Linux by example – Verifying glibc build
After the build in the real system we need to verify that the correct libraries are used and the correct tools will create a viable executable in our new system before building the rest of the packages.
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.
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 we will cover what I use in my ceph cluster. I’m not an hardware reviewer but this is an example of what kind of hardware that could be used in a ceph cluster. Especially if you want to create a cluster for home use or testing.
We look into lambda functions in java using example code and understand what functions could help you with. Java has many new concepts that could help you, and lambda is just one of them. For example, you could create Suppliers that give you a value, Consumers that use a value, and then functional interfaces.
I’m trying to solve all the Advent of Code puzzles in this video series.
We solve today’s challenge at the advent of code 2020. Come join us and have some fun.
