Advent of Code 2023 – Day 14
I'm trying to solve all the Advent of Code puzzles in this video series.
We look into high availability using Heartbeat and DRBD. Heartbeat is a software to monitor and failover when a machine is unresponsive and DRBD can help you replicate data between machines making your setup highly available. This solution can help you doing maintenance work without downtime.
We build a rack and I walk about what goes into the building process and showing the process. We also talk about networking like keystone jacks and cable management.
In this video i will do a quick introduction to rust and introduce some important concepts that rust uses to handle packages and build your executables. Rust is a programming language that have been hyped since it’s introduction. It mixes good structure with execution performace, type safety and memory management.
We look into Ceph encryption in a cluster where each OSD can be encrypted and the keys store externally in order to ensure data integrity and safety.
We look into building Ceph from source. A build of Ceph is built from Github code using normal tooling. But I need to build my own packages as there is no new packages built for the Raspberry PI arm processor. There are quite some challenges and interesting things to keep in mind when building Ceph…
I show you how I test parsing functions in java using file testing; this is where I could add more files for each test case that I want to run. Testing this way makes your workflow quick and easy. Just add a file and then start to solve issues.
