The farthest I can get this screen mirror is to the splash screen for it on the TV and a "Connecting" message on the computer

I'm not getting an IP on its private network

Serg

Very odd, I can colorize output of awk using escape sequences in the BEGIN statement, but not otherwise

Zacharee1

I can get Looney Tunes for free on the Roku

Rinzwind

14:42

besides my comment fine :+

@TheBrownOne gatz :+) now give them to me.

Zacharee1

@Rinzwind someone's jealous

:p

Rinzwind

nope/

Zacharee1

I just gave them what they need to use to decide

Rinzwind

my 1st action was to closed it ;-) it is a matter of opinion

Serg

So a group of random kids just were walking though hallway and looked inside the lab . . . .And I was greeted by a panda (a kid in panda hat/mask )

Zacharee1

14:43

But it isn't' they're all equally easy :p

Rinzwind

not always true

I have seen beta to normal go wrong due to a small bug

(and the bug killed the video driver so was pretty damaging)

@Serg noooooooow the question of the day. DID THE PANDA LOOK PARANOID?

Serg

@Rinzwind This one was quite cheerful actually :)

Rinzwind

oh he found a bamboo stash?

Serg

Maybe :) After all it was just a little kid , and kids are mostly cheerful.

user136984

@Serg They have to, it's part of their training (as a Panda spy)... In fact it was one of my little evil minions come to plant bamboo in your lab! >;D

Zacharee1

@ParanoidPanda you trained them well , I see :)

Zacharee1

@ParanoidPanda still stuck ? ... offline again ? :D

Serg

Maybe I should go watch some tv series or something . . . I don't have that much motivation right now.

cl-netbox

@Serg why not ... good idea ... sometimes it's not the right time for something else ... :)

cl-netbox

@A.B. Hello my friend ! :) How are you ? :)

A.B.

@cl-netbox headache

cl-netbox

@A.B. oh ... not very nice ... from the weather ?

A.B.

@cl-netbox I don't know, was a hard week

cl-netbox

@A.B. so from work ... a little bit better now ? :)

Serg

@A.B. sorry to hear that , my friend, hope you feel better eventually. Try massaging point between thumb and first finger, maybe that will help

A.B.

16:36

@Serg thx =)

GitLab-CI and the GitLab runner drives me crazy

Serg

what's gitlab ?

A.B.

@Serg about.gitlab.com

Serg

@_@ that seems interesting . . .

Seth

why is that confusing?

Serg

@Seth well . . i am a bit confused, but that's not what i wanted to express with that emoticon

Seth

16:46

oh. pretty sure that's the confused emoticon.

cl-netbox

Hi @Seth ! :)

Seth

hi!

Serg

According to internetslang it means dazed or hypnotized . . . i'm sort of interested . . .

Q: How to install Electrum 2.6.3 bitcoin wallet on Ubuntu / Mint and derivates

Today's question of mine was How do I install Electrum 2.6.3 bitcoin wallet on my Linux Mint, Ubuntu and it should work on other derivates.

user139252

17:11

I realise now how sad that sounded, @Seth can delete it

Seth

was that asking for it to be deleted or giving permission? Now I'm not sure..

user139252

Asking for a delete, I'll leave now

Serg

ugh . . . I'm trying to print a list of items from an array, but i don't want comma after the last item . . . it's annoyingly simple yet i can't approach it

Serg

17:28

My script works ! \ (^_^) /

now I can make the active window float up to the top of the launcher

@Serg I didn't there was a comma after the last item...

Serg

@TheBrownOne there isn't comma after the last item. I am using for loop in bash to printf "%s , " each item

user139252

Gotta run

Serg

See ya !

Seth

it's crazy how awesome coreutils and bash are..

Serg

17:55

@Seth they sure are . . . there's tools for a lot of tasks : tac, basename, bc, etc.

Of course python combines a lot of those in itself . . . but still pretty awesome stuff can be done with coreutils and bash alone

Seth

the important part is knowing when to use what tool.

Serg

that true . . . a good example of that was couple days ago, when a user was trying to find external disk usage by ls'ing recursively all the files and summing their size . . . which is what du already can do anyway :)

So as of right now my git has 19 scripts . . . Of course quality is better than quality but still, makes me quite happy for some reason

badp

18:10

@Seth if only bash didn't have such a foul syntax

Serg

@badp what's wrong with bash syntax ?

badp

almost all of it :P

Serg

That's very descriptive

badp

fish has a much nicer syntax, but it does lead to you googling how to do some stuff that bash has special syntax for

Seth

@badp eh, you get used to it.

