LOL

Nathan Osman

lol

Should I report it as a bug? :P

Rinzwind

would be a good idea yes :) it'll improve "file" :)

Android Dev

@NathanOsman And the verdict?

TheWanderer

guilty

Android Dev

lol

Nathan Osman

17:04

@AndroidDev I added the actual file output to the question.

dpkg should be installing the dependencies automatically.

I know it installed libc6:armhf.

Android Dev

@NathanOsman Are you sure? Does /lib/ld-linux-armhf.so.3 exist?

Nathan Osman

Yup.

# stat /lib/ld-linux-armhf.so.3
  File: '/lib/ld-linux-armhf.so.3' -> 'arm-linux-gnueabihf/ld-2.23.so'

# stat /lib/arm-linux-gnueabihf/ld-2.23.so
  File: '/lib/arm-linux-gnueabihf/ld-2.23.so'

Android Dev

Hrrrm

I was going to post an answer saying to install libc6:armhf and do a symlink to /lib/ld-linux-armhf.so.3 but I guess you've already done that :D

Nathan Osman

That was done by dpkg.

Android Dev

Do other 32-bit programs work?

Nathan Osman

17:09

Nope.

I haven't been able to get any to run.

Android Dev

The other thing I found on like page 4 of google was some random forum guy saying the kernel needs to be built with a special paramter

shrugs

Nathan Osman

I saw that too.

But I checked and the kernel has that parameter set.

CONFIG_COMPAT, IIRC.

I can confirm it's set: github.com/scaleway/kernel-tools/blob/master/aarch64/4.9.30-std/…

Android Dev

hmm there's also an SO answer saying you need a paramter

3

A: Can old ARM32 binary files be run on AARCH64 kernel?

Thank you moonbutt74. You had provided an useful clue for me to seek the solution to that issue. To enable the support of running ARM32-Linux programs on AARCH64 kernel, the option in the kernel should be selected: run make menuconfig ARCH=arm64 go to the option and select it: Userspace bina...

Nathan Osman

Yup, "Kernel support for 32-bit EL0" is the CONFIG_COMPAT parameter.

Android Dev

"The armv8 processors can run in 32bit mode (like the Raspberry Pi 3 currently does) but the Linuxes do not support a mixed mode."

Interesting --^

Probably wrong though

Nathan Osman

17:16

@GeorgetheDev is i.stack.imgur.com down?

Android Dev

@NathanOsman Is there any way I can easily set up an ARM64 VM so I can test the various solutions?

Nathan Osman

@AndroidDev I can give you access to mine - it's just an empty server on a cloud provider.

Can you paste your RSA public key?

Android Dev

Public RSA key?

Nathan Osman

cat ~/.ssh/id_rsa.pub

(Assuming that's where you put it.)

Android Dev

I don't recall ever creating one

Nathan Osman

17:18

Oh.

ssh-keygen

That should create one for you.

Android Dev

Should I give it a passphrase?

cl-netbox

@AndroidDev what ? :D

@AndroidDev yes - of course ! :)

Nathan Osman

@AndroidDev not really necessary

But you can if you want.

Android Dev

@cl-netbox I can SSH just fine without creating one..... I have keys for other machines; I never had to create one

@NathanOsman ssh-rsa AAAAB3NzaC1yc2EAAAADAQABAAABAQDTP3izKP8e6Z6e/pFEHB1IatkRCJ4v5l/EMLqA641sLH+A9ljV‌BrWVv6KeLRA34YU6fRebbcp2bseqda9ioPkziXzzjvGXSs0MmbrCYxZkwrKOWo9XUve1/dECKdpdxYkCB‌Yvr7aXsrHZH463Czqvh9+YXafOarRD/TjCp/11I7Upavt/PzsM94hSo15xoyuL83EPqOHqe0uKv1zPaRc‌RYml+t/hkBPNST4r6jHNxVq0RCen+Hd3+ZqJz8AKwzDTm/MM4nvCe0qfcq1P8T2ra4VgM6wRHF9hYMCl+‌FsgkTm14/MKC8r8dMvpI+vdbNmOZiD65bBMoQfe199t/COm45

cl-netbox

@AndroidDev that seems not to be the public key

Android Dev

17:22

@cl-netbox eh?

