One liner for ad blocking on Ubuntu phone/tablet commandlinefu.com/commands/view/17368/…

@Videonauth that would be awesome @NathanOsman you should totally answer emails to george ;)

Videonauth

:) he did in my case

but i guess my bribe was not high enough to make him endorse me in the election xD

kidding

user139252

4:19 PM

Is there a way to keep your gpg key across computers?

Videonauth

sure you can export them and import them

Mateo

You should be able to back it up I think

user139252

Alright. I'm already in the process of making a new one, so I'll keep this one :P

Mateo

I did it once, but found it was easier to make a new one and revoke the old

user139252

Yeah, that's what I'm doing :P

user139252

4:23 PM

It's saying there isn't enough randomness....

Videonauth

yeah keep it running for a while and simply do what you normaly do

user139252

I'm running a Python loop of while True: random.random() D=

Q: How do I create a 1GB random file in Linux?

I am using the bash shell and would like to pipe the out of the command openssl rand -base64 1000 to the command dd such as dd if={output of openssl} of="sample.txt bs=1G count=1. I think I can use variables but I am however unsure how best to do so. The reason I would like to create the file is...

linux dd

Zacharee1

@TheBrownOne don't you need a random seed or something?

user139252

@Zacharee1 The computer is just supposed to create entropy on it's own.

Zacharee1

4:32 PM

huh

user139252

I'm running a dd from /dev/urandom

user139252

There we go, that worked.

user139252

Takes about 10 minutes before Launchpad can see the key on the keyserver, right?

Videonauth

Are you nominating yourself @TheBrownOne?

user139252

Yeah, need to sign that code of conduct.

Videonauth

4:40 PM

oh cool :) well me too

Nathan Osman

Chat is acting up...

Android Dev

@Videonauth - Regurgitating what other answers said is OK? askubuntu.com/review/low-quality-posts/575499

Videonauth

@AndroidDev as i reviewed this there has not been a comment on it

user139252

I'm getting a "No Pub Key" error trying to submit my signed code of conduct.

Videonauth

then wait a moment, maybe the keyserver hasnt catched up yet ?

Android Dev

4:48 PM

@Videonauth - You mean muru had not left that comment when you looked at it?

Videonauth

exactly

i saw just an answer which looked legit with no comment on it

otherwise i would have opted for deletion

user139252

@Videonauth No, my key was successfully imported to launchpad

Videonauth

mhmmm

user139252

Fixed it.

user139252

I just redownloaded the code and resigned it.

Videonauth

4:51 PM

ah good :)

Android Dev

@Videonauth - Good. Just making sure that post wasn't fine.

Videonauth

@AndroidDev reminds me of that i should more often do checks on the question history itself tho

Seth

@chaskes oh hey! I see the open with vim thing now too!

cool.

user139252

Seth

Chat is still borked.

is chat still having issues for anyone else?

Zacharee1

5:04 PM

I think it's fine for me

What's wrong?

And whatever happened to @kos?

user139252

Italy was taken over by communists again?

Nathan Osman

@Seth see TL room...

Seth

it's super slow, sometimes messages don't send, and sometimes they don't come in until I reload the page

Nathan Osman

There are other problems too.

Seth

that's a good question. What did happen to @kos?

Rinzwind

5:08 PM

@Seth no problems here :)

Zacharee1

I'm having slight delays with sending messages, but I think that's it

I don't think I've refreshed since last night though

Seth

test

Rinzwind

test failed

press R to retry test or F to format your system. F will be the default choice if not entered R in 10 seconds.

user139252

Is @Jokerdino around, still?

jokerdino

@TheBrownOne yeah

user139252

5:14 PM

Up for a game?

jokerdino

Sure, what kind?

Videonauth

@Rinzwind youre going to nominate too ?

jokerdino

@Rinzwind lol

user139252

@Jokerdino A card game.

Rinzwind

@Videonauth naah :D

Videonauth

5:15 PM

Phew xD

Rinzwind

@jokerdino I guess we lost Seth due to formatting :=D

Seth

I think they fixed it?

user139252

Seems like it, @Seth.

Seth

yay it's working again

Videonauth

@Seth have as well issues today the site is somewhat slow

Rinzwind

5:17 PM

oh the formatting fixed your chat problems?
glad it worked :+

Seth

hah! :p

Rinzwind

2 new mods... we getting 2 extra? or 2 replacements?

user139252

Only the top 30 by rep advance? I'll probably not cut it.

Seth

@Rinzwind 2 extra

Rinzwind

cool :)

Seth

5:23 PM

@TheBrownOne we've never had 30 candidates..

Nathan Osman

Only Stack Overflow has ever had that many, AFAIK.

