Es ist egal, aber

Tocotronic is one of the bands I listened to during my teens/twenties. That dates me, that dates the band.

It’s very german. You’ll find their music on most streaming platforms. I recommend starting with the albums “wir kommen um uns zu beschweren” and “es ist egal aber”.

Anyhow. Now one member of the band starts a podcast!

Jan Müller ist seit über 25 Jahren Mitglied der Band Tocotronic. Er ist mit dem Format des Interviews bestens vertraut und kann sich als Fragender gut in die Perspektive seiner Gäste hineinversetzen. Die persönliche Auswahl seiner Gesprächspartner*innen bildet die Grundlage für authentische Gespräche, die stets von Interesse und Respekt geprägt sind. Mit “Reflektor” startet Jan seinen ersten Podcast.

easily draw text based flowcharts

As I am mainly producing text and markdown notes throughout the day I am always interested in ways to quickly create simple text-based flow-charts.

I did write about a couple of tools to accomplish this previously but I want to take note of the most recent addition to the toolbox: ASCIIFlow Infinity.

You open it in your browser and start drawing with the simple tools provided.

When you are done you export it to plain text and do what you feel like with it.

Here’s a feature overview:

retrofit an old printer to be available on the network

In 2007 I had become proud owner of a Samsung ML-2010 mono laser printer. It’s done a great job ever since and I can recall changing the toner just once so far.

So you can tell: I am not a heavy printer user. Every so often I gotta print out a sheet of paper to put on a package or to fill out a form. A laser printer is the perfect fit for this pattern as it’s toner is not going-bad or evaporating like ink does in ink-printers.

So I still like the printer and it’s in perfect working condition. I’ve just recently filled up the toner for almost no money. But – but this printer needs to be physically connected to the computer that wants to print.

As the usage patterns have significantly changed in the last 12 years this printer needs to be brought into todays networked world.

Replacing it with a new printer is not an option. All printers I could potentially purchase are both more expensive to purchase and the toner is much more expensive to refill. No-can-do.

If only there was an easy way to get the printer network ready. Well, turns out, there is!

First let’s start introducing an opensource project: CUPS

CUPS (formerly an acronym for Common UNIX Printing System) is a modular printing system for Unix-like computer operating systems which allows a computer to act as a print server. A computer running CUPS is a host that can accept print jobs from client computers, process them, and send them to the appropriate printer.


A good, cheap and energy-efficient way to run a CUPS host is a Raspberry Pi. I do own several first-generation models that have been replaced by much more powerful ones in the previous years.

So I’ve taken one Raspberry Pi and did the set-up steps: Installing the Raspberry Pi Print Server Software.

And now – what did I get?

I got a networked Samsung Laser Printer. No thrills, no problems at all.

train sounds in Japan

If you’ve ever been to Japan you must have noticed that everything and anything makes sounds and talks. Elevators, escalators, doors, train stations, gates, vending machines – you name it, it makes sounds and talks.

It’s so apparent but yet quite comforting that I enjoyed it. It became an additional channel of information without the need of point-and-call all the time. Highly effective for me.

Japan utilizes sounds to a degree that every detail seems to count. Take the station gates you rush through to get to your train platform. It’ll sound differently depending on how you pay, what status your ticket had and even how close your IC-cards balance is to being empty.

Or just the fact that the ticket gates make sounds at all to make you find them easily.

A good portion of this sounds you can find on places like YouTube or specialized websites. One of those specialized websites is

For some routes and stations you find here:

  • Station melody – departing and arrival melodies that are played on the occasion
  • In-car chime – chimes played before and after information broadcasts mainly in the Shinkansen and limited express trains.
  • Door opening and closing – doors make sounds too!