Nathan Osman

@AndroidDev you should now be able to do:

ssh [email protected]

Have at it :D

TheWanderer

ooh

time for DDoS

Android Dev

@NathanOsman Host key verification failed.

Nathan Osman

(Sidenote: normally login as root over SSH is a bad idea. This is for testing purposes.)

Wat.

TheWanderer

>_>

Nathan Osman

17:24

@AndroidDev try again

Android Dev

@NathanOsman Nope. Does it need the user@hostname at the end?

Nathan Osman

It shouldn't...

Kaz Wolfe

It does not.

cl-netbox

@AndroidDev ssh-keygen -t rsa -b 4096 creates a safe key

Kaz Wolfe

Host Key Verification Failed is something on your end iirc

@cl-netbox There's an even safer way to create a key.

cl-netbox

17:26

@AndroidDev give him your PUBLIC key

Nathan Osman

I added the key to ~/.ssh/authorized_keys

Kaz Wolfe

@cl-netbox That is his public key.

Nathan Osman

@cl-netbox that is a public key.

Android Dev

@cl-netbox that came from cat .ssh/id_rsa.pub

Nathan Osman

The private key is PEM-encoded.

It won't be in that format.

Android Dev

17:27

Well SSH says this:

ECDSA key fingerprint is SHA256:fUIiYafjieko6dgiusCPtFqCWrWs32pRLepDG293pQg

Kaz Wolfe

this is what a private key looks like, @cl-netbox:

Android Dev

So does the hash have to match?

Kaz Wolfe

compared to the public key:

TheWanderer

>_>

Kaz Wolfe

ssh-rsa AAAAB3NzaC1yc2EAAAADAQABAAABAQCl1bd3Tt1VpBThin3IsyuDqfhdFTO0Cra+DTyxfCukX1XEgduaGuKoMZZxpZJ/S9H3+gNucbQpKrkxqOrt2JouAOorJa0wOY1kWZ8Q1C8jZx5IGRlgl1eRIMDK4kmP2VHqX7Ahb8WZ5/DDT7fu7oLJtTjCii2huQ0SYF7xMl8qtwpWGfAK7xFYYHlEiica4jSRaQJO7hUaUpBy+Hr/2c4V9UUy3+isyAwNd27s8aG4uX68KLhhJuEl8G2ul1zLONwTXs7/kK3GknM4fWF5mCEU9eVeEMdd9MmDAXa9aJA12fj5soRt6Gvvz1NSsd7qUcO4FwaL95/GaKUhvOgZiC7F kazwolfe@firewolf

(and yes, that is a sacrificial key)

Nathan Osman

17:29

It's the public key so...

Not really a problem to disclose.

Kaz Wolfe

@NathanOsman see above.

Nathan Osman

Oh, the private key.

Android Dev

@NathanOsman Got it working. Wants root's password

Kaz Wolfe

@AndroidDev then you didn't.

cl-netbox

@KazWolfe yup ... I know ... and the public key ends with something like user@something

Kaz Wolfe

17:30

@cl-netbox not always. that's a comment

Nathan Osman

If it's asking for a password, that means key authentication failed.

cl-netbox

@KazWolfe true - but by default it has a comment - right ? :)

Nathan Osman

...and by default it reverts to password-based auth.

Kaz Wolfe

@cl-netbox my own public key looks like this: [...] DiraNpZgtxV8Q== cardno:000605426007

and yes, it usually has a comment. not always, and not necessary

cl-netbox

@KazWolfe I changed my one manually afterwards because the comment was the hostname of my main machine after key creation. :)

Android Dev

17:36

@NathanOsman Try adding this

Rinzwind

so did any linux user get hit by the new ransomware? >:)

cl-netbox

Rinzy ! :)

Bytey ! :)

Byte Commander

o/

Android Dev

@NathanOsman That second one has the hostname in it. We'll see if it makes any difference.

Rinzwind

Bytey! Boxy!

Nathan Osman

17:39

@AndroidDev okay, try it now

Byte Commander

Rinzy! Boxy!

Nathan Osman

17:40

Yup.

@AndroidDev you're in

Android Dev

So why does it need the hostname?

Byte Commander

You know, I'm still stuck in the past...

