RPi Awesomeness

12:08 AM

@jrg Basically you enable but not turn on Voice-over (enable it in Settings > General > Accessibility > Accessibility Shortcut)

RPi Awesomeness

12:24 AM

Then you triple-click to turn it on and the screen should go totally black

and how do i get out of it?

RPi Awesomeness

It seems to be triple-clicking again or telling Siri to turn off Voice-over

That's what I've had work

And my WordPress plugin is published... wordpress.org/plugins/go-cannon

Still has the old name though.

I'll have to fix that in an update.

not a problem on my iPhone 5S, iOS 9.0.2

which is odd @RPiAwesomeness

what are you running?

RPi Awesomeness

iOS 9.0.2 on a 2014 iPad Mini

I wonder if it's an issue with just our device somehow

12:28 AM

Oh,i've got the same device here too

i'll take a look in a moment

just your device @RPiAwesomeness

Well, I guess we're taking it into the Apple store :P

Q: How to easily tell what package something is in without knowing its command-line name?

I have read this How do I figure out what package something is in without resorting to Google? and understand how to tell what package a certain command is in, however I still have a problem, how do I tell what package a program is in if I don't even know how to launch through command-line becaus...

Q: How to find out the terminal command of an application?

I want to use some applications shown on the Unity Launcher in a terminal, but I need to know the appropriate command to run them. How can I achieve that?

unity command-line

one is asking for the command-line, the other for the package.. Seems to me it's practically the same thing.

1:27 AM

getting there on my scope:

2:02 AM

Does someone with enough reputation want to ask someone for some clarification? I'm still pretty new to the site so haven't reached that threshold but more information can really help us help them and I'm unable to add a comment and don't want to just ask a question in the form of an answer.

If so then the question is here: askubuntu.com/questions/681288/… And the clarification that I would request is for more information - how much (if any) internal storage do they have beyond the SD card? Searching indicates it may have a 4GB SSD and that's not mentioned.

Wait, no, I am mentally handicapped tonight. Ignore that.

2:57 AM

There we go. I'm past the threshold. I've also now learned how to link to the help center. I love learning stuff and some of the markup here is different than anything I've used before.

It's the best markup you'll ever use :D

and welcome to the site!

@Seth Thanks. I'm the same KGIII on Slashdot, etc... The markup is different but I'm sure I'll learn it as time passes and as I use it more. Appreciate the welcome. I try to learn a bit daily and helping others helps me to learn. That and it is nice to give back.

3:30 AM

Just bought one of these: yubico.com/why-yubico/for-individuals/github

Should arrive within a week or two.

ooh, that's interesting Nathan.

Yeah, I'm curious to see how it works.

4:14 AM

that's a nice GitHub mug in the video

github.myshopify.com/products/github-mug

^--- there's that

@NathanOsman thanks. I'm a bit amused the item description makes it seem like admitting we need to imbibe liquids is like admitting a problem

Heh.

4:32 AM

you up late, @NathanOsman ?

It's only 9:33pm here.

I'm in the PDT timezone right now.

alright :) I think I'm a bit too caffeinated to sleep properly (I'm EDT)

Ah, so it's 12:39am there :P

Yeah, you better get some sleep.

And I just cleaned out 21 GB of junk on my server. \o/

hooray! ... how big's the server? :)

40 GB :P

(So I cleaned up half of the space on the disk.)

Docker sometimes loses track of some of the volumes that get pulled and they get stuck on disk.

Every so often I have to clean them out.

Any idea what part of a chrome profile is broken if it doesn't load properly and address bar autocomplete with the right arrow key breaks?

nvm, you're a firefox guy. i forgot.

Nope, I switched to Chrome :)

Really? What changed?

Firefox was just too slow and unresponsive.

Chrome is much smoother on my hardware.

5:25 AM

Good to know. I'm on chromium not chrome, but it's very close to the same thing.

I'm on Chromium too.

Sorry, I say "Chrome" so easily.

But I prefer Chromium since I can manage it via apt.

Also, this is a brilliant idea kickstarter.com/projects/ostrich-pillow/…

kind of like cochlear implants huh

kind of. bone conduction audio sort of means silent headphones though. i just wonder what the volume range is though.

it would be nice to hear the world and your own soundtrack/input at the same time.

oops, nvm, bone conduction is entirely different

That actually looks pretty cool.

