Some time ago, I took a break from social media and then gave them another try. Today I deleted my account on the only generalist social medium I have consistently used. Social media have proven to be excessively powerful tools, out of the control of governments, institutions, people who use them. They have not been sufficiently regulated, have dodged rules some governments have long tried to impose on them, and have become, also thanks to their slow response and inaction, a mean of dissemination of ideas that are far from positive and constructive, as recent events have shown, not for the first time. It has been interesting to request my…

Merry Christmas and Happy 2021
It has been a difficult year for many of us: some had to face illness and some are not among us anymore, others suffered losses, and many are struggling while they try managing a situation we imagined possible but were hardly unprepared to live. In times like these, spending time with the people we love matters even more than usual. Particularly for our elderly, who are more isolated due to the restrictions imposed by the pandemic, which keep them safe but also make them feel lonelier. Call them, particularly in these days, when loneliness hits them harder. Take time to do it often and don’t rush your calls. It does…

The EU plans to fight planned obsolescence
The European Union plans to address planned obsolescence. While the resolution was voted by the EU Parliament in 2017, and the implementation is still undefined, I think this is very important move, and it is relevant for a lot of modern devices, particularly electronics, but also home appliances. Want some examples? Try to replace the battery of an electrical toothbrush or of a smartphone without causing any damage.

Bug bounty program from the EU for FOSS
The European Union is starting a bug bounty program for key Free and Open-Source Software (FOSS) used in the Union. Further details can be found here. This seems an excellent initiative to support broadly adopted free-software products, which hopefully will evolve in stable funding initiatives for relevant projects.

Contributing research work to open-source projects
As the main developer of OpenQBMM, an add-on for OpenFOAM which implements quadrature-based moment methods for the solution of generalized population balance equations, I have been recently involved in the transfer of the copyright on the OpenQBMM code base to the OpenFOAM Foundation, to be able to contribute the corresponding source code to them. I summarize here some motivations, lessons learned and some advice that may be useful to others who want to follow the same path. Why contribute? This is a question several have asked. Why contribute a code base that took four years of work to be build (and quite some nights, holiday, weekends too), including research, overcoming…
