@A.B. script on the way, printing to the screen alright . . . Will need to figure out deletion part, but that's just sed . . . Or I might use awk . . . will see

terdon

Nah, sod it, who cares.

Seth

@terdon nope. No idea what caused those deletions.

terdon

@Seth He probably just came across the question by chance. I'm sure he was right to delete it.

Thanks for indulging my curiosity, by the way.

Seth

np

because of the new fast notifications deleting it didn't prevent me from seeing the gist of it so figured meh, do it anyway.

Hrm. I have to backport schroot from stretch to jessie.

It doesn't play nice with the 4.1 kernel that the Pi is using.

Can't backport it.

But I was still able to get it to work.

I'll go into more detail in an article I've almost finished writing.

Hi. Quick question: In Ubuntu 14.04 with Unity, when a window becomes unresponsive, it is grayed out and a dialog appears that asks me whether I want to kill the process.

How can I turn this off?

(Reason: Mathematica seems to do something weird, because e.g. moving sliders will trigger this unresponsiveness warning after a few seconds. Very annoying)

Q: How do I turn off the feature where a window grays out when it's thinking?

So in the last couple of releases of Ubuntu (forget when it started), a window will gray out if it is not responsive/thinking too hard. Maybe "gray out" isn't the best term, it just sort of gets darker. I'm not sure what the exact criterion is to set this off. For one program in particular (Math...

Ravan

@Neil Hello :)

Mateo

3:22 AM

@halirutan may be taking up too much process or something, have you tried realtime, lowlatency or no preempt kernel - or Ubuntu Studio

or what is the processor/memory on it - may just be time for a better computer

halirutan

@Mateo I believe the reason is in the way the Mathematica front-end communicates with its calculation kernel and that during the slider movement, other things really are unresponsive.

The program is more than 25 years old.

@Mateo Do I have to restart the window manager to apply the change?

Mateo

don't know, I'd say try it - then see

wow, this is really cool @halirutan mathematica.stackexchange.com/a/26281

halirutan

@Mateo hehe.. yes. Didn't want to answer in the first place but I started explaining to my wife how easy this works..

drawings needed to be made..

@Mateo OK, the compiz settings don't work for me, because I don't use compiz. I'm using "Gnome SHELL". When I do a compize --replace, I can easily turn the screen-dimming off with the solution you posted.

Mateo

hm...

halirutan

The real problem is, that not only the window is dimmed, I get a dialog asking me to kill the program. If I accidentally hit ESC, Mathematica is killed and all changes in the files are lost :-)

Happened already more then once.

Hmm, let's call it a night. Already half past 4. @Mateo thanks for the link.

Q: Gnome wants to kill Mathematica 10 during selection

Hello folks, I am wondering if I can reinstall ubuntu 14.04 on working copy of ubuntu 14.04 keeping my installed programs and data? Any guidelines would be great help. thank you all!

Seth

you can keep data if you have /home on a separate partition, but keeping programs is impossible if you really want to reinstall. If you keep programs what's left to reinstall?

Journeyman Geek

@MuhammadSajidIqbal dump out a list of installed applications, backup config files and /home ;p

A: How do I "duplicate" a server?

If all else fails, there's the old fashioned way - On Ubuntu or debian,use dpkg --get-selections to dump out a list of installed packages, and install them with dpkg --set-selections. The equivalent of this for red hat based distros is yum-debug-dump and yum-debug-restore (optionally with --insta...

Go home, Opera - you're drunk.

KGIII

Heh... I've seen similar. Disable hardware acceleration works for me when it goes bonkers like that.

Nathan Osman

I kinda thought I did, but I can check.

KGIII

That usually works for me but, well, Opera has been known to get drunk and get rowdy on me. It could well be what you're thinking. nods

There... sighs It has been a long day.

Nathan Osman

The only option I can find is "Disable accelerated 2D canvas".

I don't think the page is using WebGL :P

KGIII

One sec.

Nathan Osman

7:19 AM

(I'm filtering opera:flags BTW.)

KGIII

Use hardware acceleration when available

In plain ol' settings.

Well, advanced settings --- I think.

Nathan Osman

Ooooh.

Not in experiments :P

Silly me.

KGIII

LOL I understand. Had I not had a drunken Opera before, I probably would look there too.

Nathan Osman

...and switched off. Now we'll see if this happens again.

KGIII

From the terminal: opera-beta --disable-gpu-compositing

Or just "opera."

Nathan Osman

7:21 AM

Ah, good to know.

KGIII

Or "opera-developer" if that's the case.

Works for Chromium and Vivaldi and Chrome (I assume). Anything based on the Chromium source should obey it.

I've no idea - I haven't used it last couple days

xxx: (and the oscar goes to) fucking-coffee.sh - this one waits exactly 17 seconds (!), then opens an SSH session to our coffee-machine (we had no frikin idea the coffee machine is on the network, runs linux and has SSHD up and running) and sends some weird gibberish to it. Looks binary.

Turns out this thing starts brewing a mid-sized half-caf latte and waits another 24 (!) seconds before pouring it into a cup. The timing is exactly how long it takes to walk to the machine from the dudes desk.

This is awesome
