@Zanna as long as it is gone :)

Edity

good morning chat

Zanna

21:15

@JacobVlijm hah any time :D

user136984

As I don't order things like this very often if at all, I have no idea from where to get a bullet proof vest which I'm sure actually bullet proof. Does anybody know a good and trustworthy provider for such clothing?

Zanna

@Edity morning :)

WinEunuuchs2Unix

Good afternoon Edity

user136984

Since the attack in London, I have decided to just get a little more paranoid.

Edity

;-;

WinEunuuchs2Unix

21:16

The odds are better of dying in a traffic accident @ParanoidPanda better stay indoors using your logic.

user136984

@WinEunuuchs2Unix: Maybe, but I would still like to get some sort of body armour.

user136984

If something happens, it probably won't be much use anyway, but I would just like to have something.

Edity

sudo apt-get install memorium

user136984

So I assume that the answer is nobody knows?

user136984

If so, I will have to see if I can find some more paranoid people... :D

WinEunuuchs2Unix

21:18

Umm... a pocket-full of rocks to throw at would be terrorists with knives like London had?

user136984

Well, I've got a steal sword, but I probably won't be happening to carry that with me when something happens.

Zanna

@WinEunuuchs2Unix or getting struck by lightning

WinEunuuchs2Unix

An inflatable car crash bag to set-off if would be terrorist tried to run you down in a crowd? Really trying to prepare for such things is futile. That said whenever I cross street I'm mentally prepared and ready to react for a car to hit me... jump and roll over the hood (bonet in Zanna speak)

@Zanna lightning isn't always fatal... who knows might be free 1950's style electro-shock treatment from higher power :p

Zanna

:/

user136984

Well, if I could find some military-grade full body armour I would feel a little safer...

WinEunuuchs2Unix

21:22

They sell kevlar clothing and knife-cut resistant gloves shrugs

Edity

windows is spamming me with cheesy stuff

user136984

@Edity: Just get some crackers and you can have a nice snack! ;P

WinEunuuchs2Unix

You should ditch windows.... try this thing called "Ubuntu"... I've heard people like it :)

Edity

i'm eating crackers tho

user136984

@WinEunuuchs2Unix: Yes, I guess that there will be something somewhere out there.

Edity

21:23

@WinEunuuchs2Unix VMware edition

WinEunuuchs2Unix

I'll be using Windows 8.1 soon and running Ubuntu and this chatroom in a virtual box.

user136984

@Edity: Then you're all set to go Wallace! ;P

Edity

"how likely are you to recommend Cortana to another friend?" me: NAH DON'T USE CORTANA USE SIRI

"your microsoft account needs attention to get insider previews"

me: NAAH, IF IT'S BROKEN DON'T FIX IT

crickets chirping

user136984

I wish the Arch GNOME maintainers would hurry up with shipping in 3.24.

WinEunuuchs2Unix

What features are you looking forward to in new Gnome?

user136984

21:29

The Night Time mode.

user136984

That would be really useful to me.

user136984

Or whatever it's called.

user136984

There is also a bug I found today in my 3.22 installation which I would like to report.

user136984

However I can't do that until I've tested it against 2.24 which I don't have.

user136984

I'm not sure, but I think that it's probably Arch specific.

user136984

21:31

So I can't just test it on another distro.

Zanna

WinEunuuchs2Unix

@ParanoidPanda I just posted a similar answer to night time mode last week: askubuntu.com/questions/894460/… Gnome calls their new feature Night Light

Night Light and similar packages work by adjusting color balance... adding more red at night. Mine works by reducing display brightness before sunset and increasing display brightness after sunrise.

Bonus it tells you when sunrise and sunset is :p

user136984

22:32

@WinEunuuchs2Unix: I find it hard to sleep at night because I'm using my machine so close to that time.

user136984

So I think that this feature might just be my saviour.

user136984

I think it's probably the really bright colours that do it.

user136984

I should probably also just try not using it up until such a late time, but that's difficult because I have lots of work to do and not much time in the day to get it done so now is really the only time for me.

user136984

Anyway...

user136984

Goodnight folks! :)

Android Dev

23:01

Can we dupe this? askubuntu.com/q/896529/518562

Byte Commander

maybe better merge than dupe?

Android Dev

@ByteCommander shrug They're essentially the same thing. I'll let the more experienced users decide what to do with it :)

WinEunuuchs2Unix

@AndroidDev You're more experienced than me! Certainly entitled to comment freely.

