I am not surprised you mention "missing generic". It can be done by using interface. As "no inheritance", you can use encapsulation. As "broken package management", you can use "vendor". Above are all about how to engineer application. There is no only one way to solve it. (if you are from java/C++, I don't think those OOP concepts are the king rules) As of "Google Guidelines", I would judge you just entered the beginning level of software engineering. (You dont know how much pain without those) In conclusion, I think you blog title is just making horrible attention.
