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.

Chromium/chrome adobe flash player. That was confusing

Posted 06-18-2016 at 03:47 PM by the dsc (linux-related notes)

I was trying to install flashplayer on chromium by symlinking with chrome's flashplayer, then I found out that you actually need to point out as flags something like "flashplayerpath=path" and also a version flag for some reason. Somewhere it was suggested that you could add it to a /etc/chromium-browser/default file that exists, and by deafult does nothing, but has a "CHROMIUMFLAGS" variable "set as empty".

Then I came up with a grep/sed line to get...

KDE5 manual bug fixes for Dolphin5 and ark service menus

Posted 06-02-2016 at 03:15 PM by the dsc (linux-related notes)
Updated 06-02-2016 at 03:22 PM by the dsc

As posted on this is a practical fix for the problem:
sudo ln -s /usr/share/kde4/servicetypes/konqpopupmenuplugin.desktop /usr/share/kservicetypes5/

And manually added service menu files must be loaded with the command [/b]kbuildsycoca5[/b].

Makes me wonder how that "KDE trinity", "Mate for KDE3" thing is going on.

["SOLVED"] Weird failure in bash string comparison

Posted 05-02-2016 at 02:43 AM by the dsc (linux-related notes)
Updated 05-02-2016 at 02:52 AM by the dsc

A string produced by a given command is somehow different from a string produced by "catting" a file produced by redirecting the output of the very same command. That's weird, if you ask me.

The "solution" is not to compare them both, but create a second file from the "same" redirection, and then strings from "catting" those files. Then the comparison won't always say the strings are different.

Setting asymmetric correspondence between screen and mouse "area"

Like the common acceleration feature, but asymmetric. So you can reach the ends of the screen with whatever range of motion "feels right", even if it's actually "wrong".

You basically misappropriate this spreadsheet:

Perhaps drawing two rectangles one inside the other may help...

[MYSTERY SOLVED] What does "echo ???????????????" really do?

Posted 04-20-2016 at 09:39 PM by the dsc (linux-related notes)
Updated 04-21-2016 at 06:07 PM by the dsc

It seems to alternate between listing an Nth file (somewhat obscurely related with the number of question marks) on the current folder, or giving some "history" entry, I guess.

That's weird.

22:54 **ROOT** /# echo ?
22:54 **ROOT** /# echo ??
22:54 **ROOT** /# echo ???
bin dev etc lib mnt opt run smb srv sys tmp usr var
22:55 **ROOT** /# echo ????
boot home proc root sbin
22:55 **ROOT** /# echo ?????
