I look into the Ceph Rook orchestrator that is the pre-cursor to the Ceph admin tooling. This installtion uses an Kubernetes installation in order to deploy a cluster and scale it up and down. Sadly the Ceph GUI don’t have much control so all changes are done with Kubernetes manifests from the command line.

I aquired a Dell R420 which will not fit in my rack at all but I guess now that I have it I need to do something with it. There is quite some power in it but not efficient power.

I talk about some maintainance I had to do recently where we switched the public network of our monitors, removed the cache tier and remove massive amount of objects and all the problems we encountered and handled.

We look into pieces and what features currently are available. Is it a tool for your development workflow or is it to early to use/know.

I switched to Linux this year and have been running it for almost a year. In this video we look into DistroSea which is a site for trying out different distros before you take the plunge into the world of Linux. I review the package managers, GUI elements and overall usefulness.

In this video looks into how to expire objects from object storage and also move them to another storage class using rules and scheduled jobs inside the rados gateway program.

In this video I go through a minimal client storing data in Azure Blob Storage. Talking about the differences with S3 and what to look out for and challenges to get it working.

In this video, I will teach you how to store data with ETCD, set up an ETCD cluster, and recover from a disaster.

In this video, we look into the database library Galera for MySQL or MariaDB. It enables replication over multiple hosts where each host is a master and replicated to the other hosts so it’s eventually consistent.

In this video I look into htmx and the workflow to write a simple notes application with a simple backend API. htmx is a really cool way to write code in pure HTML and just add one small javascript library to get an reactive page.

In this video we look into the new preview features for connecting java applications to native libraries and run functions. We test both running against libraries loaded in the system and we also load a custom library we built from C code.

In this video, we look into the Ultralytics Yolo framework. It enables you to run a pre-trained Yolo algorithm and retrain it for your particular use case. Using this model, you could easily create a new model to detect your favorite things in an image and create location boxes over the objects.
