@Oli :D :D :D

@Oli What version of Ubuntu are you running?

@HeatherBrown and you?

Oli

10:22 PM

@Fabby 14.04

@Oli Good man! Stable!

@Oli in a nutshell, we're trying to fix Paranoid Panda's acpi problem while throwing in *nix jokes

user139252

@Fabby At work, 14.10(they don't know what EOL means here). At home, 15.04

@HeatherBrown Where are you now???

user139252

Work.

10:23 PM

Damn!

user139252

Need me to SSH into home for something?

- Make sandwich. -What ? No, do it yourself. - sudo make sandwich. -What kind of bread ?

Thanks anyway...

@HeatherBrown Not yet...

user136984

@Fabby: cat: /etc/acpi/events/lid: No such file or directory :)

Q: Any funny *nix one-liners?

This question is left open because it was historically allowed, but it is not considered a good, on-topic question for this site and would be closed if asked today. More info: http://unix.stackexchange.com/faq I saw a t-shirt reading 'anything you say gets piped to /dev/null', not incre...

I'm just gonna leave that there

@Oli:

user136984

@HeatherBrown do you have time to SSH into 15.04 and do a:

ps -alx | grep --ignore-case acpi

user136984

@Fabby:

> asus-wireless.sh ibm-wireless.sh tosh-wireless.sh

10:26 PM

@ParanoidPanda OK...

@ParanoidPanda Could you execute the command I asked Heather to do again as well, so I don't have to scroll up?

user136984

It all worked before, so why did my lid thing suddenly stop working though?

user136984

Ok

Is that how it should look?

10:29 PM

@HeatherBrown Do you know anything about systemd?

user139252

@Fabby Enough that I disabled it because it didn't like my laptop.

if yes, can you help @ParanoidPanda change his settings so his acpi daemon starts up just like yours?

(very similar to 14.04)

user139252

Using upstart instead

RPi Awesomeness

Okay...detecting eye movements in OpenCV is not simple at all.

@HeatherBrown Ah!

back to square 1.

@ParanoidPanda So:

user136984

10:30 PM

Why has it suddenly stopped functioning though? Is it a bug?

My original hunch is right...

you've got a problem in acpi...

user136984

Yes, now what to do about it? :)

and you need to solve that...

So I've pointed you in the right direction...

Problem determination is 50% of the solution!

so now go solve it!

Oli

@RPiAwesomeness Movements might not be too hard but gaze tracking (eg "what is the user looking at?") is really hard.

@ParanoidPanda RTFM SystemD

10:32 PM

@GeorgetheDev what is my favorite color?

@Mateo I don't know.

user136984

@Fabby: Do you think that this could be a bug in ACPI causing this?

user136984

@GeorgetheDev: What is my favourite type of cute?

and get some help from someone that has SystemD installed and set it to the same as him/her/it

@GeorgetheDev hello

10:32 PM

@Serg Howdy!

@GeorgetheDev how are you ?

@ParanoidPanda Oh, and as you've got an IBM ThinkPad...

@GeorgetheDev what's the time ?

@Serg The current time is Tue, 04 Aug 2015 22:33:47 GMT.

user136984

@Fabby: Why is it not what it should be in the first place? And why did it suddenly just go wrong? Do you think that there is a bug somewhere?

10:33 PM

Find someone with 15.04 and a ThinkPad!

user136984

That might be difficult...

Advertisement could help , perhaps ?

@ParanoidPanda My hunch is you tinkering too much!

Ooo, I have an old thinkpad, back when it was still IBM

Maybe two?

@ParanoidPanda Ah! that is called "root cause analysis"

user139252

10:35 PM

It's Lenovo now. I don't like Lenovo. They bought Motorola from Google.

@ParanoidPanda and that gets done after the problem is solved!

(and that normally takes more time then actually solving the problem)

Listen to an old fart for once...

Problem determination and root cause analysis are hard...

user136984

@Fabby: Could it just be a loose wire?

@ParanoidPanda get a newer computer those are long past...

problem solving is easy!

user136984

Also, I haven't changed my machine that much, so I don't think that it is that...

10:37 PM

@ParanoidPanda It can be a micro-meteoroid strike,

a cosmic ray

a buffer underrun

But the last one I saw had a loose chip I had to solder back in place, does it rattel when you shake it?

a mini blmack hole

@Mateo :D :D :D

That's a good one!

I have to remember that!

user136984

@Mateo: It squeaks when I shake it... :D

@ParanoidPanda so you're looking much better before you asked me a question then before...

O_o that can't be a good sign

10:39 PM

I can't give you a definite answer BUT:

1/ you know how to problem solve yourself better now if you use my approach in the future

2/ you know that ACPI events don't generate keystrokes (Duh!)

3/ You know your problem lies in ACPI

the rest is up to you now!

