Speaking of unclear, is this? Or is it just me not getting it? askubuntu.com/questions/442924

edwinksl

i don't really understand what's going on in the question

Zanna

That makes two of us at least...

edwinksl

OP appears to have ditched avconv in favor of ffmpeg

so probably no repro?

not sure

Zanna

3:10 PM

It might be possible to reproduce the problem if I could understand it!

edwinksl

looks like OP already gave up and abandoned the question

good luck getting OP to clarify :p

JAVA HAS REPL NOW?!

WOOOOOOO

Serg

what ?

Terrance

@Serg It's worse for sun reflection when you're driving and the passenger does that and blinds you. :O

Kaz Wolfe

Serg

4:33 PM

@Terrance at least you have legitimate reason to tell the passenger to stop doing that. I'm in a public place of sorts

Terrance

@Serg Good point. =)

Kaz Wolfe

so java is a bit more pythonic for learning eval now.

Serg

Stupidity that we call "college campus" is to make everything bright, everything open, everything uncomfortable. Administration totally has no idea what students really need - that's sleep, coffee, and maybe medication for nervous breakdowns because you've tons of homework and/or exams with a professor that is basically useless

But hey . . . how's everybody's day going otherwise ?

Kaz Wolfe

Elated now that we have REPL for java

this is amazing.

It's now official. Java > Python

Kaz Wolfe

Serg

@KazWolfe not so fast, boy

I don't see people writing shiz ton of appindicators and whatnot in Java

Kaz Wolfe

@Serg soz, we has repl

and we're too lazy to write app indicators

tho i might push a PR to you replacing all of your Python code with Java code :D

Serg

Nah, thanks , I'll stick with python for now

6:14 PM

In order to be able to upgrade to 16.10 I need to increase the size of the partition /boot is on. What will the name of the partition be and can I just use a LiveUSB to increase the partition size using something like GParted? And are there any other issues I should be aware of with changing the partition size? Like I heard about it potentially affecting other partitions.

Serg

@ParanoidPanda run df /boot ,what does it say ?

user136984

Filesystem     1K-blocks   Used Available Use% Mounted on
/dev/sda2         241965 140752     88721  62% /boot

user136984

do-release-upgrade says I need to clear something like 30MB but I have removed all but the latest kernel from there so I can't really do much else without changing the partition size, can I?

user136984

And last time I asked here everyone said something different, and they all said that everyone else's methods were bad so I didn't know who to go with and I ended up not going with anyone's method, but now I don't know what to do as removing old kernels is not the solution any more because there are no more to remove.

user136984

@Serg: Any ideas?

Thomas Ward

6:18 PM

@ParanoidPanda you're absolutely certain all the old kernels are removed?

Serg

So, /dev/sda2 is your partitions of interest. Boot up live USB and increase it's size however you please.

Thomas Ward

including ones that were not removed by autoremove?

user136984

@ThomasWard: Yes, certain of it.

user136984

I manually removed all but the latest.

Serg

What df tells me is that you have

user136984

6:19 PM

@Serg: And that can't cause any trouble at all with anything else?

Serg

90850304 bytes of free space there

user136984

Well, this seems to be the contents:

user136984

So it seems as though there is more in there than I thought.

user136984

But I did tell it to purge all but the latest kernel and I told it specifically which packages to remove.

user136984

6:21 PM

Is there anything from there which I can safely remove? @Serg

Serg

That seems to be it . . .

Does it complain about /tmp at all or only about /boot ?

user136984

Only /boot.

Kaz Wolfe

why tf do people have such tiny boot partitions?

am i the only one with a good 4 GB?

user136984

Well, in future I will manually partition, but this time I used the installer's auto option...

Serg

@KazWolfe autoconfigured by system , i suppose

Kaz Wolfe

6:25 PM

@ParanoidPanda what about these two:

-rw-r--r-- 1 root root 37266052 Sep  4 18:11 initrd.img-4.4.0-34-generic.old-dkms
-rw-r--r-- 1 root root 37278756 Sep  4 18:12 initrd.img-4.4.0-36-generic.old-dkms

Serg

278.8 Mb for me

Kaz Wolfe

also my college somehow makes amazing burritos.

user136984

@KazWolfe Yes, I was thinking about them. What are they and can I safely remove them?

