Anyone has used rhythmbox-client before?

Stefano Palazzo

@KaustubhP what to you want to know about it?

Kaustubh P

@StefanoPalazzo hey :) I have a rhythmbox instance on 192.168.1.4, and I am trying to accesss it from my PC by executing the command rhythmbox-client 192.168.1.4

I get a

(rhythmbox-client:8380): Rhythmbox-WARNING **: Did not receive a reply. Possible causes include: the remote application did not send a reply, the message bus security policy blocked the reply, the reply timeout expired, or the network connection was broken.

message

both machines have ssh-servers installed, an I also started te iBus, assuming that thats the bus the message talks about

Also tried running a rhythmbox-client on 192.168.1.4 (jukebox), but i guess that wotn work, cuz one of them has to be a master :?

Stefano Palazzo

phew sorry, I've never used it over a network

Kaustubh P

how was your setup?

Stefano Palazzo

Ibus is an input method program, that's got nothing to do with it. The message bus it talks about is presumably dbus

@KaustubhP you are not "root" when you enter this command, right?

Kaustubh P

10:21

nope

should I be?

Stefano Palazzo

no

I've read someone had the same problem, caused by him being root

Sorry, I can't help you. You should Ask a question (I'm sure it's useful for many others)

Kaustubh P

@StefanoPalazzo ohk, that helped too :)

@StefanoPalazzo about mark's comment: i believe there were plans to make a 2d version of unity.

or better: if mark says it's coming, then there are plans to make a 2d version of unity. :D

Stefano Palazzo

sounds like it, doesn't it

how cool would that be :)

and it was announced as a comment on one of my answers lol :P

do you know where that PPA is?

htorque

no idea sorry

also, see here:

A: Does Natty's Unity require proprietary graphics card drivers?

I believe Unity requires 3D graphics. So if there is an open driver that can do that, you don't require proprietary drivers. Looking a the status of the FLOSS nouveau drivers, currently you probably would need the proprietary drivers for NVIDIA, however, they are working on the necessary featur...

"In addition, there will be a 2D implementation of Unity, available in 11.04 as an option." - i guess that's clear enough :P

Stefano Palazzo

10:31

Mh.. the link is dead

Great news anyway :-)

htorque

i guess it's all super-secret :P

Stefano Palazzo

I can tell (:

htorque

my system is really broken. uninstalling language-selector removes ubuntu-desktop on a "healthy" system but doesn't on this one (with ubuntu-desktop installed)... so i ordered a SSD, cause if i'm going to do a reinstall, it better be worth it :D

i'm also thinking of switchting to x64, but i'm not yet sure

Stefano Palazzo

good for you, I did that last month and It's fantastic

(the ssd, not 64 bit)

htorque

i already used a ssd-based system and it's just awesome. :-)

apart from the speedup i'll also appreciate the silence... yesterday i was wondering why my notebook's fan is always running. turns out the fan was off and it was the 7200rpm hdd that made all the noise :D

Stefano Palazzo

10:39

Indeed, it's also much cooler at the surface

I wonder who ever thought it was a good idea to have a piece of metal spinning seven thousand times a minute in a laptop

htorque

or having such fragile moving parts in a mobile computer ;-)

Stefano Palazzo

that last thing that needs to go is the fan

My last two laptops had to be replaced because of it.

htorque

:-(

mine didn't fail but became a lot louder

Stefano Palazzo

It's a bleeding piece of plastic, costs maybe 50 cents to make

@htorque that's how it starts, it'll get louder and louder, and eventually it will turn over a bit slower, until it stops spinning altogether.

badp

It's really a fancy wheel of fortune.

Stefano Palazzo

10:45

I clean mine with a brush now, about once a month

badp

If it ends in cylinder 1337 you win!

Stefano Palazzo

:)

htorque

lol. i would even pay extra 10€ to get a high-quality, all-silent fan! but what matters to manufacturers is cutting costs... lead-free soldering is another big fail (for customers).

Stefano Palazzo

@badp you're big at gaming.se aren't you?

badp

@StefanoPalazzo It's been my main Area51 commitment :)

Stefano Palazzo

10:47

I sent a friend off to look at the VVVVV demo

badp

Beautiful game. At least, the demo is.

Stefano Palazzo

and it didn't work for him (flash works fine, but it was just a black screen)

that was on windows 7 with opera, any idea what that could've been?

htorque

opera :D

badp

in The Tavern (General) on Meta Stack Overflow Chat, Oct 9 '10 at 8:28, by Jeff Atwood

f**k Opera

Stefano Palazzo

Love the music in that game (:

@badp hehe

badp

10:48

just kidding, Opera is fine; it's probably the site that messed up somewhere

htorque

i love opera, but it certainly has issues with such content

badp

eh, at least on Linux z-order with everything flash is messed up

htorque

also, a lot of web developers only know windows, ie, and ff.

