I use Pihole and block all my appliances and other traffic I deem unusual or unnecessary. Its also very useful forensically if I suspect shenanigans on my network. I recommend it to everyone.
As long as the code isn't abstracted more han 1 or two layers deep, it's commented in places where the control flow isn't that intuitive, and follows best practices for whatever the kids of languages is, it doesn't matter if it's home spun. Just being "home grown" is not synonymous with bad software. At the end of the day, just using frameworks are no guarantee that the code is readable and maintainable. Usually by the time someone is looking at your code to rewrite or update it, what seemed like an awesome choice of framework at the time can end up being a nightmare to parse as documentation has dried up, forums that were the sole source of knowledge are offline, and now your once amazing code is just garbage to the poor coder trying to make sense of the random abstractions of the framework.
My mother is from Jamaica and I have a similar story. I was in Jamaica last summer visiting my grandmother. We were sitting on he porch and she was telling me how disappointed she was in her sister, who she raised as a daughter, as she "gave" the daughter of the women who helped raise my mother to her sister. I remember being struck by that language. I began wondering what the real nature of the relationship between my grandmother and the woman I affectionately knew as "aunt erma." I wonder how common these kind of arrangements are around the world.
Thanks. I've been reading up on OS Dev and static and dynamic libraries and have been trying to wrap my head around why an ABI change could blow things up.
