@ChanHoSuh - you might try the solution posted here for that cafe you were having trouble with: askubuntu.com/questions/128794/…

the walk away, delete, and come back. evidently it works for someone

jokerdino

actually that method works for me when I try to connect to my friend's private mobile network.

Chan-Ho Suh

thanks for recalling

jokerdino

it connects at first, then creates problem. I then delete the details and reconnect again.

adempewolff

back when I used to work in user services, we had oodles of trouble with OS X saving authentication certificates/users/passwords/etc. for wireless networks

the only solution was to turn it off, delete everything, turn it on/configure all for x times until it finally worked

aking1012

i think either the raspberry pi or that other mini-computer the size of a thumb-drive would make an interesting accessory to add wireless computer to TV bridge without relying on an intel wireless TV. just a thought

jokerdino

12:10 PM

that must be painful

adempewolff

It's really hard getting past the propoganda/hero-worship/cult-status surrounding Apple products to convince people that they are pieces of junk. They always assume that it is IT's fault--that we broke it--because an Apple product could never naturally have a fault

jokerdino

uh Chan --^

aking1012

@adempewolff They never are if you pay the apple tax end to end. It's interop that's the problem.

jokerdino

howdy @fossfreedom

didn't see you slip in.

fossfreedom

... pinged ... hi-ya!

adempewolff

12:15 PM

@aking1012 I've seen itunes being buggy as hell with ipods before. I don't buy any of the myths surrounding Apple anymore. Overpriced garbage.

jokerdino

how goes the day?

Amith KK

Have we nothing to chat about?

jokerdino

yeah we don't have any memes to post around?

fossfreedom

... this is my lunch-break ... just dropping by .... looks like nothing major has happened so far today.

aking1012

@AmithKK I tried to push it towards wireless TV linux support, but it didn't work

jokerdino

12:17 PM

@fossfreedom probably.. i think you are currently doing bulk of the moderator stuff. every other mod has punted the job to you it seems.

fossfreedom

:) mods do stuff silently behind the scenes

jokerdino

and how was the vandalism flag handled?

Amith KK

BBL

fossfreedom

@jokerdino ... not me guv - must have been dealt with by Bruno.

... I dont see a vandalism flag today. Care to enlighten me?

jokerdino

hmm I was editing my older posts yesterday. I thought it triggered a flag or something because it prevented me from editing more than 5 posts.

fossfreedom

12:23 PM

... ok ... that flag... dismissed that. You were just tidying.

aking1012

Yeah, I've had that triggered before when I was deleting answers when there were other more detailed answers on old questions.

jokerdino

@fossfreedom yes I was trying to improve. Some answers I improved quite significantly and others just a couple of words, etc.

@aking1012 cleaning up answers is quite a troublesome chore.

aking1012

Shame there's no "I'm cleaning my old answers, can you turn off this limit for me for a day" feature. If you're found to be doing something silly, a roll-back all last day changes

fossfreedom

... I sometimes wish others round here take care of their answers as much as you... silently kick myself to put on to-do list

jokerdino

lol, I can't manage a meagre 150-odd answers. I can't imagine of your scale.

fossfreedom

12:29 PM

... dunno - gave up counting a long time ago!

jokerdino

You have about 1000+ answers.

fossfreedom

ouch ... really? must slow down.

aking1012

i slowed down a couple weeks ago

i think m reasonably cleaned my bottom ranked page by votes. iirc i only have about 2 pages to go

jokerdino

Most of my answer have at least a vote on them.

I try to delete answers with no votes. because they are generally not the most useful answer in the question.

On saying that, most of my answers have just a vote on them. Must improve on them.

aking1012

1+ or accepted answer 0 accounts for about 2/3 of my answers...and much more of the no votes are really old (or i don't think you should be doing this if you have to ask, so i'm intentionally vague)

jokerdino

12:37 PM

@aking1012 you have about double my answer count. Impressive.

aking1012

I don't think volume of answers is particularly impressive, but ty anyway

Ashu

2:27 PM

Can someone help me here. I want to know what package controls this

jokerdino

Welcome to the 5k rep club @Jacobjohanedwards

@Ashu Be more descriptive. Where did you get that image?

Ashu

Its the image of my home folder. Read the top few lines of this askubuntu.com/questions/136085/…

and thanks for taking interest

jokerdino

Hmm interesting. Can you look into accessibility settings?

Ashu

sure, just a sec

jokerdino

and hi @mateosalta

Ashu

2:35 PM

@jokerdino Bump! By accessibility what do you mean

jokerdino

universal access.

Ashu

@jokerdino there is nothing like universal access (or wait i dont know)

jokerdino

What DE are you using?

Ashu

@jokerdino well i dont know what DE is but im using 10.10 Ubuntu with nautilus file manager

fossfreedom

hey ... anybody got a 12.04 VM they dont mind trashing?

jokerdino

2:39 PM

ah, never mind. 10.10 is not supported and I never used it either.

@fossfreedom depends. I can test it in my main.

fossfreedom

no - I want an answer of mine testing - I dont want to break a main computer

adempewolff

@Ashu alt-f2 gnome-control-center

jokerdino

I haven't broken my computer in a while. I don't mind breaking anyway.

