Hey fellow nerds and wanna be nerds 👋
Another week has passed and we had a warm and sunny week here in Germany. Despite that I used my time wise to update this blog. The next days I want to write down how I have setup this blog but that is next week I guess.
I have setup my Linux Desktop PC with Ubuntu again and have written down some common tools I always install here: Common Tools and Apps I use on my Linux Machines. Might be interesting for the fellow Linux users out there.
This blog runs on Ghost and an update was due which I postponed because this gave me and others on the internet some trouble. If you come from MySQL 5 and updated to MySQL 8 and a certain Ghost version you will most likely have the same problem. Here I have written down what needs to be done and why for a docker setup: Ghost migration fails - How to migrate the default collation from MySQL 5 to MySQL 8
Here is what I found interesting this week.
Container learning resource
Not sure how, but I stumbled across this huge deck of training material about Docker and containers!
Here is the HTML rendered version: https://container.training
And the GitHub repository for the slides:
I remember having a hard time getting into containers around 2016. Have looked at the slides briefly (over 800!) and it seems a good learning resource!
I have done some self-hosting with containers on my NAS and learned so much. That has opened the path to Kubernetes later on which I which is part of my work now.
Have fun learning containers, it sure is damn helpful to know Docker, containers, and the ecosystem around it!
Raspberry Pi SD Card Corruption
A couple of Raspberry Pi have made it into my possession. One was working at my parents home as an ad blocker with AdGuard. A few weeks ago that died because of power cable ripping in and out. I told them to not do that, but I should have know better. 😅
At the same time I saw an article about SD Card corruption regarding the Raspberry Pi by coincident. And the thing about the internet and bad reviews: They do not change because people always repeat what people said before without doing new research. Especially with a lot of time passing, the fact could change but the general opinions stays the same. So have a read about the actual problem of SD Card corruption on the Raspberry Pi, it is a really interesting read:
That is it for now.
