A while ago I wrote about the Configuration of wireguard as a personal VPN solution. Now, after using that setup for four month as a standard it is time to look back and summarize my personal findings.

So I started to play around with the idea of a private VPN solution a while ago… The idea was to have a better sense of privacy when roaming between different networks. Having collected little experience with existing solutions, just using some commercial applications for business use over the last decades, I invested into a bit of research first. To identify the solution that suits my personal needs best.

I was looking for a simple solution, simple in the sense of an easy and transparent setup, also easy to use in daily life. So a robust solution. The target was to have all network traffic of my mobile devices routed through a personal system by means of a VPN tunnel. If possible, network performance should not be impacted such that it prevented me from using the solution.

Over the last decades the development of computer science has been tumbling along with unbelievable speed, unrivaled by other fields of engineering or science. New fields popping up every few weeks, a break though in complexity published every month, new paradigms and methodologies that are sometimes outdated faster than they spread…

Some of the constant drivers of that process of changes are unexpected at first glance: bionic and intelligence understanding, natural language research, medicine, … Unexpected in the sense that people working in a field as dominated by technology as computer science surprisingly often look at fields being tied to natural systems and their observance. But is that really surprising? Not at all: a good engineer will always keep an open eye for solutions found elsewhere. Proven strategies which might be worth to adapt or mimic. And natural processes, nature itself, certainly is a never ending source of unbelievable genius, precision and perfection. So actually not borrowing from there would be a highly unexpected behavior.

However intriguing and fascinating such influences for computer science are, today I want to introduce a thought about something similar but altogether different…

As some of you might know I like to offer help to fellow Softwerkers around the world from time to time. I see that as a great opportunity to combine and enjoy several positive aspects: offering help and experience, community building, an opportunity to peek over the own horizon by getting to know others, a geeky hobby and last but not least simply practicing my coding skills…

Today I came upon a question about the creation of nested structures, one of the great riddles that probably only geeks experience as “interesting”. Although I doubt that the desired data architecture chosen by the original questioner is a good one I accepted the challenge and implemented a small demonstration of a reference based approach to building such a structure.

After having started experimenting with my new electronic percussion kit I quickly started musing about situations where I could participate in jams and sessions. Since besides the social aspect that obviously is the best way to learn and make progress! Pretty soon one of the major drawbacks of an electronic drum or percussion device got obvious: you need electricity!

This certainly is not an issue on stage or in an exercise room. But what about outside? That is a typical use for drums: nature, beaches, evenings in parks, not to mention the legendary drum session at the beach in Valle Gran Rey on La Gomera at sun set…

That is why I decided to get a battery pack for my drum! Fine. Great plan. That is, actually, not fine, since it turned out to be not that easy to find a battery that combines a few requirements I had in mind…