I'd love to try it.

these videos are always kinda amusing to me

they look so content

don't get me started. i have a lot to say about seemingly content people raising crowd funding on kickstarter and legal threats.

5:48 AM

is it possible to get you started on just an exec summary ? :)

yes. yes it is.

Can anyone say "Ubutab"...? :P

Is that how we're referring to the AU chat tab now?

No, the "Ubutab" was a rather notorious scam in the Ubuntu community whereby someone attempted to crowdfund a cheap Ubuntu tablet and then proceeded to disappear off the face of the earth.

6:03 AM

I hadn't heard, but I see the correlation.

The thing is... lots of people were pointing out problems with the campaign right from the beginning.

And yet, some people still fell for it.

(Random sidenote: our blog (2buntu) actually was contacted by them really early on asking for us to write about them. We didn't.)

FWIW, I'm working on the flask-json api since it seems all the major identity providers turned off xmpp.

Is that instead of XMPP?

Yes. If you have to spin up a server, it takes out the reason for XMPP, so you may as well just use flask from the gate. Makes sense when you think about it that way right?

Indeed.

Docker is really getting on my nerves. I have only these images on disk:

REPOSITORY                          VIRTUAL SIZE
hectane/hectane                     193.7 MB
wordpress                           512.8 MB
mysql                               324.3 MB
postgres                            264.2 MB
nathanosman/quick-media-solutions   420.9 MB

And yet somehow they occupy over 30 GB of space.

Somebody's math isn't right. Or there's a bug.

6:19 AM

I suspect it has to do with the docker virtual size. A linux install of 4Gb * 5 == 20 + half a gig *5 is a lot closer to 30, Not quite there, but then you have config blobs and additional details. I'ld take 6.5 Gigs and that readout, because you're using the same base image, but that is ridiculous.

Well first of all, almost all of those images derive from the same base image so it should only exist once on disk. The base Ubuntu image is 65 MB.

So I'm completely mystified.

Then I too am mystified. I was operating on the assumption that an install was 4G

No, it's a really slim base image.

I'm not arguing. I'm just telling you the assumption that made us disagree on expectations.

I know you're not :)

And I understand the confusion since a desktop installation is quite large.

user136984

It feels more like it should be a comment...

@ParanoidPanda it really is

user136984

I guess so... But it just doesn't really get me anywhere...

@ParanoidPanda no no no. it should be a comment

How come that offensive answer hasn't been deleted yet?

11:25 AM

It is deleted. I can't believe the quality filter didn't disallow that as an answer.

If word count in answer is long enough but any given word is more than 20% of the word count - it's probably not an answer.

Smoke detector found something, but it's deleted now.

@ParanoidPanda Do you know about Terminator?

user136984

@Zacharee1: I have heard about it, but never really used it.

@ParanoidPanda Like I said in my comment, I'm pretty sure you can group its windows, which will at least help you with the terminal

user136984

Yes, but can I customize it like I have done with gnome-terminal?

hi @hbdgaf how is the freezer going so fat?

1:10 PM

wait what?

so far? i haven't been trying to grow the freezer recently though, so either way it doesn't make a lot of sense.

didnt yo say something about changing sections at work?

oh yes, work. frozen. about once a year i "stock my freezer", make it fat, whatever... so i was confused and only realized my personal freezer.

ah ;)

yes, frozen is going well. down from 130 outs on a friday two weeks ago to 17 controllable outs after a week of fixing. i'm a little scared what they're going to do to me after i fix it to zero.

hopefully they'll just leave me alone and let me stay in my freezer.

nice, yeah - hopefully relize that to maintain that they need to keep you somewhere

1:16 PM

i don't know if you know, but we're having a hurricane off the coast here, so sales were RIDICULOUS this week. still made it to 17 controllable. So, it's double awesome, not just awesome.

wow

think, up by 58% one day... and still have it that low. my shelves should technically be empty.

im sad that the rainbow sherbet yougart was limited edition...

that was an empty spot at our local store

yeah, i have 40 or so uncontrollable outs.

Is this a good answer? askubuntu.com/a/681469/274320

@hbdgaf lol

I'm suspecting the brakes on the truck failed and he was trying to "swerve slow". Probably a tollbooth at the bottom of a steep incline.