Ohhh I see Byte answered that question nominated as dupe... makes sense now :)

Zacharee1

23:29

@ByteCommander so I can direct both stderr and stdout to a file, but is there a way to prepend everything from stderr with, say, "E:"?

Byte Commander

sed

let me compose something...

Zacharee1

OK

this is what it is right now btw >> /data/media/0/Zacharee1Mods/output.log 2>&1

Byte Commander

(btw let me advertise my answer about this here, which only needs 5 more votes for score 100 askubuntu.com/a/731237/367990)

Zacharee1

whoa

that's a nicely formatted table

edwinksl

downvoted

Zacharee1

23:34

muahahahahahahahaha

envy strikes again

envywinksl

Byte Commander

Does it need to be the same logfile?

edwinksl

oh but look whose dp is green

Byte Commander

@Zacharee1 The line order will be hard to preserve. Is it bad if error lines might be delayed?

Zacharee1

@ByteCommander it'd be nice

hmm

@edwinksl hue

@ByteCommander is it possible to just prepend stdout with "I:" or something as well?

so then everything stays the same?

Byte Commander

( lsb_release -a 2> >(sed 's/^/E: /') > >(sed 's/^/I: /') ) | tee both.out

Zacharee1

23:40

whew

Byte Commander

This is asynchronous though, as it uses two different process substitution subshells

basketball

Hello

Byte Commander

so it can not guarantee on correct ordering

Zacharee1

no way to make it synchronous?

basketball

Can someone please help me with my problem...askubuntu.com/questions/896901/…

Byte Commander

23:41

I don't know, that would require my tool to know from which stream a line comes when it receives it...

basketball

@ByteCommander

Byte Commander

But I only have one stdin

Zacharee1

@ByteCommander I guess I'll just settle for not having them then

Byte Commander

You may of course ask a question on the front page or on U&L

Zacharee1

true

Byte Commander

23:42

Maybe someone can find a more magically looking way

Zacharee1

but it's not technically Ubuntu :p

and would it belong on U&L?

Byte Commander

why not?

Zacharee1

idk

Byte Commander

there you get the best shell gurus

if you manage to attract their attention

Zacharee1

heheheheh

HALP MEH WIT DIS PROBLUM PLSSSSSS

Byte Commander

23:43

but I think it's an interesting question, so your chances are probably not too bad

ask Serg too

Zacharee1

I'll ask after I get this button listener working

it's just this one that has no effect when I press the button

it's weird

Byte Commander

and share me the link when you posted it

Zacharee1

oui monsieur

Byte Commander

tres bien

@basketball sorry, I don't know

Zacharee1

guh

Byte Commander

23:46

@Zacharee1 Actually, first result on DDG:

Q: How to capture ordered STDOUT/STDERR and add timestamp/prefixes?

I have explored almost all available similar questions, to no avail. Let me describe the problem in detail: I run some unattended scripts and these can produce standard output and standard error lines, I want to capture them in their precise order as displayed by a terminal emulator and then ad...

That answer though... o.O much magic!

#!/bin/bash
exec 3>&1
coproc SEDo ( sed "s/^/STDOUT: /" >&3 )
exec 4>&2-
coproc SEDe ( sed "s/^/STDERR: /" >&4 )
eval $@ 2>&${SEDe[1]} 1>&${SEDo[1]}
eval exec "${SEDo[1]}>&-"
eval exec "${SEDe[1]}>&-"

Zacharee1

I have no idea how to adapt that lol

Byte Commander

lol

> Note several things:

It is a magic incantation for many people (including me) - for a reason (see the linked answer below).

Another alternative using fifos:

    # Create FIFOs for the command's stdout and stderr.
    stdout=$(mktemp -u)
    stderr=$(mktemp -u)
    mkfifo "$stdout" "$stderr"

    # Delete the FIFOs when this iteration of the loop finishes. Use `trap' to ensure
    # cleanup happens whether we finish normally or are signalled.
    trap 'rm -f "$stdout" "$stderr"' EXIT

    # Read from the FIFOs in the background, adding the desired prefixes.
    prefix 'O:' < "$stdout" >&1 &
    prefix 'E:' < "$stderr" >&2 &

    # Now execute the command, sending its stdout and stderr to the FIFOs.
