Activate MS Office 2019/2016 for macOS - Microsoft_Office_2019_VL_Serializer

Office 2019 above

2019-06-03

Note that Office2019 DO NOT support activate via simple copy/paste plist license file which is the simplest way to activate Office 2016. Fortunately, you can also use the VL Serializer tool, just install Office 2019 and Serializer, then run Serializer to activate.

auth with microservices

Authorization and Authentication are hard. when you only have to implement them once (as you do within a monolith) instead of over and over again, it makes the developer happy :-), and maybe leads to less implementation failures.

When you have a bunch of microservices, this is something that has to be considered.

Implement it once or in every microservice, or something in between?

Here's an example of how to debug Mocha v4 if it hangs.
