Enforce module load in CRUX

At the moment, my Linux (CRUX 3.5) does not load a kernel module for the my mainboard monitoring chipset. The mainboard is GigaByte GA-M68MT-S2 and the chip is Nuvoton NCT6775F. I need data from that chip for Conky or LM Sensors. To ensure it's available I've modified the /etc/rc.modules file, by adding

modprobe nct6775

Debugging of Ansible and Molecule

As I descrbided in this article additional Ansible options are passed at the end of molecule command. This can be use to increase verbosity of Ansible:
molecule converge -- -vvvv
Molecule own debug information can be printed to the standard output with *--debug** option, but it has be specify without molecule command. For example:
molecule --debug converge
Of course, both can be mixed togther:
molecule --debug converge -- -vvvv

edsn: Elite Dangerous Star Neighborhood

 Description

Virtual, for ever I was fascinating with maps of our star neighbourhood. Just like the one from European Southern Observatory website. Recently, I've enjoyed playing Elite Dangerous. I enjoy it even more, because it works perfectly fine on Linux (with Proton).  One of the great thing about Elite is freedom to roam between stars and visit, so many star neighbourhoods. 

The amount of stars is breathtaking. It's hard to visualize the ones which are close to the system you are in. So, I wrote a small Python script to get data from edsm and prepare them to be visualized with GNUplot.

Examples

Sol

Home, sweet home.

Stars in less than 15 Light Years from Sol

These are the commands to produce the SVG output after loading script and data into Gnuplot.

set term svg size 1600,1200
set view 45, 290, 1.25, 1.5
set output 'sol-r15.svg'; replot

Achenar

 I didn't know that the space around Achenar is so empty (OK. I don't have permit yet).

Stars in less than 15 Light Years from Achenar

These are the commands to produce the SVG output after loading script and data into Gnuplot.

set term svg size 1600,1200
set view 45, 275, 1.25, 1.5
set output 'achenar-r15.svg'; replot
