@Nathan: Oh cool! But you should really make it more obvious, I wouldn't have noticed it if you hadn't of pointed it out.

Nathan Osman

It's not really supposed to stand out.

hbdgaf

@NathanOsman - are you developing this as a userscript for SE or as an SE core developer feature?

Nathan Osman

@hbdgaf Actually, I had two purposes: (1) I really wanted this feature and nobody else was implementing it and (2) I wanted to see how well WebSockets perform in Go :P

As for #2, so far so good.

hbdgaf

@NathanOsman Nice. I was just asking. I hear websockets work quite well. I've seen when I was looking around, a skype clone in the browser that was built that way.

Nathan Osman

Yup, latency is minimized and so is bandwidth since there's no need for long-polling. (Almost, WebSockets do need a ping sent every 30 seconds or so.)

hbdgaf

17:08

I wonder if it actually needs the ping if there is actual traffic? That could be a problem with the spec. It shouldn't.

Serg

@ByteCommander yes, i kinda need the help - just kill me so i don't have to deal with this specifications crap anymore

Byte Commander

Just use a pipe and redirect Mr. Bullet to Mr. Head...

Nah, don't star it again! it's already on the wall by NathanOsman.

hbdgaf

I'm just saying "If traffic, reset counter. If counter exceeded, send ping." It's really simple logic.

Byte Commander

Please unstar (probably @ParanoidPanda?)

hbdgaf

Chat mods can unstar it if they want to.

Byte Commander

17:15

I am no room owner though. At least not here.

And it does not hurt, it's just superfluous.

hbdgaf

This is true. I was going to say something about starring it the first time it showed up, but again... superfluous.

Byte Commander

@NathanOsman Could you replace "User" with the actual username here?

Nathan Osman

Not easily.

Byte Commander

Because the icon is really tiny and sometimes users have the same or similar icons.

Nathan Osman

To get that data, I have to use undocumented SE functions.

And I haven't found one that works exactly the way I need.

hbdgaf

17:17

@ByteCommander That's a good FR bug.

Byte Commander

Well, is any SE chat function documented at all?

Nathan Osman

No, not really :)

Byte Commander

There you see! ;)

Nathan Osman

I'll see what I can do... that did bug me too.

Anyway, I'll be mobile for most of the rest of the day. Gotta run.

Byte Commander

Okay. Shall I add it as GitHub issue formally? Or is that not necessary?

Nathan Osman

17:18

Sure, go ahead.

Byte Commander

Will do!

user136984

@ByteCommander Oh, right, sorry... Done now. :)

Byte Commander

:)

Aaron Hall

I enjoy reading the source code of programs and figuring out how they work that way. If I wanted to figure out "Ubuntu" where would I best start?

Byte Commander

@AaronHall Linux kernel.

Don't expect that to be easy, though.

Aaron Hall

17:25

Linux kernel? For real?

Byte Commander

That's the core of Ubuntu. Or what do you want?

hbdgaf

Why not? @NathanOsman made a driver for the USB mail notifier thing.

Byte Commander

You can as well examine the Unity desktop or whatever software you want.

Aaron Hall

I dunno, I guess the kernel is as good a place as any to start...

Although if Unity works like an abstract controller sitting on top of it, maybe that would work.

hbdgaf

Just get ready for the first beating. It's going to hurt. After that though, you should be fine.

Aaron Hall

17:27

First beating?

user136984

@AaronHall: Yes, he means that the Linux kernel is violent. ;-)

hbdgaf

@AaronHall You're going to make mistakes. I'm going to make mistakes. You have to get over that hump before you're any good at anything. So, just take it and move on.

Totally not implying violence.

Aaron Hall

Fair enough. bends over, hoping the book he used for padding doesn't show

hbdgaf

LOL. Nice one.

deostroll

Oh lord, save me for I have sinned...while formatting my usb stick, I accidentally removed it...now it won't mount...

user136984

17:36

Sorry, this just reminded me of a Russian animation about two dogs, and one is explaining the clock to the other and tells him that it is just this thing that walks walks, and then goes boom! And the other dog says "So it walks and it fights?"! :D

user136984

Although I don't know if my translation was too direct for you guys to understand the joke.

user136984

@Fabby Probably will though.

hbdgaf

@ParanoidPanda I get it.

user136984

Good! :D

user136984

I thought the "walking" bit might confuse a few people as that was the very directly translated part that I had to keep intact for the joke to work, but I didn't know if that was the right way of putting it in English.

user136984

17:39

:D

hbdgaf

I don't think it is, but I think the right way of putting is is probably a lot like "You mean it fixes and it breaks?"

edward torvalds

in which files locale settings are set?

hbdgaf

Or, I don't understand the joke as well as I thought.

Byte Commander

@NathanOsman And maybe you could make the grey border around the avatar icon a bit smaller or the rounded avatar itself bigger. What do you think?

user136984

@hbdgaf: No, because when it walks the pendulum swings, when it goes boom it chimes, but the dog took this literally and thought that it walks and also hits/fights.

user136984

17:43

:D

Byte Commander

@ParanoidPanda I don't.

user136984

@ByteCommander: When it walks the pendulum swings, when it goes boom it chimes, but the dog took this literally and thought that it walks and also hits/fights.

user136984

Learn Russian, or maybe ask @Fabby for a better explanation/translation... :P

Byte Commander

/me is still not laughing... :P

hbdgaf

@ParanoidPanda Okay. So, the walking is just the waiting and the going boom is what it really sounds like. That makes sense too.

user136984

17:45

Yes, you're getting there... :D

user136984

I think that the joke is probably funnier in Russian though. :P

hbdgaf

Probably. Still a nice apocryphal story though.

