Things worth looking this week.

1. Scripting! Two tools this week:
   1. Bashly, a tool to create Bash scripts easily
   2. Ever wished to use Python in Bash? Would you choose the Python syntax over sed, awk, ...? pz can be the tool for you.
2. Lurnby, a tool to annotate the web just open sourced

Context: Spring microservice application to be deployed on K8s via helm + boring Friday

In this scenario, you end up writing the SAME configuration string in a lot of places:

1. On at least 2 application.properties (main and test)
2. On the final, helm-generated application properties (or in the relevant environment variable if you use them in place (1))
3. On the default K8s values.yaml used by helm. Possibly on other yaml file too, all documented a bit to be kindly with the K8s SRE.
4. On the relevant Java code, as a @Value annotation to finally use that damn config.

These configuration are not particular exciting: they are all similar, some case can change but, really, ChatGPT could do it for you. If you have 4 parameters, you end up losing half an hour to do everything and test it. We can do better, for sure^TM