Serg

@KazWolfe ikr ? There's a cafeteria where korean folks are making these amazing sausage wraps.

Kaz Wolfe

they look like pre-DKMS ramdisks

serg what is with your obsession with asian culture?

@KazWolfe I don't know, but i love it

Q: purging old kernels fails to remove old initrd files

Can't explain why... I assume it isn't safe to simply manually delete them, so some guidance would be appreciated. Here's a ls of my /boot directory (obviously, I'm running the 3.13.0-51 kernel): -rw-r--r-- 1 root root 1164671 Apr 15 09:03 abi-3.13.0-51-generic -rw-r--r-- 1 root root 165762 A...

kernel

Serg

Also,new recent obsession : blond Asian girls . . .

Kaz Wolfe

@ParanoidPanda They look safe as long as there's no kernel tied to them.

user136984

@Serg: I haven't met any blond Asians.

Kaz Wolfe

^--

i've seen dyed hair, but nothing natural before.

user136984

6:29 PM

And I don't really like blonds in general anyway though.

Serg

Huyna

@_@

user136984

Well, I don't mind them as people, but I'm not attracted to them.

Kaz Wolfe

a nice looking blonde is better than a bad-looking brunette.

also am i the only guy who just can't stand makeup?

Serg

@KazWolfe want to say something, but . . . i think that's kind of true . . .

@KazWolfe i don't really like make up either

user136984

@KazWolfe: That is another thing I can't stand about most people, unless it is done very well, it looks awful.

Kaz Wolfe

6:31 PM

really well, or done really lightly.

user136984

I'd prefer it not to be there at all, but everyone else seems to disagree with me for some reason...

user136984

@KazWolfe Agreed, lightly is better though or none at all.

Kaz Wolfe

as in, maybe some very minor touchups and cleanups can look better than nothing, but still.

if you go all out, there's something... uncanny.

user136984

Anyway, so you think that I can just delete these .old-dkms things? Do I need to do it through DKMS or am I safe to just delete the files?

Nathan Osman

If I lose the rest of my hair, it's because I've pulled it out.

I can't figure out where this 301 is coming from...

Kaz Wolfe

6:32 PM

@ParanoidPanda make a backup, but i tihnk you're safe

user136984

@KazWolfe I generally prefer people's natural look.

Kaz Wolfe

@NathanOsman shouldiblamecaching.com

user136984

@KazWolfe: So I can just do a sudo rm?

Kaz Wolfe

@ParanoidPanda i mean, i've met (and crushed on to no avail) girls that looked good without makeup, but looked even better with just very tiny minor touchups.

@ParanoidPanda yep

Nathan Osman

@KazWolfe I've bypassed the cache.

No difference.

Kaz Wolfe

6:34 PM

@NathanOsman 301s are still cached by the browser

Nathan Osman

I'm not using a browser.

Kaz Wolfe

i don't know why, but they're really sticky.

Nathan Osman

I'm making HTTP requests directly in a terminal.

Kaz Wolfe

oh, then...

Does wget or curl cache?

(though i've just stopped using 301s altogether. 302 works fine and i can reverse it without hell)

Nathan Osman

@KazWolfe curl shouldn't be caching.

Kaz Wolfe

6:36 PM

your server may be caching

Serg

Well, no homework is done, but at least I figured out my flickering indicator. yay

Kaz Wolfe

it had a 301 at one point, it cached it, and it's not letting go

Nathan Osman

curl -s -D - georgethedev.xyz -o /dev/null

Try it for yourself ---^

Kaz Wolfe

i wish i was in a programming class so that i can just accidentally do homework

Nathan Osman

WHO ARE YOU AND WHAT HAVE YOU DONE WITH THE REAL NATHAN OSMAN?!

Nathan Osman

You do realize WordPress is written in PHP, right?

Serg

@NathanOsman why does your domain point to george   ?

Kaz Wolfe

The real Nathan would never use WordPress.

Nathan Osman

6:39 PM

@Serg That's what we're trying to figure out... :D

Kaz Wolfe

apache config?

Serg

^ maybe that

Nathan Osman

I thought that at first too but... I can attach to the container itself and issue an HTTP request to the URL and it works.

Here's what I have: Traefik (HTTP load balancer) => Apache/PHP container.

I don't think WordPress is causing the redirect, so it's either Apache or Traefik.