@hbdgaf possibly

user image

With large enough trucks even "good" brakes fail because they overheat on steep inclines if overused.

In the US, we have turn-outs up in steep incline in the mountain areas with dirt barriers where trucks with overheated brakes can come off the road and crash safely.

"crash safely"

without endangering others

that's an oxymoron if ever I did hear one

What window manager am I using?

user136984

So if I wanted a new window grouping feature would I request it to them?

Wooops! Sorry @terdon, I meant to ping @Seth! :D

user139252

@A.B. so, what about BVB?

Yeah, sounds the same! :P

All I can think about is eating and food... :D

@HeatherBrown BVB? Don't like soccer :)

@ParanoidPanda gdm

Uhm window manager, sorry

@Seth have you moved my answer :)

user136984

@A.B.: Wait, so GNOME Shell or GDM is my window manager?

user136984

5:09 PM

Or am I getting confused here? :D

@ParanoidPanda GDM is the display manager associated with the GNOME window manager, I think

Just make a feature request to GNOME. It sounds like that's what you're using

user139252

@A.B. who in here was a BVB fan then? I forget too easily. I obviously need more coffee D:

GDM is your display manager

@HeatherBrown no idea

user139252

@ParanoidPanda GNOME shell uses Mutter as a window manager, GDM as a display manager, and Wayland as a compositor

user139252

You would request window grouping as a feature from the GNOME team.

5:20 PM

I really should have finished that flask app template deploy thing I was playing with a month ago.

user139252

GNOME is essentially just written as a plugin for Mutter anyway, so window grouping would just be an extension of that plugin

oh, the battery - it is plugged in

see the lightning bolt :)

I missed it, yeah.

Do you like the phone?

oh, yes

a few things I would change scopes wise, but really awesome.

@Mateo - question for you if you have a sec.

None of the phone stores have one of these phones to try it out a bit.

5:39 PM

and don't listen to the people complaining about no backgrounding

there is a app in the open store that lets you let an app backgound

@hbdgaf sure, I'll be heading home in a few. but will have my phone

Still playing with that card game thing. If there were buttons instead of drag and drop for gameplay, would that be a dealbreaker on you liking it?

Hmm, I guess it depends on how it is played

I know drag and drop would be better, but I'ld rather get something playable now than something perfect never.

Would it be like up/down arrows for card selection

Like stacks with buttons under them for select stack or slot in stack with select slot for building stacks.

5:47 PM

Sounds reasonable

Okay. Was just making sure clicking twice instead of one drag wasn't off-putting.

Q: Can't boot after Ubuntu 15.10 Beta 2 Install

After some software problems with Ubuntu 15.04, I installed Ubuntu 15.10 beta 2, I figured that couldn't be much worse, ant now I can't boot off of my hard drive, and even when I try to boot my Ubuntu USB drive I get a kernel panic. This is new, 2015 hardware, I'm pretty sure there are zero hard...

ubuntu kernel-panic

@blade19899 You'ld think that multirom would be "pre-existing work" that would take that patent apart.

But, I'm not a lawyer. I just downloaded it one day six months ago from XDA

@Mateo - decided to come at it another way. My next step is waiting for a clean build of UE4. The UMG supports drag and drop out of the box, there are LOADS of target platforms, and there's a json data exchange plugin.

6:53 PM

Ah, that would work

My new scope is now showing on uappexplorer: uappexplorer.com/app/color.mateo-salta

Yup. And then you don't need a full server. Just a flask end-point that reads json posts and verifies game logic. It's got to be lighter than running a UE4 server instance.

@RPiAwesomeness from 1st release. Linux always had those on the desktop

Well, not always, but it's been a very long time.

It's been at least 9 years.

(My first intro to linux)

9:02 PM

Yeah, I don't remember not having them and my first Linux was ~16 years ago.

I'm guessing they were implemented in UNIX long before Linux came around.

And certainly long before Ubuntu did.

@ParanoidPanda good news: I finished the script and most of the filming for George's next video. Should be ready either late today or tomorrow.

@NathanOsman by the way, I don't know if you saw my ping the other day, but I hope you haven't removed George from the chat on my account. All I wanted was that he not reply unless spoken to. And that too is just how I feel about it. I had no wish to impose that on anyone!
