@kos sorry =)

A: Command equivalents of Unity keyboard shortcuts

You can do it using xdotool. To install the tool, run this command in a terminal: sudo apt-get install xdotool Then you can start a test in a terminal: xdotool key Ctrl+Alt+<keypad_number>

:P ;)

I don't like "command line"

kos

@A.B. I won't give up I'm telling you :)

@A.B. Please leave it like that, that's how I find it more clear

@A.B. I format commands like that so that one immediately recognize them as such

user136984

How do you report a bug with apport again?

user136984

What command is it?

user136984

Wait...

user136984

Never mind...

6:53 PM

@kos sorry :)

@kos I was just a little cocky.

Nathan Osman

Docker really doesn't play nice with multiple base images.

Q: install windows8 over ubuntu.

I have at the moment ubuntu 15.04. I want to remove it and install windows 8. I copied windows 8 iso file into USB Stick and inserted into laptop and put USB STICK to the first place in boot list. and restarted the laptop, it is coming what am I doing wrong?

@A.B. No problem, the last line was really unuseful and you did the right thing by removing it to not unusefully clutter the post

@A.B. Sometimes I'm a little obsessive in using the same exact pattern for my posts

terdon

Personally, I avoid using < and > since, if copy/pasted, they can have very unfortunate effects. Italicizing command names makes no sense though, especially when the same command is in backticks on the next line.

Seth

Italics is for English, not code.

How many hours does an upgrade take if you are upgrading 14.10 to 15.04? Would it take an hour? Or more?

Rinzwind

@Toroidal impossible to answer. it depends largely on your hardware and internet connection

and the server used for the upgrade

user136984

So how would I be able to tell? Would I just have to do it and see?

Rinzwind

basically yes. on my machine the last update van 700Mb and took 9 minutes

user136984

Van?

user136984

Where?

user136984

7:42 PM

A white van?

user136984

:D :P

user136984

7:55 PM

Oh, you mean ran...?

user136984

Or does it stand for something...?

user136984

@Rinzwind VAN? Vanilla Apple Nice?

user136984

What exactly is prelink?

user136984

7:59 PM

I just installed it...

user136984

And have no idea what it is other than it speeds something up!

user136984

And I only got it because rkhunter nagged me about it... :D :P

Fabby

@Tim Like the Italian Company that made Generators:

PowerGenItalia.com

@Toroidal No clue, but when you find out, let me know...

;-)

kos

@Fabby Are you Italian by any chance?

user136984

@Fabby:

Most programs require libraries to function. Libraries can be integrated into a program once, by a linker, when it is compiled (static linking) or they can be integrated when the program is run by a loader, (dynamic linking).

user136984

Dynamic linking has advantages in code size and management, but every time a program is run, the loader needs to find the relevant libraries. Because the libraries can move around in memory, this causes a performance penalty, and the more libraries that need to be resolved, the greater the penalty.

user136984

Prelink reduces this penalty by using the system's dynamic linker to reversibly perform this linking in advance ("prelinking" the executable file) by relocating. Afterward, the program only needs to spend time finding the relevant libraries on being run if, for some reason (perhaps an upgrade), the libraries have changed since being prelinked.

user136984

Source

user136984

That is about prelink.

user136984

So it's probably rather a useful thing to have for the sake of performance...

8:07 PM

@kos Half Italian...

@Toroidal Looks cool! :-)

reading the original...

kos

@terdon Yes I agree, I should probably start formatting differently. I always check commands before using them, but I agree that it's easy to make people mess something up

@Fabby The reference to powergenitalia.com was suspicious in fact :) full Italian here

@kos It was about 15 years ago. They went out of business in the mean time...

@kos I should tell you some time about my stay in Milan a few years back...

Not today though... ;-)

@NathanOsman: how's Vivid? What do you use on your production system?

kos

@Fabby Sure, I'll be happy to hear :)

Nathan Osman

8:39 PM

@Fabby: by production, do you mean servers?

If so, I'm still using Trusty.

I'll be upgrading my desktop to Vivid soon enough.

anyone used an mp3 player you can listen to under water?

Seth

nope.. But I think Speedo makes one.

hbdgaf

thanks, but i'm looking for first person use cases.
