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.

Possible workaround for dumb installs of multiple-versions of GIMP

Posted 06-23-2017 at 01:59 PM by the dsc (linux-related notes)
Updated 06-23-2017 at 02:00 PM by the dsc

Somehow I managed to install the debian stock GIMP 2.8 and compile the git 2.9. I had the impression that at some point they were both working, but after some upgrade of one and/or another, 2.8 was complaining about an improper version of libgimp.

That would probably have been prevented by doing things right, which may have included creating a debian package for 2.9, among other things. Perhaps the most important "other thing" would have been paying more attention with the...

Speeding up and reducing the quality of podcasts (saving disk space)

Posted 04-29-2017 at 10:49 PM by the dsc (linux-related notes)
Updated 09-15-2017 at 02:55 PM by the dsc

An interesting method I now realize is possible:

Code:
ffmpeg -i in-normal.mp3 -filter:a "atempo=1.4" -f wav - | lame -q 2 -v --vbr-new -V 9 -b8 -B 20 - out_speedup.mp3
A previous method I was using had sox and for some reason mpg123 or 321 I guess, to generate a "physical" temporary wav somewhere, this method use a pipe instead of an actual temporary file.

The input file isn't necessarily mp3, it can be m4a/aac at least, possibly also webm,...

Interface design principles

Posted 04-27-2017 at 06:31 PM by the dsc (linux-related notes)
Updated 07-05-2017 at 01:43 PM by the dsc (links!)

Just an organized rant that I'll expand gradually as I think of new things. I'm not an expert in this subject but I believe that if more designers adhered to some of these principles, it would reduce somewhat problems related with stress, like high blood pressure, violence in the workplace, mass shootings. Things will possibly apply for webdesign, software GUI/CLI, and some stuff even for "hardwares" of any sort. Not necessarily in order of importance.

Apparently [[ *"$a"* == $b ]] is DIFFERENT from [[ $b == *"$a"* ]]

Posted 04-25-2017 at 11:11 PM by the dsc (linux-related notes)
Updated 04-25-2017 at 11:25 PM by the dsc

a="foo/bar" ; b="foo/bar/gee" ; [[ *"$a"* == $b ]] && echo -e "\n 1 - b contains a; *a* = b \n" ; [[ $b == *"$a"* ]] && echo -e "\n 2 - b contains a ; b = *a* \n"

Code:

Warning about "slimjet", a chrome-based browser

Posted 04-22-2017 at 01:24 AM by the dsc (linux-related notes)
Updated 04-22-2017 at 01:26 AM by the dsc

It's something like chrome with some extra add-ons/minor-but-good UI tweaks, claiming improvements in speed I guess.

But, unlike (Chr)Opera, Chromium, or Vivaldi, installing it (at least with their provided .deb installer) will mess up with your install of Chrome!

It kind of replaces it, I'm not sure the extent of the mess yet.

After just taking a look at it, and trying to run chrome as usual, it will display a message, "please run slimjet with the...
