How to upgrade a PostgreSQL 16 instance to PostgreSQL 17

Sometimes, updating your system comes with unwanted occurrences- in my case I finally updated my Mastodon-instance from Debian 11 to 12 and found out that I had a struggle with the database afterwards.

What makes a good backup strategy? The World Backup Day 2025

Today, March 31, is World Backup Day once again. As is now a modern tradition, we need a special day to draw attention to an important topic: World Backup Day is once again a reminder of the importance of data backups and security - and, especially in these times, in terms of encryption.

Goodbye, Komoot? German app sold to Bending Spoons

There are apps that make a difference: For people who like to spend time outdoors, Komoot from Potsdam, Germany has always been a good option. Now the future may be unclear as the app is apparently being sold to Italy-based Bending Spoons, who have already bought WeTransfer and Evernote.

Internet Services: Vowing for an European change in times of a world going down the drain

With all these changes taking place in America, the former ambassador of the free world, it’s time to think about the personal consequences in terms of reliability towards services hosted there and therefore outside Europe.

Politics

Rise of the Triad

The world is in turmoil these days. America is being dismantled in no time at all by the Orange Goblin and his freaky Mars mate (along with human rights and the separation of powers).

Work

Be careful what you wish for...

... it might come true! If cocking promises turn out to be only 10% real and the real status quo is more of a desaster than the next leap in your professional life - you may have been fooled!

Sports

Three fights in nine seconds

The hate has reached sports. Even the idea behind the competition on the court, track or ice cannot hold back the recently ignited flame of hatred fueled by the Trump administration.

My default apps starting 2025

There have been many lovely events in the Internet over the years and one to cherish especially is the one where users simply blog about their favorite standard apps they are using.

Music

My music albums of the year 2024

At least one guitar is good, a little nostalgia is always nice, two guitars are better and the extreme is not always the best choice: My (metallic) taste is omnipresent, but also has occasional outliers into the one or other “more leisurely” realm.a

The electronic patient file - the expected failure with an announcement

I have objected. For myself, my wife and also for our daughters. I smelled the rat months ago: The “advantages” of the electronic patient file ("ePA" in German), which was driven through the health insurance village like the new proverbial pig, were so obvious!

The Mac Pro 2013 - when nostalgia finally catches up with you

It's a self-experiment paired with a hefty dose of nostalgia. My first Mac was the iMac G3 in Bondi Blue, I always wanted the iMac G4 (the “lamp”) and found the silver PowerMac G4 instead, with which the Mac journey then continued.

Data retention - the next round begins

The troublemaker FDP in the so-called German “traffic light government” is gone, and SPD Interior Minister Nancy Faeser wants to take advantage of this opportunity and is going straight back into the thick of things when it comes to “data retention”.

Music

Everything back to zero - LINKIN PARK - “From Zero”

Letting go is sometimes hard and I'm a quite nostalgic person. The return of LINKIN PARK seven years after the Chester Bennington tragedy was therefore initially a sacrilege for me.

Playlisty for Spotify: Migrate Apple Music playlists to Spotify

Switching from one service to another is often less of an ideological issue than a technical one: when you switch from one music provider to another, for example, your playlists can fall by the wayside.

Apple acquires Pixelmator

There is software that does not come from the respective manufacturer of the operating system and can definitely be described as “essential”. On the Mac, for me this is Pixelmator (Pro) and Photomator, which have now found a new home at Apple.

Traveling

Not all those who wander are lost

50 km on a single weekend, two stages. 935 metres in height in total. Enough time to re-focus once again for a short amount of time, pulling the plug for two consecutive days and think about encountering and mastering obstacles.
