it's summer
tryouts are in the beginning of next year
 
isn't summer vacation ending soon?
 
yep
 
so then ask your teacher when school starts. it is not reasonable to expect us to know what is needed to get on your school's science olympiad team.
 
i was hoping some science olympiad team coaches would know
so i could know before hand
the tests should be quite uniform for qualified school teams, because they look for the same things
 
12:03 AM
i am not trying to be mean, so don't take it the wrong way, but does it look like we have olympiad team coaches here?
 
no, i'm sorry for asking here
i didn't know ubuntu was a OS
 
now i am not sure where you should ask your question, but this is definitely the wrong place
 
as stupid as it sounds i thought it was some random name and this was a chat where u can ask any thing
i guess not
so see you
 
good luck
Please if you can guide me to meet you — lyly 7 mins ago
@ByteCommander OP wants to meet you :/
 
IM DEAD XD
How do you like quote those?
 
12:08 AM
just copy and paste the link
 
link?
wont that just link the q?
 
the time stamp itself is a URL to the comment
 
what are you trying to link to? a comment?
 
12:11 AM

for me to understand I am a compartaive study between hadoop is spark and i did not do it that installed java8 and hadoop me my spot only installed spark so I know how my teacher has installed java8 and I not master really I know what to do — lyly 13 mins ago
there we go
 
there
 
@edwinksl replied. If he still does not manage to come up with the requested output, he should sell his computer and make sure not to reproduce...
 
@ByteCommander awesome, let's hope OP can calm down and provide actionable information
 
I just found this again XDD

Q: networking.service refuses to start on boot (failed to bring up lo, file exists)

Byte CommanderSince I attempted to set up an encrypted swap partition (Encrypted swap partition does not show up in /dev/mapper), I get an error during boot that the networking.service could not be started. Here's the info I get when running the command described in the error message: $ systemctl status netw...

@Serg Can it be that your powerflow indicator is spamming my /var/log/syslog ?
I have huge sections in there looking like this:

1:52 AM
is 80 rep possible in 3 hours?
 
you posted on a pretty popular question. i would say yes
 
well, let's go then!
 
if you can answer byte's question, you will probably get 75
50 bounty + 25 accept+upvote
 
Yup, that would be nice :)
 
commented
 
1:55 AM
and i would throw in another upvote to make it 85
 
^~^
 
The other one about cryptswap is also still open and will be bountied as soon as the lo network interface is fine again.
@KazWolfe this:
$ cat /etc/network/interfaces
# interfaces(5) file used by ifup(8) and ifdown(8)
iface lo inet static
   address 127.0.0.1
   netmask 255.0.0.0
 
just to humor me... get rid of address/netmask?
or better yet...
replace anything of lo with:
auto lo
iface lo inet loopback
 
Hmm...
I wonder how those settings got there...
trying.
 
posted, i'll withdraw it if i'm being an idiot.
did i brick byte's computer?
 
2:07 AM
lmao
 
put that on my resume.
 
he ded
 
Let's not pull a Terdon here.
 
@NathanOsman /r/OutOfTheLoop
i think i just did actually break his networking
:'(
 
@KazWolfe nope, it's fine :)
Just wanted to reboot twice to make sure
 
2:12 AM
It's an interesting story :D
 
Ouch.
 
oh lord terdon
 
Yeah.
From that point on, we adopted the phrase "pulling a Terdon" to refer to irreversible loss of data.
:)
 
And I tried to enable cryptswap again before the 2nd reboot to see if it conflicts... It did not, but cryptswap is still broken and needed 1:30 min to time out.
 
oh my god.
rm -rf /etc/askubuntu/users/terdon
 
2:16 AM
To be fair, it was a lesson we all learned that day.
 
@KazWolfe Accepted and upgoated, but the bounty needs another 22 hours before it's ripe enough to get harvested...
 
