Advent of Code 2023 – Day 5

I’m trying to solve all the Advent of Code puzzles in this video series.

I go through a recent PR I created on the Ceph project. This contribution was something that solved a problem that really annoyed me when I’ve used the dashboard regularly the last weeks during a large upgrade/migration.

We look into the slim framework version 4 and do a quick review. I looked into the slim framework back in 2019 and this is a revisit where I review the changes and see if the latest version 4 has improved from the earlier slim releases.

We look at dockerizing our java build both in the cloud and in our local docker environment.

Java 18 is released, and the new JDK will bring a lot of interesting features to java. We go through all the features in 18 and talk about the performance benefits and some important caviats to keep track on in your code.

In this video we look at how to list keys in the S3 API using a Ceph backend. We also look at how to copy objects without downloading data. Last but not least we put it all together to delete with a prefix and move with a prefix.
