nah, probably had space $INSTALLDIR /*

IanC

could be, but a typo would have the same result, since $INSTALDIR would expand to nothing

I'm always a bit paranoid with scripts that have rm

a small mistake and you have a clear home dir (in the best case scenario)

Guys, how does opacity work? Does 0 opacity mean the window is transparent ?

Kaz Wolfe

yep

IanC

0 is transparent, usually 1 is completely solid

someone here likes watching Vsauce?

Serg

12:37 AM

welp, setting opacity didn't do a thing

Mateo

12:51 AM

depends on what you want transparent @Serg

@IanC worked on the newest firefox for me

IanC

is firefox -v Mozilla Firefox 49.0? Do you have the flash plugin? @Mateo

Mateo

any of the flash are set to "never activate"

TheXed

what should I do with my web server?

Mateo

@IanC did you have anything else activated, that it might be trying to use, but might be buggy

ah, any javascript blocking on?

IanC

@Mateo I only have the Cisco Systems plugin, both you and @edwinksl have Widevine, maybe that's the missing plugin?

damn, I pinged edwinskl with no purpose lol

Mateo

12:58 AM

that just installed for netflix

although... let me try without

Zacharee1

poof, I'm in front

IanC

could you check if about:preferences#content has "Play DRM content" enabled? @Mateo

after you try vimeo without widevine

Mateo

yes, and I diabled it just now, that vid you linked still works

what hardware do you have

IanC

VGA compatible controller: Intel Corporation Core Processor Integrated Graphics Controller

Mateo

00:02.0 VGA compatible controller: Intel Corporation 4th Gen Core Processor Integrated Graphics Controller (rev 06)

hmmm

IanC

1:08 AM

would be weird if it was the graphics card though, youtube works fine, it's just vimeo and "vimeo like" embedded videos that are giving me a headache :p

Mateo

ah, maybe try installing restricted extras

I think it needs h.264

try install gstreamer

IanC

I didn't find restricted extras on dpkg -l nor in apt-cache search, gstreamer1.0 is installed though

oh, sorry, I did find restricted extras

ubuntu-restricted-extras

Mateo

libgstreamer1.0-0

IanC

installed, I'll try installing ubuntu-restricted-extras

Mateo

27

A: How to install the MPEG-4 AAC decoder and the H.264 decoder?

ubuntu-restricted-extras package allows users to install ability to play popular non-free media formats, including DVD, MP3, Quicktime, and Windows Media formats. To install ubuntu-restricted-extras package: Open a terminal by pressing Ctrl+Alt+T. Run this command: sudo apt-get install ubuntu...

this one installed too? gstreamer1.0-libav

IanC

1:16 AM

running sudo apt-get install ubuntu-restricted-extras, gstreamer1.0-libav isn't listed

Mateo

huh

gstreamer1.0-libav is already the newest version (1.8.2-1~ubuntu1).

on mine

IanC

isn't it recommended not to have flashplugin?

it's included in ubuntu-restricted-extras

Mateo

that is one reason why it is "restricted"

IanC

it's working now, thanks @Mateo

Mateo

yay!

IanC

1:23 AM

not sure if it was the flashplugin or another of the tons of libs from restricted extras :p

Mateo

what happens when you right click on the video

IanC

there are some options like view page source, inspect element

nothing apparently flash related

Mateo

huh, intresting

IanC

1:47 AM

well, I disabled flash, but I think later I'll purge restricted-extras and find the single plugin that was missing

don't like having tons of plugins I'm not even aware about, keeping it clean :p

Serg

So . . . apparently svg icons are better than others

because they scale up really nicely in indicators

Nathan Osman

I find SVGs look awesome at high-resolution but absolutely terrible at low resolutions,

Serg

Eh, ? How's this for an indicator menu item ?

Mateo

nice, did you get the big icons working?

