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.

Rar extraction via pcmanfm context menu apparently requires file-roller on Debian

Posted 05-20-2014 at 12:09 PM by the dsc (linux-related notes)
Tags debian, pcmanfm, rar

The title pretty much describes all that's to say about it.

Reading other forum I was left with the impression that xarchiver + unrar would suffice, but apparently it doesn't, at least in Debian Testing, May 2014.

The "DE" environment variable affects xdg-open settings/behavior

Posted 05-16-2014 at 06:32 PM by the dsc (linux-related notes)

I once saw someone who had "export DE=openbox", and so I changed accordingly, it was "kde" before, even though I'm on Openbox.

But now I realize that it affects things like xdg-open, which is set by configurations that I think aim to set almost-universal file associations. I think that perhaps Openbox "doesn't even count" as a DE to the related settings, so the result is that, for example, you can't open some stuff with the associated app from google...

Possible bug with Debian's Konqueror/Dolphin/KDE and zip extraction, and how to fix

I noticed that there was no longer the "extract" context submenu for zip files after one of the last updates. Then I went to check the ".desktop" files on /usr/share/kde4, and noticed that they had an editing mistake in the mimetype line:

MimeType= ... application/x-lzma-compressed-tar;application/zipapplication/x-deb; ...
I guess it was probably something related with deb packages, which must have edited this line and "forgot" to add the...

More than two-and-a-half-fold decrease in ~/.thumbnails disk usage with pngnq

The shared thumbnail folder can be quite sizeable on linux (or whatever OSs follow the specifications), you won't have much trouble finding forum threads of people asking if it's OK to delete it, because it's occupying too much space.

One of the reasons it occupies so much space is because the thumbnails are set to be PNG files, which are comparatively large by nature. Thumbnails for a folder full of JPEGs of moderately medium-large resolution (about 800-1200x800-1200)...

Script to quickly set the wake-alarm power on

I think it's working. Issuing "set-alarm 6:00" will set the computer to automatically turn on the next day at 6am, or the same day, if the script was executed after midnight already.

Information about the whole thing, read before trying anything, no warranties/responsibilities whatsoever and all that, actually by having some trouble with the script you warrant ME the legal rights to sue YOU for a billion dollars and/or have you as my free butler for life:
