@Seth @Oli --^

mods might have just forgot that it existed. Hopefully that will poke them again.

Q: Migration of tags (live-cd, livedvd)

5

This has already been mentioned here: 'livedvd' should be a synonym for 'live-cd' Correct term for 'LiveCD'? There hasn't been a change yet it seems. Do we really need live-cd, live-usb, livedvd, and live-environment? It seems that is a bit of overkill. I can understand there is some sort...

discussion tags

heh those are some pretty old meta posts

seriously though. anyone who didn't offensive that answer. please do.

should I create a new meta post?

5:46 AM

no i've tagged mods

they'll see it

@KazWolfe wow that celery post is still around

yeah. we need it nuked

i know everyone didn't offensive it.

has been 2 hours since i flagged it

which answer you're talking about?

-7

A: How to find firefox path?

You possess the mental capacity of a stick of celery. Maybe a Mac is more your style.

@Anwar ^

5:50 AM

oops!

why did you DV it

on my rude flag. it's deleted

A flag would have been enough

flag auto dv-ed it. I didn't

also damn i need to get to 20k soon

5:52 AM

I think flag + 20k user's deletion votes help

@edwinksl clean :)

so... how to i explode to 20k

you pace zanna

Journeyman Geek

You post many insightful and useful answers.

A guide of "How do you get 10k within 2 months" from her will be very much helpful :)

@JourneymanGeek that's boring

5:57 AM

@KazWolfe if only avogado video counted for rep

Nathan Osman

Uh-oh. My wildcard cert is expiring soon.

I either have to fork over $94 or switch dozens of subdomains to Let's Encrypt.

Not fun.

At all.

@KazWolfe you'll follow the tags you feel interested in and answer them.

i wish i got edit rep

vote on this tag synonym request if you agree askubuntu.com/tags/live-cd/synonyms

A: Cron is a spammer, how do I stop it?

1

Is the system running ouf of memmory? You can have a look in /var/log/syslog to see if you get any OOM (Out Of Memory) messages during the time of day when /etc/cron.daily/apt is running. /etc/cron.daily/apt is executed at 06:25, but there is a random sleep in the apt script, so it might be up ...

yay new user! :D

wait, people recommend tag synonyms?

6:03 AM

yes. after 2.5k i think

i thought we just get mods to deal with it, because it's more common sense than "i have the required number of votes"

@KazWolfe profile suggests this person is a pro

yeah, but still new user to site

off to a great start.

yeah dat sweet formatting for a first post

second actually

@KazWolfe fine. I don't see a way to delete synonym request. leaving it. I also thought everyone agreed on that ...

6:10 AM

@Anwar we do agree on it, but most of us can't vote because we don't have the required count.

and because often we don't, most people opt to yell at mods instead of use the voting feature, which is often heavily stinted by this issue.

Q: Not Found The requested URL was not found on this server

sometimes i wish i could comment with just "?"

maybe they... accidentally posted that question... somehow

you can, i think

same here

6:36 AM

maybe 15 question marks? :p

good idea!

Or 14 [spaces] and one ?

‮hello world!

starring that breaks the box lol

i think. it used to at least

i'm actually curious now. can someone star that to test it out? (you can ofc unstar it, i'm just curious)

6:41 AM

starred without a problem..!

not that one

it does break the box!

yay

is that an easter egg?

sorta.

‮nuf si edocinu

above this message is an empty message

hmm.. i starred the wrong one

it needs a better title I think. askubuntu.com/questions/824691/…

6:44 AM

@Seth Do the controls finally make sense?

@KazWolfe trippy

moo‮

‮hi @edwinksl

@Anwar I think that's the best title in theory, but the question is useless, that guy has a FUBAR .bashrc

I mean, a specific error message is a useful title for searching, generally

hmm...

but that one is no repro imo... interesting though

6:51 AM

@Zanna yeah he surely has some fancy things in his bashrc

mine is so boring

yeah but he keeps breaking it with that crazy stuff

it seems to be slurping the last command... dangerous idea...

Yay no hot water

awww that sucks

I need food, oxygen and hot showers

@Zanna sleep is conspicuously missing

Well. No propane means no hot water

6:56 AM

I also need sleep & electricity, but five items seems too demanding

7:07 AM

so if you want to do something to all hidden files in the current working directory, don't do this command-to-do .*

3

Bad Things Happen

did you see the person who did cd /etc/skel and then chmod 644 .* exotic way to FUBAR your system

I don't think you should star that... people might test hahaha

but no R right

so probably salvageable?

doesn't matter

I'm not sure... let me see if I can get out of a directory after removing execute permission on it

yeah I can get out

so should be fixable

yeah you could just cd / and chmod 755 /etc

and then fix /etc/skel

@Zanna write an answer? :p

7:19 AM

you think I should? I think they already gave up and got someone with physical access to boot in recovery

I am disinclined to test it hahaha

huh, TIL about apt-browse.org

seems pretty neat

ooh what's that?

A web browser for the contents of Debian (and Ubuntu) packages.

awesome

7:38 AM

answered it... I guess you upvoted haha

it's always you

:p

<333

7:52 AM

evening @andrew.46 :) (I think)

Evening @Zanna How goes it? Passed 30K yet?

hehe seems pretty slow this week, apart from Monday

but I'm well :)

how are things with you?

Mixed day I confess.....

There is a huge Yoga scandal that enveloped my Ashram and the report is out today

Horrible reading

@andrew.46

8:15 AM

@SeverusTux Not quite that cool :). I am a Satyananda Yoga teacher but I live with my family. My ashram is about 2 hours drive from me

what happened?!

oh, nice :)

@Zanna In the 80s there was abuse of young children in the ashram

omg

And it has been handled badly over the next couple of decades

8:24 AM

:(

8:52 AM

Hmmmm.... that is one way to quieten down a room...

the room is usually quietest at this time :p

Stefano Palazzo

High five @KazWolfe

9:07 AM

yay for fun questions!

heh saw them

& voted probably

LDJames is parsing ls though

unnecessarily

you should comment on it

and link to wooledge :p

I did in my answer

he is really touchy and I think he thinks I'm stupid

based on previous interactions

I don't wanna start that conversation

somebody here will eventually point it out haha

9:17 AM

I expect so

terdon will swoop in and fix it

Melebius' answer is nice

i don't remember seeing anyone use the prune option before heh

waltinator's answer to the other one does not work because of adding the path again in the reference

so that was something new at least for me

but I upvoted it because I just corrected it in my answer, probably I should edit instead

but I am shy about doing that

well then i suggest getting some liquid courage in the form of hot chocolate

9:20 AM

see how they have for dir in ~/path/to/*

and then ~/path/to/$dir

that makes /path/to//path/to/*

haha

probably just an oversight

definitely, very easy mistake to make

I am constantly forgetting what is actually in my variables

i expect someone to come along with a python/ruby/perl(!) script...

no doubt :)

nice to have a chance to use zgrep

it's time you write some snakey scripts

9:27 AM

for my test I got annoyed trying to find something that didn't produce too much output in real logs, so I just did ls -l /usr/bin > log1 and then gzipped it

I really really really need to learn python, I keep starting and getting distracted

and I zgrepped for python because python <33

morning @Arronical :D

Hiya @Zanna

@edwinksl I may be that someone!

how do?

this reminds me I should really delete some old logs...

Oreet cheers, had my daily dose of radiation in the form of a wrist x-ray. I really am starting to fall apart!

@Arronical howdy

aww what happened?

9:32 AM

@edwinksl o/

@Zanna Nothing recently, had an incident recovering luggage from a baggage carousel in March and had trouble with twisting motions in my wrist since then. It's a pain/weakness that I'm not used to, so the doctor suggested a precautionary x-ray

:(

a few years ago I fell on a slippery car park and hit my elbow, x-ray came up with jack, sent me home with nothing but advice to guzzle painkillers (not needed as it didn't really hurt unless touched, which hurt like bkafgafafkfjjaoiejrae) it is still not right to this day!

The thing is, by the time I got a doctors appt, it started feeling much better! Though I do land on it fairly regularly due to my whizzplanking habit.

whizzplanking eh?

ah actually I think they are right that their script is not parsing ls

it is not connected

for i in `find F1`
do
    ls $i
    if [[ ! -d $i/photo ]]; then
        mkdir $i/photo
    fi
done

separate references to i

doesn't use from the output of ls to do anything

still, I don't see the point of it

and backticks for command substitution are kind of deprecated

@Arronical my bad, sorry

9:51 AM

@Zanna Elbows do often develop those little gritty things which feel like bits of random bone fragment, but are more likely to be weird protective cartilage things.

@Zanna Also breaks horribly for any slightly strange file name. Even spaces will break it.

@terdon yes, didn't quote the variables!

@Zanna Yeah it's nice to live in a time where being a bit older and skateboarding is a bit more acceptable.

And there's no point in checking fo a dir named photo. Just create it. Use mkdir -p if you don't want to see any errors for an existing dir. And, in any case, that's just checking for a directory of that name, what if it's a file instead?

@Zanna No worries, I don't mind admitting when I'm wrong.

9:53 AM

@Zanna Not only. It's broken as soon as you use for to iterate over the results of find:

$ touch 'a file with spaces'
$ for i in $(find); do echo $i; done
.
./a
file
with
spaces

hahahaha

While is always better (though still breaks on newlines here):

Is anyone going to comment to this effect?

$ find | while read i; do echo $i; done
.
./a file with spaces

@Arronical it doesn't feel weird, only hurts like hell when I hit a certain spot

9:55 AM

@Arronical heh, that is an extremely rare quality in SE. plenty in SE will argue 24/7 :p

@edwinksl I'm wrong often enough that I wouldn't have time to eat if I took that stance. Hold on... there's a novel weight control concept, maybe I can write the new diet fad book!

3

@Arronical lmao

@Arronical Heh, and then we'd all starve :)

Although, if you could manage to sell it to politicians, that would solve a few problems.