Will probably watch the episode where Rose dies, if I remember the preview from last week correctly

TheWanderer

Q: Can white eggs be considered as non-vegetarian?

I am basically a vegetarian and I find it very difficult to get an actual biological answer for this question on search engine. There are couple of links which discuss these argument but can not be acclaimed as a proof as being Egg either a veg or non-veg food item. Below are couple of links whi...

TheWanderer

@KazWolfe tell that to Google

Kaz Wolfe

@terdon Vegetarianism

terdon

@KazWolfe Yeah, it's the utter ignorance of basic biology inherent in the question that got to me.

Android Dev

@NathanOsman So why can't you just use the 64-bit version of traceroute?

Nathan Osman

I can. But traceroute is just an example.

Thomas Ward

17:58

coughs

Nathan Osman

What I really wanted to do was run Docker.

But I asked about traceroute since it is a far more simple application.

TheWanderer

@ThomasWard no

Android Dev

@NathanOsman Yeah, I installed hello and it has the same issue

huh

Thomas Ward

@TheWanderer shush. :P

TheWanderer

no

Nathan Osman

Hello fellow mods. I too am a mod.

so @NathanOsman how about that app huh?

(any time?)

Nathan Osman

Ducks.

Not yet.

Byte Commander

18:04

@NathanOsman I just saw you starred link to the Skylake issue... You know anything about when the intel-microcode patch will be available for Xenial?

TheWanderer

<_>

Nathan Osman

@ByteCommander Nope. No idea.

Byte Commander

Or is there an inofficial way to get it?

TheWanderer

learn binary

Byte Commander

Not sure if it would be that important, I can't remember any issues I would blame on that...

Android Dev

@NathanOsman Isn't there an ARM64 version of Docker?

@ByteCommander For Skylake, Intel has a patch, IIRC.

terdon

Nathan Osman

@AndroidDev Nope.

Just armhf.

@terdon lol

Byte Commander

I guess I'll just wait for the updated xenial package...

Android Dev

@NathanOsman Ahem I just installed it....

@NathanOsman --^

Nathan Osman

@AndroidDev Yes, but that's the one from the archives.

It's grossly out of date.

Sorry, I forgot to mention that part.

What I meant to say is that Docker itself doesn't provide arm64 builds.

Android Dev

Ah

Nathan Osman

Their official install script doesn't support it at all.

Android Dev

Ok, well back to trying to run armhf then :D

Nathan Osman

18:11

:D

Android Dev

Well, let me purge it before I forget

TheWanderer

why not just use an armhf OS?

@NathanOsman so you can't do the backend stuff atm, but you wanna help me get cookies going?

however that works

Nathan Osman

@TheWanderer Can't - it's a cloud machine and that's all they provide.

TheWanderer

oh

yuck

Priya Bansal

@terdon that doesn't surprise me.

americans are not known for intelligence. source: am american

i blame our lax schooling system.

TheWanderer

oh my god

I was giving them the benefit of the doubt and thinking they were talking about the eggwhite

but no

they mean white eggs!

christ

Nathan Osman

You have to plant an egg seed.

And grow an egg tree.

Duh.

TheWanderer

@NathanOsman ( ͡° ͜ʖ ͡°)

so about those cookies

cookesh

Nathan Osman

(Hey, there is such a thing as an eggplant.)

TheWanderer

eewwwwwwwwww

Nathan Osman

18:18

Is not as good as bacon.

'Cuz nothing is.

TheWanderer

I hate eggplants. Everything about them is gross: slimy texture, almost no taste except weird bitterness, chewy/tough skin

Seth

alas this is true

TheWanderer

@NathanOsman I'm gonna say a good bagel with creamcheese comes close

Nathan Osman

I can't stand cauliflower.

TheWanderer

have you had it right?

needs to be stirfried in garlic

Nathan Osman

18:20

I have had it. I did not like it.

TheWanderer

hrmmm

Nathan Osman

Even the smell of it cooking is not good.

TheWanderer

weird

I never thought it had much smell or taste

Nathan Osman

Some people put it in soup. This ought not to be done.

Seth

cauliflower is pretty awful too, yes.

broccoli is ok

Android Dev

18:21

@NathanOsman I'm not so sure that the kernel options you linked are correct. For example, CONFIG_IKCONFIG_PROC is set, but there's no config.gz in /proc

TheWanderer

how about white broccoli?

