That bug-feature is definitely removed in 16.04

Her it's case sensitive.

Thanks for checking!

Kaz Wolfe

np

yeah. i love this PS1.

Zacharee1

Who wants an iMac from 2009?

$290

Kaz Wolfe

who wants a mac without spending a dime?

grooveplex

How can I close my question so that people won't have to answer it, but it will be still viewable and useful for the people from the future? askubuntu.com/questions/793260/installing-mate-alongside-unity

edwinksl

@grooveplex you should break up your post into an actual question and then answer your own question

Kaz Wolfe

6:14 PM

^^^^^

edwinksl

@grooveplex as it currently stands, it will probably be closed

Kaz Wolfe

AskUbuntu is NOT a forum!

I will repeat this until I die.

grooveplex

woah alright alright

keep calm yall

im working on it

James

Anyone here used ZeroTier before?

Kaz Wolfe

-3 and a close vote. woah.

edwinksl

6:19 PM

really? that is pretty fast :/

Kaz Wolfe

@James So... um... dumb question but what's the difference between a VPN and this?

James

@KazWolfe ZeroTier is more like a local VPN

grooveplex

I'm just trying to be HELPFUL

James

so by default, you join a ZeroTier network and it's LAN-only

edwinksl

@grooveplex i know, unfortunately people outside this chat don't know :/

Zacharee1

6:20 PM

@grooveplex I'm gonna make a few edits

Kaz Wolfe

@James Oh, I kinda see. It's basically like a virtual switch.

Okay, that's really cool. I like that idea.

James

by default, a VPN will route all your traffic out

grooveplex

And please revert those downvotes

They're honestly unacceptable

I'm serious

edwinksl

@grooveplex i didn't downvote (i in fact ran out of votes for today :/)

Kaz Wolfe

@James Is it centralized, or can you self-host this platform?

-4 / 2 CV

edwinksl

6:21 PM

@grooveplex i pinged you when it was still 0 up/down

Kaz Wolfe

You still don't have an actual question, @grooveplex

Thomas W.

cough

James

@KazWolfe Sorta. Download it and connect to 565799d8f6195739, and then you should be able to ping voyager and have my machine respond.

grooveplex

@KazWolfe I know. I just wanted to post how I did it in case anyone ever finds it useful

James

@KazWolfe I think it's still centralized for the management of networks, but looking at Wireshark things seem to go directly from A to B without passing through the centralized server

Kaz Wolfe

6:22 PM

Oh. Okay, I see.

Since this could come in lots of handy for linking servers within the same ISP privately.

James

Yeah, i found it earlier today.

my plan is to setup all my machines to do this so I can access everything anywhere.

Kaz Wolfe

hm. i wonder what happens if I put this on an internal network?

James

remove the need for port forwarding from my remote dev server to whatever device i'm using.

Kaz Wolfe

(for example, DigitalOcean's internal networking)

James

it creates a new interface

you'd need to use a bastion host for that

Zacharee1

6:24 PM

@grooveplex edit your answer to have steps instead of paragraphs. Split things up a bit

Kaz Wolfe

I like this ZeroTier concept.

brb installing it on prod WITHOUT TESTING!

because honestly, who tests on anything but prod?

James

yeah, pretty much

grooveplex

I will do it asap

afl

edwinksl

@grooveplex also remove the "this is not a question" quote at the top

Kaz Wolfe

@Zacharee1 beat me to it

Zacharee1

@KazWolfe there's a button called "ethernet bridge"

This looks interesting: zerotier.com/community/topic/5/…

Kaz Wolfe

okay, yeah. I'm definitely going to look at this in a lot more detail when I get over to Job 2 from Job 1.

Zacharee1

are we breaking production machines or laughing at @ParanoidPanda's nefariousness?

gud

Kaz Wolfe

@Zacharee1 Yes.

Zacharee1

ah

yes

Kaz Wolfe

(actually i take prod testing really seriously for everything except major incidents -- see security threats)

Zacharee1

@grooveplex so yeah, even though you are making a guide, you need to make the question a question and answer it in an answer. It's so it's open to others who may have other procedures or updated ones.

edwinksl

after so many mint questions, we finally have a mac os question askubuntu.com/questions/793268/…

6:47 PM

@ParanoidPanda regarding your question here askubuntu.com/questions/793274/… you better refer to the main-board manual for checking which ram types are supported and refer to the BIOS it self for checking which ones are in and which clocking they have.

user136984

@Videonauth: I thought there were Terminal commands one could run to find out this information (I've run them before, just can't remember what they are)?

Videonauth

I'm not sure if there are any which provide so much detailed answers, just telling you what i would do for finding out :)

Zacharee1

@ParanoidPanda the problem is you don't specifically ask that

and there's no implication beyond a tag

There's a slash missing as well.