Serg

@Mateo sort of. Indicators for whatever reason hate png icons, but with Ubuntu Kylin theme, I have whole bunch of svg icons, and i kept trying Rhythmbox, but then tried a random one, and . . .well, you see it in the screenshot

Mateo

2:00 AM

oh, a common formating that might look better is: "Usage: 29.7%"

Also - any way you can fake tab alignment

Serg

What do you mean , tab alignment ?

@Mateo

Mateo

kindof like this

Serg

Oh . . . . . Probably. . . .I'll try

Mateo

I did it in a scope once, by adding spaces to the smaller ones, well actually it ignored multiple spaces...

hm

ah, I remember - I used underscores on the scope

it might push the drive part too far over though...

Serg

2:24 AM

Doesn't seem to work nicely

I cannot align them

Mateo

oh well

Nathan Osman

@Serg I haven't forgotten about your indicator. I had to work overtime yesterday, it was crazy.

I will do my best to get to it tomorrow.

Serg

@NathanOsman it's alright, i'm sort of working on it, adding stuff. Take time with your tasks so far, it's not urgent.

Mateo

@Serg does it push the text to a new row?

Serg

No

let me just show you

part = part + " "*(30 - len(part)) + i[0]

This is how i'm doing it

And . . how it looks like . . .comes in a second

Mateo

2:29 AM

ah, you just moved them all forward, move all but mountpoint by different amounts of space

Serg

It's supposed to be same amount

i am doing 30 - len( string )

in each of them

Mateo

so the first one might just be a few spaces, the next one more spaces - because the word is shorter

forcing them to line up because each first word is a different length

IanC

I think the font isn't monospaced

just notice how small is the space the "i" character occupies

Mateo

resort to guess and check ;)

Serg

Le sigh . . .

IanC

2:33 AM

iii
ooo
both will have 3 characters, resulting in the same amount of spaces, ending up in a unaligned tab anyways. Can you change the font @Serg?

I never changed fonts on Gtk but I think it's possible, then you just need a monospaced font and it will work (I guess :p)

Mateo

nah, just use different sized spaces to make up for the smaller letters

cs.tut.fi/~jkorpela/chars/spaces.html

IanC

didn't know about those, this would do too, but he would have to change the code if he decided to change the label name (no big deal though, since they are static)

Mateo

Partition: DATA
Alias: DATA
Drive: DATA
MountPoint: DATA
Usage: DATA

IanC

man, I'm trying this chess learning website, I'm lucky there's no clock on each exercise play

Mateo

ah, anyway might be to complicated - especially if different desktops us different sub-pixel rendering

IanC

2:44 AM

@Serg, look for a ModifyFont method for the labels

then use maybe "ubuntu monospace" as the font instead

and see if it works

Serg

Tried with tabs. Same effect

i don't wanna mess with fonts, don't wanna brick anything on end user side

IanC

you can use the default monospace font

instead of "ubuntu monospace" just "Monospace"

Serg

Hmmm, I'm gonna try something once i come back from smoke

i wonder if it's just my string or the indicator menu

IanC

on the image you can see the chars have a different length, so you're calculating the number of spaces right, but it ends up unaligned because the word length depends on its chars

I think your string is fine, I mean, you're setting an offset of 30 and taking away the chars from the label name

Serg

In command line everything aligns nicely !

IanC

2:55 AM

then adding the label value, I think it's just a font issue. You can try what Mateo suggested and use different size spaces, or try different numbers of spaces (which I think will result in a small offset anyways)

Serg

so it's the indicator

IanC

because command line uses monospaced fonts

Serg

3:05 AM

@IanC seems like you're right

I changed system's font via unity tweak tool

i can't find a way to change it for my indicator though

IanC

nice! I found a reference for pyGtk, there's probably a method called ModifyFont for the wrapper you're using aswell

faq.pygtk.org/index.py?file=faq04.001.htp&req=show

found a small gi.repository.gtk example here askubuntu.com/questions/181850/…

self.textview.modify_font(font_description)

seems like you can get a font_description using pango, something like Pango.font_description_from_string('Monospace')

Serg

@IanC did that, no good

seems like everything depends on the system font

IanC

tried some other font name? just for testing

Serg

yeah, "Monospace Regular"

same as what UTT gives

IanC

" Just a note, modify_font is deprecated now in favor of override_font for Gtk. – RobotHumans Jul 11 '14 at 14:00 "

don't think it's the problem but just in case

Serg

3:24 AM

Nope . . . that doesn't do it either

Actually . . . Lemme try something

extra spaces seem to be truncated

IanC

the font changed though?