Android Dev

cauliflower?

Seth

I think I've had decent cauliflower in a good stirfry a few times, but it's not the norm.

TheWanderer

no @AndroidDev

white broccoli is broccoli

Seth

not sure I've ever had that.

Android Dev

18:22

Ok random poll: are cheeseburgers better with bacon?

terdon

@KazWolfe For what it's worth, that user was not American. Or, at least, not a native speaker of English.

TheWanderer

@AndroidDev YES

@terdon that's what I was thinking

"how does Kaz know they're American?"

terdon

@AndroidDev Everything is better with bacon.

Bacon is better with bacon.

Nathan Osman

@AndroidDev Yeah, that seems to be disabled.

TheWanderer

I've had maple bacon donuts: better with bacon

terdon

18:24

Even asparagus is better with bacon.

Apr 12 '15 at 0:24, by terdon

@hbdgaf Asparagus is always healthy! That's why I wrap it in bacon.

Android Dev

@NathanOsman What do you mean? It says y in the github you linked

Nathan Osman

Oh.

Yes, good point.

TheWanderer

@terdon asparagus heads are good

the rest, meh

Seth

@AndroidDev yes

@TheWanderer you have to get it while it's small

Grocery stores often try to sell asparagus that was picked way too late.

Nathan Osman

Peppers are good fresh.

TheWanderer

18:27

which peppers

Seth

thai dragon ( ͡° ͜ʖ ͡°)

Android Dev

@NathanOsman Yeah so that makes me think that the list you provided on GitHub is inaccurate

terdon

Dragon's Breath (chili pepper)

This article is about the Chili Pepper. For the Shotgun round of the same name, see Dragon's breath. Dragon's Breath is a chilli pepper cultivar developed in St Asaph, Wales, in association with Nottingham Trent University. It has been tested at 2.48 million Scoville units, which would make it the hottest chilli on record, surpassing the Carolina Reaper. == Development == The chilli plant was grown by Mike Smith, a grower in St. Asaph in Denbighshire, who said that he had not planned to break the record for chilli heat, and was named Dragon's Breath for the Welsh dragon. The plant belongs to Neal...

> One person who tasted the pepper had a numb mouth for two days;

Seth

that's hot

TheWanderer

>_>

Android Dev

18:35

@NathanOsman why is /boot empty?

TheWanderer

cookesh

@NathanOsman I think we need the cookie: sechatusr

I just have no idea how to get that..

Seth

steal it.

TheWanderer

>_>

Android Dev

Steal the cookies? :D

Seth

>:D

Android Dev

18:39

Or better yet the entire cookie jar

Seth

too noticeable

Android Dev

Hey wait a second, I just realized that all cookie jars must be created in Java! :D

(Get it? A JAR file)

TheWanderer

would it be plausible to create a private room for testing? @Seth

@AndroidDev shut

ChatExchange testing, that is

Seth

@TheWanderer no

why?

TheWanderer

darn

we need a way to test joining private rooms

and I don't have any private rooms

Seth

18:41

hm

I'm sure Nathan can test that.

TheWanderer

oh wait I know

chat.stackexchange.com/rooms/222/web-applications

that room only works logged in

for whatever reason

Android Dev

But non-mods can't even join a private room

TheWanderer

@AndroidDev yes they can

Kaz Wolfe

they can if they're invited

Android Dev

Does the app really need to support them?

Seth

18:43

honestly the requirements shouldn't be different than signing in.

TheWanderer

@AndroidDev that was the plan

and also gallery rooms need to be supported

private rooms are just the easiest way to test that right now

Seth

if you are really desperate ping a CM in the Tavern

Kaz Wolfe

Private rooms are very different from gallery rooms.

Seth

but I'm pretty sure they'll tell you know. Private rooms are strictly for moderation purposes only.

TheWanderer

Nathan Osman

18:47

@AndroidDev yeah, I have no idea why /boot is empty.

TheWanderer

we also have that issue @AndroidDev

Nathan Osman

I can't find the kernel image itself anywhere.

No idea what Scaleway does to make that work.

