A reader wrote me a mail and asked what the general direction of this blog is going to be. He wondered about the “flood” of formulas lately. Which, in his opinion, have nothing to do with Linux. In general, his impression was that I seemingly have lost my interest in core Linux topics. He, a German, also complained that I write my posts in English.

My first reaction was: I appreciate that some of my readers care. The criticism is justified. And it deserves an answer and some explanations. The easiest part is the question regarding language.

According to my provider and my own blog-statistics 78% of page requests to this blog come from abroad, i.e. from countries outside Germany. Most requests stem from US-systems. Before Russia’s imperialistic war against Europe there also were connections (and permanent attack trials) from both Russia and China. Their percentage has declined (fortunately). Anyway, the majority of page requests comes from outside Germany. Therefore, I try to write in English. My English certainly is not the best, but it is still easier to read for those who are interested in my posts’ contents. And obviously, these are not German readers. So, I will not go back to German again.

Now to the question regarding the declining number of posts related to Linux. In the time when I worked as a free-lancer (up to 2018), I had some German customers who cared about Linux. It was in my own interest to dig a bit deeper as usual into topics like “virtualized VLANs”, firewalls etc.. The articles on these topics are still the most read ones in this blog.

But then I started to work as an employed consultant for IT-management topics in a Windows-dominated company. I simply had no chance and no time to continue with hard core Linux topics until the end of 2022. The only connection that came up was related to minor Machine Learning topics. Since my retirement I again use my private Linux systems – but what I need there simply works. No need to dig deeper at the moment. I intend to shift all of my HW-platforms and in the wake of such an endeavor typically some Linux topics come up, but all of this requires a period of money saving first. The same holds for a private project concerning central Linux-based audio-station. (Side remark: Due to the systematic destruction of the social system in Germany, ironically and mainly by the politics of social democrats, ca. 10 million of the persons going into retirement the next years will get significantly less than 1500 Euros per month. These are official numbers of the German government. I am on the edge of this wave.)

A second point which obviously has an impact on this blog is that I have an education in physics and an inborn interest in math. One of the best aspects of retirement is that you gain a lot of freedom regarding your real interests. No employer longer forces you to focus on things you only work with to earn a living. In my case the physicist woke up in spring 2023. I started to read a lot of books on theoretical physics and cosmology. To find out that I needed to revive some university level mathematics. At the same time I got interested in some admittedly special aspects of my own ML-experiments and network simulations in general. And suddenly you find yourself applying some basic linear algebra and calculus again. An easy but not very thoughtful way to start collecting some simple, but useful results was using this blog. I admit: It has turned the blog’s focus away from Linux.

The solution is clear: This blog has to be split up. I will do this as soon as I find some motivation for the boring task to set up a new blog, database, etc. For the time being I have changed the subtitle of this blog to indicate that other topics have come up.

What I cannot promise is that Linux topics will dominate my interests in the future. As said: What a retired person needs on PCs and laptops normally works perfectly under the control of Linux. Thanks to all the fantastic people of the Open Source community.