2

@terdon But who would facilitate filtering most of the wealth to the mega rich? Sorry political views leaking into SE chat!

@Arronical totally agree with that view

10:15 AM

We couldn't be prouder of our community, and what they do every day to help all the Joshes (and Janets) out there. https://t.co/pNH3hJcxV8

heh that's awesome and so true

@terdon @Zanna Also, what helps is null separator

-print0 | xargs --null

@Serg Oh really? :P

yup. while read also can do it. . . .but it is bash specific. find and xargs are non-shell specific

10:19 AM

@jokerdino vaguely relatedly, I got a letter from my mum yesterday that made me happy... I thought she was annoyed with me for being absorbed in AU, but in her letter she says "it's so good that you are spending time helping people..."

Kindness is massively undervalued in this world. It also tends to have the side-effect of being beneficial to ones own happiness.

5

@Zanna Thanks mum!

@jokerdino ikr ^_^

@Zanna I thought you were very kind in the chat yesterday, just as I was thinking 'there's a handy Stack Exchange site for asking questions about Ubuntu'!

lol I think their post would have been closed as dupe instantly

that was nothing special, @Serg spends ages helping people in here

if someone asks for help with something interesting or difficult, I tell them to Ask A Question instead because it will help other ppl

10:27 AM

Are we really helping people? is my thought sometimes...

btw. a dupe askubuntu.com/q/824759/61218

Being nice and kind is actually draining on you.

hmm... that's also possible

missed a flag

I think... it depends... I think being nice and kind gives me energy when people are nice and kind back, but otherwise it's very tiring, like carrying a heavy weight

@Anwar i hope to believe so

@Anwar it's hard to keep going with that doubt...

10:32 AM

You give your positive energy when you are nice to others. You get some when others are nice to you.

@Serg me too!

@Zanna truth be told, i spend way too much time on AU, sometimes at cost of my own tasks

@jokerdino true

@Serg me too

Otherwise, it's one-way traffic and I won't be able to be nice for longer periods.

@jokerdino true and true

10:34 AM

you must have good batteries though

welp, i guess i ain't sleeping . . . I must be on campus for lab by 8 and it's 4:35. Hour and 15 mins to get there, 30 - 45 mins to wake up. That leaves nothing for sleep

what have you been doing?

looks for answers by @Serg

Honestly, YouTube. Then @ 3:45 my gf send me message, so we were chatting a bit

timezone troubles

@Zanna ...well... I was being skeptical. It's true I'm (and we're) helping. but we're being recognized for that. being reputed... so, not without any benefit on our side

btw. more and more questions are being asked as a dupe of this one

10:41 AM

Honestly, it's a fallout effect from Monday. Remember i stayed up then to do homework ? Monday was basically pain, just had to go through the day. Then slept all Tuesday basically. Wednesday now, didn't feel like tired till 2 am. It all piles on

ha ha.

Sandro

how can i get overall CPU utilization percentage

in ubuntu

@Anwar yes but I think that's a separate thing, and a good thing... I'm not such an amazing person that I can go on trying to be helpful with no acknowledgement... if you help people offline (I don't like the appellation "irl") you get kisses and hugs, here you get accepts and upvotes instead (and other cool things) (and obviously it improves the site & users in various ways to measure people's contribution somehow...)

Sandro

i see percentage for ever cpu in system monitor

now i want to know overal cpu percentage

hmm I think top only shows the overall percentage?

hehe I should give my system something to do

%Cpu(s): 1.2 us, 0.2 sy, 0.0 ni, 98.5 id

what's that python monitoring program that does a nicer job? I forget the name... or am I muddled?

10:50 AM

that also true

my brother just pinged me saying: I am installing Ubuntu

@Zanna It can show both. You toggle it with I (that's shift+i)

@Sandro just open a terminal and run top

@terdon neat :) thanks for educating!

@Sandro while true ; do ps -e -o cmd,%C | awk '{a+=$NF}END{print a}' ; sleep 1; done

you can even remove the cmd part , just leave %C

askubuntu.com/questions/824738/… don't know why this happening. I even tried chmod -w on defaults.list and mimeapps.list. but it works!

10:54 AM

And you could use watch to stop it from scrolling all the time:

watch "ps -e -o %C | awk '{a+=\$NF}END{print a}'"

@Serg how come now I'm getting 5.8 whereas top was showing me ~1%?

^ that too

@Zanna because they're probably calculating different things. Plus top is showing several sections for cpu %

@Zanna 'Cause you were probably only looking at the 1st number, you need the sum

%Cpu(s):  6.0 us,  3.0 sy,  0.0 ni, 88.8 id,  2.2 wa,  0.0 hi,  0.0 si,  0.0 st

You want us + sy + ni

@terdon that gives me ~25

10:56 AM

@terdon I know, but I was just subtracting idle from 100

Also, the number changes many, many times

@terdon of course... but I still don't see the reason for huge difference

@Zanna Oh. That makes more sense, I guess.

But there's something about how the percentages are calculated. I think I've written it up somewhere

:)