Good enough?

user136984

Well, it has at least solved half of my problem...

user136984

@Fabby: So I thank you very much! :)

user139252

@ParanoidPanda It's my butterflies. I release a bunch of them over a local river, their flapping wings changed the ripple patterns in the water, which changed the way the light reflected off of it in such a manner that the amount of light radiation increased in your home just enough to burn out one of the wires.

@ParanoidPanda :D Just saw your edit! :P ;-)

user136984

@HeatherBrown: All the magic powers of chaos theory! :D

user136984

10:44 PM

@Fabby: :)

user136984

Does it actually ping you or something if I put @Fabby in a post?

user136984

Because I have always wondered about that...

@HeatherBrown I hope they weren't storm butterflies!!! ;-)

So get 30 random people in a room and more often than not 2 people will share the same birthday.

@ParanoidPanda No, I had the page still open in a tab and it said "an edit was made, click to reload..."

10:47 PM

@Fabby could acpi_listen help diagnose the issue ?

user136984

Right...

@Serg maybe... I'm not qualifies to solve his problem as I don't know enough about SystemD...

I'm not a god! I'm just a Vorlon!

>:)

well, i'm not qualified either, just trying to throw out ideas here

Nearly 01 AM here...

@Serg throw all you want!

(just not in my direction!)

I've tried and I know my limits!

I've only been using Linux for nearly 2 years now?

1.5 years here

actually, is there a way to find on when a system was installed ?

10:51 PM

@Serg January 2014.

user139252

time since install please computer

Q: How can I tell what date Ubuntu was installed?

80

is there a command which will output the date that ubuntu (or any distribution) was installed?

bash system-installation log

sudo dumpe2fs /dev/sda1 | grep 'Filesystem created:'
dumpe2fs 1.42.9 *(4-Feb-2014)*

(just upvoted 2nd answer)

That was when I installed 12.04

Terrance

What accepted answer?

user136984

Well, thanks guys for all the help that you have given me tonight, it has been greatly appreciated and at least I now know what is going wrong! :)

user136984

10:57 PM

@NathanOsman: I am off to bed now, but please do ping me with your penguin pics when you get time to get them. :)

user136984

Goodnight everyone! :)

@ParanoidPanda See you later.

@ParanoidPanda Another 3 minutes before you turn back into a pumpkin!

2

go to bed!

Quickly!

;-) Good night!

I'm off too!

user136984

:)

@ParanoidPanda Sigh! Another useless message of mine starred just because it was funny to ParanoidPanda :P

10:59 PM

@Fabby March 25 2014

Not even half year

oO

I was 1.75 months earlier then you!

Why did you switch?

туалет! Скоро повернусь!

@Fabby Honestly, I don't know. My classes in university weren't going that good. In fact, my standing in university is very bad. Other students seemed to be getting somewhere. In fact my cousin was running Ubuntu and kali , which 3 years ago didn't tell me anything. So I was in a kind of frustrated mood, like 'either something going to happen now, i'm going to learn something new , or fail miserably' and I guess I wanted to change my life and catch up with my cousin, become a smart guy

Before that I failed C programming class 2 times. With Ubuntu and nano and gcc passed it with blazing A, even wrote a program to read pids of processes in /proc folder as final project. Java class ? got C there, but if i didn't let my hands down on one of the homeworks, i could have easily had A there

Ah... Well, good on you!

Funniest thing is that I wrote program during exam in cygwin, and since our uni uses visual studio, i copied code over there. But Visual Studio complained about scanf ! Later i learned that Visual Studio developers for some reason stated scanf is unsafe and you have to add override option to the line above #include. Good thing my professor was cool and allowed me to use cygwin.

@Fabby and you ? what brought your attention to Ubuntu ?

:D

I didn't want to shell out money to Micro$oft for a computer that someone gave me...

11:08 PM

Hehe, one of the most common reasons :D

I got a computer where I had to choose languages when installing and neither of the installed languages was Engllish...

So I called M$

and told them I wanted an English version, that I didn't install anything and asked them where I should download it...

and they told me to call the manufacturer...

and the manufacturer told me to call M$

So I called M$ again, told them who I was and what I did and stuff, but the GM that I knew from years before had just quit the local subsidiary to go on retirement...

and no one knew who I was any more...

So I told them I was going to switch to Linux...

and they gave me a heads-up!

:D:D:D

Back at the time when the M$ Knowledge base was just starting up...

... they would credit people with the articles they wrote...

and I had quite a few good articles in there!

But then they abolished the practice and removed all names...

I had a few of their support techs that used to call me when they had a very difficult problem that they knew was unsolvable...

>:)

@Serg The good, old days!

Nathan Osman

@ParanoidPanda ^--- there you go

@NathanOsman Is that George standing on a sofa? or is that your wallpaper behind him?

@blade19899: look who's having a sleepless night!
