In my first article I have demonstrated the gnuplotwindow.sh script and other utilities to feed the gnuplot with live data streams. Shown scripts are easy to use and if combined together they build powerful chains of data filters. The only problem with the script is that it can only display a continuous data stream updating the plot with each new incoming data sample. To display even more complex data like scatter or 3D plots a different approach of data feeding is needed. It would be necessary to update the plot blockwise and input data should also be fed in blocks. This new concept didn't match well with the gnuplotwindow.sh script so I have written a new script because mixing both concepts in one script would make it unnecessary complex and unmaintainable.

As we know Ubuntu has switched to the new "shiny" init system called systemd since the release 15.04. But the integration of that new init system isn't yet completely finished because some things aren't working as before the switch. Power management that utilized pm-utils previously is completely broken for example and no alternative solution is offered. In this article I'll explain how to restore pm-utils's old behaviour as a temporary workaround that can be used until a new and of course better official solution will be implemented.

Since around a year or two I've been using i3 tiling window manager together with the xfce4 services as my desktop environment and I'm quite content with the result. The i3-wm can be installed on top of the xfce4 DE without any package conflicts. Such a combination allows to have both DE at the same time and share common settings and applications between them.
I can't remember exactly why I have chosen the i3-wm as my window manager but maybe it's because I have read that i3-wm has vim style movement keyboard shortcuts. As far as I'm a vim user I decided to 'take it for a spin'.

volnoti or pa-applet. Without a dedicated daemon it is also pretty much simple to handle sound volume keys by a simple bash script which is bind to specific keyboard combinations.

I have performed a clean install of the newest Xubuntu distribution and I like the result. They have reacted to the bug reports I posted and fixed dependencies to the bloatware and spying packages that were not possible to avoid during Xubuntu 13.04 installation. I have also spent some time trying to figure out the minimum set of packages for the network-manager to work. Here's the installation procedure:

One new feature planned for the Xubuntu 13.10 release is the multi-monitor support integrated into XFCE desktop. Previously one would have to use xrandr to adjust monitors settings and now it should also be possible with the updated Display Settings dialog. But it is also possible to use this feature in Xubuntu 13.04
