on the software, and specific cases.

there are pieces of software which I compile from source, but it's rare.

and it's usually Java files that end up as JARs

gansub

well Tom it is usually very easy

Thomas Ward

@Videonauth I meant to say (‡▼益▼)

and don't call me Tom

only my girlfriend, family, and close friends can call me that.

gansub

just run ./configure then make then make check then make install

ok @ThomasWard :)

Thomas Ward

2:59 PM

... okay at this point I'm going to assume you're trolling

because I'm not that stupid.

goes to do something productive with his time rather than sit here and be trolled

gansub

nowadays installation packages have changed. many of them do not use configure

it is cmake now

no i am not trolling you

just sharing my viewpoint

it is when the build process fails finding help can be incredibly challenging

Videonauth

well guys , it was already a busy day for me, im going to relax a bit and watch some movies

gansub

as you say when you post a question people usually say just install the binaries

Videonauth

laters

gansub

ok @ThomasWard thanks for helping me with finding out the linux version. apologies if you felt that i was trolling you. i assure you i did not. just a fellow Linux/Ubuntu traveller

have a good weekend

Q: How do I enter a file or directory name containing spaces or special characters in the terminal?

dessert

I took the newline character out, that was too strange. :)

Videonauth

:P yes newline is strange and should be avoided at all costs

mabe you could mention that; +1 however never the less

dessert

The last codeblock totally confuses google prettify – yay!

Videonauth

9:58 PM

@dessert yep and i can tell you why :)

echo content >'\'  # print “content” into file “\”

dessert

@Videonauth obviously it thinks the backslash escapes the single quote – that's rather poor, isn't it?

Videonauth

google prettify see you here escaping a ' character

yep but never the less that are simple parsers which are by far not that evolved as the shell parser itself and so on

dessert

10:21 PM

@Videonauth Thanks for trying, but I don't think we can fix that, it's either removing the syntax highlighting for the whole last code block (I vote against that) or leaving it like that.

Videonauth

or escaping the escape caracter which would make the line wrong :P

'\\' would fix it

but i guess that would be wrong in this case

dessert

Yes, that would be a horrible workaround. :D
