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.

Silly volume control scripts for openbox that probably won't work for everyone

Code:
#!/bin/bash

# volume changer+notifier, using notify-send, and tested only with xfce4-notifyd
# the syntax is the same of the "end" of what you'd use in plain amixer, see "$1"
# Ex.: 5%-, 5%+, 30, 60%

com=(`amixer set "Master" $1`)

vol1=${com[20]} 

# and here's why it won't work for everybody. The output of amixer includes
# things like soundcard features, which are array elements I'm just

kwrite "vi input mode" enabled accidentaly is quite annoying

First of all, you may be used to sometimes pasting stuff with shift+control+V instead of just control+V. Perhaps that's the way it's done in nano and/or some terminal emulators. The problem is that it's now also the default shortcut to enable "vi edit mode" in kwrite.

For people who like myself, don't really get "vi", using nano or something like that when forced to use cli editors, if you're in kwrite (perhaps also kate) and all of a sudden it seems to behave...

Parsing script arguments in bash, without getopt(s)

Posted 03-12-2016 at 05:15 PM by the dsc (linux-related notes)
Tags arguments, bash

Nifty. Just found that on stackoverflow:

I originally answered the question as the OP asked. This Q/A is getting a lot of attention, so I should also offer the non-magic way to do this. I'm going to expand upon guneysus's answer to fix the nasty sed and include Tobias Kienzler's suggestion.

Opera Presto had the best GUI ever. Ever.

Posted 02-21-2016 at 10:27 PM by the dsc (linux-related notes)

I can't speak anything about the web-rendering part, which seemed at very least okay, in pair with firefox and chrome, if not somewhat better, sometimes. Even there the GUI alone could give it an edge sometimes as it had a button where you could choose to display/download no image at all, only display already cached images, or operate normally. Other browsers may even have that function, but it's hidden deeper in a less customizable GUI.

And customization was so easy and powerfull....