TheWanderer

maaaagic

Android Dev

@TheWanderer You must have broken something :P

@NathanOsman Yeah I was trying to find the kernel image to extract the options from it, but :\

TheWanderer

no that's what happens with small displays

Android Dev

18:51

Oh I see the issue

you have too much padding

TheWanderer

that's your RelativeLayout

Android Dev

we should make the padding proportional to the display density

TheWanderer

@NathanOsman would this be the correct syntax to pass into RequestFactory? "Set-Cookie: name=sechatusr; content=t=NETipskrs%2bbmhDM1HqswLwfyvDthu2SS; domain=chat.stackexchange.com; path=/"

Seth

@TheWanderer but but but.. hamburger fragment slider :(

TheWanderer

wat

Seth

19:03

your slider is a button..

I'm not making any sense probably lol

TheWanderer

we don't have a DrawerLayout

Nathan Osman

@TheWanderer brb, and no, it isn't.

TheWanderer

blegh

Nathan Osman

@AndroidDev finally got an answer.

TheWanderer

I'm trying to figure out how to get the authToken string that you return in a result

ohh

1,000 closevotes reviewed! :D

Sergiy Kolodyazhnyy

This guy -> askubuntu.com/q/929640/295286 is likely on non-Ubuntu system. I've checked two Ubuntu versions , 14.04 and 16.04, there is no /sbin/rescan-scsi-bus binary in neither. VTC please ?

Also, yay, I lost 20 points yesterday for two users being removed. Duck

TheWanderer

gah what is the authTokenType??

Seth

@SergiyKolodyazhnyy that doesn't mean his ubuntu can't have it though

Kaz Wolfe

scsitools

Sergiy Kolodyazhnyy

@Seth Sure, doesn't mean he couldn't have installed some package. If they respond with a comment explaining themselves, I'll retract the vote, but otherwise - out it goes

Seth

19:27

@SergiyKolodyazhnyy That's not how this is supposed to work.

Sergiy Kolodyazhnyy

@Seth OK, so what do you suggest ?

Kaz Wolfe

yeah, scsitools is pretty easy to install. and would make sense if you have anything SCSI on your machine. Might even be mandatory in that case, idk

Seth

@SergiyKolodyazhnyy I suggest if you can't help the OP you move on. Can't solve every question.

Android Dev

@NathanOsman And?

Sergiy Kolodyazhnyy

Well, moving on. Although would be interesting to see what the user actually replies.

Seth

19:34

@SergiyKolodyazhnyy also:

➜  ~ apt-file search /sbin/rescan-scsi-bus
scsitools: /sbin/rescan-scsi-bus

(as Kaz tried to point out multiple times, tho without saying it directly)

Android Dev

@Seth You're suggesting we use a navigation drawer activity?

Sergiy Kolodyazhnyy

OK, I'll retract the vote then

Seth

@AndroidDev I mean, it just doesn't look like it's following the design guidelines. Not that that's a bad thing. But it says "sliding panel". The typical button for a sliding panel is the hamburger no?

@SergiyKolodyazhnyy thanks

Sergiy Kolodyazhnyy

@Seth comment removed, left only the formatting part

Seth

k, removed mine too

Android Dev

19:38

@Seth Yes, that is true, though keep in mind that the sliding panel in question is not for navigating between different places in the app, but rather for selecting a chatroom

Seth

@AndroidDev isn't that navigating different places within the app?

doesn't really matter what the backend is doing, only how it appears to the user.

Unless you mean you're using a slider as some sort of dropdown select menu.

Android Dev

@Seth Fair point. Well, I suppose we could consider changing it to a hamburger on the action bar....

Seth

@AndroidDev It's your app, you can do whatever you want. But as someone who lives with some people that can't figure out the most basic UI/UX elements I do wish more people would follow the same basic guidelines.

Android Dev

@Seth Yeah I hear you. We haven't really put a ton of thought into the UI yet, I think the plan is to get the basic functionality of the backend working first. Will you be a beta tester btw?

Seth

@AndroidDev sure!

TheWanderer

19:59

@NathanOsman this is what authToken equals:

prov=4aa08d24-f659-74bb-1393-008824d6231b;anon=311e1ec6-5bb5-48c3-89e8-859965c7‌39fd;usr=6iPRSZF/RIeaeznvKlcBrfIZp8baenWd/aVftrKiVxw=

but it doesn't seem to actually work