Stefano Palazzo

makes sense

htorque

i've seen js like 'if (useragent doesn't contain windows) abort;'

badp

10:51

As the MSO meme goes:

Ubuntu: Unsupported.

yay for X running at 70% CPU

htorque

any ideas how to compactly represent a 81-bit array? right now i pad it with zeros to 85 bits, then convert every 5 bits to a base-32 character, resulting in 17 characters.

Stefano Palazzo

Do you want to store it in ram?

htorque

on-disk

maybe i just should do bzip2...

Stefano Palazzo

phew

bzip2 won't be efficient for 81 bits

htorque

11:07

hm, especially run-length encoding is a waste... about 1/3 of the bits are set, maybe i can find something for sparse matrices.

Stefano Palazzo

You could do some run-length encoding

htorque

heh

Stefano Palazzo

hehe

htorque

yeah, not a lot of runs unfortunately

Stefano Palazzo

what does the array look like if you convert it to only "A-z"?

Kaustubh P

11:08

@htorque sorry to interrupt, but is the array some progression?

htorque

@StefanoPalazzo it's only 0-9a-v... of course i could raise the base a bit, just was wondering if there are better approaches

@KaustubhP nope

Stefano Palazzo

You can convert it to anything you like, say anything that fits into one byte, but leaving a few bytes for your run-length indicators, if your runs are on average ≩ 2.0, you'll save space. Say your runs are on average 3.0, then you'll save |S| / 3 / 3, so nine bits - or something like that

htorque

hm, yeah... i'd probably need to do some analysis on the input first. haven't given it a lot of thought yet. :)

Stefano Palazzo

you could make it a big integer and calculate the prime factors :-)

thats the king of time-memory trade-offs

htorque

:D

Stefano Palazzo

11:17

patft.uspto.gov/netacgi/…

interesting patent on the subject

htorque

hmmmm, let's say i want to save 100.000 of those 81-bit arrays, then i could sort them and only represent the differences... like what @KaustubhP was suggesting.

Stefano Palazzo

yeah, but calculating the differences is very hard indeed

iirc, you'd have to do a largest common substring on every one of them

htorque

wasn't that stuff related to suffix arrays/suffix trees?

looooong time ago i read about it :D

Stefano Palazzo

I'm not sure if the editing distance won't be on the same order as the length of the array itself, so you would've gained nothing by doing a diff

By the way, the complexity in the image above is, in practice, wrong. I've implemented "diff" and it was too slow to be useful, but as soon as I cached the results of the LCS function, it was really fast.

htorque

another question for the python pros: aren't there data structures to represent bijections? using two dicts seems so wrong...

Stefano Palazzo

11:33

two?

you're right, there isn't a data type in python that does them

htorque

well, one for the mapping A->B and one for the other way round. i could add a : b and b : a, but that would screw with getkeys or whatever it is called.

Stefano Palazzo

I'm just trying to implement one

htorque

ok, thanks, that was what i wanted to know :)

Stefano Palazzo

pretty interesting problem

htorque

whew, another 300 dead birds have fallen from the sky in the usa (alabama).

the end is near!

Kaustubh P

11:43

@htorque seriously?

Stefano Palazzo

@htorque pypi.python.org/pypi/blist this has a sortedset type

htorque

well, no... i'm not sure if the end is near :D

Kaustubh P

no, i meant, the brids falling from the sky :(

htorque

@StefanoPalazzo cool, thanks :-)

Stefano Palazzo

so you could define f(x) = S2[x] where S1[x] = x

htorque

11:45

htorque

the media doesn't believe in science!

Stefano Palazzo

19^ "Birds Falling From the Sky Not Unusual". 6 January 2011.

they only believe in TRPs

Imagine, if the US geological services listed 90 mass animal deaths, how many more must there be around the planet

And even so, this: "On December 30th, three young whooping cranes were found dead in Kentucky, USA" is news, apparently...

Kaustubh P

@StefanoPalazzo whats 2d and 3d mean? I am thinking something invloving goggles :S

htorque

that's certainly not unity 2d oO

as the comments suggest, it looks exactly like 10.10's unity

Stefano Palazzo

the 3d version of unity uses the graphics cards 3d rendering to paint the screen, this way you can do nice visual effects; blur, transparency, fading windows and so on. the 2d version merely paints pixels on a flat plane

so they're not talking about three dimensional space, but about the graphics card's "3d acceleration"

omgubuntu.co.uk/2011/01/…

no link to askubuntu on that one

oh damn, i give up :D

Kaustubh P

@htorque what were u attempting :P

hey, whats wrong with this command: mkdir foo_`date `

Marco Ceppi

@htorque You can't have formatting or things surrounding your messages

@KaustubhP Everything :P

mkdir foo_$(date) IIRC

Kaustubh P

it creates a directory for each part of the day

Marco Ceppi

Well, it should be mkdir "foo_$(date)" but yeah, use the $()` wrapper to execute things in an embedded fashion in bash

Kaustubh P

yeah, works :P

Marco Ceppi

14:38

But you should probably use a different format since Fri Jan 14 09:37:18 ESTY 2011 isn't the best for a file name

Kaustubh P

yeah, i was gonna say that

mkdir "foo_$(date +%Y-%b-%d)"

Marco Ceppi

I usually use date +%Y%m%d so something like $(date +%Y%m%d)_filenmame

but only because I like YYYYMMDD as my formats :)

Stefano Palazzo

date -Ru :-)

Marco Ceppi

date: illegal option -- R

Stefano Palazzo

huh

      -R, --rfc-2822            output date and time in RFC 2822 format.