Serg

I added spaces in original string, but padded with underscore

nope

font doesn't change at all

IanC

I'd guess it's something about the font_description not being returned right, not sure why

man, have to go sleep, waking up in like 5 hours haha

keep poking around and you'll probably figure what's wrong with the font method

good night @Serg!

Serg

@IanC sleep well, thanks for all the help

peace

Serg

@Seth can i haz Gtk queshtun ?

Seth

sure

Serg

So . . .I tried sort of align labels in my indicator. Only works properly if i change system font to monospace. So, is there a way to make font change just for that one indicator ?

I tried couple of ways, but all failed

Seth

I have no idea. But it seems to me you're asking the wrong question. How do you get your alignment to work fine with the default font?

I don't know, but it would be an on-topic question here or on Stack Overflow.

Kaz Wolfe

6:26 AM

@Seth @jokerdino: With the mods' blessing, I'd like to conduct a test with WolfBot in both the main room and Regulators. Ideally, I'd spawn an instance of the bot both here and in Regulators so each room can get a feel for it, and so that we can decide where it belongs. I'd hazard a guess that 48 hours is enough.

Would this be alright with everyone?

jokerdino

What is the bot doing actually?

Kaz Wolfe

right now, watching for Mint/Kali/Elementary posts, and serving bookmarks.

I'll probably add the EOL versions to the bot (not tags) before I bring the bot in.

jokerdino

I can't give my blessing.

Nathan Osman

George got kicked out for trying to be useful...

Kaz Wolfe

@NathanOsman Which is why I'm trying very hard to work with the mods, to avoid said issues.

@jokerdino Alright then. If there's anything I can do to change your mind about this, what would it be to make this work?

Nathan Osman

6:31 AM

I'm sure it boils to something like this:
1. Bot must not post unsollicited messages
2. Bot must be able to shut-up on command of a mod
3. Bot must recognize when it is being triggered too often and discourage conversation
4. Bot must like bacon

jokerdino

While I like the idea of what you are doing, I don't want it to be a bot.

Nathan Osman

@jokerdino we've got part of that Twitter web app up and running - want an account?

Kaz Wolfe

I'm looking at reliable ways to shut him up now, but mods can just stop the bot until I get a better way implemented. Over-triggers I may need help with, because I don't know how to make expiring things.

jokerdino

Sure!

Nathan Osman

@jokerdino do you have an email address I can send the username and password to?

Oh hang on.

jokerdino

6:33 AM

yes, I have many.

Nathan Osman

You're on Hangouts.

I'll send it there.

Kaz Wolfe

@jokerdino Well, how else can we report the data here? Unless you want it to be something like a website you explicitly have to visit...

jokerdino

yeah

actually, I have been liking some Trello boards.

Kaz Wolfe

so... a bot to post to trello?

jokerdino

haven't quite thought that fair.

Kaz Wolfe

6:37 AM

the thing that is kinda not making sense to me (sorry, but i just want to know) is what can I do to bring it up to an accepted point, like SmokeDetector?

jokerdino

if you can ID posts that requires community attention, that would be great.

Kaz Wolfe

well there's a platform to do that.

so it's just the question of delivering the bad posts to us

Serg

Question: are people going to be pissed if I trim down the descriptions in my indicator ? Like form "Partition" to "PART" ?