And it really does depend on what is the task.

adempewolff

I've got a 12.04 Xubuntu.....

Q: How can I replace LightDM with "MDM"?

Linux mint cinnamon 1.4 released with "MDM display manager".It is based on the code of GDM2.20.It provides:- Graphical configuration tools Themeability Remote, automatic and timed login Event scripting Language selection And it comes with more features than any other Display Manager currently...

jokerdino

@adempewolff No, I am one of the U+1 tester. Breaking is part of the task.

adempewolff

yeah, but there is a difference between breaking something in a testing environment and breaking your main environment

jokerdino

@adempewolff I don't do two different environments, etc.

Let's install MDM.

adempewolff

2:43 PM

@jokerdino hence why I asked if you are crazy doing your testing and day to day tasks in the same environment:P

jokerdino

It doesn't really make a difference.

I have my data stored in three other places.

adempewolff

@jokerdino I'm not just talking about data, I'm talking about time!

If you destroy your computer and have to spend half a day fixing it just to be able to report the bug...

jokerdino

@adempewolff I need something to keep myself busy. So, it doesn't matter after all.

ok, so you are going to test the MDM or what?

adempewolff

less efficient then a vm with a snapshot, destroy it, revert, confirm bug, report bug, revert, search for new bug

jokerdino

I think you can do it then. I feel like blogging.

;)

adempewolff

2:46 PM

Xubuntu doesn't use LightDM unfortunately... so I can't replace it

Ashu

so im left on my own again, well nothing worked, anyways thanks @jokerdino @adempewolff

fossfreedom

@adempewolff ... I thought 12.04 xubuntu had switched to lightdm?

jokerdino

@adempewolff you can switch to it yourself no?

adempewolff

eh... I don't think so. doesn't look like it at least. whatever it does use is buggy as hell though.

jokerdino

@foss would dpkg-configure work?

and somehow @adempewolff convinced me to get a VM.

fossfreedom

2:48 PM

for xubuntu? - yes - should work for any login manager.

adempewolff

biggest regret of recent memory was setting up this development environment with xubuntu instead of ubuntu or lubuntu

jokerdino

haha, I thought I couldn't download a ISO.

Seems like I have precise alpha ISO somewhere in my system.

Setting up a VM would take some time.

adempewolff

whoa, once again that damned vm just almost borked my system

something about Xubuntu just does not place nice inside virtual machines

fricking XP uses less resources

jokerdino

Lubuntu might have been a smarter choice.

adempewolff

Unity probably would use less resources than this mess

jokerdino

2:54 PM

I doubt so.

adempewolff

that was sarcasm. barely though

jokerdino

Unity has a lot of memory leaks.

ah, sarcasm.

Hmm I have no idea how to set up a VM from just the ISO.

adempewolff

sudo apt-get install virtualbox

jokerdino

that I have it.

adempewolff

oh well then, it should be super easy

in fact I've never installed a vm not from an iso

just find the settings for the cd-drive and you can load an iso

jokerdino

2:57 PM

wait, I don't have a CD burnt.

adempewolff

3:07 PM

virtualbox can mount an .iso file so the guest OS sees it as a real cd in the cd drive

jokerdino

so, how exactly mount that iso?

mateo_salta

hi @jokerdino , missed your earlier greeting, then got a notification

adempewolff

@fossfreedom you might want to add a section about adding (or choosing not to) add mint's public key

jokerdino

@mateo_salta hi. and it's alright

adempewolff

@jokerdino ummm, it would be hard for me to get a screenshot

jokerdino

3:10 PM

it's alright. i should be able to dig it. somehow.

adempewolff

but when the machine is running (even if it is only loading the BIOS) open the Devices menu:CD/DVD devices:Choose a virtual CD/DVD disk file...

fossfreedom

@adempewolff ... do you mean its an optional step to add the public key?

jokerdino

@adempewolff figured out with some help from Super User-ers

adempewolff

I just mean that someone following your howto would see the scary "W: GPG error: http://packages.linuxmint.com maya Release: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY 3EE67F3D0FF405B2" and "WARNING: The following packages cannot be authenticated!
linuxmint-keyring
Install these packages without verification [y/N]? y"

mateo_salta

installing mdm, sounds cool. wonder if it has default session, and loging in to a session for only that session.

fossfreedom

3:13 PM

... good point - will copy and paste the above. Thanks.

adempewolff

so it couldn't hurt to just mention that they will see these warnings and maybe have an optional step of installing the public keys

no problem

gonna reboot now and see if it works

host OS ssh tunnel is being buggy so I'm chatting from the guest OS right now... back in a jiffy... hopefully...

fossfreedom

@adempewolff see you on the other side ... :)

adempewolff

fossfreedom

that's looks like good news ... but can you login ...?

jokerdino

I have no luck setting up a virtual box. I give up.

adempewolff

3:22 PM

@fossfreedom yes. everything appears to work fine. I saw this when I was installing "The home directory `/var/lib/mdm' already exists. Not copying from `/etc/skel'.
adduser: Warning: The home directory `/var/lib/mdm' does not belong to the user you are currently creating." but it doesn't look like it was consequential

fossfreedom

... ok - agreed... message doesnt look an issue... cool ... then this works with Xubuntu ... I might try this on my main computer. There are some excellent GDM2 themes I seem to remember.

adempewolff

can verify that mdmsetup opens without problems

fossfreedom

@adempewolff excellent - @nirmik must have another issue then.

adempewolff

do you want me to test the second part of the how to, installing a new theme?

fossfreedom

If you have a few minutes - yes please!

adempewolff

3:28 PM

okay, where's the james bond theme? I want it!