Kaz Wolfe

so... is Traefik cacheing the redirect?

user136984

@KazWolfe: Well, I deleted them, that should give me enough space (it only wanted 30 more MB). I will try the upgrade now, wish me luck! :D

Nathan Osman

6:41 PM

(Although if anyone can come up with a credible explanation for how WordPress is doing this, I'm all ears.)

Kaz Wolfe

break a leg!

@NathanOsman simple: wordpress is dumb

and/or a plugin is 301ing it in a weird way

Nathan Osman

@KazWolfe I have restarted and rebuilt the container - no luck.

@KazWolfe But then why does it work when I issue an HTTP request directly to the Apache/PHP container?

This is so frustrating.

Kaz Wolfe

@NathanOsman are you making the request to the domain name or an IP?

Nathan Osman

curl does a lookup on georgethedev.xyz and sends an HTTP request to the IP with the Host: header set.

When I had it enabled, the HTTP => HTTPS redirect was working...

Kaz Wolfe

so... if you're requesting from inside the container, you're querying to 45.33.X, right?

or does your hosts reflect the container as georgethedev.xyz?

Nathan Osman

6:45 PM

The container is named "george".

But its hostname is bea6b7ce3c44, apparently.

Kaz Wolfe

but does /etc/hosts resolve georgethedev.xyz back to 127.0.0.1?

Nathan Osman

Hmm... good question...

Kaz Wolfe

what happens if you ping it from within the container?

Nathan Osman

127.0.0.1	localhost
::1	localhost ip6-localhost ip6-loopback
fe00::0	ip6-localnet
ff00::0	ip6-mcastprefix
ff02::1	ip6-allnodes
ff02::2	ip6-allrouters
172.18.0.10	bea6b7ce3c44

^--- /etc/hosts in the container

AHA!!!

It is the container issuing redirects.

172.18.0.11 - - [19/Oct/2016:18:47:29 +0000] "GET / HTTP/1.1" 301 214 "-" "curl/7.47.0"

^--- logs

Kaz Wolfe

thanks for da ip

Nathan Osman

6:48 PM

Er, that's an internal IP... :P

Kaz Wolfe

i know your internal IP now >:D

Nathan Osman

Yeah, and the second the container restarts you won't :D

AH00558: apache2: Could not reliably determine the server's fully qualified domain name, using 172.18.0.10. Set the 'ServerName' directive globally to suppress this message

Interesting...

Kaz Wolfe

you can ignore that

Nathan Osman

I still think Apache is at fault though.

Mateo

wow, that was stressful

but, it was a success!

the mx5 pro

bought an android one, flashed it to ubuntu

there is is next to the mx4

can note 4 have Ubuntu Touch on it ?

@ThomasWard how about I'll give you java in vi ?

@Mateo I thought about buying one of those but I couldn't find any in stock at the time...

@KazWolfe how to be hated by an entire school, unplug the inbound internet connection...

Mateo

@TheXed same, so I just had to get the android one...

TheXed

Yeah that was when I decided to get the OP2

Mateo

7:27 PM

yeah, it wasn't an easy process to flash it

Anwar

@ThomasWard he was using mint :(

Thomas Ward

@Anwar ANd you didn't notice the tag.

lockdown on the question is confirmed though, closed.

Anwar

@ThomasWard I noticed it. but Terdon said other day, if a question can be turned into an OT, we should not close it

I disagreed with him. But tried this time to see how that works

It has just become another point.

Thomas Ward

@Anwar If someone edits it to be non mint, I'm happy to reopen.

That's why there's 'reopen' buttons.

Kaz Wolfe

i should get wolfbot back up

Anwar

7:32 PM

@ThomasWard I would have removed the tag, but as you see, my suggestion for using gedit didn't work for them because mint removed it

or I don't know if they were using some other mint variants like mint-kde

Thomas Ward

well, it's closed. Next best thing is prune the answer, but meh

Wait you did that

Anwar

I did it already :)

Nathan Osman

7:54 PM

More hacking later and I think I may have found a possible cause.

I captured that request that Traefik is passing to Apache

And sure enough, it's using the container name as the host.

So maybe WordPress is doing this.

Thomas Ward

adjust the WordPress configs.

specify a different hostname

Nathan Osman

Well, I can work around this if I can get Traefik to send a correct HTTP header.