@KazWolfe so close to 10k
 
@ByteCommander commented on your other problem
 
I saw. And no, I did not mkswap afterwards, that was never mentioned anywhere. It looked like the crypttab setting should take care of that. @KazWolfe
 
well, try it lol :D
and you'd think that but this is linux
 
2:17 AM
mkswap on /dev/sda4?
 
i'm pretty sure that it needs to be mkswap'd.
if that's the one where the swap is
verify just to be sure
oh nevermind i am stupid
swap does run the mkswap command
 
But if I mkswap the partition, that would be meaningless because it should get overwritten with the encrypted swap partition file system...
 
but try it anyways.
shrug
Someone else said it works

A: 14.10 - Swap not available

SommopfleI traced /dev/mapper/cryptswap1 down to /dev/dm-1 so this worked for me: sudo mkswap /dev/dm-1 sudo swapon -a This enabled the swap that was already there. I am using Ubuntu 14.10 64-bit.

also i'm assuming you're not using LUKS?
 
But that only worked because there was already an encrypted drive. I have nothing in my /dev/mapper except a "control" device.
 
i see that.
just a wild guess really on my part
 
2:21 AM
And about LUKS... No idea, I use what I described in my question... Dunno what exactly that is behind the scenes.
 
you may need to specify a cipher
but yeah do try mkswap
and add ,cipher=aes-cbc-essiv:sha256 after the swap command in crypttab
i wish i still had my encrypted box to look at.

swapon -a?
 
Swap on, Swap off, The Swapper
 
I can't swapon as long as the encrypted device is not there.
 
2:25 AM
oh, right.
update-initramfs -u and reboot maybe?
i'm not sure where the crypttab is parsed in the boot order
 
What has initramfs to do with that?

Q: 14.10 - Swap not available

meta221My swap doesn't seem to be working. I tried to fix it but nothing I tried worked. Here is some relevant information to troubleshoot the problem: During install I chose to encrypt my home folder. Seems cryptswap is being used. When I open the gnome-system-monitor it says "Swap is not available". H...

answer to this question, just going with it
Guessing in Linux is okay as long as you never type rm!
 
let's try adding the cipher first...
 
or that :D
 
no change yet.
now initramfs
 
2:29 AM

Did I screw it up?
 
i think you want cryptdisks restart

Argh!
Your mkswap changed sda4's UUID!
 
yes?
oh. lol ^^
forgot it did that

it couldn't grab auth for some reason
 
@ByteCommander From CLI?
Unity / Gnome use a D-Bus daemon IIRC that brokers this on behalf of the user.

Circuit boards weren't invented soon enough.
 
2:48 AM
@NathanOsman Yes it does.
 
@ByteCommander interesting.
 
@KazWolfe Did not survive the reboot, it timed out 1:30min again and the /dev/mapper is empty.

ohhhhhh.
cryptswap gives it a new uuid each time
 
Let's see what gparted thinks of that...
 
try hard-referencing it? (/dev/sda4 intead of uuid?)
 
2:53 AM
But all the docs and tutorials do it with UUIDs!
And they claim using /dev/sdXY is unsafe because if it changes, data partitions might get overwritten.
 
true.
gimme a sec to make dinner and i'll think
or install one on a vm or something
 
Take all the time you need, 5AM is late enough for me to go to bed finally...

@Zanna i am surprised someone actually wants to disable colors. they are pretty damn useful
 
I'm lost without ls colors
 
same
 
@KazWolfe 10K is kinda the point where being a high rep user gets fun ;p
 
the first thing I do in my empty .bashrc is add alias ls='ls --color=auto'
 
did you add an alias for ll?
i think i use ll more often than other variants of ls
 
6:56 AM
maybe they have some kind of sight disorder though and the colours just make it hard to see for them
I never use ll
I don't find the file type symbols useful
 
[ SmokeDetector | MS ] URL-only title, bad keyword in title, pattern-matching website in title: nutrahealthtrimsite.com/t-volve/ by jopyzmahix on askubuntu.com
 
