Album Review: Era Capricorn – I Wander Alone

This will be the first music review I have ever done, so please do not roast me too much 👶


The reason why I have selected this record to be my primer for this is the fact that I’m not only a close friend to the artists but also I was utterly impressed with the results.

The record is self-produced, -released and -sold by the band’s official shop, only, created solely for this record (so far! 😉)

Process a textfile line by line in Bash


One of the most common tasks when working with Bash-scripts and the Linux shell is text processing like filtering, selection, transforming, …

Often, these texts come from text files like CSV, log files, and so on. If you are an experienced user who is doing this on a daily basis, typing these kinds of command chains often feel like they are coming from “muscle memory” more than from your brain. But most of the time, you need only parts of these lines, like “the 5th to the 7th field” or some regular expressions match; these are usually quite easy to catch using a combination of the well-known tools awk, grep, cut or sed.
But: How to iterate (loop) over each line of a file in Bash and use that value for your processing; like, if you want to preserve only lines, matching a specific pattern or divide the script of a play into separate files per role, for example?

Fix missing Google calendars in Evolution / CalDAV

Google Calendar and Evolution Sync

Me and my wife both use Google calendars to organize our daily schedule. Also, we share these calendars with each other, to see each other’s appointments. This way, we do not clash each other’s plans by accepting appointments in the same, concurrent time slots.

Recently, we found that not all of her calendars were offered to me in Evolution. After some digging, I found the solution and I’m going to explain it in this article.

More recent Python in Enterprise Linux like CentOS and RHEL


This article describes what “Enterprise Linux” is and how to add a more recent version of Python to it than those available in the base package repository.

What is “Enterprise Linux”?

General definition

CentOS and RedHat Enterprise Linux (RHEL) both are counted as one of the so-called “Enterprise Linux” systems. This term is an artificial noun, which has different meanings. In general, this describes Linux distributions, which are targeted at the commercial market thus putting a strong focus on reliability and long lifecycles.
CentOS, RHEL and SUSE Linux Enterprise Server (SLES) usually maintains a release for 10 years; RHEL and SLES even offer extended support contracts for additional years of support. That means these distributions offer at least twice as long support for a version than Ubuntu LTS versions does (which usually is ~5 years).

Hello World!

Time to start a new Blog with a “Hello World!” post!

Let’s start with some technical, personal and historical background about my IT journey so far (even no one will be interested enough in this to read the whole article, though. And you know why I do it anyway? Because I decide so, it’s only about me to decide what is put here and what isn’t and there’s nothing you can do about 😛).
You digital-native-social-network-scum can search for some “Dislike 👎 or Report 📢” buttons as long as you like – this page was made by elders for elders 🧓 (quoth the 35 years old author), who went through the dark ages of the Internet, including connection breakdowns, because some other member of the household picked up the phone and interrupted your dial-up connection.

My first steps into the IT

I started to explore computers in 1994/1995  Continue reading “Hello World!”
