Just annotations of little "how to's", so I know I can find how to do something I've already done when I need to do it again, in case I don't remember anymore, which is not unlikely. Hopefully they can be useful to others, but I can't guarantee that it will work, or that it won't even make things worse.

Ambiance-blue seems to be a another GTK "mandatory alternative" theme for firefox

Firefox lately hasn't been working quite properly with any other theme than Adwaita, GTK3's default. Even Debian's firefox (now firefox again), even though it's still GTK2, somehow, apparently.

The main (perhaps only) problem is that "tooltips" will be black on black, both UI tooltips and alo the "native" tooltip when you hover a link.

If one doesn't hate Adwaita more than one hates not having legible tooltips, then firefox can be run as

A few tools to manage the CPU load of processes

Posted 10-12-2016 at 12:11 PM by the dsc (linux-related notes)

Sometimes I see questions related with that floating around, so here's a quick and lazy (just copying defitions from the manuals or sites of these programs) post on which hopefully someone in need of such tools will stumble as well.

KDE/QT dialogs in GTK/Gnome, or, "that's a good question".

Well now Qt uses GTK dialogs in GNOME. Why can’t Gtk “repay the debt” and use KDE dialogs in KDE?

http://blog.qt.io/blog/2008/10/01/na...logs-in-gnome/
I didn't even know that KDE did that/allowed to do that (alongside with GTK2 theming, which again, doesn't work in the other direction).

How nice would it be if it was reciprocal.

I simply don't understand some UI developers philosophies. Like "lets...

Silent pulse audio output detection/indication, with bash + arecord

Posted 10-02-2016 at 03:16 AM by the dsc (linux-related notes)

You can "grep" something at /proc or whatever that tells whether there's some sound theoretically being played, but it will give a false positive when "silent sound" is being played.

A clumsy hack along these lines can detect "silent audio" as silence:

Code:
while true ; do 
arecord -d 1 -D pulse > /dev/shm/test-audio 2>&1 
cut -c 300- /dev/shm/test-audio | grep -a [[:alpha:]] > /dev/null && echo sound

Bash xdotool+wmctrl "daemon" that maximizes "almost maximized" windows

Posted 10-01-2016 at 07:16 PM by the dsc (linux-related notes)

Tags openbox, wmctrl

I find annoying that, for whatever reason, it seems that some windows get "almost maximized" (I have the impression that some browsers do that by "design", even though I'm not sure), and then I end up clicking in a desktop pixel instead of the scroll bar or something. In my case that action is assigned to show the desktop/minimize all windows.

So here's what I just came up with so far, for a 1280x1024 resolution:

Code:
while true ; do sleep 3