I add one for my favourite switches
alias lm='ls -lAtr'
 
ls -Al?
ah close, 50% right
 
and one for hidden files & directories
alias l.='ls -d .*'
well the tr are just for obsessive people right? hehe
 
i can't recall the last time i wanted/needed to use -t hmm
 
6:59 AM
I find it useful sometimes :)
hahaha I've just seen "can't install Kumbuntu" XD
 
i like colors so much i made a git alias for diff --color-words :P
 
that's a good one!
 
it is very useful because i have no restrictions on number of characters per line in my latex files
so i need to do word diff with colors
 
very cool :)
 
think i gonna get some hate from 80-char-for-everything people :)
 
7:03 AM
OP saying they commented the aliases and they still have colour o.0
pfff
I find that part in .bashrc about "uncomment for colored prompt..." hilariously sanctimonious
 
@Zanna Actually I know nothing (compared to Gurus). Need to learn a lot
good morning people
 
"uncomment for a colored prompt if you are a mere child toying with the command line"
morning || afternoon || evening
meh, modesty @Anwar but the more you learn the more it seems like there is still
 
Haha, the simple stuff is what always gets me. Good now! Thanks! — Kyle Drummond 15 secs ago
 
hahahaha "exit terminal and start it again"
"oh thanks, that got it"
how to format quote? I still cannot do
 
just sourcing wouldn't work?
 
7:07 AM
@Zanna just copy the link and paste it here
 
sourcing has to work
must have mistyped it
when I copy the link and pasted it before, didn't work
if you want it for just 1 command put a \ in front of the command ;-) (\ls -l will drop the colors too for that 1 time). — Rinzwind 11 mins ago
aha
 
^ it works
needs time
 
^_^ thanks
 
you're welcome :)
 
haha he accepted your answer even though force_color_prompt was already commented @Anwar
 
7:10 AM
@JourneymanGeek Oh?
 
i am actually confused why anwar's answer was accepted
 
@KazWolfe in my opinion anyway
 
don't know. I was thinking he will accept your's
 
Well I'm still new, so point me towards the fun things
 
really he should have!
 
7:11 AM
it is not wrong but OP already commented out force_color_prompt
 
no @edwinksl more than that, he had never uncommented it
 
may be because of my comment "exit terminal and start again" :)
 
it is commented by default
 
@Zanna ah yeah that was what i meant :P
 
I am just clarifying, I know you know
 
7:12 AM
alright let me play the bad guy here and ask OP
 
@edwinksl don't :)
 
So there's a +500 question.
 
meh, no worries, cheap points in any case... but I think my answer did what he actually wanted
 
^ I agree
 
he never had a coloured prompt to uncolor hahaha
 
7:15 AM
how do i know? because he said he did many things to turn if off
 
i am merely asking from a neutral POV and i want to understand why OP did what he did
 
kk
 
true :)
 
but i really should go to bed
 
7:16 AM
haha I love that, it's so true
did James undelete his answer? I think I just lost one point
 
hmm i haven't lost one point yet
 
maybe what I've lost is count....
 
what 1 point?
 
hey my rep is doing weird stuff...

7:54 AM
@ByteCommander I started my power-flow indicator and started tail -f /var/log/syslog. I don't see /var/log/syslog change as the indicator changes. Also, it says "gnome-session" , were you using it on gnome ? Perhaps they have some mechanism that records panel information and throws it into syslog. If this was just label itself , it would also include the "W" for watts or mA for milliamps . I don't it's my indicator but it could be some other utility.
I mean I am running tail -f /var/log/syslog right now as i type this , and it doesn't change at all
 
why don't we have ?
 
@Anwar ooh lemme create a tag...
 
it is more than bash but also not quite full ubuntu
 
^ that one is confusing imo
I can run ubuntu on windows with VM
 
7:58 AM
i prefer calling it WSL
seems like m$ is also calling it WSL nowadays
 
@Zanna created one :)
they named it long ago. i remember there was an option in win7
 
I am writing tag info now haha
 
they are popularizing it now
 
bash on windows is misleading too
 
how?
 
7:59 AM
it is clearly more than just bash
 
so i shouldn't write tag wiki?
 
hmm.. i haven't used them
don't know
