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.

Mapping the tablet to monitor with the aid of an inkscape, plus fine-grained mouse accuracy

I'm speaking of the wacom/genius/aiptek "drawing/writing" kind of tablets, not the "big smartphone", mini-PC-embedded-with-touchscreen type, even though cintiqs and the like blur the distinction a bit.

Without a GUI to actually map the correspondence between the tablet and monitor, one method is to first create an image that is just two rectangles: one representing the full area of your tablet, and another rectangle to the proportion you want to use of the tablet...

N00b method to toggle some verbosity on command for bash scripts

Just something I came up with that is probably not how actual programmers/scripters(?) would advise, specially the parameter/flag thing which is beside the point here.

Code:
if [[ $1 == "v" ]] ; then

ver(){
echo $@
}

else

ver(){
:    # ":" is a "do nothing" command
}

fi

a=10

echo normal output

ver verbose output $a

Replace trash-cli with kioclient move $@ trash:/ for cross-partition trashing

Posted 03-27-2016 at 09:17 PM by the dsc (linux-related notes)
Tags trash

However arguable, some people want to trash by moving into another partition's trash folders. The linux/unix/whatever trash specifications theoretically prohibit that, but KDE's implementation doesn't. So a linked or bind-mounted trash into a different partition will behave normally, except it will move the file across, obviously.

If you also use trash-cli, which won't work with such hacks, it can be replaced with the kioclient command, that in turn can be scripted or perhaps even...

New file name generator script/function, to avoid overwrites w/o user input

Posted 03-27-2016 at 07:11 PM by the dsc (linux-related notes)

Usage examples:

cp/mv/ln/etc file11.txt $(newname "/some/path/file11.txt")

cp/mv/ln/etc file11.txt $(newname "/some/path/whatever.txt")


If there's a file11.txt or whatever.txt already there, it will rename automatically to file11(1).txt or whatever(1).txt, and (N+1) from then on.

The whole path/name must be between quotes because of spaces and such things.

May be dangerous and somehow make you lose files...

Apparent bug with KDE/plasma file associations

Posted 03-27-2016 at 01:22 PM by the dsc (linux-related notes)
Updated 03-29-2016 at 05:40 PM by the dsc

At least in Ubuntu wily, it doesn't seem to allow you to chose the default application to open a file type. You try to do it, but it "magically" restores the previous default association before your eyes. Even if you chanced the config file, somehow. (I'm assuming it's mimeapps.lst, but I'm not sure. It seems that it's cool nowadays to have cryptic, hidden config files, avoiding to mention them unless strictly necessary, pretending it's all magic and config files don't exist)