Anyone know if there is a like a guide or something to easily manipulating ArrayLists (especially 2D ones) in Java? :)

Byte Commander

Simply use Python.

user136984

@ByteCommander: Don't like Python. :P

user136984

Plus, this is a tool which is for a Java IDE so it doesn't actually allow you to write it in anything but Java.

user136984

It's fine, I'll figure it out.

Byte Commander

What exactly do you need?

(except Python)

user136984

7:43 PM

To understand how to properly manipulate a 2D ArrayList. That is how to add, remove, and reorder entries, as well as entire rows.

Byte Commander

ZX Spectrum

The ZX Spectrum (UK /zɛd ɛks ˈspɛktrəm/) is an 8-bit personal home computer released in the United Kingdom in 1982 by Sinclair Research Ltd. Referred to during development as the ZX81 Colour and ZX82, it was launched as the ZX Spectrum by Sinclair to highlight the machine's colour display, compared with the black and white of its predecessor, the ZX81. The Spectrum was released as eight different models, ranging from the entry level with 16 KB RAM released in 1982 to the ZX Spectrum +3 with 128 KB RAM and built in floppy disk drive in 1987; together they sold in excess of 5 million units worldwide...

So I'm putting the derpbuntu stuff on Imgur. Should I put in watermarks?

Byte Commander

@KazWolfe From man ln:

       -d, -F, --directory
              allow the superuser to attempt to hard link directories (note: will probably fail due to system restrictions, even
              for the superuser)

Kaz Wolfe

It does fail.

Byte Commander

8:16 PM

But it still fails with sudo ln -d on my system as well.

Kaz Wolfe

Meaning root is not all-powerful. Whuich is annoying

Byte Commander

If that does not work, probably it's impossible.

Videonauth

@Zacharee1 check the license which is put on imgur for the pictures, i dont think it makes much sense putting watermarks.

9:22 PM

Okay, here it is:

Russian reversal

A Russian reversal is a type of joke, usually starting with the words "In Soviet Russia", in which the subject and objects of a statement are reversed, usually to reference the propaganda of an enemy that is the exact opposite of the interlocutor. The jokes are usually told in broken English, without articles, in the way that a native Russian speaker might, which makes such reversals easier. A Russian reversal is an example of an antimetabole, a transpositional pun, and a chiasmus. == Examples == Examples include: In America, you find party. In Soviet Russia, party finds you! In America, you watch...

Android Dev

But it only accepts a single-dimensional array.

user136984

@Videonauth: Ok... Still not getting how it's actually funny... But ok...

Android Dev

@ParanoidPanda - Any insight?

user136984

@AndroidDev: Sorry, so what exactly does your array look like and how exactly are you converting it back?

Videonauth

9:26 PM

@ParanoidPanda for that you need a special kind of humor which isn't available on panda systems yet :D

Serg

He's probably doing hexdump of the image , right ?

Android Dev

@ParanoidPanda I'm creating the array like this:

`//Convert the 1D byte array into a 2D int array
System.out.printf("Converting image into a 2D integer array... ");
final int pixelLength = 3;
for (int pixel = 0, row = 0, col = 0; pixel < coverImagePixels.length; pixel += pixelLength) {
int argb = 0;
argb += -16777216; // 255 alpha
argb += ((int) coverImagePixels[pixel] & 0xff); // blue
argb += (((int) coverImagePixels[pixel + 1] & 0xff) << 8); // green
argb += (((int) coverImagePixels[pixel + 2] & 0xff) << 16); // red
result[row][col] = argb;

Serg

@AndroidDev use paste.ubuntu.com , and just provide us the link. Gonna be much less clutter

Android Dev

@Serg Okay.

Serg

Also, what's the purpose of splitting image into 2D array , I am not quite getting the purpose

Android Dev

9:32 PM

@ParanoidPanda @Serg - Sorry, the indents are messed up. Here it is: paste.ubuntu.com/18196706

@Serg I am going to manipulate the individual pixel's color codes.

Serg

@AndroidDev i see you're converting int array to string array there, but do you convert it back to int array ? Also , if you know the structure of one dimensional array, can you just reverse the process ( i mean convert 2d back to 1d array and give it to raster.setPixels() ) ?

user136984

Ubuntu 16.10 Alpha 1 released today!

Android Dev

@Serg Correct. I cut out the part where I manipulate the hex codes.

Videonauth

@ParanoidPanda you have a link to the iso?

Android Dev

@Serg And at the bottom where you see "editedImageIntArray", that's where I convert it back to an int array.

Serg

9:39 PM

But that's still 2d int array , int[][] editedImageIntArray = new int[height][width];

you said raster wants 1d array