Marco Ceppi

Well, actually - in release cycles this would be the equivalent of 10.04

@KaustubhP I'm sure it did. I'm on a mac at work unfortunately.

Q: Windows not closing

After login, a number of windows such as Desktop, Downloads, and Pictures opens automatically. When I try to close them one by one closes itself but last one opens all indicating starting file manager in lower panel/status bar

Q: How to close multiple nautilus folders that are opening automatically after login?

Hi community, Every time after I login into Ubuntu 5 folders from the same path (/usr/share/applications) are opening automatically I searched in Nautilus Help and I couldn’t find anything related to my issue. How to close multiple nautilus folders that are opening automatically after login?

nautilus folder

Marco Ceppi

Looks like it actually

I would comment and put the vote on it

Stefano Palazzo

"When I try to close them one by one closes itself but last one opens all "
that might mean "when I try to close them one by one, they open again as soon as I close the last one"

Marco Ceppi

15:10

True

htorque

\o/ finally we got a grip for easier window resizing:

hehe, it's also on both panels in the gnome-session :D

Roland Taylor

the end of gnome 2.x is a signal for a new desktop environment for DESKTOPS and LAPTOPS -_-

unity and shell are for netbooks and tablets, not desktops and laptops

Marco Ceppi

@RolandTaylor Do you really think that desktops and laptops are going to be around 5-8 years from now?

Roland Taylor

in a different form factor, but yes

Marco Ceppi

Most of my laptops are now stacked and clustered into mini servers

Roland Taylor

15:14

do we have flying cars?

Marco Ceppi

@RolandTaylor yeah, that form factor is tablets and netbooks

Stefano Palazzo

I bet laptops will be around for 15 years at least

Roland Taylor

I mean - everyday, practical, commonly used, widely available flying cars?

Stefano Palazzo

non-touch ones

htorque

why do you think that? i've been using unity for over half a year only on desktops and notebooks w/o a problem

Marco Ceppi

15:15

No, but we do have Tablets and Netbooks

Roland Taylor

@StefanoPalazzo +1

netbooks are not good for people like me in the real world

I'm over 6ft and my hands aren't that tiny

and tablets are not good for sitting and writing a novel

htorque

13" convertible is great

Roland Taylor

desktops are still going to be around for a while too - becoming home servers of a kind

Marco Ceppi

My hands are short, stubby, and fat netbooks are cumbersome but work

Roland Taylor

@htorque not for me

@MarcoCeppi not for me

my laptop is 17inches and I feel like complaining sometimes :P

Stefano Palazzo

15:17

We're still using a lot of technology that is completely outdated and ridiculous. Like keyboards, calculators, watches, CDs, wired telephones, ...

Roland Taylor

ofc the screen is broken - but when I replace it I'm getting something of a similar size

@StefanoPalazzo +1

htorque

there's not much difference between 14-17" notebook keyboards (size-per-key-wise)

Roland Taylor

actually that's not the only reason I like 17" laptops

I get an integrated number pad, and a comfortable layout otherwise

Marco Ceppi

To each there own.

Roland Taylor

and imagine - 2 hard drive slots :D, a tv tuner, powerful graphics - etc...

Marco Ceppi

15:19

Gnome Shell and Unity aren't going to wipe out the desktop interface as we know it

Roland Taylor

and let's not forget - when the females see it they go "shiny................."

@MarcoCeppi maybe not unity, but shell sucks

Stefano Palazzo

I want a 13.3" laptop with 3840x2400 pixels of display resolution (surely that's possible)

htorque

@MarcoCeppi oh no, that phrase was used by the nazis! consider yourself lucky not having said it in the german public. :D

Roland Taylor

Marco Ceppi

This conversation has devolved to Nazi's so quickly?

Roland Taylor

how about debian?

Stefano Palazzo

fedora will ship gnome-shell, by default

Marco Ceppi

Debian might have Unity shipping next release

Roland Taylor

debian... who knows

@StefanoPalazzo better

Stefano Palazzo

there was a big argument in the fedora community about the wallpaper

they wanted to ship the gnome-shell default wallpaper for branding reasons, and the art team was left with nothing to do, they were a bit mad about it

Marco Ceppi

Someone's filed an ITP for Unity on Debian. Let's light this candle. :)

@StefanoPalazzo a bit? do they have no courage?

fedora has had some of the best art ever!

I'd use it if they stopped marching to the arrogant army's drum

Stefano Palazzo

15:28

they did have some great wallpapers

htorque

i like it that they enable nouveau's expiremental 3d support by default (even if this can backfire terribly)

Roland Taylor

I like that too ^^

wishful thinking gets me no where :(