I'm so used to it that when I tried fish I absolutely couldn't do anything :P

and fish doesn't have !!.

or &&

Now I use fizsh.

badp

18:13

&& is replaced by and (git pull; and git push)

I forget what !! is supposed to be

Seth

@badp yeah but it never worked for me..

the syntax was weird.

@badp expands to the last run command.

badp

then that's replaced by the up arrow and the Enter key? :)

Seth

no no, it's for use in expressions.

Serg

Meh, bash isn't the worst. My concerns are more with technical stuff , like there's a lot of small issues that aren't apparent right away, for instance newlines in filenames, the number of arguments limit in exec and so on and so forth

Seth

the most used of which is probably sudo !!.

badp

18:16

@Seth ehhhh, that would become a misfeature with fish's always-on ctrl-r

Seth

@Serg which goes back to my earlier point, if you start running into a lot of those you're probably using the wrong tool.

badp

if you really want that you can sudo (history | tail -n1) (fish history doesn't put numbers in the output)

Serg

@Seth I don't run into those that much on daily basis . . . but over the course of using Ubuntu for 2 years, I've come to see some of these issues . Some of the questions on this site were quite eye-opening .

It's just that some things are not apparent right away. Like , when I realized my variables disappear if I set them over a pipe, I didn't know pipes are actually subshells

Seth

@badp that's like 10 times the characters :P

@badp what's that supposed to do? ctrl+r has no apparent affect for me in fish..

badp

@Seth actually it's the same number of keystrokes

after the first time

sudo (→

...I think

yeah

@Seth it searches through your command history

gfycat.com/VapidConcreteFowl

Seth

18:29

@badp but then if I use another subshell it won't default to the history one.. Although I guess I can just keep pressing →?

19:15

@j0h @Rinzwind care for a testdrive? ppa is available: Xenial, Wily, Vivid, and Trusty (at this very moment, Xenial is pending): ppa:vlijm/abouttime

Serg

@JacobVlijm if I may suggest so, pm and am typically go after the time , so like quater past six | pm | evening , at least to me, would look more appropriate

Jacob Vlijm

@Serg good idea! will change the order. Probably some more small changes will be in the next few days :)

A.B.

@JacobVlijm Doesn't work with GNOME 3

Jacob Vlijm

@A.B. What are the symptoms? Will test in on Gnome...

A.B.

@JacobVlijm I can't see the time, only the icon

no screenshot possible :(

Jacob Vlijm

19:24

@A.B. I assumje setting prefs does not change it? in Mate, I had to enable indicators.

A.B.

In GNOME we have this taskbar overlay

at the bottom left corner

Serg

quite possible it's one of those things that works in unity alright but not in gnome :/

A.B.

yes

Jacob Vlijm

@Serg I tested it on Mate.. Starting up Gnome

Serg

user139252

19:30

@Zacharee1 @Fabby your sites might go down later this week, I'm doing what I can to prevent anything from happening

Zacharee1

@TheBrownOne OK. Why though?

A.B.

@Serg I was to slow =)

Serg

@A.B. the chirp question ?

A.B.

@Serg yes =)

Serg

@A.B. It's alright ;) there's plenty of other ones

A.B.

19:32

=)

Jacob Vlijm

@A.B. nope, doesn't work on Gnome (yet) it seems also Gnome misses some dependencies which are default on Unity.

A.B.

@JacobVlijm the output works. I can hear the voice

Jacob Vlijm

@A.B Thanks, this was the case on mate before I set support for indicators on, on Mate 15.10. Wait, what is your Ubuntu version? Mate is supported from 15.10

A.B.

16.04 and GNOME 3.20 =)

A.B.

19:53

@Serg, the awk guy =)

1

A: How do I highlight a word or a phrase in a command's output?

Using ANSI escape sequences , one can colorize anything in console. Combining that method with awk, we can filter specific words , and make them colorized. Consider this example: $> df | awk '{for(i=1;i<=NF;i++){ if($i~/sda/) $i=sprintf("\033[0;36m %s \033[0;00m",$i)}; print}'

Serg

Yeah :) one of my favourite tools

is?

Maybe I should publish some of my other scripts

SQuirel

I merged 2 accounts and my rep went from 75 to 95

A.B.

@Serg sure!!!

SQuirel

20:09

but I got banned from asking questions :(

Serg

@A.B. they're quite simple though :/ I've a script that keeps changing the colors of the unity launcher

A.B.

@SQuirel currently 106 =)

SQuirel

106 is combined from all sites

A.B.

@Serg GitHub or GitLab?