Seth

yeah

user139252

Oh, alright.

Rinzwind

the link at the stars points to the 2014 election :P

Nathan Osman

Not mine :D

Rinzwind

5:28 PM

@NathanOsman click the link named ...

"more information"

and I see "Ask Ubuntu 2014 Moderator Election"

"This election has ended. These are your new moderators!
Seth + Mitch"

:P

Nathan Osman

That's because it hasn't started yet...

Rinzwind

Ok fine. but would have been ehm more professional to remove the link until it does :+

Seth

that site isn't run by SE

and it doesn't know there's an election since it hasn't started, so it is showing you the only thing it knows.

Videonauth

@TheBrownOne maybe we both are the only applicants for the job then the election is fast done ;)

user139252

@Videonauth I wouldn't mind that :P

user139252

I promise to only abuse my powers 95% of the time!

Q: How does ls -l format its output so neatly?

How does ls -l format its output so that column contents line up neatly?

command-line

that would better fit on U+L I would assume (?)

user139252

I think so.

Videonauth

agreed

as i have commented as long no one really knows the source code of the ls command well theres no saying how they did that

Seth

5:39 PM

It's not off-topic.

Videonauth

not said OT but it still would fit SO better I think but thats only my opinion

user139252

No, but it is more universally applied, right?

Rinzwind

I know. But a U+L user probably will know the answer :+
I am having trouble finding the answer :+

user139252

AFAIK, ls -l works the same on all *nixes

Q: Why these condas take much space?

I am newbie in conda and trying to understand its environments. System: Ubuntu 16.04. I do but notice it takes about 28 Gb memory, which I cannot understand. sudo -H pip install conda conda create -n my_root --clone=/usr conda install ipython ipython-notebook jupyter I do not have multiple...

ubuntu anaconda

Rinzwind

5:41 PM

@TheBrownOne nope. But on all systems using GNU coreutils ;-)

user139252

Well, I don't know much, then :P

Rinzwind

if it was tabstops would setting it to 4 change ls output? :P

Videonauth

i meant within the c program and theere you can define how big they are what would be needed as well since the columns are always shaping on the length of user group names and bytesize

print_horizontal (void)
{
  size_t filesno;
  size_t pos = 0;
  size_t cols = calculate_columns (false);
  struct column_info const *line_fmt = &column_info[cols - 1];
  struct fileinfo const *f = sorted_file[0];
  size_t name_length = length_of_file_name_and_frills (f);
  size_t max_name_length = line_fmt->col_arr[0];

  /* Print first entry.  */
  print_file_name_and_frills (f, 0);

  /* Now the rest.  */
  for (filesno = 1; filesno < cwd_n_used; ++filesno)
    {
      size_t col = filesno % cols;

from ls.c

and there are actually 4 source files for ls in core utils

a long read if you really want to find out

Q: Noticed something about audits

I noticed something about review audits: When it's going to give me an audit, the page says, "Loading next item" for a long time (>4 seconds). Otherwise, the wait time is <1 second.

Seth

6:23 PM

hahahaha. Watching Casey Neistat's vlog. He has trouble with numbers (his own words) and yesterday his vlog said June 4, 2017. Then the next day he got to ride in a delorean! xD

Zacharee1

lol

Nathan Osman

Any Mac folks around?

Zacharee1

I know a bit about Mac

Or do you need testing?

Nathan Osman

Will this cable allow me to connect a DVI monitor to my Mac Mini?

amazon.ca/Yellowknife-Premium-DisplayPort-Thunderbolt-Adapter/…

Zacharee1

Which Mac Mini?

Aaron Hall

6:31 PM

The vast majority of your rep on this site is due to this answer, which I could have written based solely on the material in the top answer. You shoud earn your rep by writing a decent answer that says, at least in short and in general what the differences are. Hand-waving is a waste of time. Unless it truly is just an alias, in which case there shouldn't be any differences in syntax. And if you do, you'll reverse my opinion of the answer, but as it currently stands, it contradicts itself! Let me know when I can delete these comments. — Aaron Hall 19 hours ago

Nathan Osman

@Zacharee1 I bought it around March 2015.

Zacharee1

New?

Nathan Osman

Yes.

It has four thunderbolt connectors on the back.

I assume they can be used for video... but I'm not sure.

Zacharee1

Yes they can

But I don't think Mini DP and Thunderbolt are the same thing

I don't trust that cable

Seth

they're not.

they just use the same connector.

Nathan Osman

6:33 PM

Are you sure?

Zacharee1

@Seth ah, so this adapter should work then?

Nathan Osman

support.apple.com/en-us/HT204149

Seth

I would say no.