Nathan Osman

Yup, kernel programming is fun.

hbdgaf

@ParanoidPanda I do get the sarcasm though. Put what I said earlier next to the sarcasm.

Byte Commander

What shall we do with askubuntu.com/q/688202/367990 ? It's half programming/reverse-engineering, half Ubuntu (phone). But it's very unlikely to get any helpful answer.

A.B.

@hg8 I'm here, yes

Byte Commander

@ParanoidPanda Really!? ;D github.com/nathan-osman/auchatstatus/issues/…

hbdgaf

@ByteCommander that used to be too localised. I don't know what it's called now.

Byte Commander

> This describes a problem that can't be reproduced that seemingly went away on its own or was only relevant to a very specific period of time. It's off-topic as it's unlikely to help future readers.

Maybe that? ^

user136984

@ByteCommander: Really seriously. :P

Byte Commander

That would make the chat look like a playground then though... :-/

hbdgaf

17:58

@ByteCommander Yes, that.

user136984

@ByteCommander: It was a joke. :P

Byte Commander

For sure.

user136984

VTC this EOL as off-topic.

Nathan Osman

@ByteCommander yeah, I can shrink the grey border.

Byte Commander

So that it would take less space away.

That would be nice.

Nathan Osman

18:04

It's something like 5 pixels now and I can shrink it to either 3 or 2. It needs at least a couple pixels though since the dots are 2 pixels taller than the Gravatars.

Byte Commander

Yeah, sounds good.

deostroll

I've got that problem ^

Byte Commander

deostroll

@deostroll Oh, you were the guy that unplugged it during the formatting.

Well, there were some questions about similar cases on the site. DId you google for that already?

deostroll

I honestly thought it was done...

Byte Commander

@deostroll When you plug it in and start gparted, does it show up there? Can you format it from there or recreate its partition table?

Nathan Osman

McDonald's has free WiFi. Now all they need are free power outlets.

deostroll

okay I will try that @ByteCommander

user136984

What does blocking someone on GitHub actually mean and do?

deostroll

18:38

@ByteCommander yep that worked...

user136984

Does it just prevent them from following you or something?

Byte Commander

deostroll

If it takes too long, any suggestions on how I can lower it?

@Serg @ByteCommander I occasionally code on paper.

If I'm out, and I think of a way to solve a problem, I'll write a quick method or script in my notebook.

user139252

@Terdon You're good with python, right?

terdon

@HeatherBrown Not in the least. I can barely write a hello world in Python. I'm a Perl geek.

Serg

@HeatherBrown what's function supposed to be doing ?

user139252

Given a number, x, I need to determine how to use weights that are powers of 3 to balance a scale.

user139252

For example, 2 would put out "L, R"

user139252

20:56

because you need to put "1" on the side with 2 already, 3 on the other

user139252

balance

user139252

Basically I need a way to return an abstract element in this pattern.

user139252

My function works fine as is, but only for numbers less than about 150000. Anything above takes way too long.

Serg

21:12

@HeatherBrown maybe you could try changing the function into a recursive function ?

just a thought

user139252

I'm trying to think of how to do so

kos

Guys, do you think this bug report is clear? Because so far I got no response (not even a comment): meta.stackexchange.com/questions/267990/…

Serg

well, it's clear , but . . . has it been reproduced by others ? Maybe it just need enough user's saying "Yeah, i noticed that too" to get attention

kos

@Serg I don't know. Probably you're right, I'll try to add more examples if I find them

Serg

@HEatherBrown are you in any way familiar with java ?

user139252

21:17

@Serg It's been a while

Serg

@HeatherBrown would it be much of a task to ask to take a peak at my java program, look through prof's comments and say what you think over-all ?

user139252

I can try. My mind is kind of currently obsessed with solving this challenge...

Glad it doesn't, really. Though even more kudos to Nathan for figuring out a way to do it.

@Fabby You sure I was the one that recommended it? I don't remember ever reading it xD

The script sends the time you start typing and the ID of the last message you've seen to the server app I wrote which then broadcasts it to other users with the script.

Seth

@terdon oops. Meant Mark (as Mateo figured out).

@NathanOsman Clever!

Does X run on tty7 or 8 on Ubuntu?

7

terdon

Thanks

Zacharee1

Why is that? It seems like such a random number

Seth

No, if we'd wanted random it would have been 9.

Zacharee1

Helpful...

@Mateo I did, and he does. I've seen it.

I don't know if he uses a doppleganger/sock now, but at one point he actually visited chat as sabdfl as far as I could tell.

@Zacharee1 Tradition. It's been on tty7 for at least the past 16 years that I can attest to. I've also seen 8 and 9 more recently. I guess there was a reason way back when.

Nathan Osman

Because by default there are 6 console TTYs.

The next number is... 7 :P
