Java ALWAYS passes by value (and it is ALWAYS an interesting discussion)

Always good as a refresher.

So, when calling a method

For primitive arguments (int, long, etc.), the pass by value is the actual value of the primitive (for example, 3).
For objects, the pass by value is the value of the reference to the object.

Lombok not generating getters and setters

I've correctly installed Lombok on my STS IDE by using the jar file, but no way it was working. The file was moved to Eclipse folder: just copying it to the Plugins folder and restarting was enough to fix my issue.

Multiple controllers with Spring Boot

Remember, when you want to have multiple controllers with Spring Boot, you should always name them differently in the annotation, otherwise they will not work So these two together will NOT work (or just one of them will work) These two instead WILL work.

When adding a property to graph-tool don't forget this

When you are adding a new property to a graph-tool graph (https://graph-tool.skewed.de/) is_node_customer = network.new_vertex_property("bool") weight = network.new_edge_property("float") you should never forget to add this network.vertex_properties["is_node_customer"] = is_node_customer network.edge_properties["weight"] = weight Otherwise the properties will not saved or stored together with the graph and you will lose a lot of time