Zanna

that seems ambiguous... part could be various things?

jokerdino

Serg

NULL NULL

Sigh . . . Ubuntu Regular font hates padding in my indicator

Monospace fonts are alright but . . .

I can't change font within my indicator

The system font has to change

Or I need to shorted the descriptions

Nathan Osman

What about a tab?

'\t'

Does that work for alignment?

Serg

Nope. Tried that as well. No good

Nathan Osman

6:52 AM

:(

Serg

I've tried tabs, underscore, dot, pipe, letters- nothing works with that font

Nathan Osman

Could you put the labels on a separate line above their values and then use spaces to indent the values?

Zanna

I guess part is OK if it's sda1 or something, I can see it's a partition...

btw, people with eMMC storage like me have long partition labels. My root partition is /dev/mmcblk0p2

Serg

@NathanOsman you mean have sort of tabular form instead of a list ? like df output ?

Nathan Osman

No, I mean instead of:

LABEL: value

You do:

LABEL:
    value

You can disable the menu item so that it can't be clicked (and won't be highlighted).

Meh, I don't know. It might be easier to just use a colon and not use spaces between the two.

Serg

6:58 AM

Mmmm, I could try doing that. At this point I'm not quite sure how to approach this

This kind of works . . . but then description labels are useles

Kaz Wolfe

7:21 AM

@Serg Where's the API documentation for indicators?

Serg

@KazWolfe This: lazka.github.io/pgi-docs/index.html#AppIndicator3-0.1 There's also a few examples online : wiki.ubuntu.com/DesktopExperienceTeam/ApplicationIndicators That however only does basic stuff. The menu items come from Gtk.MenuItem and there's a way to set labels with Gtk.Label class

Kaz Wolfe

yeah, i have some example code..

@Serg What happens if you use U+000B?

Serg

For padding ? Let's see

Not a lot happens:)

Kaz Wolfe

huh.

and @Serg, idea on your issue with toggles. The bluetooth indicator uses some sort of "attribute" that I can't seem to find in PyGTK.

But you can probably workaround with an image.

Serg

Two problems here: icons get set on the left side only AND of very small size

Kaz Wolfe

7:36 AM

ah.

can't you just make this text monospace?

Serg

There are couple of methods to "override" font, but i've tried tons of variations, nothing worked. The only thing that works is changing system font to monospace

I guess there's not a lot I can do. The indicators in reality are nothing more than a simple text menu. That's all

Kaz Wolfe

yeah, the indicators seem to be really limited

unless you can write raw, it doesn't seem to be possible to add anything but simple stuff.

bug against DBUS imo

Serg

A few times I've seen a guy put bounty on how to write System Indicators, which is what Bluetooth and Sound menu seem to be

Hmmm, maybe that's the thing

Kaz Wolfe

yeah, i think you need to hook them pre-appindicator for what you want

also someone just serial-downvoted all the answers on my "what should bot do" question, but they didn't downvote or upvote the kill the bot post.

Serg

Hmmm, there's people who are, let's just say it, really lack patience

but they didn't downvote the question, which is weird.

@chaskes: The version I've got is the 3.20.2 version in my VM so I suspect that they fixed a lot in the 3.22 version which for some reason isn't in there yet.

chaskes

Plus, I can't find the exact policy right now but (as above) I suspect it also has to do with the new-ish gnome policy change for long term vs short term support for versions. I suspect the ppa might not have all the implications worked out now.

@chaskes: What exactly did they change in the policy?

edwinksl

@Zacharee1 what reason should i pick

chaskes

2:35 PM

@ParanoidPanda I don't remember the full details and I can't find the announcement. But basically some versions will be lts for 3 yrs. Others will be short term. They're no longer supporting all versions. If you're writing a gnome specific app, they suggest targeting the lts. Otherwise, they don't promise to not break your app at any moment. 3.22 is the first version to implement this, so maybe it's not related to your problem. help.gnome.org/misc/release-notes/3.22/developers.html.en