SQuirel

I could ask question on both accounts before the merge

Serg

20:10

@A.B. I've got them all on github. What I mean is publish them here , on AU

SQuirel

but I can't after merging :(

A.B.

@Serg ok, understand =)

SQuirel

I don't think I've asked/answered a question in months!

stack exchange really needs to lighten up...

A.B.

@SQuirel Ask a mod

Serg

@SQuirel yeah, I rarely ask questions myself. You probably should learn from @ParanoidPanda I've no idea how he comes up with all those questions O_o

A.B.

20:12

@Serg LOL

SQuirel

How many questions have been asked on stack exchange?

Serg

@SQuirel in total ? um . . . probably over a million

SQuirel

ok then, so there's over a million question all on the same topic

A.B.

ParanoidPanda has more than 400 questions? @_@

SQuirel

there's a pretty high chance that my problem is somewhat similar to someone elses problem

why should I be punished for a "duplicate"?

yeah, i've looked and there's only badges for amount of views and score on a question

there's no badge for amount of questions asked

Hi guys

Abhishek Bhatia

Reading this answer stackoverflow.com/a/1516177/3646408

If the line is empty, then read() returns with zero, and that is interpreted as "end of file"

hbdgaf

@Serg Blogged a thing for some company about deploying w3af-gui on OSX based on a bug report thread from the mailing list. It was a workaround deployment in docker instead of fixing the bug though. The bug was the fault of Gtk2/X11 borderless window bug in Quartz. Don't have to fix the bug necessarily.

Abhishek Bhatia

21:21

Why doesn't it exit when I enter nothing and press enter?

As stated in the answer the line is empty.

Serg

@AbhishekBhatia because it's not the correct answer

cat should exit not because there's nothing on the line , but because stdin closed

user139252

@Zacharee1 @Fabby all is okay, don't worry about your sites. I'm getting things handled.

Serg

That happens when read command inside the program fails to read something new

Ctrl + D sends a special escape sequence that closes the stdin, so read command inside progam will fail to read more stuff

therefore cat will exit

And technically, when you hit enter, the program still receives a newline character

\n

so line is not really empty

Zacharee1

@TheBrownOne kk what was happening?

user136984

Long day...

user136984

Goodnight! :)

Zacharee1

@ParanoidPanda @Fabby's not here, so 'Pumpkin!'

All the logs for X server are in /var/log/ folder, named /var/log/Xorg.n.log , where n could be number form 0 to whatever. There is also /var/log/lightdm/ folder . You can look through there @aman207

@Seth I haven't answered or asked a question since February 26. And the answer I gave last was up voted twice. Both of my accounts were able to ask questions before the merge. But after I merged them I'm not able to ask questions any more.

Seth

23:34

@SQuirel There's nothing I can do, the system is entirely automated. You need to improve existing questions or provide some more good answers..

SQuirel

23:46

@Seth How many questions are on askubuntu.com?

Seth

@SQuirel over 200,000.

SQuirel

Well considering there's over 200,000 questions about the same topic there's going to be some similar questions...

Why should a user be punished for "duplicate" questions?

badp

because we have accidentally bought so much tar and feather, we literally don't know what to do with them

Seth

@SQuirel because you are wasting people's time. You make them do the searching for you. A duplicate here and there isn't a big deal (I have them too), but if you are being blocked by the system then you have more than "a few".

you have 2 duplicates, 1 closed question and ~8 deleted questions.

SQuirel

First off I only started using ubuntu in November 2014

The questions were legit newbie questions...

I could ask questions on both accounts before I merged them

Seth

23:56

it has nothing to do with how much you know about ubuntu, and everything to do with how much time you are willing to put into asking good questions.

For example:

Q: Record a linux terminal

is it possible to record a linux terminal and save it as an mp4? I've tried using a few screen recorders, but they save in bad quality or take up too much system resources... This in NOT duplicate of How to record the terminal on a server? None of those programs will let you save as a video f...

command-line

SQuirel

Yes and i've never been able to record a linux terminal yet!

So I gave up

I wanted to save it as an mp4...

not a gif or some weird unusable format...

Seth

Now that's probably not a duplicate, but if I reopened it I would probably end up closing it as unclear or at least downvoting. You want to "record a terminal to an MP4", okay that's relatively clear.. But then you say "the things I've tried either have bad quality or take up too many resources", but you don't tell us what you've tried, anything about your quality cutoff, what you consider "too many resources" or anything.

SQuirel

And the duplicate answer was from 3 years ago...

Seth

All we can do is slap random guesses on the post and hope something happens to meet your unwritten requirements.

I've tried all the screen recorders I could find