Zacharee1

That's what I'm thinking

Nathan Osman

> "Some Apple computer have a Thunderbolt port instead of a Mini DisplayPort. Computers with a Thunderbolt port will have the following symbol next a port although the port physically appears the same as a Mini DisplayPort:"

Seth

6:34 PM

> Are compatible with all of the Mini DisplayPort adapters referenced below in question 5 and with Apple Mini DisplayPort equipped displays.

so it might work for a monitor.

What are you planning on using it for Nathan?

Nathan Osman

Yeah, that's what had me wondering.

@Seth Driving a second display (@1080p).

Seth

Okay. Then I guess it would probably work.

Nathan Osman

The Mac Mini has an HDMI output but nothing for the second display.

Just four thunderbolt connectors.

Seth

The Thunderbolt spec is a combination of DisplayPort and PCIe something.

Nathan Osman

Yeah, so I'm guessing it would work.

I wish there was someone in the Ask Different room I could confirm with though...

Zacharee1

6:35 PM

I'd go for something that doesn't say it's for both

Seth

> The new port is backward compatible so it can still be used to connect to DisplayPort devices; however, only the new port can be used to connect to Thunderbolt devices.

Zacharee1

oh

Seth

From CNET here cnet.com/news/confusing-mini-displayport-with-thunderbolt

Zacharee1

there's your answer

Nathan Osman

apple.com/shop/product/MB570LL/B/…

Zacharee1

6:37 PM

$30, Apple?

sigh

Seth

@NathanOsman Thunderbolt is literally a combination of the DisplayPort protocol and the PCIe protocol. Chances are it will work.

Zacharee1

My phone's flash storage is really slow today

Nathan Osman

@Seth Thanks.

Zacharee1

slooooooow

Terrance

All of those connectors are $30 from Apple. I paid the same for my stupid ethernet connection since the new MacBook that work gave me doesn't have ethernet on it. :(

Nathan Osman

6:39 PM

The one on Amazon is like $7.

So I'm thinking of getting that if it will work.

Zacharee1

@Terrance is that the MB that only has one USB-C and nothing else?

Seth

@NathanOsman this is a bit more but looks a lot more reputable: amazon.com/Cable-Matters-DisplayPort-Thunderbolt-Compatible/dp/…

Zacharee1

oh definitely

Nathan Osman

Hmm yeah.

Zacharee1

and it looks real instead of 'Apple'

Nathan Osman

6:41 PM

Now I just need to find it on amazon.ca.

Zacharee1

@NathanOsman change the domain and see what happens :p

yup

amazon.ca/Cable-Matters-DisplayPort-Thunderbolt-Compatible/dp/…

Terrance

@Zacharee1 This one has Thunderbolt on it, as well as one USB connector.

Nathan Osman

@Zacharee1 Yeah, $29.

Terrance

2 Thunderbolt connections that is.

Zacharee1

@NathanOsman heh, well

anonymous2

6:42 PM

Remember, $29 CDN

Zacharee1

@Terrance sounds like fun

Wait, what's CDN? Isn't it CAD?

Seth

@NathanOsman I wonder how hard it would be to ship it from the US site to Vancouver..

Nathan Osman

It is.

Terrance

@Zacharee1 It drives me crazy! :(

Nathan Osman

@Seth Yeah, but often I end up paying duties on stuff that crosses the border.

Seth

6:43 PM

@anonymous2 still $22 USD :/

Zacharee1

@Terrance lol

Nathan Osman

There's this one: amazon.ca/BlueRigger-Mini-DisplayPort-Adapter-Cable/dp/…

Seth

(compared to the $10 USD it os on amazon.us)

Nathan Osman

We're down to $15 now.

anonymous2

Yep. CDN, CAD, CAN same thing.

Zacharee1

6:44 PM

@NathanOsman 6ft lol

Nathan Osman

CAD is the official currency symbol.

anonymous2

Yep.

Zacharee1

ah

Terrance

@Zacharee1 And my Synergy app dies on it at least once a day. :(

Nathan Osman

@Zacharee1 I only need like 3 feet.

Zacharee1

6:44 PM

weirdness

@Terrance oh, you use that?

Seth

@NathanOsman That's better.

Nathan Osman

It's sitting right underneath the monitor.

Zacharee1

@NathanOsman it seems long to me

But I guess it is the whole cable

Terrance

@Zacharee1 Yes. I have 3 systems on my desk at work that I use all the time. Sure beats using a KVM.

Zacharee1

@Terrance true

user139252

6:45 PM

I'm so close to 3K D=

Nathan Osman

amazon.ca/CNE11274-DisplayPort-Female-Adapter-MacBook/dp/… ?

