Free software as in freedom of speech, not necessarily as in free beer. Maintainers also need to pay the bills.

It is also very resource efficient. I am running it on a Raspberry Pi 2 and it works flawlessly.

Yes, the comment was meant as criticism of the streaming era packaged as a joke

It‘s 2023, you can still listen to the same shitty music, because it is yours to keep.

  • Use sqlite instead of Postgres, MariaDB
  • Avoid enterprise software (Kubernetes, Elastic Search)
  • Only use projects with efficient programming languages such as Go, Rust, etc.
  • Try to run things bare metal
  • Lookout for projects which name themself minimal or light-weight

I use a Raspberry Pi 2 to self host a Dashboard written in Rust (Axum), a RSS reader called yarr and a music streaming server Navidrome. The latter two are written in Go and very resource efficient. The electricity bill should be under a Euro a month (6.4W max power consumption).

Thanks, and good observations. Many countries (Germany and the Netherlands for example) have statistics for every mode of transportation, which as you said is way more informative. I just quickly grabbed the first statistic I could find for the EU to be honest :D

Here is the data for Germany: https://www.umweltbundesamt.de/daten/verkehr/fahrleistungen-verkehrsaufwand-modal-split#undefined

For the Netherlands they have the data split by county which is very interesting. In the bike capital Utrecht still 50% of all passenger kilometers belong to car travel. I cant find the government website right now.

Oh mein Gott was? Das muss ich direkt ausprobieren. Ich kenne niemanden, der das nutzt :D Danke!

This pattern is true and passenger kilometers represent it just fine. There is no need to use the how often you use the train metric. Note that my two examples were there to explain the metric, not actual factual examples.

As an actual example: I take my bike to work and dont own a car, so my modal split is mostly trains because of longer distance trips, but I use the bike far more often. Frequencies only make sense if each occurrence is very similar (in quantity). For example: How often does one eat meat? Each meal roughly contains the same amount of meat (may be factor two or three difference). Here frequencies make more sense as more detailed statistics dont actually give more insights.

Thanks for your comment. Not wrong in the sense that the data is wrong or faked, but that the metric is not useful. Especially when better metrics are readily available for that region. Can you name me one prediction or result which you can infer from the frequency of train travel other than „fun facts“? (I am actually really curious :) ). With the modal split you can for example calculate CO2 emissions or estimate needed capacity increases if you want to replace one mode with another and much more.

This is the wrong statistic! It doesnt matter how often you take the train, but how far you go. There is something called a passenger kilometer. Someone traveling one kilometer by train makes one passenger kilometer, 6 people on a train going 10 kilometers makes 60 passenger kilometers. The same can be done for other modes of transportation. The modal split (the right statistic) then shows how much each mode of transportation is actually used. Here you can find the statistic for each country of the EU: https://www.eea.europa.eu/data-and-maps/daviz/passenger-transport-modal-split-2#tab-chart_1

A few examples why modal split is better than frequencies:

  • Environmentally CO2 is emitted per kilometer. Someone may bike a short distance everyday to work, but visits his parents who live far away every weekend by car.
  • On the way to work someone could take the car and the train on the same commute.

„Inzwischen“ ist es etwas untertrieben. Seit Jahren trifft es eher. Ich wundere mich jeden Tag auf der Arbeit warum Outlook dieses wunderbare Feature nicht einfach übernehmen könnte… Wahrscheinlich, weil es wirklich hilfreich ist. Stattdessen gibt es jetzt KI überall…

The project controlled by only one entity can affect users in the future. Moving forward Hashicorp could do anything with the code or licensing and nobody could do anything about it. It is good that something is happening now, when there is still the chance to do it.
