LinuxQuestions.org - linux-related notes

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.

Rarely a website butchered its own interface so bad as Yahoo did to yahoogroups

You barely can search within a given group you're subscribed to -- better luck searching from google search with "site:groups.yahoo" and things like that.

Congratulations, yahoo, now hackers/defacers don't have anything to do there.

It's an old, massive transformation of a previously functional UI into a useless, unintuitive, clump of "featured bugs". I thought it would be fixed eventually, but it's just as bad as the first time they've ruined it....

OpenRC+sysv fixes Debian's (my Debian's) shutdown/reboot problem

Posted 07-02-2017 at 11:50 AM by the dsc (linux-related notes)

For some reason it was failing to unmount everything, and then simply halting indefinitely.

OpenRC/sysv seems to work fine, so far.

A console install is probably advised, if anyone is considering doing the same. After installing openrc, the install script will suggest a kind of pre-reboot line that will "manually" deactivate the services and then you should reboot. Which I did with sysreq, even though I probably shouldn't have.

I think they...

Hurdles of a customizer

Posted 06-30-2017 at 04:42 PM by the dsc (linux-related notes)

So I've recently learned that Slim Display Manager is obsolete and ideally should be replaced with something else. Perhaps that's why systemd doesn't always actually turn off the power or reboots when it should, I thought, as I've read that it wasn't keeping up to date with systemd's stuff.

I've spent almost "the entire day" testing some other ones, and somehow none works just right. They mess with environment variables so that either the notification daemon doesn't work...

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)

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,...