@fossfreedom "(for example from this website) " your link is dead here

maybe you want this: gnome-look.org/index.php?xcontentmode=150

fossfreedom

... damn my copying and pasting ... yes gnome-look.org

adempewolff

I think you just left off the url-string to pass to /show.php

fossfreedom

change the type to "GDM theme" ... some interesting stuff there ... dont see james bond though ... ;) Tron looks good gnome-look.org/content/show.php/TRON+GATE?content=140442

adempewolff

yeah I found it, I've been looking through them

I got a kick out of "broken vista"

jokerdino

askubuntu.com/a/143128/25798 - thinks it is not an answer.

fossfreedom

3:38 PM

@jokerdino ... oops ... deleted sorry - yep agreed.

jokerdino

haha, it's ok and thanks.

adempewolff

ooo, I just noticed a bug (not related to the mdm testing) if you change the text size in accessibility settings to a smaller size then back to normal again, the desktop notifications text is still small

jokerdino

@adempewolff yeah, you need to restart that to fix it.

you might want to file a bug.

adempewolff

@fossfreedom none of these download links are working to download the gdm themes

could be China though

fossfreedom

... the tron theme file download looks ok ... if you are in china maybe the "great firewall" is blocking gnome-look files ?

adempewolff

3:42 PM

they are very subversive, gdm themes

fossfreedom

I'm interested in your feedback here, fellow G+ers: plus.google.com/102166658324404686982/posts/4SKo4zXdkhM

@rlemon that was quick, I'm guessing you were already typing?

rlemon

lol i'm in the JS room as well.

and the PHP room

"strict" limits are a waste of time... just like 20 line functions...

25 line function... no problem... 90 char line... no problem... 200 line function... problem... 160 char line.... problem.

Greg

Your view seems to be the most logical, but I have to say I'm strict

rlemon

my console (on all of my pc's) show more than 80 cols wide.... this is a problem of yester-year

Greg

@rlemon I agree, but I've found that by consciously editing my code to fit to the tight constraints makes me re-consider what it's doing... like a kind of quick on-the-fly refactoring.

rlemon

4:38 PM

however readability does count... but because line wrapping is no longer the main concern... a few extra chars probably wont even be noticed by the reader.

@Greg yea, a "few second optimization" after each block should be done

then testing / regression testing should help you trim the fat.

personal opinion. I don't think anyone who is "strict" minds so much seeing the 90 char lines, or the 30 line functions... it's the people who have no regards to readability that should irk you :P

Java offends me as well.

or for the word penis? because last I checked it was just another body part... like hand, or eyeball.

Amith KK

5:09 PM

Yeah

rlemon

now had i used a slang alternative for the body part... I can see how some may get offended.

like Dick can be offensive (When not talking to or about a Richard)

Pussy can be offensive (when not talking about a female feline)

in context they are fine....

same with wench... i am bringing that one back.

shoot. cat

i was thinking bitch and female dog.

wench/wenCH/
Noun:
A girl or young woman.
Synonyms:
girl - maid - lass - maiden - lassie

Wench does not mean bad things.... young women are wenches

young men are masters

Amith KK

Wench was that tool right?

old women are hags.

winch is a tool

@Tom that's more or less what you're seeing, right?

@jrg no, I am getting AUDIT

There are more log lines in my question

Although I did get one ALLOW too

jrg

oh, ok

i'm seeing it

if you change it to low

then you don't get those

Tom

@jrg right, but what else won't I get then?

jrg

you don't get AUDIT or ALLOW

i think you get DENY though

Tom

5:33 PM

Any documentation that confirms that?

jrg

(Or rather, BLOCK)

i'm looking at the manpage right now

Tom

I've looked at it too

adempewolff

low logs all blocked packets not matching the default policy (with
rate limiting), as well as packets matching logged rules

medium log level low, plus all allowed packets not matching the default
policy, all INVALID packets, and all new connections. All log‐
ging is done with rate limiting.

I think that audit is for new connections....

soo....

jrg

Looks like low is probably what you're looking for

Tom

Well, I am blocking on default. This means I never hear about BLOCK ?

aye, it does not answer what the purpose of AUDIT is though

the purpose of AUDIT (from what I'm guessing) is related to the more advanced, non-default logging

Its probably the message it gives while analyzing the packets @jrg

and to keep this working in the crontab I need to setup my ssh keys on both computers?

Hmmm... I'm afraid I've never used rsync.
