  • Maybe for your use cases that’s OK, but there are many situations where the size and ease of upgrading provided by shared libraries is worthwhile. For example it would suck to need to push a 40+ GB binary to a fleet of systems with a poor or unreliable internet connection. You could try to mitigate this sort of thing by splitting the application up into microservices, but that adds complexity, and isn’t always a viable tradeoff if maximizing compute efficiency is also a concern.



  • The main issue I have with rust is the lack of a rust abi for shared libraries, which makes big dependencies shitty to work with. Another is a lot of the big, nearly ubiquitous libraries don’t have great documentation, what’s getting put up on crates.io is insufficient to quickly get an understanding of the library. It’d also be nice if the error messages coming out of rust analyzer were as verbose as what the compiler will give you. Other than that it’s a really interesting language with a lot of great ideas. The iterator paradigm is really convenient, and the way enums work leads to really expressive code.












  • A dedicated server is needed because something needs to keep a catalog of the smart devices available on your network and ideally be accessible to many people in one household. You could make a system that went phone -> device but you would need to set up each device on each phone you wanted to use, which isn’t a great user experience. You could also run into issues where devices would need to handle multiple conflicting commands from different users coming in at once. Since smart devices are usually trying to use as little power as possible, that extra complexity would hurt you in that department. The third reason is that having a separate server enables automated workflows that would depend on an always online server that orchestrates multiple devices. For example, let’s say you have some automatic insulating blinds, a smart thermostat. You want to raise and lower the blinds to maximize your energy efficiency. Since you have the dedicated server, that server can check the temperature set point of your thermostat, current weather, and sunrise\sunset times. If it’s sunny out, and your set point is higher than the outdoor temperature, the server can raise the blinds to let warm sunlight in, and vice versa. If only your phone could control the devices a workflow like this couldn’t work when you were out of the house.