Terrance

@Zacharee1 I have found though that using Synergy as the server on the Ubuntu box works the best. :D

Zacharee1

@NathanOsman I like it

@Terrance what a surprise

anonymous2

If you don't mind buying from China, ebay.ca/itm/…

Nathan Osman

@TheBrownOne I went to find some of your good answers to upvote... and realized I'd already upvoted them... :D

Seth

6:47 PM

@NathanOsman too short. Long is annoying, but at least it is always useful. Whereas short can get pulled out, or just plain not work for what you need.

Nathan Osman

6 feet should do it then.

Zacharee1

@Seth well that one is just an adapter

Seth

true. If you already have a DVI cable it would be fine.

Zacharee1

@TheBrownOne go close stuff now

user139252

Oh yay! :D

Nathan Osman

6:48 PM

@Seth I already have a DVI cable if that helps.

Forgot to mention that.

Seth

That does help.

Zacharee1

@NathanOsman how dare you

my phone is so hot right now I'm using it as a heatpad for my sore shoulder ;p

oh dear, another mod

Nathan Osman

@Zacharee1 I know the feeling.

Zacharee1

(literally)

Nathan Osman

I was filming George's video yesterday in 4K and the camera got the phone so hot I could hardly touch the screen.

Zacharee1

6:50 PM

lol

Ugh, I forgot how WHITE TW's S7 theme is

Like, why even have an OLED screen if you're going to make every element bright #FFF?

Seth

lol

Zacharee1

Ironically, this S7 MM port is faster than stock LL

I have a T-Mobile splash screen because this is a T-Mobile port :p

RPi Awesomeness

Wasn't there a way to install DEBs via apt-get recently added to 16.04?

I heard something on one of the Ubuntu podcast episodes

Seth

pretty sure it was out before 16.04.. but yes.

RPi Awesomeness

What is it?

Zacharee1

7:01 PM

You can?

Rinzwind

@RPiAwesomeness it is now "apt" ;-)\

Zacharee1

So, it installs dependencies as well?

RPi Awesomeness

I mean, dpkg -i DEB && sudo apt -f install

Zacharee1

lol

Seth

@Zacharee1 not sure. I think I might have used it once..

Zacharee1

7:02 PM

what is it?

user139252

@RPiAwesomeness Yeah, that's been around a while.

RPi Awesomeness

What's the command?

Seth

I tend to just use the software centre for .debs because it is easier to just click on them from the browser.

user139252

That

user139252

Just that :P

Seth

7:02 PM

apt-get install xxx.deb I'd imagine?

Zacharee1

really?

Seth

but the file will have to be in your PWD.

Zacharee1

pwd?

oh

working dir

user139252

Yeah, the dpkg and apt combo will attempt to install the deb, run into an error, and then apt will get the deps.

Rinzwind

sudo gdebi /path/to/filename.deb
works too if you install gdebi

Zacharee1

7:03 PM

hmm

user139252

I have an hour for lunch. Anyone (18+) available for a game of Cards Against Humanity?

Zacharee1

I'm 21 on Google

And I've played it; it's fun

Seth

Hi 21 on Google.

Zacharee1

@Seth shut

@TheBrownOne where do I play?

Seth

she's trying to find a private method to contact you :p

user139252

7:07 PM

Sorry, I was grabbing a snack :P

Seth

or she is grabbing a snack.

user139252

Let me set up the game

user139252

Go here: pyx-1.pretendyoure.xyz/zy/game.jsp#game=132

Zacharee1

7:10 PM

I see somewhere I can put a nickname

ah there we go

user139252

Yeah, choose a nickname first. Then it'll ask for password.

Zacharee1

We could also do Evil Apples

It's the same thing, but an actual mobile app

Terrible animations on Android though

user139252

My phone is a piece of junk :P

Zacharee1

Well then this app will run even better

@Seth join

Seth

nope

Seth

Maybe I will :P

Zacharee1

lol

He certainly has the credentials

Rinzwind

@Seth you could get an extra diamond as a "double mod"

Seth

@Rinzwind would I have to do double the work?

Rinzwind

@Seth noooooooo you'd get a whip! to whip mods into action!

Nathan Osman

@James That was PowerPoint 97 for the record.

Rinzwind

@NathanOsman btw, is 4 weeks of vacation really small in Canada or was that supposed to be a joke?

I can never tell because, apparently, Europe has much better vacation plans than the US.

Nathan Osman

Good question.

I guess I should have made it 5.

Rinzwind

@Seth 3 is the norm in Holland :-P but we get 24 days in total of which 3 weeks have to be in sequence.

Nathan Osman

Amazon does their own deliveries now?
